Detailed Description

abstract class to quickly locate points in 3-space

vtkAbstractPointLocator is an abstract spatial search object to quickly locate points in 3D. vtkAbstractPointLocator works by dividing a specified region of space into "rectangular" buckets, and then keeping a list of points that lie in each bucket. Typical operation involves giving a position in 3D and finding the closest point. The points are provided from the specified dataset input.

virtual vtkIdType vtkAbstractPointLocator::FindClosestPoint ( const double x[3] )

pure virtual

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.

Implemented in vtkIncrementalOctreePointLocator, vtkOctreePointLocator, vtkStaticPointLocator, vtkPointLocator, and vtkKdTreePointLocator.

vtkIdType vtkAbstractPointLocator::FindClosestPoint	(	double	x,
		double	y,
		double	z
	)

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.

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

pure virtual

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.

Implemented in vtkIncrementalOctreePointLocator, vtkOctreePointLocator, vtkStaticPointLocator, vtkPointLocator, and vtkKdTreePointLocator.

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

pure virtual

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.

Implemented in vtkIncrementalOctreePointLocator, vtkPointLocator, vtkOctreePointLocator, vtkStaticPointLocator, and vtkKdTreePointLocator.

void vtkAbstractPointLocator::FindClosestNPoints	(	int	N,
		double	x,
		double	y,
		double	z,
		vtkIdList *	result
	)

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.

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

pure virtual

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.

Implemented in vtkIncrementalOctreePointLocator, vtkPointLocator, vtkOctreePointLocator, vtkStaticPointLocator, and vtkKdTreePointLocator.

void vtkAbstractPointLocator::FindPointsWithinRadius	(	double	R,
