(1)茶壺打光

 

 

#include <GL/glut.h>

void display()
{
    GLfloat pos[]={0,0,-1,0};
    glLightfv(GL_LIGHT0,GL_POSITION,pos);
    glEnable(GL_LIGHT0);

    glutMainLoop();

}

 

(2)T-R-T 茶壺旋轉

 

#include <GL/glut.h>

    glPushMatrix();

        glTranslatef(0.6, 0.2, 0); ///最後一步,把樓下的 "會對壺柄做旋轉的東西" 再移到右上 掛上去 ver4
        glRotatef(angle,0,0,1); ///把下面整團都對中間做旋轉 ver3
        glTranslatef(0.3, 0, 0); ///把它往右移,壺柄在中間 ver2
        glutSolidTeapot(0.3); ///這是個茶壺 ver1
    glPopMatrix();

    glutSolidTeapot(0.3); ///body

    glFlush();
