記得先將glm.c和glm.h兩個檔案放入我們的資料夾中

之後要把glm.c的副檔名改成glm.cpp再加入執行檔裡

1.讀入圖檔(記得把圖檔放入freeglut裡的bin資料夾裡)

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

    glmDraw(pmodel,GLM_SMOOTH |GLM_MATERIAL);

    glFlush();

}

int main(int argc,char**argv)

{

    pmodel = glmReadOBJ("porsche.obj");

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

    glmVertexNormals(pmodel,90.0);

    glutInit(&argc,argv);

    glutCreateWindow("GLUT");

    glutDisplayFunc(display);

    glutMainLoop();

}

2.插入打光的功能

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

    GLfloat pos[] = { 0.0, 0.0, -1.0, 0.0 };

    glLightfv(GL_LIGHT0, GL_POSITION, pos);

    glEnable(GL_LIGHTING);

    glEnable(GL_LIGHT0);

    glEnable(GL_DEPTH_TEST);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glmDraw(pmodel,GLM_SMOOTH |GLM_MATERIAL);

    glFlush();

}

int main(int argc,char**argv)

{

    pmodel = glmReadOBJ("porsche.obj");

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

    glmVertexNormals(pmodel,90.0);

    glutInit(&argc,argv);

    glutCreateWindow("GLUT");

    glutDisplayFunc(display);

    glutMainLoop();

}
