Awesome looking setup there Gene. I have been keeping up with this for a long time and a few questions keep coming back. With the background noise in the video I am assuming that is the vacuum to pull the display tight; so when you wear headphones or use the volume in game do they overcome the sound of the vacuum? Also I remember once that you were trying to accomplish this without the vacuum but it appears that you were unable to do so; so would any old vacuum work and have you considered moving the vacuum to any other area away from the computer but still attached via a longer hose to reduce the noise? I know that a vacuum works better the closer to the source it is pulling against but if you move it farther away would that effect the display any?

@The Nephilim - the video should play - it's just a regular YT video. You might try going to http://www.youtube.com/f15sim and see if that helps at all. @Reschke - The vacuum is actually about 18' away and on the other side of a shelving partition. I still have a few things to do to completely silence it. As long as you don't pinch the diameter of the feed line, you won't reduce the vacuum over a long distance. It just takes a bit longer to pull the mirror down because it would have to remove all the air from the feed line before it could start on the mirror plenum volume. Thin film mirrors are really the only way to go with this - the solid form was a blind alley for me. tnx. g.

Wow congrats Gene that is truly amazing! But will it fit around the F-15? LOL!
I've got a bad feeling about this.....

Gene, that is looking very cool! I am very happy for you I have a question about fs rendering or other games for that matter. I know when using triple screens the side monitors stretch the image. This isn't so bad for some stuff as your focus is at the center monitor and because I use trackir when I look to the side and am still mostly looking at the center monitor. With your setup you are not using track ir so I wondered if you had one large eyefinity type display or were you rendering the front and each side separately. On a similar note, the software you use to create a map to remove distortion, can that be used to compress the stretching that happens on games that do not support rendering 3 screens separately? Anyway, looks great!

Any image generated as a single perspective window will have stretching towards the edges. This is an unavoidable consequence of a perspective projection. Another consequence of a single perspective projection is that it is geometrically impossible to reach 180°, and the distortion gets really bad as the FOV gets large.
To get around this limitation, we're using 3 separate windows in FSX. That can be used to eliminate the stretching, but cannot produce more image than is generated, as in a game that uses only a single window won't ever be much good over ~120°, if you're looking for a 'correct' image. With FSX, because we're using three separate windows, we are able to go beyond 180°. I emphasize 'correct', as Need for Speed (a single-window game) looks absolutely incredible, even when it's stretched to 210°. Since you're not paying much direct attention to the sides, it's just peripheral vision and adds tremendously to the immersion. FSX, on the other hand, would feel strange and make pattern-flying difficult if the view directly to the side were showing something that was significantly in front of me.
Keep in mind that we're using a trial license of Sol7 at the moment, which has the capability to apply the screen fitting warp as well as a secondary geometry-correcting warp. There's a good chance we'll go back to NThusim at some point, as Sol7 on 3 channels retails for ~$6000. NThusim is capable of removing the distortion, but is only configured with an alignment routine to fit a rectangular grid to your screen. If you want to correct the distortion further, you need to know what the grid should look like when the image has been corrected, and make it look like that on your screen.

Thanks! You've got a fun job I bet. The dimension was picked out of the air - it just happened to be the right size for the max Mylar size we could get. I had no clue about it until Wayne got involved - I was going to use a different system all together (that would have not worked). g.
