ATTRACTIONS of VIRTUAL REALITY

[Yurab]

Our company developed some "attractions of virtual reality". Now we finished assembling "prototype" the first attraction "Old Zeppelin" (we planning to put it in operation in September).



Equipment:
- computer Core 2 Quad 9650 4GHz, RAM 8GB, RAID 2TB, video nVIDIA Quadro FX 4500 X2 + 4 modules MATROX TripleHead2Go, audio Creative X-Fi Elite Pro;
- 12 projectors BenQ 622c (1024x768, 85Hz in stereo);
- 4 panoramic screens 6x1.5 meter (3 projectors per screen);
- acoustics 7.1 KLIPSCH + receiver Pioneer LX70;
- 12 couches with low-frequence-effects ("Buttkicker");
- 2 IR-transmitters (range 20 meter);
- 50 wireless Shutterglasses.







The stereomovies for attractions we make in 3D-programm (VUE, POSER, MAYA, RealFlow etc.).

[Yurab]

Now future attraction looks like this ("prototype" has size 2x3x2 meter, screens 0.5x2 meter and only one couch, but looks very impressive ):

This settup looks a little complicated and exagerated, but since you are using 'normal' Hardware the price might be not too high in the end...

I mean what are 12 projectors compared to some super highend Cinema projectors at pricing?

I think you should be able to get something about the company name. You are not banned if you say nVidia, too...

[Neil]

Yeah. I'm not too bothered by it. It's if he's trying to sell these VR systems to our members or working hard to promote his site, then I have a problem. I think this is interesting.

What is this system for? Is it an exhibit of some kind?

Can you upload these images to our gallery?

Might be tough to get rid of the heat created by 12 projectors in a small room especially after an extended period of time. Would dual projectors polarised with passive glasses per screen be a better alternative both cost and heat wise despite limited viewing angles. Given the fragility of most shutter glasses and limited battery life span of wireless glasses would it be detremental to the overall longevity and maintenace of this setup?

Also for viewing content im not sure how the end user might know where or which screen they should focus their attention. For example, if my attention as a viewer was required to look behind, would the in content camera pan to show what is behind on the front screen or would there be some form of audio or visual cue to make me look left, right or behind?


Just some thoughts.

[Yurab]

This system is for entertainment, you know . The room presents the "gondola" of "virtual airship", the screens are the "windows". "Passengers" (in this attraction 24 peoples - 2 on one couch) fly (and swim underwater, sail, drive etc. ) by this "airship" from one "virtual reality" to another and look through this "windows" outside. The stereopicture is panoramic (360 grad, total resolution 12288x768), each projector shows (in page-flipping mode) one "piece" (1024x768) of this big picture. And viewers turn his heads "tracking" the action . One variant of attraction has revolving chairs (and +2 screens on the floor) and viewers can to rotate full body :

awesome stuff! when does this come to Ukraine I really wanna test this out

[Freke1]

Looks absolutely amazing

[cybereality]

That has got to be one of the more impressive concepts I've seen. Reminds me a bit of the Star Wars ride they have at Disney World. That wasn't in 3D, but it was a very similar setup in terms of presentation. Some nice concept art there, it looks like you have a good idea of what you are doing. I would very much like to see how the final product turns out.

Also, what were the reasons for going with active shutterglasses? If you have 12 projectors, then doing passive polarized 3D seems like a better solution. Syncing up all those glasses are going to be difficult (as you are probably aware) especially due to line-of-sight issues with a full crowd of people. I'm not saying it can't be done, but its not going to be easy. Then there is the issue of battery life, glasses breaking or malfunctioning, people stealing the glasses, etc. Although you seem to know what you are doing so I assume you have come up with a working solution. Just something to think about.

[Likay]

Woooow!!!! :O

Breathtaking, Would love to see that in real life. Since you already have so many beamers i also would suggest consideration of a polarized rig! The glasses are easier to wear and functions better. The ghostrejection is superb (i have according to measure past in time 85-90% total blocking rate). There'a thread about it somewhere if you can find it. Still love this project! Like fulfilling a dream!

cheers

[yuriythebest]

btw just for the fun of it can you submit stereoscopic (side by side) versions of your 3d concept renders?

