This article proposes in order to quickly hidden processing is carried on to multi concavo - convex polyhedron , the hierarchical structure is applied to carried on description on topo relations of three dimensional physique ; the bidirectional link table is applied to carried on the dynamic node assignment , for enhancing the efficiency of the algorithm ; when multi three - dimensional body is being hidden processing , the screen projection polygon should be carried on the overlaped eliminating confirmation and the polygon edges be carried on the computation of the intersectant points , the depth inspection , the comprehensive test and so on
摘要文章提出一种对多个凹凸形多面体进行消隐处理算法，并介绍了采用层次结构进行三维形体的拓扑关系描述；采用双向链表进行动态结点分配的算法，提高了算法效率；对多个三维物体消隐处理时，进行屏幕投影多边形的重叠排除验证，对多边形边进行交点计算，深度检查，包容性测试等。
