Detailed Description

quickly locate points in 3-space

vtkPointLocator is a spatial search object to quickly locate points in 3D. vtkPointLocator works by dividing a specified region of space into a regular array of "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.

vtkPointLocator has two distinct methods of interaction. In the first method, you supply it with a dataset, and it operates on the points in the dataset. In the second method, you supply it with an array of points, and the object operates on the array.

Warning: Many other types of spatial locators have been developed such as octrees and kd-trees. These are often more efficient for the operations described here.

vtkIdType vtkPointLocator::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 vtkPointLocator::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.

These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first. dist2 returns the squared distance to the point.

Implements vtkAbstractPointLocator.

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

virtual

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

These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first. dist2 returns the squared distance to the point.

int vtkPointLocator::InitPointInsertion	(	vtkPoints *	newPts,
		const double	bounds[6]
	)

overridevirtual

Initialize the point insertion process.

The newPts is an object representing point coordinates into which incremental insertion methods place their data. Bounds are the box that the points lie in. Not thread safe.

Implements vtkIncrementalPointLocator.

int vtkPointLocator::InitPointInsertion	(	vtkPoints *	newPts,
		const double	bounds[6],
		vtkIdType	estSize
	)

overridevirtual

Initialize the point insertion process.

The newPts is an object representing point coordinates into which incremental insertion methods place their data. Bounds are the box that the points lie in. Not thread safe.

Implements vtkIncrementalPointLocator.

void vtkPointLocator::InsertPoint	(	vtkIdType	ptId,
		const double	x[3]
	)

overridevirtual

Incrementally insert a point into search structure with a particular index value.

You should use the method IsInsertedPoint() to see whether this point has already been inserted (that is, if you desire to prevent duplicate points). Before using this method you must make sure that newPts have been supplied, the bounds has been set properly, and that divs are properly set. (See InitPointInsertion().) Not thread safe.

Implements vtkIncrementalPointLocator.

vtkIdType vtkPointLocator::InsertNextPoint ( const double x[3] )

overridevirtual

Incrementally insert a point into search structure.

The method returns the insertion location (i.e., point id). You should use the method IsInsertedPoint() to see whether this point has already been inserted (that is, if you desire to prevent duplicate points). Before using this method you must make sure that newPts have been supplied, the bounds has been set properly, and that divs are properly set. (See InitPointInsertion().) Not thread safe.

Implements vtkIncrementalPointLocator.

vtkIdType vtkPointLocator::IsInsertedPoint	(	double	x,
		double	y,
		double	z
	)

inlineoverridevirtual

Determine whether point given by x[3] has been inserted into points list.

Return id of previously inserted point if this is true, otherwise return -1. This method is thread safe.

Implements vtkIncrementalPointLocator.

Definition at line 159 of file vtkPointLocator.h.

vtkIdType vtkPointLocator::IsInsertedPoint ( const double x[3] )

overridevirtual

Determine whether point given by x[3] has been inserted into points list.

Return id of previously inserted point if this is true, otherwise return -1. This method is thread safe.

Implements vtkIncrementalPointLocator.

int vtkPointLocator::InsertUniquePoint	(	const double	x[3],
		vtkIdType &	ptId
	)

overridevirtual

Determine whether point given by x[3] has been inserted into points list.

Return 0 if point was already in the list, otherwise return 1. If the point was not in the list, it will be ADDED. In either case, the id of the point (newly inserted or not) is returned in the ptId argument. Note this combines the functionality of IsInsertedPoint() followed by a call to InsertNextPoint(). This method is not thread safe.

Implements vtkIncrementalPointLocator.

vtkIdType vtkPointLocator::FindClosestInsertedPoint ( const double x[3] )

overridevirtual

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

This method is used when performing incremental point insertion. Note that -1 indicates that no point was found. This method is thread safe if BuildLocator() is directly or indirectly called from a single thread first.

Implements vtkIncrementalPointLocator.

void vtkPointLocator::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.

virtual void vtkPointLocator::FindDistributedPoints	(	int	N,
		const double	x[3],
		vtkIdList *	result,
		int	M
	)

virtual

Find the closest points to a position such that each octant of space around the position contains at least N points.

Loosely limit the search to a maximum number of points evaluated, M. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

virtual void vtkPointLocator::FindDistributedPoints	(	int	N,
		double	x,
		double	y,
		double	z,
		vtkIdList *	result,

	)

virtual

Find the closest points to a position such that each octant of space around the position contains at least N points.

Loosely limit the search to a maximum number of points evaluated, M. These methods are thread safe if BuildLocator() is directly or indirectly called from a single thread first.

void vtkPointLocator::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.

virtual vtkIdList* vtkPointLocator::GetPointsInBucket	(	const double	x[3],
		int	ijk[3]
	)

virtual

Given a position x, return the list of points in the bucket that contains the point.

It is possible that nullptr is returned. The user provides an ijk array that is the indices into the locator. This method is thread safe.
