The combination of motion, audio, incredibly fast visuals (120Hz), and peripheral motion made for an experience you just can't describe.

Some videos to give an idea, but the experience is something else ...........

It was a room just outside the enterance door to the main event room. People saw the setup first when they arrived. When the keynote had intermissions they would open to door to that entry area and they would crowd into the room. It worked quite well.  Even sometime when the keynote was occuring we'd turn off the sound and people were using it.

Here are a few random items I took home from the event:

Hey Alex, do you mind if i ask the width and height of the diy screen in the picture you guys setup. was just curious on the dimensions w/h wise thanks if you don't mind.

56" screen height with 19-20" of blackout velvet on top and bottom. 15 foot wide. Roughly 150 degree FOV -- It's not a full 180 degree half-circle. The GT720 projectors are mounted at roughly 8-8.5 foot back.

I built the screen, so if you have any questions feel free to ask me. smiley

hi,

we make rear projection glass screen and other products,  you can see on www.panvisual.com .

I am highly impressed with your setup and results of virtual-GT videos. I can prepare 3mr x 2mtr single piece  150degree curved rear projection glass screen, Can you help me what graphics card, and camera was used for your three projectors setup.  i am planing to use three sanyo PDG-DWL-100 with lens thro ratio of .5 as i have very limited space behind the screen.

I want to understand how easy it is to do edge blending and geometrical corrections using short thro projectors using ethsium pro as we were planing to use "easyblend"  from scalable display for the same.

if we plan to duplicate the same setup to offer Virtual-GT  experience to Indian People in our demonstration room,. at Mumbai, can you send  your guidance on technical and finacial aspects.

hey brad, thanks for the reply. I ran into a large snag on my new screen build too..material limitation. trying to figure something out. hmm.

Hi Brad, do you have detail photos of the structural of screen? It looks easy to joint and undo isnt it? ,how do you hang the screen. I'm thinking to make other screen moveable or easy to undo at our studio.

Thanks.

hey din, it looks like that material is connected via like pockets that slideup and down the pole? just a guess am i wrong? lol?

looks like pockets sewed at bottom etc too. shrug. could be wrong. maybe is black out cloth too. shrug just my guesses.

On this particular screen the shell is made of 1-3/8" fence pipe segments from Home Depot. It was cut and then bent to size. The uniform bends were rolled with a Harbor Freight tubing roller. The connections use (believe it or not) Schedule 40 1" PVC joints and hose clamps. The screen and velvet materials were affixed to the shell with industrial velcro. The screen attachment point was on a run of square plastic trim that offset it from the shell enough to give clearance for the screen with a uniforn uninterrupted surface without interferance from the shell. The design is not pretty but noone knew the difference. Time constraints pushed a lot of exotic build ideas out of the picture and were replaced with more practical means. I would not suggest anyone use industrial velcro to affix a screen like that btw. Working out ripples in it is a major PITA.

 Frankly, the shell design is very portible and reasonably easy to build and take down. I did not like the way the screen was affixed to it nor the particular screen material we used though. The screen material used would work significantly better for a permanant build that would be affixed to a curved wall surface (like Ivar's build). It was too thick of a material and did not have enough stretch for a free floating screen shell like this was.

I'll look around on my data drive to see if I have any useful pics of the shell. I know I have a few of when it was torn down into pieces for shipping. Maybe that'll be useful.

Thanks a lot and waiting for pics.

I'd edit these pics into the setup but I don't have edit privs for this post...

Screen material arrives from vender.

Velcro comes in several different types at Home Depot. I used industrial but in hindsight the cheaper "sticky back" would have worked just as well.

1-3/8" fence rail pipe in 10.5' segments. About $1/foot.

Hand bending the pipe segments after they were cut to length.

The rolled pipe is checked against a radius template every few rolls to ensure proper radius.

The upright segments are fabricated by cutting to size and fitting the 1" PVC joints.

The first section is fit tested.

Then two sections...

Then four...

Time to quit fabricating for the night and put the car into the garage. The screen is about perfect scale for a real car to be used as a simpit.

