3D technology is and how it works? Lately, due to the release of films such as Up, Avatar and Ice Age 3 in format 3D Digital, has popularized the 3D technology, which is certainly giving a lot to talk about. In reality it is not an innovative technique, since it exists since the 1950s, although there is no denying that he has been suffering multiple evolutions throughout its history. We all remember glasses Anaglyph carton, formed by a red filter and another Green, who were able to generate a slight sensation 3D to synchronize two apparently undistorted images. As well, the technology that we find ourselves in the current cinema part from the same base, but with important technological differences. Most of the Chambers that broadcast movies in 3D Digital currently do with the RealD projection system.
This system needs a single projector, and not two as conventional 3D, thus avoiding a large investment. The RealD system prevents the use of two projectors to the Insert a different image to each eye, at high speed, and repeating them three times without changing the frame rate of film format (24 frames per second). With the help of properly Polarized Sunglasses, we perceive the feeling of perspective and therefore the 3D effect. 3D, a new hope for producers and movie theaters the number of feature films recorded with this technology, as well as the number of rooms that broadcast in digital 3D is in constant growth. Thereby seeks the reaffirmation of movie theaters, which until now were suffering a setback in terms of audience, and therefore revenues. It is evident that this loss of viewers is due, in large part, to piracy, although we also consider just attributed part of this responsibility to the film industry itself, since in the last decade, the number of original scripts has fallen drastically, giving way to continuous screenings of remakes, sequels and adaptations from other works.
