Introduction 对于Cohen-Sutherland 算法函数接口为: void ClipLine(Line line, Rect window); line:(x0,y0,x1,y1):被裁剪直线。 window:(bp,ep,width,height):裁剪窗口。 算法步骤 裁剪的实质就是决定图形中哪些点、线段、文字、以及多边形在裁剪窗口之内: Cohen-Sutherland算法有时也称为编码算法,该算法分为三...

Cohen–Sutherland是一个线段裁剪算法 原理 将窗口区域分为9个部分,每个部分给一个区域码,然后计算线段两端端点的区域码,根据区域码来选择抛弃线段 Paste_Image.png 两端点都在视口区域内,区域码相或为0,接受 两端点至少共享一个不可见区域,区域码相与不为1,拒绝 实现 typedefintOutCode;constintINSIDE=0;// 0000...
Partially inside the window : Both endpoints are in different regions. In this case, the algorithm finds one of the two points that is outside the rectangular region. The intersection of the line from outside point and rectangular window becomes new corner point and the algorithm repeats...

There exist total 26 possible cases for trivial rejection of a line. Out of these 26 cases only 12 cases were solved without dividing the line into segments in the Cohen-Sutherland line clipping algorithm. Remaining 14 cases were solved by dividing the line into segments. But if the line is...
