From Stereopticons to Holograms A stereopticon is a slide projector that combines two images to create a three-dimensional effect. A development of this technology is a computer screen which can display traditional 3D images. In fact, 3D displays form the final image from only two images, one for the left eye and one for the right eye. The screen always displays the same image angle regardless of the viewer’s position. With holographic 3D images, instead, if you change position, you can see different angles of the image, as in reality. Holographic 3D screens differ in the number of viewpoints they can display, from 4 to 45, making the experience much more complete. The market tends to label the screens with few points of view as ‘holographic 3D’, and simply ‘holographic’ those with a high number of points of view. Holograms are images that float in the air without any screen. However, this is unrealistic and we only see it in films. To be able to create holograms, not only does technology need to evolve, but also content creators have to get used to working with three dimensions. What is a stereopticon?
