Week 13

到Maya把模型分割身體部位，然後把上周的Final Project打開

到project----->到properities----->到右下角的Build Option----->到Search directories把complier跟linker的目錄改成feeeglut\include就好

之後把第十周的glm.h 跟glm .cpp放到目錄下，然後把剛剛裁切的身體obj檔創一個

資料夾也放到目錄下

記得freeglut跟freeglut.dll都要放進專案裡

去把.gitignore裡面的lib 、.a、obj、還有.dll前面加個井號這樣上傳才不會被捨棄掉

之後專案加上glm.cpp就可以了

#include <GL/glut.h>
