A physical based meshless method for soft tissue deforming

Abstract

This paper concentrated on how to apply meshless method to do physical based soft tissue deformation. First we approximated the deformation field using a Moving Least Squares (MLS) approximation method. Then, a compact force computation was applied to accelerate the physical computation speed. Finally we implemented a surface animation method to simulate the deformation of soft tissue under external forces. We made experiments with real properties of human soft tissue and the results showed that our method successfully made physical based deformation of human soft tissue.
