Realization and Application of Mass-Spring Model in Haptic Rendering System for Virtual Reality

Deformable objects raise a complex combination of issues ranging from estimating mechanical parameters, solving large systems of differential equations, detecting collisions, modeling responses to collisions. Some issues in surgical simulation such as collision detection and feedback force computation still lack adequate solutions. To resolve these problems, we researched on the haptic rendering system for virtual reality and optimized the mass-spring model of deformable objects for surgical simulation. This paper introduces mass-spring model for deformable objects and the composition and applications of a haptic rendering system for virtual reality. The mass-spring models of human organs have been integrated into a haptic rendering system for virtual reality for surgical simulation. Based on the simulation results, the performances and the application prospects of the mass-spring model are analysed and discussed as conclusions.
