DTang---week13_綜合練習

 week13 - 裁切模型

使用Maya匯入模型後，就需要的肢體部位做分段儲存(使用OBjproject檔)

附註：上課時暫用老師帳號，回家要自己申請帳號

(被切到剩這樣了www)

一共切出這些

Final_Project

feeglut工作目錄不對等的情況的處理

專案==> properties ==> project setting ==> project's build options ==> ...... ==>  C:\Users\Administrator\Desktop\freeglut\include ==> freeglut\include

目錄也要注意，工作執行目錄下必須要放freeglut.dll

讀取obj檔，記得先加入glm.cpp 跟 glm.h兩個檔案((可以從week10複製來用))

.....

加入glTranslatef函式使得手臂能移動
