Changes in 1.2.38 (2019-03-02):
Deprecate MILS as angular units. Survex has long support MILS as an alias
for GRADS. However, this seems to be a bogus definition of a "mil" which
is unique to Survex (except that Therion has since copied it) - there are
several different definitions of a "mil" but they vary from 6000 to 6400 in
a full circle, not 400. Reported by Andy Edwards.
Fix segfault for *include "". This isn't useful, but shouldn't crash. It
now reports "file not found" instead.
Use isnan() to check for not-a-number. This is cleaner, more robust and
more efficient than formatting the number as a string and checking for
"NaN" or "nan" in the result.
Avoid unused variable warning when compiling from source with modern ffmpeg.
Drop support for wxWidgets < 3.0. 3.0.0 was released over 5 years ago and
should be easily available everywhere by now. I'm no longer easily able to
test with wxWidgets 2.8, and this allows a significant amount of cruft to be
(Linux version): survex.spec: Fedora have removed gcc from the default build
environment so need to explicitly list it in the BuildRequires tag. See
https://fedoraproject.org/wiki/Changes/Remove_GCC_from_BuildRoot for more
information. Patch from James Begley.
Changes in 1.2.37 (2018-11-18):
Add basic "Colour by Survey" feature. The colours used aren't currently
Fix export of splays. Patch from Thomas Holder.
Fix KML export to avoid invalid geometry when a tube intersects itself.
Patch from Robert Jones.
(Unix version): Fix to work under Wayland by forcing the x11 GDK backend
for now. This is a workaround until wxWidgets OpenGL support is updated
to work under Wayland. Reported by Philip Balister.
Fix warnings about using deprecated functions when building movie export
code using FFmpeg 4.0.
Compass MAK files: Handle fixed point coordinates in feet - previously the
units were ignored and the coordinates assumed to be in metres.
Previously the first byte in a MAK file was ignored. Typically MAK files
start with a comment, and since cavern currently ignores lines that start
with characters it doesn't understand the meaning of, this bug would often
Fix exporting of passages, walls and cross-sections by running the code
aven uses to decide how much to rotate each cross-section. Previously all
cross-sections were aligned West-East. Reported by Robert Jones.
Default to .pos output if the program name is 3dtopos, and install a second
copy (or hardlink under Unix) as 3dtopos. This provides compatibility with
current releases of Tunnel. Reported by Becka Lawson, Wookey and
Fix some German translations. Patch from Thomas Holder.
(MacOS X version): Fix aven-create-app to not delete converted icons.
Typo spotted by Robert Jones.
Improve documentation for *team. Document the requirement to quote names
unless a person is identified by just one name. Document that the roles are
optional, as that information may not have been recorded, and to align with
therion's team command.
Changes in 1.2.36 (2018-07-18):
Add support for exporting as a CSV (Comma-Separated Values) file.
Support exporting KML with altitude mode "clamp to ground". In this mode,
the altitude in the data is ignored and it's rendered on the surface of the
terrain. This is useful if your KML viewer renders the terrain as opaque
so underground data isn't visible. Rendering cave passages on the surface
isn't great, but is better than not being able to see them at all. This
option may also be helpful if you want to see where to look on the surface
for new entrances.
Highlight surveys with a white loop as the mouse is moved over them in
the survey tree. This is akin to how we highlight a station with a
white ring, and allows restoring "double-click survey in tree to zoom"
which temporarily required a quadruple-click in 1.2.35.
Only show checkboxes in the survey tree for surveys not stations.
Fix wxWidgets assertion if the user tried to select additional surveys
to show via the right-click menu.
Fix multiple survey filtering when both a parent and child survey are
selected. In this case it makes most sense to show all child surveys of
the parent, but we actually showed a slightly arbitrary subset of the
child surveys of the parent.
The checkbox area in the survey tree is now included in the area which
is considered by mouse-over updates such as highlighting the station or
Fix display of double quotes in cavern log window (they were being replaced
with control character 0x16 due to a typo in the code).
Add shortcuts to buttons in cavern log window.
Eliminate use of gluErrorString() function which eliminates some
deprecation warnings when building on macOS.
Reject multiple --survey command line options for now (only the last has
been used for a long time, but now we actually support multiple survey
filtering this matters more).
dump3d: Report station flag "WALL", which was added in 1.2.7.
Minor translation updates.
Update manual for Microsoft Windows changes.
tests/: Add test coverage for warnings about suspect readings
Fix warning when compiling with clang.
Changes in 1.2.35 (2018-07-03):
Viewing can now be restricted to multiple surveys. Use the right-button
menu on a survey in the survey tree and select "Show" to enable checkboxes
for that survey and all its siblings. Only the selected surveys are shown
on screen, printed and exported.
Don't open a survey when its name is double clicked. This was happening
due to code added to "allow double-clicking to work on wxMSW >= 2.8.11".
However, reverting that change still seems to allow double-clicking to work
on both wxMSW and wxGTK, but fixes the unwanted additional opening of the
Pick initial survey scaling based on whichever of the window width or
height gives the smaller scale. Previously we always used the window
width, which can result in parts of the cave being outside the initial
view. Reported by Wookey.
Drop ability to specify a PROJ string in the export dialog. This was added
to allow exporting to formats such as GPX before we added support for
specifying the projection in .svx files, and that support is now mature.
DXF export now uses 2 decimal places (was 6) for the bounding box, for
consistency with the precision used for coordinates.
Fix handling of surface flag during export. In formats which discriminate,
legs could previously have got assigned the wrong status.
Fix bug which probably prevented aven starting when OpenGL double buffering
is unavailable. This is unlikely to affect any common configurations.
(Microsoft Windows version): Fix loading of 3d files with non-ASCII
filenames. Issue reported by Matic.
(Microsoft Windows version): Fix incorrect display of some toolbar icons.
Probably broken since 1.2.17.
survexport: New command-line export program which uses aven's export code.
Replaces 3dtopos, cad3d and findentrances, since it can do all that these
tools could do, plus much more.
Merge more Spanish i18n updates from Evaristo Quiroga.
Minor updates to various other translations.
(Microsoft Windows version): Fix packaging to include wxWidgets translation
files like it was supposed to, which fixes a few missing translations. This
was probably broken by changes in 1.2.8. Reported by Evaristo Quiroga.
(Microsoft Windows version): Drop two options from explorer bindings.
"Convert to DXF" and "Convert for hand plotting" have both been supported via
aven for a while, and that's a more useful way to access them as you can
control what gets exported.
Changes in 1.2.34 (2018-03-24):
Changes in 1.2.33 (2018-03-22):
Reliably disable scale bar in perspective view. This is supposed to happen
(because the scale across the screen varies in perspective view) but
actually the scale bar stayed around until an update was forced for another
reason. Spotted thanks to Pedro Silva Pinto.
Make "no date"/"not in loop" colour grey. The white was a bit bright and
made it harder to see the legs that had colours. The grey now used is
within the brightness range of the other colours. Fixes #94, reported by
Fix KML export - exporting both survey legs and station names resulted in a
malformed KML file. This bug was introduced in 1.2.30 when support for
exporting passages and walls was added. Reported by Erin Lynch in #90.
Consistently use 2 decimal places for altitude in KML output. Some places
used 8 decimal places which is appropriate for lat and long, but clearly
overkill for an altitude in metres and increases the file size
Right-align bearing widget in print/export dialog. The change to allow the
value to wrap round from 360 to 0 in 1.2.27 inadvertently made this control
left-aligned (due to incorrect wxWidgets documentation of the default style
for this control).
(Unix version): Work around wxWidgets bug so that custom cursors work
(Unix version): Update GTK version reporting - report GTK3, and don't
bother to report subversions of GTK2 (it seems to be fairly arbitrary
which subversions wxWidgets defines constants for).
Update code to work without warnings when using wxWidgets 3.1.0 (the
current development version).
Make movie export code compatible with upcoming FFmpeg 3.5 release.
It should still work with the older versions that worked before this
change. Reported by James Cowgill in https://bugs.debian.org/888334
Warn about 2 digit years. We can't change the assumption that these are
19xx without risking breaking existing datasets, but the further we get
into this century, the more likely such an assumption is to catch someone
out. The warning can easily be quashed by explicitly adding the assumed
The Spanish translation is now up to date once more, thanks to updates from
Merge French translation updates from Jean-Marc.
Fix transposed German Northing and Easting labels. Fixes #95, reported by
Fill in missing translations of "Easting", "Northing", "E" and "N" for
Bulgarian, Greek, Hungarian, Polish and Russian based on other existing
Align .pos file headings better with columns of coordinates below for
Indonesian and Polish.
Fix handling of the message string "error" before messages loaded. If
there's an error loading messages, we need this message to report it.
Reported by Martin Sluka.
Fix a few compiler warnings.
img library: Fix extracting leaf survey name for survey title. When there
are three or more levels of survey, we were taking everything after the first
dot rather than everything after the last dot.
Fix problems with testsuite on macOS:
cavern.tst: Skip "ONELEG" testcase on case-insensitive filing systems
- this test isn't meaningful unless the filing system is case-sensitive,
but happens to fail if it isn't.
cavern.tst: Workaround limitations of Apple's sed.
aven.tst: Fix not to hang on macOS.
smoke.tst: Remove aven testcases which duplicate those in aven.tst.
Clean up handling of support files in relocatable installs - this is now
detected at run time on macOS.
Split out macOS Aven.app creation into a make rule so it can be easily used
by the homebrew formula.
Stop checking wx-config --ldflags as this option was removed in wxWidgets 2.6
and we currently require 2.8 or newer.
Changes in 1.2.32 (2017-07-08):
Make splays on printouts a darker shade of grey. Reported by Erin Lynch
and Anthony Day.
In export formats which include 3 dimensions (DXF, PLT, GPX, KML, JSON,
POS), the value in the Z dimension was negated. Bug introduced by fixes
for export of rotated plans and tilted elevations in 1.2.27. Reported by
Erin Lynch in #89.
Ignore viewing angles for export formats which work in 3D. When the
rotation and tilt controls are hidden in the export dialog we were still
using their values to transform the data, so if you set them with for one
export format which support them, then switched to an export format which
doesn't, you'd get bogus coordinates in the exported file. Bug probably
introduced in 1.2.27 by fixes for exports of rotated plans and tilted
Fix exporting to skencil and Survex .pos formats. When aven's export to
.pos was added in 1.2.19, the ordering didn't match up and since then .pos
export has produced skencil files and vice versa.
Don't leave terrain on if loading terrain data fails. Previously if you
clicked the terrain icon (or via the menu) with no terrain loaded, but no
terrain got loaded (e.g. because the survey data lacks an explicit
coordinate system, or because the file failed to load, or because you
cancelled the dialog) then the terrain icon/menu item was still changed to
Disable texturing while drawing terrain. Previously the terrain got a bit
darker when "Textured Walls" were enabled.
Force a refresh when "Textured Walls" are enabled or disabled. Previously
the display wouldn't update right away.
Building from source now requires a compiler with decent support for C++11.
If you're using GCC, then GCC 4.7 should suffice. This should not be an
onerous requirement - e.g. Debian wheezy and Ubuntu trusty both have a recent
enough GCC. If special options are needed, these should get probed for and
automatically. Fixes building 1.2.31 with GCC < 6, reported by Wookey.
Changes in 1.2.31 (2017-07-01):
Use superscript 'g' symbol instead of word 'grads' in status bar. This
conserves the limited space available, and we already do this in the
compass and clino indicators so it's more consistent too.
Show one decimal place on measure line bearing. Pointed out by Benedikt
Hallinger on the therion list, though I'm sure this has been asked for
before by others.
Show gradient of the measuring line when both ends are stations.
Allow selection of text in cavern log window. Selection was disabled in
1.2.28 because it seemed you couldn't actually copy selected text to the
clipboard, but retesting this now actually works fine for me, both with
current git master with the change reverted, and with code just before the
More robust parsing of cavern output (cleanly handle context highlighting
which extends beyond the end of the line).
