Colossal Holograms

However - the effect can still be fairly magical and the distinction is lost on most people I've shown it to (we have the smallest 6" model).
It genuinely looks like a full-color animated holographic display in most likely viewing scenarios.
The loss of vertical parallax changes computation from an N squared to N problem. An interactive display like the looking glass provides vertical parallax cues as a result of user interaction (rotating the object vertically with user interaction).
This class of display also does not have accommodation cues, but in the range of 3d cues accommodation is the weakest.
Looking Glass displays are great! Shawn and the team has done careful, practical engineering work to get these displays out there.
Ref: I have a PhD in 3D display technology and worked with holography pioneer Steve Benton and his group at MIT to develop the most advanced holographic stereograms at the time. I own a Looking Glass display.
I had hoped plenogram would catch on (to make the connection to the plenoptic function that describes the travel of light in a scene).
This isn't even close, though. Horizontal parallax only and only a few dozen angles (over a wide FOV!) puts it more in the territory of lenticulars than true lightfield displays. To be fair that is enough to achieve a 'wow factor', and a true lightfield display is a Hard Problem (that Fovi3d are trying to solve, if you're interested in the state of the art).
With the screen, they do match, as only what's on the screen is 3D. In that sense, it is like looking at a box with something 3D in it, versus being submersed inside something 3D like with the glasses.
tl;dr With the screen you can move your head around and the world moves with it, so there is no sensory mismatch. But turning your head when going into a 3D warp speed starscape with 3D glasses on might easily cause someone to ralph on the poor sole sitting in front of them.
- horiz/vert max angle (to be able to walk around): the widest=the best
- horiz/vert max angular resolution (to avoid the step effect while walking around): the finest=the best
- of course, the usual suspects: refresh rate/resolution/number of colors/color accuracy/luminosity
horizontal: 40-50 degree viewing angle, with angular resolution of 45 steps. vertical is not paralax at all. recommended 1 - 30 ft viewing distance.
the 8k measurement is the total of all the display layers, so what you'll see is a fraction of 8k resolution. refresh rate: 60Hz.
i think all those measurements are true for all three display sizes manufactured by looking glass, except the smaller screens are 4k.
the blog also mentions "over a billion-count color gamut".
I wonder if the naming is a coincidence or a nod.
That depends on the patent status. Without patent => nod; with patent => theft.
All of which were probably referring to the same concept: viewing the other side of reality
It is just like decade old stereo camera like this: https://www.amazon.com/Fujifilm-FinePix-Real-Discontinued-Ma....
Bigger size and bigger resolution is a great step up here - I hope they get to continue in that direction!
From what I gather, this is the same tech used in a 3DS - scaled up to an impressive scale.
In fact, given the principle of the reversibility of light, if you had a screen the same size and pixel density as your camera sensor you could use the exact same lens array to output a close approximation of the captured light field, without any post-processing of the captured pixels!
And if you have them, I reckon a screen with a mouse is all you need to view them to technically know how to proceed.
Usual marketing scam, make the public think creating a 3D hologram device will somehow get them 3D things.
The viewing angle is very specific; if you’re off to the side it doesn’t work, but the sweet spot is big enough or perhaps 4-5 people to stand in front of.
Given they’ve quietly delivered on exactly what they (as far as I can tell) promise, I see no particular reason to believe the 8k isn’t real.
Obviously wait for the detailed reviews to roll out, healthy skepticism (for example I have no idea what the SDK is like; perhaps it’s only capable of rendering specific types of 3D content)... but this isn’t a scam.
But most regular 3D content will display as expected.
It's still pretty impressive tho.
Do you mean the effect doesn't work with back to front motion? Like that pan can't start in the back and move forward?
That said, that's still basically "3D but without glasses", not exactly the Holodeck "hard light" future tech many people think of when they hear "real hologram".
That requires
1. The imagine coming "out" of the screen such that you can even see the image at 90º to the projector
2. The image occluding the physical background.
As far as I understand, such a thing is impossible as seen in the still above (i.e. from a single projector), but can be fakes by using stuff in the air to scatter the light, like this research project (1) or this not-great version that uses fog (2)

This means 3d impression works even for people with reduced stereoscopic eyesight, and does not create headaches due to a mismatch of scene depth vs. physical display depth.
Such holographic displays do exist, e.g. www.seereal.com (which BTW recently received an investment by Volkswagen).
For a "low tech" example of such effects take a look at http://amasci.com/amateur/holohint.html and related content.
I know one of the cofounders, Alex, a bit. He’s a really earnest and excited person. He’s been working on 3D led tech for a long time. It’s been fun to see how’s his ideas have progressed. I have no reason to doubt their claims.
FYI, they are not the only company working on these types of displays. There is also an Irish company (I forgot their name) working with panels made by Panasonic. I think theirs are higher res than 8k.
(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.)
This is spam
The 15” is $3000
They’re amazing though; I’ve seen one in person and it’s pretty much exactly as described.
And there are legitimate commercial use case for AR - e.g.: automotive manufacturing and building construction.
The biggest impacts to Magic Leap's prospects came from the premature over-hyping of the product as well as microsoft beating them to the punch with the HoloLens.

There are voxels in front of the screen for which that holds.
