| 摘 要： | 提出了一种新颖而实用的圆形窗口Ｖ对多边形Ｐ的裁剪算法。它将多边形Ｐ的边视为有向线段，通过引入多边形顶点的入边和出边交点的概念，深入研究了Ｐ被Ｖ裁剪后的区域确定问题，给出了作出Ｐ在Ｖ内部分的定理

| Abstract: | A simple and practical clipping algorithms for a polygon P is offered based on a circular window V. It considers the edges of the polygon as directed lines, and studies the problem of deciding the area edge of P clipping by V, based on the intersection point concept of in edges and out edges of the polygon vertices. The theorems about what is the inner part of the polygon P within a circular window V are presented. |
