3D movies are very common nowadays like Resident Evil: The Final Chapter, La La Land and most recently The Great Wall, 3D movies have generated new technologies and investments to make it better, like the IMAX 3D experience.

The trend started recently in the early 2000s, they all seem like something relatively new, but that's not how it goes. 3D stereoscopic photography was first created in the early 1840's, invented by Charles, by mimicking 2 eyes, a stereoscopic camera takes 2 images at once, one to represent each eye view one to represent each. Each photo offset by a small distance about the same distance as our human eyes are apart, it creates perspective. In the past, special viewing devices were used to view 3d photos your left eye sees the left image and then right eye sees the right, and when these two views when seen at once, there are combined by the brain into one image, which your brain imagines as depth. The below image is a stereoscope,
In the 1890s, the first patent to film motion pictures in 3D filed in the US by Will Green, and his idea was a machine that runs 2 strips of film in synchronization, it was successful but ignore, because it was impossible for large theater viewing. In 1915, Edwin Porter and William Waddell turns on a test film to audience in New York, His films are films which had left and right lens superimposed over one another with red and cyan or red and green-tinted images, as audience would wear tinted glasses to block out one image from one eye and the other image from the other, giving the illusion of 3D.

In 1922, William Cassidy and Laurence Hammond created an alternative method for 3D films called Teleview, which when a single strip of film projects left and right images one after another in the audience looks through a viewing machine which opens and closes shutters in front of each eye in sync with the images that appear on the screen.
