| 摘 要： | 本文在已有多边形裁剪算法的研究基础之上，提出了包含圆弧段的复杂多边型裁剪方法。该方法中的被剪切对象是较为复杂的几何实体，包括圆弧以及带有圆弧边界和带有洞的复杂多边形对象，其中剪裁窗口可以为凹多边形或凸多边形。

| Abstract: | On the basis of the existing algorithm of cutting polygon, the cutting method is developed of complicacy polygon including arc. The cutting object is complicacy geometry entity, which is complicacy polygon with arc ,arc boundary and hole, the cutting window can be cave or convex polygon. |
