GLUT視窗程式:

#include <GL/glut.h>

void display()

{

    glClearColor(1,0,0,0);//標示背景顏色(RGBA)

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);//清背景

    glColor3f(0,1,1);//設定前景顏色

    //glutSolidTeapot(0.3);//設定形狀:茶壺

    glBegin(GL_POLYGON);//開始畫(多邊形)

    glVertex3f(0,-1,0);//設定頂點:vertex

    glVertex3f(1,1,0);

    glVertex3f(-1,1,0);

    glEnd();//結束

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("GLUT Shapes");//影像視窗

    glutDisplayFunc(display);

    glutMainLoop();//執行迴圈

}
