                                 電腦圖學

先把程式碼弄上來

void timer(int t)

{

    glClearColor(1,0,0,0);

    display();

}

int diff=2;

void timer(int t)///鬧鐘響了,timer叫了

{

    glutTimerFunc(30,timer,t+1);

    angle+=diff;

    if(angle>180) diff=-diff;

    if(angle<0) diff=-diff;

    display();

}

void drawArm1(){

    glPushMatrix();

        glScalef(1,0.5,0.5);

        glColor3f(1,0,0);glutSolidCube(0.3);

    glPopMatrix();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

     glColor3f(1,1,1);glutSolidCube(0.4);

     glPushMatrix();

        glTranslatef(-0.2,+0.2,0);

        glRotatef(angle,0,0,1);

        drawArm1();

    glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}
