digitalSurface2DualPolygonalSurface()

template<typename DigitalSurfaceContainer , typename CellEmbedder , typename VertexMap >

static void DGtal::MeshHelpers::digitalSurface2DualPolygonalSurface ( const DigitalSurface< DigitalSurfaceContainer > &  dsurf, const CellEmbedder &  cembedder, PolygonalSurface< typename CellEmbedder::Value > &  polysurf, VertexMap &  vertexmap  )

static

Builds a polygonal surface (class PolygonalSurface) from the dual graph of a 2-dimensional digital surface in K^3 (class DigitalSurface).

Template Parameters

DigitalSurfaceContainer	the container chosen for the digital surface.
CellEmbedder	the embedder chosen for the digital surface.

Parameters

[in]	dsurf	the input digital surface.
[in]	cembedder	the embedder for 2-cells of the digital surface, which are vertices in the output polygonal surface.
[out]	polysurf	the output polygonal surface mesh.
[out]	vertexmap	the output mapping between a Vertex of dsurf and an Index in polysurf.

digitalSurface2DualTriangulatedSurface()

template<typename DigitalSurfaceContainer , typename CellEmbedder , typename VertexMap >

static void DGtal::MeshHelpers::digitalSurface2DualTriangulatedSurface ( const DigitalSurface< DigitalSurfaceContainer > &  dsurf, const CellEmbedder &  cembedder, TriangulatedSurface< typename CellEmbedder::Value > &  trisurf, VertexMap &  vertexmap  )

static

Builds a triangulated surface (class TriangulatedSurface) from the dual graph of a 2-dimensional digital surface in K^3 (class DigitalSurface).

Note

that a triangulated surface contains only triangles, so faces of the input dual graph of the digital surface mesh are triangulated by adding a new vertex at the barycenter of the face vertices.

Template Parameters

DigitalSurfaceContainer	the container chosen for the digital surface.
CellEmbedder	the embedder chosen for the digital surface.

Parameters

[in]	dsurf	the input digital surface.
[in]	cembedder	the embedder for 2-cells of the digital surface, which are vertices in the output triangulated surface.
[out]	trisurf	the output triangulated surface mesh.
[out]	vertexmap	the output mapping between a Vertex of dsurf and an Index in trisurf.

mesh2PolygonalSurface()

template<typename Point >

static bool DGtal::MeshHelpers::mesh2PolygonalSurface ( const Mesh< Point > &  mesh, PolygonalSurface< Point > &  polysurf  )

static

Builds a polygon mesh (class PolygonalSurface) from a mesh (class Mesh). The output polygonal surface rebuilds a topology between faces.

Template Parameters

Point

the type for points.

Parameters

[in]	mesh	the input mesh.
[out]	polysurf	the output polygonal surface mesh.

Returns

'true' on success, 'false' if the input mesh was not a combinatorial surface.

mesh2TriangulatedSurface()

template<typename Point >

static bool DGtal::MeshHelpers::mesh2TriangulatedSurface ( const Mesh< Point > &  mesh, TriangulatedSurface< Point > &  trisurf  )

static

Builds a triangulated surface (class TriangulatedSurface) from a mesh (class Mesh). Note that a triangulated surface contains only triangles, so polygonal faces (0,1,2,3,4,...) of the input mesh are (naively) triangulated (triangles (0,1,2), (0,2,3), (0,3,4), etc). Furthermore, the output triangulated surface rebuilds a topology between faces.

Template Parameters

Point

the type for points.

Parameters

[in]	mesh	the input mesh.
[out]	trisurf	the output triangulated surface mesh.

Returns

'true' on success, 'false' if the input mesh was not a combinatorial surface.

polygonalSurface2Mesh()

template<typename Point >

static void DGtal::MeshHelpers::polygonalSurface2Mesh ( const PolygonalSurface< Point > &  polysurf, Mesh< Point > &  mesh  )

static

Builds a mesh (class Mesh) from a polygon mesh (class PolygonalSurface). Note that the mesh looses the topology of the polygonal surface, since it is essentially a soup of triangles.

Template Parameters

Point

the type for points.

Parameters

[in]	polysurf	the input polygonal surface (ie a polygon mesh).
[in,out]	mesh	the output mesh (which should be empty).

triangulatedSurface2Mesh()

template<typename Point >

static void DGtal::MeshHelpers::triangulatedSurface2Mesh ( const TriangulatedSurface< Point > &  trisurf, Mesh< Point > &  mesh  )

static

Builds a mesh (class Mesh) from a triangulated surface (class TriangulatedSurface). Note that the mesh looses the topology of the triangulated surface, since it is essentially a soup of triangles.

Template Parameters

Point

the type for points.

Parameters

[in]	trisurf	the input triangulated surface mesh.
[in,out]	mesh	the output mesh (which should be empty).
