I've made a complete POV robot system it's at
http://leroywhetstone.s5.com/
You could use it to make mannequins.
I tried to clean up and document the code.
If you check it out I'd appreciate hearing any comments.

Hi Leroy.
I'm sorry but your version is too complex for my needs, my mannequin uses
simple rotation to achieve the correct poses. But could you please tell me
if your system uses IK of FK, and which you think is best.

You may be right about it being complicated. It started is out as a
stick figure
using rotation to position body parts. I still use rotation to position
the parts, but I've put the angles in a file. I did that so I reuse and
keep track of poses.(very helpful for animation)
So I guess my system uses FK. I don't know which IK or FK is 'Best'. I
know
it is relatively easy to create a KeyFrame animation that's FK. The code
I used to calculate inner frames is base on a simple function a+(b-a)*P.
Where 'a'is an angle of the first frame 'b'is the angle of the last
frame 'P'is the current inner frame divid by the total number of inner
frames.