Allow showing duplicate legs as dashed lines or hiding them entirely,
with dashed now being the default. Implemented by Patrick Warren.
Also allow "Dashed" for splays and "Faded" for duplicate legs.
Splay legs in surface data are also shown faded.
Check environment variables VISUAL and EDITOR when looking for editor to
use when a warning or error is clicked on in the cavern log window. The
specified editor may have a GUI or need to run in a terminal, so we have to
special-case each editor supported, and that means we can pass extra
options needed to position the cursor on the appropriate line/column.
Currently these editors are supported: gvim, nvim, vim, gedit, pluma,
emacs, nano, jed, kate. Suggested by Wookey.
Fix handling of non-square terrain data files - the X and Y dimensions were
swapped. Reported by detrito.
Improve parsing of DEM data with .hdr file. Use documented defaults for
more values, and where we only support a subset of values (or a particular
value) check for unsupported values in more cases.
When colouring by depth, fix colouring and texturing of polygons which
cross depth bands. The previous problems were most obvious with high
chambers and long legs down deep pitches, especially in for surveys without
much vertical range.
Support for drawing blobs using point sprites was added in 1.2.28,
but caching that this worked wasn't hooked up properly so the test to
see if this worked would happen at the start of each run. This is now
cached as intended which should reduce start up time a little when blobs
are drawn in this way.
Fix drawing of crosses with lines. This is a fall-back case which is
rarely used as most OpenGL setups will handle a better method, but it was
resulting in crosses with a four-pixel square in the centre - now the
centre should be a single pixel.
Allow *data with no arguments to reset the current style - useful for
entering passage data where there are side passages.
Fix hang processing file without newline at end. This bug was introduced
by changes in 1.2.28. Reported by Mark Brown.
(Mac OS X and Microsoft Windows versions): Build with newer version of
PROJ library which fixes buggy handling of *fix with lat-long coordinates.
Also add a testcase to the testsuite to alert users building for themselves
with an affected PROJ version on any platform. Reported by Ross Davidson.
Fix cavern to handle Compass .DAT with no survey team. Previously this
resulted in the bogus error: Expecting numeric field, found "FROM"
Reported by Erin Lynch.
Handle UTF-8 "BOM" at start of .svx files. Unicode doesn't recommend its
use, but Microsoft stuff seems to like to create files with it in, and the
error cavern currently reports for such files is very confusing, so it
seems best to just handle it. Reported by Rob Eavis.
Change a couple of messages to use double quotes for consistency with all
Now runs a bit faster.
Splays are now carried over the extended survey. The current handling
is simplistic, but should do a good enough job to be more useful than
discarding splays. The splays at each station are all rotated together
based on the bearing between the stations either side of the current one
along the first path extended through that station. This nicely handles
dead ends and the situation at the top or bottom of a pitch, and should
tend to pick an angle close to the passage orientation along a traverse.
It's weakest at junctions. Feedback (especially examples which could
be handled better) most welcome.
French translation is now up to date again, thanks to Jean-Marc.
Remove erroneous menu shortcut markers from Polish translations.
Fill in some missing translations in several languages by using message
translations from therion.
Add note to *fix documentation to clarify the coordinate order with *cs
long-lat. Issue raised by Ross Davidson.
Fix errors in documentation of *units: "DEG" should be "DEGS", and
"MINUTES" has been supported for ages but wasn't documented. Reported by
Fix a few typos in the documentation.
Fix compilation warning with recent GCC.
Changes in 1.2.30 (2016-10-03):
(Microsoft Windows version): Fix crash when trying to print or export
(probably introduced in 1.2.28). Reported by Brian Clipstone.
Report error if terrain file contains no terrain data in area of survey.
Suggested by detrito.
Errors when writing an export file were reported with the wrong filename
- the .3d file, not the filename we were trying to write to.
Export to KML now supports exporting passages, walls and cross-sections.
Addresses the remainder of ticket #4.
Add man page for dump3d.
Changes in 1.2.29 (2016-09-27):
Fix SVG output with non-ASCII characters (the charset in the SVG file
is now set to UTF-8 not ISO-8859-1).
(Microsoft Windows version): Fix error dialog on startup in pre-built
version. Reported by Brian Clipstone.
Manual: Add link to TerrainData wiki page. Omission highlighted by Erin
Lynch and "detrito".
Fix to build without FFmpeg/libav and with older versions, broken by changes
in 1.2.28. Reported by James Begley.
Changes in 1.2.28 (2016-09-24):
Show the contents of the line after error and warning messages while
processing survey data, and indicate the region of the line in many cases
in the same style that compilers such as GCC and clang use (using the
column number we already have, plus new width information). Based on a
patch from Mateusz Golicz.
Add column and width information for many more error and warning messages.
Fix column for "Separator in survey name" warning.
Improve warnings when using a backclino with range 0-180 degrees (reusing
the same machinery we already have for a forward clino with range 0-180
Include LRUD in printout/export of extended elevations, broken by
improvements to export of tilted elevations in 1.2.27. Reported by Anthony
Name <trk> tags in GPX output, so Garmin GPS units name the imported track
usefully. Reported by Anthony Day.
Remember scale from previous print or export operation in the same run of
aven. Suggested by Stuart Bennett.
Convert range indication below shown line to a highlight on that region
of the line in cavern log window.
Fix colouring of error/warning without column in cavern log window.
Fix click on error/warning without column in cavern log window.
Fix highlight of translations of "error" or "warning" containing non-ASCII
characters. This fix for this only works with a Unicode build of
wxWidgets, but as of wxWidgets 3.0, all builds are Unicode, so this
shouldn't be much of a problem as wxWidgets 2.x is close to obsolete now.
Reported by Mateusz Golicz.
Disable selection of text in cavern log window - you can't currently copy
it to the clipboard, so until that's implemented it seems better to disable
the ability to select it. Reported by Wookey.
Avoid special "1000" scale entry when exporting.
Show 1 page when "One Page" selected.
Reload processed data when restricting view. Fixes failure when
restricting view on data just processed via aven. Spotted by Andrew
Atkinson and myself.
Don't hide blobs and crosses behind terrain. Reported by Jenny Black.
Fix rendering of crosses using point sprites. The texture being used was
misaligned relative to the image used for the visual fidelity check, so the
check always failed and point sprites would never be used. Where point
sprites are supported, they're probably the fastest option - on my netbook
this change improves FPS by ~6 fold when displaying crosses for a large
Support drawing blobs using point sprites. About 5 times faster than using
lines on my netbook.
Recheck how best to draw crosses and blobs on the first run after Survex
is upgraded (or downgraded) as the rendering code may have changed (we
already recheck when the OpenGL hardware or driver changes).
Change "MPEG" export to be MPEG4 (.mp4) rather than MPEG1 (.mpg).
MPEG4 produces smaller output of higher quality, and should be widely
supported these days. And I can't get the MPEG1 output to work without
buffer underflows, resulting in a file which doesn't play without
Add OGG video to the list of formats - it's more compact than the others
we currently list, though slower to write.
Fix export to movie formats for which libav/FFmpeg needs to seek the file
being written. This was broken by changes in 1.2.27.
Overhaul movie export for the current FFmpeg API, fixing deprecation
warnings when building against a recent version.
(Microsoft Windows version): Fix corrupted exported movie files. 1.2.27
changed the movie export code to allow writing to files with non-ASCII
characters in the names, but the new code failed to open the file in binary
mode, leading to corrupt output. Fixes #81, reported by Erin Lynch.
* (Microsoft Windows version): Pre-built version now uses FFmpeg 3.1.3 for
* (Mac OS X version): Pre-built version now uses FFmpeg 3.1.3 for movie
Fix to build without FFmpeg/libav, broken by changes in 1.2.27. Reported by
The Polish translation is now very close to being complete, thanks to a
substantial update from Mateusz Golicz.
Merge catalan translation updates from Adolfo Jayme.
(Microsoft Windows version): Map LANG_CHINESE to zh_CN not zh so Chinese
messages get used automatically.
cavern.tst: Remove random : from after ] - dash ignores the extra character,
but it causes this test to fail if /bin/sh is a different shell (e.g. bash).
cavern.tst: Add expected output for more testcases.
Remove unwanted execute bit from some testcase data.
Use https for more URLs which support it.
Changes in 1.2.27 (2016-06-06):
Right click on a survey in the survey tree now gives a pop-up menu
with "Hide others", which restricts the view to just that survey
and any subsurveys. Right click on the root of the survey tree
gives a menu with "Show all" to undo any restriction in effect.
(Currently these are implemented by reloading the file and using
the same machinery as the --survey= command line option, but that will
probably change in the future).
If there's a sub-survey restriction (from the --survey= command line
option or the new UI described above) it is now shown in brackets after
the survey tree root.
When reloading a survey, preserve the current view position (previously
the view was recentred).
When reloading a survey, actually preserve the current scale factor
(this was meant to happen, but the adjustment was applied in the
New "File->Extended Elevation..." menu item provides a way to generate
extended elevations for simple cases without having to use the command
line. Suggested by Fleur Loveridge.
Don't process key presses if accompanied by an unexpected modifier key.
In particular, this means that aven no longer interferes with Alt+<function
key> (which is typically handled by the desktop) and Alt+<letter> (which is
typically a menu short cut). Reported by Владимир Георгиев.
Reduce file loading time by ~5%. The station name compare function was
something of a hot spot, and optimising it yielded a nice improvement.
Allow splay legs to be disabled in when printing and exporting. Mostly
SVG export now shows splay legs thinner and in grey. See #60.
Fix export of rotated plans and tilted elevations - previously plans were
always aligned with North up, and elevations which weren't exactly side on
were exported as plans. Reported by Stuart Bennett.
Fix offset bounding box for exported elevations.
In print/export dialog the bearing value now wraps if you scroll up past
360 or down past 0.
Fix greying out of LRUD-based controls in the print/export dialog when the
view is tilted (i.e. not plan or elevation). This stopped working in
1.2.18 when the pan and tilt spin controls were changed from integer- to
Printouts now show LRUD as pale grey arrows from the station they are
measured from. Based on patch from Michael Sargent. Closes #65.
Take LRUD into account for printout size. Fixes #72, reported by Erin
Update movie export code to work with latest version of FFmpeg.
Make "Show Log" a toggle, so you can click on the button to take a look at
the log, and a second click returns you to the survey view.
(Microsoft Windows version): Open the font file in binary mode - it looks
like we were lucky and the font file (or at least its current version)
would have loaded OK in text mode despite being binary data.
(Microsoft Windows version): Exporting to files with non-ASCII filenames
should now work.
Allow tape or backtape to be omitted. Reported by Erin Lynch.
Grid convergence is now corrected for when using automatically
calculated declinations (*declination auto <X> <Y> <Z>). Requested
by Mateusz Golicz on the mailing list.
Clear any cached calculated declination upon another *declination auto
with different coordinates. Previously if the date stayed the same,
a previously cached declination for the old coordinates was used.
Fix check for end of version number array in *required. We would check up
to 12 version components, the last 9 being bogus. In practice, *require is
only likely to be used with up to three components, so this wouldn't be an
*begin with an invalid prefix could cause a crash in some cases. Fixed
by patch from Colin Watson.
Report column locations for errors to do with readings.
Merge translation updates from Jean-Marc.
img library: Better document which members can be set when writing.
Highlighted by email query about use of img API from Владимир Георгиев.
Document how *declination interacts with *calibrate declination if both are
used in the same dataset.
doc/3dformat.htm: Update details of how changes to the current label buffer
are encoded to reflect changes in v8. Reported by Angus Sawyer.
Use docbook2man instead of docbook-to-man to generated Unix man pages
from SGML source. The latter seems to be no longer actively maintained, and
docbook2man now does a similarly good job.
Use https for survex.com links, and for other sites which support it.
Changes in 1.2.26 (2016-01-07):
(Microsoft Windows version): Simplify upgrading process with innosetup
installer - if Survex is already installed, we now just install to the same
location and use the same start menu folder.
(Linux version): survex.spec: Update for filetype metadata change in 1.2.25.
