In case I want the Texture to be different in dependency of Depth.
Especially useful for textures created through algorithms.

Maybe use a second texture of different size, they'll overlap different
everywhere...

what do you mean exactly? the Texture is just like Paint on the surface; it
doesn't change geometry... If you'd like to do something like cutting
something out of the outer skin and having a different texture for seeing
the inner stuff I suppose you'll need
a 3D-Texture with some spherical mapping. Too bad, I don't know if it is
supported by Java3D.
Another way is modeling your geometry and using a program to paint the texture
directly on it (or through unwrapping). Then you use the resulting texture
in Java3D for your object.
