vtkExtractSelectedIds
Section: Visualization Toolkit Graphics Classes
Usage
vtkExtractSelectedIds extracts a set of cells and points from within a
vtkDataSet. The set of ids to extract are listed within a vtkSelection.
This filter adds a scalar array called vtkOriginalCellIds that says what
input cell produced each output cell. This is an example of a Pedigree ID
which helps to trace back results. Depending on whether the selection has
GLOBALIDS, VALUES or INDICES, the selection will use the contents of the
array named in the GLOBALIDS DataSetAttribute, and arbitrary array, or the
position (tuple id or number) within the cell or point array.
To create an instance of class vtkExtractSelectedIds, simply
invoke its constructor as follows
obj = vtkExtractSelectedIds
