week11東西有點多歐

 要把目斗的source.zip解壓縮

然後會看到

glm.h glm.c和transformation.c

把他們放到你新開的glut專案的lib裡面

記得glm.c要改成glm.cpp!!

然後再把transformation 的程式碼拿來貼在maincpp的程式碼裡面 啊原本maincpp 的程式碼要刪掉歐！

最後再把data解壓縮過後的資料夾放在bin裡面（不是你開的新專案是原本的freeglut）

那個怪怪的東西就會出現啦

之後再把main.cpp裡面的程式碼改成下列

#include "glm.h"

GLMmodel* pmodel = NULL;

void drawmodel(void)

{

    if (!pmodel) {

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

    if (!pmodel) exit(0);

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

    glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    drawmodel();

    glutSwapBuffers();

}

int main(int argc, char **argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160732 week11");

    glutDisplayFunc(display);

    glutMainLoop();

}

就會變成這樣

打光時間!!!

先把車換成胖子

然後貼上以下程式碼

#include "glm.h"

GLMmodel* pmodel = NULL;

void drawmodel(void)

{

    if (!pmodel) {

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

    if (!pmodel) exit(0);

    glmUnitize(pmodel);

    glmFacetNormals(pmodel);

    glmVertexNormals(pmodel, 90.0);

    }

    glmDraw(pmodel, GLM_SMOOTH | GLM_MATERIAL);

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(180,0,1,0);

        drawmodel();

    glutSwapBuffers();

}

const GLfloat light_ambient[]  = { 0.0f, 0.0f, 0.0f, 1.0f };

const GLfloat light_diffuse[]  = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat light_specular[] = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat light_position[] = { 2.0f, 5.0f, -5.0f, 0.0f };

const GLfloat mat_ambient[]    = { 0.7f, 0.7f, 0.7f, 1.0f };

const GLfloat mat_diffuse[]    = { 0.8f, 0.8f, 0.8f, 1.0f };

const GLfloat mat_specular[]   = { 1.0f, 1.0f, 1.0f, 1.0f };

const GLfloat high_shininess[] = { 100.0f };

int main(int argc, char **argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160732 week11");

    glEnable(GL_DEPTH_TEST);

    glEnable(GL_LIGHT0);

    glEnable(GL_NORMALIZE);

    glEnable(GL_COLOR_MATERIAL);

    glEnable(GL_LIGHTING);

    glLightfv(GL_LIGHT0, GL_AMBIENT,  light_ambient);

    glLightfv(GL_LIGHT0, GL_DIFFUSE,  light_diffuse);

    glLightfv(GL_LIGHT0, GL_SPECULAR, light_specular);

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);

    glMaterialfv(GL_FRONT, GL_AMBIENT,   mat_ambient);

    glMaterialfv(GL_FRONT, GL_DIFFUSE,   mat_diffuse);

    glMaterialfv(GL_FRONT, GL_SPECULAR,  mat_specular);

    glMaterialfv(GL_FRONT, GL_SHININESS, high_shininess);

    glutDisplayFunc(display);

    glutMainLoop();

}

打完就會變成下面這個胖子
