3d Glasses and monitors - anyone tried them?

(and maybe head tracking too :)

Yesso: Alternating between two reflections very quickly (at say 60 Hz) does help create the illusion of reflective materials. But it's also pretty distracting. But it does help. But it's not really enough.

bump. anyone know if it's possible to code anything in opengl or similar that works with reald.com's cinema glasses?
I have a 3DVision setup here, some demos look great with it - thought about making a "3DVision compatibility list" at some point but i suppose the audience isnt that big for it :)

I've had a 22" 3D vision setup for quite some time now, that is also a tr-22" 2D surround setup.
Both are awesome, but since the support for 3D in games was far from perfect, I'd say love my 5040*1080 best.
Just Cause 2 is just so f... awesome that way, spent so so many many nights wandering in Panau.
Also if you're into it, FSX is phenomenal.
And BFBC2.
But for 3D, I guess for older games theres always something that makes it not perfect.
For newer games this should change.
But there remains some king of white ghosting and the loss of brightness.
However it's still a great achievement.
i know one can easily do anaglyph rendering by displacing the color channels. however, what about these reald/3d glasses? when looking in the cinema it seems as if it's two images rendering at displaced offset - but with the same color set. is that by interlacing somehow or what's the trick? :)
Colorseparated 3D uses the different wavelengths of the light to produce an image from two different viewpoints where "modern" 3D movies and games uses polarization. Images are created/captured with two cameras running at either horizontal or vertical polarization. I guess the easieast way to explain it would be to see your 3D glasses as mail-slids where left eye is horizontal, allowing only wide packages to enter and your right is vertical allowing only tall packages to enter.

On a 200hrz refreshrate, each eye would only have a refresh rate of 100hrz, usually quite enough to prevent flickering. Every frame, the polarizations shifts from horizontal to vertical and so on. There's also something called circular polarization described with a simple anymation here to illustrate how 3D glasses interpret the varying polarization.

I've just bought a LG 3d monitor and am well pleased! It's a much cheaper option than the 3d vision and less of a drain on your hardware.

Some of the games, such as Modern Warfare 2 and Assassins Creed 2 look incredible. I'm using Tridef to convert Direct x stuff to 3d, which works great on some demos, but only a limited selection unfortunately as it doesn't support Opengl.

I'd definitely like to see more 3d support in future demos.

Wade: Not as simple as you would think, sadly. For some demos, the whole rendering path just doesn't allow it. (Which is why some demos are completely flat, like most raymarch-y stuff.) Also, I don't know if you can "configure" Tridef though. We use NVIDIA's 3DVision and there's an API for that which you WILL need if 3D works but you need to edit your convergence, etc.

I recommend trying this - with proper settings (in my case depth separation turned all the way down), it's massive.

seeing as we're reviving dead threads,


So let me get this straight... instead of making a CG set and use cheap and quick green-screening or whatever to add it in afterwards, you make the same CG set but spend some extra time and money making it realtime, project it somehow onto a background wall, spend even more time and money getting the colour and light just right so it blends in, and use head tracking stuff on the camera.

I can just see 3 small catches here: 1. It'd cost more, 2. It'd take longer, 3. It'd look worse.

yeah. more demos with L/R z-offset please :)

smash just explained why the demoscene is dead, only using slightly different terminology :)

I need a new monitor. It'll be mostly (like 95%+) used for coding or graphics work, so I'm mostly looking for high resolution and comfortable viewing but 3d for demos is kind of tempting. Is it worth considering?

And if it is worth considering, is it possible to kkapture demos in 3d (where they work in 3d at least)?

Gargaj: Thanks for the recommendation! It worked with the generic Tridef profile. Although nothing jumped out of the screen, it was really superb! Actually, a few of the Fairlight demos have been very good in 3d, though the newer ones are a bit too taxing on my PC.

Smash: Fucking hell, that link was amazing! I can't wait to see where this goes.

Psonice: I'm not finding many demos work in 3d at the moment, but I suppose you could capture them to a video file and run the 2d to 3d conversion in some of the video players. It's not true 3d, but it gives it a bit more depth.

As said, I watched a lot of them with 3D so I can make a 3DVision compatibility site. (Maybe perhaps include some tips on how to tweak some of them to work correctly.)

That would be awesome! It's been a bit hit and miss for me at the moment, not knowing which demos will work and which won't. And I believe most things that work with 3d vision should work with Tridef too...and maybe other programs like IZ3d.

youtube supports 3d btw. If we can find a way to capture in 3d, this would be good :)

>Psionce - 3D monitors are 120Hz are they not?

Just been playing with a Toshiba laptop that has 3D glasses, I was impressed, watched Avatar, good (tweakable) depth, nice, but needs to be bigger than 17" though...

I guess my question really is "are they good for general work use too?" No point buying a screen that's good for the occasional demo if I spend 95% of the time working on it and wishing I'd got something else :D

wade: btw, we added 3dvision support to uncovering static (i.e. with gargaj's help and the nv api we set the settings appropriately) - so if you run it with 3d vision you should get a decent (but slow :) ) experience out of the box. i guess that's something we'll try and do generally from now on.

psonice: yep, im in the same boat as you. i want a 2nd monitor for home, and id like to know which 3d ones are a) good enough at 3d to be worthwhile and b) good enough at being a monitor to be a 2nd monitor to know if i can go 3d. :)

My colleague uses 2 Acer GD245HD's and they are pretty decent at both being a monitor and being 3D.
Psonice/Smash: A couple of things bothered me to begin with. The monitor seems very bright as standard. When it goes into "3d mode" (usually does this automatically when you play a movie or game) it's like staring at the sun...well, not literally, but it's very bright to compensate for the dark glasses.

That said, you just turn off the 3d mode when you're done viewing in 3d and with brightness dialed right down in standard mode it's perfect.

The other thing that bothered me is that you see very faint scanlines. Nothing drastic, but it's just noticeable compared to a standard monitor. However, I've only had the monitor 2 weeks and I've got used to it. I it quite comfortably as my main PC monitor, even for Photoshop.

This is the monitor I have btw: http://www.ebuyer.com/270573-free-game-lg-d2342p-pn-lcd-tft-3d-ready-23-hdmi-mon itor-d2342p-pn

Considering it's so cheap it's really impressive and a lot cheaper than going for a 120hz monitor plus 3d vision glasses. You have to experiment a little with some of the settings and how far from the screen to sit before you get the best effect, but when you find that sweet spot it's amazing! Playing Modern Warfare and Left 4 Dead has got my adrenaline racing at times.

Smash: That's awesome you will be supporting 3d. Unfortunately Uncovering Static is less than 1fps on my system in 3d, but maybe someone with a powerful machine could do a youtube 3d capture at some point.

I got a number of Fairlight demos working in Tridef. Frameranger was especially cool!

One thing that can be bothersome is that sometimes you get ghosting if the monitor matrix isn't fast enough to switch between the two pictures, usually when there's a large contrast difference. This was somewhat bothersome to figure out because I thought it was a code bug, but our NVIDIA contact confirmed that it's the monitor.

wade: it's even electron wave free! :D

I still can't decide what to do. A screen like that is probably ok, and it's cheap, plus demos in 3d has me licking my lips. On the other hand I could spend a bit more cash and get a really high res 27" screen which I guess is going to be a bit more productive.

Image Contrast Ratio: 5000000:1

Either it's black is really really really dark or it's white can light planets.
