I was hoping to find a solution that didn't incur that extra $200-$250 expense (and effort) of ceiling mounting. I don't believe that was included in Cleeve's pricing of the sub-$1500 setup.
If you are wanting to go cheap, I think Newegg has a Universal Ceiling mount kit for projectors for $99... I am not sure that it works for all of them, but It might be worth a shot.You guys are shopping in the wrong places Monoprice.com has one for $17.

You can also get 25' and longer VGA cords for under $20, they are of high quality, I percieve no difference between a 3' cable and the 25' cable.
Awesome!! Have you used this particular Unit? How sturdy is it?

I definately wouldn't say that the 1080p BenQ W9000 DLP projector I'm thinking about getting is about $3,500 street price. (100Hz).
Unfortunately the 100Hz you are quoting will only be the maximum vertical INPUT video frequency. The maximum DISPLAY frequency is still likely to be just 60Hz. There is a big difference between INPUT frequency and DISPLAY frequency. If you input a 100Hz signal into this projector, it will internally convert it to 60Hz, and totally destroy the 3D effect in the process.
However, I'd like to be proven wrong. Have you tested this unit?
| Quote : I'm still possibly interested in the passive polarised option though. Will this method work with LCD projectors as they are cheaper than DLP (I presume it would as they pixel decay time isn't relevant for this method) |
Correct. The other advantage of LCD projectors for a dual projector polarised setup is that it's easier to find projectors which have lens shift. Lens shift is very useful to obtain good stereoscopic alignment.
One advantage of the single-projector DLP 3D setup is that stereoscopic alignment is perfect everytime - no adjustments necessary.
| Quote : thanks for the input. actually, it's funny you mention the DIY projector project, as I built one already based on the old article on Tom's Hardware for building one with the overhead projector (I was looking all over lumenlab's website at the time). I did it on the cheap with old LCD's from ebay, but I had a hard time finding a used projector so bought a new lower-end one. The results are pretty good, I have it set up in a small room and built a homemade screen with a queensize bedsheet and cheap white shower curtains sewn together to make a 2.5mx2m screen (HUGE!). |
Sounds good.
| Quote : I have read lots about people building enclosures for their LCD projectors to make them more visually appealing and more portable, but my engineering skills are lacking to go to that extent, and that's the only way I could see using two LCD projectors in tandem to be a practical cost for me currently, though adding an enclosure increases cost too. As for the mirror method with two monitors, I'm pretty happy with my 22" LCD and would be hesitant to buy a second 22" monitor I'd hardly use anyways, except for 3d gaming when I want it. I also watch a lot of television and movies on the computer, which would require removing the apparatus I suppose and I'm pretty darn lazy. |
No need to remove the apparatus, just flip up the mirror and hold it with a catch.
You can also run 2 screens at the same time and double your desktop space
, so it isn't a total loss.
| Quote : HOWEVER, after my tour in Afghanistan starting January I'll have some money to spend, so I'd love to see some new Nvidia drivers and figure out a practical way to implement this (likely with a new store-bought projector). I certainly have a lot more reading to do if I'm going to make an informed decision about which method to use (if any), so far I am only basing my information on what scraps I've figured out from posts in this forum. Hooking up some wireless shutter glasses with an inverter and installing a driver sounds just too easy to consider another method using mirrors, dual projectors, fresnel lenses or whatever else, unless it makes a truly dramatic difference (this is just in my house for fun after all, i'm not doing professional presentations or charging admission). |
Have you been to Barry Aldous and Planar websites? Barry makes it look as easy as it is.
You don't have to make a box out of the monitors, you can just have them on an arm like the Planar setup.
"so far I am only basing my information on what scraps I've figured out from posts in this forum", doesn't sound promising, as I have linked to some really good sites full of DIY setup info.
So you want the link to the guy from Spain who made his own setup?
On Lumenlab forums right now is a guy called "tescorp" He will make a fully-loaded enclosure (just add the LCD panel) for $400 in the 15" size (1024x768), or $425 for the 17" size (1280x1024), that is surely one way to do it, get two of those.
Mirror one of them, project both onto a silver surface, put on the glasses, enable the mirrored Dual output mode on the video card driver panel. Enjoy the 3D.
Enjoy, I hope you find a setup that matches you, and of course do some work on Google and make sure you are doing it right, whichever option you choose.
don't worry, I will be looking over all of your links, as well as doing additional research. I'm in no rush currently.
It's too bad the DIY projector option only gives 1280x1024 (I know that's an LCD panel limitation), so no HD for the future right? Or if I project them side by side and get twice the resolution that'd do it I guess, except that I'd imagine a single manufactured projector would easily use 1/2 the power and take a lot less space right? Especially since I won't be buying till September 2008, at which time my options will probably be completely different.
Maybe I should not even be in the discussion with my timeframe in mind, but I find it really interesting nonetheless. I really enjoyed my simple DIY projector project, and my family and friends really enjoy it along with surround speakers. the 3d effect sounds so interesting I'm tempted to jump at it.
Any panel you can get to fit, the guy with the 19" panels from spain (plog section of lumenlab forums) has 1440xsomething display, really HD.
That is the beauty of DIY, you can make anything.

