## week12-1_glm_gundam_handA_handB

1.建立專案
2.上週011-2

把環境設好: download opencv

小心:add PATH

小心:目錄不要改

小心:重開codeblocks

codeblocks: setting-compiler

Search directories的Compiler: C:\OpenCV2.1\include

Search directories的Linker: C:\OpenCV2.1\lib

Linker setting: cv210 cxcore210 highgui210

再把 Github 的程式下載(兩種下載法 Git指令 or Download ZIP)

再把week11-2改成week12-1

用右鍵Notepad++開 .cbp 檔，改Titlle

```cpp

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glDisable(GL_TEXTURE_2D);

    myBody();

    glutSolidSphere(0.1,30,30);///加一個圓球體代替旋轉中心

    glEnable(GL_TEXTURE_2D);

    glColor3f(1,1,1);

    glPushMatrix(); ///加這行, 讓它轉動

        glTranslatef(0.3,0.3,0);

        glRotatef(angle++,0,0,1);

        glTranslatef(0,-0.3,0);

        drawHandB(); //glutSolidTeapot( 0.3 );

    glPopMatrix();

    glPushMatrix(); ///加這行, 讓它轉動

        glTranslatef(-0.3,0.3,0);

        glRotatef(angle++,0,0,1);

        glTranslatef(0,-0.3,0);

        drawHandA(); //glutSolidTeapot( 0.3 );

    glPopMatrix();

    glutSwapBuffers();

}

```

## week12-2_glm_gundan_upper_lower

1.建立專案
2.拿week12-1程式全部拿來用

要把上手、下手臂切好、讀入

Maya開起來，把handA.obj 讀入、切割出upper.obj和lower.obj

加程式碼

```cpp

GLMmodel * upperA= NULL;

GLMmodel * lowerA= NULL;

```

再把void drawHandA() 複製修改成 void drawUpperA() 和 void drawUpperB()

加程式碼

```cpp

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glDisable(GL_TEXTURE_2D);

    ///myBody();

    glutSolidSphere(0.1,30,30);///加一個圓球體代替旋轉中心

    glEnable(GL_TEXTURE_2D);

    glColor3f(1,1,1);

    drawupperA();

    glPushMatrix();

        glTranslatef(-0.05,-0.1,0);

        glRotatef(angle++,0,0,1);///旋轉軸可自己改

        glTranslatef(0,-0.2,0);

        drawlowerA();

    glPopMatrix();

    glutSwapBuffers();

}

```

```cpp

float angle = 0, da = 1;///加這行, 讓它轉動

void display()

{

    angle+=da;

    if(angle>90) da=-1;

    if(angle<0) da=+1;

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glDisable(GL_TEXTURE_2D);

    ///myBody();

angle++改成angle

```

## week12-3_glm_gundan_keyboard_angleID_mouse_motion_angle

1.建立專案
2.拿week12-2程式全部拿來用
3.利用 mouse motion 來改成 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int main() 裡，加入glutMotionFunc(motion);

```cpp

void display()

{

    ///angle+=da;

    ///if(angle>90) da=-1;

    ///if(angle<0) da=+1;

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glDisable(GL_TEXTURE_2D);

    ///myBody();

    glutSolidSphere(0.1,30,30);///加一個圓球體代替旋轉中心

    glEnable(GL_TEXTURE_2D);

    glColor3f(1,1,1);

    glPushMatrix();

        ///glTranslatef();下禮拜繼續

        glRotatef(angle,0,0,1);

        glTranslatef(0,-0.07,0);

        drawupperA();

        glPushMatrix();

            glTranslatef(-0.02,-0.09,0);

            ///glRotatef(angle,1,0,0);

            glTranslatef(0,-0.21,0);

            drawlowerA();

    glPopMatrix();

    glutSwapBuffers();

}

```
