关于OpenGL（含ES）的资料汗牛充栋，但是普遍存在的问题是，OES的资料不够系统，OGL的资料过于庞大
此列表详细记录了GLES2兼容函数的情况，使大家在学习时，对于算法和资料可以有针对性的选择
此列表来自Qt的QOpenGLFunctions类，该类用于创建OpenGL和OpenGL ES兼容项目（在一个工程里）
注：Qt支持各种版本的GL头文件导入，命名方式为QOpenGLFunctions_X_Y，对于更高级的3+桌面版，使用例如QOpenGLFunctions_3_0这种类
很多人对这个表怎么用，不是很清楚，这里再补充一下，目前跨平台OpenGL开发（桌面＋移动 ）主流API选择是OpenGL ES 2。这个表纪录了OpenGL ES2所有函数的兼容情况。如果你是走这个方向的，这个表很有用。
网上资料，很多都是OpenGL ES 1或者还有立即模式那种很古老的API，那些都是淘汰的。对于新手来说，你把那些资料里面，出现的gl打头的函数在这个表里搜索一下，如果是 这个表里没有的，基本上那份资料就可以不用看了。（不过你得注意一些工具库比如glm，glew，glut，别认错了）
补充一份：详细的OpenGL（ES）各版本API差别在这里：http://docs.gl/
