Abstract: The most existing two dimension clipping algorithms are to lines and polygons. However, few people study the arc clipping algorithms. This paper studies the arc clipping algorithms. The basic principle of the algorithms is to apply envelopment box technology, then, the arc will be quickly clipped and judged in or out the clipping window.

摘要： 现有的二维裁剪算法大部分是针对直线与多边形进行的,很少有人对圆弧的裁剪算法进行研究。因此,该文研究了圆弧的裁剪算法,其基本思想是应用包围盒技术先将圆弧包裹起来再对圆弧进行快速判断和裁剪。
