In the java docs:
There is a two step action:
1. set the texture coordinates in your geometry, where you specify to which
texCoordSet you set the coordinates:
"http://java.sun.com/products/java-media/3D/forDevelopers/J3D_1_3_API/j3dapi
/javax/media/j3d/GeometryArray.html#setTextureCoordinates(int, int,
float[])"
2. set the TextureUnitState in the Appearance object, where the index
specifies to which textCoordSet will be applied the texture:
"http://java.sun.com/products/java-media/3D/forDevelopers/J3D_1_3_API/j3dapi
/javax/media/j3d/Appearance.html#setTextureUnitState(int,
javax.media.j3d.TextureUnitState)"
You may omit step 1 if you specify in the TextureUnitState a
TexCoordGeneration object, i.e. if one of the texture should represent
reflexions, refractions, spheric coordinates, etc.
Regarding your guess, that's the most complicated approach ! You should use
2 shape3d's. Multitexturing was specificaly designed for combining textures
at runtime, i.e. a basic texture with a reflected one or more elaborated
efects. I just don't understand why you don't want to use different shapes.
Can you explain the reason ?
Cheers,
Florin

yeah, I Guess I could use sets. That seems like the most simple way to
solve
this problem. Is there a place somewhere where I can read about this? How
do
texture sets work??
thanx