No I haven't tested it. I think you may be right, I may have been quoting input refresh rates. Where would I get the output frequency specs for a projector. I've never seen those listed in a manual (or if there in there I don't know what to look for)
| Quote : Where would I get the output frequency specs for a projector. I've never seen those listed in a manual (or if there in there I don't know what to look for) |
I have never seen "maximum display refresh rate" or "time-sequential 3D compatibility" listed on the spec sheet of any consumer DLP projector - just on the 120Hz 3D capable projectors from DepthQ, Barco and Christie.
The only way to find out so far is to test it. I have even asked the distributors or manufacturers on several occasions and they don't know.

that's pretty pathetic the manufacturer does not even know the specs for their product. I just love when manufacturers omit specs or even give you useless specs like voltage/wattage for a vacuum, when amperage is what determines the motor's power. You'd think they would at least make the effort to ask someone to check it out for you at the manufacturer.

I'm particularly interested in what EveOnline would look like.
Q
add my vote to curiosity on WoW. the reviewer could get a $5 try-before-you-buy WoW license from any best buy or whatever for I think 10 days? plenty to try it for the 3d effect. I'd be very curious to know if it looks good, and if the interface works out ok (it's got a whole lot of icons after all).
I play WoW with shutter glasses. The only thing is that you have to turn off the vertex shaders (all vertex shaded objects get rendered at 0 screen depth) and on some machines the fullscreen glow effect (not sure what the delineator is for that). You lose a few frames of performance from the vertex shaders but it looks great. With the settings I use the interface is at 0 depth an it looks like you are looking down onto a live, toon battlemap. I was surprised that by far most of the spell effects are actually fully 3d rendered. The exceptions to this being "bubble"-type spells. The weather looks ok... but feels like it is also rendered at 0 depth... still gives 3d illusion by rain/flakes disappearing at different virtual depths. Water looks really nice, but after a bit you might notice that it's a pixel shader on "cloth." Boss creatures look phenomenal... particularly of recollection is Hakkar (can't get over the sheen). For the few who play WoW in 1st person, it is also possible to set the frustrum and spread to get that looking very nice (may require remapping of some keys either in game or for nVidia driver). Skies are a bit of a let down... then again even without shutter glasses they weren't as good as they could have been. I also remember the awe factor the first time my rogue got poisoned when I was wearing shutter glasses... each of the little skulls is 3d rendered. All-in-all lots of eyecandy.
Nubie : I just tried out my first stereoscopic rig, and I'm so impressed that I am already thinking of upgrading to the next level. I'd like to talk to you about building a TARDIS, just need 2 LCD monitors from newegg (good ones are $250 each for 2-5ms 1650x1050) and that teleprompter mirror glass piece - not sure the exact dimensions, but easy to calculate. A quick system of equations for figuring out the horizonatal and vertical.
I have a few questions, though. Considering how much more interesting to the eye and immersive 3d gaming is, has anyone else build a rig like this besides Barry?
I'm also a little hesitant because since stereoscopic gaming is so rare, games often do something to mess it up, and nvidia doesn't prioritize writing stereo drivers. Finally, the best possible stereo support would be with SLI drivers where each card renders the frames for one eye.
But, I don't think drivers do that, and the most powerful card (8800) is not supported, so it isn't even possible to run the most graphically intense games in stereo.
Also, most pixel shading effects seem to break it, as well, as shadows never working, and so on.
Update: did the math :
11 3/4" x 18 3/4" x 1/8" Teleprompter Mirror - $53
Wow, so to put together a basic setup might cost less than $100 to make the assembly, and I could test it to make sure the concept works with a couple of laptops I have for free.
Interesting article.
One thing though. the reviewer does'nt mention stereo convergance keys.
He suggests seperation at 10% to cope with 'near object' focussing.
I find this takes away a lot of the 3d effect.
I prefer to have seperation at 100% and I adjust 'near object' focussing by adjusting the convergance instead , which retains the 3d effect better, but enables me to focus on near objects(such as guns you are holding)
and also, isnt there a piece of software to switch the right/left eye display, instead of the hardware solution suggested?
Anyway, I enjoyed the article. I have used 3d shutter glass from edim for about 4 years now and definatly want to get a projector!.
...and while I was sleeping on it, it suddenly dawned on me I already had all the hardware I needed to give it a go here too. Which I did the next evening.
It does work, and it sure enough IS gorgeous.
--------
The only thing I've tried it with so far is my main gaming application--a niche racing sim called "rFactor."
(rFactor.net)
Don't see why it wouldn't work too, though, with other 3D titles--I have the "IL2/Forgotten Battles/Pacific Fighters" series in mind certainly....
I'm running a particular flavor of rFactor lately known as the "79 mod," (Grand Prix/Formula One cars of 1979), and this setup puts me IN the cockpit of my Williams FW07...or my Brabham BT-49...like nothing I've ever tried. Spent last night driving around Monaco, and I can safely say I've never felt like I was sitting inside the car to anything like this degree before.
I fear it may ruin me, too, for normal CRT/LCD screen driving, and it does also point up shortcuts and tradeoffs taken by some 3D modelers, but that's the price you pay for moving up to the 3D big picture I suppose. I'll gladly pay it.
Thanks for the comprehensive article, THG.

