Halo,
Is it posible to update the constraints of rotation after they have been specified? also, have you thought of implementing a feature like 'Grab' where an end node will move towards an object by rotating the appropriate joints?
Ie. Avatar turns body to face the apple, and lifts upper arm and lowers lower arm, adjusting each until the collision is made between the apple and the hand node.
I was trying to work out the best way to do this, and i wouldnt mind getting a hold of some code for the physics engine you wrote so i can see if it can have the feature added. If u pass a copy my way i could have a crack at adding it. I would release me code as well.
