Polarized stereo 3D using 2 projectors + cheap foil filters

I was thinking about using two of those in polarized setup, because they are relatively cheap with such resolution.
Must be interesting to align 3 of them. Although, idea is not that bad. Just, these heavy glasses ...

Go for it !

It`s new world !

BTW - with polarized setup you have to just add filters and very light, comfortable glasses. Screen is also cheap (doesn`t mater what kind of screen you will pick up it always cost almost the same as normal white one).

3D Vision - you have to go for another projector, second GPU (for Sli to get access to third connection and extra power) and 3D glasses with IR Emmiter. Also some quality white screen. All this is quite pricey.

That`s why your choice is quite right.

In first post there is a list of equipment needed.
However, I am unable to find which graphic card configuration is used for this.
Two graphic cards or dual output graphic card? It is probably dictated by 3D drivers.

One GPU with two DVI-D outputs. At the moment IZ3D drivers can not work with outputs from two different cards (they will be soon but not now). You have to use extended mode for your Windows desktop (instead of clone mode).

Is it possible to use the card with one DVI and one HDMI output?

Yes, but be sure that your projector have an input for HDMI. It really doesn`t matter what kind of connection you use - it is all about dual signal from your card. It has to be able to run extended mode for two screens (this is when you have two outputs from GPU).

Did you speak with NIMA about his 3D project ?

No. I prefer to go polarized way.
I am fighting to find screen on local market.

Interesting feature - automatic alignment of projectors in SW

Hi Skaut69, I have a question about your anodized aluminum screen. How do you feel such a screen would work for watching movies in 3D? Also, how about watching movies and playing games in 2D, will it work equally well, or will it be a distraction?

I am already watching every new 3D Movie on it and also 2D. It really doesn`t matter what i am doing on it - always the same best quality. I did give up on my old white wall ( perfectly smooth and snow white) and stick to this polarized.
Lately i was watching Resident Evil: Afterlife, The Hole, Alice in Wonderland...and others. I`ve also seen Avatar and i felt exactly like i did in IMAX Movie. Clear, sharp, perfect picture.

You and all guys from forum have to know one more thing about this screen. Usually polarized solutions have something like Glass Wall which you constantly see betweene you and the 3D enviroment, let say behind screen. It is because of the surface being not so clear. My screen ain`t got enything like that. You can watch it from very close distance and only thing which you will see is deap 3D space befor you. Just excellent !!!

Picture this: documentary movie Under the Sea - all this fishes swimming in a big fish tank in your room and some of them literally swimming out of the screen. It wouldn`t be possible with this Glass Wall effect.

So i am recomending this like nothing else !

@Skaut69
Could you please list your complete setup? I know there is a list in your first post, but that setup seems pretty similar to Cleeve's setup in his article on Tomshardware on March 30. If I remember correctly he was not able to watch 3D movies, except when converted from 2D to 3D, using TriDef.

I'm especially interested in knowing which software you are using for movie playback. Are you playing Bluray movies?
What graphics card are you using for multiple output and which software did you end up with to split your left and right screens?
And what is your current screen made of? Are you still using the aluminum sheet or did you buy from Awater after all?
What about your polarized glasses? Can I assume you are not still using the glasses from the test setup in your first post?

Maybe you have answered some questions already, but I'm kind of lost.
Thanks in advance!

Movies converted by TriDef drivers are worthless. You hardly see what is all about and constantly struggle with crossing view. Focus yourself on other solution. Since there is no software which works with dual projector system for 3D Blu Ray Movies, you have to go somehow arroud this. So this is what you have to do. Your movie is on 3D Blue Ray disk. You work with this by DVDfab software to compress it to different format (one file). By this software you can achive almost the same quality as Blue Ray. Your movie will be recorded in Side by Side view (depends on your choice) for each eye. Process is really easy.
After that you have to go for Stereoscopic Player. Here you will choose what is the file (Side-By-Side, Over/Under.....), what is your output (Dual Screen Output) and other. You can make a test. All this softwares have a Trail for about 30 days so you can download some short movie from Nvidia site which is usually recorded SBS and set it with your rig.
Be aware of the settings. Stereoscopic picture will be only seen in Fullscreen mode and you have to switch between left and right view (which shown as a first - by F7 key) if you will see disturbed picture. In View you have to pick Dual Screen Output in Viewing Metod and remember to set what is the file after load (if software will ask you to provide this information). If player will not refer to file at the beginning you can go in File to Video Properties and set it yourself. It doesn`t mater which view you will set as the first one - you can always change this when movie runs F7.

I am using Nvidias GeForce GTX 480 in 3-Way SLI - but one card will do the job. Only thing you need is dual output (DVI-D) on your card and Windows desktop set to extended mode.
You know software for movies content. In case of games i am on IZ3D Drivers. All the best about this people ! They love it same as we do.
I am still on this Aluminium Anodized screen and i don`t think about changing it. It is just perfect. I will be recommending this one to every one as a cheap solution - better then any paint or even some of the polarized screens.
I have few different glasses at the moment and i have some informations to share with everybode about them - so i will post my test as soon as i will get my camera work with my stupid system.

