I'm completely new to graphics programming and openGL but this site has been very helpful, especially the demos. I have a question though, how do you add texture to a sphere or a cylinder? I see from the demos that for 2D objects, you should specify the corners of the object to the corners of the texture, but how do you do that for spheres? Thanks

I can't remember the functions name or params, but OpenGL can automaticaly set up texture coords for quadrics. In the same tutorial you learn quadrics in should be that function.
