This is a heuristic strategy. it can reduce the intersection tests need to be computed between bounding volumes by tracing the traverse process in previous time to gain traverse path in current time. the correctness and validity of collision detection can be guaranteed by maintaining the tracing list
這是一個啟發式的策略，通過跟蹤國防科學技術大學研究生院學位論文上一時間采樣點對包圍盒樹的遍歷過程，確定當前時間采樣點的遍歷路徑，從而有效地減少了遍歷過程中包圍盒相交測試的次數，提高了演算法效率，同時通過對跟蹤表的維護，保證了碰撞檢測的正確性和有效性。 -
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。 -
Based on researching and developing intrinsic character of fixed direction hulls, this paper develops and proves the property which make it can be apply to collision detection in complex environment and resolves the problems about intersection tests between bounding volumes, updating bounding volumes after rotation and updating bounding volume hierarchy after deformation
本文在充分研究了固定方向凸包的固有特性的基礎上，開發並證明了它適用於復雜環境中軟體碰撞檢測的性質，並著重解決了包圍盒間的相交測試、對象運動后包圍盒的更新、對象變形后包圍盒樹的更新等問題。 -
So, with the help of the divisional envelope pitch, lots of unnecessary detection of triangles intersection wo n ' t be carried out. and it speed the process of model simplification
與cohen的演算法相比，採用分解式包絡片來控制模型簡化誤差后，可以節省很多不必要的三角形相交判斷，大大加快了包絡構造和模型簡化的速度。 -
Workspace are obtained by monte carlo method, this paper combines aabb bounding box and judge of points of intersection for collision detection between static obstacle and robot arms, by " expanding " obstacles, it is done by judge of distance and inclusion test
將障礙物「膨脹」 ，再通過端點距離判斷和包含性測試，實現了機械臂與靜態障礙物的碰撞檢測，通過搜索局部最優化路徑點的方法實現了自動障礙規避。
