[Paraview] More Q about Paraview & Tiled Displays

[Wylie, Brian]

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).
