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.

Member Function Documentation

virtual const char* vtkBSPCuts::GetClassName (   )  [virtual]

Reimplemented from vtkObject.

static int vtkBSPCuts::IsTypeOf (  const char *  type  )  [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. Reimplemented from vtkObject.

virtual int vtkBSPCuts::IsA (  const char *  type  )  [virtual]

Return 1 if this class 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. Reimplemented from vtkObject.

static vtkBSPCuts* vtkBSPCuts::SafeDownCast (  vtkObject *  o  )  [static]

Reimplemented from vtkObject.

void vtkBSPCuts::PrintSelf (  ostream &  os, vtkIndent  indent )  [virtual]

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.

static vtkBSPCuts* vtkBSPCuts::New (   )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on. 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 75 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.
