Adds a two more output ports to vtkExtractSelection, the second port contains an id selection and the third is simply the input selection.
vtkPVExtractSelection adds a second port to vtkExtractSelection.
- Output port 0 – is the output from the superclass. It's nothing but the extracted dataset.
- Output port 1 – is a vtkSelection consisting of indices of the cells/points extracted. If vtkSelection used as the input to this filter is of the field type vtkSelection::CELL, then the output vtkSelection has both the cell indicides as well as point indices of the cells/points that were extracted. If input field type is vtkSelection::POINT, then the output vtkSelection only has the indicies of the points that were extracted. This second output is useful for correlating particular cells in the subset with the original data set. This is used, for instance, by Chart representations to show selections.
- Output port 2 – is simply the input vtkSelection. We currently use this for Histogram View/Representation. Since that view cannot show arbitrary ID based selections, it needs to get to the original vtkSelection to determine if the particular selection can be shown in the view at all.
