1. 安裝3D Exploration (3D檔案總管)
4. 匯出OpenGL Sample APP → File-Save-As 選Cpp Open GL
5. 勾匯出Export Dialog出現框框選Sample APP
7. 把原本的main.cpp刪掉
8. Add File
9.選取剛匯出OpenGL Sample APP的檔案
10.試著執行 → 無法執行 → 將兩行過舊的程式注解掉
11.即可出現執行畫面
12. 利用老師的檔案myGLMsample.zip
內含data.zip、source.zip等裡的04160011_hw1.cbp加到CodeBlocks內
作業二:
1.將海豚個別儲存成obj檔
2.讓三隻海豚組成一個模型
程式碼:

#include <stdlib.h>
#include <GL/glut.h>
