InnerPolyhedron
InnerPolyhedron[poly]
gives the inner polyhedron of the polyhedron poly.
Details

- InnerPolyhedron is also known as polyhedron inner void.
- Typically used to decompose a polyhedron as a difference of simple polyhedrons, even when the original construction of the polyhedron was using crossing polygon faces etc.
- InnerPolyhedron is defined by the canonicalization performed in CanonicalizePolyhedron.
- InnerPolyhedron gives a polyhedron of the form Polyhedron[{p1,p2,…}, {{f1,f2,…},…}], where pk are explicit coordinates, and fk are integer lists referring to polygon faces.
- If poly is a polyhedron without a void, then the result is an EmptyRegion object.
