vtkBSPCuts Class Reference
#include <vtkBSPCuts.h>
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.

Reimplemented from vtkObject.
| static int vtkBSPCuts::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeRevisionMacro found in vtkSetGet.h.

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, | |||

| ) |
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.
