[Paraview] More Q about Paraview & Tiled Displays

[Moreland, Kenneth]

Try unchecking the checkbox next to client collect.  Be warned that this
will send the reduced geometry to the client no matter what.  Not all
surfaces are susceptible to the decimation, so your client may end up
with a lot of data.

See, that's the trick.. "Reduced" Geometry on the client.  How do I get
this mystical "reduced" geometry on the client,w ith full-rez on the
display?

No matter what I set "Client collect" to, my 60+ million triangle
surface is shown as mere bounding boxes to the client.

No Ken is right.

 

You can get a reduced geometry at your client, but you cannot get an
image (while simultaneously displaying on a tiled display). If you think
about it, it would mean that paraview would have to do two compositing
passes, one for the tiled display and one for the client composite
image.

 

Having the reduced geometry on the client side, seems to work just fine
(that is what you saw here at Sandia :)

Awww comeon, I know that's not true :)  I was at Sandia less than a Year
ago and I saw you guys using it in your new spiffy panoram room.  :)  

So what's the magic trick?

Sorry, but there is no mechanism for creating reduced size image to
deliver to the client when in tile display mode.  ParaView does,
however, send a reduced sized geometry to the client when LOD is
enabled.  You may want to try playing with the "LOD resolution" and
"Client Collect" options to try to get a nice reduced geometry to the
client.

In a followup to yesterday's question, is there any way to have the
image that is displayed on the Tiled-display rendered to the local
client as well?  Right now my local Paraview client shows just bounding
boxes.  The geometry in question is far too big to have the "geometry"
send back (Which it seems there is a "Client Collect" option for), I
really just need framebuffers composited & sent back (Like in the
MPIRenderModule). 

Is there a way to enable such behavior?  I know the resolution would, of
course, be much worse on the single display but it would help alot in
just knowing what's going on.   Also, it seems the options to "Set
Center" doesn't work on the client unless the geometry is shown
(Presumably because the OpenGL query stuff doesn't work if no geomtry is
shown).
