T移動、R轉動，右鍵 swap交換T R

```cpp

glTransslatef(0..9,0.0,0.0); //移右邊

glRotatef(角度,0,1,0); //轉動

```

2.

```cpp

glpushMatrix();

    glRotatef(angle,0,0,1);

    myDrawObject(1);//畫手臂

glPopMatrix();

```

step02

```cpp

glpushMatrix();

    myDrawObject(0);//畫身體

    glRotatef(angle,0,0,1);

    glTranslatef(-0.3,-0.19,0);//往左下移

    myDrawObject(1);//畫手臂

glPopMatrix();

```

```cpp

glpushMatrix();

    myDrawObject(0);//畫身體

    glTranslatef(0.29,0.31,0);//往右上移

    glRotatef(angle,0,0,1);

    glTranslatef(-0.3,-0.19,0);//往左下移

    myDrawObject(1);//畫手臂

glPopMatrix();

```

2.

```cpp

glpushMatrix();

    glTranslatef(0.29,0.31,0);//往右上移

    glRotatef(-45,0,0,1);

    glTranslatef(-0.8,0.9,0);

    glTranslatef(-0.8,0.9,0);;

    drawHand();
