Detailed Description

subset a vtkDataSet to create a vtkUnstructuredGrid

Given a vtkDataSet and a list of cell ids, create a vtkUnstructuredGrid composed of these cells. If the cell list is empty when vtkExtractCells executes, it will set up the ugrid, point and cell arrays, with no points, cells or data.

Warning

This class is templated. It may run slower than serial execution if the code is not optimized during compilation. Build in Release or ReleaseWithDebugInfo.

This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.

SetCellList()

void vtkExtractCells::SetCellList

(

vtkIdList *

l

)

Set the list of cell IDs that the output vtkUnstructuredGrid will be composed of.

Replaces any other cell ID list supplied so far. (Set to nullptr to free memory used by cell list.) The cell ids should be >=0.

AddCellList()

void vtkExtractCells::AddCellList

(

vtkIdList *

l

)

Add the supplied list of cell IDs to those that will be included in the output vtkUnstructuredGrid.

The cell ids should be >=0.

AddCellRange()

void vtkExtractCells::AddCellRange	(	vtkIdType	from,
		vtkIdType	to
	)

Add this range of cell IDs to those that will be included in the output vtkUnstructuredGrid.

Note that (from < to), and (from >= 0).

SetCellIds()

void vtkExtractCells::SetCellIds	(	const vtkIdType *	ptr,

		vtkIdType	numValues
	)

Another way to provide ids using a pointer to vtkIdType array.

SetExtractAllCells()

virtual void vtkExtractCells::SetExtractAllCells ( bool  )

virtual

If all cells are being extracted, this filter can use fast path to speed up the extraction.

In that case, one can set this flag to true. When set to true, cell ids added via the various methods are simply ignored. Defaults to false.

GetExtractAllCells()

virtual bool vtkExtractCells::GetExtractAllCells ( )

virtual

If all cells are being extracted, this filter can use fast path to speed up the extraction.

In that case, one can set this flag to true. When set to true, cell ids added via the various methods are simply ignored. Defaults to false.

ExtractAllCellsOn()

virtual void vtkExtractCells::ExtractAllCellsOn ( )

If all cells are being extracted, this filter can use fast path to speed up the extraction.

In that case, one can set this flag to true. When set to true, cell ids added via the various methods are simply ignored. Defaults to false.

ExtractAllCellsOff()

virtual void vtkExtractCells::ExtractAllCellsOff ( )

If all cells are being extracted, this filter can use fast path to speed up the extraction.

In that case, one can set this flag to true. When set to true, cell ids added via the various methods are simply ignored. Defaults to false.

SetAssumeSortedAndUniqueIds()

virtual void vtkExtractCells::SetAssumeSortedAndUniqueIds ( bool  )

virtual

If the cell ids specified are already sorted and unique, then set this to true to avoid the filter from doing time-consuming sorts and uniquification operations.

Defaults to false.

GetAssumeSortedAndUniqueIds()

virtual bool vtkExtractCells::GetAssumeSortedAndUniqueIds ( )

virtual

If the cell ids specified are already sorted and unique, then set this to true to avoid the filter from doing time-consuming sorts and uniquification operations.

SetBatchSize()

virtual void vtkExtractCells::SetBatchSize ( unsigned int  )

virtual

Specify the number of input cells in a batch, where a batch defines a subset of the input cells operated on during threaded execution.

Generally this is only used for debugging or performance studies (since batch size affects the thread workload).

Default is 1000.

GetBatchSize()

virtual unsigned int vtkExtractCells::GetBatchSize ( )

virtual

Specify the number of input cells in a batch, where a batch defines a subset of the input cells operated on during threaded execution.

FillInputPortInformation()

int vtkExtractCells::FillInputPortInformation ( int  port, vtkInformation *  info  )
