Abstract

Abstract: This paper presents a skeleton-based hybrid method on deformable object modeling which can be used in virtual surgery simulation and surgery training. It introduces an automatic approach to extract the skeleton of deformable objects and the process of creating the surface physical model, the volume physical model and their corresponding computational model. The collision detection method using skeleton and external force calculation is also described. Meanwhile, the architecture of the experimental software and the result of experiment are provided.

Key words: Modeling, Deformable object, Surgery simulation
