【摘要】 提出了一种计算两凸多面体间最短距离的算法.该算法用物体三维空间顶点坐标的凸包表示凸多面体,采用非线性规划方法来计算两凸多面体间最短距离,并通过最短距离来判断两凸多面体是否发生碰撞.实例证明这种方法的有效性.

【Abstract】 An algorithm for computing the minimum distance between two convex polyhedra is presented.The algorithm is applied to polyhedral objects which can be represented as convex hulls of its value of vertices in three-dimensional space.Nonlinear programming techniques are then employed to computer the minimum distance between two convex polyhedra,and according to the minimum distance,it can be concluded whether or not the objects will collide.The algorithm of collision detecting presented in this paper improves the efficiency of collision detecting by simulation experiences.