[LukePC1]

Passive system has still some ghosting, but I think DLP+ SG can be even better for less ghosting.

IR emitters shouldn't be that much of a problem, if positioned high and at many locations.

For 20 people (one room) you'd need glasses worth of about 1000 to 2000$, which seems to be much less than 12 extra projectors and silver-screens.
I think also the arangement of 24 projectors for a single room might be a little more difficult - but should be possible...

[android78]

Looks like a great idea. My only problem with it is keeping your eyes at the same level relative to the multiple screens. For example, if you are facing towards the front then look to the right, one eye will be above the other relative to the floor screens. This means the images won't line up and will cause inexperienced viewers discomfort (not all will be aware of the technical side of not tilting your head when looking at a S3D monitor either).
Besides that, I just want one of those double width screens in my lounge room!

well their last concept shows rotatable seats, which should fix this problem. Would be super awesome for something like a dragon to reach in!

[Yurab]

The conception of "attractions of virtual reality" is like this: stereoscopic projectors (and 3D Ready TV and plasma) make "virtual interior" in "natural" size (cosmostation, tomb of pharaon, labirinth, haunted castle etc.) and viewers in WIRELESS shutterglasses (i use ONLY SG!) walk (or "move" ?) in this "virtual space" in quite REAL manner - moving his legs . In accordance with this idea developed attraction "VIRTUAL BALAGAN" (7 rooms total 140 sq. meters, 16 screens on walls, ceiling and floor, 46 projectors (and 4 plasma) etc.):

!!!!!!!!!!!!!!!!

[android78]

Hi Yurab. What happened to the post with the videos you uploaded? I started downloading one last night and it stopped at 99%.
Oh well... Nice work anyway. Just wondering if you're likely to setup one of these in Australia... I'd be interrested to go if you were.

Edit: Never mind about the other post, I found your website from your profile, not that I can read it.

[Yurab]

My site is permanently "under construction", i suppose to make english part later (unfortunately my english is not very good: i have not the practice since 1997 when i worked as designer in Indonesia, not far from Australia by the way ). I developed "the line" the attractions from simple like this (6x4x3 meter, screen 6x1.5 meter, "only" 3 projectors, inexpensive computer and acoustics, standing "seats")



to "multiroom" (polyscreen) like "Virtual Balagan".

In "attractions" it's more importantly not "hardware" but stereoscopic "movies'. I make the "movies' in 3D-programms like VUE, POSER, MAYA, RealFlow etc., music - FL Studio, miltichannel sound - Adobe Audition, "assembling" and postproduction - Adobe After Effects. In forum "Do It Yourself!" i try to start the topic with little "tutorials" how to make "stereomovies" in 3D-programms.

[chrisdfw]

Very interesting concept.

Having an image on the floor or ceiling would not work because the left and right eyes need to look at the image "right side up" and with the head tilted at the correct angle or you lose the 3d effect. A person standing above the image lookeing down would only see 3d if they had their eyes at the correct angle which wouldn't be likely.

It would be interesting to have a non 3d image on the floor to show gravel or a road moving underneath at a fixed depth at floor level.

[yuriythebest]

he has a point. unless of course some super fancy head tracking is made that will rotate a robotic arm thingy holding the projector depending on the head position. even then it'll only work for one person and require a NASA budget. Only solution is to keep the people in 1 place, but that would undermine the entire point.

Yurab- I have already watched the videos of the submarine thing flying around in diff environments a while back (also the dinosaur fish thing)- good stuff, but more variety and 'action' would be welcome. Also I assume for the setup you'll render the views for each projector separately right? If the views in the attraction will actually be coming out of the submarine thing (so you don't see the actual submarine) so it's like there are many windows in different directions that would be most exciting.

[Yurab]

It's another attraction - "Flying Saucer" (stereocyclorama): 12 screens are placing along the circle seamless and viewers will standing in center this circle looking in all directions.

