Thank you Jaime for the explanation. I assumed that "rigid body" is a fixed term
within a certain branch of computer sciences. But since we have so many branches
nowadays I simply could not put it. Now I think Gfans tries something similar to
your Bullet Physics and so you may be his best advisor. I do not like bullets,
since they are designed to kill people, but I really like your animations and I
really wonder how your animaton would look like using this cat from John (and
the boulders Christoph has proposed).But this is another story.
I could not do this job. My interest in CG is more the work of Przemyslaw
Prusinkiewicz, which I observe closely and hope to have an implemntation to
(Uber-)POV someday.


Best regards,
Michael
