As a warning, these tools should not be considered stable. They're not even "beta". They're in development and not thoroughly tested. You shouldn't be able to experience anything worse than a program crash, but for legal reasons I can't be 110% sure about that. You can help by reporting bugs or by providing testing: see the contact page.
Win32 builds of the most recent version of Qwalk model converter and model viewer:
Alpha 0.1.2 (October 23, 2010): Download (265 kb).
The program has, at some point in the recent-ish past, been compiled and run on 32-bit Windows (XP) and Linux. Beyond those platforms it may have some trivial compile errors. If you would like to help with porting or testing, let me know. It won't work on big-endian machines at all: I still have to work on that.
The Subversion repository is located at svn://svn.icculus.org/qshed/trunk/qwalk/. To check out the latest version of Qwalk, type the following command (assuming you have a Subversion client).
svn co svn://svn.icculus.org/qshed/trunk/qwalk qwalkand then build it by changing to the "qwalk" directory and typing:
make all(Or type make on its own to see a list of options.)
The SDL library is required to compile and run the viewer (but not the converter). LibJPEG is dynamically loaded on demand, so you only need it if you are going to load JPEG textures.
CAUTION: I suck at makefiles. Dependencies don't work. You should make clean before every compile. If you would like to contribute a better makefile, I would be grateful!
