Anatomically Correct Animation of a Humanoid

The human body is one of the most mysterious and fascinating works that nature has ever created. One of the most important requirements for its correct simulation is the animation of its virtual skeleton. It thus becomes useful to be able to ensure that the animations meet the biomechanical constraints of the human body, with minimal recourse to human assistance. We studied several existing techniques of adaptation of animations to skeletons, limitation of rotations in joints with various degrees of freedom, and coupling of motion of joints that in the human skeleton also move together. We developed a model for a skeleton with integrated biomechanical constraints, and indirect driving of some joints. We examined the adequacy of the chosen techniques, pointing out some aws that currently prevent the proper use of the skeleton and also proposing solutions for them.
