摘要
图形的裁剪与覆盖是计算机图形学中较为热点研究的问题，作者对此进行了深入的研究与实践，提出了较为理想的圆形窗口“裁剪与覆盖”的计算机辅助设计新算法。该算法利用计算机最简单的右移一位来取代原算法中大量的乘除运算，从而加快了图形裁剪与覆盖的速度，提高了计算机进行图形处理的能力。
Graphics clipping and covering is one of the key points in computer graphics field. After more study and practice, a new algorithm is give,which is for clipping and covering in circular window. Adopting shifting principle to do multiply and division operation, we have got a more speed in clipping and covering,raised the capability of computer in graphics processing.
