Has anyone who wears "normal" (ie. corrective) glasses been to one of these 3D showings? Does it work? Can you put the 3D-glasses on top of your normal ones?

Visually Avatar is probably the prettiest movie I've ever seen. Watched it in 3d and the only issues I could complain were the framerate and resolution. In high speed scenes you really can see the stuttering framerate which is pretty much horrible. Also due to low resolution (4k?) you miss some details. This is most easily noticeable in textures. Also the use of DOF was somewhat disturbing but overall it wasn't such big deal.

Sdw: I can confirm that! I had no problem with that last night!

Sdw i have low to medium myopia, slightly different in both eyes (-1.5 vs -3.5) and, as a result, mild strabismus. This causes loss of depth perception and making watching any sort of 3D movie (polarized glasses, colored lences) more or less pointless for me.

i'll let you do the homework on which other sceners worked on it :)

Gargaj: I cheated.. I knew this in advance.. but feel free to share your info on this subject :)

Welcome to the world of cinema.

pommak: in germany the usual resolution of digital cinema is only 2k, regardless if it's 2d or 3d projection. see this list of german cinemas

So from those of you who have seen Avatar. Should it be seen in 2 or 3D? or is it just a headache waiting?

3D ofcourse.. no headache... only WOW effects during the entire movie!

I saw the trailer to Avatar at the IMAX, but it just looked like an average 3d film. Good, but no better than Christmas Carol, Polar Express or even some of the documentaries they show there.

But I'm curious to hear if the full movie of Avatar is any more impressive than those films.

you can take magic's word for it... LOL

i saw it this friday - and i totally second iq. well 3d movie is great etc blabla, but what really kicked me where those beautiful images of the fluorescent forest. yep, made my weekend :)

i have seen avatar in 3d yesterday and i really liked it. i have seen ice age in 3d before but the depth effect was much better in the avatar movie. the only thing i didn't like so much was the visual character design of the native people. the animation and the forest are awesome though.

oh and no headache even though the movie is long

we need to start a new thread about virtual cameras
this thread was about some 1337 augmented reality in use for film making, but it has devolved almost into "LOL DANCES WITH SMURFS" nonsense

I hope I am the first and the last to mention Dances With Smurfs in this thread.

Just came back from the movies. Saw it in 3d. holy balls!!!

I haven't seen the movie yet but I've seen pictures of these glasses. They're not red-blue or lcd shutter glasses. What are these? Are they polarized glasses and left and right images have different polarizations? How can that work with light reflected off a movie screen? Anyone know how these work?

the projectors/screens are the same as always, there is nothing different than with normal televisions/monitors/projectors. You only need twice the refresh rate. You need of course your movie to produce twice the amount of frames per second too, with alternative left/right eye cameras.

The magic happens in the glasses, which alternatively make the right and left glasses opaque. There is an square wave signal sent to all the glasses in the room (usually thru an in infrared led emmiter like the remote controls) to synch the glasses to the framerate of the movie/demo. Glasses have a little battery that injects some current to the glasses to turn them opaque in the high or low values of the sqr wave.

So basically the projectors/screens/tv are regular projectors/screens.

The problem of cinema is that the 3d experience will be quite limited, as the left/right eye cameras are rendered acording to the position of the average cinema viewer, geometrically situated somewhere in the middle of an average theater room. In the PC and virtual reality setups, the rendering is done for the exact eye positions of the viewer, so real immersion is achieved (and looks really cool). So in 3D cinema is not immersive today, it just has some sort of "parallax" effect. But it's already nice, and they expect to make some extra money for a couple of years until everybody realizes you can simply buy a regular shutter glasses and have 3d movies at home in your regular TV/PC - assuming you have a relatively new one with synch signal plug in it to send the infrared signal to the glasses. For NVidia gfx cards, the plug is there and the emmiter is quite cheap.

That's what I know about the subject, so far.

ahh, so they are shutter glasses. I think you buy a pair when you go see the movie, think I'll go on monday

The glasses for the Avatar film are "circularly polarized" and manufactured by a company called RealD.

huh, circular polarization. That's interesting, I never even knew light could be polarized that way. Thanks

Thumb up for Avatar, nice 3D and great glow effects in the forest! :)
Actually I did almost get a demoscene vibe from some of the colorful stuff.

You can not say "for Avatar they use this or that technology", this depends on the cinema you are watching the movie. For more info have a look at wikipedia (where else did you expect to find some information? pouet?! ;-) or this pretty good german article from heise (sorry don't know a simlar page in english).
