It depends on what kind of polyhedra you want. How many faces? Regular,
irregular? If irregular, how many different faces? How many sides per face?

They are all in the standard include file 'shapes2.inc'. See that file fore
details. So:
#include "shapes2.inc"
object{Tetrahedron pigment{White} ...}
object{Octahedron ...}
object{Dodecahedron ...}
object{Icosahedron ...}
You can even do
object{Hexagon ...}
tough I don't know if that makes scenes. Isn't it always better just to use a box
for that?

You can intersect planes for a "solid" one, or for speed's sake you can use
triangle meshes. I have an include file for mesh polyhedra at my site if you
want.

Rendering the slow version took 42 minutes and 45 s on my Pentium 133

Rendering the new, faster one only 18 minutes and 26 s.
