- jdkee 7y agoAnyone know how much these are going for, roughly?
- tatersolid 7y ago$Texas
- tinus_hn 7y agoA tiny version costs about $600, so probably a lot.
- paggle 7y agoI don't. But based on their other prices and the complete lack of any competition here I'd guess about $40-80K.
- jonny383 7y agoOff-topic: Can someone please write a Firefox extension that removes that _stupid_ fucking popover on medium "Pardon blah blah give us your money". Does that shit really need to take over the entire fucking screen?
- proaralyst 7y agoI think uBlock Origin with one of the annoyances lists blocks this
- jonny383 7y agoI have uBlock Origin installed and just received the popover :(
- helb 7y agoThis should work (add it to "my filters" in uBlock settings and click the checkmark/apply button): medium.com##div[tabindex="-1"][aria-modal="true"] Tested in FF 70 with uBlock Origin and tracking protection enabled. EDIT: Here's a simple blocklist with more Medium banners and popups. Can be added via "Import…" at the bottom of "Filter lists" tab in uBlock Origin settings. I'll try to update it when i encounter some new Medium stupidity: https://helb.gitlab.io/medium.com-blocklist/medium-blocklist.txt https://helb.gitlab.io/medium.com-blocklist/medium-blocklist... If you hit the (monthly?) quota for articles without an account, just clear cookies & localstorage.
- chacha2 7y agoMake sure you've ticked on all the filter lists in the preferences.
- vallode 7y agoReally nice tip: Click the little keylock on the left side of the address bar when on medium, go into site settings, under javascript block it and medium articles will now load as just pure easy to read text :)
- laurent123456 7y agoFor me it removes images when doing this. I'm only surprised they don't require JS to display text yet.
- concordDance 7y agoThis seems too good to be true.
- nkoren 7y agoA friend of mine has seen it. Says that it's true.
- wokwokwok 7y agoI can’t speak for the 8k one, but I’ve personally seen the small one (9”) and was completely blown way by how good it was. 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.
- andybak 7y agoI've used their Unity SDK and it can render most content you throw at it. It has similar limitations to VR - faux-3D but really 2D post processing effects won't work. Sometimes shader tricks will break the expectations of the renderer. But most regular 3D content will display as expected.
- pluma 7y agoNote that this "only" adds depth. It can't make anything appear to "come out of" the screen, the effect is more like a window. It's not like holograms in science fiction. It's still pretty impressive tho.
- tyingq 7y agoThis looks like "coming out of the screen" to me: https://miro.medium.com/max/1200/1*-nm0AvcydVzyhgDFdh6V2g.gif https://miro.medium.com/max/1200/1*-nm0AvcydVzyhgDFdh6V2g.gi... 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?
- ithkuil 7y agoDo you think something like this would significantly improve experience for remote workers?
- tiborsaas 7y agoNo. Better video won't help you with the basic struggles of social life, isolation and having to be on chat large portion of your working day.
- p1mrx 7y agoThe camera motion makes it look like they're trying to hide something... like the effect only works horizontally, not vertically.
- soylentgraham 7y agoThat's pretty much true
- andybak 7y agoYep. It's actually closer to a lenticular effect than a true hologram. 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.
- mhalle 7y agoThe 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 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.
- chmike 7y agoAre the Looking Glass display real holograms with light interference patterns ? Or are they emitting different pixels in different view angles ?
- targonca 7y agoYou would need a beefy machine to render 45 8k images per frame.
- hughes 7y agoThis is 45 image segments encoded into a single 8k signal. I have a smaller one, and it's amazing, but its 4k image input results in approximately 800x600 equivalent for each rendered angle.
- brazzy 7y agoAny info on how it works?
- matt_the_bass 7y agoThere 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 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.
- jerf 7y agoIs 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.)
- Doxin 7y agoAs I recall the 3DS used a lenticular lens: you see different images based on the angle to the display. Wikipedia has some more information: https://en.wikipedia.org/wiki/Lenticular_lens https://en.wikipedia.org/wiki/Lenticular_lens
- spyder 7y agoWhat's the resolution of each layer and the resolution of the depth ?
- theophrastus 7y agoThat's impressive; and for me a bit reminiscent. I got my doctorate staring at macromolecular structures through various attempts at presenting them in 3d. One of the earliest I encountered was called a "Richard's Box"[0]. That setup was a set of clear plastic sheets on which were plotted 'slices' of electron density which were subsequently stacked-up with suitable sized spacers and you looked down through the stack with an lamp beneath. This approach sounds very similar, but with an active display in place of each sheet of plotter output.

