What is used to create a two-frame video with horizontal parallax?

A stereoscopic movie is a movie that can give people a three-dimensional vision and a clear sense of depth when projected. It is a video shot using different viewing angles similar to two eyes to create two pictures with horizontal parallax.

A stereoscopic movie is a movie that uses the viewing angle difference and convergence function of human eyes to produce a three-dimensional effect. Appeared in 1922. When this kind of movie is shown, two pictures overlap on the screen. Through the audience's special glasses or the radial semi-conical lens grating in front of the screen, the left eye of the audience sees the picture taken from the left perspective, and the right eye sees the picture taken from the right perspective. , through the convergence function of the two eyes, it is synthesized into a stereoscopic visual image.

History of development

In 1839, British scientist Sir Charles Whiston invented an eye-catching eye based on the phenomenon that "human eyes have different images". A kind of three-dimensional glasses that allow people's left and right eyes to produce different effects when viewing the same image. This is the principle of today's 3D glasses.

In 1922, the world's first 3D movie was "The Power of Love". Unfortunately, the film was lost long ago. Early 3D movies were mainly about showing three-dimensional effects, and the films often used guns pointed at the audience and objects thrown at the audience as gimmicks.

In 1936, films with a three-dimensional effect could be created using a dual-lens camera and polarizers, but this technology had many limitations. Later, with the development of technologies such as RealD three-dimensional and the popularity of movies such as Avatar, stereoscopic films were further widely promoted.