Fixes #79, reported by James Begley.
(Linux version): survex.spec: Fix to work with RPM 4.13. Fixes #79, reported
by James Begley.
Changes in 1.2.25 (2016-01-05):
Drop broken code which attempts to fix 2D pitches. Fixes #73, reported by
Erin Lynch. #76 tracks the issue the removed code was trying (but failing)
When animating, don't try to update station info based on mouse movement
over the survey tree.
Further improve code to handle cavern subprocess in aven.
Fix jump to error for filenames containing colons when the error location
doesn't have a column number. Bug noted by Jenny Black.
If we encounter bad UTF-8 in cavern output, replace it with a red and white
? in a diamond (previously we gave up showing output at the first bad
sequence). This can happen if you process a .svx file which isn't UTF-8
(Unix version): Don't try to set the terminal window title when opening an
editor from the cavern log window - gnome-terminal no longer supports this,
and there doesn't seem to be a portable option for specifying the title for
terminals which do still support this.
(Microsoft Windows version): Also quote for cmd.exe so that paths with
spaces in work reliably. Reported by Marco Cotto.
Improve error for mismatched fore/back-sight plumbs, reported by Andy
Edwards (see #78).
Fix to use correct sd for backcompass. We were using zero instead, the
most obvious effect of which was that the threshold for warning about
differing COMPASS and BACKCOMPASS was about 71% of what it should have
been, so we were warning in more cases than we should have been.
Implement support for specifying a length on backsights - if you're using
something like a disto-x, you'll get a distance reading for the backsight
too. Fixes #71, reported by Erin Lynch.
Make line counting more robust to mixed line ends. Noticed in example file
from Pete Smart (see #69).
extend: New --show-breaks option which adds a leg flagged as surface survey
between each points at which a loop has been broken. Suggested by Jenny
(Unix version): Update filetype metadata to work with modern desktops.
Fix incorrect reporting of errors reading and writing processed survey data.
Since 1.2.8, the error strings corresponding to IMG_CANTOPENOUT,
IMG_BADFORMAT and IMG_DIRECTORY have been mixed up (this doesn't affect
external programs using the img library, only Survex). Reported by Jenny
Add missing options to extend man page and --help output. Noted by Jenny
Document Document Ctrl+cursor keys for rotating and tilting in aven man page.
Fix broken SGML markup in manual.
Fix typo in manual reported by Jenny Black.
Update vim syntax file for newer commands, etc.
Minor translation updates. Thanks to Piotr Strębski and Jean-Marc.
Fix to compile with FFmpeg 2.9. Reported by Andreas Cadhalpun in
Stop maintaining ChangeLog files. They make merging patches harder, and stop
'git cherry-pick' from working as it should. The git repo history should be
sufficient for complying with GPLv2 2(a).
(Microsoft Windows version): The installer requires admin privileges on Vista
and later and OS versions older than Vista are past end of life, so drop code
which tries to set up the registry differently depending if we have admin
privileges or not.
Changes in 1.2.24 (2015-09-23):
(Microsoft Windows version): Fix the cavern log window. Reported by Brian
(Microsoft Windows version): Add workaround to avoid breakage in Therion.
Reported by Jenny Black.
If wx was built with thread support, aven now runs cavern from a separate
thread, which works much better under wxMSW (where we can't use select),
and also seems a bit smoother on Linux.
Fix handling of encoding of filenames when the operating system has no
locale installed corresponding to the language selected for Survex's
Undo accidentally committed debugging code which was sending message to
the terminal in 1.2.23.
(Linux version): configure now looks first for wx-config-3.0, which Fedora's
wx3 packages have. Reported by James Begley.
Indonesian translation fully up to date again.
Manual: Document anonymous stations, based on the text from NEWS. Reported
Changes in 1.2.23 (2015-09-06):
Updating the cavern log window is now much smoother, especially on slower
Show "busy" mouse cursor while processing survey data.
Fix an assertion if you try to start processing a survex file while one is
already being processed.
Processing a .svx file with an error now still adds it to the file history.
Reported by Martin Green.
Fix the orientation of the starting end of tubes.
New *ref command to allow specifying an external reference (e.g. where to
find the original survey notes).
Drop support for showing percentage progress in cavern. It's confusing in
a multiple-file dataset as it shows progress in the current file so jumps
around. It also slows down processing, and on a slow machine you'd don't
want that, while on a fast machine processing isn't slow enough for the
progress display to be useful.
French translation is now completely up to date, thanks to Michel Bovey.
Bundle proj's EPSG and ESRI code lists in the installers for MS Windows and
OS X so that things like "*cs EPSG:29903" work. Reported by Graham Mullan.
(Microsoft Windows version): Process survey data with aven rather than
(Microsoft Windows version): Installer built with InnoSetup 5.5.6 (recent
releases have been built with 5.5.3) to see if that solves Ray Duffy's
reported issue with not having file associations for .svx files created.
Changes in 1.2.22 (2015-08-17):
Ensure that the window has a depth buffer. Whether it does by default
seems to vary depending on OS and maybe graphics card. Fixes #55 (terrain
is no longer visible through itself), and also the rendering of passage
tubes. Thanks to Martin Green for pointing me in the right direction for
finding this fix.
Fix *declination with an angle to actually work.
Fix assertion if we try to identify a hanging survey by an anonymous
Improve errors for invalid survey names in *begin, *end, *equate and
Changes in 1.2.21 (2015-07-28):
Fix exporting to KML and other text-based formats to always use "." for the
decimal separator - previously "," would be used when the user's locale
specified this for the decimal separator. Reported by Jan Schorn.
Implement exporting of survey legs in KML format.
Put "paddle" placemarker icons on stations in exported KML files, using the
same colour coding for entrances, fixed points and exported points as aven
Remove the "Coordinate projection" field from the print dialog, as it isn't
relevant there. Reported by Wookey.
Fix the initial scale for small caves (since 1.2.18 the initial scale has
been too small). Reported by Wookey.
Don't rescale if the same file is reloaded, but adjust the volume diameter
Use wxGetenv() to read the SURVEXEDITOR variable, so we can accept Unicode
values on Windows.
Fix coordinate systems using latitude and longitude - PROJ.4 wants these in
radians, but we were passing degrees, which would generally cause the
conversion to the output coordinate system to fail. Reported by Wookey.
Fix *fix with standard deviations when *cs is in use, give an error for use
of *fix with standard deviations before *cs.
Add new *declination command with support for setting the declination
automatically from the IGRF model based on the survey date. Thanks to the
Therion developers for the IGRF support code, which we're reusing.
Fixes #54, reported by Wookey.
Allow the units for the zero error to be specified, making it easier to
specify calibration with a scale if you measure the zero error externally
(rather than using the instrument itself). Fixes #61, reported by Andrew
Report the error from PROJ when coordinate conversion fails as part of the
actual error rather than on a separate line.
Fix use after free after *solve. This only occurs if a leg between the two
exact same stations appears right before and right after the *solve, which
is unlikely in real data, but the testsuite has an instance of this. This
was introduced by the repeat leg averaging added in 1.2.17.
Fix small memory leak when solving network. This doesn't really matter
when solving at the end of processing as cavern will exit after that, but
if *solve is used we continue processing after solving.
Remove compatibility handling for specifying a country variant of a language
in SURVEXLANG using "-" with a lower case country code (e.g. "en-us") - we
changed to the standard "en_US" way back in 2001. This code was mangling
character sets with a "-" in, and is no longer useful.
Ignore any "@<something>" modifier in the language code.
Improve documentation of magnetic declination handling, and cover the new
Document aven's command line options in the manual and its man page.
Reported by Jenny Black.
Point to '*case' and '*truncate' from the 'SEE ALSO' sections of each other's
Remove references to SpeleoGen from the documentation - it hasn't been
updated for many years, and can't read recent versions of the .3d format.
Strip documentation references to obsolete versions of MS Windows.
doc/HACKING.htm: Update list of debian packages to install to build from git.
Changes in 1.2.20 (2015-06-26):
When printing, use the top margin rather than the right margin to calculate
the height of the printable area. In practice, the two values seem to be
the same or very similar by default.
Avoid assertion if the about dialog image fails to load. Reported by Phil
Optimise the size of the about dialog images.
Add support for reading terrain data which isn't in a .zip file.
Force a refresh after loading terrain data so that it gets displayed right
Make checks for terrain data extensions in zip files case insensitive.
If reading terrain data fails, always report an error and never try to
cavern: Allow clino readings in diving style data, suggested by Andrew
Atkinson. Currently these readings are ignored, but a future version will
check that they're consistent with the angle given by the depth gauge and
tape, and perform suitable averaging.
Remove lingering traces of svxedit.
configure: Fix to allow compiling without libav/ffmpeg, as was possible
(Unix version): Install the filetype and aven application icons under
/usr/share/icons/hicolor, which is where they're expected to be these days.
(Unix version): Add %f to Exec in survex-aven.desktop.
(Mac OS X version): Remove useless extra copy of about box images from OS X
(Mac OS X version): Only ship one copy of each of the translations.
(Mac OS X version): Reduce the size of the aven binary by disabling a load of
libav features we don't use.
(Microsoft Windows version): Reduce the size of the aven binary by disabling
a load of libav features we don't use.
(Microsoft Windows version): Update message files to fix a missing Chinese
message in the installer.
Changes in 1.2.19 (2015-06-18):
Fix exporting to GPX, KML and HPGL, which all failed to write the header to
the exported file in 1.2.18.
Add exporting to Survex .pos format.
If the measuring line isn't currently active, pressing "Escape" will now
exit full screen mode.
(Mac OS X version): Change the shortcut for full screen mode to be the
standard Ctrl+Command+F (rather than Shift+Command+F which we have been
using since 1.2.7).
(Mac OS X version): When we centre the view on the station this can
generate a mouse move event, so clear the variable which says we are
dragging before we process a left click on a station. This avoids random
rotations of the survey when clicking on a station, reported in #47 by Hugh
(Mac OS X version): Force use of a non-native toolbar to stop the toolbar
icons from being rescaled and looking fuzzy.
(Mac OS X version): Remove code added in 1.2.18 which tries to set stop the
toolbar icons from being rescaled, but which requires an unreleased version
of wxWidgets, had a typo in, and doesn't actually seem to work anyway.
(Mac OS X version): Drop out of full screen mode if the mouse is mode to
the top of the screen, since we can't seem to display the menu bar in this
case like we do on other platforms.
(Mac OS X version): Enable aven's movie export feature.
(Mac OS X version): Enable wxDisplay when building wxWidgets to better
support multi-monitor setups.
(Mac OS X version): Silence warning visible when aven is run from a
terminal about a missing CFBundleTypeRole.
When reading terrain data from a .zip file, report an error if the .zip
file is bad, or if it doesn't contain any terrain data we recognise.
Tweak error message in terrain reading code to distinguish two failure
Add viewing angles and scale to footer, and shorten some of the other items
to make room for this extra information. (Fixes ticket #52, reported by
If the footer is wider than the printout width, scale down the font used
so that it exactly fits; if the footer is narrower, than space out the
items in in so it uses the full width.
If the saved size for aven's window exceeds the current display size
(mostly likely because we're now plugged into a smaller monitor), then
reduce the size of the window to fit the display. If the saved size is <
(480x320), increase it to at least that, as aven isn't usable in a smaller
Remove crude bodge which tries to pick a nicer initial window size when
using wxWidgets without wxDisplay on a multi-monitor setup - aven now opens
with the same size window it had when it was closed, so the initial size is
only relevant on the first ever run.
Assorted translation updates. Notably Indonesian is at 100% again.
Stop trying to catch and report signals. The only real reason to do it is so
we can say "Bug in program detected! Please report this to the authors"
before we exit, but when the program crashes that's pretty obvious. In aven
we try to pop up a message box for this message, which may fail due to
whatever caused the signal, while with the command line tools there's no
great benefit over just letting the shell report the signal.
Use pkg-config to probe for libav and proj, which sorts out the correct flags
for building on OS X against a static install of libav.
