- // PolyWood.pov - Wooden polyhedron hollowed by a sphere
- // on a grassy hilly lawn. Shows how easy it is to
- // create interesting shapes with CSG operations
- // and simple primitive shapes.

- // The Wooden Polyhedron
- // The idea here is to take a few cubes rotated at 45 degrees
- // along different axes from each other and intersect them,
- // thus cutting some corners. Then we carve out the center
- // with a slightly oversized sphere, which protrudes slightly
- // through the sides, cutting portholes in the facets of the
- // polyhedron. Then we get out the wooden paint..
