主題：打光&模型obj檔

先到網址下載：
1.win32
2.source
3.data
4.glut32.dll

將win32、data解壓縮

 ！注意：source不用解壓縮直接放在window裡

<做出有光線的茶壺>

1.到https://www.transmissionzero.co.uk/software/freeglut-devel/ 下載

Download freeglut 3.0.0 for MinGW

2.都用好後到code開啟GLUT

3.打上程式

 #include <GL/glut.h>

 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 };

 void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week04");

    glutDisplayFunc(display);

    glClearColor(1,1,1,1);

    glEnable(GL_CULL_FACE);

    glCullFace(GL_BACK);

    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);

    glutMainLoop();

}

<用codeblock做出打光的模型>

1.由transformation.c 複製程式碼到codeblock\

2.把glm.c改成glm.cpp 並加到codeblock底下(要先放在資料夾內、再加入codeblock)

3.在freeglut的bin資料夾下加入data資料夾

4.完成~如果想更改模型(改這個檔名就好)