Can anyone post some stereoscopic screenshots of some of the newer games?
I'd like to see what it actually looks like.
Thanks
Great article, keep 'em coming!
Question: I was wondering if anyone else has had experience with the i-art glasses:
http://www.i-art.com.tw/ENG/Produc [...] es_Eng.htm
Am I correct in thinking they wouldn't need a separate inverter? And how do they compare to the edimensional ones? Comfort? Quality? And will they work with a projector? I understand they will work, using the Nvidia driver, on a CRT but not an LCD but what about a DLP projector like the one in the article?
Thanks!

You will require some form of stereoscopic viewing equipment to view a stereo image as you have to have 2 images - one for each eye.

I have some stereoscopic screenshots of Painkiller, Need for Speed Underground 2, and Lego Star Wars that I can upload if people are interested. They're not the absolute latest games but never-the-less display some good stereoscopic effect.
They're in JPS (Stereoscopic JPEG) format.
JPS images can be viewed in 3D using a few different applications: JPSViewer (part of the NVIDIA Stereo 3D Driver), Depthcharge (from www.vrex.com), or ...
The beauty of the JPS format is that it can be viewed using almost any 3D display/glasses that you can get your hands on - including anaglyph (red/cyan), shutter glasses, or even autostereoscopic displays. The JPS viewer application converts the image on the fly.

Yes, just to let you guys see my first Dual LCD Planar setup (this is actually two OEM Planar units badged as Hitachi CML175SX and CML174SX, one has speakers).
Check out this awesome effect, if you can cross your eyes and focus on the two screenshots below of my actual monitor (through each lens of my polarized glasses) there is a 3D effect! It is like seeing my actual desktop!
I basically cross my eyes until they are lined up, then "relax" my eyeballs to allow them to focus, otherwise the muscles pulling them cross-eyed deform my eyes and defocus the image. Note that it is easier to do if you are a foot or two back and are used to viewing cross-eyed stereo pairs. Either way the proof is in the pudding, no ghosting and high contrast for direct view. Even with a picture, (hey, there weren't any pictures in that article, how do we know what DLP 3D looks like?)
I set it up in a horizontal setup to check the effect. Unbelievably brilliant, high res (1280x1024, x2), ZERO ghosting, lightweight comfortable glasses. It kind of helps that these are top of the line monitors though. I got them for ~$50 apiece on ebay, I had to get 3 and swap parts around, I had a broken LCD, a dead Inverter, and a dead set of back-light tubes, so out of $150 worth of junk LCD's I salvaged 2 sweet ones.
I wasn't prepared for the effect to be visible from many angles, but as you see from my screenshots the effect works anywhere you are looking through the mirror. I need to put back in my hard drive with Oblivion and Tomb Raider: Legend and World Racing 2, Serious Sam 2 etc etc.
I do plan on mounting them eventually in a Planar style mount: http://www.planar.com/products/fla [...] reoscopic/ Note the $4,000 price tag and I get the same effect (with the same screens) for under $300
.
All you need to do is get the pictures mostly aligned, it doesn't have to be precise as each eye will see a completely different diverging picture anyway, just having the screens aligned horizontally is enough, and in a vertical monitor arrangement the mirror can perform that alignment, if you look at the Planar monitor(s?) you will see that there is an adjustment screw for that purpose.
Don't forget that the source for the mirrors is http://telepromptermirrors.com/
Notice that the Planar commercial jobs have a truncated (short) mirror, that is because you will be looking down at your screen, and the extra mirror is useless because all you would see through it would be your Desk, and a reflection of the ceiling. Take that into account when you measure for the glass.
You can do a mockup too with a mirror or a piece of cardboard, hold it where the half-mirror will go, if you can't see your monitor screen, then it should be big enough, the regular mirror method works if you have the mount already made and you want to see the top screen is reflected.
Best to get an extra couple inches to be on the safe side though, and they will cut it for you to any size, so that is good.
This method will theoretically work on any size screens you can get, I would love to see this in a dual 30"
, obviously that would be expensive, but the quality would be absolutely stunning.
Try a dual 15" one for starters, there is a good chance you can borrow a second screen at work and give it a go, or borrow one from a friend to test the waters as it were. Once you are convinced, get a couple sub-$200 19" monitors and enjoy. If you are already using an LCD that didn't cost you an arm and a leg, you can get a second one and be good to go.
If you make the top screen flip up or detach for desk use you can have the luxury of dual screens in normal 2D windows tasks as well, that is how I am typing this up, managing mp Picasa on the left screen and typing this on the right screen.
I think that the dual LCD method offers the most bang for the buck, it is high contrast, high res, Zero ghosting, zero flickering, and can be easily set up for under $500, including a handful of spare glasses so everyone can watch too. If anyone wants to know my driver setup, it is the 91.31 Stereo drivers and the 93.81 Forceware on a GeForce 7900GS. If anyone is looking to do this I recommend a 7900 series with 512MB of ram, I have basically modded my 7900GS up to the GTX clock speed, but I can't double the ram. I got it for $120 so it isn't all bad, but a 7900GT/GTX/ 7950GT etc would be an ideal card. The 8600GTS is about level in terms of performance with the 7900 series right now, so you don't really lose out on playability.
wow thanks for the post. I REALLY want to see this in action, but no matter how much I cross and uncross my eyes I cant see anything 3d in your screenshots.
i hope nvidia/ati release some new stereoscopic drivers soon. Unfortunately they seem to be having enough difficulty just making vista drivers right now, never mind stereoscopic ones.

