Hi Sadi,
a good thing to get you started probably could be to have a close look
at the H-Anim (Humanoid Animation) specification:
http://www.h-anim.org/Specifications/H-Anim200x/ISO_IEC_FCD_19774 . I
think looking at that documentation will point you to the right
direction if you want to interactively change the posture of a human model.
I'll watch this topic, I'm curious abut it. If you need any input, let
me know!
Kind regards and good luck,
Chris
