Detailed Description

tessellates generic, higher-order datasets into linear cells

vtkGenericDataSetTessellator is a filter that subdivides a vtkGenericDataSet into linear elements (i.e., linear VTK cells). Tetrahedras are produced from 3D cells; triangles from 2D cells; and lines from 1D cells. The subdivision process depends on the cell tessellator associated with the input generic dataset, and its associated error metric. (These can be specified by the user if necessary.)

This filter is typically used to convert a higher-order, complex dataset represented by a vtkGenericDataSet into a conventional vtkDataSet that can be operated on by linear VTK graphics filters (end of pipeline for rendering).

virtual void vtkGenericDataSetTessellator::SetKeepCellIds ( int )

virtual

Turn on/off generation of a cell centered attribute with ids of the original cells (as an input cell is tessellated into several linear cells). The name of the data array is "OriginalIds". It is true by default.

virtual int vtkGenericDataSetTessellator::GetKeepCellIds ( )

virtual

Turn on/off generation of a cell centered attribute with ids of the original cells (as an input cell is tessellated into several linear cells). The name of the data array is "OriginalIds". It is true by default.

virtual void vtkGenericDataSetTessellator::KeepCellIdsOn ( )

virtual

Turn on/off generation of a cell centered attribute with ids of the original cells (as an input cell is tessellated into several linear cells). The name of the data array is "OriginalIds". It is true by default.

virtual void vtkGenericDataSetTessellator::KeepCellIdsOff ( )

virtual

Turn on/off generation of a cell centered attribute with ids of the original cells (as an input cell is tessellated into several linear cells). The name of the data array is "OriginalIds". It is true by default.

virtual void vtkGenericDataSetTessellator::SetMerging ( int )

virtual

Turn on/off merging of coincident points. Note that is merging is on, points with different point attributes (e.g., normals) are merged, which may cause rendering artifacts.

virtual int vtkGenericDataSetTessellator::GetMerging ( )

virtual

Turn on/off merging of coincident points. Note that is merging is on, points with different point attributes (e.g., normals) are merged, which may cause rendering artifacts.

virtual void vtkGenericDataSetTessellator::MergingOn ( )

virtual

Turn on/off merging of coincident points. Note that is merging is on, points with different point attributes (e.g., normals) are merged, which may cause rendering artifacts.

virtual void vtkGenericDataSetTessellator::MergingOff ( )

virtual

Turn on/off merging of coincident points. Note that is merging is on, points with different point attributes (e.g., normals) are merged, which may cause rendering artifacts.

void vtkGenericDataSetTessellator::SetLocator ( vtkIncrementalPointLocator * locator )

Set / get a spatial locator for merging points. By default an instance of vtkMergePoints is used.

virtual vtkIncrementalPointLocator* vtkGenericDataSetTessellator::GetLocator ( )

virtual

Set / get a spatial locator for merging points. By default an instance of vtkMergePoints is used.

void vtkGenericDataSetTessellator::CreateDefaultLocator ( )

Create default locator. Used to create one when none is specified.

unsigned long vtkGenericDataSetTessellator::GetMTime ( )

virtual

Return the MTime also considering the locator.

Reimplemented from vtkObject.

int vtkGenericDataSetTessellator::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)

protectedvirtual

This is called by the superclass. This is the method you should override.

Reimplemented from vtkUnstructuredGridAlgorithm.

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

protectedvirtual

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.
