3D movies without annoying glasses?

Spectacular 3D effects in the cinema to must experience, but without the annoying glasses put on this desire of many movie-goers could be true. What was possible only in a small format, namely to see 3D films without appropriate glasses, to come to the big cinema screen.

They are annoying, but you take them in stride because there just no other way. In order to enjoy the spatial effect of a film shot in 3D, we must put appropriate glasses. A team of researchers has now shown without feeling. Scientists have a well-known technique designed further so that it is cinema-grade format. There is a prototype of the ‘cinema 3D’.

Technology is based on Parallax barrier: each eye sees a different image

Built the prototype in the computer science and Artificial Intelligence Laboratory (CSAIL) of Massachusetts was Institute of technology (MIT), together with scientists of the Israeli Weizmann Institute and the Saarland University. “In the previous tests, 3D movies to be able to see without glasses, screen with such a high resolution is needed, so that the technique is completely impractical”, says MIT Professor Wojciech Matusik. The new approach was the first that do 3D without glasses in the large possible.

The technique used by the scientists for this, based on the so-called Parallax barrier. These are slanting stripes masks or lenticular, which deflect the light of two images in different directions. Thus, each eye sees other pixels, which simulates the effect of a depth. For this to work, the Parallax barriers must remain however in a fixed distance and angle to the Viewer. For a larger audience in the cinema, that was previously non-transferable.

Scientists use that each movie has firmly

Because it can be but to assume that every movie has its place with limited freedom of movement, the scientists on the idea to integrate multiple Parallax barriers for every or almost every place in the cinema were its own. This is achieved by using a series of lenses and mirrors.

Repeat the special optical system over the entire Auditorium.

This in theory harmonious arrangement, was not practical so far still the scientists agree. Their prototype worked while with a test audience as predicted. However, he needed 50 of lens and mirror sets on a screen that was not much bigger than a sheet of paper.

The team will now build a larger version and improve the look, so a higher resolution can be achieved. “We have to wait, whether this approach for the dimensions of a large cinema hall is at all financially feasible”, says MacDonald. “But we are optimistic that this is an important step in the development of 3D without glasses in the great Auditorium.”

Printer software (Germany) for stop-motion films

You have correct faces with expression: the characters in animated films can tear up the eyes, wrinkles, can run on red. However, the facial expression is not virtual.

Every facial expression is filmed with a camera with characters from the 3D printer. The US Studio laika used printer software from Germany. You read more about here.
