Abstract
This paper describes a hybrid modelinghybrid-modeling scheme of soft tissue deformation for a virtual reality based medical simulator. By using two different physically based models, it satisfies petitive requirements of real time performance and accuracy. A local point collocation-based method of finite spheres is coupled with a global boundary element technique to capture local features of the interaction (., non
