Within POV-Ray, Inverse Kinematics would be the way to go. I have used 
that technique, not for animations, but to make wind-bend plants for 
instance. Moray was great for Inverse Kinematics use.

You are referring to the discussion in the TinaCheP forum between DrNo 
and me. I don't know what technique DrNo is using for his film as he is 
his own developer. The discussion was mainly about the storyboard and 
some visual glitches so I am afraid not many technical details were 
revealed.

I was interested in possibility of a render to keep geometry between frames. It
was my delusion. Only UberPov has some abilities.
The idea was: to create one file for a scene and, thus to kill parsing time.

I met this problem also. Could you please give some more details? It will be
very nice if you can give an example. Thanks a lot in advance.
