>I finally isolated the textures problem that we were having in our applet.
>Basically the problem was that textured geometries (with texture coordinates
>as a part of vertex data) would not display textures in immediate mode on
>NVIDIA card (RIVA TNT2, GeForce2 MX, and possibly others). I was able to
>work around this problem by using automatic texture generation object in
>appearance. However this feature does not work on ATI Rage Mobility card,
>neither in immediate mode, nor in retained. I've also found out that if
>immediate mode is used from the very beginning (not a single retained mode
>render), then these bugs can't be reproduced. See the example that I've
>attached for the details. Since both NVIDIA and ATI cards are rather
>popular, we can't use one of the methods above and have to ask Java3D team
>to fix this problem or suggest some work-around.
