OpenGL实现多场景

Weiler_Atherton的多边形裁剪算法-Weiler Polygon Clipping

OPENGL与四叉树完成地形的模拟,对三维GIS有很大的帮助!值得一看!-OpenGL and Quadtree completed terrain simulation and 3D GIS is a great help! An eye-catcher!

使用OpenGLES的库实现各种纹理特效，包括水纹，模糊等。The application demonstrates several effects using GLES functions.Such as Matt effect Focus blur, Uniform blur and so on.-The use of the library OpenGLES realize a variety of texture effects, including水纹, fuzzy, etc.. The application demonstrates several effects using GLES functions.Such as Matt effect Focus blur, Uniform blur and so on.

用鼠标实现opengGL程序的拾取功能，对球进行拾取，并有提示信息-Use the mouse to pick up procedures opengGL realize functions, to pick up the ball and has a message

GLUT 3.7 beta 图像数据分类 GLUT 3.7 beta image datafile distribution -GLUT 3.7 beta image data classification GLUT 3.7 beta image datafile distribution

绝对原创的鼠标控制代码 资源消耗量做到了绝对够小-Absolutely original code of the mouse to control consumption of resources to achieve a small enough absolute

（不是我原创的，但不记得从哪里下载的了）《openGL超级宝典》里面用到的库。可以做3D矩阵变换等。用途：openGL可以做矩阵变换，如平移、旋转、缩放，但是计算结果不能显式获取。使用math3d库可以计算一个向量经上述变换后的新坐标，并写入变量供程序的其他部分使用。

在下面的程序中，显示对一个网状球体的裁减-In the following procedure, showed a net reduction of the sphere

本代码实现将正方形的四个顶点分别映射到圆上，通过改变角度来控制旋转的快慢！从而在中间形成一个圆，但本代码未将多余的四角去掉,还有待完善的地方！

OpenGL程序,包括纹理映射,3维漫游等实现方法,编译后可直接运行.-OpenGL procedures, including texture mapping, three-dimensional method such as roaming, can be compiled to run.
