to add spheres in the next weeks, maybe some more shapes.
But you are right, we have to think about how to define a surface of a
sphere. Hehe... projecting onto the sphere would be cool, but I'm
afraid that wouldn't be too easy. There is another tutorial oin how to
create a textured sphere w/o GLU:

I'm going to investigate in that direction a little bit further.
Actually, the biggest problem would probably be legal issues. We had
already spheres and other shapes in GEF3D, but I had to delete them for
legal reasons for getting GEF3D IP approved.
