3D has completely disappeared again from cinemas and TVs. It never takes off because it’s based on a misunderstanding, that a surface (screen, page) being flat means an image people look at on that surface is flat. That’s not true. People when watching standard TV or films are not seeing ‘2D’ images. They’re seeing images that look real to them, with depth. You can see that depth in chromadepth images, which show how colour for example can create depth without any binocular lenses, even with one eye. Look at this image for a little while, and notice the depth.