Changes in 1.2.18 (2015-06-03):
Add support for reading terrain data (from a zip file containing either an
SRTM .hgt file, or an ESRI .bil file and associated metadata files), and
rendering it as a transparent surface.
Remove actions from 'Orientation' and 'Rotation' menus which you wouldn't
sanely want to perform from the menu.
Create a "Colour by" submenu of the "View" menu to house the various
Add "Colour by Gradient" and "Colour by Length".
Make the button to dismiss the "About" dialog "OK" rather than "Close",
which seems more logical, and also allows the dialog to be closed by
Destroy any existing clipping region before we write the page footer.
Hopefully solves ticket #52, reported by Erin Lynch.
Don't round bearing and tilt angles to integers when printing and
Add passage export for EPS format. (Partly addresses ticket #4)
Add JSON export. This should be regarded as experimental, and the format
is quite likely to change.
Pressing F6 now toggles the display of rendering stats, currently FPS
(Frames Per Second) and the number of triangles in the terrain mesh.
Add a menu item and toolbar button to show the cavern log window if the
currently shown survey data was processed by aven. Reported by Hugh St
Lawrence in #47, and by Dave Clucas and others previously on the list.
Add "Save Log" button to Aven's cavern log window.
In cavern log window, highlight "error" markers in red and "warning"
markers in orange.
Rework code to read cavern's output. In particular, we no longer mix
buffered and non-buffered system calls.
Aven's support for reading colours and font sizes for printouts from
print.ini has never worked - the contents of the ini files are ignored due
to a bug which has been there since the code was added in 2005 - but nobody
has ever complained. So just strip out that code entirely - we should
support setting the colours and font sizes, but a GUI interface for setting
them would be better.
Fix to compile with a Unicode build of wxWidgets 2.8. Reported by Bill
Take the width of the messages used above the compass and clino into
account when calculating how much space to allow for them - now the labels
won't overlap or be cut off in translations where they are long.
(Mac OS X version): Attempt to address the size of the toolbar icons.
Reject *fix with SDs which aren't all positive. (fixes#2, reported by
Use the currently set units when outputting measurements in warnings,
errors, and the stats at the end of the run. Requested by Bill Gee.
Include column number when a *include file isn't found.
Show 'error' in front of error messages, like we show 'warning' in front of
warnings. Fixes #48, reported by Wookey.
Increase the threshold for warning that fore and back measurements differ
from 2 SDs to 3 SDs.
findentrances: If the 3d file specifies the coordinate system, use it.
svxedit: Remove svxedit - while an editor with built-in knowledge of survex
would be nice to have, svxedit doesn't really offer that, and it looks ugly
in a modern desktop.
If we run out of memory while reading a processed survey data file, include
the filename in the error message.
Many translation updates - notably Indonesian and Russian are now the two
most complete translations.
(Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
Transliterate gradient and infinity symbols if the current character set
Add SVG version of .plt icon.
Add complete list of quantities you can set SDs for. Thanks for Wookey for
highlighting that the previous list was incomplete.
Document averaging of a group of repeated readings.
Add a link to the sample data from the manual.
Remove references to contact addresses which are no longer there. Remove
offer to post people floppies, and references to a CD image which isn't
available for download.
Remove non-breaking spaces from the diffpos and extend manual pages, as they
actually make the output formatting worse (presumably these used to work
around a since-fixed bug in one of the docbook processing tools).
Fix to compile without warnings with 'g++ --std=gnu++11'.
Changes in 1.2.17 (2015-02-24):
MacOS X version:
Update INSTALL file with current status.
Aven.app now has a custom icon.
Add icons for all the filetypes supported.
Add Finder actions for .svx, .3d, .plt and .pos files.
aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
currently do this for us.
aven: Fix short-cut for toggling Full Screen mode.
aven: Make "About" menu item appear.
aven: Fix "Close" button in about dialog.
aven: Make custom cursors black with a white outline to match the standard
OS X cursor.
svxedit: Now wrapped up in an application bundle as svxedit.app. It
still doesn't really work like a standard app though - e.g. you can't load
files from Finder (instead run svxedit.app and use File->Open), the font
size of most menu items is wrong, the icon for the app is the wish icon
rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
probably more. I'd probably recommend using another editor (OS X comes
with TextEdit.app for example).
The documentation is now in a "Docs" directory alongside the apps, rather
than in the rather less obvious "share/doc/survex" directory.
Default to building for x86_64, since all modern Macs are 64 bit.
Disable use of liblzma when building wxWidgets for OS X, which was
preventing the build from working on OS X 10.6.8.
Download wx sources from SF via redirecting link. Thanks to David A.
buildmacosx.sh: Handle the mount point for the disk image containing a
Link with a static build of PROJ for doing coordinate system conversions.
Build wx with --disable-webview to avoid a compilation failure on OS X
Use wx-config --cc and --cxx to get the compilers to use for building
everything else, as wx adds options to them which otherwise cause linking
The diskimage (.dmg) file is now compressed with bzip2, which gives a
smaller download. This means OS X 10.4 is required, but we probably
already need at least 10.5 because that's the minimum version which the
wxWidgets build supports by default.
Remove unused files and copies of files from the diskimage.
cavern: If the same leg is repeated consecutively, average the readings and
treat as a single leg.
dump3d: Report SEPARATOR used by the file being read.
aven.svg: Fix visual glitch in SVG icon for aven. Noted by David A. Riggs.
Greatly reduce flicker when mouse is moved to the top of the screen in full
screen mode and the menu bar reappears.
For export formats where scaling is supporting, aven now actually uses the
scale specified in the export dialog (previously it ignored this and used
Reimplement animation so that it's based on angular change per unit of
elapsed time, rather than averaging the time take for the last two scene
redraws. This gives smoother animation in the face of variable load and
scene redraw time, and should be more consistent between platforms.
Switching to a point of the compass during auto-rotation now jumps straight
there rather than the two animations fighting.
Reduce the maximum auto-rotation speed, as the previous limit was uselessly
Disable stepping the rotation angle when animating (previously we only did
Speed up start-up a bit - rather than loading icons from individual PNG
files on disk, compile them into the aven binary.
(Unix version): Add "MimeType" field to desktop files so that file
associations work out of the box with modern desktop environments.
Add start of Hungarian translation from Imre Balogh.
Merge in many updates to the Russian translation from "vsuhachev".
Assorted minor updates to other translations.
Create scalable (SVG) versions of file type icons.
doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
we're using git.
tests/: Improve test coverage in a few places:
Extend tests of fore and back sights to test calibration of the back
Test "Can't calibrate angular and length quantities together" error.
Check that "*set names ." works when "." is also the decimal point.
Changes in 1.2.16 (2014-10-17):
aven: Add KML export (stations only currently).
aven: Allow measuring line to measure from anonymous stations. (Fixes #44)
aven: Fix corrupted names in exported files.
aven: Fix error log window under wxWidgets >= 2.9 to include the system
information before the first log message like it does under wxWidgets 2.8.
cavern: Add support for "*cs JTSK" and "*cs JTSK03".
tests/: Improve test coverage.
Translation updates for many languages, plus the start of translations to
Greek and Polish.
Fix to build against wxWidgets 3.0 built with assertions disabled. Reported
by Martin Sluka.
Fix warnings when compiling with clang (which is the default compiler on
Mac OS X). Reported by Martin Sluka.
Changes in 1.2.15 (2014-08-14):
cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03". This
means that we now support all the coordinates systems which Therion does,
except for a few which don't have X=East and Y=North. The documentation
for *cs has also been improved.
aven: We no longer persist full screen mode between runs - it's not a
standard behaviour of desktop programs, and it's too easy to go into full
screen mode from the menu and then not be able to get out again because you
don't know the required key shortcut. (ticket#39)
aven: When in full screen mode, moving the mouse to the top of the screen now
makes the menu bar appear. This provides a non-shortcut way out of full
screen mode, as well as making it easier to perform other operations while in
full screen mode. The current implementation gives an annoyingly flickery
transition, but hopefully we can improve this in future. (ticket#39)
(MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
development), we now call EnableFullScreenView() which improves the full
screen mode experience on OS X 10.7 and later.
img library: Improve documentation for img_ERROR_INFO.
tests/: Ship some missing .out files and compare.tst.
tests/: cavern.tst testcase back2 is now actually used. Fix a bug in this
testcase, and extend it to cover a variant of the situation reported as a bug
in therion by Bill Gee to the therion list.
(Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
for the survex package and on tk for the svxedit package.
Changes in 1.2.14 (2014-07-05):
img library: Add ability to store a PROJ4 string describing the coordinate
system in use in 3d v8 files.
aven: If the 3d file specifies a coordinate system, then use it for exporting
to formats which need to know (currently GPX). If the input file doesn't
specify the coordinate system, allow the user to enter a PROJ4 string in the
aven: You can now quickly zoom to a particular area by holding down the
"Shift" key and dragging with the left mouse button to create a rectangular
"rubber band box" around the area you wish to zoom to. If you release the
"Shift" key while still dragging, the box is centred on the start point
rather than having one corner there.
aven: Fix exporting of passage tubes in elevations and extended elevations
- previously up and down were getting drawn across the page!
aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
1.2.13. (Reported by Brian Clipstone)
aven: Fix the conditions on which the menu item "Cancel measuring line" is
enabled - previously it was hard to actually cancel it via the menu.
Reported by Hugh St Lawrence.
aven: Fix wx assertion failures when showing hit test debug view on platforms
such as 64-bit Linux.
aven: When viewing from above, show "Plan" above the "clino" which indicates
the tilt angle (instead of "Elevation -90°").
aven: The extended font data now loads faster, and also uses less memory on
aven: Dragging the vertical divider between the side panel and the 3D view
now only updates when you finish the drag, as redrawing continuously just
looks clunky except on an ultra-fast machine.
aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
the space available in the aven UI.
cavern: Add a *cs command to allow setting the coordinate system for *fix
commands, and the coordinate system used for processed survey data. The
latter is now stored in 3d v8 format files.
cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
and handle it in the same way as the "DUPLICATE" flag in .svx files.
cavern: If there's more than one *fix command with coordinates, still
actually fix the second and subsequent ones, to avoid triggering bogus errors
about unconnected surveys.
cavern: If there's more than one *fix command with coordinates, report the
station name of the previous one, plus the file and line number where it was.
cavern: Fix handling of the rather contrived case of *fix with no coordinates
followed by *solve and then another *fix with no coordinates not to access
dump3d: Report any specified coordinate system.
doc/3dformat.htm: Update to document how the coordinate system is stored.
(Microsoft Windows version): Include dump3d in the installer.
Fix a compiler warning.
Improve test coverage.
Changes in 1.2.13 (2014-05-15):
aven: Fix --print option to wait for printing to happen before exiting
(previously it would exit right after opening the print dialog, so you
couldn't actually print anything out using it).
aven: Increase the threshold for how close the pointer needs to be to a
station from 5 pixels to 7 to try to help touchscreen users. Reported by
Hugh St Lawrence.
aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
if increasing the minimum pointer to station threshold helps Hugh's problems
with using aven on a touch screen device.
aven: The measuring line was unable to see stations which had just been
revealed by toggling surface or underground legs on - this is now fixed.
aven: Add "hit test grid debug" mode, which shows the hit test grid and how
many entries are in each box (toggled by F3).
aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
off and back on.
aven: Create the empty hit-test grid data structure lazily, to reduce start
up time a little.
cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
and *end commands to instead talk about "survey names".
cavern: For ages cavern has warned if you reentered a survey, but this
warning was suppressed if it occurred at the same line of the same file as
the survey was first entered, but this can only happen if you include the
same survey file more than once, which isn't a sensible thing to do for a
file with actual survey data in (you might reasonably do it to set up survey
grade details or something like that). The warning is now given in this
cavern: After 5 warnings about reentering a survey we give up warning about
it, but we used to keep reporting where the survey was originally entered -
this secondary diagnostic message is now silenced when the main message is.
(Microsoft Windows version): Compile C code with optimisation on.
Add the start of a Russian translation, with messages take from therion.
