    Simulating coordinated movement with tendons



    Despite significant advances in the research of human movement [Kry and Pai 2006], simulating the dynamics of the human body, such as compliance coupling between joints, remains challenging. Simulating biomechanics is difficult, in part, due to the complex inter-dependence between tendons and bones. Modeling this interdependence is necessary, however, since much of the coordinated motion in human biomechanics is due to the specific ways in which tendons are arranged with respect to bones. Accurate tendon modeling is also important for visual effects, since tendon motion has a noticeable effect on skin deformation. We address these issues with a novel simulation framework that efficiently and accurately models the coupled dynamics of tendons and bones.
