 1-1  https://jsyeh.org/3dcg10/下載win32和data並且解壓縮這兩個檔，
        執行Transformation.exe(切換swap T R)讓車子看起來在旋轉
        

       
       看起來好像放在右邊有個轉動的車子
        glTranslateef(0.8,0,0);在右邊
        glRotatef(angle,0,1,0);轉動
      
       看起來好像車子再在繞著中心點轉彎
       glRotatef(angle,0,1,0);
       glTranslatef(0.00,0.0,0.0);

      點ToDraw開始畫圖

    (1) myDrawObject(0);移動到下面glTranslatef(0,0,0);

    

  (2)點擊右上角的angle，並按下空白鍵，圖形就會進行旋轉

    

(3) myDrawObject(0);移動到glTranslatef(0,0,0)，點glTranslatef(0,0,0);就可以拖曳移動圖形位置
