◆ PrintSelf()

void vtkCell3D::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkCell.

Reimplemented in vtkConvexPointSet, vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPolyhedron, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

◆ GetEdgePoints()

virtual void vtkCell3D::GetEdgePoints	(	vtkIdType	edgeId,
		const vtkIdType *&	pts
	)

pure virtual

Get the pair of vertices that define an edge.

The method returns the number of vertices, along with an array of vertices. Note that the vertices are 0-offset; that is, they refer to the ids of the cell, not the point ids of the mesh that the cell belongs to. The edgeId must range between 0<=edgeId<this->GetNumberOfEdges().

Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

◆ GetFacePoints()

virtual vtkIdType vtkCell3D::GetFacePoints	(	vtkIdType	faceId,
		const vtkIdType *&	pts
	)

pure virtual

Get the list of vertices that define a face.

The list is terminated with a negative number. Note that the vertices are 0-offset; that is, they refer to the ids of the cell, not the point ids of the mesh that the cell belongs to. The faceId must range between 0<=faceId<this->GetNumberOfFaces().

Returns: The number of points in face faceId

Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

◆ GetEdgeToAdjacentFaces()

virtual void vtkCell3D::GetEdgeToAdjacentFaces	(	vtkIdType	edgeId,
		const vtkIdType *&	faceIds
	)

pure virtual

Get the ids of the two adjacent faces to edge of id edgeId.

The output face ids are sorted from id of lowest rank to highest. Note that the faces are 0-offset; that is, they refer to the ids of the cells, not the face ids of the mesh that the cell belongs to. The edgeId must range between 0<=edgeId<this->GetNumberOfEdges().

Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

◆ GetFaceToAdjacentFaces()

virtual vtkIdType vtkCell3D::GetFaceToAdjacentFaces	(	vtkIdType	faceId,
		const vtkIdType *&	faceIds
	)

pure virtual

Get the ids of the adjacent faces to face of id faceId.

The order of faces is consistent. They are always ordered in counter clockwise w.r.t. normal orientation. The first id faces[0] corresponds to the face sharing point of id pts[0] where pts is obtained from this->GetFacePoints(faceId, pts), being the "most counter clockwise" oriented w.r.t. face faceId. Note that the faces are 0-offset; that is, they refer to the ids of the cell, not the face ids of the mesh that the cell belongs to. The faceId must be between 0<=faceId<this->GetNumberOfFaces();

Warning: If the vtkCell3D is "inside out", i.e. normals point inside the cell, the order is inverted.

Returns: The number of adjacent faces to faceId.

Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkWedge, and vtkVoxel.

◆ GetPointToIncidentEdges()

virtual vtkIdType vtkCell3D::GetPointToIncidentEdges	(	vtkIdType	pointId,
		const vtkIdType *&	edgeIds
	)

pure virtual

Get the ids of the incident edges to point of id pointId.

Edges are sorted in counter clockwise order w.r.t. bisectrix pointing outside the cell at point of id pointId. The first edge corresponds to the edge containing point of id pts[0], where pts is obtained from this->GetPointToOnRingVertices(pointId, pts). Note that the edges are 0-offset; that is, they refer to the ids of the cell, not the edge ids of the mesh that the cell belongs to. The edgeId must be between 0<=edgeId<this->GetNumberOfEdges();

Warning: If the vtkCell3D is "inside out", i.e. normals point inside the cell, the order is inverted.

Returns: The valence of point pointId.

Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkWedge, and vtkVoxel.

◆ GetPointToIncidentFaces()

virtual vtkIdType vtkCell3D::GetPointToIncidentFaces	(	vtkIdType	pointId,
		const vtkIdType *&	faceIds
	)

pure virtual

Get the ids of the incident faces point of id pointId.

Faces are sorted in counter clockwise order w.r.t. bisectrix pointing outside the cell at point of id pointId. The first face corresponds to the face containing edge of id edges[0], where edges is obtained from this->GetPointToIncidentEdges(pointId, edges), such that face faces[0] is the "most counterclockwise" face incident to point pointId containing edges[0]. Note that the faces are 0-offset; that is, they refer to the ids of the cell, not the face ids of the mesh that the cell belongs to. The pointId must be between 0<=pointId<this->GetNumberOfPoints().

Warning: If the vtkCell3D is "inside out", i.e. normals point inside the cell, the order is inverted.

Returns: The valence of point pointId.

Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPolyhedron, vtkPyramid, vtkTetra, vtkWedge, and vtkVoxel.

