Description: This the third tutorial in the Foundation section. This tutorial covers the basics of drawing some simple 2D polygons such as triangle, pentagon, rectangle etc. We will make use of the code that we had generated in the previous section. We ll cover some important topics such as Clipping Area, Viewports, Vertex and the Primitives in OpenGL such as the point, line, triangle, polygon, quads etc. We ll write a program that is menu driven and draws points, triangles, lines, quads etc. Platform: |

Description: 了解二维图形裁剪的原理（点的裁剪、直线的裁剪、多边形的裁剪），利用VC+OpenGL实现直线的裁剪算法。
2．实验内容：
（1） 理解直线裁剪的原理（Cohen-Surtherland算法、梁友栋算法）
（2） 利用VC+OpenGL实现直线的编码裁剪算法，在屏幕上用一个封闭矩形裁剪任意一条直线。
（3） 调试、编译、修改程序
-Understanding of the principles of cutting two-dimensional graphics (point of cutting, cutting a straight line, polygon clipping), the use of VC+ OpenGL to achieve a straight line cutting algorithm. 2. Experimental contents: (1) understand the principles of cutting a straight line (Cohen-Surtherland algorithm, You-Xin Liang Dong algorithm) (2) the use of VC+ OpenGL to achieve a straight line cutting the coding algorithm, on the screen in a closed arbitrary rectangular cutting a straight line. (3) debug, compile, modify the program Platform: |
