Greetings,
I'm new to this forum. I'm currently building a 767 sim and have been waiting until the cockpit is near completion before attempting the visuals. My plan is to build either a curve ( 6 foot radius) or a spherical type as seen in NThusim Test Rig. My apologies if this has already been answered before. Aside from the building difficulty , can someone say if there would there be a noticable difference having the spherical screen over the curved screen.
Thanks,
Mike

Yep, with circular screen you can jump right in quick with the build and do it dirt cheap. My particular screen is two raw canvas drop cloths for $20 each and four pieces for 12 foot long 1x1" plastic trim. Working out the complex curvature of a cylindrical screen isn't an easy project. I'm assuming they're mostly pre-built kits you can get though. I'd not want to do a DIY screen like that unless I was really good with sowing multiple arcs of screen material in a consistant manner.

Please post any findings, I for one would be interested what you find out!

Agreed, don't be afraid of DIY and documenting it here. More options the better when it comes to screen ideas. I'd do some projection material tests before I got too far though. Make sure the material isn't too glossy. If it is, you'll get hot spots in your projection, which will blow out the bright areas. Projection must always be mindful of the dark shadowy areas and the bright areas of the projection and seek a material that balances those to look good.

Sounds very interesting, we're looking forward to the results!
I would recommend making a cylindrical screen, at least at first. Spherical screens are definitely harder to make.
But to answer your question, spherical does have a visual advantage in that it can make it harder for the brain to locate the screen. Due to the second curvature, you can struggle to establish at what distance the screen is.
The visual advantage of a cylindrical screen over a flat screen is a huge. But the advantage of a spherical screen over a cylindrical screen has a much lower reward:pain ratio.
