1.
複製並將檔案移動做出transformation的模型
步驟:
1.複製貼上程式碼
2.把glm.c和glm.h丟進檔案中，並將glm.c改成glm.cpp

3.右鍵codeblock圖示增加glm.cpp檔案

4.把解壓縮的data丟進freeglut 一>bin


2.
自己打程式做出模型

程式碼:
#include <GL/glut.h>
#include "glm.h"
GLMmodel *model=NULL;
void display()
{
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    if(model==NULL)model = glmReadOBJ("data/Al.obj");
    glmUnitize(model);
    glmFacetNormals(model);
    glmVertexNormals(model,90);
    glmDraw(model, GLM_SMOOTH | GLM_MATERIAL);
    glutSwapBuffers();
}
int main(int argc,char**argv)
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);
    glutCreateWindow("自己做的");
    glutDisplayFunc(display);
    glutMainLoop();
}

3.
增加打光程式碼

打光程式碼:
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);

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);
