Cinema 3D glasses - Different to home ones?

So I know there are two standards with regards home 3D.
I have a Samsung 3D TV, so mine is active (arguably better 3D - but the glasses cost oh so much more).
Then there is the "passive" standard used by the likes of LG.

In the cinema we have "Real3D". Is this the same as the passive 3D used at home? So would the glasses be compatible?
Or is this a sneaky "3rd standard"?

Cheers.
 
I believe that the cinema 3D is different to TV 3D - something to do with how the images are positioned?

I can't remember tbh

How about you try and let us all know if the cinema glasses work? :rolleyes: :p
 
Well 3d in the cinema use just standard 3d glasses, to render the illusion of 2 different depths.

While at home, do they not use similar shutter technology to nVidia?
 
As a stereoscopic expert (or at least I was a year ago when I worked on a film) the passive glasses used on home TVs and the Real3D ones in the cinema are exactly the same.

And yes the active glasses give a better picture quality.

And no there are not "two" different depths Gibbo, unless the stereo was chosen to be that way. Real depth and drop offs are faked. What you probably mean is that 2 different images are displayed at the same time, and one goes to each eye, tricking the brain into seeing depth.
 
you can buy either the normal 3d glasses which are same as cinema or get the battery ones which are different.. i didnt notice much different between the cinema and the normal tv ones
 
Thanks for all the replies.
It does appear that not everybody is aware that there are two standards for home 3D - Active and Passive.
Not all home 3D setup's have the "flickering shutters" - that is active and found on Samsung for example. There are just as many passive home setup devices which don't have the shutters.

What I'd read (from a site I cannot tell is reliable or not) is to do with Polarisation.
Apparently on the home passive setup both lenses were polarised the same (horizontal I believe) however with the Cinema "Real3D" one lenses has horizontal polarisation and the other vertical.
So making the home passive glasses different to the cinema "Real3D" passive glasses.

I don't have any home passive glasses to try in the cinema and my active ones will not work as they use the different standard.

What would be the point in having both lenses polarised the same way? That way both eyes would see the same image. The way that passive sets work is that each eye sees a different image, because the lenses are polarised in different planes.

I can't imagine that glasses for home passive sets and cinema projectors work differently: they will both consist of two lenses polarised orthogonally.
