Notes about computation of inverse kinematics[1]
At this moment, the research is focusing on solving a 2 bones system, the leg in this case, but it would be applicable on the arms or any other part of a skeleton having at least 2 parents.
The main issue seems to be the computation of the knee position. All distances are easily computed:
- upper leg (red) keeps its length
- leg (yellow) keeps its length also
- distance between the target and the origin of the upper leg can be easily computed in world space.
