1)Cohen-Sutherland算法; 2)梁有栋-Barsky算法; 3)Nicholl-Lee-Nicholl算法; 有的文献会通过对象与观察体的位置,严格区分裁剪(clipping)与剔除(culling). 裁剪,指对象与观察体边界相交;剔除,指对象完全位于观察体外. Cohen-Sutherland线段裁剪算法 基本思想 裁剪窗口对应的正则矩形区域,按边界将平面划分为9部分,每个...

其中比较著名的有:Cohen-Sutherland算法、中点分割算法、Liang-Barsky算法、Sobkow-Pospisil-Yang算法,及Nicholl-Lee-Ncholl算法等。 2 直线裁剪的基本原理 图1所示的为直线与窗口边界之间可能出现的几种关系。可以通过检查直线的两个端点是否在窗口之确定如何对此直线裁剪。如果一直线的两个端点均在窗口边界之(如图1中...
摘要:直线裁剪是计算机图形学中的一个重要技术,在对常见的直经线裁剪的算法分析的基础上,针对Cohen-Sutherland算法和Liang-Barsky算法进行了分析研究。并对两种算法了计算直线与窗口边界的交点时,进行了有效有比较。 关键词:裁剪;算法;Cohen-Sutherland;Liang-Barsky; ...
