Detailed Description

quickly locate points in 3-space

vtkStaticPointLocator is a spatial search object to quickly locate points in 3D. vtkStaticPointLocator works by dividing a specified region of space into a regular array of cuboid 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; or finding the N closest points.

vtkStaticPointLocator is an accelerated version of vtkPointLocator. It is threaded (via vtkSMPTools), and supports one-time static construction (i.e., incremental point insertion is not supported). If you need to incrementally insert points, use the vtkPointLocator or its kin to do so.

Warning: This class is templated. It may run slower than serial execution if the code is not optimized during compilation. Build in Release or ReleaseWithDebugInfo.; Make sure that you review the documentation for the superclasses vtkAbstactPointLocator and vtkLocator. In particular the Automatic data member can be used to automatically determine divisions based on the average number of points per bucket.; Other types of spatial locators have been developed such as octrees and kd-trees. These are often more efficient for the operations described here.

Specify the average number of points in each bucket.

This data member is used in conjunction with the Automatic data member (if enabled) to determine the number of locator x-y-z divisions.

virtual int vtkStaticPointLocator::GetNumberOfPointsPerBucket ( )

virtual

Specify the average number of points in each bucket.

This data member is used in conjunction with the Automatic data member (if enabled) to determine the number of locator x-y-z divisions.

Set the number of divisions in x-y-z directions.

If the Automatic data member is enabled, the Divisions are set according to the NumberOfPointsPerBucket and MaxNumberOfBuckets data members. The number of divisions must be >= 1 in each direction.

virtual void vtkStaticPointLocator::SetDivisions ( int [3] )

Set the number of divisions in x-y-z directions.

If the Automatic data member is enabled, the Divisions are set according to the NumberOfPointsPerBucket and MaxNumberOfBuckets data members. The number of divisions must be >= 1 in each direction.

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

overridevirtual

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

An alternative method (defined in the superclass) 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 vtkStaticPointLocator::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. Note that if multiple points are located the same distance away, the actual point returned is a function in which order the points are processed (i.e., indeterminate).

Implements vtkAbstractPointLocator.

virtual vtkIdType vtkStaticPointLocator::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. Note that if multiple points are located the same distance away, the actual point returned is a function in which order the points are processed (i.e., indeterminate).

void vtkStaticPointLocator::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 vtkStaticPointLocator::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.

int vtkStaticPointLocator::IntersectWithLine	(	double	a0[3],
		double	a1[3],
		double	tol,
		double &	t,
		double	lineX[3],
		double	ptX[3],
		vtkIdType &	ptId
	)

Intersect the points contained in the locator with the line defined by (a0,a1).

Return the point within the tolerance tol that is closest to a0 (tol measured in the world coordinate system). If an intersection occurs (i.e., the method returns nonzero), then the parametric location along the line t, the closest position along the line lineX, and the coordinates of the picked ptId is returned in ptX. (This method is thread safe after the locator is built.)

void vtkStaticPointLocator::MergePoints	(	double	tol,
		vtkIdType *	mergeMap
	)

Merge points in the locator given a tolerance.

Return a merge map which represents the mapping of "concident" point ids to a single point. Note the number of points in the merge map is the number of points the locator was built with. The user is expected to pass in an allocated mergeMap.

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

overridevirtual

Populate a polydata with the faces of the bins that potentially contain cells.

Note that the level parameter has no effect on this method as there is no hierarchy built (i.e., uniform binning). Typically this is used for debugging.

Implements vtkLocator.

vtkIdType vtkStaticPointLocator::GetNumberOfPointsInBucket ( vtkIdType bNum )

Given a bucket number bNum between 0 <= bNum < this->GetNumberOfBuckets(), return the number of points found in the bucket.

void vtkStaticPointLocator::GetBucketIds	(	vtkIdType	bNum,
		vtkIdList *	bList
	)

Given a bucket number bNum between 0 <= bNum < this->GetNumberOfBuckets(), return a list of point ids contained within the bucket.

The user must provide an instance of vtkIdList to contain the result.

virtual void vtkStaticPointLocator::SetMaxNumberOfBuckets ( vtkIdType )

virtual

Set the maximum number of buckets in the locator.

By default the value is set to VTK_INT_MAX. Note that there are significant performance implications at work here. If the number of buckets is set very large (meaning > VTK_INT_MAX) then internal sorting may be performed using 64-bit integers (which is much slower than using a 32-bit int). Of course, memory requirements may dramatically increase as well. It is recommended that the default value be used; but for extremely large data it may be desired to create a locator with an exceptionally large number of buckets. Note also that during initialization of the locator if the MaxNumberOfBuckets threshold is exceeded, the Divisions are scaled down in such a way as not to exceed the MaxNumberOfBuckets proportionally to the size of the bounding box in the x-y-z directions.

virtual vtkIdType vtkStaticPointLocator::GetMaxNumberOfBuckets ( )

virtual

Set the maximum number of buckets in the locator.

By default the value is set to VTK_INT_MAX. Note that there are significant performance implications at work here. If the number of buckets is set very large (meaning > VTK_INT_MAX) then internal sorting may be performed using 64-bit integers (which is much slower than using a 32-bit int).

Note also that during initialization of the locator if the MaxNumberOfBuckets threshold is exceeded, the Divisions are scaled down in such a way as not to exceed the MaxNumberOfBuckets proportionally to the size of the bounding box in the x-y-z directions.

bool vtkStaticPointLocator::GetLargeIds ( )

inline

Inform the user as to whether large ids are being used.

This flag only has meaning after the locator has been built. Large ids are used when the number of binned points, or the number of bins, is >= the maximum number of buckets (specified by the user). Note that LargeIds are only available on 64-bit architectures.
