Study on simulation technology applied in virtual surgery of peritoneal membrane

Based on physical properties of peritoneal membrane tissue, Mass Spring Model, which is fit for simulating the deformation of peritoneal membrane tissue in virtual surgery, is built in the paper. Then three numerical solution methods of this model are compared and analyzed to furthur put forward another simulating and modeling method, which is more reasonable and reliable. Also, problems of new model´s collision detection and collision response are raised. The model is solved by quasi-static method to get steadier and more realistic simulating effect of deformation, and then to lay the foundation for furthur simulation of peritoneal membrane´s virtual surgery.
