I found a place on the web that is selling the DepthQ projectors in 5 packs for $8665.00. I was just curious if anyone was interested in doing a bulk purchase? That would put the projector at $1733 each plus shipping or $1264 each plus shipping for a 10 pack. if anyone is interested let me know. Here is the link http://www.stereographics.com/products/Projector/index.html#pricing David | ||

Darn it I guess I should have looked at the add more closely, it was 10:30 at night after a long day. Thanks for setting me straight. It does let you know what kind of markup is on this 3d stuff though, a $500 each difference in price between buying 5 and buying 10 sets. | ||

actually dont be so hard on yrself it could be that the 10 pair comes with a more powerful emitter.. (this im only guessing tho) Cheers | ||

Does anyone see the price dropping on these over time much like other Infocus projectors have? | ||
| Alatar Rating: N/A |
Come on guys, it's not all that confusing... The offer is for a single DepthQ projector bundled with either five or ten sets of glasses. The prices are quite reasonable seen in that context. | ||
| Matt Rating: N/A |
12,640 for projector and glasses does indeed sound reasonable for commercial and business applications and folks who wipe with 100 dollar bills. I guess my question is this - seeing as models such as the Infocus X1 dropped significantly in price the past few years, would it be possible for this trend to continue with other products such as the DepthQ (yes, just the projector)? (sorry to hijack this thread BTW) | ||
| Anonymous Rating: N/A |
The pricing for the InFocus DepthQ projector is determined by the DepthQ marketing people, not by the InFocus company. Right now they have a unique product with no real competition, so don't expect a drop in the cost anytime soon. Buy the projector for $4000 and a pair of wireless eDimensional glasses for $50. The projector is worth the cost, the hyper-expensive "professional" glasses aren't. | ||
| 3dFan Rating: N/A |
I think it may be worth the cost when compared with other 3D systems but when I look at the super high definition projector I can buy for $4000 then I look at the DepthQ with it's 600X800 resolution and figure most of the time will be spent watching 2d movies anyway's the price starts looking worse again. I mean you can only watch Alien Adventure and Bloody Tease so many times. | ||

You're right in a way...The InFocus DepthQ has a Rolls-Royce 3-D engine in a Volkswagen body. If all you're going to do is drive it to the grocery store 99% of the time, the luxury price would be a waste of money. | ||

The problem with the Rolls-Royce theory is you can Buy the Rolls but the only thing available is wooden tires (crappy b movies) to put on it. This kind of ruins the luxury feel. | ||

In Focus DepthQ is primary used for 3D models visaulisation from CAD, molecualar or architectonic software - not for movies. So the content is not a problem. Another typical use is a preview of 3D movies witch will be later randered in higer resolution - artist check in this way their work. If you do not like low resolution - buy multiple DethQ and create a powerwall from a matrix of them: http://forum.gali-3d.com/viewtopic.php?t=28 | ||

Or use dual Dell 5100MP's (which are 1400x1050 @ 3300 lumens) in a passive configuration. We have two of these stations now with excellent results. Interestingly, we find we can run these quite happily with a $100 GeForce 6600 card set in vertical span mode. Both fully uncompressed stereo (24 fps @ 1400x1050) and WMV9 (24fps @ 1400x1000) work beautifully. | ||

I'm digging the dual Dell passive idea. It seems more justifiable to purchase 2 high quality projectors for a passive setup rather than 1 system for the same price... for us 3-D moviegoers anyway. However, it seems passive displays get a bad reputation for ghosting. Is this true? | ||
| Anonymous Rating: N/A |
Hey 3dfan, do the math! If you link multiple projectors so that each projector displays only a portion of an image, and combine all the partial image areas into a single complete image, then the total image has a higher resolution than each individual projector. Duh! | ||
| Charles Rating: N/A |
Matt: If all parts of your passive system are high quality (professional screen material, filters and glasses with circular polarization, etc.), you should be able to keep ghosting to a very low level. However, you can't just buy good projectors and try to skimp on everything else. | ||

Hey Guys, I am looking to make a passive projection setup, I have a sanyo plv-z2 LCD projector with a native resolution of 1280x720p maximum resolution of 1280x1024. I am looking to buy another identical projector and then run it in passive projection setup. My projector only has dvi in and s-video in. I am looking to use this with circular polirazation glasses, and to play PC games and 3D movies on it. Does anyone have any experience and also as this thread has a lot of technically minded people i hope you can please answer a load of questions that i have below: With this dual lcd setup i would need a silver screen, do you know if i can make a DIY silver screen and how do i do it? sorry for all the questions but do you also know if my projector will defintely work as if i go ahead i will need to buy another LCD projector identical to my one for it to work and i don't want to find after i buy it that it does not work. i have only a dvi in, on my projector would i need to use a vga adapter? do you know of any more sites that go into detail about passive lcd projector setups? With passive lcd projection, do you use linear or circular polarized glasses or both? Is there a large amount of 3d films on the market that has the correct format for passive lcd projection? I heard it's in the hundreds is that true? Okay sorry last question with passive lcd projection can you play frame sequential 3d movies, page flipped, over and under, side by side, sync doubled, like all of the formats out there? sorry for all the questions but am really intrigued by all this stereoscopic 3d goodness and would love to have all my questions answered as i am really looking to buy into another projector or even get a second hand one. any help much appreciated many many thanks | ||

I have checked some projectors (LCD and DLP) for 3d stereo and are 2 major problems with 1280x720 projectors 1.no VGA input (this can by problematic for use with cheaper (no bad product!) shutterglasses from e-dimensional and pageflipping 1 projector active 3d stereo projection. 2.1280x720 projectors are videoprojectors primary used for movies and the light output (ANSI) is low for both active and passive stereo). 3.refresh of LCD is maximally 60-62 Hz.No good for pageflipping active stereo. For movies,games simulators etc. is I think the best way active DLP projection with dataprojector with high ANSI output and shutterglasses. No special screen, no filters,no ghosting, no problems by head tilting,only 1 projector bulb in action, this all is more cheaper and the picture better.Flicker absolutly minimally - 86Hz refresh(I have DLP active system in my home). For 2D movies is LCD better (mayby)- better black and absolutly no rainbow efect.(My DLP had by 86Hz refresh no rainbow and I are rainbow sensitive). Qestion is - is for home usage passive system good? | ||
| Tony Rating: N/A |
Hi hornet, thanks for the reply, i know that my projector would have a low refresh rate of 60hz but if i get another one projector and connect it up in passive mode i could have 120hz refresh rate which is just like the infocus depthq 3d projector which has 120hz refresh rate. Also i am not looking to use e dimensional glasses, instead i am looking to use circular polarized glasses which are like the ones used in imax theatres, they don't need to sync like the edimensional shutterglasses. Also i will probably be projecting at 1280x1024 resolution which is my projectors maximum resolution and i will use powerstrip so i can setup a ini driver so as to get the highest refresh rate that my projector can do and i am also looking to get a silver screen to project onto. So surely this should work very well should'nt it? Also i won't be doing page flipping as i will be doing passive stereo. And there should be no ghosting in circular polarized setups when you have 120hz above as in this setup. The reason i want lcd projection is that at this show i was at they were using 2 LCD projectors in a passive mode and i was blown away by the effect but unfortunately there projectors combined costs 18,000 dollars. They said to me i should be able to set this up by getting myself another projector. But they didn't go into detail which is why i am asking you guys here. any help much appreciated many many thanks | ||

You can use either linear or circular polarization, but not both. Linear has less ghosting but circular doesn't degrade when you tilt your head. Re. 1280x768 vs. 1280x1024: the only thing that matters is your projector's native resolution. Use anything else and it is simply resizing (= lost quality) before presenting the image. Refresh rate is a non-issue in passive systems; each eye is seeing every frame output by its projector, so flicker is at exactly the same level as it would be if you used the projector 2D. | ||

Hi Alatar, So you suggest it's best for me to use my projectors native resolution of 1280x720p. That's good to play PC games that support resolutions for 1280x720. But if i want to play a 3d movie like the ones you can buy all over the net, then will it still look good, as the 3d movies are released on dvd's and the resolution of dvd's are upto 720x480 would this still work on the projector setup that i have mentioned? Also do you know if was going to get a second identical projector to the one i alrady have if it will definetely work? I was hoping to feed the signal only through dvi to keep a very high video quality. Do i need a stereo converter like the one by christie projectors. They have one that takes 2 dvi signals but these are more for professional use rather than home use, so they may cost in the thousands of dollars do i really need to get a converter as i thought the PC does it all for you. So i would need help on this one? Also is there a way i can do a test to see if my current projector may work for a passive setup? Last thing, do i need one of those passive projection stands or towers, or can i just stack one projector on top of the other? any help much appreciated many thanks | ||

