1.先下載老師給的data,win32,glut32.dll
http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
2..將window.zip解壓縮到window資料夾，複製glut32.dll到window資料夾裡
並打開Light Material.exe執行檔
(可以按右鍵改變圖案)
3.先開啟freeglut windows網站然後下載
Download freeglut 3.0.0 for MinGW
然後解壓縮然後打開lib資料夾，複
製貼上libfreeglut.a，把複製的改名為libglut32.a
4.打開codeblack先建一個glut然後開啟執行
5.按 - 可以讓它變尖 ， 按 + 可以讓它變圓
→把茶壺打光←
7.先把本來的程式碼複製到記事本(等等需要用到)
然後刪掉程式碼
8.把之前水壺的程式碼複製貼上
9.然後把本來的程式碼的其中兩段複製貼上
