给出了其自相交局部时平方可积和联合连续的一个充分条件，并通过对广义α-stable过程自相交局部时的H？

Based on the limitations of OBB, this thesis proposes an optimizing overlap test algorithm of bounding box and primitive. This method eliminates the bounding boxes of leaf nodes and streamlines the OBB hierarchical layer. This method also introduces a separating axis theory in the overlapping test between the primitives in order to accelerate the velocity.

针对基于OBB碰撞检测算法存在的缺陷，研究利用包围盒与基本几何元素相交测试的优化方法，消除叶子结点包围盒，精简OBB层次结构；同时在基本几何元素相交测试中引入类似分离轴的方法，加快检测速度。

It respectively constructs quasi projection-separation facet sets of two convex polytopes while their orthogonal projection on the centerline overlap mutually. Afterward it judges the separation of two convex polytopes by confirming non-overlap in orthographic projection on the centerline or by finding out a projection-separation facet from two quasi projection-separation facet sets, otherwise a collision is judged.

该算法通过判断2个凸多面体在中心线上的正投影不相交，或者分别构造它们的准投影分离面集合，并从这2个集合中找到一个投影分离面，来判断2个凸多面体分离；否则，判断为相交。
