I'm currently building paraview from sources...
I had errors caused by Qt.
"fatal error LNK1112: module machine type 'X86' conflicts with target
machine type 'x64'" in QtGUI4.dll and in QtCore4.dll
My computer runs Windows 7 64 bits. I have downloaded and installed (not
built) Qt4.7.3 Vs2008.
My compiler is VS2010 64 bits edition.
Do you think it is a building error from Qt or from the compiler version?
I have created a subclass of vtkPVClipDataSet as you adviced me.
If I am right, Data clipping using a box is performed by moving a
BoxWidget, getting the vtkPlanes and providing them to vtkPVClipDataSet
as implicitFunction. Can you confirm me?
If yes, it is not exactly what I was looking for since I need to access
to the box widget to retrieve the polydata. In vtkPVClipDataSet i on ly
have acces to the implicit function, thus the vtkPlanes.
I guess that I need to access to the point in the code where we get the
BoxWidget just before passing the vtkPlanes to the clipper.
Can you show me where it is (sorry, it is the first time i open the
paraview source code, I need help!) ?

Once you make the VTK filter have two output ports, paraview will
automatically detect it and you will be able to see both output ports
in the pipeline browser.

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.
