Lines: 21 In-reply-to: andyrose@batcomputer.tn.cornell.edu's message of 14 Nov 90 20:19:40 GMT There's another technique which might help some, which Jim Kajiya at CalTech was working on about two years ago, when he described it to me. The idea is to take a stereo display like the CrystalEyes (we happened to be looking at the Tektronix display on a Tek 4330 workstation, since that's who I work for), and add a gadget which tracks the position of the glasses relative to the display. We talked about using a scanner, like what you see in a supermarket checkout counter, and a reflective strip on the bridgpiece of the glasses. Then change the viewing parameters to follow the change in position of the viewer's eyes. This allow you to bob you head up and down and right and left to get changes in parallax. Unforunately, it only works for one viewer per display. I haven't heard if Jim has continued work on this idea. If you're out there Jim, can you tell us? -- ------------------------------------------------------------------------ Speaker-to-managers, aka Bruce Cohen, Computer Research Lab email: brucec@tekchips.labs.tek.com Tektronix Laboratories, Tektronix, Inc. phone: (503)627-5241 M/S 50-662, P.O.
