Paper Abstract

3DTV Corporation has a variety of new products for stereoscopic computer graphics and video. There are inexpensive kits for frame sequential graphics on virtually every computer platform. A system for IBM PC compatibles has a 3DROM with games, animations, photos, tools, information, and a user configurable interface for parallel or serial ports with passthrough, status LED's and a jack for 3 new varieties of LCD shutter glasses. The StereoSpace Model 1 is a universal interface for LCD glasses with LED frequency display, VGA, parallel and serial input, sync pulse insertion for the above/below format, buttons for image adjustment and polarity reversal and ability to be computer controlled from Windows or other operating environments. Model O is another universal interface that uses optical iindicia on the screen to trigger glasses. The SpaceCam is a twin lens microprocessor controlled video camera with synced zoom and convergence. The SpaceBar offers manual or computer control of two cameras. The improved Model 200 StereoMultiplexer offers split screen modes and DB25 or BNC breakouts for making field sequential stereo with any two cameras. The SpaceStation can convert NTSC or PAL 3D video in composite, YC or RGB from nearly any format into separate R and L channels or into nearly any frequency field sequential RGB or NTSC. It can multiplex or demultiplex top/bottom, side by side or field sequential video with parallax shifts, color correction and field delays. It is finding use in perceptual research and in 3D video theaters with 1 or 2 projectors. The SpaceScanner converts field sequential stereo between PAL and NTSC. The StereoPlate Models 1 and 2 polarize light for 3D viewing with passive glasses and can fit 3 tube projectors or 17 inch monitors. For low end applications the SpaceSpex process gives full color analglyphs with inexpensive glasses.