Actually, I don't have any stereoscopic glasses but I can see the stereoscopic effect just fine if I have two screenshots side by side like the ones found on http://www.stereovision.net/toxicx/start_shots.htm
I would take the screenshots myself but I don't really know how.

OK, you have to cross your eyes a very small amount and try to line up the Tony Hawks in each eye, I have three sizes, back up a little and try the smaller picture if you are having trouble.
I can see each one of these, it seems that as you first cross your eyes that you go way overboard, so you have to carefully come back until the pictures line up.
| Quote : i hope nvidia/ati release some new stereoscopic drivers soon. Unfortunately they seem to be having enough difficulty just making vista drivers right now, never mind stereoscopic ones. |
They just did, but only one guy reported getting his 8800 series card to work with them. Nvidia are working on stereo drivers, if that is any consolation. The beta drivers are at http://www.mtbs3d.com , note that you can replace the inf file and install them for an earlier video card, and as I said, the 8800 series don't seem to work for most people.
EDIT:
I just realized my mistake, I should be using the 93.71 stereo drivers http://downloads.guru3d.com/download.php?det=1511 , I had them downloaded and installed on a different hard drive and they work much better.
I highly recommend these with the 93.81 Forceware drivers, they work very well with a lot of games.
Will01:
Yes, the i-Art "Wicked Eye 3D Premium" set is exactly what I use, and yes, with this setup you do not need the stereo projection inverter from 3DFlightSim.com (I'm running with the Nvidia 91.31 drivers-1024x768 native @85Hz, which is the highest rate my projector can stand).
If you select that model from the link you provided you'll see the Eye 3D Premiums include the "TX4000 Infrared Emitter Box." The button at the top center right switches the strobing order of the panels (I imagine you already know this, which is why you have the i-Art setup in mind--good choice).
I'd be surprised if any i-Art combo which includes the TX4000 doesn't work equally well too.
It's roughly a $100 savings over the setup used in the article, offset of course by the higher cost of the two pair i-Art kit. Moreover, it will work with wired glasses too.
So far I've only tried the wired pair here (with the projector)--they plug into the right side of the emitter box, and there are connectors for two wired pairs--but I anticipate no real issues using the wireless set and the switcher button through the infrared sender. The wireless glasses worked just fine together last year when I was using them with a 21" monitor, and I definitely made use of the panel switcher button even back then.
The i-Art combo cost $200 when I bought them several years ago from a US distributor, although back then the additional shipping cost was pretty minimal. Seems to be pretty steep if they must be sent direct from Asia, so I'd look around for a distributor somewhere on your continent....
---------
ADDENDUM: I found my pair of wireless glasses again too just a short while ago, and they have what appears to be another stereo panel switcher button located on the RF receiver unit. Which gives you two ways to switch the strobing order of the panels.
I'd forgotten too that the IR receiver plugs into the left corner of the frame, but is removeable, so in theory you could even flip it over and mount the IR sender unit vertically above your head...or behind your head...and still manage to make them work. Might require some sort of homebuilt extender to the plug, yes, but's it's doable, at least on paper.
For the life of me I cannot remember for sure if I used the swithcher button located on the IR receiver or the one located on the TX4000 unit when I used to toggle the glasses, but I have the vague idea I used to reach for my vest area to toggle the order...which suggests I did use the button on the IR receiver.
It really doesn't matter though--ONE (if not both) of them should, indeed, do the job (so again--you won't need any other inverter if you use the i-Art glasses).
As far as comfort: I use mine over the top of my normal glasses, and while the ear blades are bit thin in vertical cross-section (thus tending to irritate the top of the ears) I don't see any reason they couldn't be "padded" with tape or fabric as required for comfort. Just haven't bothered with that yet here.
The biggest drawback to these particular glasses (over eDimensional or Elsa) might be that the glasses frame surrounding the polarizer panels is solid, and thus opaque--seems to me something manufactured in clear plastic might work better with any surround projection image to further increase the sense of "being there"--you'd see the additional peripheral projection too more easily anyway.
