要將3D模組匯入程式中

先將glm.c和glm.h放同目錄，把.c改成cpp，接著都放進執行處

然後把cpp打開，找出glm的程式碼，複製貼上到程式中

#include "glm.h"

GLMmodel* pmodel=NULL;

int main (){

pmodel = glmReadOBJ("data/porsche.obj");

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

把windows裡的porsche丟入freeglut資料夾

打上些3D程式碼

最後加上光源(光源座標要注意)

最終的程式碼

#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){

glutInit(&argc,argv);

glutCreateWindow("02160820");

glutDisplayFunc(display);

pmodel = glmReadOBJ("porsche.obj");

glmUnitize(pmodel);

glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

glutMainLoop();

}
