This video demonstrates a finger inverse kinematics solver I wrote.
The original purpose was to use this solver to reconstruct hands as detected by Leap Motion device (leapmotion.com). The red spheres represent the data returned by the Leap SDK, i.e. the finger tips position and orientation as well as the palm position and orientation.
However, because the palm position computed by the detection algorithm seems to be influenced by the finger tips position, it can't be used reliably as a fixed point on the hand. Therefore the approach of using this data as input for this IK solver can't be applied.
