[Paraview] Mesh edition / modification with paraview

[David E DeMarle]

Yes.

ParaView stores data in vtkDataSets, and each filter in ParaView takes
in one or more vtkDataSets, looks at them, and produces one or more
vtkDataSets (often by shallow copying the inputs).

If you understand the vtkDataSet and vtkAlgorithm API's well enough,
the operations you describe are fairly easy to accomplish. (See the
python programmable filter wiki page for examples).

However, providing a good UI that lets the user control which parts of
the DataSet geometry and topology are modified is not altogether
trivial. That would probably require significant use of vtkWidgets to
create the visual editing tools, ParaView's Proxy/Property pattern to
map the tools behavior over to the server side filter properties, and
how ParaView's QT ObjectPanel interfaces exposes properties in the
client application.
