Detailed Description

clip volume data with user-specified implicit function or input scalar data

vtkClipVolume is a filter that clips volume data (i.e., vtkImageData) using either: any subclass of vtkImplicitFunction or the input scalar data. The clipping operation cuts through the cells of the dataset–converting 3D image data into a 3D unstructured grid–returning everything inside of the specified implicit function (or greater than the scalar value). During the clipping the filter will produce pieces of a cell. (Compare this with vtkExtractGeometry or vtkGeometryFilter, which produces entire, uncut cells.) The output of this filter is a 3D unstructured grid (e.g., tetrahedra or other 3D cell types).

To use this filter, you must decide if you will be clipping with an implicit function, or whether you will be using the input scalar data. If you want to clip with an implicit function, you must first define and then set the implicit function with the SetClipFunction() method. Otherwise, you must make sure input scalar data is available. You can also specify a scalar value, which is used to decide what is inside and outside of the implicit function. You can also reverse the sense of what inside/outside is by setting the InsideOut instance variable. (The cutting algorithm proceeds by computing an implicit function value or using the input scalar data for each point in the dataset. This is compared to the scalar value to determine inside/outside.)

This filter can be configured to compute a second output. The second output is the portion of the volume that is clipped away. Set the GenerateClippedData boolean on if you wish to access this output data.

The filter will produce an unstructured grid of entirely tetrahedra or a mixed grid of tetrahedra and other 3D cell types (e.g., wedges). Control this behavior by setting the Mixed3DCellGeneration. By default the Mixed3DCellGeneration is on and a combination of cell types will be produced. Note that producing mixed cell types is a faster than producing only tetrahedra.

Warning: This filter is designed to function with 3D structured points. Clipping 2D images should be done by converting the image to polygonal data and using vtkClipPolyData,

virtual void vtkClipVolume::GenerateClipScalarsOn ( )

virtual

◆ GenerateClipScalarsOff()

virtual void vtkClipVolume::GenerateClipScalarsOff ( )

virtual

◆ SetGenerateClippedOutput()

virtual void vtkClipVolume::SetGenerateClippedOutput ( vtkTypeBool )

virtual

Control whether a second output is generated.

The second output contains the unstructured grid that's been clipped away.

◆ GetGenerateClippedOutput()

virtual vtkTypeBool vtkClipVolume::GetGenerateClippedOutput ( )

virtual

◆ GenerateClippedOutputOn()

virtual void vtkClipVolume::GenerateClippedOutputOn ( )

virtual

◆ GenerateClippedOutputOff()

virtual void vtkClipVolume::GenerateClippedOutputOff ( )

virtual

◆ GetClippedOutput()

vtkUnstructuredGrid* vtkClipVolume::GetClippedOutput ( )

Return the clipped output.

◆ SetMixed3DCellGeneration()

virtual void vtkClipVolume::SetMixed3DCellGeneration ( vtkTypeBool )

virtual

Control whether the filter produces a mix of 3D cell types on output, or whether the output cells are all tetrahedra.

By default, a mixed set of cells (e.g., tetrahedra and wedges) is produced. (Note: mixed type generation is faster and less overall data is generated.)

◆ GetMixed3DCellGeneration()

virtual vtkTypeBool vtkClipVolume::GetMixed3DCellGeneration ( )

virtual

◆ Mixed3DCellGenerationOn()

virtual void vtkClipVolume::Mixed3DCellGenerationOn ( )

virtual

◆ Mixed3DCellGenerationOff()

virtual void vtkClipVolume::Mixed3DCellGenerationOff ( )

virtual

◆ SetMergeTolerance()

virtual void vtkClipVolume::SetMergeTolerance ( double )

virtual

Set the tolerance for merging clip intersection points that are near the corners of voxels.

This tolerance is used to prevent the generation of degenerate tetrahedra.

◆ GetMergeTolerance()

virtual double vtkClipVolume::GetMergeTolerance ( )

virtual

◆ SetLocator()

void vtkClipVolume::SetLocator ( vtkIncrementalPointLocator * locator )

Set / Get a spatial locator for merging points.

By default, an instance of vtkMergePoints is used.

◆ GetLocator()

virtual vtkIncrementalPointLocator* vtkClipVolume::GetLocator ( )

virtual

◆ CreateDefaultLocator()

void vtkClipVolume::CreateDefaultLocator ( )

Create default locator.

Used to create one when none is specified. The locator is used to merge coincident points.

◆ GetMTime()

vtkMTimeType vtkClipVolume::GetMTime ( )

overridevirtual

Return the mtime also considering the locator and clip function.

Reimplemented from vtkObject.

◆ ReportReferences()

void vtkClipVolume::ReportReferences ( vtkGarbageCollector * )

overrideprotectedvirtual

Reimplemented from vtkAlgorithm.

◆ RequestData()

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

overrideprotectedvirtual

This is called by the superclass.

This is the method you should override.

Reimplemented from vtkUnstructuredGridAlgorithm.

◆ FillInputPortInformation()

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

overrideprotectedvirtual

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 vtkUnstructuredGridAlgorithm.

void vtkClipVolume::ClipTets	(	double	value,
		vtkTetra *	clipTetra,
		vtkDataArray *	clipScalars,
		vtkDataArray *	cellScalars,
		vtkIdList *	tetraIds,
		vtkPoints *	tetraPts,

◆ ClipVoxel()

void vtkClipVolume::ClipVoxel	(	double	value,
		vtkDataArray *	cellScalars,
		int	flip,
		double	origin[3],
		double	spacing[3],
		vtkIdList *	cellIds,
		vtkPoints *	cellPts,
