Detailed Description

ZeroSkeleton processing package.

Author: Julien Tierny julie.nosp@m.n.ti.nosp@m.erny@.nosp@m.lip6.nosp@m..fr

Date: June 2015.

Member Function Documentation

◆ buildVertexEdges()

int ZeroSkeleton::buildVertexEdges	(	const SimplexId &	vertexNumber,
		const std::vector< std::array< SimplexId, 2 > > &	edgeList,
		FlatJaggedArray &	vertexEdges
	)		const

Compute the list of edges connected to each vertex of a triangulation.

Parameters

vertexNumber	Number of vertices in the triangulation.
edgeList	List of edges. Each entry is represented by the ordered std::pair of identifiers of the entry's edge's vertices.
vertexEdges	Output vertex links. The size of this std::vector will be equal to the number of vertices in the mesh. Each entry will be a std::vector listing the identifiers of the edges connected to the entry's vertex.

Returns: Returns 0 upon success, negative values otherwise.

Definition at line 9 of file ZeroSkeleton.cpp.

◆ buildVertexLinks() [1/2]

int ZeroSkeleton::buildVertexLinks	(	const FlatJaggedArray &	vertexStars,
		const std::vector< std::array< SimplexId, 3 > > &	cellEdges,
		const std::vector< std::array< SimplexId, 2 > > &	edgeList,
		FlatJaggedArray &	vertexLinks
	)		const

Compute the link of each vertex of a 2D triangulation (unspecified behavior if the input mesh is not a valid triangulation).

Parameters

vertexStars	List of vertex stars. The size of this std::vector should be equal to the number of vertices in the triangulation. Each entry is a std::vector listing the identifiers of triangles.
cellEdges	List of cell edges. The size of this std::vector should be equal to the number of triangles. Each entry is a std::array of identifiers of edges.
edgeList	List of edges. The size of this std::vector should be equal to the number of edges. Each entry is a std::array of vertex identifiers per edge.
vertexLinks	Output vertex links. The size of this std::vector will be equal to the number of vertices in the triangulation. Each entry will be a std::vector listing the edges in the link of the corresponding vertex.

Returns: Returns 0 upon success, negative values otherwise.

Definition at line 59 of file ZeroSkeleton.cpp.

◆ buildVertexLinks() [2/2]

int ZeroSkeleton::buildVertexLinks	(	const FlatJaggedArray &	vertexStars,
		const std::vector< std::array< SimplexId, 4 > > &	cellTriangles,
		const std::vector< std::array< SimplexId, 3 > > &	triangleList,
		FlatJaggedArray &	vertexLinks
	)		const

Compute the link of each vertex of a 3D triangulation (unspecified behavior if the input mesh is not a valid triangulation).

Parameters

vertexStars	List of vertex stars. The size of this std::vector should be equal to the number of vertices in the triangulation. Each entry is a std::vector listing the identifiers of tetrahedra.
cellTriangles	List of cell triangles. The size of this std::vector should be equal to the number of tetrahedra. Each entry is a std::vector of identifiers of triangles.
triangleList	List of triangles. For each triangle, a std::array identifying its three vertices.
vertexLinks	Output vertex links. The size of this std::vector will be equal to the number of vertices in the triangulation. Each entry will be a std::vector listing the triangles in the link of the corresponding vertex.

Returns: Returns 0 upon success, negative values otherwise.

Definition at line 116 of file ZeroSkeleton.cpp.

◆ buildVertexNeighbors()

int ZeroSkeleton::buildVertexNeighbors	(	const SimplexId &	vertexNumber,
		FlatJaggedArray &	vertexNeighbors,
		const std::vector< std::array< SimplexId, 2 > > &	edgeList
	)		const

Compute the list of neighbors of each vertex of a triangulation. Unspecified behavior if the input mesh is not a valid triangulation).

Parameters

vertexNumber	Number of vertices in the triangulation.
vertexNeighbors	Output neighbor list. The size of this std::vector will be equal to the number of vertices in the mesh. Each entry will be std::vector listing the vertex identifiers of the entry's vertex' neighbors.
edgeList	List of edges. If this std::vector is not empty but incorrect, the behavior is unspecified.

Returns: Returns 0 upon success, negative values otherwise.

Definition at line 173 of file ZeroSkeleton.cpp.

◆ buildVertexStars()

int ZeroSkeleton::buildVertexStars	(	const SimplexId &	vertexNumber,
		const CellArray &	cellArray,
		FlatJaggedArray &	vertexStars
	)		const

Compute the star of each vertex of a triangulation. Unspecified behavior if the input mesh is not a valid triangulation.

Parameters

vertexNumber	Number of vertices in the triangulation.
cellArray	Cell container allowing to retrieve the vertices of each cell.
vertexStars	Output vertex stars. The size of this std::vector will be equal to the number of vertices in the mesh. Each entry will be a std::vector listing the identifiers of the maximum-dimensional cells (3D: tetrahedra, 2D: triangles, etc.) connected to the entry's vertex.

Returns: Returns 0 upon success, negative values otherwise.
