Detailed Description

Extract cells from a hyper tree grid where selected scalar value is within given range.

This filter extracts cells from a hyper tree grid that satisfy the following contour: a cell is considered to be within range if its value for the active scalar is within a specified range (inclusive). The output is a vtkPolyData.

vtkHyperTreeGridContour* vtkHyperTreeGridContour::NewInstance ( ) const

void vtkHyperTreeGridContour::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)

overridevirtual

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 vtkHyperTreeGridAlgorithm.

void vtkHyperTreeGridContour::SetLocator ( vtkIncrementalPointLocator * )

Set / get a spatial locator for merging points.

By default, an instance of vtkMergePoints is used.

virtual vtkIncrementalPointLocator* vtkHyperTreeGridContour::GetLocator ( )

virtual

Set / get a spatial locator for merging points.

By default, an instance of vtkMergePoints is used.

void vtkHyperTreeGridContour::CreateDefaultLocator ( )

Create default locator.

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

vtkMTimeType vtkHyperTreeGridContour::GetMTime ( )

overridevirtual

Modified GetMTime Because we delegate to vtkContourValues.

Reimplemented from vtkObject.

void vtkHyperTreeGridContour::SetValue	(	int	i,
		double	value
	)

inline

Methods (inlined) to set / get contour values.

Set a particular contour value at contour number i.

The index i ranges between 0<=i<NumberOfContours.

Definition at line 182 of file vtkHyperTreeGridContour.h.

double vtkHyperTreeGridContour::GetValue ( int i )

inline

Get the ith contour value.

Definition at line 188 of file vtkHyperTreeGridContour.h.

double * vtkHyperTreeGridContour::GetValues ( )

inline

Get a pointer to an array of contour values.

There will be GetNumberOfContours() values in the list.

Definition at line 195 of file vtkHyperTreeGridContour.h.

void vtkHyperTreeGridContour::GetValues ( double * contourValues )

inline

Fill a supplied list with contour values.

There will be GetNumberOfContours() values in the list. Make sure you allocate enough memory to hold the list.

Definition at line 203 of file vtkHyperTreeGridContour.h.

void vtkHyperTreeGridContour::SetNumberOfContours ( int number )

inline

Set the number of contours to place into the list.

You only really need to use this method to reduce list size. The method SetValue() will automatically increase list size as needed.

Definition at line 211 of file vtkHyperTreeGridContour.h.

int vtkHyperTreeGridContour::GetNumberOfContours ( )

inline

Get the number of contours in the list of contour values.

Definition at line 217 of file vtkHyperTreeGridContour.h.

void vtkHyperTreeGridContour::GenerateValues	(	int	numContours,
		double	range[2]
	)

inline

Generate numContours equally spaced contour values between specified range.

Contour values will include min/max range values.

Definition at line 224 of file vtkHyperTreeGridContour.h.

void vtkHyperTreeGridContour::GenerateValues	(	int	numContours,
		double	rangeStart,
		double	rangeEnd
	)

inline

Generate numContours equally spaced contour values between specified range.

Contour values will include min/max range values.

int vtkHyperTreeGridContour::FillOutputPortInformation	(	int	,
		vtkInformation *
	)

overrideprotectedvirtual

For this algorithm the output is a vtkPolyData instance.

Reimplemented from vtkHyperTreeGridAlgorithm.

int vtkHyperTreeGridContour::ProcessTrees	(	vtkHyperTreeGrid *	,
		vtkDataObject *
	)

overrideprotectedvirtual

Main routine to generate isocontours of hyper tree grid.

Implements vtkHyperTreeGridAlgorithm.

bool vtkHyperTreeGridContour::RecursivelyPreProcessTree ( vtkHyperTreeGridCursor * )

protected

Recursively decide whether a cell is intersected by a contour.

void vtkHyperTreeGridContour::RecursivelyProcessTree	(	vtkHyperTreeGridCursor *	,
		vtkBitArray *
	)

protected

Recursively descend into tree down to leaves.
