What people say. Recommended as a decent review and technical overview of the Looking Glass holographic display technology.

On “Ask HN: What is a creative product you've discovered recently?”

It looks like their kickstarter has all the info: link Linus did a decent review of the tech back in 2019: link to this video

On “This is what Doom looks like on a holographic display”

Like other people have said, this looks like a Looking Glass dev unit or something. And here's a Linus Tech Tips video of it: link to this video They have some good footage (though obviously it's setup as a hype reel too). Edit: Skip to follow for "beauty shots": 4:45 and 8:50. 6:12 for funky shot of the 'flattened' image to give you a sense of what 'trick' they're playing

On “High-resolution holographic interface [video]”

Linus Tech Tips covered them before that gives a pretty good overview 0. It's a really cool tech and I hope it becomes more affordable in the future. I'd imagine actually feeling like a person is physically present will make Zoom meetings and such a lot less boring. 0 link to this video

On “Looking Glass starts shipping its 8K holographic display”

I believe they are shy to show it in high-quality video because the effective resolution is <900px. See my comment below for the math. Even in that TechCrunch gif, I believe I can already see pixel borders on the specular shading of the top part of the h. For an even clearer example, see the frog in full-screen at 3:31 here: link to this video

Yeah, that's not remotely accurate. 45 angles for each pixel: link to this video That's far more complicated than a lenticular sheet glued to LCD.

(Edited) The frog was on the low-res developer device. The much larger “8k” version introduced half way through link to 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).

On “Looking Glass starts shipping its 8K holographic display”

That’s wrong: technically it is nothing like the vertical grated sheet you see on cheap 3D posters etc. At 6 min 30 in link to 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

Interesting to see the 'modified' image before it's put on the display( link to this video ) Seems similar to how pixel art worked, and tricks artists used to get a better image with CRTs. link

On “Lenovo's concept laptop is real, transparent, and ready to impress”

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: link to this video They're taking a different approach, though using a stack of panels too. --- That crowd is still around: link
