static PointelRange DGtal::Shortcuts< TKSpace >::getPointelRange	(	Cell2Index &	c2i,
		CountedPtr< ::DGtal::DigitalSurface< TDigitalSurfaceContainer > >	surface
	)

inlinestatic

Given any digital surface, returns the vector of its pointels.

Note: The order of pointels is given by the default traversal of the surfels of the surface, where the 4 pointels of each surfel are visited in order.

Since: 1.1 The pointel ordering is now the same as the one given by makePrimalPolygonalSurface (for 3D only of course).

Note: If you wish to consider the primal digital surface, and visits pointels as vertices of this graph in breadth-first/depth-first order, the best is to build first a PolygonalSurface and then use specialized visitors.

Template Parameters

TDigitalSurfaceContainer either kind of DigitalSurfaceContainer

Parameters

[out]	c2i	the map Cell -> Vertex index in the pointel range.
[in]	surface	a smart pointer on a (light or not) digital surface (e.g. DigitalSurface or LightDigitalSurface).

Returns: a range of pointels as a vector.

template<typename TKSpace >

static CountedPtr< TriangulatedSurface > DGtal::Shortcuts< TKSpace >::makeTriangulatedSurface ( CountedPtr< Mesh > aMesh )

inlinestatic

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.

Parameters

[in] aMesh any mesh (which should be a valid combinatorial surface).

Returns: a smart pointer on the built triangulated surface or 0 if the mesh was invalid.

		const Parameters &	params = `parametersMesh()`
	)

inlinestatic

Builds a triangulated surface from a polygonal surface.

Note: Be very careful with "Naive" subdivision, since it may create non-manifold edges on general polygonal surfaces. Indeed, take the closed surface made of faces (0, 1, 2, 3) and (3, 2, 1, 0). Depending on how faces are triangulated, it is still a valid combinatorial triangulated 2-manifold (e.g. (0,1,2,3) gives (0,1,2) and (2,0,3) and (3,2,1,0) gives (3,2,1) and (1,3,0)) or a non-valid one (e.g. (0,1,2,3) gives (0,1,2) and (2,0,3) and (3,2,1,0) gives (3,2,0) and (0,2,1): then edge {2,0} is shared by four faces).

Parameters

[in]	polySurf	any polygonal surface.
[in]	params	the parameters: faceSubdivision ["Centroid"]: "No"\|"Naive"\|"Centroid" specifies how faces are subdivided, "No" is considered as "Naive" since faces must be triangulated.

Returns: a smart pointer on the built triangulated surface.
