DualPolyhedron

DualPolyhedron[poly]

gives the dual polyhedron of the polyhedron poly.

Details and Options

  • DualPolyhedron is also known as reciprocal or topological dual polyhedron.
  • DualPolyhedron generates a Polyhedron with vertex points corresponding to faces of poly and edges corresponding to edges between faces of poly.
  • A typical choice for the vertex points of the dual polyhedron is to use the centroid from each face of poly.
  • DualPolyhedron takes the same options as Polyhedron.
