Description: Polygon clipping is one of those humble tasks computers do all the time. It s a basic operation in creating graphic output of all kinds. There are several well-known polygon clipping algorithms, each having its strengths and weaknesses. The oldest one (from 1974) is called the Sutherland-Hodgman algorithm. In its basic form, it is relatively simple. It is also very efficient in two important cases, one being when the polygon is completely inside the boundaries, and the other when it s completely outside. Platform: |

Description: 多边形裁剪程序：用到的是比较常见的裁剪算法：Sutherland-Hodgman算法。本程序中的裁剪顺序为左边、下边、右边、上边，那么裁剪是这样进行的：原待裁剪多边形作为输入多边形被裁剪矩形的左边裁剪，然后输出的裁剪结果作为下边裁剪的输入多边形，……，依次类推，直到最后一边矩形上边裁剪结束。-Polygon clipping process: it is more commonly used method of cutting: Sutherland-Hodgman algorithm. This procedure of cutting the order for the left, bottom, right, top, then the cutting is carried out: the original clipping polygon to be clipped polygon as input the left side of the rectangular cutting, then cutting output cut as the bottom of the input polygon, ... ... , and so on, until the last end side of the rectangular cut above.

Description: 在定义了窗口之后，我们只需将窗口内的图形显示出来，对于窗口之外的图形我们是不关心的。因此，必须将窗口外的图形裁剪下去。在本资料中，实现如下对直线段进行裁剪的算法：Cohen-Sutherland算法、中点分割算法、梁友栋-Barsky算法，并且利用Sutherland-Hodgman算法实现对多边形的裁剪，最后，实现当裁剪域是任意凸多边形时的裁剪算法。-In the definition of the window, we simply window graphics are displayed, in addition to window graphics we are not concerned. Therefore, the need to cut down the graphics outside the window. In this data, to achieve the following sections of the cut line algorithm: Cohen-Sutherland algorithm, the mid-point division algorithm, Liangyou Dong-Barsky algorithm, and using Sutherland-Hodgman polygon clipping algorithm, and finally, to achieve when the cutting domain is arbitrary when the convex polygon clipping algorithm.
