I could hardly believe my eyes! - Looking Glass Holographic Monitor

Looks like a useful step towards 3D displays. By stacking a bunch of these transparent panels on top of each other, you could display 3D objects without needing 3D glasses: ----o----- Layer1 ---o-o---- Layer2 ---o-o---- Layer3 ----o----- Layer4 (etc) The depth resolution would be kind of crap, but there'd probably still be uses for it. Maybe layers wrapped as cylinders? Pretty sure there's an existing crowd trying something like this a few years ago: ▶ this video They're taking a different approach, though using a stack of panels too. --- That crowd is still around: link

That’s wrong: technically it is nothing like the vertical grated sheet you see on cheap 3D posters etc. At 6 min 30 in ▶ this video they show the pixel sub mapping - and it isn’t just vertical bars. Edit: If they used a vertical grated sheet, there should be vertical lines at high contrast edges at a 45 pixel pitch. look at the green book at 6:22 and close-up at 6:27, and there seems to be vertical smear (not just what you might expect from horizontal smear). Example of a 3D lenticular print without the lenses to compare against: link from link

(Edited) The frog was on the low-res developer device. The much larger “8k” version introduced half way through ▶ this video has some good tech detail, with the raw pixel mapping shown at 6:30. Calcs seem about right since raw pixel count was stated as 43 million, although it was implied elsewhere they split RGB sub pixels too (which sounds wrong I admit), so maybe 43 million divided by 15? Our eyes are more sensitive to luminance than colour, so maybe they did something there (however, not that I could see from the raw pixel mapping at 6:30).