Minor translation updates to French.
Fix compiler warning from GCC.
Test that "..." anon station works.
cavern.tst: Check number of errors returned by all testcases which should
fail and give an error count.
cavern.tst: Fix to actually fully test everything when builddir != srcdir.
Changes in 1.2.12 (2014-04-14):
aven: Fix measuring line to show change in altitude rather than altitude
itself (accidentally broken by changes in 1.2.11). Reported by Brian
aven: Fix printing when built with wxWidgets 3.0.
aven: Several visual improvements to printouts:
Move the numbers below the scale bar down a little so that they don't
overlap the scale bar ticks.
Set the clipping region after we draw the page border and info box to avoid
clipping the border in print preview.
Tidy up the appearance of the compass and elevation arrow.
aven: Fix to build with libav 10. Reported by Moritz Muehlenhoff in
aven: Fix to build with older libav where avcodec_free_frame() isn't
(Linux version) survex.spec: Update spec file used for building RPM packages.
(Unix version): Add "Keywords:" entry to .desktop files.
(Unix version): Enable large file support, mostly to support filing systems
which return 64 bit inode values, such as CIFS mounts.
(Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
rather than any character which is a letter in the current locale.
Various translation updates.
Changes in 1.2.11 (2014-01-28):
aven: Fix wxWidgets assertion when double clicking on an anonymous station.
Reported by Kevin Dixon.
aven: Embed the font data for the first 256 Unicode characters for use in the
survey pane into the compiled aven binary to reduce start up overhead. Any
additional characters needed are loaded from a data file only if/when a
character >= U+100 is actually needed (as before).
aven: Fix display of Unicode characters above 256 when there's a character
<= 256 earlier in the same string.
aven: Use the actual width of Unicode characters above 256 rather than
assuming they are 16 pixels wide.
aven: If full screen, don't show the side panel when a new file is opened
(e.g. via Ctrl+O).
aven: Don't give an assertion failure when showing passages for a cave with
no vertical extent. Reported by Jonny Prouty.
aven: Change terminology in print dialog - say "legend" instead of "info
aven: Add option to show the tilt angle as a percentage gradient.
aven: Show the units (degrees, grads, or percent) for the tilt and bearing
aven: All length units are now translatable.
aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
will reduce code size and also the number of deprecation warnings about
gluErrorString on Mac OS X 10.9.
(Microsoft Windows version): aven: Try to work around redraw issues related
to the measuring line by redrawing the whole window, which doesn't seem to be
cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
give an error rather than quietly ignoring the attempt.
cad3d: Make cad3d remap control characters and spaces in station names when
generating PLT output in the same way aven does.
Various translation updates (particular thanks to Eric Madelaine and Dennis
Baudys), including the start of a Bulgarian translation, with messages taken
from Therion and elsewhere.
(Microsoft Windows version): On Microsoft Windows 2000 and newer, use
GetUserDefaultUILanguage() to get the UI language to use. For older
versions, continue to use GetUserDefaultLCID().
(Microsoft Windows version): The Indonesian translation will now be used
automatically when the system language is set to Indonesian.
(Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9. Thanks to David
A. Riggs for his work on this.
(Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
checksum check for the downloaded wx sources.
Fix a lot of the compiler warnings when building with clang.
doc/manual.sgml: Add missing quantities to the list documented as accepted by
*units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
mentioned in list of the units that can be set for them); COUNT (missing
alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
(incorrectly listed as X, Y, Z). Reported by Jonny Prouty.
Test suite: Improve test coverage for cavern.
Changes in 1.2.10 (2014-01-15):
aven: Fix assertion if two mouse buttons are held down at the same time.
If dragging with more than one mouse button held down, releasing one causes
another which is still held down to take effect. Reported by Brian
aven: If we fail to start the external editor when the user clicks on an
error or warning from cavern, show an error box.
aven: If the survey has a title, add it as a top-level <title> element to
exported SVG files.
aven: Escape '<', '>', and '&' in labels in exported SVG files.
aven: In GPX export, set the <time> element to the datestamp from the 3d
aven: Don't try to write the title if it isn't set or is empty when exporting
aven: Don't bother looking up the printer page setup info when exporting.
(Microsoft Windows version): aven: Fix crash on "File->Print" or
"File->Export" under Windows XP, reported by Brian Clipstone.
(Microsoft Windows version): aven: Fix error dialog about an incorrectly
encoded filename which could occur if run without being asked to load a file
(Microsoft Windows version): aven: Compile with optimisation on.
img library, aven: Although processed CMAP data files are often referred to
as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
and .ADJ (adjusted) extensions are. Since we've long checked for .XYZ, we
continue to do so in case anyone is relying on it, but also check for the
img library: Add new "datestamp_numeric" field to struct img giving the
datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
failed to convert it). For .3d >= v8, this field is reliable. We attempt to
convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
img library: Fix my_strcasecmp() to handle top-bit set characters better.
cavern: Fix NULL pointer dereference when processing Compass DAT file without
doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
doc/manual.sgml: Note the station length limit Smaps used.
Fix some compiler warnings if built with glibc's fortify source feature
Changes in 1.2.9 (2014-01-08):
Document --3d-version in cavern man page and the manual.
aven: Fix compilation error in movie export code with recent libavi.
aven: Fix warning on stderr when export a movie as MPEG.
img library: In non-hosted mode, don't define GETC and PUTC if they're
already defined, to allow easy overriding with getc_unlocked() and
putc_unlocked() (which are significantly faster on Linux).
img library: In non-hosted mode, check that int is at least 32 bits,
and if not, use long. In practice, platforms with 16 bit int are mostly
obsolete, but it's not hard to be portable here.
img library: Add test that img.c and img.h compile in non-hosted mode
(regression test for issue fixed in 1.2.8).
(Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
Update translations from launchpad and from existing similar messages.
Fix some compiler warnings.
Changes in 1.2.8 (2013-10-29):
cavern: Fix handling of anonymous wall stations ('..' by default) to
implicitly set the SPLAY leg flag, as was intended. Reported by Thomas
cavern: Tweak .err file output not to lose the space in front of certain
statistics when the value gets large.
cavern: Eliminate redundant progress message when solving simultaneous
aven: Add a format drop down to the export dialog, and only show fields which
are meaningful and supported for the currently selected export format. The
format defaults to that used most recently. The "Elements" and "View" boxes
have been swapped in the print and export dialogs as that layout works much
better when the "View" box is hidden.
aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
- now works again. Reported by Anthony Day.
aven: Add GPX export (based on findentrances patch from Olaf Kähler). In
this release the projection which the survey coordinates are in defaults
to the BMN M31 grid used in the Totes Gebirge in Austria. On Unix, you
can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
projection string. The ability to specify this projection in a better
way is coming soon.
aven: New export options "Origin in centre" and "Full coordinates" - the
latter fixes #10. GPX and PLT output implicitly force "full coordinates".
aven: The "Sketch" vector drawing program got renamed to "Skencil" some
time ago, so update references.
aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
with wxMSW 2.9.5. Reported by Brian Clipstone.
aven: Make right click in an empty presentation mark the current position and
open it to edit, instead of crashing.
aven: Update movie export code to work with latest libav API. Reported by
aven: Improve reporting of errors during the process of exporting a movie.
aven: Don't try to close the movie if we aren't producing one.
aven: Fix assertion failure when double-clicking on the survey with wx2.9.
aven: Fix to build with wxMSW 2.9.5.
aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
ago, so add a new --skencil option to specify this output format. The old
name (--sketch) is still recognised for compatibility.
cad3d: Make --marker-size work for Skencil and SVG output.
dump3d: Make --show-dates option show dates for XSECT.
Fix to work once more when used outside of Survex (missing definition of
max() macro and a bad call to free() in img_close() for a file opened for
Use lround() instead of round(), and make the tests around whether we use
the library function or the our fallback implementation saner.
Fix // comments in C code for portability to pre-C99 compilers which don't
support these as an extension.
Can now be compiled as C++ as well as as C.
(Microsoft Windows version): The installer is now built with a newer version
of Innosetup, and includes translations for all the languages which Survex
itself has any translations for.
(Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
Minor translation updates.
tests/Makefile.am: Distribute files for "normal_bad" testcase.
Changes in 1.2.7 (2013-07-27):
Add support for anonymous stations, which are indicated by one, two or three
separator characters - with the default separator of '.', that means '.',
'..', and '...' are anonymous stations. Single separator ('.' by default)
is an anonymous non-wall point, double separator ('..' by default)
is an anoymous wall point at the end of an implicit splay), and triple
separator ('...' by default) is an anoymous point (with nothing special about
the leg). A new *alias command allows '-' to be mapped to '..' for
compatibility with pocket topo: *alias station - ..
New version 8 of the 3d format:
Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
New explicit file-wide flag for 'this is an extended elevation', rather
than modifying the survey title to indicate this.
The survey prefix is often unchanged from one leg to the next, so use a
spare flag to compactly indicate when there's no label change.
The data style of each leg is now stored.
The "processed at" time is stored as seconds since 1970 rather than a
Since 3d v8 features significant changes to the format, the format
documentation for v7 and earlier has been split off into 3dformat-old.htm.
New station flags img_SFLAG_ANON and img_SFLAG_WALL.
Handle .pos files containing unnamed stations - don't suck the next line in
as the station name, and set img_SFLAG_ANON for them.
Repurpose the long unused fBinary parameter to img_open_write() as a flags
parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
elevation, in place of appending " (extended)" to the title. Internally we
still append this to the title (and remove it upon reading) when writing
3d v7 or earlier, but for the new 3d v8 format, this flag is stored
explicitly in the file.
img.h: Add comments for the lists of "Leg flags" and "Station flags".
We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
now, and the wx developers consider even 2.8 to be rather long in the
tooth. We stopped testing building with wxWidgets 2.6 some time ago, and
formally dropping support for older versions allows a number of workarounds
to be removed from the aven source code. Also, features deprecated in
wxWidgets 2.9 are no longer used in our code.
Don't run incremental search on every key-press, as on a slow machine the
short initial search(es) will take a while but not be useful. Instead only
actually run the search when we're told there are no more key-presses
Implement support for including cross-section information in exported SVG
and DXF files (ticket#4). The DXF export is untested currently.
Show splay legs faded by default, with menu options to hide them or show
them like other legs.
Speed up loading a .3d file with cross-sections by using a map to convert
station names to positions.
In the cavern log window, don't highlight a file:linenumber if there's no
message after it, which avoids highlighting the "Included from" lines
Fix not to crash when trying to report an error while starting up.
(MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
the OS X standard shortcut Shift-Command-F (previously we used F11, but
that's used by the desktop).
Add checks for errors when reading the font file.
Remove useless extra quoting when invoking vim to show the location of an
error from cavern.
Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
Use wxValidator to simplify keeping svxPrintDlg member variables and fields
in the dialog in sync.
Demote errors about invalid dates to warnings, since we've accepted *date
for ages without any checks on the value, and so existing datasets
probably contain invalid dates and dates in other formats. (ticket#19)
New *alias command allows '-' to be mapped to '..' for compatibility with
pocket topo: *alias station - ..
We want to warn if there's a clino reading which it would be impossible to
have read from the instrument (e.g. on a -90 to 90 degree scale you can't
read "93" (it's probably a typo e.g. for "39"). However, the gradient
reading from a topofil is typically in the range 0 to 180, with 90 being
horizontal. Really we should allow the valid range to be explicitly
specified, but for now we infer it from the zero error - if this is within
45 degrees of 90 then we assume the instrument can read between 0 and 180
If the survey isn't all connected, still run survey tree checks and report
errors and/or warnings which might suggest typo locations. Thanks to Kevin
Dixon for the report which highlighted this issue.
Report a warning if *begin SURVEY has a separator character in SURVEY.
Report column numbers as well as line numbers for some cavern errors and
Adjust width of node stats table to fit longest count when there are more
than 9999 of a particular order of node.
If the argument to *include has an opening double quote but the closing
double quote is missing, then skip trying to open the file.
