there are some major problem with this.
First off to overlap the images of two projectors exactly is a hard process.
Secondly there are not big enough gaps between the projectors pixels to interleave another projectors pixels, unless you had the projector very very far from the screen which will make your overall size very large.
Also the more compact the image from each projector the more compact the light is, making it appear brighter.
Also I can't even begin to think of what a pain it would be to write the code for a while of your idea.
you are defnitely posing a good question for other options that may be out there.
Although i think the way that things are going now is relatively the best.
yeah, have fun paying out the rear for it as well.
also this is an article from 2002, where are these projecotrs now????
exactly, it is not perfected yet.
it costs too much.
I know a prof who has a full res HD projector but it cost over 20K
eventually this will work, but eventually you will have full res HD DLP chips as well, but guess what, when that happens people will still tile them.
The wall i built was 24 XGA projectors doubled up to 12 tiles. And no one would do that for brightness, it gives you stereoscopy.
And that was done for a mere 3K per projector.
not to mention the fact that the more projectors you use the closer they can be to the screen and the smaller the footprint of the whole wall can be.
you obviously are not very informed in the industry.
yes tiled displays have been going on for some time, but NO ONE has a good seamless integrated solution.
the only solutions that you might be able to easily set up are cubes and they have obvious seems.
Plus Barco projectors that can do this on their own cost 20-30 thousand a piece. and they still require a professional to set everything up and write software for the computers to run together.
On top of that try getting all of the computers to sync their frame rates so you do not get any tearing between the screens.
Try playing a pre-rendered movie across 10 computers flawlessly in sync
The biggest problem is the only people out there intersted in the stuff are universities with grant money:)
yes it is much bigger, but it is a monoscopic display.
these displays are very impressive, but they are not stereoscopic
I have seen theirs plus their 6 sided cave (insanely cool). This is stereoscopic and is the closest thing to the lawnmower man.
did you see the 12 tile projection system after is was finished in the center? that is the one i worked on. Yet essentially it is a cluster and 24 projectors, but it is quite a feat to design a system to align them all.
if you have any more questions e-mail me bartek@purdue.edu
This setup is cool, however a less covered display is Purdue's 24 projector stereoscopic tiled display wall that i spent a year designing and building through the Envision Center at Purdue.
This was built from 24 projectors in 12 tiles, with a custom designed and built frame. There was no software used to align the projectors, just me and an alignment system aligning everything by hand.
There are a lot of universities and centers building tiled displays, it is much harder to try and build one in stereo(two projectors per tile, one projector for each eye. This is coupled with polarizations filters and glasses so that the right eye only gets the 12 right eye projectors, and the left eye gets the 12 let eye projectors. The stereoscopic settings are controlled with the software and the quad buffer stereo built into nvidia graphics cards.)

the screen is probably flexible and rolls up. you can usually get any screen material flexible or rigid or semi rigid (rigid sections)
one crappy projector in you garage is not the same as tiling computers and displays.
