在vs2010里使用opengl

确切的说opengl已经包括在vc2010里面了、所以无需任何的安装、只要输入相应的库文件和头文件便可以了、下面是个简单的示例、

使用vc2010新建一个win32程序、下一步里选择新建空工程项目、然后再在Source Files里添加一个cpp文件、输入以下的内容、

前两行是引入opengl的两个库文件、然后是引入两个gl的头文件

#pragma comment(lib, "opengl32.lib")
#pragma comment(lib, "glu32.lib")


#include <windows.h>
#include <gl/gl.h>
