Build a k-d tree decomposition of a list of points.
<p>
Build, in parallel, a k-d tree decomposition of one or more vtkDataSets distributed across processors. We assume each process has read in one portion of a large distributed data set. When done, each process has access to the k-d tree structure, can obtain information about which process contains data for each spatial region, and can depth sort the spatial regions.<p>
This class can also assign spatial regions to processors, based on one of several region assignment schemes. By default a contiguous, convex region is assigned to each process. Several queries return information about how many and what cells I have that lie in a region assigned to another process.<p>

The k-d tree spatial regions have been assigned to processes.

After regions have been assigned to processes, I may want to know which cells I have that are in the regions assigned to a particular process. This method takes a process ID and two vtkIdLists. It writes to the first list the IDs of the cells contained in the process' regions. (That is, their cell centroid is contained in the region.) To the second list it write the IDs of the cells which intersect the process' regions but whose cell centroid lies elsewhere. The total number of cell IDs written to both lists is returned. Either list pointer passed in can be NULL, and it will be ignored. If there are multiple data sets, you must specify which data set you wish cell IDs for. The caller should delete these two lists when done. This method uses the cell lists created in <a class="el" href="a00933.html#40ec299fcb6a8ad1d036c17f9858a3c5">vtkKdTree::CreateCellLists()</a>.
