What's the difference between 3D movies and 3D movies?

1.4d movie:

4D movie (or 4D movie) is a new film and television product based on 3D stereoscopic movie and simulating peripheral special effects, but it is not a four-dimensional space in the geometric sense.

2.3d movies:

The overlapping of the two images produces a three-dimensional effect, and when the audience wears stereoscopic glasses to watch, they feel immersive. Also known as "3D movies".

Second, the characteristics:

1.4d movie:

The effects of vibration, hair blowing, water spraying, smoke, bubbles, smells, scenery, character performance and so on are simulated into 3D movies, forming a unique performance form. These live special effects are closely combined with the plot, and the special equipment of the cinema chair creates an environment consistent with the film content.

2.3d movies:

Through the viewer's special glasses or the radial semi-conical lens grating in front of the screen, the viewer's left eye can see the picture taken from the left perspective, and the right eye can see the picture taken from the right perspective, which is synthesized into a stereoscopic vision image through the convergence function of both eyes.

Extended data

Related background:

4D movies are the product of the combination of stereoscopic movies and special effects theaters. With the more and more extensive application of 3D software in China, 4D movies have also developed rapidly.

Making stereoscopic movies with 3D software has its unique advantages. For example, the 3D scene itself has stereoscopic characteristics, and various parameters related to stereoscopic imaging can be easily adjusted in the software environment.

4D cinemas first appeared in the United States, such as the famous Spider-Man, Leaping over California, T2 and other projects, which all adopted the form of 4D movies. With the wide application of 3D software in 3D film production, 4D films have also developed rapidly in China, and the production level of screen effects and live stunts has made great progress.