Move "Station X referred to just once" warning after non-existent survey
check - if both fire, the non-existent survey error is likely to be more
We no longer follow an error for a bad reading in passage data with a bogus
"End of line not blank" error, but instead check the remaining readings on
the same line.
We no longer follow an error about OMIT for a required reading with a bogus
"End of line not blank" error.
Report an error if the scale factor in *calibrate is zero - it doesn't make
sense and probably means someone reversed the arguments to *calibrate.
Report the parent include files starting from the outermost, as that's more
logical when there are multiple levels involved.
If we were expecting a numeric field and instead get something which starts
with '+', '-', or '.' but which isn't a number, then fix the error to
include that character in the token reported.
Simplify handling of quantity lists to only recognise 'DEFAULT' as the
cad3d: Check for errors from img_rewind() and report them.
Build, install and package dump3d as standard - it's useful for grabbing
info from 3d files in scripts.
Add --show-dates option.
Show only 2 decimal places on coordinates and passage dimensions.
Report the data style of legs.
Report if the file is an extended elevation.
Report img_STOP as STOP rather than CODE_0xffffffff.
cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
expected output so it passes reliably.
cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
'Deleted' stations upon failure are the more natural way round.
Add more testcases, expand some existing testcases, and add expected output
(Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
appropriate C and C++ compilers to use, and link mingw build statically to
avoid needing the libgcc DLL (which newer GCC seems to have by default).
(Unix version): When determining the character set for command-line tools,
check environmental variable LANG after LC_ALL and LC_CTYPE.
When determining the language, check environmental variable LC_ALL before
LC_MESSAGES and LANG (but after SURVEXLANG).
If we don't find the message file, only give an error if it was specified
with SURVEXLANG, since that is an explicit instruction to Survex, whereas
LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
There are a handful of hard-coded English message strings for reporting
errors trying loading message files, etc. These are all now ASCII, as if we
fail trying to open a message file, it's more likely the encoding isn't
Prune strings we are no longer using and are probably unlikely to use again
into a new file po_codes_dead, so that translators don't get presented with
them to translate.
Merge lots of translation updates. Most translations are now complete or
close to complete.
Add start of Indonesian translation from Arief Setiadi Wibowo.
Fix various compiler warnings when building from source.
Include scripts gdtconvert and gen_img2aven in the source distribution.
Changes in 1.2.6 (2012-02-23):
(Mac OS X version): Fix so that cavern finds its messages when run by aven.
(Microsoft Windows version): Include JPEG images for aven in the installer
cavern: If we have a reference to a station in a non-existent survey, give a
helpful error rather than saying the station hasn't been exported from the
survey. (Bug reported by Martin Green via email)
aven: Fix to build with a non-Unicode wxWidgets library. Patch from Olaf
findentrances: Add findentrances utility from Olaf Kahler which produces a
.gpx file with waypoints for entrances. This needs libproj so is disabled
by default for this release - to enable it install the development stuff for
libproj and build survex with:
make install FINDENTRANCES=findentrances
dump3d: Add support for showing img_ERROR_INFO items.
doc/3dformat.htm: Merge in some improvements from Mike McCombe.
Incorporate a French translation from launchpad I'd previously copied the
English version of by mistake. Attempt to correct mistranslation of "survey
Changes in 1.2.5 (2012-01-03):
The survey tree in the left panel is now in sorted order once more.
No longer fails with an assertion if used for a long time (we were leaking
an OpenGL list each time one had to be regenerated).
Now builds with newer FFmpeg library.
Draw measuring line in front of the indicators rather than behind them.
Loading a new file (or reloading the current one) no longer invalidates
the OpenGL lists for the compass and clino, so will be a fraction faster.
Improve handling of attempts to look up translated messages before the
message subsystem is fully initialised (which only happens if there's an
error early on).
Improve the survex(7) man page text, and fix it to be marked as section 7 in
the man page source as well as in the filename.
Changes in 1.2.4 (2012-01-01):
Changes in 1.2.3 (2011-12-31):
Fix to build with wxWidgets 2.9.2.
(Mac OS X version):
Processing .svx files from aven now works.
Remove spurious blank lines from the licence text in "Get Info".
Don't create the help menu at all, as it is empty (because the "About"
entry goes elsewhere) and sometimes seems to appear in the UI.
INSTALL.OSX: Update to reflect current status.
Fix Y coordinates of surface surveys on printouts. (Closes #32)
Improvements to text plotted on the survey pane:
- Support plotting Unicode character points > 256 by lazily loading the
data for them from the font file and plotting them with a direct call to
glBitmap(), which is slower but doesn't require a display list per
- Adjust the spacing from fixed width to putting a one pixel gap either
side of each one character (so two between adjacent glyphs). Mostly this
reduces the horizontal width, but it adds a pixel for characters like "m"
and two in a few cases.
- Fix .pixelfont file generation to correctly handle characters wider than
Fix expected cross shape so don't always reject using texture mapping to
As we read a survey file, eliminate tubes consisting of zero XSECTs as well
as those consisting of just one. Previously we would trip over the empty
tube later. Such tubes can for example be created by extend if a splay shot
is the start or end of a tube.
Make the green colour used for entrances in the survey tree the same
(slightly darker than before) green used for the entrance blobs.
Report the version of the library we're actually running with if built
against wx >= 2.9.2. Make it clear that the version reported is the
version *built* with for wx < 2.9.2.
img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
was no longer used - it certainly is!
Use curly double quotes instead of "`" and "'" to quote filenames, etc in
messages, and curly single right quote instead of straight ASCII apostrophe.
Fall back to using straight ASCII versions if we can't represent them in the
current character set.
Translation updates for Catalan, French, Slovak and Spanish.
Changes in 1.2.2 (2011-10-06):
Replace the textured-mapped font drawing with an approach based on
glBitmap. This doesn't suffer from the character alignment issues which
the textured-mapped fonts had, and is actually significantly faster on some
machines. The current font used is (mostly) fixed-width, but this isn't an
inherent limitation - it was just the easiest font data to convert to a
Fix assertion failure due to rounding differences on loading certain .3d
Fix assertion failure when turning on 3D passages if they stick out higher
or lower than any station. (ticket#29)
Fix grid not to disappear when blobs are turned on and blobs are drawn
If a degree sign isn't available in the character set in use, transliterate
it to 'dg' rather than skipping it.
Fix message which should have been a degree sign but got lost in the format
change for 1.2.0 and then got reassigned in 1.2.1. Externally, this means
that bearings in the status bar now have a degree sign after them if they
are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
Fix print dialog to calculate the scale required for "One page" right
before it calculates how many pages are required, so we don't end up
something other than 1x1 being shown when the user changes settings.
Update the calculations for picking a scale and for deciding how many
pages are needed to take into account the change in info box height made
Changes in 1.2.1 (2011-10-04):
Translation updates for US English.
Rename the "depth bar" to "colour key" in documentation, menus, etc since
it now shows colours for dates and errors as well as depths.
In the colour key for "colour by date", change "No info" to "Undated".
Remove the dark grey background from the colour key and just put a single
pixel black border around the colours. This is more in keeping with the
other controls, and means the colours are now on a black background so more
visually similar to the survey legs.
Move the colour key's "Undated"/"Not in loop" entry down a little to
improve the appearance. Make each section a pixel taller.
Allow "Colour by X" to be selected even if there's no data for X or only a
single value of X used (the colour key is much smaller in these cases, and
does still provide some useful information).
Fix incorrect calculation of depth colouring for survey legs which straddle
a depth band boundary.
The scale bar, compass, clino, and colour key now all have right click
menus which allow related actions to be performed (especially handy in
Improve the font used on the survey pane - it now contains the '-'
character (so the clino now shows negative angles as negative, and dates
in the colour key are now hyphenated). Also the spacing and alignment
are a little better, though still not perfect.
PLT file export now handles spaces and control characters in station names
by escaping them with '%' as in URLs.
Pressing "Enter" on a station in the tree control now centres the view on
The scale bar is now cached in an OpenGL display list since it often gets
redrawn exactly the same - for example, when rotating, panning, etc.
Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
then forces a refresh of the survey pane. This is intended as a debugging
aid - if pressing F5 changes the display at all then there's a missing case
where a list should have been invalidated (please report if you find such
a case as it is a bug).
We now automatically track which OpenGL display lists need to be
invalidated on window width or height changes.
Increase scale bar maximum width from 65% of the window width to 75% as it
was in 1.0.x (except that if that would overlap the clino we now reduce
that proportion down until it reaches 50%). Make the limit of zooming in
the same as in 1.0.x. (ticket#23)
(Linux version): Previously wxGTK didn't really handle showing a dialog if
the application was fullscreen (the dialog got opened under the main
window!) To work around this, aven would switch out of full screen mode
temporarily while showing a dialog. This case works properly with recent
wxGTK, so disable our workaround with versions we know work. Also, apply
the workaround only for wxGTK, not everywhere except on Microsoft Windows
as there's no reason to think we need it for other platforms.
Grey out the "View North" action when we're already viewing North, and
similarly for other compass points.
(Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
info in the "About" dialog.
Fix to set the correct filename on the root of the survey tree - previously
the filename of the previous file loaded was used!
The movie export code now works with newer versions of the FFmpeg libraries
as well as still working with older versions.
Fix mixed up messages - the print dialog now says "View" on the left
subgroup of controls rather than some unrelated message.
On printouts, combine the "Plan View"/"Elevation" info box field with the
field which gives the bearing and reduce the height on the info box by the
removed field, so it's now 3cm for plans and elevations, as for extended
elevations. Report the tilt angle for tilted elevations which it seems has
been missing for ages (it's not in recent 1.0.x either).
Tweak the exact positioning of informational text on printouts to look
nicer and make better use of the available space.
Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
Make the sign of the tilt angle for printouts consistent with the sign
shown by the "clino" in the survey pane.
In the "Print" dialog, when in plan view disable the "Plan view" button,
and similarly for the "Elevation" button.
(Microsoft Windows version): Sort out appearance of custom cursors.
If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
(Mac OS X version): F11 puts aven into full screen mode, but apparently
you can't get out again easily, so add code to explicitly check for F11
being pressed and toggle full screen.
(Linux version): Fix the RPM .spec file for where man pages now get installed
and package aven.svg and the vim support files. (Fixes from James Begley)
"make check" now performs several checks on the translation files.
More messages are now available to be translated.
cavern: Fix reporting of ranges of survey coordinates, which was broken by
the message handling changes in 1.2.0.
Fix warning when compiling with GCC.
INSTALL: Mention building wxWidgets with --enable-unicode. Mention using
sudo for installing on Unix.
In the manual, replace the instructions for building from source with a
pointer to the clearer instructions in INSTALL.
In the manual, make it clear that installing with administrator rights
also applies to newer platforms than XP.
Changes in 1.2.0 (2011-09-20):
Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
tests/smoke.tst: aven no longer requires an X display for --help or
--version, so replace skip of this check with a check that this remains the
We now use the standard .po and .pot file formats for storing translations
(rather than the Survex-specific messages.txt format), and then translate
these into Survex's .msg format.
(Unix version): Move survex man page to section 7 (since it isn't documenting
an actual command).
(Unix version): Write each generated man page to a temporary file, then
atomically rename, to avoid leaving an empty or partial man page behind if
docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
recurrence of that).
(Unix version): Default to installing docs into /usr/share/doc/survex rather
Fix handling of accented characters in the survey pane.
Aven icon redrawn in SVG format - it's now a vector image which looks
nicer at larger sizes.
Explicitly request double-buffering, which seems to be needed for systems
with GLX >= 1.3.
Fix crash while trying to load certain .3d files.
Movie export code updated to work with more recent versions of FFmpeg.
Currently this is disabled in Microsoft Windows builds, pending getting the
required libraries set up for building releases.
Reporting of errors during movie export improved.
Force playback speed to "x1" during movie export.
Use stock IDs for buttons where appropriate - such buttons may now be
rendered with icons on some platforms.
If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
(Unix version): Remove special handling for toggling "full screen" on wxGTK
as it's no longer required with modern versions.
