/**
 * @class   vtkmExtractVOI
 * @brief   select piece (e.g., volume of interest) and/or subsample structured points dataset
 *
 * vtkmExtractVOI is a filter that selects a portion of an input structured
 * points dataset, or subsamples an input dataset. (The selected portion of
 * interested is referred to as the Volume Of Interest, or VOI.) The output of
 * this filter is a structured points dataset. The filter treats input data
 * of any topological dimension (i.e., point, line, image, or volume) and can
 * generate output data of any topological dimension.
 *
 * To use this filter set the VOI ivar which are i-j-k min/max indices that
 * specify a rectangular region in the data. (Note that these are 0-offset.)
 * You can also specify a sampling rate to subsample the data.
 *
 * Typical applications of this filter are to extract a slice from a volume
 * for image processing, subsampling large volumes to reduce data size, or
 * extracting regions of a volume with interesting data.
