// .NAME vtkExtractSelectedLocations - extract cells within a dataset that
Dave Demarle
committed
// contain the locations listen in the vtkSelection.
// .SECTION Description
// vtkExtractSelectedLocations extracts all cells whose volume contain at least
// one point listed in the LOCATIONS content of the vtkSelection. This filter
// adds a scalar array called vtkOriginalCellIds that says what input cell
Dave Demarle
committed
// produced each output cell. This is an example of a Pedigree ID which helps
// to trace back results.
