Week 10

主題: 
         (1) Maya匯出OBJ模型
         (2) glm讀模型
         (3) WAV音效,MP3音樂
         (4) 小遊戲 (回家作業)
        


課堂作業 : 
(1) jsyeh.org/3dcg10 下載
      source.zip→下載\windows\glm.c , glm.h , transformation.c
      windows.zip→下載\windows\transformation.exe
      data.zip→下載\windows\data\soccerball.obj , soccerball.mtl
      glut32.dll→下載\windows\glut32.dll

(2)用右鍵Notepad++開啟 soccerball.obj , soccerball.mtl

(3) myGLMsample.zip  解壓縮
       開啟  04160011_hw1.cbp
      Build&Run //F9
   注意: 裝freeglut在桌面
