Collision detection and response of dynamic cloth simulation in virtual environment

Due to collision detection and response is very time-consuming, the real-time and lively effect was difficult to achieve in dynamic cloth animation. The mass-spring model for dynamic cloth was adopted, and then based on bounding boxes hierarchy, a collision detection algorithm was given and an algorithm converted self-collision detection was proposed into collision detection. In order to enhance the collision detection speed of basic geometrical units, an improved method was proposed to detect the intersection of mass and triangle accurately, and then a collision response process was described according to mechanics principle. Experiment results show that those approaches improve real-time and vivid effect.