Not a show stopper though, and otherwise, I'm pretty happy with the i-Art glasses (both types).
I do have to wonder also if the TX4000 sender wouldn't work with a pair of the eDimensional glasses (either type)....
C_S
thanks very much for the additional pictures. I believe I was able to manage it now with the large and medium picture size. Basically at the right amount of eye-crossing, I was able to see a 3rd centered image in focus while the other two were blurred. It did seem to have more depth than the other two, but only by a bit. I would imagine that's because the images are so small compared to my overall field of view.
Glad to hear that work continues on the drivers (too bad only with nvidia). I'm hoping this will be improved further with the latest generation of cards by the time I am ready to buy this stuff in September 2008.
Did anyone tried Google Earth with 3d? I imagine it is nothing less then great but can someone give a feedback?
Did anyone tried EVE ONLINE?
How good is that in 3d?
thks
Guys, all this talk about stereoscopic games made me very excited about aquiring my future 3D rig.
BUT (there is always a but
I am a bit unsafe about the resolutionsyou are talking about here.
To start I am in Brasil and most people (includemyself) still use CRTs, and since I am about to buy a completely new rig I was seriously thinking about to go for a more imersive equipment until I saw this article. My set up was to be 3x 19´ LCD Display with a Nvidia 8800 and triple head to go.
But LCD resolutions always concerned me a little bit because they are fixed instead of CRT that we can choose from a variety of resolutions and they all look great (or almost).
Then I saw this new aproach to displaying 3d games but the resolution goes even lower. I mean in CRT we can use very easily 1600x1200, then in LCD goes to 1280x1024 and now the best projectors under $1000 can display maximum of 1024x768.
My question is: isn´t it such low resolution to display such ammount of details in the games? Games are always evolving to display more and more details and the graphic cards are evolving also to keep the run.
Can I get the same level of details with 1024x768 in a projector? will I be missing something compared to 3x 19´LCD with 1280x1024?
This is my first point risen to discuss, but there is more.
1-I thought if I am going to loose details then can I use Triple Head to Go to link 3x Projectors at 1024x768 and use them with stereoscopic 3d games?
2-Well does not need to be 3 projector, 2 can be just fine. But did anyone actually tried it?
3-Can I use 2 projectors WITHOUT Dual head to go BUT with simple two display output from the graphic card?
The only problem so far I see using the triple head to go with 3 projector is the fact that even each of them being 85hz the triple head to go downgrade them all to 60hz, is this really a problem since eyes can get 30 fps?
One problem that may immediately pop up...
Last I knew, most shutter glasses use the DDC pin of the DB15 connector to sync. Since you would now potentially have 2-3 sources for sync, the only way of which I can think to overcome the problem would have to be done through the driver. Even at that, you would see an fps drop as everything would have to sync to whichever display was taking the biggest performance hit at the moment (thinking to the future of gaming if not immediately since an 8k series card is fairly powerful). If the driver is not written for this then you can expect some weird happenings such as:
Flicker on the displays your glasses are not plugged into
Stereoscopic inversion on the displays which your glasses are not plugged into
Rolling bands (like when you use older or lower quality camcorders to record a monitor or TV) along with the prvious 2 problems
If you like resolution for the sake of sharpness you won't have much problem with the lower res. If you like it because you play games where being able to tell the difference between something that's 1 pixel vs 4 pixels in size can make or break your game ( which I imagine not if you were already contemplating 1280x1024) then you will have problems.
As far as refresh rate, for most people the breakover point is somewhere between 72 and 85 Hz (in my experience). Those with faster eye-brain communication may have issues even at this high a level. Something to keep in mind is that even though TV's may only change the image 30 times per second it's actually refreshing much more than that. That is to say 30 frames per second is the accepted standard for fooling the brain into believing there is smooth motion, but 60 refreshes and up is a must for preventing eye fatigue. Recall that shuttering halves the effective refresh.
Is the Optoma EP1690 recomendable? will it work with stereoscopic 3d games?
Thanks again
Felipe