◆ GetPointToOneRingPoints()

virtual vtkIdType vtkCell3D::GetPointToOneRingPoints	(	vtkIdType	pointId,
		const vtkIdType *&	pts
	)

pure virtual

Get the ids of a one-ring surrounding point of id pointId.

Points are sorted in counter clockwise order w.r.t. bisectrix pointing outside the cell at point of id pointId. The first point corresponds to the point contained in edges[0], where edges is obtained from this->GetPointToIncidentEdges(pointId, edges). Note that the points are 0-offset; that is, they refer to the ids of the cell, not the point ids of the mesh that the cell belongs to. The pointId must be between 0<pointId<this->GetNumberOfPoints().

Returns: The valence of point pointId.

Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

◆ IsInsideOut()

virtual bool vtkCell3D::IsInsideOut ( )

virtual

Returns true if the normals of the vtkCell3D point inside the cell.

Warning: This flag is not precomputed. It is advised for the return result of this method to be stored in a local boolean by the user if needed multiple times.

Reimplemented in vtkHexagonalPrism, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

◆ GetCentroid()

virtual bool vtkCell3D::GetCentroid ( double centroid[3] ) const

pure virtual

Computes the centroid of the cell.

Implemented in vtkHexagonalPrism, vtkHexahedron, vtkPentagonalPrism, vtkPyramid, vtkTetra, vtkVoxel, and vtkWedge.

◆ Contour()

void vtkCell3D::Contour	(	double	value,

		vtkIncrementalPointLocator *	locator,
		vtkCellArray *	verts,
		vtkCellArray *	lines,
		vtkCellArray *	polys,
		vtkPointData *	inPd,
		vtkPointData *	outPd,
		vtkCellData *	inCd,
		vtkIdType	cellId,
		vtkCellData *	outCd
	)

overridevirtual

Generate contouring primitives.

The scalar list cellScalars are scalar values at each cell point. The point locator is essentially a points list that merges points as they are inserted (i.e., prevents duplicates). Contouring primitives can be vertices, lines, or polygons. It is possible to interpolate point data along the edge by providing input and output point data - if outPd is nullptr, then no interpolation is performed. Also, if the output cell data is non-nullptr, the cell data from the contoured cell is passed to the generated contouring primitives. (Note: the CopyAllocate() method must be invoked on both the output cell and point data. The cellId refers to the cell from which the cell data is copied.)

Implements vtkCell.

Reimplemented in vtkConvexPointSet, vtkHexahedron, vtkPyramid, vtkTetra, vtkVoxel, vtkWedge, and vtkPolyhedron.

◆ Clip()

void vtkCell3D::Clip	(	double	value,
		vtkDataArray *	cellScalars,
		vtkIncrementalPointLocator *	locator,
		vtkCellArray *	connectivity,
		vtkPointData *	inPd,
		vtkPointData *	outPd,
		vtkCellData *	inCd,
		vtkIdType	cellId,
		vtkCellData *	outCd,
		int	insideOut
	)

overridevirtual

Cut (or clip) the cell based on the input cellScalars and the specified value.

The output of the clip operation will be one or more cells of the same topological dimension as the original cell. The flag insideOut controls what part of the cell is considered inside - normally cell points whose scalar value is greater than "value" are considered inside. If insideOut is on, this is reversed. Also, if the output cell data is non-nullptr, the cell data from the clipped cell is passed to the generated contouring primitives. (Note: the CopyAllocate() method must be invoked on both the output cell and point data. The cellId refers to the cell from which the cell data is copied.) (Satisfies vtkCell API.)

Implements vtkCell.

Reimplemented in vtkConvexPointSet, vtkTetra, and vtkPolyhedron.

◆ GetCellDimension()

int vtkCell3D::GetCellDimension ( )

inlineoverridevirtual

The topological dimension of the cell.

(Satisfies vtkCell API.)

Implements vtkCell.

Reimplemented in vtkHexagonalPrism, vtkPentagonalPrism, vtkPyramid, vtkVoxel, and vtkWedge.

Definition at line 169 of file vtkCell3D.h.

◆ Inflate()

int vtkCell3D::Inflate ( double dist )

overridevirtual

Inflates the cell.

Each face is displaced following its normal by a distance of value dist. If dist is negative, then the cell shrinks. The resulting cell edges / faces are colinear / coplanar to their previous self.

Degenerate parts of the 3D cell are unchanged. This happens a points to which incident faces are homogeneous to a plane, to a line, or to a point.

Returns: 1 if inflation was successful, 0 if no inflation was performed

Reimplemented from vtkCell.

Reimplemented in vtkVoxel.
