What's the difference between 4D movies and 3D movies?

1, 4D movies have more lighting (lightning in the movie) and sound (full stereo, each seat has speakers, and the sound varies according to the movie plot) than 3D movies.

2, the difference between the film source: 3D movies are generally feature films, focusing on the plot, followed by the 3D effect. And "4D" is generally only ten minutes, focusing on the effect, and the plot is very simple or even no plot.

3. According to the plot of the movie, there will be water, snow, fog (spraying water mist or snowflakes from the top floor of the theater) and vibration (appropriately vibrating according to the plot of the movie), but 3D movies don't.

Extended data 3D movie is a movie that uses the difference of visual angle and convergence function of human eyes to produce stereoscopic effect. Appeared in 1922.

When showing this film, two pictures are superimposed on the screen. Through the audience's special glasses or the radial semi-conical lens grating in front of the screen, the audience'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, and the stereoscopic image is synthesized through the convergence function of both eyes.

4D movies are the product of the combination of stereoscopic movies and special effects theaters. In addition to three-dimensional visual images, the screening site can also simulate natural phenomena such as lightning, smoke, snowflakes and smells, and the audience's seats can also produce actions such as falling, shaking, blowing, spraying water and sweeping legs.

These live special effects and three-dimensional pictures are closely combined with the plot, which brings new entertainment effects to the audience in visual and physical experience, just like being there and nervous.
