The difference between 4D and 3D movies?

1, 4D movies than 3D movies have more lights (lightning in the movie), sound (full stereo, each seat has a speaker, according to the different plot of the movie and the sound is different)

2, the difference between the sources: 3D movies are generally long movies, focusing on the plot, followed by the 3D effect. And 4D is generally only ten minutes, focusing on the effect, the plot is very simple or even no plot.

3, 4D movies will be based on the plot of the movie, there will be water snow fog (from the top of the theater spraying water fog or snow), and vibration (according to the plot of the movie appropriate vibration), while 3D movies do not.

3D movie is the use of human two eyes perspective difference and convergence function can produce three-dimensional effect of the film. It appeared in 1922.

This kind of movie is shown when two images overlap on the screen, through the audience's special glasses or the curtain radial semi-cone lens grating, so that the audience's left eye to see from the left perspective of the picture, the right eye to see from the right perspective of the picture, through the two eyes of the convergence of the function of the synthesized into a stereoscopic visual image.

4D film is a combination of stereoscopic film and stunt theater products. In addition to three-dimensional visual images, the screening site can simulate lightning, smoke, snow, smell and other natural phenomena, the audience's seat can also produce falling, vibration, wind, water, sweeping legs and other actions.

These live stunt effects and three-dimensional images are closely integrated with the plot, giving the audience a brand new entertainment effect in terms of visual and physical experience, as if they were in the realm of the intense excitement.
