Does anyone know about software for IBM AT (or 386) which would produce pairs of images, in green and red, of a 3D object, which when viewed through green and red glasses, would give 3D illusion? Thanks in advance -- Andrzej Pindor University of Toronto Computing Services pindor@gpu.utcs.utoronto.ca

These would make GREAT GIF files!!!!! :) :) Especially 640x480x256 ! I wonder if it is possible to "simulate" a red-green pair from a 2D image? woops.... I just realised that 256 colours would not be required for an image with only red and green colours..... :) Steve ----_--_-_-_--_-__-_------_-__---_-___-_----_-____-_-_--__-_--_--___-_-_-_--__-_ Steve Balogh VK3YMY | steve@monu6.cc.monash.edu.au Monash University (Caulfield Campus) | 37 52'38.8"S 145 02'42.0"E ...ICBM PO Box 197, Caulfield East | +61 3 573 2266 Voice (Office) Melbourne, AUSTRALIA. 3145 | +61 3 573 2100 Fax

I don't have exactly what you want, but EMail me at lmeyer@well.sf.ca.us and I will send you a StereoGraphics software manual with the algorythms you'll need to write your own... Lhary]

It is possible to connect LCD-shutter glasses to an EGA or VGA display to show real 3D images. The only problem is to change display between each horizontal retrace period (ie. 60 times in a second in VGA). It should be possible to alternate EGA display pages or VGA color palette fast enough.

My shareware ray tracer, Vivid, comes with a utility that lets you combine two images into a red/blue 3d image. The results are pretty good. Maybe I need an option for green? >woops.... I just realised that 256 colours would not be required for an image > with only red and green colours..... :) Since you're talking VGA you've got a possible 64 shades each of red and green. That works out to a possible 4096 different colors. In practice the 256 colors available with VGA works quite well. >Steve Balogh VK3YMY | steve@monu6.cc.monash.edu.au Stephen Coy coy@ssc-vax.UUCP BDIF

Remember to use yellow where the red and green cross, but that takes only another 64 (193 total, 64 each red, green, and yellow and a background, probably black).

No, you need to dedicate 4 bits to red and 4 to green, so that the proportions are correct where they cross. ____ \/ o\ Paul Crowley aipdc@castle.ed.ac.uk \ / /\__/ Part straight. Part gay.

Better yet, why not get the files from where I keep them, so you'll always get the latest version. The main archive site for the Sega 3D files is at vega.hut.fi and the files are in pub/mac/finnish/sega3d Most of the files are for the Macintosh, but there are text versions and even one GIF picture with the circuit description. The plans are very easy to adapt to almost any application and I see no reason why the circuit couldn't be made to emulate the much more expensive StereoGraphics CrystalEyes (except that the shutters might not be fast enough for 120 Hz). ____________________________________________________________________________ / Juri Munkki / Helsinki University of Technology / Wind / Project / / jmunkki@hut.fi / Computing Center Macintosh Support / Surf / STORM / ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
