Detailed Description

This class represents an axis-aligned Binary Spatial Partitioning of a 3D space.

This class converts between the vtkKdTree representation of a tree of vtkKdNodes (used by vtkDistributedDataFilter) and a compact array representation that might be provided by a graph partitioning library like Zoltan. Such a representation could be used in message passing.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

void vtkBSPCuts::CreateCuts	(	double *	bounds,
		int	ncuts,
		int *	dim,
		double *	coord,
		int *	lower,
		int *	upper,
		double *	lowerDataCoord,
		double *	upperDataCoord,
		int *	npoints
	)

Initialize the cuts with arrays of information.

This type of information would be obtained from a graph partitioning software package like Zoltan.

bounds - the bounds (xmin, xmax, ymin, ymax, zmin, zmax) of the space being partitioned ncuts - the number cuts, also the size of the following arrays dim - the dimension along which the cut is made (x/y/z - 0/1/2) coord - the location of the cut along the axis lower - array index for the lower region bounded by the cut upper - array index for the upper region bounded by the cut lowerDataCoord - optional upper bound of the data in the lower region upperDataCoord - optional lower bound of the data in the upper region npoints - optional number of points in the spatial region

void vtkBSPCuts::CreateCuts

(

vtkKdNode *

kd

)

Initialize the cuts from a tree of vtkKdNode's.

vtkKdNode* vtkBSPCuts::GetKdNodeTree ( )

inline

Return a tree of vtkKdNode's representing the cuts specified in this object.

This is our copy, don't delete it.

Definition at line 85 of file vtkBSPCuts.h.

virtual int vtkBSPCuts::GetNumberOfCuts ( )

virtual

Get the number of cuts in the partitioning, which also the size of the arrays in the array representation of the partitioning.

int vtkBSPCuts::GetArrays	(	int	len,
		int *	dim,
		double *	coord,
		int *	lower,
		int *	upper,
		double *	lowerDataCoord,
		double *	upperDataCoord,
		int *	npoints
	)

Get the arrays representing the cuts in the partitioning.

int vtkBSPCuts::Equals	(	vtkBSPCuts *	other,
		double	tolerance = 0.0
	)

Compare these cuts with those of the other tree.

Returns true if the two trees are the same.
