 week11

1.下載設置檔案(glm.h,glm.cpp,transformation.c的內容)

2.加入data模型

3.車子模型

#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_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week11");

    glutDisplayFunc(display);

    glutMainLoop();

}

4.打光

轉向:

         glPushMatrix();        

             glRotatef(180,0,1,0);

         glPopMatrix();

打光:

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 };

 glEnable(GL_DEPTH_TEST); 

 glDepthFunc(GL_LESS);

 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);