One thing before you start with polarized system. Three different types of filters. Circular (which i used as the first one in this post) second Linear which already are in two formats: 45° degree angles and 90. You have to be aware of that when you buying - keep all filters in the same type. I am on Linear 45.

GLASSES

These are all glasses i`ve purchased from berezin.com. I wont be very revealing if i say that quality matters a lot.
All them are Linear 45 degree and all made from plasctic (filter) so they suppose to work exactly the same. Only difference is in case of qualit of the plastic/foil which was used to make the filter. All them are comfortable because they are light and well shaped. Sometimes frames might be visible (didn`t annoy me at all) so frameless ones might be better chioce for some of you. Basically difference in experience is about how dull picture will become and how many distructions will you experienced.

1. Jumbo Theme Park.

As first one i`ll pick the worst. These are the only foil ones. Lens is so crappy that everytime when you move you can see all reflections on theirs bumpy surface. Also they are really hard to clean and very easy to damage.
From other side it is good choice for a movie sessions. Friends wont be stress by you to keep them safe. About 4.50 $ if you buy more then 10psc.

2. Terminator type.

These are well made and good looking ones (like you need that 8) ). Since shape is nice you have to expect some restrictions. Lens is to small and this means that frame will be seen like hell. More is that they are quite thick so those who don`t like that will definitely complain. Also lens is darker then on the others so be prepered to see bit more darker picture (still a lot better then 3D Vision experience).

3. Aviator.

I am using them all the time. Frames are made form thin metal so they are hardly seen and very strong. Lens is thick and very bright (almost like glass) and also easy to clean. Quality is comperable to those on the projector. Superior visibility and quality experience !

4. Clip-ons.

This are basically the same as the aviator just without frames. Great quality in case of lens - no reflections, clear and bright picture. For some of you there might be a problem with this mounting system. Since i still dont know how it was ment to work with my nose - i manage other way. Thin rubber arroun head and glasses attached to it by clip. Also this clip is quite visible when works in normal way so it is better when i flip it up to grab this rubber.
Basically great glasses and definitely best solution for those who feel restricted by glasses itself in case of Steroscopic 3D.

Great explanation. Thanks!

One more question, isn't it too noisy to have 2 beamers on at the same time?

.....compare to what - two SCN5 ?!
I`m joking. They are quite noisy (fans) but not much then other parts in the room. Some time ago i was thining about some cabinet to close it in ther and also make a separated ventilation to outside of the room. They can heat up whole room in one houre to make you feel sleepy. Bad air ionization.

Oh yeah, there's that too
Thanks again.

Maybe someone can give it a try.

Glasses-Free 3D Gaming for $5
(DIY Autostereoscopic LCD Monitor Mod Using Parallax Barriers)

In this tutorial I'm going to show you how you can convert your regular LCD monitor into a glasses-free (auto-stereoscopic) 3D display. To do this we are going to use what are called Parallax Barriers. This is the same technique used on the Nintendo 3DS. Please make sure to watch the video above so you have an idea of what we are doing here. I also quickly explain what a Parallax Barrier is and how it works. Basically what it does is selective block certain pixels from one eye or the other. So with properly authored content, we are able to deliver one image to the left eye, and a different image to the right eye. This concept is actually not anything new, it had been discovered over 100 years ago. However it is just recently being applied to commercial products. In the next year years I think there will be a lot of development in this space. Specifically with portable devices like the Nintendo 3DS. But you don't have to wait for companies to bring this technology to the home. You can start gaming in stereoscopic 3D, glasses-free, today and you can do it for less than $5. Well, technically, you do need a certain amount of supplies and tools in order to complete the project. But the actual parallax barrier itself and the ink you use to print it will only cost a couple of bucks. Ok, so here is what you need

LG Display declares Active Shutter 3D TVs a health hazard, begins massive Passive 3D offensive

LG found itself at the centre of a 3D storm at this week's CES, with its Display division warning of dire health consequences for users of Active Shutter 3D eyewear. 'It is not safe to place batteries and electronics so close to the brain,' proclaimed a spokesperson unambiguously, before tub-thumping the benefits of Passive Polarisation 3D TVs.

SONY HMZ-T1 HMD 3D UNIT
This is something what might fit into our needs. Its like Virtual Reality or maybe not that far from it. Basically it`s Stereo 3D head mounted unit which generate quite big field of view. Read review to see what is all about. Someone mentioned this before but right now its on sale and works with Nvidia GPU so you can also read someone`s experience on theirs Forum. Go for it and try to make it work with TrackIR - i personally need some info about how it works in this combo.
