You spend hundreds of dollars on shutter glasses so that you don't have to spend thousands more for the TV in order to get the equivalent picture quality for polarised glasses.

It is not the same at all.
Home theater equipped with dual projector, silver screen and passive glasses outperforms any theater system including IMAX.
Most of all, theater screen size is not compatible with stereo content and always shows gigantic exaggerated scenes and actor sizes.

Yes - they are the same. They are both true stereoscopic full color 3D

LOL! As opposed to totally diminished in size scenery and actor sizes.

I guess you are not familiar with human stereoscopic vision geometry.

'True stereoscopic' is a meaningless statement.

As opposed to Anaglyph or ColorCode 3D. If my description doesn't please you . . .

It is irrelevant to projection method.
The fact still remains that screen sizes of home theater will
display 3D actors lot closer to his/her real size.
But for regular movie theater screen size it will always be
excessive size due to gimmick content that is parallax limit driven.

Well - you could say the same thing about normal movies shown in a theater.

Yes,
the most of adrenaline from movies is related to abnormal size of actors. And IMAX is the top score.

You know that 3D content thread we made that's stickied? Are you saying that if they make movies like that it will be incompatible with theaters and big screens and imax?
And if they are will they still look good or worse than they currently do if they follow our advice in that thread?

To make a cinema theater realistic and undistorted projection of 48 inch screen content, the movie projector in the theater must float the stereo window from the screen size to 48 inch stereo window size
and then movie spectators will see the same as if they ware sitting in front of their homes theater screens.
Floating is the technique for matching screen size to the content's stereo window size in order to satisfy geometry requirements for realistic content projection.

If this has been addressed elsewhere forgive me for asking again.
Is 3D going to have a "FORMAT WAR" like Beta/VHS or BLURAY/HD? If so I will wait untill there is a winner. I lost on both of the other wars by buying BETA and HD.
Thanks.

What different formats do you think there are?

Just asking. Will all 3D discs play on any player?

3D Blu-ray discs will play in any 3D Blu-ray player.

No,
the war is over now and the only format is 3D Blue Ray
and the player does not support any other 3D formats.

So, if you want to play legacy format on DVD like the field sequential DVDs you need to use legacy equipment.

Alternatively you can convert legacy 3D DVDs into 3D HD Frame Compatible format and play is using 3D Blu Ray Players. It requires manual selection of 3D mode on your 3D TV.

So is there talk about a unified system for viewing? in otherwords, will it come down to all manufacturers producing 3D displays using the same Technology?

Isn't there technology being tested for holographic TV's coming? The Television program "The Biggest Loser" and some concerts have used this holographic technology already.... How long of wait for that?

Or is that like asking how long until flying cars are put into production?

Be careful with holographic displays, many people are fooled very easily, they see a picture in mid-air reflected on a semi transparent glass and they believe they see holograms.

The best Holographic display currently demonstrated is monochrome, small, ultra low resolution extremely slow (1 frame every 2 seconds) and are laboratory prototypes that cost would cost millions on the market.
Saying an approximative release date for holographic displays would be like reading a crystal ball. Usually people say "at least 15-20 years" to look less dumb when asked that question.
What's more, recording a holographic picture is horribly complicated and extremely impractical. Recording stereo video for current 3-D is a piece of cake in comparison, it works almost like 2D with small differences. I have a tendency to consider Holography as a completely different medium, it's like comparing a painting (TV/cinema/2D/stereo3D) and a sculpture (holographic display).

Why - does that exist with HDTVs? Don't we have PDPs, LCDs and DLP RPTV to say nothing of FPTVs. And we have multiple HD resolutions; 1080P, 1080i and 720P

Currently, 3DTVs use active shutter glasses and frame sequential 3D. There is another method which is in use, circular polarized passive glasses (super cheap) and Xpol tech. for 3D LCDs. This is not yet available here in the USA but is available in the UK and Japan (first launched). The panels are more costly and do not display full HD per eye (max res is 1920x540) but the glasses cost dissappears.

Latest estimate is 20 years.

Hi Lee:
Thanks for the detailed and interesting illustrations.

*Would you where I may look for enthusiastic & technical individuals to do 3D software?

I am looking for Software developers who might work on Stereoscopic 3D Web Player, especially for the following Display mode:

No Glasses/Free Viewing
3D Display formats:
1. Cross-eyed
2. Parallel
3. Mirror Split
4. Left (2D)
5. Right (2D)

This is much like what YouTube has in their 3D channel, but they still can't support direct stereoscopic viewing for Nvidia 3D Vision.

*I wonder if there are successful add-on or plug-in tools had been developed to the Nvidia system.

I don't own a 3D TV, but a common complaint that I hear is that you HAVE to use the 3D for 3D content. Am I wrong in assuming that you can turn the feature off? It seems like a pretty stupid idea, so I'd have to assume that the manufacturers would think so too.

A 3DTV is an HDTV. Most of the 3DTVs have a 2D to 3D conversion on the fly feature that allows you to watch 2D content in 3D. The results are a mixed bag leaning towards meh. If you don't want to use the feature, you don't turn it on. Same as other features like DNR or Sports Mode, etc.

good stuff here...forgive if this has already been talked about(i'm a bad skimmer).

i have an onkyo TX-NR905 it only has 1.3 hdmi's. will i lose any 3D (or anything else) by going through the onkyo instead of going straight to the tv? the tv is a 3D 240Hz tv.

just think of 3D as an extra bell and whistle on a great tv. 2D looks great on them too.

my confusion is that i think i understand that 3D doesn't require a 1.4HDMI so why would i lose anything going through my onkyo that is 1.3HDMI???
