I realised that one projector, even full hd, has not enough (horizontal) resolution to produce a good image quality for 180 degrees. So I didn't pursued this idea any further.
Thus I think two projectors is a better option for 180 degrees visualisation. Even if the two projectors are only 720p, they will give you a greater horizontal resolution ( 2x1280 > 1920). The disadvantage of a two projector setup is that you have the blending area of the two projectors right in front of you. I haven't used blending software myself and I don't know how good the results are.
I myself built a 3 projector setup that gave me 210 degrees (after moving to a bigger house, I had the space for this). I thought that would give me a greater immersive experience. Since I wanted to use my home cockpit for different aircrafts I used a touch tft screen in front of me for the instrumentation. The feeling of flying was indeed very good with this 210 degree setup. But the immersion of sitting in an cockpit were not, because I didn't had an enclosed cockpit, only the touch tft screen.
Now I'm back to an one projector setup. It uses rear projection on an 1.4 meter x 0.8 meter screen with a full hd projector. I sit very near to the screen. The distance between my head and the screen is 0.7 meter. That gives me a fov of 90 degrees. I added touch functionality to my projection screen. Together with trackir I can use the virtual cockpits on this big touch screen. Overall I'm quite satisfied with the immersion it gives me.
More details together with some pictures and a video of my current setup you can find in my post at the digital combat simulator forum.

Any updates on your project? I'm wondering how this would work with one short throw projector. Here is a '180' view with one projector setup with the Jetmax

Re: 180 degree fov with one single projector
Hey Omni, which short throw projector did you have your eye on?? I'm trying to find a suitable setup at the moment too. I think 2 will give enough detail to do the job.
Re: 180 degree fov with one single projector
I'm looking at the w1080st.
I'm going to try and mimic the iDome, Cobra Curve screen setup --

Re: 180 degree fov with one single projector
Nice idea, might find that projector will throw a huge image in that setup, but its a nice projector..
What mirror and software will you use? Still plan to use immersive display lite 2?
