Anatomy-based Kinematical Joint Model with Soft Connective Tissues

However, in human body animation, joint models are often poor simplifications of real joints. They are usually based on classical works in Robotics, where joints are rather idealized and not conceived to deal with many important biological issues. It is not crucial for Animation because the details of joint motion have little influence on global motion, and other animation techniques are able to mask imperfections. Other science domains, like Biomechanics, addressed the problem differently. Because of their specific interests, they have created models that describe better the lower level details of joint motion. But, in turn, they usually neglect visual and interactive aspects.
