project. We would have to start using a different OSG class,
CompositeViewer, to support multiple views from independent view points. Our
terrain pager would need a complete overhaul to use the PagedLOD scheme of
OSG, and the Flightgear view manager would need to be aware multiple active
views.

osgViewer to provide a "video wall" style of multiple displays that was
demonstrated at LinuxTag for 2 years, (I think!). I later generalized this
to support general monitor arrangements (like a panoramic arc) and general
combinations of screens and graphics cards. I don't know if the LinuxTag
demo team uses the original video wall feature (still supported) or the
"new" stuff.

Sorry Mathias if I mis-attributed that effort.  I know you did most of the
original OSG port!

  except from the multi-screen system which formerly had been
introduced by Mathias Froehlich and which has done a great job, at
least for not too complex display setups  ;-)

Hi Kavya,

I think you have just summarized all the limitations of the FlightGear
multi-camera/view/display system.  Tim Moore is the person who developed
this feature (nothing existed before his efforts) and maybe he can offer
more insight.  I know that in the case of menus, hud, 2d instrument panels,
there would need to be some significant code restructuring to allow these to
be displayed on other windows.

One possible way to work around some of these issues would be to leverage
multiple machines talking to each other via network packets ... that may or
may not be an option in your situation, but I thought I'd mention it in case
you hadn't previously considered it.

Regards,

Curt.
