Detailed Description

abstract class to specify 3D cell interface

vtkCell3D is an abstract class that extends the interfaces for 3D data cells, and implements methods needed to satisfy the vtkCell API. The 3D cells include hexehedra, tetrahedra, wedge, pyramid, and voxel.

virtual int vtkCell3D::IsA ( const char * name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkCell.

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

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

virtual

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

virtual void vtkCell3D::GetEdgePoints	(	int	edgeId,
		int *&	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 vtkPentagonalPrism, vtkPyramid, vtkWedge, vtkHexagonalPrism, vtkHexahedron, vtkTetra, and vtkVoxel.

virtual void vtkCell3D::GetFacePoints	(	int	faceId,
		int *&	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().

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

virtual void vtkCell3D::Contour	(	double	value,
		vtkDataArray *	cellScalars,
		vtkIncrementalPointLocator *	locator,
		vtkCellArray *	verts,

		vtkPointData *	inPd,
		vtkPointData *	outPd,
		vtkCellData *	inCd,
		vtkIdType	cellId,
		vtkCellData *	outCd
	)

virtual

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 NULL, then no interpolation is performed. Also, if the output cell data is non-NULL, 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 vtkPolyhedron, vtkConvexPointSet, vtkPyramid, vtkWedge, vtkHexahedron, vtkTetra, and vtkVoxel.

		vtkCellData *	inCd,
		vtkIdType	cellId,
		vtkCellData *	outCd,
		int	insideOut
	)

virtual

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-NULL, 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.)

virtual void vtkCell3D::SetMergeTolerance ( double )

Set the tolerance for merging clip intersection points that are near the vertices of cells. This tolerance is used to prevent the generation of degenerate tetrahedra during clipping.

virtual double vtkCell3D::GetMergeTolerance ( )
