Hi,

If your geometry and volume data is decoupled, this is quite easy. Otherwise you could "carve" out the structure by altering the volume data directly.

Have you tried letting OpenGL generate the texture co-ordinates (OBJECT_LINEAR) when you draw the shape?

(using glTexGenf( GL_S, GL_TEXTURE_GEN_MODE, GL_OBJECT_LINEAR) etc.)

That should work if you have a true 3D texure setup.
