display idea

[bic 44]

I am thinking about diyaudio.com do it yourself projection screen. I was thinking of building one box, but with three projections, but the cost would be double. Instead, what if left, front and right views were put on one screen?I figure the image will be stretched anyway, so the left and right should be able to be squeezed on?

Hard to understand ...Could you post a shemaBOB

window 001 is left view - shift 4window 000 is front viewwindow 002 is right view - shift 6http://forums.avsim.net/user_files/80099.jpgOn the screen they would be over 50" wide and stretched out in 1024x768. Furthermore I would curve the screen to create a wrap around effect...

I think what he means is one display unit, three lenses, and black dividers between the left/front/right views. Sort of like below: Left Front Right Lens Lens Lens ______________________ | | /Dividers -> | | / <- Dividers ____|______|____/ | Display | |________________|

Hopefully someone else can elaborate on that, as my ascii art isn't too brilliant!

Yep. I didn't think of using three lenses though. Ideally just one.With all the three views, being displayed and the distance from the projector to the screen, they should be stretched out enough (pixelated?) that I think it will work ok.

Thsis what I want to do with single projector (1280x720) !!! But not sure the feasibility.Alkit

The main problem is the view angle.You have to fine tune the angle, in order to have the borders perfectly overlap.But you can't to this inside the sim, you have to go to the panel.cfg and enter there the angles. Then reload the plane.Painful process but necessary to achive the result.

Whereas you can move the window view with the keyboard, fine tuning it to be exact can only be done via the .cfg file. For example, if the keys pans the view by 45 degrees, and you want 20 degrees, you will need to edit the .cfg file.
