GLEW是一个跨平台的C++扩展库，基于OpenGL图形接口。使用OpenGL的朋友都知道，window目前只支持OpenGL1.1的涵数，但 OpenGL现在都发展到2.0以上了，要使用这些OpenGL的高级特性，就必须下载最新的扩展，另外，不同的显卡公司，也会发布一些只有自家显卡才支 持的扩展函数，你要想用这数涵数，不得不去寻找最新的glext.h,有了GLEW扩展库，你就再也不用为找不到函数的接口而烦恼，因为GLEW能自动识 别你的平台所支持的全部OpenGL高级扩展涵数。也就是说，只要包含一个glew.h头文件，你就能使用gl,glu,glext,wgl,glx的全 部函数。GLEW支持目前流行的各种操作系统（including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris）。

这是最新版本 1.90-The GLEW extensive library is a cross-platform C++ based on the OpenGL graphics interface. Know friends using OpenGL window is currently only to support OpenGL1.1 culvert number, but OpenGL development to more than 2.0, you must download the latest extension to use these advanced features of OpenGL, different graphics company, will publish only their own graphics only support extension functions, in order to use the number of Han had to go looking for the latest glext.h With GLEW extension library, you no longer have to find the function interface The worry because GLEW your platform supports all OpenGL can automatically identify the number of senior extension Han. That is, as long as contains a glew.h header file, you can use all the functions gl, glu, glext, wgl, glx. GLEW support the current popular variety of operating systems (including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris). This is the latest version 1.90
