I do (still) see problems with VPython on Leopard. Here's the gory detail:
My MacBook Pro (Intel core duo, 2.4 GHz, 2 GB of RAM, GeForce 8600M GT
(256 MB VRAM)) came with Tiger (10.4). I installed and ran VPython 24
without problems (at least I think there were no problems; I didn't try
every example program).
I just did a clean install of Leopard (10.5). I installed the version
of X11 that came on the DVD; also XCode tools from the DVD. I installed
the newest Fink. Using that, I installed VPython2.5, from source.
After a struggle to reset X11 key/mouse preferences, and another
struggle to reconfigure IDLE, mouse input *mostly* works okay. But:
On a number of the sample programs the rendering is wrong. It looks as
if the z clipping plane is much too close. These include bounce.py,
bounce2.py, gyro.py, gyro2.py, and toroid.py. Parts of the scene are
cut off, but become visible as one rotates the camera.
In tictac.py, I can't get mouse input to work. If I zoom out, I see an
artifact at the bottom of the display.
glxgears runs okay (very fast). glxinfo gives a long list of stuff that
looks reasonable. (Are there other OpenGL test programs I should try?)
In principle this could be a graphics card driver problem; if so I
should have seen the same problems on Tiger. I didn't test every sample
program, but I think I would have noticed...
