我是第12周
一開始老師先教.cbp檔用codeblocks開的方式，首先去載source、win32、freeglut(要複製改32)，之後到codeblocks的enviroment裡把這個打勾
打勾完後所有資料就可以直接用codeblocks開了
接下來這裡很重要:
先開一個glut專案檔
開完了之後把glm.c改成glm.cpp然後跟glm.h一起丟到專案檔底下
接下來進codeblocks在這裡按add files
然後選glm.cpp
開啟了不要動glm.cpp
在main的程式碼裡
寫上之前匯obj檔的程式碼
再來要把資料都集中到專案資料夾裡
所以要先把freeglut.dill丟到專案底下
再改路徑
先把這個用notepad++開起來
再把路徑改成小數點如下圖
好了以後就可以把obj跟mtl丟到專案底下了
再來再來老師教怎麼匯入多個模型