I believe that I explained how to test your existing projector to see if it will be suitable in your other thread on the subject. DVD movies are a much lower resolution anyway, so it shouldn't really matter which resolution you use. It depends on how you are playing them back. One good way to play 3D content is Peter Wimmer's Stereo Player, you can get a good idea of what this will look like right now by setting up your computer for 3D output but only attaching one projector (i.e. your existing one). This will force you to work through all the problems *before* you spend a lot of money on another projector. You can attach the other eye's video output to (e.g.) an old monitor. Once you have one eye working properly, set up the polarizing filter and glasses and ensure one eye can see normal playback and the other sees only black. This will be roughly your final output quality, but you will see it in only one eye. If you want to be double-sure, then exchange the projector and the old CRT, switch polarizers and be sure only the other eye sees the image. | ||

Hi, I have readed more more about 3D stereo in last months and will in November purchasing 2 projectors for passive 3D stereo system . After testing of active projection with DLP (this were so good!) I have converted to active projection.The result ist excelent (this is true) 1024x768 (native) resolution and practically no flicker, no ghosting, no expensive screen (system is mobile).More more cheaper and simplier and the result is very good. The price of this DLP is aprox 1000-1200 EUR (Benq PB 6240),e-glasses cca 70 EUR, and PC with NV Gcard. More cheaper and result the same or better. Think about this. I not projector dealer, :-). | ||

| 3dFan Rating: N/A |
Someone correct me if I am wrong but in an active syetem if the timing of the shutterglasses is off or if the shutterglasses don't go fully dark then ghosting occurs. In a passive system the light is polarized and sent only to each eye so as long as the projectors are properly aligned there can be no ghosting. So why the talk about ghosting on a passive system? | ||
| Hornet Rating: N/A |
Ghosting in passive systems had 3 reasons 1.The polarising filters are not ideal (restlight) 2.The non depolarising (expensive)screen is no ideal. 3.By using of linear polarisation filter system the ghosting increase with tilting of head. In praxis all the 3 factors summarises=little or more ghosting. The timing in active systems can by problematic, from my experience with DLP XGA projection and shutterglasses at 86 Hz refresh, this is absolutly no problem, picture is more better as CRT! The best way is self testing of configuration DLP XGA projector and shutterglasses and I thing you will forgot passive system, of course. | ||
| Alatar Rating: N/A |
Yes, in general passive has more ghosting than active. A third type of system, called "hybrid" gives the best ghosting performance of all but is very expensive. | ||
| Bill Rating: N/A |
Tony, you really need to check whether or not your LCD projector will properly polarize (e.g. test it like Alatar suggested or get a second loaner projector to see whether it works). Passive DLP projector systems should always work, but LCDs are already polarized and using them for 3D might or might not work (i.e. it depends on how your projector is polarized; to find out, there is no other way than to test). I have a dual DLP passive system and found linear polarizers better than circular, because ghosting is by far not as severe as with circular polarizers, and unless you fall asleep your head will be straight when watching a movie anyway. I would also strongly recommend a stand for the 2 projectors, because you need to align the images as closely as possible. If you just put the projectors next to each other, the smallest vibration will bring them out of alignment, and you might have more problems with keystone adjustments. | ||

3dfan: The ONLY 100% ghost-free stereoscopic viewing method is a setup that totally separates the left and right images so that it is physically impossible for either eye to see any part of the wrong image (for example the z800 and similar HUDs). With CRT images, ghosting is unavoidable because of phosphor lag in the screen images. There is no way to prevent this ghosting with current generation CRTs. ALL superimposed projected stereoscopic images viewed with active or passive glasses have the potential for ghosting because of imperfections in the glasses. Projected images using either two projectors or an active properly synched DLP projector have no inherent ghosting in the overlapping images, and you can see ghost-free images IF YOU ALWAYS FACE THE SCREEN DIRECTLY. Head tilting with linear polarized glasses and head turning with shutter glasses will allow ghosts to leak through the lenses. (If you can keep your head reasonably still, either projection method should keep the ghosting down to around 1% -- about as close to perfection as you'll get with presently available equipment.) I personally recommend the InFocus DepthQ projector if you can afford it, because it works "out of the box" with no real setup, and works anywhere with cheap glasses and a wall for a screen. If you want higher resolution AND IF you have a permanent location to set up and align two projectors AND IF you have the proper filters and a decent silver screen,AND have the time to repeatedly set things up each time you move the projectors, then you can also get good results with a passive setup. The choice is between high price, ease of setup, and convenience, or a bit lower price and setup hassles. | ||

