Detailed Description

generate points at center of cells

vtkCellCenters is a filter that takes as input any dataset and generates on output points at the center of the cells in the dataset. These points can be used for placing glyphs (vtkGlyph3D) or labeling (vtkLabeledDataMapper). (The center is the parametric center of the cell, not necessarily the geometric or bounding box center.) The cell attributes will be associated with the points on output.

Warning:
You can choose to generate just points or points and vertex cells. Vertex cells are drawn during rendering; points are not. Use the ivar VertexCells to generate cells.

Member Function Documentation

virtual const char* vtkCellCenters::GetClassName ( )
virtual

Reimplemented from vtkPolyDataAlgorithm.

static int vtkCellCenters::IsTypeOf ( const char *  name)
static

Return 1 if this class type 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 vtkPolyDataAlgorithm.

virtual int vtkCellCenters::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 vtkPolyDataAlgorithm.

static vtkCellCenters* vtkCellCenters::SafeDownCast ( vtkObject o)
static

Reimplemented from vtkPolyDataAlgorithm.

void vtkCellCenters::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 vtkPolyDataAlgorithm.

static vtkCellCenters* vtkCellCenters::New ( )
static

Construct object with vertex cell generation turned off.

Reimplemented from vtkPolyDataAlgorithm.

virtual void vtkCellCenters::SetVertexCells ( int  )
virtual

Enable/disable the generation of vertex cells. The default is Off.

virtual int vtkCellCenters::GetVertexCells ( )
virtual

Enable/disable the generation of vertex cells. The default is Off.

virtual void vtkCellCenters::VertexCellsOn ( )
virtual

Enable/disable the generation of vertex cells. The default is Off.

virtual void vtkCellCenters::VertexCellsOff ( )
virtual

Enable/disable the generation of vertex cells. The default is Off.

virtual int vtkCellCenters::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
protectedvirtual

This is called by the superclass. This is the method you should override.

Reimplemented from vtkPolyDataAlgorithm.

virtual int vtkCellCenters::FillInputPortInformation ( int  port,
vtkInformation info 
)
protectedvirtual

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkPolyDataAlgorithm.
