Hi Folks,
I'm developing what I'd think would be a fairly common application for this
group: A CAVE setup with multiple PCs on multiple
monitors/projectors, head tracking, arbitrary screen resolutions per monitor.
Most of that is easy, the head tracking is the problem.
Does information exist in more-or-less one place for such a configuration?
I've found information on ProjectionCameraDecorator, and
on clustered rendering, but the cluster example uses the MultiDisplayWindow,
which isn't suitable for breaking out the separate
viewports needed for a CAVE environment. Am I missing something obvious?
Should I be looking straight at a ClusterWindow?
Also, with the architecture above, is it possible to push the
screen/viewport/window information out to the servers, so that only
one instance of a configuration file is necessary?
Marcus commented on most of that, in OpenSG the master controls
everything, so the salves don't need any configuration, they just need
to know their name.
We really should have a simple example for this. I would like to write
one, but I'm too far away from my system to do development right now.
Am I better off spending more time with VRJuggler and going that route for such
an application? I'd rather not, since it seems that
with each new software package I inherit an enormous amount of overhead in the
form of 3rd-party packages, version dependencies,
compiler issues, etc.
Juggler has some overhead in terms of dependencies, but they have some
pretty detailed instructions on how to set up and build it.
The only thing that you REALLY need from Juggler for running a Cave with
OpenSG is the head tracking though, which might be a bit od overkill.
I know other people have built and run caves with OpenSG without
Juggler. Could they comment on what they're using for head-tracking?
Thanks
Dirk
