1839, the British scientist Sir Charles Whiston invented a kind of stereoscopic glasses according to the phenomenon that "two eyes of a person have different images", so that people's left eye and right eye can produce different effects when looking at the same image. This is the principle of 3D glasses today.

1922, the world's first 3D movie was The Power of Love. Unfortunately, the film has long been lost. Early 3D movies mainly showed three-dimensional effects, and gimmicks were often aimed at the audience and threw objects at them.

In 1936, a film with stereoscopic effect can be produced by using a dual-lens camera and a polarizer, but this technology has many limitations. After the development of RealD 3D technology and the popularity of Avatar, stereoscopic movies have been further widely promoted.

1952, The Demon of Boisne, about African exploration, was recognized as the first real 3D feature film in history. The slogan of the film is "The lion is on your leg and the lover is in your arms". Although Life magazine called the film "cheap and absurd" at that time, the audience still enthusiastically crowded into the cinema to experience the "natural perspective" in the film.
