Hi Tuomas,
Actually, I've read the same README and come up with four different
camera configurations. I haven't tested them though, because I'm still
missing the pre-distortion piece of the puzzle. By bouncing the image
off a curved mirror, the image will be distorted as it appears on the
screen. So you need to pre-distort the image and then bounce it off the
mirror so the two distortions cancel each other out, and the image looks
correct.
There's a couple of ways I think I can do this. One way is by using the
osgDistortion tool
(http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/examples/osgdistortion/osgdistortion.cpp).
It looks similar to the code libraries Paul Bourke wrote, but I don't
know how to integrate that into FlightGear. The second way is by using a
program called Projection Designer with one of the camera groups I've
created (http://orihalcon.jp/projdesigner/). But again, I'm not sure how
to make FlightGear use the program.

Hi.
Two things: First, keep us posted of your progress:) I am also working on
simulator stuff at our aviation club, so this kind of stuff is interesting to
follow.
Another thing that comes to my mind is a spherical door projection example I
remember seeing on README.multiscreen (or it was one other file in the docs/
dir in flightgear sources) - Did you check that example out, did it not do what
you needed? Unfortunately I am also just looking into all this, so I cannot be
of more help, but I remember trying that one, and it warped the display to a
circle and the perspective was all curved, so maybe it could be something
useful?
Anyway, thanks for posting the link, that kind of setup looks very interesting,
given it uses just one projector. Might work for us also..
