%     基于包围体树的碰撞检测算法， 一般首先都会初始化环境然后构建层次结构的包围体树，碰撞检测时从顶层开始逐渐往下层遍历，到最底层叶子节点后开始三角网格模型相交测试，
%     当发现三角网格相交后立即终止遍历，确定模型发生碰撞。
%     评价碰撞检测算法的指标一般用上面这个公式来衡量，其中nv和 np分别表示参与包围体节点相交测试的数量和参与原始几何相交测试的数量，Cv和 Cp则表示相应的平均测试耗费的代价。
%     当在运动场景时还需要加上nu和 Cn就是模型旋转或者运动后包围体更新的数量和更新的代价。
%     本文算法就是尽早发现包围体不相交的情况，减少np和cp的数量。
