What is the difference between 4D movies and 3D movies?

1. Definition:

4D movie: It is a new film and television product based on the 3D stereoscopic movie and the simulation of surrounding environment special effects, but it is not a four-dimensional space in the geometric sense. .

3D movie: A three-dimensional movie that superimposes two images to produce a three-dimensional effect. When the audience wears stereoscopic glasses to watch, they will have an immersive feeling. Also known as "3D stereoscopic movie".

2. Different effects:

4D movies: 4D movies usually introduce vibration, blowing, water spray, smoke, bubbles, smell, scenery and character performance simulation into 3D In the movie, a unique form of performance is formed.

These on-site special effects are closely integrated with the plot, coupled with the special equipment of theater chairs, to create an environment consistent with the content of the film, allowing the audience to experience the film through multiple physical senses of sight, smell, hearing and touch. The new entertainment effect it brings is immersive, thrilling, and exciting.

3D movie: Using two lenses to shoot images of the scene from two different directions at the same time, like the human eye, to make a movie film. During the screening, two sets of films taken by two cameras are simultaneously projected through two projectors, so that the two slightly different images overlap on the screen.

When viewers use polarized glasses to watch, each eye only sees the corresponding polarized light image, that is, the left eye can only see the image reflected by the left camera, and the right eye can only see the image reflected by the right camera. The picture will produce a three-dimensional feeling just like watching it directly.

Extended information:

4D dynamic cinema is relative to 3D stereoscopic cinema. It is based on 3D stereoscopic cinema, plus various special effects and professional dynamic seats in the surrounding environment of the audience. chair.

Environmental effects generally refer to lightning simulation/rain simulation/snowfall simulation/smoke simulation/bubble simulation/falling water droplets/vibration/spray simulation/jet/spray/leg sweeping/ear wind/ear noise /windy and many of them. A unique performance form has been formed, which is the 4D dynamic theater that is very popular today.
