#58 | wontfix | About box photo missing on OS X | ||
Description |
Phil Maynard reports that on 10.6.8 the about dialog throws up an assertion failure when opened: ../src/osx/core/bitmap.cpp(1501): assert "IsOK()" failed in GetHeight(): invalid bitmap If you answer "No" to "Do you want to stop the program?" you get the about dialog, but the cave image is missing (only image is the aven icon).
This sounds like it is failing to load That leaves the question of why the image is failing to load. I tested the about dialog worked on OS X at some point between 1.2.18 and 1.2.19, and didn't get this assertion, so it may be related to the OS X version, or to changes after that. |

#56 | fixed | Sort out handling of geoid | ||
Description |
Currently the altitude of GPS fixes and hence of cave entrances attached to them doesn't match the altitude of terrain from DEM files very well - the difference seems to be a few 10s of metres. Newer versions of proj have support for geoids, which should solve this: https://trac.osgeo.org/proj/wiki/VerticalDatums I think proj >= 4.8.0 is needed - the release announcement for it includes "Added preliminary vertical datum support". That was released 2012-03-14, so shouldn't be an unreasonable requirement. It would be good to coordinate how vertical datums are handled with therion, but they didn't respond to my email to their list about doing so. |

#55 | fixed | Fix terrain rendering to not show terrain through itself | ||
Description |
The terrain is rendered with a Z-prepass, which is supposed to achieve the desired effect. This actually worked on my netbook running a rather ancient Ubuntu version and with a hand-built wxWidgets 2.9.5 (though the wx version seems less likely to matter), but not since upgrading it, and not on two other Debian machines I have tried. I modified the glxgears program to use a Z-prepass, and that seems to work, so I just need to determine what's different in aven. |
