I wonder how they project the "world" on a curved screen? It's hard to
tell how many projectors they've got going, from that pic.

I count three. (?)

I see three projectors. Unless they have very special lenses indeed,
I don't see how they can project clear images onto curved screens.

Setting up the over-lap between the screens so that it doesn't look
weird must be a tricky affair, indeed.

*buy* a curved screen? :-)

The biggest problem should be eliminating "keystoning" so that the overlap
can be eliminated; and more expensive projectors should include that
adjustment. Then the unused area, after having eliminated the overlap,
should just appear as a dark vertical line.

I didn't spend enough time to look at the specifics of the simulator used in
the clip; but the annunced identified it as a Frasca TdruFlite simuator and
the Frasca website: http://www.frasca.com/ with the display options shown

There is fancy stuff you can do with the video feed before sending
it to a standard projector, but I don't know how it is done. I
haven't played with this kind of thing in years, and that was on
high end SGI stuff. We had a machine in the lab that was driving
sixteen displays. That was a fun machine to play a flight sim on.

After you get the curved screen, you'll be looking for the next
upgrade. Why not just skip a few steps and build an IMAX dome
theater at the hotel?

Yanno, take a few of the aircraft parts that get donated to you and
dummy up a real cockpit. Put relays behind the switches, and connect
them to the keyboard (or just take the keyboard apart and run wires).

Instant (heh) upgrade.

You can run movies in them too.

Sorry abbout piggy-backing this on Margy - Jay's post was gone.

You could see where the projector's image ends on the screen and mask and
paint a thin black line on the screen. That would make overlap a non issue,
and be a minimal distraction. That would be the easy way out.

Get some bulk screen material, and sew a flap on the bottom and the top of
the material. Get some thin wall electrical conduit, and bend the
appropriate radius in the tube, with a top and bottom matching tube. You
would want to weld the joints, instead of using a connector. If you weld it
yourself, be sure to not breath the fumes, because the galvanized pipe
welding fumes will give you a very nasty headache, just for starts.

To mount it, make brackets to screw to the tubes, and fasten them on after
the screen has been streached on, so the screen will se the same tension
everywhere.

To make it somewhat portable, use some spreaders from the top to bottom
tube, mounted the same way, but mounted so they will be back away from the
screen. A mounting from the bottom to the floor could have some casters, so
you could roll it out of the way.

I'm not sure, but I think for the best results, a special lens would need to
be used, or a program to get the right aspect ration projected onto the
screen. Even then, I'm not so sure that it would be projected in focus
without a special lens, since the distance from the lens to a flat screen is
different (longer) at the sides of the picture as compared to the center of
the picture. With the curved screen, it would be the same distance on the
edges and the center.

I'll bet it would be more in focus. I don't think lenses are designed
to take the straightness of a screen into account, and we just put up
with blurry edges and a sharper donut.
