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.

	)

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.

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,

		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.
