Most deformable object simulators suffer from stability problems caused by material slivers in the cut vicinity. The extended finite element method (XFEM) is a novel approach that uses element enrichment to effectively model discontinuities. In combination with an appropriate mass-lumping technique, XFEM provides a stable simulation regardless of cut(More)
In this paper we introduce a new approach for the embedding of linear elastic deformable models. Our technique results in significant improvements in the efficient physically based simulation of highly detailed objects. First, our embedding takes into account topological details, that is, disconnected parts that fall into the same coarse element are(More)
Real time tissue deformation is an important aspect of interactive virtual reality (VR) environments such as medical trainers. Most approaches in deformable modelling use a fixed space discretization. A surgical trainer requires high plausibility of the deformations especially in the area close to the instrument. As the area of intervention is not known a(More)
Diese Dissertation ist auf den Internetseiten der Hochschulbibliothek online verfügbar. ABSTRACT There is a wide range of virtual reality (VR) applications that benefit from physically based modeling, such as assembly simulation, robotics, training and teaching (e.g., medical, military, sports) and entertainment. The dynamics of rigid bodies is well(More)
