3D vision hardware and requirements query
I am trying to get a 3D system set up to go with my workstation.
Perhaps I should point out immediately that I do not have anything to do with video gaming, either in their production or end use. I work in feature film VFX production.

Working in anaglyph mode is just painful on the eyes and I am hopeful I can get a decent and proper 3D viewing ability but am confused about a few hardware requirements for the 3D vision hardware and am hopeful someone well-informed in their full utilization can help me out :)

Firstly, if I understand correctly, the Nvidia 3D glasses are [u]battery operated[/u]. If I am wrong in this, please help me understand why the documentation alludes to them being so powered.
If they are indeed battery operated - then I indeed find this bewildering as any 3D feature which I have seen [Imax or otherwise] uses pretty basic polarized lenses and even in production, reviewing dailies with 3D projection, it was still just polarized lenses so just why glasses have to be battery operated and for what purpose confuses me no end. It seems odd to me that the glasses would not simply be polarized lenses only, which is what is used in viewing any stereoscopic feature.
Perhaps someone can explain to me what this if for, I am ever so curious to find out :)

Lastly, regarding 3D capable monitors- the only requirement mentioned is a display capable of a 120Hz refresh rate. Is that all? Is there not more to it than that?
Your approved display list is shockingly limited and to 22" displays as well -which is pretty small- especially for anyone accustomed to working on displays of much larger scale and resolution :)
I know of very high-end LED backlit LCD displays [one is 30"] that has a 168 Hz refresh rate, which seemingly fits the requirement.
However I would like to know just what other criteria makes a monitor acceptable for 3D display, if any. If all it takes is a minimum of 120 Hz, then there are far more display options out there to choose from compared to the shortlist of 2- 22" monitors, including monitors capable of excellent colour calibration procedures for optimum display :)
So again, if there is more to it than just a 120Hz refresh rate, perhaps someone can explain the remaining requirements :)

Thank you very much for any help!

You'll be wanting one of the Quadro graphics cards if you dont already have one - these are the only ones currently supporting 3d opengl which is something your production suites probably use. I couldnt tell you the min card for this though i'm sure someone else here will. ;)

These are active shutter based glasses that contain two big one pixel LCDs that switch on and off in sync to what is being displayed on screen via that USB ir transmitter you get with them. The benefit with this approach is that each eye gets its own full resolution of the image, whereas polarization splits it in half as both are already displayed and the passive glasses effectivley filter out for each eye. Of course the resolution might be different for the big cinema setups, but as far as the current polarized monitors available this is the case. If you've tried shutters before and find them to give you eyestrain/flicker too much, this is not the case with the 120hz glasses as each eye effectivly recieves a 60hz lcd picture

Its the 120hz [b]INPUT[/b] thats important! all these TVs advertising it as such are usually refering to the internal interpolation of the 60hz input they get in order to produce a smoother picture (particularly for sporting events!). Conventional connections do not have enough bandwidth for the full 1080p/120hz input. In the case of the monitors they use a dual dvi connector that comes with the monitor to achieve it. beyond the maxed 1080x1680 120hz dvi resolution we are talking HDMI 1.4/displayport, but i dont know when displays supporting this will arrive. You [i]can[/i] get 1080p 3d projectors, but all these do tricks to deliver half the resolution on each frame.

Next year we'll see TVs from Panasonic and Sony that are 1080p with doubled refresh rates over these, but you can guess these wont be cheap! ;) Asus is supposed to be bring a 24" 1080p monitor out at some point, but we've seen very little since the exhibition it was at.

Most of this is true, thought would add that in polerisation projector set ups, the resolution issue is genrally avoided by efectively using two projectors set to project on the same screen, and synced.

This does not matter for how the 3d is produced as you still need two pictures, whether using poleriastion, shutter glasses or even coloured glases (though in the last case the picture tends to be combined, this is why it suitable for all screens). I believe some polerised set ups still use a field sequential method and show pictures of alternating polarity.
