電腦圖學

1.主題:打光Part.1
2.主題:模型OBJ
3實作:GLM vs OBJ
4.回家作業

到http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/下載

將[data][win32]解壓縮
把[data]的資料夾放入window內 將glut32.dllu也放入window

開啟light&material
上圖換model
下圖換顏色

GLUT程式
1.網頁搜尋freeglut window->下載freeglut 3.0.0 MinGW Package
2.將壓縮檔拉至桌面
3.把資料夾開啟->lib資料夾開啟->將libfreeglut.a檔案負制病原地貼上->把複製檔重新命名為libglut32.a

4.進入code block

茶壺變成鐵黑
