1. 把茶壺加上顏色
#include <gl/glut.h>
void play()
{
    glutWireTeapot(0.3);
    glColor3f(1,1,0);     //加上黃色

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

    glutCreateWindow("02163015江世光");
    glutDisplayFunc(play);
    glutMainLoop();
    return 0;
}

2. 加上不同大小的茶壺
#include <gl/glut.h>
void play()
{
    glutWireTeapot(0.3); //邊長最大茶壺
    glColor3f(1,0,0);     //加上紅色
    glutWireTeapot(0.2);//邊長中等茶壺
    glColor3f(0,1,0);//加上綠色
    glutWireTeapot(0.1);//邊長最小茶壺
    glColor3f(0,0,1);//加上藍色
    glFlush();
}
int main(int argc,char *argv[])
{
    glutInit(&argc,argv);

    glutCreateWindow("02163015江世光");
    glutDisplayFunc(play);
    glutMainLoop();
    return 0;

3.加上一個背景顏色#include <gl/glut.h>void play(){    glClearColor(0.5,0.4,0.9,0.8); //加入清理顏色    glClear(GL_COLOR_BUFFER_BIT);  //要清理BUFFER_選擇    glutWireTeapot(0.3);     glColor3f(1,0,0);       glutWireTeapot(0.2);    glColor3f(0,1,0);    glutWireTeapot(0.1);    glColor3f(0,0,1);    glFlush();}int main(int argc,char *argv[]){    glutInit(&argc,argv);
    glutCreateWindow("02163015江世光");    glutDisplayFunc(play);    glutMainLoop();    return 0;}

4.自己畫一個形狀

#include <gl/glut.h>

void play()

{

    glClearColor(0.5,0.4,0.9,0.8); //加入清理顏色

    glClear(GL_COLOR_BUFFER_BIT);  //要清理BUFFER_選擇

    glBegin(GL_POLYGON);

        glColor3f(1,1,1);

        glVertex2f(0,0);

        glVertex2f(1,0);

        glVertex2f(0,1);

    glEnd();

    glBegin(GL_POLYGON);

        glColor3f(1,0,0);

        glVertex2f(0,0);

        glColor3f(0,1,0);

        glVertex2f(-1,0);

        glColor3f(0,0,1);

        glVertex2f(0,-1);

    glEnd();

    glFlush();

}

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

{

    glutInit(&argc,argv);

    glutCreateWindow("02163015江世光");

    glutDisplayFunc(play);

    glutMainLoop();

    return 0;
