Detailed Description

generate scalars or field data from point and cell ids

vtkIdFilter is a filter to that generates scalars or field data using cell and point ids. That is, the point attribute data scalars or field data are generated from the point ids, and the cell attribute data scalars or field data are generated from the the cell ids.

Typically this filter is used with vtkLabeledDataMapper (and possibly vtkSelectVisiblePoints) to create labels for points and cells, or labels for the point or cell data scalar values.

Member Function Documentation

virtual const char* vtkIdFilter::GetClassName (  )  [virtual]

Reimplemented from vtkDataSetAlgorithm.

static int vtkIdFilter::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 vtkDataSetAlgorithm.

virtual int vtkIdFilter::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 vtkDataSetAlgorithm.

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

Reimplemented from vtkDataSetAlgorithm.

void vtkIdFilter::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 vtkDataSetAlgorithm.

static vtkIdFilter* vtkIdFilter::New (  )  [static]

Construct object with PointIds and CellIds on; and ids being generated as scalars.

Reimplemented from vtkDataSetAlgorithm.

virtual void vtkIdFilter::SetPointIds ( int   )  [virtual]

Enable/disable the generation of point ids.

virtual int vtkIdFilter::GetPointIds (  )  [virtual]

Enable/disable the generation of point ids.

virtual void vtkIdFilter::PointIdsOn (  )  [virtual]

Enable/disable the generation of point ids.

virtual void vtkIdFilter::PointIdsOff (  )  [virtual]

Enable/disable the generation of point ids.

virtual void vtkIdFilter::SetCellIds ( int   )  [virtual]

Enable/disable the generation of point ids.

virtual int vtkIdFilter::GetCellIds (  )  [virtual]

Enable/disable the generation of point ids.

virtual void vtkIdFilter::CellIdsOn (  )  [virtual]

Enable/disable the generation of point ids.

virtual void vtkIdFilter::CellIdsOff (  )  [virtual]

Enable/disable the generation of point ids.

virtual void vtkIdFilter::SetFieldData ( int   )  [virtual]

Set/Get the flag which controls whether to generate scalar data or field data. If this flag is off, scalar data is generated. Otherwise, field data is generated.

virtual int vtkIdFilter::GetFieldData (  )  [virtual]

Set/Get the flag which controls whether to generate scalar data or field data. If this flag is off, scalar data is generated. Otherwise, field data is generated.

virtual void vtkIdFilter::FieldDataOn (  )  [virtual]

Set/Get the flag which controls whether to generate scalar data or field data. If this flag is off, scalar data is generated. Otherwise, field data is generated.

virtual void vtkIdFilter::FieldDataOff (  )  [virtual]

Set/Get the flag which controls whether to generate scalar data or field data. If this flag is off, scalar data is generated. Otherwise, field data is generated.

virtual void vtkIdFilter::SetIdsArrayName ( const char *   )  [virtual]

Set/Get the name of the Ids array if generated. By default the Ids are named "vtkIdFilter_Ids", but this can be changed with this function.

virtual char* vtkIdFilter::GetIdsArrayName (  )  [virtual]

Set/Get the name of the Ids array if generated. By default the Ids are named "vtkIdFilter_Ids", but this can be changed with this function.

int vtkIdFilter::RequestData ( vtkInformation ,
vtkInformationVector **  ,
vtkInformationVector  
) [protected, virtual]

This is called within ProcessRequest when a request asks the algorithm to do its work. This is the method you should override to do whatever the algorithm is designed to do. This happens during the fourth pass in the pipeline execution process.

Reimplemented from vtkDataSetAlgorithm.
