Funny you should mention that, because I had to import the 3D blu-ray from the UK - they didn't sell it in the US!If you’ve noticed Big Hero 6
That's interesting, because the Hobbit 3D blu-ray looked horrible to me, until I turned on my TV's motion smoother (which effectively doubled what I presume was a 24 Hz version to 48 Hz per eye).This is what Peter Jackson was attempting to do with filming and displaying The Hobbit at 48fps. Unfortunately for Jackson, a lot of people didn’t like the “non-traditional” look of high frame rates.
This "accommodation" problem is one of the bigger issues with current AR tech. It's why AR is probably the killer app, for lightfields. That's why so many are excited about Magic Leap finally launching, this year.Light fields can also fix some of 3D’s other problems already mentioned, but tackling this particular issue is where light fields truly shines.
The way I describe it is that each pixel needs to be able to simultaneously appear as a different color from different directions.The problem that crops up here is that each lens needs to have its own special image, or array of pixels, displayed for it to work correctly, and each lens equates to a single pixel of a normal, non-light field image.
Definitely not the same problem as VR movies, which usually make the mistake of putting you in the midst of the action. Looking at a lightfield display is like looking through a window. It constrains your view much more than even watching a play performed live on stage, for instance.Movies and TV shows often rely on showing you a single perspective the director chooses. Allowing you to look at a different angle of a scene would mean you might miss important action going on in the scene (VR films have this same problem).
