// .NAME vtkExtractRectilinearGrid - Extract a sub grid (VOI) from the structured rectilinear dataset.
|
|
// .SECTION Description
|
|
// vtkExtractRectilinearGrid rounds out the set of filters that extract
|
|
// a subgrid out of a larger structured data set. RIght now, this filter
|
|
// only supports extracting a VOI. In the future, it might support
|
|
// strides like the vtkExtract grid filter.

// on, the subsampling will always include the boundary of the grid even
|

// though the sample rate is not an even multiple of the grid