Tony, I personally in your situation were tested DLP active projection with normal XGA dataprojector with high ANSI (the costs is price of the shutterglasses) and PC with Nvidia card. I thing after this your were not thinking about passive system. The LCD Sanyo is wery good for 2D, I were used this for 2D (or e bay?)and problem is cheap and simple resolved. I have this problems before months and I totally satisfied with my active XGA system. Other way is DephQ, the resolution is more lover, for my this was unaccetable, with good dataprojector the flicker at 85 Hz is absolutly minimal, and price is cca 35% of DephQ. | ||
| Alatar Rating: N/A |
M.H. : one you left out is "hybrid" (active plus an additional polarizing layer), which essentially combines the benefits (and costs) of both active and passive. The trick here is that because the active glasses already provide polarization on the glasses side, you only need one additional layer on the projector side to make it work (and thus have the light loss of three layers compared to two for active or passive alone). The result is quite incredible -- you cannot see any ghosting at all, even in the highest contrast scenes -- but of course you have all the costs of both (dual projectors, polarization-retentive screen, expensive glasses etc). | ||
| M.H. Rating: N/A |
Alatar: do you speak about active projector + Z-screen ? Yes I had foregt this. It is on the normal polarization proejction level acroding ghosting .... | ||
| Alatar Rating: N/A |
No, actually I was referring to dual projectors with a polarizing filter on each one, combined with active glasses with the fixed (i.e. non-liquid) layer of each eye perpendicular to the other. The extinction is far better than either active or passive because each eye is filtered twice (i.e. goes through three aligned polarized layers rather than two). Also, tilting your head results in a black image rather than a ghosted one. It is prohibitively expensive (in $ and in light loss) for most practical applications, but it does offer excellent freedom from crosstalk. | ||
| Alatar Rating: N/A |
Added: just to clarify, the dual projectors have to be set up to display alternately, of course. Thus the right eye can't see the left-eye image both because the fixed polarizers are at right angles to each other *and also* because when the liquid layer of the right eye glasses is open (i.e. aligned) the left eye projector is off. | ||
| Charles Rating: N/A |
Alatar: Have you acutally seen a demonstration of the "hybrid" setup you describe, or are you speaking of a theoretical system? Is there any PRACTICAL situation which would justify the expense, completexity of setup, and maintenance (very high intensity lamps x 2, huge cooling system for both bulbs, etc.) for the small improvement in ghosting? Reducing ghosting to 0% from 1% (currently achievable with a good passive circular polarization system) sounds like a bigger deal in theory than it is in actual viewing. Most people won't notice the difference. | ||
| Charles Rating: N/A |
Alatar: On the other hand, from a theoretical standpoint, wouldn't you get the same result with an active Zscreen projector (which puts out polarized light and also only displays one image at a time) by using LC shutter glasses with polarized filters over the LC glasses? Then the only practical problem would be light loss from the single projector bulb. | ||
| Alatar Rating: N/A |
To take your questions in order: Yes, I have seen this approach used, not only in demonstrations but also in commercial daily use. Yes. Consider if you already have a dual (film) projector system set up to run in active mode (you use two projectors because, for reasons I explained in another thread, single-projector frame-sequential is not neccessarily the best way to go when you are dealing with film). Now you discover that your customers have no problem with brightness but find the ghosting and head-tilt issues problematic. So, since you have cleverly designed your shutter-glasses to have perpendicular polarizations (and your screen material is reflective anyway), you simply slap a polarizer in front of each projector and bingo, your ghosting problem is solved, at the expense of some brightness. Not that this is the way it really happened (you just asked for a possible scenario), but consider that if you are trying to interest a theater in a new system, bandying about terms like "advanced new hybrid polarization system" probably doesn't hurt your sales. I am not proposing that I or anyone else here would want to do this these days, the additional cost -- especially in a digital world -- almost certainly outweighs the achieved improvement. But I did want to point out the perhaps rather pedantic point that Michael's list was missing the very best technique for reducing crosstalk. Perhaps, since we agree that hybrid isn't practical for these purposes, the point is moot and I am guilty of needlessly confusing the issue. The z-screen would certainly work, although I wonder if the fact that you were using the same (Liquid Crystal) approach for both layers would result in a lessening of the effect. Of course, it only works for single-projector active setups. Thus perhaps they are really two different "hybrid" variants. | ||
| Alatar Rating: N/A |
On thing I didn't notice until re-reading your post: you say "by using LC shutter glasses with polarized filters over the LC glasses" but in fact you shouldn't need any additional filter as the shutter-glasses consist of a fixed polarized layer plus a LC layer that changes polarization back and forth. So all you need is to be sure that the panels in the glasses are mounted in such a way that the fixed layers are perpendicular to each other. | ||
| Charles Rating: N/A |
Alatar: "So all you need is to be sure that the panels in the glasses are mounted in such a way that the fixed layers are perpendicular to each other." The problem is, they AREN'T -- every brand of commercially available LC shutter glasses that I've ever seen has both lenses mounted identically, so the polarization in both eyes is the same. | ||

