Hi all. I'm at the very early stages of planning a single seat simpit, and have been pondering the issue of how to improve "out the window" display whilst retaining the obvious advantage of having a replica cockpit to touch (i.e. I'm not convinced by the OR line of thought). Having never been a Track-IR user, I've taken a look at a few videos on YouTube and frankly really don't get it. You turn your head but keep your eyes pointing forward? Huh? This is not something I've ever done in a real world Cessna. Equally there is much discussion on these forums about multi monitor setups and much chest beating about the processing capacity needed to draw a large FOV. I got to thinking that there is a bit of a Schrödinger's cat thing going on here. If you (the pilot) are not looking directly at a part of the OTW, does it need to be drawn in such resolution, or even in colour? I can't see much above 180 degrees and the last 45 or so either side are apparently B&W (though every time I turn to confirm this they are magically coloured in!!!) It struck me that the theoretical ideal might be to combine head tracking with moving an OTW projector such that it displays its high res image in the direction you are actually looking. It seems logical to assume that TrackIR-type technology configured without angular scaling could provide the necessary control input: A kind of 'external helmet mounted display', if you will. The (first) teensy issue that I anticipate is how to keep the image in focus. Either the projector would need to be gimballed at the centre of a highly accurate spherical screen (which incidentally just happens to also be the point at which you'd want your eyes to be too) or there'd need to be some very fancy dynamic control of focus. Is this idea barking mad , barking up a wrong tree :Shame On You: or "OMG, why-haven't-you-patented-it!" brilliant? :Big Grin: Z

These two 737s are the same. Notice how in the picture on the right, the rear of the plane looks equal in size to the front, even though it is actually further away. This is how aircraft and other objects are shown in FSX. The picture on the left is how things look to the human eye - when things are further away, they appear smaller. Is there a way that I can change the view in FSX to be like the left? Thanks, Leif

I'm currently running FlightGear 3.0.0 and using it to run 8 slave computers that use individual projectors to project their image onto a large wrap-around display. I'm using simple batch files to start up FlightGear on each slave. I think I have done all the correct steps and everything seems to be working well except for the fact that the field of view for each image that I have set a specific value for has been ignored and has defaulted to 55 degrees (causing overlapping between all the edges). It seems that when "--fdm=external" (or "--fdm=null") is inputed the "--fov=xx.x" is ignored because I tested it excluding "--fdm=external" and the images were all perfectly calibrated but when you try to fly, each slave goes haywire because "--fdm=external" has to be on. The slaves require different --fov values since the projectors are various distances away from the screen. Any suggestions on what I can do to fix this problem? Thanks. Below is an example batch file of one of the slaves: C:/Program Files/FlightGear/bin/Win64/fgfs.exe ^ --fg-root=C:/Program Files/FlightGear/data ^ --fg-scenery=C:/Program Files/FlightGear/data/Scenery;C:/Program Files/FlightGear/scenery;C:/Program Files/FlightGear/terrasync ^ --aircraft=f-14b ^ --control=joystick ^ --disable-random-objects ^ --prop:/sim/rendering/random-vegetation=false ^ --disable-panel ^ --disable-sound ^ --disable-hud-3d ^ --disable-ai-models ^ --disable-ai-traffic ^ --disable-real-weather-fetch ^ --enable-fullscreen ^ --geometry=1920x1080 ^ --bpp=32 ^ --disable-terrasync ^ --disable-fgcom ^ --fdm=external ^ --native-fdm=socket,in,60,,5511,udp ^ --native-ctrls=socket,in,60,,5512,udp ^ --fov=50.2 ^ --prop:/sim/view/config/heading-offset-deg=65.4 ^ --prop:/sim/view/config/pitch-offset-deg=11.1
