Hi Bob,
My goal here is to create .cfg files that describe orientation of the
display surfaces. I suppose env variables would work for simple cases,
but I need to be able to put my displays into a non planar config -
orthogonal surfaces.
Hmmm, that would be interesting for us too, but in a different
project... We have a simulator which uses 4 screens (left, right, front,
top) all oriented toward the user, but not necessarily at 90 degree
angles or centered, and it also has a head tracker. This setup requires
asymmetric view frustums which are specified using physical measurements
(viewer position and screen corners), and the current code to do that is
kind of ugly and painful to look at, so if something like what you're
talking about could be used for that, it would be great.
Sounds very similar to our Mechdyne Flying Flex. We tend to use it in
powerwall mode when dealing with the larger groups, but have occasion to
close it up into a cave-like configuration as you've described above. We
are also quite fond of a 'gullwing' configuration with the left and right
walls pulled off of planar by about 2'. This makes for a nice
pseudo-curved screen config.
I hope you'll consider contributing what you come up with for inclusion
into OSG. Interesting stuff.
Anything we build here for OSG-related stuff will most definitely be
turned back to the community with gracious thanks.
