摘　　要：在布料仿真中,碰撞检测与响应十分复杂,很难同时具备真实感和实时性。针对此问题,采用质点弹簧模型进行建模,基于FDH包围盒提出一种快速的检测基本几何元素间碰撞的方法。通过分析点的位置向量与三角平面的夹角,利用向量内积的性质来判断点与三角形的位置关系,同时进行了相应的碰撞响应处理。实验结果表明,采用该方法进行碰撞检测既保证了模拟的真实性,同时又提高了系统的实时性。In dynamic cloth simulation, collision detection and response are complicated, so that it is ditl＇icuh to achieve both the realistic and the real-time. To solve this problem, we adopted the mass-spring model for cloth, and then an effective method was proposed to detect the intersection of mass and triangle accurately based on the FDH bounding boxes. The collision response is considered respectively. The experimental results demonstrate that this method is efficient and robust.
