I have some motion capture data (kinect) that records all body joints (32fps) and I want to take particular positions (for example when a person moves both of his hands up in the sky in celebration form) and find the forces that are being performed on each joint (or each bone). But what I really want is only the inside forces, the forces that the muscles perform, not gravity or wind or any other force. Can that be done using Open Dynamics Engine or Bullet. And if so, how? Is there a tutorial of some kind (I haven't found any yet)
EDIT-- The data that I currently have is xyz coordinates for each joint in each frame (as I said before 32 fps). It's easy to calculate the relative distance each joint made but what I need is the force applied to that joint and bone and maybe joint orientation if the force applied made the joint change orientation. I know that ODE and Bullet can take the dynamics of a 3D world (given by the programmer) and attach them to objects creating real world physics. What I need is to invert this process
