| 摘 要： | 已有的多边形裁剪算法都是针对矩形窗口或凸多边形窗口进行的。但是，在实际应用中，也常常使用圆形窗口对多边形区域进行裁剪和填充。因此，本文提出一个对干圆形窗口的凸多边形区域裁剪法，并且给出作出凸多边形Ｐ在窗口Ｖ之内部分的定理。

| Abstract: | Existing polygon clipping algorithms are all offered for a rectangular window or a convex polygonal window. But polygon clipping and tilling against a circle is often required in practical use. In this paper, a convex polygon clipping algorithm based on a circle is presented. A theorem about a convex polygon P within 1
a circular window V is also given. |
