1.作業回顧
2.作業需求
3.3D model 模型
4.Maya 轉 OBJ
5.介紹助教影片資源



(1)

先將source壓縮檔壓縮

將GLM檔案(glm.h、glm.c)放入專案資料夾

glm.c副檔名改成.cpp

(2)run 結果

#include "glm.h"

GLMmodel* pmodel = NULL;

int main (int argc, char **argv)

{

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

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

    glmVertexNormals(pmodel, 90.0);

}

(3) 把3D  模型秀出

#include "glm.h"

GLMmodel* pmodel = NULL;

void display()

{

    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_02160270");

    glutDisplayFunc(display);

    pmodel = glmReadOBJ("porsche.obj");

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

    glmVertexNormals(pmodel, 90.0);

    glutMainLoop();

}

(4)加上打光效果

 #include "glm.h"
GLMmodel* pmodel = NULL;

void display()
{
//打光效果
    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);
    ///glClear（）函数的作用是用当前缓冲区清除值
    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);
    glFlush();
}

int main (int argc, char **argv)
{
    glutInit(&argc, argv);
    glutCreateWindow("GLUT_02160270");
    glutDisplayFunc(display);

    pmodel = glmReadOBJ("porsche.obj");
    glmUnitize(pmodel);
    glmFacetNormals(pmodel);
    glmVertexNormals(pmodel, 90.0);
    glutMainLoop();
}
