In the local KayBee toy store last week I saw a set of stereo-imaging (3-D) glasses for the Sega game system. These are the liquid-crystal shutter type (like Tektronix makes), not the cheap red-blue stuff. The glasses were selling for about $50, and this relatively low price got me wondering about adapting them to the Amiga. The hardware ought to be trivial since a mere game machine is driving them, but is anyone working on stereo vision software for the Amiga? I know that there is a stereo CAD package for the ST, and I seem to remember Leo dropping a hint that he was working on some kind of stereo vision project. What I'm really wondering is if these inexpensive glasses would make a true 3-D imaging package possible for the Amiga. Leo? Anybody? (I hate to see the ST with something the Amiga doesn't have. :-) PS KayBee also had the Atari 2600 trackballs for under $10. The hardware hacks posted by myself and others work quite well with this trackball if you want a trackball on your Amiga instead of a mouse. -- Blaine Gardner @ Evans & Sutherland 540 Arapeen Drive, SLC, Utah 84108 UUCP Addresses: {ihnp4,ucbvax,allegra,decvax}!decwrl!esunix!blgardne ihnp4!utah-cs!esunix!blgardne usna!esunix!blgardne "Nobody will ever need more than 64K."

My eccentric friend is going to do just this (buy Sega glasses) as soon as he can find then on sale somewhere. The software should be pretty simple (We already have a decent red-blue 3D program). Gee... Maybe you could just draw the picture on an interlace screen (I knew that flicker was good for something...). The aforementioned friend already altered an atari trackball. He swears by it.

The stereo imaging projects by Leo and others sound great. One question: will you be able to use two or more sets of (Sega or other brand) glasses simultaneously? In other words, will the software/hardware be able to drive two or more sets of glasses (most normally worn by two or more people) watching the same image at the same time? Is this a difficult thing to implement (once you've got one working?) Robin LaPasha ruslan@ecsvax.UUCP

Thanks for the info Leo, I'll take a look in comp.graphics, and I'm looking forward to seeing what you're working on. If you don't post a message here when your experimenter's kit is ready, could you send me e-mail? -- Blaine Gardner @ Evans & Sutherland 540 Arapeen Drive, SLC, Utah 84108 UUCP Addresses: {ihnp4,ucbvax,allegra,decvax}!decwrl!esunix!blgardne ihnp4!utah-cs!esunix!blgardne usna!esunix!blgardne "Nobody will ever need more than 64K."

Not just 3D imaging available for the Amiga, but competition in the field already! (Unless Leo and Wade happen to be working on the same project?) Well, keep us posted, I'd like to see the occasional rumor/status report on how this stuff is coming along. Um, just thought of something. If we do have two seperate 3D efforts going on here, is it time to hammer out a stereo-image IFF spec? What about hardware/software compatibility? -- Blaine Gardner @ Evans & Sutherland 540 Arapeen Drive, SLC, Utah 84108 UUCP Addresses: {ihnp4,ucbvax,allegra,decvax}!decwrl!esunix!blgardne ihnp4!utah-cs!esunix!blgardne usna!esunix!blgardne "Nobody will ever need more than 64K."

I experimented with the 3D-breakout game that uses red-blue filters. The same effect would occur with Sega-style full color glasses, it being a geometric effect. The basic problem is that when you move your head to the right, the back of the perceived scene slews over to the left. To get two people side by side, they'd each have to put up with a rather distorted view. Or perhaps one person slouches down and the other looks over the first's shoulder, since there is no equivalent vertical distortion. Or I guess you could use two monitors. Perhaps one could get side-by-side support for 3D by using 4 interleaved views instead of 2. Each pair of glasses would be synched to one stereo pair, and would blank out entirely for the other person's view. You could then tell the program the off-center angle for each viewer, and it could generate views with no perceived distortion. This might cause a lot of flicker though. -- Charles Poirier (decvax,ihnp4,attmail)!vax135!cjp "Docking complete... Docking complete... Docking complete..."

The glasses we (Haitex) are bringing to market include glasses and an interface which is plugged into the Joystick port. Unless the guy doing our hardware has changed the design since two weeks ago (unlikely) the interface will support two pairs of glasses, which we will market independantly, when the second batch are shipped. As far as implementing 3-D goes, I have some code which we give to developers (and which will be available to the public once it's tested amounst a controlled group) to ease the job. None-the-less, some applications require extesive understanding of trig and basic algebra. Others are quite easy. Some drawbacks: 1) I work in (Benchmark) Modula-2, so if you don't you'll need to do some translation. 2) My code does not use intuition (for speed reasons). 3) My code does not support mult-tasking (as far as I can tell, this would require an O.S. change, though I have one re- maining possible kludge fix????). Sorry. We are activelly seeking 3-D applications and supporting the integration of 3-D support into existing products. If anyone has any intrest in doing any 3-D programs please get in touch with me. We would like to support some shareware/freeware app.s if possible. Thanks, Wade.

We didn't notice this effect, but we DID notice that the game was essentially impossible. There have been half-a-dozen or more of us who've tried it on my Amiga and *NO*ONE* can track the @#$^%@#$%^ ball in 3D. The room looks really great. The paddle is not too bad. But no way on the ball. I sure hope that it is not inherent in trying to do moving 3D images. __ / ) Bernie Cosell /--< _ __ __ o _ BBN Labs, Cambridge, MA 02238 /___/_(<_/ (_/) )_(_(<_ cosell@bbn.com
