Dodecahedron

A dodecahedron has 12 similar regular pentagonal faces. The following examples show the same Dodecahedron using different projections:

     default_focus.set(2, 5, -10, 2, 5, 10, 10);
     Dodecahedron d(origin, 3);
     d.draw();

Please note that the Dodecahedron in [next figure] is drawn, and not filldrawn!

In [next figure] , d is filldrawn. In this case, the surface hiding algorithm has worked properly. See Surface Hiding.
