1.作業回顧

2.作業需求(小遊戲)

3.3D Model模型glm.c

4.Maya轉OBJ檔

5.介紹助教影片資源


執行Transformation檔案

#include "glm.h"

GLMmodel* pmodel = NULL;

int main()

{

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

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

}

讓資料夾出現副檔名

加入glm.cpp

跑出小黑視窗

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

    glmDraw(pmodel,GLM_SMOOTH|GLM_MATERIAL);

    glFlush();

}

int main(int argc,char**argv)

{

    glutInit(&argc,argv);

    glutCreateWindow("GLUT");

    glutDisplayFunc(display);

    pmodel = glmReadOBJ("porsche.obj");

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    glutMainLoop();

}

做出沒有顏色的車子

#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("GLUT");

    glutDisplayFunc(display);

    pmodel = glmReadOBJ("porsche.obj");

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

glmVertexNormals(pmodel, 90.0);

    glutMainLoop();

}
