Prune away the extraneous stuff and get to the heart of the matter. clarity of thought leads naturally to clarity of communication, which in turn leads to major progress
桔解：清除掉外來多餘信息，直達事情的主要中心。清晰的思路自然能進行清晰的溝通，從而達到最主要的進程。 -
The idea behind it is to approximate the object with a simpler bounding volume that is a little bigger than the object. in building hierarchies on object, one can obtain increasingly more accurate approximations of the objects. so during traversing bounding volume hierarchy, it speeds up collision detection by prune away primitive pairs, which will not intersect clearly though rapid intersection test between bounding volumes and just deal with those whose bounding volume is intersected
層次包圍盒方法是解決碰撞檢測問題固有時間復雜性的一種有效的方法，它是用體積略大而幾何特性簡單的包圍盒來近似地描述復雜的幾何對象，並通過構造樹狀層次結構來逼近對象的幾何模型，從而在對包圍盒樹進行遍歷的過程中，通過包圍盒間的快速相交測試來及早地排除明顯不可能相交的基本幾何元素對，而只對包圍盒重疊的部分元素進行進一步的相交測試，以提高碰撞檢測的速度。
