OuterPolyhedron

OuterPolyhedron[poly]

gives the outer polyhedron of the polyhedron poly.

Details

  • OuterPolyhedron is also known as polyhedron outer shell.
  • Typically used to decompose a polyhedron as a difference of simple polyhedra, even when the original construction of the polyhedron was using crossing curves etc.
  • OuterPolyhedron is defined by the canonicalization performed in CanonicalizePolyhedron.
  • OuterPolyhedron 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.
  • In general, the result will be a Polyhedron object representing a disjoint union of simple polygons.
