Title

Interactive Soft Tissue Deformation Simulation Using Physically Based Modeling

Abstract

This paper presents a study on physically based modeling and simulation of soft tissue deformation, with the goal of producing realistic, real-time effects during the simulation. We consider soft tissue deformation as a solid mechanics problem with a linear elastic constitutive law. A point collocation based meshfree method is employed to solve the governing equations. To achieve real-time performance, an octree data structure is used to organize the support sets and the nodes to expedite the computation in the meshfree method. The developed system brings together the surface representation for visualization and meshfree modeling for physically based animation to set up a virtual reality environment for soft tissue surgery simulation.