Google earth doesn't work in full screen mode, so it doesn't support 3D with the current nvidia drivers.

Google earth doesn't work in full screen mode, so it doesn't support 3D with the current nvidia drivers.
"Dynamic Digital Depth" has released a driver which allows Google Earth to be run in full stereoscopic 3D. More info here:
http://www.tridef.com/promotions/google-earth.html
However, for frame-sequential 3D you will need a NVIDIA Quadro graphics card. From memory the Tridef software is only capable of supporting anaglyph 3D on the NVIDIA GeForce cards.
Some screenshots of Google Earth in 3D are also on the page listed above.

Or you can install NVstrap from Rivatuner (guru3d.com) and then the Quadro functionality of any existing Geforce is unlocked.
The chips for Quadro and geforce have always been the same, it is in the software and sometimes the bios that the quadro distinction is made.
As for the fellow above me from Brasil, do some research, the 19" monitors are 1440x900 or some such, you can turn that into a Projector yourself with a kit, use two and you can do the polarized 3d.
Do some research, use the Anti-Aliasing modes. 1280x1024 is just fine for gaming. I don't know what you are expecting, just get a single wide-screen 24" LCD would do you fine. 2 if you want to do polarized 3D.
Get a 7900 series card for 3D right now, overclocked with 512MB they are just fine. NOT the dual card 7950, but the regular 7950GT 512 should be fine. I paid $120 for a 256MB 7900GS, I clocked it at 650Mhz core with a Zalman and ramsinks, it does fine for my dual 1280x1024. (If you think about dual polarized projection, each eye sees 1280x1024, so it is really double the resolution).
Use 19" or 20" screens and you will get 1680x1050 or 1440x900 or 1440x1050.
The 20" model is only $270 new, get two and the mirror and the polarized glasses and you can make your own one of these: http://www.planar.com/products/fla [...] SD2020.cfm
I keep pointing out the benefits of the dual LCD polarized setup, IE high resolution, totally passive glasses, the inexpensive nature of high quality large high res LCDs.
No cords, no sync issues, no batteries, no flickering, no ghosting, anyone can watch with a pair of glasses, up to as many as can see the screen.
Get a couple refurbished or used LCD screens and the price drops significantly.
NVIDIA CARDS HAVE DUAL OUTPUT FOR A REASON, THAT REASON IS TWO DISPLAYS. ENGAGE YOUR BRAINS AND QUIT ASKING!!
God forbid that anyone actually reads the User manual on the video card you spend $xxx on. Or reads the driver manual from Nvidia.
RTFM, google that please.
I should drop this thread, I am getting tetchy with people who can't read.

Thanks for the tip about NVstrap.I thought tetchy covered rude
(Edit, I meant tetchy, sorry)
I guess it was nvidia forums where 3 people in a row asked if you needed 2 cards for dual display, and then one guy asked about if he needed a third card to mirror one of the 2 displays for the 3D
I suppose I could edit out the rudeness, but how dumb do you have to be to not think
"hmm, two outputs = two displays?", and then "maybe I will read the manual", and then "oh, all that paper in the package that I paid for has a purpose, to tell me things that I need to know".
I messed a little around with stereo and treied this planar Systhem with 2 CRT Monitors. This works ok, except with C&C where -if there is any 3d - the mouse isn't mirrored on the 2nd monitor. Now I read Google Earth could be 3d and want to try this.

