Это ужас. Геометрия у меня ни какая) Кто нибудь может объяснить кака задается вектор освещения? Вот :

Код


glBegin(GL_TRIANGLES);
 //glNormal3f(0.0, 0.0, 1.0);
  glcolor3f(0.0,0.0,0.0);
 glVertex3f(0.3,0.0,0.3);
  glColor3f(0.0,0.0,0.0);
 glVertex3f(-0.3,0.0,0.3);
  glcolor3f(0.0,0.0,1.0);
 glVertex3f(0.0,0.5,0.0);
 glEnd;

 glBegin(GL_TRIANGLES);
//glNormal3f(0.0, 0.0, 1.0);
  glcolor3f(0.0,0.0,0.0);
 glVertex3f(0.3,0.0,-0.3);
  glColor3f(0.0,0.0,0.0);
 glVertex3f(-0.3,0.0,-0.3);
  glcolor3f(0.0,0.0,1.0);
 glVertex3f(0.0,0.5,0.0);
 glEnd;

 glBegin(GL_TRIANGLES);
 //glNormal3f(1.0, 0.0, 0.0);
  glcolor3f(0.0,0.0,0.0);
 glVertex3f(-0.3,0.0,-0.3);
  glColor3f(0.0,0.0,0.0);
 glVertex3f(-0.3,0.0,0.3);
  glcolor3f(0.0,0.0,1.0);
 glVertex3f(0.0,0.5,0.0);
 glEnd;

 glBegin(GL_TRIANGLES);
 //glNormal3f(1.0, 0.0, 0.0);
  glcolor3f(0.0,0.0,0.0);
 glVertex3f(0.3,0.0,-0.3);
  glColor3f(0.0,0.0,0.0);
 glVertex3f(0.3,0.0,0.3);
  glcolor3f(0.0,0.0,1.0);
 glVertex3f(0.0,0.5,0.0);
 glEnd;

 glBegin (GL_QUADS );
  // glNormal3f(0.0, -1.0, 0.0);
  glColor3f(0.0,0.0,1.0);
  glVertex3f(0.3,0.0,0.3);
  glColor3f(0.0,0.0,0.0);
  glVertex3f(-0.3,0.0,0.3);
  glColor3f(0.0,0.0,1.0);
  glVertex3f(-0.3,0.0,-0.3);
  glColor3f(0.0,0.0,0.0);
  glVertex3f(0.3, 0.0, -0.3);
 glEnd;


 glBegin(GL_LINES);
   glColor3f(1.0,0.0,0.0);
  glVertex3f(-1.0,0.0,0.0);
  glVertex3f(1.0,0.0,0.0);
   glColor3f(0.0,1.0,0.0);
  glVertex3f(0.0,-1.0,0.0);
  glVertex3f(0.0,1.0,0.0);
     glColor3f(0.0,0.0,1.0);
  glVertex3f(0.0,0.0,-1.0);
  glVertex3f(0.0,0.0,1.0);

 glEnd;

Какие цифры в glNormal3f нужно написать чтобы нормально освещалася пирамида т.е. спереди?? Как в примерах (многочисленных) с кубом..
брр
и ещё.. а как сделать цветное свечение? )