The screens on the floor and ceiling i am using in attraction like "Canyon": narrow corridor (2-2.5 meter wide and 8-10 meter long) allows to look only in one direction. In other cases i show on floor non-stereoscopic pictures.

"More action"... Hm... For 5 years i try to make stereoscopic "serial" MATRAX[ref#cked] - the parody on all (or many) blockbusters. Maybe now i start this work "practically"...




MATRAX SlieShow

[Okta]

The viewing areas seem small and why not use rear projection?

wow can't wait to watch this! Btw if you want a few 3d models done here and there I'd be happy to help out I also do voice acting if you require a heavy russian/ukrainian accent

[chrisjarram]

I have a triple-projector rig similar to this with low frequency tactle trasducers (BK LFE) and high-freqency motion (Frex based) - I also have my own ridefilm software which synchronizes to stereoscopic player, the problem is I've not got the bloody space to set up all 3 projectors! Incidentally Yurab, can you tell us which stereo playback software you are using? I had some problems playing back higher resolution stuff on stereoscopic player (not speed, rather it just wouldnt display at all).

[chrisjarram]

The viewing areas seem small and why not use rear projection?

Erm, would that not make the viewing area even smaller!

[Yurab]

Unfortunately StereoscopicPlayer plays stereomovies with max resolution 2048x2048 (per eye), DepthQ Media Server plays stereomovies with max res. 4096x4096, but costs too much (about $6000). Now i am using SP and for playing i reduce resolution of movies from 3072x768 to 2048x512. And i try to make own stereoplayer (earlier i was a programmer ), but this work advances very slow .

[Yurab]

From the outside attraction "Old Zeppelin" will look like this (but without grass of course ):




Without covers (and left screen):

[Hornet]

Yurab,
have You not problems with L/R color differences of Benq s with use of shutterglasses? Have 2 Benq with Matrox DualH.
Randomly when I swithc the system on projectors are "desynchronised -little color diff." It is possible repair this with "auto" reswitching of PJ. Only with 12 PJ ....

[yuriythebest]

hmm, I think if you include the grass you will get more customers. Plus you'll be able to save costs since then you could just put in just regular 2d screens and people will be like "whoa! have you seen those pixies fly out of the screen? " person 2 : "no, I thought they were dinosaurs" person 1: "wicked!"

[cybereality]

Wow Yurab, those renders are off the chain! Just when I thought I had seen it all you post something that blows my mind. Nice work.

[Freke1]

FREE YOUR MIND!
what a lovely garden...

[Yurab]

Yes, i have the problem with L/R color difference. I solve it restarting one projector from 3 while L/R colors become identical on one screen (for 4 screens i must restart no more than 4 projectors; it takes about 10 minutes and only one time a day).

[Yurab]

I have the attraction "Fly in the Sky" for discotheques: the screens (1 or more) stand around dancing peoples and you dance not only listen to music but seeing the video (stereoscopic or not). And standing on floor ventilators blow upward and create the feeling of fly (almost as grass ).

[Hornet]

Yes Yurab, the problem is no crucial.. For my no problematic- this is my home setup( in video 2D, normally in 3D with shutterglasses):

[Yurab]

First "production sample" of "attraction of virtual reality" is attraction "Capsula" :



3x4x2.5 meter, 3 screens 1x2.8 meter, 6 projectors (2 for one screen) BenQ MP620c (1024x768, 2000 Lum, 85 Hz in stereo), 3 3-seat couches with Buttkickers (max 9-12 "passengers"), Dolby 5.1 acoustics (Sound Projector Yamaha + Subwoofer), air-conditioner, wireless shutterglasses.

The "passengers" will "travel" by Capsula from one "virtual reality" to another and through the screens like windows they will look on this "reality". The Capsula in stereomovie will looks like this:

[yuriythebest]

looking awesome but please make more diverse 3d environments.

[Yurab]

On the pictures present only "concepts" for "vehicles". "Environments" will look like this:

Hey Yurab!

Sorry for editing out the naked pictures. pretty women - but G-rated forums!

You should upload these images to our own gallery at http://wwew.mtbs3d.com/gallery
