Visual Studio 2008中OpenGL的安装配置【转载】

#include <stdio.h>
#include <windows.h>
#include <gl/glut.h>
 
int main(int argc, char** argv)
{
glutInit(&argc,argv);
//显示模式初始化
glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB|GLUT_DEPTH);
//定义窗口大小
glutInitWindowSize(300,300);
//定义窗口位置
glutInitWindowPosition(100,100);
//创建窗口
glutCreateWindow("testgl");
const char* version = (const char*)glGetString(GL_VERSION);
printf("OpenGL 版本：%s\n", version);
glutMainLoop();
return 0;
}

下面的程序是利用OpenGL画公式 $f(x)=\exp(-x)\cos(2\pi x)$ 的曲线:
