What is naked-eye 3D?

Naked 3D refers to stereoscopic images and stereoscopic videos that can be viewed directly without any auxiliary equipment such as 3D glasses. Among them, naked-eye 3D image technology is relatively mature, and the representative is raster stereoscopic image. This three-dimensional image with naked eyes is very wonderful, the foreground is obviously prominent outside the painting, and the background is deeply immersed in the painting, which makes many viewers reach out and touch the scenery in the painting. However, this kind of naked-eye stereoscopic image can't see the stereoscopic effect on the computer or mobile phone. Only by seeing the real object of stereoscopic painting can we see the stereoscopic effect with distinct layers and strong stereoscopic effect.

At present, the naked-eye stereoscopic video technology is not mature, and only some fragments are shown to the public. Many people have never seen the complete naked-eye 3D video of the story.
