Does anyone know of a DIY 360 ring screen with how to set up the projectors for such an application? Someone help. After contacting some companies it sounds crazy expensive and I think doing it myself would be cheaper. In fact I saw such a setup in Austin Texas at a bar and asked who did the work and they said an employee that use to work there. So I was thinking if a bar person did this why can't I. Help much appreciated .
Never done it. But typically projectors are mounted vertically about even with the very top of the screen image. So depending on the diameter of the circle and the throw ratio (Distance divided by screen width) of your projectors you would need to mount them on ceiling mounts at the appropriate locations. I do recall seeing a couple of setups (Maybe Disney) where the projectors were mounted in the walls around the circle but that would require some pricey gear with really long throw ratios. One issue is that the optics in consumer projectors are engineered for flat screens and if you shine it on a curved screen it will distort the image. I'm sure there are some lenses that could compensate for the amount of curvature.
Setting up the projectors and screen would be relatively easy. Then you need to deal with sourcing and processing the content for a 360 view.
A 360 degree camera system, storage and playback system
Or if you mean the source of the SCREEN, you just put several curved screens adjacent to each other. Or one really long piece of screen fabric and plan for one seam.
Alternatively you could just build a round drywall room and paint the walls with a screen paint.
Looks like they're just using 4 PJs (you can actually see 2 in that picture) projected albeit badly onto a circular screen. I don't see what would be difficult about that unless you actually wanted to avoid the image distortion - clearly the person who set that up didn't care about pincushioning etc.
