Original Abstract

Simulation of dynamic motion of soft tissues is one of the most important topic in nowadays computer animation of human body. So far various elastically deformable models were used for this purpose. We present the extension of model proposed in [Terzopoulos et al 1988] with volume preserving constraint. We provide also evaluation of the constraint accuracy on two simulation experiments. Furthermore we add model of active and passive force generated by musculo-tendon unit using Zajac's bio-mechanical model. We use Finite Difference Method for resolution of continuous partial differential equations of internal elastic forces of the model in space. We integrate resulting ordinary differential equations of motion using various explicit and implicit methods.
