    I would like to try to make a curved screen to use with a single projector (Optoma hd142x or benq W1070). So I have 2 questions before starting my project:

    1) I know that probably will be necessary to be used in software for warping, and I also know that with a 180 ° curvature it is absolutely necessary to use 3 projectors. Do you think that with a single projector and a software of warping I can project on a screen of 120 ° or I have to stop at lower values like 90/100 °?

    2) i had read some good reviews on nthusim but entering their site I read that the software is no longer available. Also I can not register to request a copy of this software. Do you know where and how I could find it? Alternatively there are other cheap and equally valid software?

    Thanks for support

    fly elise is a software like nthusim?
    regarding the angle of the screen?

    Yes they make a blending / wraping software - you can use a demo for 1 month with water marks. I used it while experimenting with my 2 projector / curved screen:



    Now i have to say calibration was a pain in the a$$, it takes time to get the geometry just right. And software can play tricks on you but once set you just save a profile and you are good to go

    These are cheapest crap projectors i could get as the whole idea was just a test.

    Resolution 1024x720
    Lumens - no idea

    Price wise - building this costed me about 300 bucks including projectors but i did not buy the software (just used demo version for some time)

    This setup was very good due to scale of the objects (could really get sim racing 1:1), but not using it anymore due to space constrains in new place

    The trick is to measure properly what the projected image size will be and then making a screen for that exact size to use as much pixels as you can.

    Also in my example the Angle between the projection and the projectors was to high thus i had a lot of geometry setup to do (not the 'demo' sign curvature)
