Detailed Description

This filter is a concrete instance of vtkMultiBlockDataSetAlgorithm and provides functionality for extracting portion of the AMR dataset, specified by a bounding box, in a uniform grid of the desired level of resolution.

The resulting uniform grid is stored in a vtkMultiBlockDataSet where the number of blocks correspond to the number of processors utilized for the operation.

Warning: Data of the input AMR dataset is assumed to be cell-centered.

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.
