A finite element method is used to simulate the deformation of soft body. The crucial procedure of cutting simulation is the geometry remeshing. During remeshing, the inner topologie consistence need be considered. Previously, a large number sub-tetrahedral is used to avoid the consistence problem or an additional algorithm is used to check and adjust the geometry to keep its consistence. In this...
Haptic enabled virtual reality surgical simulators are increasingly replacing more traditional training tools in teaching hospitals. Development of these simulators may be greatly facilitated using physics libraries such as NVIDIA's PhysX. While volumetric models of soft bodies may be easily generated and simulated using such engines, it is not straightforward to develop complex surgical tasks such...
