What does a 3d movie mean?

3D is the abbreviation of "Three Dimensions" in English, and Chinese refers to three dimensions, three dimensions and three coordinates, namely, length, width and height. D is the prefix of English Dimension, and 3D refers to three-dimensional space. That is, three-dimensional movies, which are usually called three-dimensional movies internationally.

There is a three-dimensional space in a 3D movie. For example, we can see multiple faces, which has stronger three-dimensional effect and more positive effect than 2D plane, just like we are in a scene.

The application of 3D technology is very extensive, including the development and production of cultural and artistic products for visual expression, such as film and television animation, animation and games, the design and production of physical products such as automobiles, airplanes, household appliances and furniture, and the simulation and simulation of the virtual reality of human interaction with the environment.

The principle of 3D movies—

Ordinary movies are projectors, which hit the picture on the big screen, and the light enters the audience's eyes through the reflection on the screen, but 3D movies are equivalent to one left and one right. The two projectors hit two sets of pictures on the big screen respectively, with a deviation of several centimeters; Once you put on 3D glasses, what you see with your left eye is the picture of the left projector due to the special light projected and the lenses of the glasses. The right eye sees the picture of the projector on the right.

In fact, these two pictures are different. But judging from the pictures taken by the left and right lenses at the shooting scene. So sitting in the cinema is equivalent to going to the filming scene and seeing the picture with your own eyes.
