Abstract :
In this paper, the collision detection and response that based on the OBB (oriented bounding boxes) tree structure was realized in virtual surgery simulation system for nasopharyngeal carcinoma. The point of contact location and the vector of contact surface can be acquired. The force effect in virtual surgery simulation was improved. A twice detection method was proposed to improve the phenomenon of the force puncture, and a synchronize mechanism was adopt to improve the stability of the force output. Simulation results show that the improved algorithm has been enhanced in the force puncture and stability of the force, and the force effect is more authentic.
