Re: [ccp4bb] 1990s-style stereo viewer
For what it’s worth, side-by-side stereo-adjustable mirror glasses are still available. Also ones that use prisms to achieve a similar, though not identical, effect. I’ve bought various objects, because I *still* prefer building in 3D. I think one understands better what one is looking at. Back at Yale, as the yalies from the 80s on ccp4bb will remember, a large glass mirror setup was built that was hinged and fit over the top of the PS2 (and then ?PS300?) screen so that you could do side-by-side without having to adjust anything. You just poked your nose at the divide between the two central mirrors. I built a similar kind of device myself using mylar mirrors and cardboard a few years ago, but without the hinges. Ah, the past, a different country. Adrian On 25 Jul 2023, at 12:53, Alastair MC EWEN mailto:alast...@igbmc.fr>> wrote: Hi Harry, You are very welcome.

Re: [ccp4bb] 1990s-style stereo viewer
Hi Jon Thanks for this, but as Wim and Adrian have pointed out - I can’t have been referring to a PS300 (maybe it was one of the ESV series, I don’t know. I might have remembered if I’d actually had any useful phases and done any building… by the time that happened we’d moved onto SGI machines) because they had the set-up your pictures are of. However, these pics may still be of use to me. Thanks everyone who has replied to this - I knew this would be the right place to ask!

Re: [ccp4bb] 1990s-style stereo viewer
Yes but this is just classic side by side stereo. I had one until quite recently. My memory of the ps300 is that it was fullscreen, not side by side with the display synced as another poster said. I also feel that the ps300 didn’t flicker because it was a raster display so no matter how many lines it still displayed at 30 or 60 hz. Don’t remember. The ps2, on the other hand drew each vectors line by line - and my god that flickered awfully with “complex” objects.

Re: [ccp4bb] 1990s-style stereo viewer
Can’t have been a PS300 in that case! I’ve since been reminded that they were made of wood (the stereo viewers, not the Evans and Sutherland.

Hi folks I was wondering if anyone has a photo of the old-style head-mounted stereo viewers that used to be used to see 3D images from wall-eyed stereo pairs? I don’t mean the ones that were used to view the side-by-side stereo images that once appeared in printed journals, but the ones that were used for advanced computer graphics machines like E PS300.
