Step01-1
用Maya裁切模型
每個部位分別存OBJ檔
Step01-2
下載Git 把Final_Project複製到桌面
開啟Final_Project調整設定
修改.gitignore
Step02-1
把glm.cpp glm.h丟到Final_Project資料夾裡
建model資料夾把剛剛裁切的模型丟進去
修改程式碼 把模型印出來
///week12-4_keyboard_mouse要用鍵盤滑鼠操控茶壺
///存檔會在工作執行目錄working dir
///在Codeblocks Project-Properties裡面的build targets可以設定
///把它從Desktop\freeglut\bin改成.(現在目錄的意思)DEBUG和Release都要設定才會將.cbp檔存檔
