摘要：
This paper studies the soft tissue deformation of Virtual Surgery Simulation, and using OpenGL to establish the virtual soft tissue deformation system based on mass-spring model. Discussed with fidelity and real-time of the soft tissue deformation in Virtual Surgery Simulation. By Comparing quadrilateral topology, the regular hexagon topology based on mass-spring model is proposed, discussed the dynamic model and its numerical integration method and force feedback calculation model of soft tissue deformation, according to the lack of nearest neighbor mass calculating algorithm in virtual surgical instrument contacting the soft tissue surface, a new method is proposed. The results show that, the modified algorithms have better stability and real-time in soft tissue deformation simulation.
