Hey,

Last night I went to see Avatar in 3D at Albany, awesome!

I always thought that the 3D was done by flickering lenses where each eye would be 'blocked' in sync when the other eyes image was displayed, but the glasses did not seem to have any electronics nor did the lenses appear to flicker.

Can anyone enlighten me as to what technology is being used in the NZ cinemas for displaying the Digital 3D?

If they are RealD glasses then the lenses are just polarizing filters at different angles to each other. There is a unit which goes in front of the projecter that switches the polarization of each image projected so that the alternating images can only be seen through 1 lens of the glasses.

There are other technologies that use 2 projectors, I assume they work similar in that one projector is always polarized differently to the other.

Mike, they're Dolby 3D, which uses, I believe, circular polarisation. It makes the kit to project cheaper than RealD, but the glasses significantly more expensive.

tbnz, the technology you refer to is called active shutter.  It's what the 3D tvs coming out later this year will use as LCD panels are not capable of displaying polarised images (theoretically a DLP projector could, but noone seems to be going down that path - I believe as it's too expensive for consumer kit).  The Nvidia 3D vision glasses are active shutter as well.  You shouldn't see any flicker as the image is blocked around 60 times per second per eye.




I finally have fibre!  Had to leave the country to get it though.

The Nvidia set up isn't cheap either, you need to get a LCD monitor capable of 120hz refresh rate (60hz for each eye). (http://www.samsung.com/us/news/newsRead.do?news_seq=11954&page=1)
