鋼彈模型

 -安裝opencv、GLUT

-把老師的bg.jpg、Diffuse.jpg下載並放在glut的bin裡面

-設定好codeblocks的compiler

利用老師網頁裡的範例 把diffuse的圖檔打開

-把剛剛放在glut/bin裡的jpg跟dll檔放到專案目錄裡 

-利用notepad++把檔案位置改成"."

-glm.c改檔名(cpp)>是

-gundam還沒切開.zip Diffuse.jpg,Gundam.obj,Gundam.mtl複製到專案目錄

-codeblocks重開，打開cbp檔，再add file(glm.cpp)

-右鍵transformation.c ,notepad++

-複製程式碼 

-編輯Diffuse.jpg (垂直翻轉)

-利用float angle喬角度

程式碼:
