The difference between three-dimensional movies and four-dimensional movies

People's left and right eyes look at the same object, and the eyes see different angles, so the images formed on the retina are not exactly the same. After the two images are synthesized by the brain, they can distinguish the front and back, the distance and the distance of the object, thus producing stereoscopic vision. The principle of stereoscopic film is that two cameras imitate the visual angle of human eyes and shoot at the same time, and two projectors project onto the same screen at the same time for left and right eyes to watch, thus producing stereoscopic effect.

Four-dimensional film

4D cinema is a new film and television product based on 3D stereoscopic movies and simulated environmental special effects. The so-called 4D movies are also called 4 D movies; That is, a three-dimensional movie and the surrounding environment simulate to form a four-dimensional space.
