## week06-0_sample_code

0.安裝 freeglut，將lib\libfreeglut.a複製成libglut32.a

1.File-New-Project,GLUT專案，week06-0_sample_code

2.研究一下 main.cpp 程式碼177行，找到全部的light(光)相關的程式(Ctrl+F)

  

```

    const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };

    const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat light_position[] = { 2.0f, 5.0f, 5.0f, 0.0f };

    const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

    const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };

    const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };

    const GLfloat high_shininess[] = { 100.0f };

```

```

glEnable(GL_DEPTH_TEST);

    glDepthFunc(GL_LESS);

    glEnable(GL_LIGHT0);

    glEnable(GL_NORMALIZE);

    glEnable(GL_COLOR_MATERIAL);

    glEnable(GL_LIGHTING);

    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);

    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);

    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);

    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

```

#week06-1_lighting

1.File-New-Project,GLUT專案，week06-1_lighting

2.先貼上11行GLUT的程式

3.再把剛剛的20行程式拿來用

4.會畫出一個很立體的茶壺

#week06-2_lighting_glNormal3f

1.File-New-Project,GLUT專案，week06-2_lighting_glNormal3f

2.貼上剛剛的week06-1_lighting程式

3.把茶壺變成正方形

4.加上mouse

#week06-3_glm_obj_model

1.File-New-Project,GLUT專案，week06-3_glm_obj_model

2.把11行程式GLUT先做出來

3.參考source.zip裡面的transformation.c，找裡面glm開頭的程式

3.1.#includ "glm.h"

3.2.GLMmodel*pmodel=NULL;

3.3.讀模型、畫模型，void drawmodel

4.將檔案準備好

4.1.glm.h放到week06-3_glm_obj_model目錄裡

4.2.glm.h放到week06-3_glm_obj_model目錄裡，改檔名成glm.cpp

4.3.專案，按右鍵，新增檔案，將glm.cpp加入專案

4.4.將data資料夾，複製到桌面\freeglut\bin 執行目錄裡(歷史餘毒)

4.5.把glutSolidTeapot(0.3);換成drawmodel();
