Subject: Re: [Paraview] Displaying volume outside of mesh as solid
Sergey,
What Cory said is true that ParaView cannot directly render empty spaces.
However, you might be able to get something close enough with the backface
styling rendering controls. These controls let you render surfaces whose
“outside” is facing you different than surfaces whose “inside” is facing you.
They are an advanced property under “Display” in the properties panel. The
easiest way to get to them is to type “backface” in the search box on the
properties panel (as shown in the attached screenshot).
Try changing the “Backface Representation” to “Cull Frontface”. That tells
ParaView to not render any part of the surface where the outside is facing to
you. That should remove the outer surface in the front and instead show the
inner surface that should be facing your hollow volume. The attached screenshot
shows me using this to show a sphere clipped out of the center of a grid. You
will note that you also see the back faces of the larger grids. That is
inevitable. There is no way for ParaView to know the difference between the
faces of your mesh that are on the interior hollow region and those that are on
the external empty space.
(Note, that if “Cull Frontface” does not seem to show anything different, try
“Cull Backface”. That might work if your surfaces are for some reason inward
facing. That shouldn’t be the case, though, when ParaView is rendering the
surface of a volume.)
I hope that helps.

There isn't anything in ParaView to view empty volumes. At some stage, the
volume you are talking about needs to be represented by a grid or mesh for it
to be visualized with ParaView. If you can generate a volumetric mesh outside
of ParaView, then you could use all the visualization techniques in ParaView
that apply to volume meshes. As a post-processing application, ParaView has
essentially no built-in functions for generating volume meshes.
Hope that helps,
Cory

Hello,
I am looking for a way to display a volume that is not covered by mesh
(its located somewhere in the middle of mesh).
By default such volumes (without mesh) are shown as empty area, and
meshed area is shown as solid.
I need to reverse the solid and empty areas, so that non-meshed volume
is shown as solid, and meshed volume as empty.
Mesh is in 3D.
Is there a way to do this?
Thank you very much.
Best,
Sergey
