It is known as 3D (three dimensions ) to technique which allows reproducing three-dimensional visual information to create an illusion of depth in an image. You can talk, in this way, about 3D movies, 3D TVs, etc. It is worth mentioning that the concept of 3D has two main interpretations today, which differ substantially: content created from polygons to give the feeling of depth; stereoscopic content, presented so that the brain perceives it arranged in three dimensions, as if the visualization medium were a window to another reality and not a flat picture.
He success Both forms of 3D have been and continue to be very different. Stereoscopy is a very old technique that involves showing each eye a different perspective of the same scene, similar to what happens in everyday life, so that the brain does not have to process the depth of the image, as if It happens with traditional movies and photographs. Currently, there is a wide variety of cameras that have two individual lenses to simultaneously capture two views of each frame.
To play a stereoscopic video it is necessary to have a screen special, capable of refreshing at twice the speed of a conventional one, so that each eye receives the content with the same fluidity as the other; also, depending on the technology used, the use of glasses that show the appropriate image to each eye may be required, although there are screens that simply require its users to be located within a certain range of positions to enjoy the content without the need for accessories.
On the other hand is the third dimension represented from an alteration of the scale of the elements on the screen, emulating the old drawing techniques to recreate scenes in perspective, such as the vanishing point; Most current video games, for example, feature scenarios and characters created from points that are located in a three-dimensional space, so their positions seem to change as they approach or move away from the camera.
The cinema takes advantage of both techniques to attract the attention of the public with intense experiences; When both are combined effectively, the feeling of perceiving the third dimension can be truly shocking. However, it is necessary to point out that people with view Monocular can not enjoy stereoscopy.