. Now to get back to the topic. I would love to see how FEAR looks on this. It really would be like being in a horror movie. Try it out if you can
Hi alik4041,
FEAR needs a little tweaking to run properly, because it uses post processing. Especially in Slow Mo this kills the 3d Effect unless you switch to DX8 mode somewhere in the menue.
Here is a thread about it^^
http://forums.stereovision.net/vie [...] &forum=5&6
My problem was just, that it had a some "ghosting" on my CRT. When I'm standing next to a white wall and are watching into the black corridor at enemys, I can see the white wall twice, because the phospor needs some time to get black again.
But in my opionion it is very well playable if you use the Nvidia Laser Sight (normal crosshair is crapp in s-3D) and ignore the gosting or increase gamma (a lot) for additional brightness.
On a DLP beamer you shouldn't get any gosting, right?
In my experience so far, you still DO experience a bit of ghosting with a DLP projector, even at 85Hz refresh, yes.
Not really sure why this occurs either--it certainly isn't because of glowing screen phosphers. Might instead be something to do with afterglow effect in the rods and cones of the eyeballs? That same "afterglow" effect you get when you step into a brightly lit room and suddenly shut off the lights....
I will have to say that it's pretty minimal in my view. No showstopper, certainly.
Bigger issues to me might be that some colors tend to shimmer more than others--yellow seems the worst, but there is some of this effect too with red and green.
What causes this sensation, I think, is the fact that the two eyes see some objects displayed with different levels of color (and I would guess it has to do with the rotating colorwheel timings rather than the actual throughput of the signal in Hz). So I'll see one billboard as bright yellow, for example, with the left eye, but only a dirty brown with the right eye.
While the two eyes will agree on the stereo placement of the object in space, they won't agree on the color of the object they are each seeing. Thus they instead agree only on an object that will seem to shimmer and dance to some degree.
I have the idea this problem might be solved by re-engineering the projector so that the colorwheel speeds were all doubled, tripled, or quadrupled, but if we try that we're now heading off into the DIY/experimenter realm. Not really just "off-the-shelf" stuff any more.
---------
On the plus side, I have to say it's the LIFESIZE stereo projection which really makes it all worthwhile for me. I've used shutterglasses in the past for driving, but even with a big (21" ) CRT monitor located right behind my wheel, I just couldn't quite buy into the idea that I was sitting inside a real car--the stereo effect, colors, and resolution were all quite good on my monitor...but everything seemed considerably "undersized" at the same time. Felt like I was driving a large (1/4 scale) RC car instead of a real, full-sized, automobile.
With lifesized stereo projection, however, that fundamental disconnect has finally been bridged over, and my brain buys into what I'm seeing pretty thoroughly at this point.

I've been thinking of ordering a pair of e-dimensional 3d glasses but the thing holding me back is the way counter-strike: source looks
i installed the stereo drivers and took some jps screenshots and i can clearly see the 3d effect just by having the stereoscopic double image side by side
the crosshair, kill info and chat msgs are double, this is quite annoying
is there a way to fix this? at the very least, i need to see my crosshair
also, in marvel ultimate alliance, the minimap and the hero interface are also doubled
if you guys can suggest a fix to this, I'm ordering the glasses right away
Thanks
A lot of what you are talking about with doubling is usually due to a combination of stereo separation and convergence adjustment. The convergence adjustments are defaultly bound to the F5 and F6 keys (may require holding CTRL... I forget offhand) and are used to determine the Z level at which sight for each eye should intersect. Usually in situations where the menuing is affected in this manner I use the convergence to set the menu at 0 or very nearly 0 screen depth. Then adjust the stereo separation to add/remove depth as necessary for acceptable viewing.

Great article. I've been totally fascinated with stereoscopic 3D since I was a kid!
But do you really need an inverter? Couldn't you just physically invert the wireless transmitter unit instead?
Inversion of the transmitter won't buy you anything. What I mean is that the signal received by the glasses is essentially the same regardless of orientation (with the exception of line-of-sight issues). You could turn the glasses upside-down, they tend to be difficult to wear in that fashion.
Hey nubie! I just, after settling a legal dispute that could have cost me $300, bought a mirror from teleprompter mirrors and some polarized 3d glasses.
Got the "Terminator" one and 3 amusemark park style ones for guests.
I paid for a mirror large enough for a 24" LCD, though I plan to start with 20" or 22" LCDs.
I am going to exploit a local walmart. They ripped me off when refusing to allow me to return a cheaply made bicycle that rusted badly within days of purchase. So, I am going to abuse their return policy by buying 2 LCD monitors, playing with them for 5 weeks, and then returning them. I'll do everything with cash, and will buy the same displays AGAIN...
Questions for nubie, or anyone else who's gone the dual LCD/planar route:
What refresh rates are you able to get out of the two monitor pairings with your current planar setup?
My assumption (based on the typical 75Hz max refresh for an LCD monitor), is that you are actually seeing ~30-37 FPS at each eye (each eye is refreshed twice for each stereo frame) but I'm wondering if it's just possible one might somehow set things up instead to drive each eye @60Hz (or even 75Hz) and thereby realize an effective "stereo throughput" of 120-150Hz*?
[*Which is actually just 60-75Hz overall, of course]
This couldn't be done with your 6800 video card, I realize, nor with mine (7800GS AGP)...but I have to wonder if something very powerful like a 8800 GTX might just be able to drive a mid-res (1280 x 1024 or even 1600 x 1200) pairing of LCD's somewhere near this range....
[EDIT: Turns out, yes, this powerful single card should be able to drive either of these high rate configurations, although only the 1280x1024 solution will be able to refresh at 150Hz (75Hz x2) in 32 bit color--either color resolution or refresh rate drops off a bit when we move up to 1600x1200--it'll send output at this resolution only @120Hz (16 bit color) or 100Hz (32 bit color).]
--------
The idea then (for me anyway) would be to rig the two LCD's into a DIY stereo projector, instead of pursuing the single DLP projector route.
Thoughts?

