WEEK11  課堂der筆記筆記 

課堂作業1~~~足球

1.搜尋3D Exploration下載程式，解壓至桌面並完成安裝

  http://www.freespacemods.net/e107_plugins/download/download.php?view.129

2.至老師的網頁下載data檔，解壓至桌面

  http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/

3.執行3D Exploration程式，找到剛剛data路徑，查看模型

4.按照下徒步驟，把足球模型另存成cpp

5.開啟CodeBlocks，新增一個OpenGl專案

6.將原本main裡面的程式刪除

7.新增足球程式

8.測試執行失敗，將錯誤此兩行程式刪除

9.執行程式碼結果

課堂作業1~~~海豚

1.使用3D Exploration，將三隻海豚分別輸出

2.照下圖所示另存，重複相同步驟三次(dolph1、dolph2、dolph3)

3.開起老師給的檔案myGLMsample、freeglut
4.將剛剛存的三個海豚檔拉至myGLMsample的data裡
