➽ 複習+期末作品

安裝OpenCV

要裝 PATH
CodeBlacks 要重開!!!
要設定:(Setting>Compiler)

Search directories>Compiler
C:\OpenCV2.1\include
Search directories>Linker
C:\OpenCV2.1\lib
Linker settings
cv210
cxcore210
highgui210

新增 GLUT專案

開啟Codeblocks>>開啟new project>>OpenGL
設定好 freeglut

下載freegult>>將lib裡的libfreeglut.a複製一份並改名libglut32.a
更改執行目錄(改成".")
要將 freeglut.dll 複製到自己的目錄裡

刪減範例程式

網址:http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/
下載 [source]
將[glm.c]更改為[glm.cpp]
將[glm.cpp]和[glm.h]拉到與專案同一層
在codeblocks裡加入[glm.cpp]
把 Gundam 的 OBJ 和 MTL 檔和圖檔拉入專案資料夾

MAYA 如何存各個部位

讀入一個模型檔
用 Separate 分解
選擇需要拆解的部位
Ctrl + G 群組起來
File>Export Selection 將選取部位存檔
