Week08

記得要加glutSwapBuffers();不然會出錯

加入打光程式碼

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 };

int main()

{

glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

glutCreateWindow("week08");

glutDisplayFunc(display);

glutIdleFunc(idle);

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);

glutMainLoop();

}

加入眼睛程式碼

慢慢調整參數

void eye()

{

glPushMatrix();

glColor3f(1,1,1);

glTranslatef(0.075,0.35,0.225);

glutSolidSphere(0.1,20,20);

glColor3f(0,0,0);

glTranslatef(0.03,0.02,0.075);

glutSolidSphere(0.03,10,10);

glPopMatrix();

glPushMatrix();

glColor3f(1,1,1);

glTranslatef(-0.075,0.35,0.225);

glutSolidSphere(0.1,20,20);

glColor3f(0,0,0);

glTranslatef(-0.03,0.02,0.075);

glutSolidSphere(0.03,10,10);

glPopMatrix();

}