Don't redraw the survey on every mouse movement in the survey pane unless
the measuring line is (or just was) active. (ticket #17)
Drop "non-fatal" from the report of how many errors there were at the end
of the run - it just confuses users - we won't even get here if there's a
Add --3d-version option to allow the user to specify the version of the 3d
format to output. (ticket#21)
(Mac OS X version): Fix buildmacosx.sh script to check where the temporary
volume actually gets mounted. Fix URL for downloading wxWidgets.
Changes in 1.1.16 (2011-05-16):
Translation updates for German, Spanish, Italian, Portuguese, Brazilian
Portuguese, and US English.
Use horizontal ellipses character rather than '...' and right arrow character
rather than '->' where these characters are available.
(Unix version): Link with -lGL, if it exists, to support linking with gold or
GNU ld --as-needed (Debian bug #615781).
doc/TODO.htm: Remove entries which have now been done.
(Microsoft Windows version): aven: We now include all the available
translations for messages from wxWidgets, which means that standard widgets
will appear translated where available even if Survex messages aren't
Changes in 1.1.15 (2010-10-15):
In the cavern log window, change the "Rerun" button to "Reprocess" to
follow terminology in manual and elsewhere. Fixes ticket#15.
When displaying output from cavern, don't update the window after every
line, but only when we don't have data from cavern pending. Hopefully
If we aren't using GL_POINTS for blobs, draw them using a series of
abutting lines rather than with gluDisk which is faster and gives a
Check whether blobs and crosses actually render correctly as points/point
sprites, and if they don't, fall back to drawing them with lines. The
best method is cached on disk, and rechecked automatically if the graphics
hardware is changed or the drivers upgraded.
Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
though, so we still enable USE_FNT by default).
Don't offer "All files" wildcard in presentation save dialog.
(Microsoft Windows): Handle filenames with non-Latin1 characters in in
(Microsoft Windows): Quote filenames with spaces and metacharacters in
when running cavern from aven. Fixes ticket#11.
editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
diffpos: Handle files with duplicate labels in better - extend generates
duplicate labels when it breaks a loop.
Enable eswap-break testcase now that diffpos handles duplicate station names.
New v7 of .3d format which stores survey dates as number of days since
January 1st 1900, so we now support dates from 1900-2078 (rather than
1970-2037) with a smaller file size. The img API is now versioned - you
can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
gives the survey dates in days in days1 and days2 instead of as time_t
values in date1 and date2. Fixes ticket#14.
Consistently use http://survex.com/ rather than http://www.survex.com/ - the
former has been the canonical name for some time, with www.survex.com just
redirecting to it.
(Unix version): Use unlocked file I/O if available, which can be much faster
in some cases (we don't need the locking as we don't do multithreaded file
(Mac version): Fix compilation failure due to clash with Point in Mac OS X
(Mac version): buildmacosx.sh now works again.
Most tests weren't actually running any testcases (looks like a sh
portability issue). This is now fixed, and fortunately all tests still pass.
Include the extra .isl translation files for Innosetup in the source archive.
Changes in 1.1.14 (2010-07-26):
Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
After processing survey data, if there were warnings or errors, add a
"Rerun" button to allow easy reprocessing after fixing problems. If there
were only warnings, also add an "OK" button to allow moving on to viewing
the processed survey data (fixes ticket#13).
Optimise updating of the cavern log window (hopefully fixes ticket#12).
Fix links in cavern log window to link from exactly '<file>:<line>' (and
not the ': ' after), and to make the title for the terminal the
warning/error message. Avoid false positives by checking that '<line>' is
Don't double escape the contents of href and target in links in the cavern
Improve handling of the splitter window, fixing behavioural glitches in
Highlight stations matching any current search when a file is loaded.
(Mac version): Fix build issue due to Mac OS X polluting the global
namespace with its own "Point" class.
(Unix version): The Gnome print dialog has its own preview window so
suppress ours if using the Gnome one.
(Unix version): Link aven with -lGLU which SuSE Linux needs.
(Microsoft Windows version): Fix handling of a double-click on the survey
tree when built with wxWidgets >= 2.8.11.
cavern: Report relevant file and line number for three warnings which didn't
give them before.
(Unix and Mac versions): configure: Update the wx-config probing code -
wxmac-config etc aren't present with newer wxWidgets versions so there's no
point looking for them now.
(Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
for easy installation. Update it to work with the latest Survex versions
(use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
private wxWidgets, use 2.8.11 not 2.7.0-1).
Fixed the cad3d man page, which was an empty file in 1.1.13.
Changes in 1.1.13 (2010-06-16):
Say "wxWidgets" instead of "wxWindows" consistently.
img.c: Fix small memory leak (filename_opened member).
cad3d, aven: Fix export to SVG when a label contains a '%' character.
wxWidgets 2.6.0 or newer is now required.
A "Unicode" build of wxWidgets is now supported. An "ANSI" build may still
work but hasn't been tested recently (all packaged versions of wxWidgets
seem to be Unicode now).
Fix potential uses of uninitialised variables which may have been causing
occasional glitches when loading a file on start-up.
Improvements to the handling of the font used for plotting labels and other
text on the survey pane:
- Loading the font file is more efficient.
- Character spacing is improved.
- Default font is now anti-aliased.
- Add "Copy" button to copy the system info to the clipboard for easier
- List OpenGL extensions last, since there are usually lots of them with a
modern gfx card.
- Fix 100% CPU usage while the "About" dialog is open.
Processing .svx files:
- Passing a .svx file on the command line now works better.
- Put the survey data log window in a splitter in the usual frame rather
than opening a separate frame for it.
- Auto-scroll the log window until we've reported a warning or error.
- Fix small memory leak.
The presentation filename now defaults to using the basename of the
currently loaded dataset, but we always prompt before we first save with
such a name.
Reduce memory usage when saving a screenshot.
Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
persist the window size (and maximised or fullscreen state) between
Fix reporting of OpenGL errors.
Fix glitches when tilting while looking East.
Added Portuguese and Slovak translations of wxWidgets messages.
Rationalise manual formats - replace PostScript with PDF and drop RTF.
Drop the "alternative manual formats" self-extracting zip file - people
will generally just want one of the formats, so downloading several
together isn't very useful.
3dformat.htm: Update for v6 format (thanks to Mike McCombe).
GPL.htm: Replace HTML version of licence with a link to the version on
the FSF website.
ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
low level to be of interest to non-developers, and developers can look at
the source code.
(Unix version): configure: New preferred name for specifying wx-config script
is WX_CONFIG. WXCONFIG still supported for compatibility.
(Linux version): Source RPM package dropped as you can just build an RPM
package from the source tarball.
(Microsoft Windows version): The installer is now created with a newer
version of InnoSetup, which gives a 10% smaller download.
Changes in 1.1.12 (2007-02-07):
Remember the window size or maximised/fullscreen state between invocations.
Add options dialog to "Export" similar to the one for "Print".
The "number of pages required" in the print dialog now updates when you
change what is to be shown (underground legs/surface legs/station
Changes in 1.1.11 (2006-11-25):
Updated Czech, Spanish, and Slovak translations.
(MacOS X version): Assorted OS X specific tweaks and fixes.
Pick a smaller and clearer font for labels.
Fix character spacing.
Tweak display of bearing and elevation angles to look nicer with
Use the title from the 3d (or plt, etc) file for the window title
rather than the filename.
Show distances to 2 decimal places rather than the nearest integer.
Only consider underground legs when calculating the depth bands and
Add "Colour by Error".
Add entry for "white" in date and error keys.
When setting the view to a single point, don't change the scale.
If reloading the same file, don't change the view
Fix filetypes selector in open dialog.
Fix the charset we use for aven in certain cases.
Call msg_init before using msg_lang or it won't ever be set!
Pass wx the full language code to initialise the C library locale.
Fix bug in generating prefix tree view which could lead to a bogus
leading dot on some survey names (bug probably introduced in 1.1.10).
"New Presentation" now ensures that the side panel is open
Fix updating of cached opengl lists when the view is reset to the
Ignore LANG if it starts with a digit to avoid problems with bogus value for
LANG which AutoCAD installation seems to set on MS Windows.
(Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
specified. Either/both can be set to ":".
dump3d: Report unknown (to dump3d) codes returned by img.
img library: Flag all stations as underground in the old "ASCII" .3d format.
Changes in 1.1.10 (2006-07-14):
aven: Clicking on a survey name in the survey tree now highlights it in
the map view. Double-clicking zooms the view to show the clicked survey
highlighted. Clicking the root clears the highlighting and double-clicking
the root restores the default view. To expand/collapse a branch, click
on the "[+]" or "[-]" icon to the left of the survey name.
aven: The measuring line can now measure to anywhere in plan or elevation
view (not just to a station!) In plan view the horizontal distance and
bearing are shown, while in elevation view the vertical distance is shown.
aven: Moving the mouse over a station in the survey view now highlights
that station in the survey tree (though it may not be visible if the
survey(s) it is in aren't expanded).
aven: Clicking on a station to centre the view now moves the mouse pointer
to the new location of the station (except on Mac OS X where this isn't
aven: Fix which presentation toolbar buttons are shown as depressed.
Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
vim files are now installed with the correct paths (bug introduced in 1.1.9).
Changes in 1.1.9 (2006-07-04):
(Unix version): Install desktop files for aven and svxedit contributed to the
Ubuntu package by Phil Bull, and corresponding pixmaps.
Fix img to filter out cross-sections which don't match the subsurvey (if
specified). The API now returns img_XSECT_END to mark the end of a
passage rather than setting a flag on the last img_XSECT of the passage.
Enhance integration with the vim editor - this can now colour .err files, run
cavern from vim and parse error output, and run aven from vim. Tweak the
existing vim mode for .svx files to fix a few minor bugs and add support for
the new "*data passage" style.
aven: fix drawing of the "blob" end of the measuring line on graphics cards
which can't draw large enough blobs for us.
aven: sort out confusion about what encoding everything is in which means
that the distance measured by the measuring line actually gets displayed
and also fixes problems with empty menu items in non-English locales in
aven: redraw grey background after a menu is closed over the aven window
with no survey loaded.
aven: fix bug which caused printing to crash (introduced in 1.1.8).
aven: avoid crash on some machines when opening "About" dialog before having
loaded a survey.
aven: Translate "Plan" and "Elevation" buttons in print view dialog.
(Unix version): aven: Fix character set handling of cavern output.
cavern: Report an error if a cross-section is specified for a station which
Updated French and Italian translations.
(Unix version): aven: Fix "Can't open message file `en_US' using path
Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
(doesn't affect Survex itself, but other applications which use img.c should
update their copy).
(Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
and later are caught by configure, whereas older wx versions are caught when
trying to compile).
Changes in 1.1.8 (2006.06.30):
Drop support for building with wxWidgets versions prior to 2.4.0
(which was released on 2003-01-07).
aven: Printing through aven now uses settings from the "[aven]" section
of print.ini, and support for hierarchical sections (using "like=")
has been disabled.
aven: Change mouse actions to be compatible with those in Survex 1.0.
The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
left drag is now smart about not rotating and zooming at the same
aven: Highlighting stations now happens as you type, and pressing
"Enter" or clicking the "Find" button now pans and zooms to show the
aven: Left-clicking away from a station now cancels measuring line.
aven: Setting view to North, South, East, or West is now animated like
the tilt from plan to elevation.
aven: Fix presentation saving to also write "." for decimal points and
presentation loading to accept either "." or ",".
(Unix version): aven: Add text for all toolbar items so that aven
will work with the Gnome desktop preference for displaying toolbars as
icons with text or just text (wxWidgets needs fixing first though).
(Unix version): aven: Remove the ability to detach the menu bar (yell
if you actually used it and I'll restore it!)
aven: Add "all survey files" option to the "open file" dialog.
(MS Windows version): aven: Fix cursor keys to pan survey.
(MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
(MS Windows version): Fix installer to work on Windows 2000 or XP if
run by an unprivileged user.
