Cinemas enjoy real success in 3D movies. The only minus, big for many of us, is the active or passive glasses that all viewers must wear when we go to a 3D movie.
That is precisely why the CSAIL (Computers Science and Artificial Intelligence Lab) laboratory at MIT (Massachusetts Institute of Technology) has developed a new technology that can offer us the 3D experience without using glasses.
"Existing approaches to glasses-free 3-D require screens whose resolution requirements are so enormous that they are completely impractical, This is the first technical approach that allows for glasses-free 3-D on a large scale."
There have been such attempts that offered the display of 3D movies without glasses, but offered a visual experience with low resolution and reduced viewing angles.
The "Cinema 3D" prototype uses a series of lenses and mirrors made especially for cinema halls to display 3D material without glasses from any corner.
"With a 3-D TV, you have to account for people moving around to watch from different angles, which means that you have to divide up a limited number of pixels to be projected so that the viewer sees the image from wherever they are. The authors [of Cinema 3D] cleverly exploited the fact that theaters have a unique set-up in which every person sits in a more or less fixed position the whole time"
Those who develop this prototype tell us that the advantages over a classic 3D system, with polarized glasses, would be the preservation of color intensity, resolution, and the absence of glasses that could even break.
However, until this happens in cinemas, it will probably take some time.
"It remains to be seen whether the approach is financially feasible enough to scale up to a full-blown theater, But we are optimistic that this is an important next step in developing glasses-free 3-D for large spaces like movie theaters and auditoriums .”
