gives the inner polyhedron of the polyhedron poly.


  • 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.
