 ##week12-1_glm_gundam_handA_handB

0.開新的專案

1.安裝opencv

2.重開codeblocks，setting-compiler的3個設定

3.再把week11-2的程式下載

4.week11-2複製目錄，改目錄名為week12-1_glm_gundam_handA_handB

5.用nope++改目錄名

6.用codeblocks開啟week12-1

要修改今天的程式:把今天考試的TRT設定正確

技巧1:把擋住的，註解掉。把旋轉，

技巧2:把用來對照的座標原點，用glutSolidSphere(0.1,30,30);

##week12-2_glm_gundam_upper_lower

要把上手臂跟下手臂切好，讀入

maya開啟，把handA,obj讀入，切割出upper.obj和lower.obj

加程式

```cpp

GLMmodel*upperA讀入，切割出upper.obj和lowerA.obj

再把week12-1複製成week12-2

裡面的.cbp改檔名成week12-2_glm_gundam_upper_lower.cbp

再用Nope++把title和目錄,也更新成week12-2_glm_gundam_upper_lower

加程式

```cpp

GLMmodel*upperA=NULL;

GLMmodel*lowerA=NULL;

```

##week12-3_glm_gundam_keyboard_angleID_mouse_motion_angle

1.把week12-2複製成week12-3_glm_gundam_keyboard_angleID_mouse_motion_angle

2.利用mouse motion來改變angle

```cpp

float angle =0,da=1;

void motion(int x,int y){

    angle=y;

}

void display()

{

    ///angle+=da;

    ///if(angle>90)da=-1;

   /// if(angle<0)da=+1;

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

   ....

```

在in main()裡,加入glutMotionFunc(motion);
