Usage
To create an instance of class vtkKdNode, simply invoke its
constructor as follows
obj = vtkKdNode
Methods
The class vtkKdNode has several methods that can be used.
They are listed below. Note that the documentation is
translated automatically from the VTK sources, and may not
be completely intelligible. When in doubt, consult the VTK
website. In the methods listed below, obj is an instance of
the vtkKdNode class.
* string = obj.GetClassName ()
* int = obj.IsA (string name)
* vtkKdNode = obj.NewInstance ()
* vtkKdNode = obj.SafeDownCast (vtkObject o)

region is divided. (0 - x, 1 - y, 2 - z, 3 - leaf node
(default)).
* int = obj.GetDim () - Set/Get the dimension along which
this region is divided. (0 - x, 1 - y, 2 - z, 3 - leaf
node (default)).
* double = obj.GetDivisionPosition () - Get the location of

the bounds of these points.

* double = obj.GetMaxDataBounds () - Set the xmin, ymin and
zmin value of the bounds of this data within this region
* obj.SetMinDataBounds (double mb) - Set the xmin, ymin and
zmin value of the bounds of this data within this region
* obj.SetMaxDataBounds (double mb) - Set the xmax, ymax and
zmax value of the bounds of this data within this region
* obj.SetID (int ) - Set/Get the ID associated with the
region described by this node. If this is not a leaf node,
this value should be -1.
* int = obj.GetID () - Set/Get the ID associated with the
region described by this node. If this is not a leaf node,
this value should be -1.
* int = obj.GetMinID () - If this node is not a leaf node,
there are leaf nodes below it whose regions represent a
partitioning of this region. The IDs of these leaf nodes
form a contigous set. Set/Get the range of the IDs of the
leaf nodes below this node. If this is already a leaf
node, these values should be the same as the ID.
* int = obj.GetMaxID () - If this node is not a leaf node,
there are leaf nodes below it whose regions represent a
partitioning of this region. The IDs of these leaf nodes
form a contigous set. Set/Get the range of the IDs of the
leaf nodes below this node. If this is already a leaf
node, these values should be the same as the ID.
* obj.SetMinID (int ) - If this node is not a leaf node,
there are leaf nodes below it whose regions represent a
partitioning of this region. The IDs of these leaf nodes
form a contigous set. Set/Get the range of the IDs of the
leaf nodes below this node. If this is already a leaf
node, these values should be the same as the ID.
* obj.SetMaxID (int ) - If this node is not a leaf node,
there are leaf nodes below it whose regions represent a
partitioning of this region. The IDs of these leaf nodes
form a contigous set. Set/Get the range of the IDs of the
leaf nodes below this node. If this is already a leaf
node, these values should be the same as the ID.
* obj.AddChildNodes (vtkKdNode left, vtkKdNode right) - Add
the left and right children.
* obj.DeleteChildNodes () - Delete the left and right
children.
* vtkKdNode = obj.GetLeft () - Set/Get a pointer to the left
child of this node.
* obj.SetLeft (vtkKdNode left) - Set/Get a pointer to the
left child of this node.
* vtkKdNode = obj.GetRight () - Set/Get a pointer to the
right child of this node.
* obj.SetRight (vtkKdNode right) - Set/Get a pointer to the
right child of this node.
* vtkKdNode = obj.GetUp () - Set/Get a pointer to the parent
of this node.
* obj.SetUp (vtkKdNode up) - Set/Get a pointer to the parent
of this node.
* int = obj.IntersectsBox (double x1, double x2, double y1,
double y2, double z1, double z2, int useDataBounds) -
Return 1 if this spatial region intersects the axis-
aligned box given by the bounds passed in. Use the
possibly smaller bounds of the points within the region if
useDataBounds is non-zero.
* int = obj.IntersectsSphere2 (double x, double y, double z,
double rSquared, int useDataBounds) - Return 1 if this
spatial region intersects a sphere described by it's
center and the square of it's radius. Use the possibly
smaller bounds of the points within the region if
useDataBounds is non-zero.
* int = obj.IntersectsRegion (vtkPlanesIntersection pi, int
useDataBounds) - A vtkPlanesIntersection object represents
a convex 3D region bounded by planes, and it is capable of
computing intersections of boxes with itself. Return 1 if
this spatial region intersects the spatial region
described by the vtkPlanesIntersection object. Use the
possibly smaller bounds of the points within the region if
useDataBounds is non-zero.
* int = obj.IntersectsCell (vtkCell cell, int useDataBounds,
int cellRegion, double cellBoundsNULL) - Return 1 if the
cell specified intersects this region. If you already know
the ID of the region containing the cell's centroid,
provide that as an argument. If you already know the
bounds of the cell, provide that as well, in the form of
xmin,xmax,ymin,ymax,zmin, zmax. Either of these may speed
the calculation. Use the possibly smaller bounds of the
points within the region if useDataBounds is non-zero.
* int = obj.ContainsBox (double x1, double x2, double y1,
double y2, double z1, double z2, int useDataBounds) -
Return 1 if this spatial region entirely contains a box
specified by it's bounds. Use the possibly smaller bounds
of the points within the region if useDataBounds is non-
zero.
* int = obj.ContainsPoint (double x, double y, double z, int
useDataBounds) - Return 1 if this spatial region entirely
contains the given point. Use the possibly smaller bounds
of the points within the region if useDataBounds is non-
zero.
* double = obj.GetDistance2ToBoundary (double x, double y,
double z, int useDataBounds) - Calculate the distance
squared from any point to the boundary of this region. Use
the boundary of the points within the region if
useDataBounds is non-zero.
* double = obj.GetDistance2ToBoundary (double x, double y,
double z, double boundaryPt, int useDataBounds) -
Calculate the distance squared from any point to the
boundary of this region. Use the boundary of the points
within the region if useDataBounds is non-zero. Set
boundaryPt to the point on the boundary.
* double = obj.GetDistance2ToInnerBoundary (double x, double
y, double z) - Calculate the distance from the specified
point (which is required to be inside this spatial region)
to an interior boundary. An interior boundary is one that
is not also an boundary of the entire space partitioned by
the tree of vtkKdNode's.
* obj.PrintNode (int depth) - For debugging purposes, print
out this node.
* obj.PrintVerboseNode (int depth) - For debugging purposes,
print out this node.
