Regarding hiding cells/nodes, in vtkStructuredGrid there is "BlankCell"
and "UnBlankCell", "BlankPoint" and "UnBlankPoint". I don't know if you
can access that functionality from within ParaView given a selection,
and I don't see "blanking" in vtkUnstructuredGrid.

Hi,
I'm programming a plugin for ParaView, whose purpose is to be a
pre-processor for a finite element simulator. It is all based in
selecting nodes or elements, and defining some regions - based on these
- so that one can attribute boundary conditions to them. The main
challenge seems to assure that the user will be able to select EVERY
node or element he wants. So I'm treating all kind of selections, but
I'm stucked in some problems and I have some questions:
1-Why the "New Range" button in the Selection Inspector is always
deactivated ? Is this option already implemented in ParaView ?
2-It would be pretty useful if the user could select all the
nodes/cells in an coordinates interval. Is there anyway to do this ?
Selection based on location only allows me to select one coordinate at
a time, but I can't specify an interval.
3-Is there anyway to "hide" selected cells/nodes ? I don't want to
extract them with a filter (I would do this by just applying the
Extract Selection filter) but just restrict the mesh in the screen to
some subset. If I could do this, it would be easier (or even possible)
to select some cells by picking.
4-Finally, Is there anyway to control Frustum's shape or dimensions ?
Thanks in advance for your help.
Regards,
Rafael March.
