Any info on how it works?

There are multiple transparent lcd (or maybe led - idk) screens layered on top of each other. A different image is rendered on each layer to appear 3D. A single 8k video stream is sent to the display. Each 8k image is subdivided into multiple smaller images, one for each layer. So the entire image is 8k, not 8k per layer. I know one of the cofounders, Alex, a bit. He’s a really earnest and excited person. He’s been w…

Is this essentially the technology the 3DS used, only scaled up?

(I ask for clarification, not to diminish the achievement. If it is, and it works well, it's still a nice advancement. Nor am I saying it was invented for the 3DS.)

I have 4k version and it is very very bad. 4k is actually 4k/30 (number of angles). Pixels have the size of a fist.

Based on that, how do you think an 8k version would compare? Enough resolution, or still lacking?

What's the resolution of each layer and the resolution of the depth ?

The video game Prey2 features similar technology also called LookingGlass. It has a fairly prominent role in the story line. I wonder if the naming is a coincidence or a nod.

It's also the name of a game studio with a number of neat titles, some rock band, and perhaps most importantly, sequel to Alice in wonderland: Through the Looking-Glass, and What Alice Found There All of which were probably referring to the same concept: viewing the other side of reality

Also Sun's Project Looking Glass 3D desktop environment: https://en.wikipedia.org/wiki/Project_Looking_Glass

The camera motion makes it look like they're trying to hide something... like the effect only works horizontally, not vertically.

The looking Glass display is horizontal parallax only (HPO). HPO is a common information reduction method in the 3D display world. Most holographic stereograms, all rainbow holograms, and all 3D lenticulars are HPO. Occlusion, horizontal motion parallax and stereoscopic cues are preserved, which are our primary 3D cues. The loss of vertical parallax changes computation from an N squared to N problem. An interactive d…

Am I correct in assuming this is a parallax-barrier display similar to that on the Nintendo 3DS but much larger and higher-resolution?
