(1)3D模型

#include "glm.h" //我們要用glm.h 和 glm.c (要先copy到同目錄)

GLMmodel* pmodel = NULL;  //宣告 有個pointer指到model

void display()

{

    glmDraw(pmodel,GLM_SMOOTH | GLM_MATERIAL);

    glFlush();

}

int main(int argc,char**argv)

{

    pmodel = glmReadOBJ("porsche.obj"); //如果沒檔案/找不到 就會當機

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

    glmVertexNormals(pmodel, 90.0);

    glutInit(&argc,argv);

    glutCreateWindow("02160615");

    glutDisplayFunc(display);

    glutMainLoop();

}

(2)打光

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

    GLfloat pos[] = { 0.0, 0.0, -1.0, 0.0 }; //光的位置

    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("02160615");

glutDisplayFunc(display);

glutMainLoop();

}
