说明：  OpenGL函数查询手册，里面包括了所有gl,glu函数（我使用的时候发现有几个比较不常用的函数它没有包含进去）。至于glut函数，它没有录入，这是个遗憾的地方。不过你可以下载《OpenGL函数与范例解析手册》，它里边包含了gl,glu,glut的所有函数。推荐
(Query OpenGL function manual, which includes all gl, glu function [I use when found to have a few less commonly used functions to include it did not]. As glut function, it has no input, this is regrettable. But you can download " OpenGL analytic function and an example of the manual," which inside contains gl, glu, glut of all function. Recommend)
