Detailed Description

generate points at center of cells.

Date:

2000/12/10 20:08:31

Revision:

1.12

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]

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToPolyDataFilter.

int vtkCellCenters::IsTypeOf (  const char *    type )  [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 vtkDataSetToPolyDataFilter.

virtual int vtkCellCenters::IsA (  const char *    type )  [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 vtkDataSetToPolyDataFilter.

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

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkDataSetToPolyDataFilter.

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 vtkSource.

vtkCellCenters* vtkCellCenters::New (    )  [static]

Construct object with vertex cell generation turned off. Reimplemented from vtkPolyDataSource.

virtual void vtkCellCenters::SetVertexCells (  int    )  [virtual]

Enable/disable the generation of vertex cells.

virtual int vtkCellCenters::GetVertexCells (    )  [virtual]

virtual void vtkCellCenters::VertexCellsOn (    )  [virtual]

virtual void vtkCellCenters::VertexCellsOff (    )  [virtual]

void vtkCellCenters::operator= (  const vtkCellCenters &    )  [inline, protected]

Definition at line 87 of file vtkCellCenters.h.

void vtkCellCenters::Execute (    )  [protected, virtual]

Reimplemented from vtkSource.
