Message-ID: <2045@usceast.UUCP> Date: Sun, 20-May-84 00:53:27 EDT Article-I.D.: usceast.2045 Posted: Sun May 20 00:53:27 1984 Date-Received: Tue, 22-May-84 08:22:06 EDT Organization: Csci Dept, U of S. Carolina, Columbia Lines: 32 You may have heard that two professors here at the U of SC developed a 3d television system last year. I don't know what has happened to it since, but that's not relevant to what I'm about to ask. The most impressive thing about the system (I have seen it briefly) is that it takes no special glasses, and the effect can be observed even with one eye closed! The process is secret, but I have thought about it a little and wondered if this makes sense: The effect can be seen one eyed because information from both perspectives is present on the screen in alternating frames, thus with persistence of vision, the brain can reconstruct depth without input from the other eye. This is such a simple idea that I suspect it must have been thought of before. Does anyone know if it has been tried with movies? It seems that it would be easy to implement : just have a camera with two lenses and have them alternate in exposing frames. The final product would need no special equipment to project nor any headache inducing glasses to view. How about if folks? Would this work? Has it been done, or is the idea all wet?
