I have several 2d-textures that I want to map to different sections of a gluSphere. Anyone have any thoughts on how I can get the correct texture coordinates for the task?
With gluSphere you can only generate one set of texture coords. You can use multiple calls to gluSphere with blending, to get a sphere with a lot of textures one over the other in arbitrary ways. You can play with teh texture mapping using the texture matrix for each pass.
Or, you can do your own sphere.
