Hi torolf

Soooo, what formula parts are used...

1. one part defines an endless structure (e.g. your cube_knochen)
2. one part defines the limitation figure (e.g. sphere or cylinder).
(have you tried it with a torus too?)
3. If there are too colors two structures are used, where the second is shifted a little bit

Laughing Gerd

ps. an example code would be welcome...
