By constructing the list of vertices of polygon and intersecting points between polygon and rectangle , the list of vertices of rectangle and between polygon and rectangle , the list of incoming points and the list of outcoming points , the problem that how to confirm close clipped area edge is solved . at the same time , the second encoding technology is developed from line clipping to polygon clipping so that the speed of algorithm is increased
矩形窗口多边形裁剪的改进算法通过引入多交表、矩交表、入点表、出点表等线性链表，解决了如何确定一般多边形在矩形窗口裁剪后封闭区域边界问题，并把二次编码技术由线裁剪拓展到多边形裁剪中，对处于窗外的多边形的边可直接处理，提高了算法的效率。
