Real-time simulation of tissue cutting based on improved mass-spring model

Surgical simulations are highly desired nowadays, since those can help surgeon trainees to practice and evaluate their surgical skills. A key element for the surgical simulation is the ability to simulate it realistic and real-time. In this paper, an effective method is proposed to achieve the realistic simulation of tissue cutting, and it is also real-time which is important to us. The method is based on an improved mass-spring model: a ldquovirtualrdquo spring is firstly introduced to ensure the realistic and real-time of the simulation, and a classic computation geometry algorithm is used to solve the problem of cutting detection, besides, the utilization of the verlet integration strengthens the real-time of the simulation as well.
