Visuals part 3 (end....for now)

Well I've gotten about as far as I can with wrinkly paper and a version of Warpalizer that doesn't save its configuration. I purchased it today but it requires a "dongle" (something that plugs into an otherwise usable USB port) that verifies the software as being legit and not some knock off. It's being shipped from Norway so it will be a week or so before I can get Warpalizer up and running properly.

"What is Warpalizer?", I hear you say. It's software that bends (or warps) the projected image on a curved screen so that to the observer, everything is the same focal point and is distortion free. Without it your 3 projector set up looks funky as all get up. Now the challenge with the evaluation version is that it doesn't allow you to save your settings and sometimes a change in focus in windows (ie. you switch to FSX) will cause the settings you made to disappear. This photo gives you an idea of how Warpalizer works:
You use the edit function to make all of the rows appear to be equally spaced and in proportion to each other. I could only get this in so so shape since the butcher paper screen sags and bunches up unevenly across the projection field. Sometimes I was staring at the image not sure if it was the paper or the warping factor that was out of whack (it was almost always the paper). You can also set the edge blending, where the 2 project beams intersect (on box 11 and 22).

Per my opening sentence of this post, I've tested about as much as I can with this prototype rig. Plus the wife wants to park the car in the garage so tonight I pulled it all down.

Just for giggles, I took the semi circle base of the frame into the sim room to see if it would fit. Oh my it's tight! It works though. I can't wait to re-arrange the room, get the projectors mounted on the ceiling and install some kind of screen. Plywood or a screen hanging down from the ceiling? Will need to think about this one.

What else? Happy to report with all projectors running at 1280 x 800, FSX was managing 30 frames per second while on the ground in SFO. Haven't tried it on an "add on scenery" airport but so far, performance doesn't look like an issue.

  1. All look flyworthy (is that a word)...

    The psychedelic colours give me a headache though :)

    Unfortunately, I don't have the floorspace for such an apparatus, unless I move to the dog kennel. Therefore, my visuals will most-likely be more traditional.

    Thanks for sharing the process as it makes interesting reading and adds flair to ideas.

    Best, Iain
