伞状的

Part 4 is the round umbrella shape gear wheel, fixedly connect with part 3, rotate with one heart. 部件4为园伞形齿轮，与部件3固定连接，同心转动。

Topologic reconstruction method gets the optimized meshes by reconstructing the umbrella shape of every point and deleting antipathic triangles.This method has wide applied range and quick speed. 点集拓扑重建算法是采用局部构造的思想，对每一个点构造它周围的伞形，最后得到整体的三角网格，并对网格中的不相容三角形进行删除，最后得到优化的三角网格，该算法适用范围广，并且速度较快。
