The three Optoma GT1080 Darbee projectors and the ceiling mounts have arrived! It’ll be some time before they go up, still waiting for UPS to find my lost Sim PC parts. Once the sim pc is built I can move forward with the project!
Knowing the size of the base of the sim (8′ x 8′) I was able to do some math and figure out the size of the screen needed. There is a 7″ space behind the end of the rear windows, so the numbers come out to a circle that has a 128″ diameter for a 270 degree view using 3 projectors that are 90 degrees each. This tells me it’s a 64″ radius and that is key. Knowing that will allow me to use the ol’ nail, string and pencil to make a compass trick and draw out the curvature of the screen onto plywood, then add 4″ and draw the other line. I’ll cut out several of those to form the base of the circle and attach them together. I’ll use 2×4’s as the uprights and then cut the came pieces out for the top. Finally I’ll use 1/4″ or so mdf type material to make the screen. It gets painted satin white usually, which I may do regardless. But my intention is to get projector material/fabric and cover the entire inside surface with it, so that there are no lines from the construction.
After doing lots of research, I found that many sim site projector discussions or reviews were many years old, in fact, dating after I built both the Cessna and original 737 sim at my old place from 2012ish! A review or two from 2017 but nothing past that. At any rate, after going over various posts, I went with three Optoma GT1080 Darbee Short Throw projectors! They are 3000 lumens, have a .50 throw and a low input lag of 16ms.
As far as warping software goes, I went decided to use the Ultimate version of Immersive Display Pro by Fly Elise-Ng as it has direct features for warping multiple projector images and exporting it right to the flight simulator software!
