第一个openGL程序（输出一个白色矩形）#include//需要包含头文件#include ，这是GLUT的头文件void Display(void)//以gl开头的都是OPengL的标准函数{glClear(GL_COLOR_BUFFER_BIT);//GL_COLOR_BUFFER_BIT表示清除颜色，glClear函数还可以清除其它的东西glRectf(-0.5f,

#includevoid Display(void){glClear(GL_COLOR_BUFFER_BIT);glBegin(GL_POINTS);/*glBegin支持的方式除了GL_POINTS和GL_LINES，还有GL_LINE_STRIP，GL_LINE_LOOP，GL_TRIANGLES，GL_TRIANGLE_STRIP，GL_TRIANGLE_FAN
