vtkEdgeCenters Class Reference
#include <vtkEdgeCenters.h>
Detailed Description
generate points at center of edgesvtkEdgeCenters is a filter that takes as input any graph 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 edge 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.

| virtual const char* vtkEdgeCenters::GetClassName | ( | ) | [virtual] |
Reimplemented from vtkPolyDataAlgorithm.
| static int vtkEdgeCenters::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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataAlgorithm.
| virtual int vtkEdgeCenters::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 vtkTypeRevisionMacro found in vtkSetGet.h.
Reimplemented from vtkPolyDataAlgorithm.
| static vtkEdgeCenters* vtkEdgeCenters::SafeDownCast | ( | vtkObject * | o | ) | [static] |
Reimplemented from vtkPolyDataAlgorithm.
| void vtkEdgeCenters::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 vtkEdgeCenters* vtkEdgeCenters::New | ( | ) | [static] |
Construct object with vertex cell generation turned off.
Reimplemented from vtkPolyDataAlgorithm.
| virtual void vtkEdgeCenters::SetVertexCells | ( | int | ) | [virtual] |
Enable/disable the generation of vertex cells.
| virtual int vtkEdgeCenters::GetVertexCells | ( | ) | [virtual] |
Enable/disable the generation of vertex cells.
| virtual void vtkEdgeCenters::VertexCellsOn | ( | ) | [virtual] |
Enable/disable the generation of vertex cells.
| virtual void vtkEdgeCenters::VertexCellsOff | ( | ) | [virtual] |
Enable/disable the generation of vertex cells.
| virtual int vtkEdgeCenters::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 vtkEdgeCenters::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.
