I hope this isn't too off topic. However, would it be possible to make a curved screen for gaming? I'm thinking of the screen being a 225 degree arc then using 3 projectors hooked up to a triple head to go device for one continuous image. This would greatly enhance the immersion factor. I've seen some comercial applications but they are way over my budget.
That's exactly what I was thinking. By using a PC, Triple Head to go, and 3 projectors. The triple head to go is designed to attach 3 monitors to one graphics card in the PC. The game would also need to support very wide resolutions. A 1900 bit screen x 3 would be 5700 across.
Does the Triple Head video driver allow you to warp the geometry to make things line up between the three images, adjusting for optical distortion? I vaguely remember seeing something in an nVidia driver somewhere in my foggy past.
What games? I have a tripple head setup (just monitors) and I use SoftTH. http://www.kegetys.net/SoftTH/
There's LOTS of options in the setup. It's cheaper than buying a TH2GO box, but game compatibility is limited. They have something called cyclindrical distrotion (which is looks like he removed in the latest beta), not sure if that does what you are looking to do.
Like Mark said you will need a lens or else you will be out of focus I would think. I gotta think someone out there has done a diY version of this. Might want to look at sim racing or sim flying sites.
