Martin,

The most I have seen is four screens on one (Windows) PC powered by two SLI
graphic cards, where each card has two video outputs. To go beyond this is
possible with a linux os using remote displays (DISPLAY 0:0 etc) but you
don't get something for nothing. The network traffic is high and the
resulting graphics are slower as the network reaches saturation even using a
UDP connection. I have no idea what sort of workload it places on your host
(or master) compputer if it does all the graphics processing and pushes
commands on to your network, but I would suggest again that this is not the
way to go. If it was, all the various IG protocols such as CIGI (see
previous posting on this thread) would never have been invented.

So you have reached that crucial decision point - limit yourself to 4
displays assuming it all works or write a CIGI (for instance) interface for
each node type (host and IG) and attach as many displays as you like.

Subject: Re: [osg-users] Help: Using OSG To Build Tiled Display Wall


Hi,

I am currently thinking about how to do a multi-display simulation with OSG
that uses a single machine to feed all displays. The app I am currently
working on requires multiple views, but is difficult to distribute across
machines because of some randomness components in my graphics stuff.

My simulation requires at least four projectors (or eight if necessary and
possible). I am thinking about using a Nvidia Quadro Plex system
http://www.nvidia.de/page/quadroplex.html.

Has anyone here used heavy-duty graphics hardware to feed four or more views
from one machine? What hardware setup do you use, and are you able to render
reasonably complex scenes? Or can you point me in a good direction for more
info?

Looking forward to your responses -