Hey Guys, With all this dual projection talk, if i was to setup a passive projection with dual projectors will i get an amazing pop out of the screen effect that simply where the 3d comes right out and nearly touches me? Will this setup be better than having the infocus depthq. I saw this at a show and did not think much of the depthq the 3d would only pop out about a foot from where it was projecting, where as a $18,000 dual passive projection setup the experience was like imax. The images floating out and nearly touched me, that's what i am looking for in a home projection setup. Would i get that kind of experience on the cheap using my sanyo plv-z2 LCD projector x2? Or does it all depeend on the brightness? Do i need a dual head graphics card to run sterescopic movies and games to my dual projection setup? Do i need a active to passive stereo converter or is it that having the dual head graphics card eliminates the need for having a converter box? If i only need a dual head graphics card then what settings should i use in the nvidia drivers? Is it split node mode or dual mode? (i think i got those names right) I have browsed the net for these converter boxes and really can't afford them as they come in the thousands of dollars. I really want to my plug my laptop to the dual head projector but i only have one dvi out coming from my laptop. So are those converters only for laptops? Is there a way i can do dual head projection with a laptop? well if you could please anwer my questions i would be very grateful. many thans Tony | ||

Charles: at least some batches the original Imax headset design and (I believe) all the enhanced "PSE" Imax glasses work the way I describe. We recently bought a batch of 200 pair of the original series from a developer who had bought out the inventory of a theater that closed down, so there certainly are some available out there. Tony: the depth you perceive, as long as the system is working propely, is related to content and projection geometry, not the technology used to create two views. Brightness is important but not vital (you can always darken the room instead). Proper stereo setup and geometry is vital for extended viewing periods. You need dual head if you use dual projectors (unless go with a converter box, which is silly as it is cheaper to buy a new computer). We use nVidia cards in horizontal span mode for movie playback, but you will need to use other modes for games etc. It's hard to do dual-projector stereo with a laptop; you really need two video outputs that match (i.e. dual head). | ||

Alatar: What you have written is very interesting news. Did the original 3-D IMAX theaters go to all that expense to combine polarization and active image separation, with the entire system correctly set up for both? If so, it apparently was too costly, and IMAX has come a long way downhill from that peak. The last 3-D IMAX movie I saw used a terrible Infitec process, with obvious color distortions and bad ghosting. I have searched on the Internet for the old theatrical IMAX shutter glasses and never found any. Are you willing to sell one pair from the large batch you just purchased? Also, will those glasses work with a StereoGraphics IR emitter, or is a specific proprietary emitter required? | ||

Imax certainly didn't use the technology in the early years, and I don't know how many theaters they ultimately equipped this way. I'm told that they've given up with shutter glasses altogether for quite a while now, more because of cost, maintenance and theft issues with the glasses than with the technology itself. I remember you mentioned seeing an Imax show using Infitec and I spoke the relevant gurus at Imax about it specifically. At that time they told me quite categorically that they hadn't done any public tests at all, so I'm quite confused on the subject. I will ask the powers that be about a selling pair of glasses but it's hard to believe there will be any enthusiasm for it. The bureaucracy is so pervasive that just getting permission to sell them would cost ten times anything you might pay. In any case the IR signal is proprietary so that would be an additional obstacle. M.H.: thank you, I do appreciate your offer, but we have quite a stock of them at the moment. We also have access of course to very high power ones when required. In any case, as I said, thank you for the offer. | ||

Alatar: Back in August 2005 I posted an entry in the forum "News on IMAX vs. InThree Lawsuit" stating that I had seen the IMAX movie "Aliens of the Deep" in April 2005 at the Virgina Marine Science Museum's theater using a pair of slightly color tinted passive glasses which I had assumed were color-coded anaglyph format. Several people, including you, suggested that the theater had more likely been using Infitec glasses, a technique that I confess I was unfamiliar with at the time. Those postings are still on this website if you'd like to review them. If you can get permission to sell me a pair of the IMAX glasses at a more or less reasonable price (I'm not Bill Gates), I'd appreciate it. I'll worry about the proprietary IR emitter later.

Hi Tony, I months ago I have tested Panasonic XGA LCD projector for passive setup (I will build home passive system), the great problem is internal polarisation of LCD panels, the panels for the 3 colors are different polarised! (for color contrast enhancement)and this can by wery problematic for passive system with LCD projectors - I think normally LCD videoprojectors are not usable for passive system. Test active 3D stereo with DLP projector(normal dataprojector with VGA input, and shutterglasses, for gaming and simulators this is the cheapest way for satisfaction, of course. | ||