The next day of fabrication...design changes are made to better affix the screen to the shell with a uniform uninterrupted run of trim at top and bottom screen affix points.

Screen is intially rough fitted and projectors setup to dial in the measurements and location requirements for the projector mount. 

Screen is broken down into segments for shipping. The pipes and joints could have all been taken apart for more compact shipping, but I wanted a quick build on-site so I shipped it partially put together.

The 270 pound shipping crate is loaded and off to the FedEx loading dock for 2-day shipment from Wichita to L.A.

I'm sure that's a bit more detail than most want, but it should fill in a lot of blanks on the build process for this particular screen. In hind sight it was a learning experience and I wouldn't fabricate many of the things I did with this screen the same way again. While under time constraints it did what was needed though.

Ok that is a great tutorial for someone to do it themselves!  The pipe bender is a bit unique as far as someone having one already, but still, great tutorial.

I do have one question, as it is the issue I keep running into trying to plan a curved screen.  How did you create the flat surface to velcro to?  It looks like a piece of plastic strip mounted along the pipe but i could not tell how you achieved that.

Also just curious, what fabric did you utilize, BOC?

Bloody Brilliant Brad! smiley

Yes, the tubing roller is a bit of a uncommon tool to have. That particular one is around $150 at Harbor Freight. If you ever plan on going with pipe or tubing for a portible screen design this tool is ideal though. Technically there is a difference between a tubing roller and a pipe bender. Pipe benders do tight radius while tubing rollers do shallow uniform curves.

The flat uniform surface was achieved by screwing plastic square trim to the frame. It is available at Home depot in 12 foot lengths. The sticky back velcro was applied along the trim and the other side to the back edge of the pvc/fiberglass screen material. To make it so I could tare down the frame for shipment the trim was segmented near the joint areas.

The screen material was 72" 4-ply PVC/fiberglass screen material from ebay cut down to 60" (source didn't have their 63" width in stock). Roughly $10/linear foot. I would only recommend this material for permanant wall installations.

Again, I do not suggest using that particular screen material with a free floating frame as it's get ripples in it. Also affixing the screen to the frame using velcro is not ideal because it compounds the ripple issue if the velcro is a continuous run. My suggestion would be to use material that has more stretch to it at the very least. That way regardless of what method you use to affix the screen it will be more forgiving about ripples.

In hindsight I'm actually a bit frustrated with the build quality. I did learn both a lot about what would and won't work with fabricating with those materials though. I guess sometimes I just need to lighten a bit up and not be so perfectionist. It did do what it was designed to do. So in that context it was a good success. smiley

Thank Brad. Very detail for me.

This setup is being used again for CES 2011. The screen material has also changed on the build to a flexible fabric material. Expect more updates on this after January 5th. wink

Brad, do you have some tips for projector alignment and setup. i saw that first you setup the projector in the table top position first before you change it into ceiling-mount. Is there any tricks to test using table top setup and final setup using ceiling-mount. what kind of mounting kit that you use. Thanks

That will only work if your screen is built symmetrical with the same amount of space above and below the projection area. It's a quick way of just finding your general projector layout and lens throw distances. Once you have that figured out it'll work the same turned over and mounted in the same location on the ceiling. It's not really something I really put too much thought into. It's just something I did that one time to expadite the projector testing. I suppose it's handy to know it's possible though.

Can this be used with standard monitors for bezel management and angle correction
This would be great for iRacing to not have to use render 3 screens witch is a FPS killer

Is there any reason why you would not use native NVIDIA Surround or AMD EyeFinity bezel management? Angle correction could be altered a bit with the NTHUSIM configuration grid but is primarily an issue of game client camera code. Once a client camera goes beyond approximately 120 degrees the math used in game camera code to render ultra-wide aspect ratios is problematic on the outer edges.

If I use ati bezel management I can't compensate for the monitor angle so the image still looks wrong
If they would implament some angle compensation it would be great so for now we have to use the iRacing
Bezel management witch is a FPS killer I was just looking for an alternative way to do it

How many projectors are you using in this setup
