1.利用glm讀入OBJ模型

(1)在3dcg10的網站: http://www.cmlab.csie.ntu.edu.tw/~jsyeh/3dcg10/    下載source,data,win32,glut32.dll並解壓縮

(2)在codeblocks打開glut專案並把裡面的範例程式刪掉

(3)把source裡面的transformation.c用notepad++打開並複製裡面的程式

然後貼到codeblocks裡

(4)將source裡的glm.c和glm.h拉進專案的資料夾

     然後把glm.c的檔名改成cpp

(5)在專案中加入glm.cpp

(6)把data資料夾拉進freeglut/bin

2.親手打造glmDraw()



#include <GL/glut.h>
#include "glm.h"

GLMmodel* model = NULL;

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);
   if(model==NULL) {
        model = glmReadOBJ("DATA/Al.obj");
        glmUnitize(model);
        glmFacetNormals(model);
        glmVertexNormals(model, 90);
    }
    glPushMatrix();
    glRotatef(180,0,1,0);
        glmDraw(model, GLM_SMOOTH|GLM_MATERIAL);
    glPopMatrix();
    glutSwapBuffers();
}
main(int argc, char** argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);
    glutCreateWindow("親手打造的");
    glutDisplayFunc(display);
    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);

    glutMainLoop();
