Detailed Description

a Kd-tree spatial decomposition of a set of points

Given one or more vtkDataSets, create a load balancing
k-d tree decomposition of the points at the center of the cells.
Or, create a k-d tree point locator from a list of points.

This class can also generate a PolyData representation of
the boundaries of the spatial regions in the decomposition.

It can sort the regions with respect to a viewing direction,
and it can decompose a list of regions into subsets, each
of which represent a convex spatial region (since many algorithms
require a convex region).

If the points were derived from cells, vtkKdTree
can create a list of cell Ids for each region for each data set.
Two lists are available - all cells with centroid in the region,
and all cells that intersect the region but whose centroid lies
in another region.

For the purpose of removing duplicate points quickly from large
data sets, or for finding nearby points, we added another mode for
building the locator.  BuildLocatorFromPoints will build a k-d tree
from one or more vtkPoints objects.  This can be followed by
BuildMapForDuplicatePoints which returns a mapping from the original
ids to a subset of the ids that is unique within a supplied
tolerance, or you can use FindPoint and FindClosestPoint to
locate points in the original set that the tree was built from.

	)

Create a list for each of the requested regions, listing the IDs of all cells whose centroid falls in the region.

These lists are obtained with GetCellList(). If no DataSet is specified, the cell list is created for DataSet 0. If no list of requested regions is provided, the cell lists for all regions are created.

◆ GetBoundaryCellList()

vtkIdList * vtkKdTree::GetBoundaryCellList ( int regionID )

The cell list obtained with GetCellList is the list of all cells such that their centroid is contained in the spatial region.

It may also be desirable to get a list of all cells intersecting a spatial region, but with centroid in some other region. This is that list. This list is computed in CreateCellLists() if and only if IncludeRegionBoundaryCells is ON. This returns a pointer to KdTree's memory, so don't free it.

◆ GetCellLists() [1/3]

vtkIdType vtkKdTree::GetCellLists	(	vtkIntArray *	regions,
		int	set,
		vtkIdList *	inRegionCells,
		vtkIdList *	onBoundaryCells
	)

For a list of regions, get two cell lists.

The first lists the IDs all cells whose centroids lie in one of the regions. The second lists the IDs of all cells that intersect the regions, but whose centroid lies in a region not on the list.

The total number of cell IDs written to both lists is returned. Either list pointer passed in can be nullptr, and it will be ignored. If there are multiple data sets, you must specify which data set you wish cell IDs for.

The caller should delete these two lists when done. This method uses the cell lists created in CreateCellLists(). If the cell list for any of the requested regions does not exist, then this method will call CreateCellLists() to create cell lists for every region of the k-d tree. You must remember to DeleteCellLists() when done with all calls to this method, as cell lists can require a great deal of memory.

◆ GetCellLists() [2/3]

The caller should delete these two lists when done. This method uses the cell lists created in CreateCellLists(). If the cell list for any of the requested regions does not exist, then this method will call CreateCellLists() to create cell lists for every region of the k-d tree. You must remember to DeleteCellLists() when done with all calls to this method, as cell lists can require a great deal of memory.

◆ AllGetRegionContainingCell()

int * vtkKdTree::AllGetRegionContainingCell ( )

Get a list (in order by data set by cell id) of the region IDs of the region containing the centroid for each cell.

This is faster than calling GetRegionContainingCell for each cell in the DataSet. vtkKdTree uses this list, so don't delete it.

		double	y,
		double	z
	)

Get the id of the region containing the specified location.

int vtkKdTree::MinimalNumberOfConvexSubRegions	(	vtkIntArray *	regionIdList,
		double **	convexRegionBounds
	)

Given a list of region IDs, determine the decomposition of these regions into the minimal number of convex subregions.

Due to the way the k-d tree is constructed, those convex subregions will be axis-aligned boxes. Return the minimal number of such convex regions that compose the original region list. This call will set convexRegionBounds to point to a list of the bounds of these regions. Caller should free this. There will be six values for each convex subregion (xmin, xmax, ymin, ymax, zmin, zmax). If the regions in the regionIdList form a box already, a "1" is returned and the second argument contains the bounds of the box.

◆ BuildLocatorFromPoints() [1/3]

void vtkKdTree::BuildLocatorFromPoints ( vtkPointSet * pointset )

This is a special purpose locator that builds a k-d tree to find duplicate and near-by points.

It builds the tree from one or more vtkPoints objects instead of from the cells of a vtkDataSet. This build would normally be followed by BuildMapForDuplicatePoints, FindPoint, or FindClosestPoint. Since this will build a normal k-d tree, all the region intersection queries will still work, as will most other calls except those that have "Cell" in the name.

This method works most efficiently when the point arrays are float arrays.

◆ BuildLocatorFromPoints() [2/3]

void vtkKdTree::BuildLocatorFromPoints ( vtkPoints * ptArray )

This is a special purpose locator that builds a k-d tree to find duplicate and near-by points.

It builds the tree from one or more vtkPoints objects instead of from the cells of a vtkDataSet. This build would normally be followed by BuildMapForDuplicatePoints, FindPoint, or FindClosestPoint. Since this will build a normal k-d tree, all the region intersection queries will still work, as will most other calls except those that have "Cell" in the name.

This method works most efficiently when the point arrays are float arrays.

This is a special purpose locator that builds a k-d tree to find duplicate and near-by points.

It builds the tree from one or more vtkPoints objects instead of from the cells of a vtkDataSet. This build would normally be followed by BuildMapForDuplicatePoints, FindPoint, or FindClosestPoint. Since this will build a normal k-d tree, all the region intersection queries will still work, as will most other calls except those that have "Cell" in the name.

This method works most efficiently when the point arrays are float arrays.

◆ BuildMapForDuplicatePoints()

vtkIdTypeArray * vtkKdTree::BuildMapForDuplicatePoints ( float tolerance )

This call returns a mapping from the original point IDs supplied to BuildLocatorFromPoints to a subset of those IDs that is unique within the specified tolerance.

If points 2, 5, and 12 are the same, then IdMap[2] = IdMap[5] = IdMap[12] = 2 (or 5 or 12).

"original point IDs" - For point IDs we start at 0 for the first point in the first vtkPoints object, and increase by 1 for subsequent points and subsequent vtkPoints objects.

You must have called BuildLocatorFromPoints() before calling this. You are responsible for deleting the returned array.

		const double	x[3],
		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.