Well, I am a bit confused (or maybe you are
).
Since each eye sees only one screen, accomplished optically, not dynamically, there is no difference because LCD panels do not flicker. You can't tell the difference between 60, 70 or 75hz I am running dual 75hz because my monitors will do it. My left eye views an LCD directly, while the right eye is dark, since I have a mirror up the other monitor is displayed in the right eye and to the right eye it appears dark
With an LCD the refresh rate has nothing to do with anything, you can't see the flickering.
I am not using Shutter glasses, merely polarized lenses to block the light from this setup:
As you can see the glasses do all the polarization, there is no flickering at all and you can't tell what refresh rate is set without checking the driver panel or the monitor menu.
Here are some more screenshots. First with no glasses:
Then through the Left eye of the glasses:
The Right Eye:
No trickery, just polarized glasses ($3):
You will notice that the polarization isn't perfect, probably because I am trying to hold a camera and the glasses and click the button for monitor identify and then snap the shot quickly, in practice the contrast is much higher than shutter glasses, and anaglyph isn't even in the running.
So, yes in theory blah blah blah, but I have a 7900GS and it is doing fine at dual 1280x1024 60 65 70 or 75, and you can't tell at all which one you are looking at.
I wouldn't call it more than it is, 1280x720x32-bit @75hz, per eye (dual, or x2 monitors)
I guess I can't help you any with your question, I hope you understand better what is accomplished with this method, there is no need to use high refresh rates on LCD technology with the Planar method.
DIY projectors made out of 17" LCD monitors will be 1280x1024 in resolution.
For projection you need a silver surface screen. I have found some killer ones for under $200 (up to 100" diagonal) here:
http://www.onlyscreens.com/versatol.htm
The prices aren't working as I checked it a minute ago, but you can email the guy, my screen was shipped from the factory new for $142 total.
The eBay seller search (this works, upgrade to Silver Matte at checkout):
http://search.ebay.com/_W0QQsassZmrm71
Da-Lite calls the surface "silver-Matte", so you can reflect polarized light.
When you make two DIY projectors you must mirror one of them and then project both images on top of each other, since you are building it yourself you can make one projector internally mirrored.
I was helped a lot by the Projector Log of this guy from Spain, he is using 2 19" LCDs (1440x900!!) to make his stereo Polarized setup.

Read about some conversion software etc.. for dvd's. Anyone have any information about watching or converting standard dvd movies to 3d, and watching on the systems mentioned in the posts?
Would be great fun to watch.. ahhh.. "private content" dvd's in 3d...
Quite right, nubie. I obviously didn't understand it. I glossed quickly over it searching for solutions to my own questions, I'm afraid--rather too tightly focused on the connectivity issues the other night, both here and in some other forums I frequent. Error mine, not yours.
Your screenshots do clear things up for me and they also show some big advantages to this method where color reproduction and overall brightness are an issue (as they are with most DLP projectors and the shutterglasses method).
Thanks too for the links--that last one, in particular, has proved invaluable already, providing solutions to quite a few other problems. A very useful blog, that one....
-----
As you point out, this method (as used in projection) does demand a higher "quality" of screen, since it must reflect not just light, but polarized light back to the eye in order to work. This MAY eventually be the one stumbling block that forces me to continue instead down the path of the strobed/shutterglasses projection solution, but I'm certainly not ready to say that for sure until I do some hands on testing of some of these components myself.
In any case, this solution has real potential and some clear advantages over the other method.
Biggest advantage to the DLP shutterglasses route right now (for me) would be simply that I already have a working system in place pretty much "off-the-shelf," and without much fiddling. Certainly nice to have until I can get a better (but also more involved) system up and running to replace it, so I'm glad I tried it...but it probably won't satisfy me long term. An LCD solution will be the way to go instead, I do think.
Very glad you looked into this thread. Thanks again.
