摘　　要：碰撞检测技术在织物的模拟等方面中有着广泛的应用。在采用质点-弹簧模型对柔性表面进行建模,对网格曲面进行三角划分后,为环境中的物体建立各自的方向包围盒(OBB)。用改进的碰撞检测和自碰撞检测算法对柔性织物及其所处三维空间中的物体进行处理,提高了柔性织物动态仿真的速度。The use of collision detection is wide in cloth simulation and other aspects. The mass-spring model is adopted to construct a piece of flexible cloth. After surface is divided into small triangles, oriented bounding boxes （OBB） is constructed for objects in 3D scene. The improved collision and self-collision detection algorithm between objects are used to increase the velocity of the real-time simulation for flexible cloth.
