vtkExtractGrid - select piece (e.g., volume of interest) and/or subsample structured grid dataset
Super Class: vtkStructuredGridToStructuredGridFilter
Description:
vtkExtractGrid is a filter that selects a portion of an input structured grid dataset, or subsamples an input dataset. (The selected portion of interested is referred toas the Volume Of Interest, or VOI.) The output of this filter is a structured grid 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 plane from a grid for contouring, subsampling large grids to reduce data size, or extracting regions of a grid with interesting data.
