咻碰閃week13

 week13

1-1 先安裝git，下載上週Final_project，開啟上週專案，將絕對路徑改成相對路徑，之後不用再裝freeglut

1-2 freeglut移到專案資料夾裡，打開.gitignore註解掉.dll、.a、.lib(加#)

都設定好後檔案執行成功

2-1 https://jsyeh.org/3dcg10/ 下載data 在Maya匯入al.obj

2-2 裁切頭、身體、手臂、腳，分開匯出，放進新資料夾model裡

2-3 複製第10週 glm.h、glm.cpp檔至Final_project

新增glm.cpp到專案裡

2-4 修改程式碼
