摘要
提出了采用双链表翼边结构表示三维形体的几何信息和拓扑信息，运用ｄｏｏ－Ｓａｂｉｎ的双二次Ｂｅｚｉｅｒ曲面递归生成法及圆弧倒角法，实现空间立体的光滑倒角切削，并给出了运用该方法得到的实例．
The present author advances a method that can implement smooth solid chamfering by both applying doubly linked list wing side structure to express geometrical and topological information of 3D solid, and using doo Sabin doubly quadratic Bezier curved surface recursive generation and circular arc chamfering. An example obtained by this method is presented.
