week12-1_glm_gundam_handA_handB
先弄環境
freeglut
OpenCV2.1 記得Add PATH C:OpenCV2.1目錄
重開codeblocks
Setting-Compiler 要加入 OpenCV 相關的3個設定
-compiler 的 incldue 要加入 C:\OpenCV2.1\include
-linker 的lib 要加入 C:\OpenCV2.1\lib
-linker 設定 要加入 cv210 cxcore210 highgui210
把github程式載下來 git or download zip
要修改的程式: 把今天考試的 T-R-T 設定正確
技巧1: 把擋住的,註解掉
技巧2: 把用來對
3. glTranslatef();
2. glRotatef();
1. glTranslatef();
week-2_glm_gundam_upper_lower
要把上手臂,下手臂 切好 讀入
事先準備 把maya開起來 把handA.obj 讀入 切割出 upperA.obj 和 lowerA.obj
再把week12-1_glm_gundam_handA_handB 複製成 week12-2_glm_gundam_upperA_lowerA

} #執行結果
把week12-2_glm_gundam_upperA_lowerA
複製成week12-3_glm_gundam_keyboard_angleID_mouse_motion_angle
利用 mouse motion 來改變 angle
```cpp
float angle = 0, da = 1; //剛剛的舊的程式碼
void motion(int x, int y) { //加入 mouse motion 對應的函式
angle = y; //當我們的 mouse motion 時, y座標 對應角度
}
void display()
{
/// angle += da; //不要自己動 要用
