3D projectors

3D

— the ability to play a "three-dimensional" video projector, when the illusion of a third dimension — depth — is created on a regular flat screen. Such video is recorded in a special format in which the visible image is divided into two parts — for the left and right eyes — and viewed through special glasses (which most often need to be purchased separately). 3D content provides a powerful effect of presence and a sense of immersion in what is happening. At the same time, it should be taken into account that such an image puts forward increased requirements for the quality of the screen (glasses often darken the visible image); and in some visual disorders (strabismus, missing one eye, etc.), normal 3D viewing is not possible.
