vtkCellCenters Class Reference
#include <vtkCellCenters.h>
Detailed Description
generate points at center of cellsvtkCellCenters 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.

- vtkGlyph3D vtkLabeledDataMapper

- vtkCellCenters (Examples)
- Tests:
- vtkCellCenters (Tests)

| 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 | |||
| ) | [protected, virtual] |
This is called by the superclass. This is the method you should override.
Reimplemented from vtkPolyDataAlgorithm.
| virtual int vtkCellCenters::FillInputPortInformation | ( | int | port, | |
| vtkInformation * | info | |||
| ) | [protected, virtual] |
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.