(MS Windows version): Upgrade to the latest version of InnoSetup (the
installer builder we use) and include new installer translations for
UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
(MS Windows version): aven: Include Catalan and Brazilian Portuguese
translations of messages for wxWidgets (the GUI library we use).
aven: Disable "Highlight exported points" if there aren't any.
Updates to French translation from Michel Bovey. Also updates to German,
Italian, Catalan, Spanish, and Romanian translations.
(Unix version): test suite: fix smoke test to pass even without X running
(it was meant to but the code had a bug).
aven: Check if OpenGL is available and exit cleanly with a helpful error
if it isn't.
(Unix version): aven: Fix --help and --version to work without a working
X display (provided it's built with wxWidgets 2.5.1 or newer).
aven: Automatically select the presentation tab of the notebook when the user
selects "New Presentation" or "Open Presentation".
aven: Fix "Delete" in the presentation list to not get passed on (and so not
reset to default view as well).
aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
aven: Fix Cursor Up and Down in the presentation list to move the highlight
up and down instead of being passed on and moving the survey.
aven: Improve SVG output compatibility. Tested with Mozilla Firefox 1.5,
Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
Safari 2.0.3, and InkScape 0.42.
aven: Put a 5mm border around exported SVG files to allow for station markers
and non-zero width lines.
aven: Fix crash when exporting as SVG or Sketch if labels or surface data
was turned on.
aven: Actually close the file we're exporting which fixes problems with it
not always being fully written.
Changes in 1.1.7 (2005.10.18):
cavern: Add validity checking for dates in *date commands (with feature
test in testsuite). A date entered as just "year" or "year.month" now
becomes a date range for the relevant period (previously it became a single
date near the middle of that period).
extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
with MS Windows).
extend: Default output name for a file called input.3d is now input_extend.3d
rather than just extend.3d (which was annoying if you wanted to extend
several surveys in the same directory).
aven: OpenGL 2.0 always includes support for point sprites so rework
our check for them to include that knowledge.
aven: Regenerate depth bar if user switches to/from metric units.
aven: Don't clear the "there" mark just because the mouse pointer has
moved off a station.
aven: When processing a .svx file, put the resultant .3d file in the
same directory (since that's where we then try to load it from).
aven: Fix labelling of date colouring on 32 bit platforms.
aven: If "colour by date" is on and we load a survey with no date info
(or all surveyed on the same date) then set "colour by none".
aven: Make the error dialog modal and remove a signal handler once it
has fired to prevent endless (or seemingly endless) cascades of error
aven: Enforce a minimum object volume diameter of 1m to avoid problems
if a survey file with only one station in is loaded.
aven: Fix problems with indicators disappearing when we're drawing
blobs and/or crosses the slow (but always supported) way. (Problem
introduced in 1.1.6).
(Unix version): aven: Really stop setting extra toolbar margin when using
GTK2.0. The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
(Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
we've been compiled with, and which GTK+/Motif version where appropriate.
(Unix version): Fixed build on Fedora Core 3.
documentation: Updates to 3d file format specification from Mike McCombe.
Changes in 1.1.6 (2005.10.10):
(MS Windows version): Distribution is about a third smaller than 1.1.5
(mostly because mingwm10.dll is no longer required).
aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
it, showing cavern's output in a window (with errors and warnings clickable
to load the offending file into an editor), and then loading the resulting
aven: Added "Colour by Date" option.
aven: Disable "Colour by Depth" option if there's no elevation variation.
aven: Don't crash if trying to load a survey with no elevation variation.
Instead turn off depth colouring.
aven: Export as HPGL added.
aven: Improved update of mouse coordinates and measuring line (thanks to
aven: Show the coordinates of either the mouse pointer or the nearest
survey station to it (if there is one near enough). Showing both was
confusing and meant the status bar overflowed on smaller displays.
aven: When printing an extended elevation, don't show bearing and elevation.
aven: Don't lock "flat" surveys which aren't extended elevations - a
flat survey with LRUD data isn't flat any more!
aven: When we have to draw blobs and crosses the slow way (because the
graphics hardware doesn't support the fast way), draw them so that they
should appear at the correct depth into the 3D scene instead of on top
of everything else.
aven: Make "play presentation backwards" icon green to match the other
(MS Windows version): aven: Mouse clicks on the survey view now set the
keyboard focus there.
(MS Windows version): aven: Fix first redraw of a newly loaded survey.
(MS Windows version): aven: Fix redrawing of measuring line.
cavern: Store dates for img_XSECT.
cavern: Fixed small one-off memory leak if you specify -o more than once.
(Unix version): Check environmental variable LC_MESSAGES when deciding what
language to use for messages.
(MS Windows version): "Print" on a 3d file now prints through aven rather
than the separate printer driver (Unix has done this for some time).
Removed old printer drivers.
img library: When creating a 3d file, ignore img_XSECT if we've been asked
to write a file format version which doesn't support it.
Changes in 1.1.5 (2005.09.20):
(MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
aven: Make blobs round like they are in Survex 1.0.
aven: If the graphics drivers don't support drawing blobs using OpenGL
point markers, fall back to drawing filled circles.
aven: If the graphics drivers support it, draw crosses as texture mapped
OpenGL point markers which is much faster.
aven: Cross size increased to match Survex 1.0.
aven: We must update which blobs are displayed if display of surface or
underground legs is toggled.
cavern: Fix handling of a *solve followed by survey data, none of which is
attached to the previous data.
cavern: Fixed "No survey data" error when a *solve is followed by another
*solve (or the implicit solve at the end of processing) with no data between
Changes in 1.1.4 (2005.09.19):
aven: Added Aven's icon to the "About" dialog.
aven: Use localised character for the decimal point (e.g. "," in most
continental European countries).
aven: Previously the survey tree would get focus and then take keypresses
(e.g. "P", "L", "Delete"). Now we pass most keypresses across so they
operate on the cave, and transfer the input focus across when we do.
aven: Make pressing "Return" in the tree control expand/collapse a subtree.
aven: Speed up intialisation by delaying creation of OpenGL lists until
aven: Added Mark Shinwell's bounding box with shadow of the survey.
aven: Disable the "Tubes" button/menu item when there's no LRUD data.
aven: Reworded "Restore Default Settings" as "Restore Default View".
(Unix version): aven: Set sensible default margins for printing and preserve
any margin values the user specifies between runs (previously margins
defaulted to 0 each time aven was run).
Documentation: Document *DATA PASSAGE in the manual.
Changes in 1.1.3 (2005.09.07):
(Microsoft Windows version): Fixed build problems.
cavern: Allow OMIT character (-) for left/right/up/down.
aven: Remove an unnecessary menu separator.
aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
aven: Make the tooltip for "Hide" show the number of found stations.
aven: If * or ? is used in a glob-style pattern, force a non-substring match.
aven: Enable "New Presentation" when there's a 3d file loaded, rather than
when there's a presentation loaded.
aven: Make entrances green in side panel tree list to match green blobs used
in cave view.
aven: Don't show surface labels if we're not showing surface data, etc.
aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
make "Space" the key for this. Keep Return working "Stop Rotation" so
existing users are happy, but don't advertise it.
aven: Normalise filename by adding any extension used, and use the normalised
filename for file history and window title.
(Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
as the toolbar buttons already have a sensible margin - the extra margin is
only needed with GTK1.2.
aven: Fix handling of plumb legs in tube model.
aven: Fixed swapped L and R in tube model.
extend: Preserve UD cross-section information in extended elevation.
extend: Add new messages for John Pybus' enhancements.
Changes in 1.1.2 (never formally released):
Added support for LRUD data in .svx files, in .3d files, and aven can
now load and display it on screen and on printouts. The ability to "fake"
LRUD data in aven is gone for now but will reappear in some form later.
cavern: Removed support for writing Chasm's 3dx format. We're going to
fold any desirable missing chasm functionality into aven.
aven: Rearranged mouse actions as discussed on the mailing list. Added
cursors for each different mouse action to help the user learn what each
does. Also added cursors for the "compass" and "clino" as well as the
scalebar to suggest to the user that they can be dragged to change the view.
(Unix version): aven: Don't segfault if LANG isn't a known language.
tests/smoketest.tst: If X windows is running, check that we can run aven
with --help and --version.
tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
no results are listed for it. This revealed that there was a "newline" test
which should have been called "badnewline", and was a broken testcase too!
Fixed all these problems.
cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
and omitted forward compass/clino readings in Compass DAT files. Added
a feature test for this to the testsuite.
It no longer makes sense to have an option not to build aven or to build aven
without OpenGL so remove old machinery for this from configure and the
(Unix version): configure: Check if "-lXxf86vm" is needed.
configure: Better output for strcasecmp test.
aven: Fix crosses to work much better. Not a total fix - their position
in the Z buffer isn't correct and they're rather slow to plot.
aven: Don't regenerate the hittest grid every time the mouse moves while
animating, which solves the mysterious pausing effect (thanks go to Martin
Green for spotting this!) Also clear all the status bar coordinates when
aven: Sort out clashing menu shortcuts in some languages.
aven: Fixed compilation problem on x86_64
SPUD: Pruned out stuff which has been done or which is not actually relevant
to this branch.
Merge various changes from 1.0 branch:
aven: Port over "printing from aven" functionality.
aven: Port over "export as" functionality,
Add David Loeffler's vim mode for .svx files.
aven: Fix check for whether a label is behind us in perspective view.
aven: Don't use an opengl list for drawing the indicators - we typically make
a new list each time we plot them anyway.
Remove lingering traces of support for RISC OS and pre-386 MSDOS
aven: Set icon on non-Windows platforms too. This means that with
WindowMaker on Unix you get an icon on the AppIcon by default.
configure: Update wxWindows checks to handle newer wx versions.
Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
problems. They also all require Perl 5.8 now (hopefully this isn't an issue
for anyone building from CVS).
acinclude.m4: Quote macro name for fix autotools warning.
Documentation: "tilt up" is "'" not ",".
aven: Add support for mousewheels (to tilt the cave).
aven: Fixed twisted transitions to and from pitches in certain cases.
aven: Pick a sensible initial window size when the user's desktop is spread
over more than one monitor (works best with wx2.5 or newer, but try to do
better with wx2.4 or earlier as well).
aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
contents being visible before any survey is loaded.
aven: Allow a coloured texture to be used
aven: Don't initialise until we have data (to the user, this means the window
is default colour (grey for most systems) not black until a survey is
aven: Fixed weird "shadowed" icons.
Changes in 1.1.1 (2004-10-06):
(Microsoft Windows version): aven: Hopefully fix loading a survey file at
aven: Delay loading the bitmap for the "About" dialog until it is first
needed. We want start up to be as quick as possible.
Changes between 1.0.32 and 1.1.0 (never formally released):
NOTE: Survex 1.1.X releases are development snapshots made available for
the purposes of allowing wider testing and getting more user feedback. Once
the code has stabilised the version number will be raised to 1.2.0.
aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
you're using Windows 95 - these can be obtained from:
aven: Solid passages - passage dimensions are currently inferred from
the leg length (pretty effective as you can measure longer legs in
larger passages). Use of real LRUD data coming soon...
aven: Depth colouring is now continuously varying.
aven: Colour by depth can now be turned off (and there's the start of a
framework for properly implementing colour by date, error, etc).
aven: Find stations moved onto the toolbar and now uses a simple wildcarded
match (? matches any character, * matches any number of characters).
aven: We now use the status bar for coordinates, distances, etc to make
better use of screen space.
aven: Full screen mode (F11).
aven: Perspective view.
aven: Context sensitive cursor shape - needs more work.
aven: Mouse actions changed (hopefully they're now more natural, but
you may find the change disorientating - feedback wanted on this).
aven: Added "presentations" which allow you to set up fly-through paths
and load/save/run them.
aven: A presentation can be exported as a movie file.
aven: Added Save screenshot facility.
aven: Depth fogging option.
aven: Added Smooth Lines option.
aven: Added Textured Walls option.
aven: If a survey has surface legs but no underground legs, default to
showing the surface legs.
cavern: Dates given to *date are now stored in the 3d file.
