一个OpenGL小程序

发个没什么技术含量的文，最近准备通过opengl的学习来好好c++，于是找了网上的教程来搭建opengl的编写环境，建了个空项目，又找了个案例稍微改了改运行了下，还成，ok了~喜不自禁~

贴个图：

代码如下：

#include <windows.h>
#include <GL/glut.h>
#include <stdio.h>
#include <stdlib.h>
#include <math.h>

void renderScene(void)
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glLoadIdentity();

glBegin(GL_TRIANGLES);

glVertex3f(-0.5,-0.5,0.0);

glVertex3f(0.5,0.0,0.0);

glVertex3f(0.0,0.5,0.0);

glEnd();

glutSwapBuffers();
}

void main(int argc,char*argv[])
{
    glutInit(&argc,argv);

glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);

glutInitWindowPosition(100,100);

glutInitWindowSize(320,320);

glutCreateWindow("Hello OpenGL");

glutDisplayFunc(renderScene);

glutMainLoop();//enters the GLUT event processing loop.

}
