Curved screen , hardware and set up advice

Stoner

Hi all I'm looking for some help please to chose a projector and distances from a screen


This is a caloboration room and we'd like to create a curved wall from white sheets, its poorly shown on the drawing

We'd like to mount two projectors in the ceiling to project onto this curved surface, ideally we'd like advice on
the projectors and the
distance from the wall to ceiling mount them
Rough curvature of the wall

Also if anyone knows the best software to blend the two visual outputs into one, or is this completed by pairing the projectors in some way, cabling , linking software etc

We want to use it for showing 3D models from navis works, ie this is not a 3D image, the software we have will take care of that , we just want to belend the two projectors into one as we assume (possibly incorrectly) the one projector will not have a wide enough viewing angle to complete this on its own

It's known as a BIM cave

this is close to it

Thanks to all for your help.

Splitting the image over 2 projectors is 'edge blending'

Generally only found on higher end projectors, and you need a processor to run the system, not a cheap set up by any means. How big an image do you want to end up with, do you want to fill the full 4m? What height do you have, what aspect ratio do you want to end up with, 4m wide in 16:10 would give a 2.5m image height, but you would need a very high room to avoid people blocking the image, an ultra short throw projector might work, but they are not really meant for that size image.

Most manufacturers have throw distance calculators, just Google Panasonic or NEC or Barco and 'throw distance calculator' to get some ideas of how far back / high you have to be to get the image size you want.
