Hi Angus,
thank you very much for your help! I really appreciate it.
We have a GeForce4 Ti.
I tried a smaller volume and a single component texture but this
didn't help. I don't think that texture size is a problem, because
a volume rendering programme of a collegue which uses only OpenGL works
well
with GeForce4 Ti. My own programme doesn't use glClipPlanes, so I
guess this is also not the problem.
Do you have any other idea why 3d textures don't work with Performer on
GeForce4? Is there a possibility to check if a texture is loaded?
Has anybody tried 3D textures with Performer on linux systems?
Thanks and Best Regards
Daniela
