讲述了软体采用层次包围盒方法进行碰撞检测时，针对连续变形包围盒树的两类
更新方法：静态更新和动态更新，对静态更新方法中的自上而下、自下而上和混合更新方法，动态更新方法中的离散法和连续法进行了分析，并利用实验数据比较了各种算法在不同仿真环境下的运算速度。结果显示，混合更新方法和连续法在虚拟现实环境中具有更好的性能。
关键词：包围盒更新方法；自上而下；自下而上；混合更新；运动包围盒层次结构
Abstract: When deformable collision detection used the Bounding Volume Hierarchies
approach, two kinds of strategy for updating hierarchy in order to handle continuously
deforming:static and dynamic approaches were described.Top-down,bottom-up and hybrid
updating approaches of static method,discrete and continuous approaches of dynamic method were analyzed.Experiment data was used to compare all these methods with their compute speed in different simulation environments.The results show that, the hybrid and continuous approaches have better performance than other approaches in virtual reality environments.
