Hi, Thomas and all.

I too used inverse kinematics to make it easy to pose the mannequin. The
method I use in POVRAY involves simple rotation about the joints. For
example, if you wanted to move the arm you would rotate the upperarm about
the shoulder and the forearm and hand would move accordingly, of which also
have their own rotation (i.e. about the elbow and wrist).

If it helps, I could post the coding for POVRAY for just the arm, for
example, and I'd be interested in your comments, suggestions, etc. It's
just the matter of treating the limbs as vectors and the joints as the
endpoints of the vectors.
