| 摘 要： | 已有的线剪裁算法大都是针对矩形窗口或凸多边形窗口的,对于任意多边形窗口的线剪裁,目前尚无有效的算法,而这样的算法却有更普遍的应用意义.提出了一个多边形裁剪线段的有效算法,该算法运算高效、稳定.

| Abstract: | Existing line clipping algorithms are almost offered based on a rectangular window or a convex polygonal window.No efficient algorithm for line clipping against a generalized polygon is available in the literature.It is quite valuable to develop such algorithm.In this paper,an efficient algorithm against a generalized polygon is presented,and it can be proved the high efficiency and stability. |
