overridevirtual

Standard type and print methods.

Reimplemented from vtkAbstractPointLocator.

vtkIdType vtkKdTreePointLocator::FindClosestPoint ( const double x[3] )

overridevirtual

Given a position x, return the id of the point closest to it.

Alternative method requires separate x-y-z values. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

Implements vtkAbstractPointLocator.

vtkIdType vtkKdTreePointLocator::FindClosestPointWithinRadius	(	double	radius,
		const double	x[3],
		double &	dist2
	)

overridevirtual

Given a position x and a radius r, return the id of the point closest to the point in that radius.

dist2 returns the squared distance to the point.

Implements vtkAbstractPointLocator.

void vtkKdTreePointLocator::FindClosestNPoints	(	int	N,
		const double	x[3],
		vtkIdList *	result
	)

overridevirtual

Find the closest N points to a position.

This returns the closest N points to a position. A faster method could be created that returned N close points to a position, but necessarily the exact N closest. The returned points are sorted from closest to farthest. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

Implements vtkAbstractPointLocator.

void vtkKdTreePointLocator::FindPointsWithinRadius	(	double	R,
		const double	x[3],
		vtkIdList *	result
	)

overridevirtual

Find all points within a specified radius R of position x.

The result is not sorted in any specific manner. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

Implements vtkAbstractPointLocator.

void vtkKdTreePointLocator::FreeSearchStructure ( )

overridevirtual

See vtkLocator interface documentation.

These methods are not thread safe.

Implements vtkLocator.

void vtkKdTreePointLocator::BuildLocator ( )

overridevirtual

See vtkLocator interface documentation.

These methods are not thread safe.

Implements vtkLocator.

void vtkKdTreePointLocator::GenerateRepresentation	(	int	level,
		vtkPolyData *	pd
	)

overridevirtual

See vtkLocator interface documentation.

These methods are not thread safe.

Implements vtkLocator.
