Stereo 3D projection for Corporate event
on Jun 23, 2011 at 10:46:33 pm

Hi all,

I'm going to keep this question simple. Has anyone out there successfully produced a live Corporate event (audience around 800 or so) projecting 3d stereo video using polarized projector(s) silver or black screens. I'm talking screen size of 28x16 or larger.
And doing it in a very cost effective way (budget big concern).

I've been researching the DepthQ passive modulator (works with 3D ready projectors) and DaLite black passive rear projection screens but cant seem to find what this will all cost for a 1 week rental, nor if such a screen is readily avaiable and not a custom build.
If I cant get past this part of the puzzle, there's no need to worry about the 3d camcorder and editing software+plugins or 3d delivery method (blu-ray, laptop, media server, etc.)
Thanks in advance

It's very do-able, Ken. A 3D capable projector for that screen size won't be very cost-effective though (to rent or setup). You may be better off with two projectors and linear polarizing filters. That gives you the cheapest glasses, filter system, and lets you use one extra projector to back up both of the others.

Ignore any discussion of circular polarizing being better since 'you can tilt your head'. First, you can't see stereoscopic 3D with a tilted head, second people don't need to rest their heads in corporate shows (mostly ; ) and third, crosstalk and light loss are worse.

You will need a screen that supports polarized projection - not sure about the dalite product.

Thanks Bruce,

Finally getting cost feedback from my AV sepecialist, way too much $$ for large silver screen rental. I also understand the projector stack has to be perpendicular to screen, bringing our front projection flown from ceiling way down too close to audience's heads. Not good. Rear projection would require DaLite black , cannot find rental house for that, seems you have to buy material from DaLite ata max 16' high roll, width is as big as you want , not sure of $$$ and we wouldnt buy this anyway for a one off show.
So, I'm on to other options, I feel I will be delving into 3D stereo on a trade show project in the future using Vizio 60" passive 3d LCD or similar. Much more cost effective and easy setup.

I was recently asked to check into the feasibility of 3D projection for a group of a couple-hundred or so in a relatively intimate setting for a convention here in Vegas.

What I found was that viewing angle was what would hurt us the most, as even if the display is visible, the brain has a heck of a time trying to see 3D from too far from center.

I'm eager to get a consumer-grade 3D display in here soon so I can play with it, but we opted not to use the tech for this particular show.

Looks like you found out the same things. Too bad, as consumers really seem to gravitate towards 3D these days. I wonder which will happen first: large-scale playback getting cheaper or consumer taste shifting away from 3D again.

Best,

Steven

Hi Ken

I can supply a Stewart 18x32 3d rear screen as well as the projection and polarizers to complete the system. This was utilized at an event in NYC and looks great.

Matt,

that sounds real interesting. I did some reserach on gray screens and found they work best for motion video. We usually switch Powerpoint presentations to same screen we open with (In this case, would be a 3D stereo opening video). What I read is any static presentation screens, especially using white backgrounds,w ill look dull and washed out sue to the gray screen material.
Being you have exeperience with this, have you found that to be true?
Or did you just project video on the screen?

Im also reading that the audience cannot be off center or you lose the 3D Effect. That doesn't seem to happen in movie theatre?

The screen we own is a Stewart 150 RP screen that is a neutral grey with a gain of 1.4 and excellent viewing angle. We used it at a Macy's corporate event with non 3D powerpoint and imag as well as passive 3d content. The screen represented all colors with excellent fidelity as long we hit it with enough light. As far as viewing angle of the 3D effect our client was very sensitive to that same issue. The event was in the MSG theater in NYC and we had approximately a 100 degree viewing cone. Although the effect was lessened at the extreme edges of the audience it was difficult to quantify and very subtle. Suffice it so say that the client was very pleased with the performance of our system.

Thanks for the info. I looked on the Stewart web site and saw a mention that a long throw projection is recommended (makes sense).
We have space for long throw in one venue.
I will contact you if management goes in this direction. thanks again for the very helpful info.

Ken

Your welcome, sharing info is what the board is all about.

A long throw lens does help lessen the angle of attack on the screen which helps preserve polarity. Of course we all know how many shows allow us enough room to do long throw RP. The Macy's show was done with .8 lenses. There was a slight dropoff in the 3D effect around the edges of the screen but it wasn't too bad at all. Since the media usually has the important content in the center the overall effect was preserved. I've also used a 2D to 3D convertor that allows input of a single HD/SDI and produces a L/R output. We ran some old powerpoint slides through it and it produced a great 3D effect.

Where are you located? It may be possible to do a proof of concept for your client depending on the geography restrictions.

Let me know if you need more info or would like to proceed.
Matt

Cool. I'm in Boston but our shop is in DC, we also have a demo room there if the client wants to preview content. It's tight with the ceiling height but we should be able to hang the screen there. We own all the necessary polarization filters, projectors and equipment to do it all in digital HD.

Well, thanks for providing this corporate event places with 3d projections as I am also looking for such venue with high tech system and found it over here. I also searches more and found more links.
