bool CGAL::output_surface_facets_to_polyhedron | ( | const SurfaceMeshComplex_2InTriangulation_3 & | c2t3,
|  | Polyhedron & | output_polyhedron
| ) |  |

Deprecated:
  Gets reconstructed surface out of a SurfaceMeshComplex_2InTriangulation_3 object.

This variant exports the surface as a polyhedron. It requires the surface to be manifold. For this purpose, you may call make_surface_mesh() with Manifold_tag or Manifold_with_boundary_tag parameter.

Template Parameters

  SurfaceMeshComplex_2InTriangulation_3 | model of the SurfaceMeshComplex_2InTriangulation_3 concept.
  Polyhedron | an instance of CGAL::Polyhedron_3<Traits>.

Parameters

  c2t3 | the input.
  output_polyhedron | the output.

Returns
  true if the surface is manifold and orientable.
