20行程式：

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 };

   (2行) glEnable(GL_DEPTH_TEST);

    glDepthFunc(GL_LESS);

    (12行)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. 貼上11程式
2. 再貼上剛剛的12行
3. 會畫出立體的茶壺

11行程式：

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT); //清除後才可畫新圖案

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week06 lighting");

    glutDisplayFunc(display);

    glutMainLoop();

}

##week06-2_lighting_glNormal3f

1.貼上剛剛的week06-1_lighting的程式

2.打茶壺變成一個正方形

3.加上mouse 轉動正方形

##week06-3_glm_obj_model

1. 貼上11行程式

2 .參考sources.zip 裡面的 transformation.c

2-1 #include "glm.h"

2.2 GLMmodel * pmodel = NULL;

2.3 讀模型，畫模型

3. glm.h放到 week06-3_glm_obj_model目錄裡

3.1 glm.c放到 week06-3_glm_obj_model目錄裡，改檔名城glm.cpp

3.2專案，按右鍵，新增檔案，將glm.cpp加入專案

3.3將data資料夾，複製到\freeglut\bin目錄裡
