Hi Utkarsh,
Thanks for your reply!
I'm used to subclass ITK and VTK classes, but I install Paraview using
the binaries.... not yet from the sources.
If I understand you, this could be very easily done subclassing the
PVClipDataSet. What about displaying or saving the second output?
How can I get both output ports?
Thanks again,
Laurent.

What I'd do is subclass vtkPVClipDataset (the filter paraview uses for
Clip). Make the subclass a two output-port filter (by calling
vtkAlgorithm::SetNumberOfOutputPorts(2)) and producing the polydata
matching the implicit function specified as the clipping function on
the second output port. Now you can save/visualization both the
clipped dataset as well as the clipping box. Are you familiar with
writing vtkAlgorithm subclasses?

Dear Users,
I usually clip meshes using the clip filter and a box, or a plane. I would
be interested in exporting the clipping box data, not the clippedData, but
the box itself. I also would like to get the thickness of the box, eg.
distance between two handles.
I know that VTK allows to do that (using the method GetPolyData), and that
it doesn't work properly (you have to triangulate the data first). There is
no option in paraview to retrieve the box.
My solution is to create a filter that do the same job as the clipper with
the additional ability to export the data and compute the distance. But I'm
not sure to be able to handle a widget inside my plugin.
Since I've never wrote a plugin for paraview, I prefer ask before!
So, is it possible?
Is there another (simpler) way around? Add a check box to the "properties"
of the clipper to GetPolyData ?
Thx,
Laurent.
