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 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.

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.)

Reimplemented in vtkPolyhedron, vtkConvexPointSet, and vtkTetra.

virtual int vtkCell3D::GetCellDimension ( )
inlinevirtual

The topological dimension of the cell. (Satisfies vtkCell API.)

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

virtual void vtkCell3D::SetMergeTolerance ( double  )
virtual

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 ( )
virtual

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.
