On the rare occasion that I wear my optical glasses with my shutter ones, I usually wear the stereoscopic ones to the inside. This is only acceptable for persons who wear their glasses a little low on the bridge of their nose or are comfortable with wearing the shutter glasses high on the bridge. The effect is still well maintained in my opinion; although, my vision is not extensively impaired, so I cannot speak fully to that.

Cheerz for your quick reply, now I have no excuses for not doing this 3D thing - "Arh sweet surrender".

I would try to answer all of your questions for you but that would take all day. Then of course there would be even more questions. At this point all of the questions have been very basic ones and have been answered at stereo3d.com many times. Go there.
About the converter. My wireless i-art glasses have a button on the side of them that swaps the left and right eyes on the fly. Ytou might want to check them out. http://www.i-art.com.tw/

Just a thought for those of us with less than 20/20 vision, can any spectacle wearers comment on the results of glasses on glasses or is this a contact lenses only affair time?

I actually wear glasses and had them on for the entire review. The eDimensional glasses work great in conjunction with eyeglasses (mine anyway).

I wore my eyeglasses on the inside, and the eDimensional glasses on the outside BTW.

Thanks - I can feel the £'s demanding a recount before I order these 3D specs etc, just got to find a supplier this side of the pond.

Unfortunately, LCD projectors will not work. you need a DLP projector.

you can buy the glasses at www.eDimensional.com , there are authorized resellers on ebay too.

you can buy the inverter at www.3dflightsim.com

Thank You.
 
Excellent article, though there might be another way...

How about 2 DLP projectors, coupled to a dual-head card generating left/right images. Polarised filters can be used to polarise the light from each projector (eg vertical polarisation for left eye, horiz for right), and polarised glasses could be worn to filter the two overlaid images on the acreen for each individual eye. You would need to overlay the projection images carefully for best effect.

Advantages:
Better, possibly non-headache-inducing method, no flicker with the exception of DLPs standard rainbow effect.
Cheaper, lighter headgear.
"Stacked" projectors like this could also be used for a high-brightness standard screen by feeding the same image to both projectors and discarding the glasses.

Disadvantages:
Twice as expensive as the example in the article, because 2 projectors would be needed.
Do drivers exist for doing this yet? Again, the example in the article will probably have the edge here.
The two projection images need to be carefully overlaid for best effect.

Anyhow, just my 2c

Jas.
 
This is probably how it's done in the real theme parks - like the Terminator 3d experience at Universal Studios, which requires polarized glasses.

Might even work with LCDs... but the expense of 2 projectors, and the lack of drivers would be a problem.
 
Do Standard matte Screens with a 1.0 Gain Work Well for this or Should I look for something in the High Gain? 1.5+?
 
I don't know alot about screen specs, but the one used in the review had a gain of 1 and was fine.

The brighter the better with the glasses though, as I mentioned they do make the image appear darker. So a high-gain screen would probably be preferable.
 
I did some research a while back on the projection styles based on polarization. A couple things of note:
Most of the systems do use 2 projectors. I only saw one solution which used a single projector (similar concept to a triple LCD or triple-DMD DLP).
They require a special screen to maintain the light polarity. Otherwise the ghosting effect is absolutely awful.

There are now available dual projector rigs which do not use polarization or shutter glasses. They use a concept known as Wave Multpilex Imaging (WMI). The concept is that the RGB components are actually broken out into 2 slightly different yet distinct colours (e.g. Green and a slight variation of green, read and a slight variation of red, etc.). The lenses of the glasses worn only permit the light frequencies each eye is supposed to receive respectively. Neat concept, though I would imagine it would cause some slight colour distortion.
 
NOTE TO THOSE WISHING TO PURCHASE A PROJECTOR FOR 3D USE:

A fellow named Andrew Woods emailed me after the article was published, he's done extensive testing to see which projectors are stereoscopic compatible and wrote a paper on it. Apparently, there are a few that won't work even though the specs indicate they should.

Here's the paper:

http://www.cmst.curtin.edu.au/publicat/2007-05.pdf

The EP739 is approved on the list. Looks like they didn't try the IN34 though.
I'd probably go with the EP739 just to be safe...

Thanks for the Link.

Looks like the Biggest Problem is with the Color Wheel Speed. Most are measured at 60hz, 2x. The ones that work for 3D remain at 2x at 85hz+, some of the light engines drop the color wheel speed down to 1.5x at 85hz.

Looking at the light engines, the Optoma 739 has the TI .07 DDR DLP engine, the IN34 has the exact same engine. From a technical Standpoint, they should be the same, but I probably will play it safe.
 
Great article!

I've been an ATI fanboy for many years, but now I might have to reconsider the brand when I upgrade to DX10 in the near future...

I am a pilot, so I see "3D flight sim" every day, so the FPS would be my "killer apps". I guess people have tried it, so how was the 3D experience with scary games like Doom 3 or F.E.A.R.? Any dirty underwear anywhere, or did it not make them scarier?
