## Definition

template<class TriangleMesh, class VPM1 = typename boost::property_map<TriangleMesh, vertex_point_t>::type, class VPM2 = typename boost::property_map<TriangleMesh, vertex_point_t>::type>
struct CGAL::Polygon_mesh_processing::Corefinement::Non_manifold_output_visitor< TriangleMesh, VPM1, VPM2 >

Is model of
  `PMPCorefinementVisitor`

A model of `PMPCorefinementVisitor` that enables extracting non-manifold outputs from a corefinement-based Boolean Operations (Corefinement and Boolean Operations).

Template Parameters

  TriangleMesh | a model of `HalfedgeListGraph`, `FaceListGraph`, and `MutableFaceGraph`
  VPM1 | a class model of `ReadablePropertyMap` with `boost::graph_traits<TriangleMesh>::vertex_descriptor` as key type and an unspecified type `Point_3` as value type
  VPM2 | a class model of `ReadablePropertyMap` with `boost::graph_traits<TriangleMesh>::vertex_descriptor` as key type and the same value type as `VPM1`

## ◆ Non_manifold_output_visitor()

template<class TriangleMesh , class VPM1 = typename boost::property_map<TriangleMesh, vertex_point_t>::type, class VPM2 = typename boost::property_map<TriangleMesh, vertex_point_t>::type>

CGAL::Polygon_mesh_processing::Corefinement::Non_manifold_output_visitor< TriangleMesh, VPM1, VPM2 >::Non_manifold_output_visitor | ( | TriangleMesh & | tm1,
|  | TriangleMesh & | tm2,
|  | VPM1 | vpm1 = `get(CGAL::vertex_point, tm1)`,
|  | VPM1 | vpm2 = `get(CGAL::vertex_point, tm2)`
| ) |  |

constructor where meshes are exactly the same as the one passed a function in Corefinement and Boolean Operations.

The visitor cannot be reused for several calls to the aforementioned function.

Parameters

  tm1 | first triangle mesh in the same order as in the function in Corefinement and Boolean Operations
  tm2 | second triangle mesh in the same order as in the function in Corefinement and Boolean Operations
  vpm1 | vertex point map for `tm1`
  vpm2 | vertex point map for `tm2`
