Here is the code TextureTest from the java3D demo.
I've modified it so that the texture and lighting are enabled together (by
adding a GENERATE_NORMALS to the Box and adding a default Material
to the appearance to enable lighting).
Now this code is working fine with Java3D1.1.1 on SGI 320 and STB Velocity 4400
but doesnt work (texture but no lighting) with Java3D1.1.2 ...
Thanks for the help and suggestions.