- maest 7y agoThe 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.
- classified 7y ago> ...coincidence or a nod. That depends on the patent status. Without patent => nod; with patent => theft.
- qnsi 7y agoPatent or trademark?
- setr 7y agoIt'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
- djmips 7y agoLooking-glass was just a peculiar literary term for a mirror in the 1800s. A reflective glass you would look at.
- rgovostes 7y agoAlso Sun's Project Looking Glass 3D desktop environment: https://en.wikipedia.org/wiki/Project_Looking_Glass https://en.wikipedia.org/wiki/Project_Looking_Glass
- dwoozle 7y agoIt’s another word for mirror and has cool vintage/steampunk/Victorian associations so it’s going to be used by a lot of different people.
- Sharlin 7y ago
- olivierduval 7y agoDo you know teh technical specs ? - 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
- woodrowbarlow 7y agogathered from the website and comments here: 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".
- itronitron 7y agocan anyone provide a reference for the artwork of Alice at the top of the page?

- JumpCrisscross 7y agoHow does this product change prospects for Magic Leap?
- yarg 7y agoThere's overlap between the potential client domains, but this doesn't encroach on the AR domain covered by products like Magic Leap. 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.
- jkoberg 7y ago> That’s why five years ago, my co-founder Alex and I started a company to prove that holographic displays were possible This is spam
- Filligree 7y agoIt's an ad, but it's the sort of ad I sincerely desire to see. C'mon, this is immensely cool.
- sosuke 7y agoSelf promotion sure but pretty darn cool too.
- dddddaviddddd 7y agoA startup putting out a technically interesting product seems relevant to me.
- ex3ndr 7y agoI have 4k version and it is very very bad. 4k is actually 4k/30 (number of angles). Pixels have the size of a fist.
- lux 7y agoBased on that, how do you think an 8k version would compare? Enough resolution, or still lacking?
- deleted 7y ago[deleted]
- ex3ndr 7y agoFor me it just have incorrect hm "angles" just like misplaced glasses or something like this. 8k won't help much since it is just bigger, not better PPI. It is just like decade old stereo camera like this: https://www.amazon.com/Fujifilm-FinePix-Real-Discontinued-Manufacturer/dp/B003ZHV70M https://www.amazon.com/Fujifilm-FinePix-Real-Discontinued-Ma....
- m3kw9 7y agoLooks like 3D inside a tv. It ain’t holographic unless it projects enough for you to touch thru it.
- Filligree 7y agoProjection is entirely impossible. The photon's path has to back-track through the device; this is true regardless of the type of device you're using to make it.
- Someone 7y agoI would think that the limitation is that, for both eyes, the ray from that eye through the simulated voxel has to intersect the screen. There are voxels in front of the screen for which that holds.
- yarg 7y agoOmni-directional beams of microscopic photon torpedoes could allow images to be projected in front of your hands.
- vilhelm_s 7y agoI think it can do both, the gif above the caption "It’s the truly futuristic, deeply immersive display we’ve always dreamed of" appears to project in front of the screen.
- Sharlin 7y agoReal holograms don't project from the surface either. Sci-fi "holograms" are a different thing. Please let's remember that holograms are an existing technology and have nothing do to with sci-fi 3D open-air projections.
- sgt101 7y agoSuddenly I see a consumer use case for Gb fttp.
- kempbellt 7y agoNot a hologram in the sci-fi sense, but still very cool. From what I gather, this is the same tech used in a 3DS - scaled up to an impressive scale.
- jFriedensreich 7y agoits not. lightfield techonology is a completely different beast from parallax stereoscopy.
- ex3ndr 7y agohow? it is just 30 layers of lenses on top of 8k monitor.
- Doxin 7y agoIt's the same thing in reverse. You can use a camera to capture a light field, and then a screen with a complementary lens to project out (roughly) the same light field. 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!
- vpribish 7y agolooks sketchy as fuck - it's a marketing piece put out by the company. Don't bother.
- burkaman 7y agoCan we change this URL to the original post at https://blog.lookingglassfactory.com/announcements/colossal-holograms/ https://blog.lookingglassfactory.com/announcements/colossal-...
- ouid 7y agoThere are two types of "this isn't a hologram" people in this thread. The first is the group of people that think holograms are the things in Star Trek. Those are not holograms, and neither is this.
- deleted 7y ago[deleted]
- mikeleung 7y agoThis reminds me of https://www.youtube.com/watch?v=Jd3-eiid-Uw https://www.youtube.com/watch?v=Jd3-eiid-Uw (2007) Johnny Lee's demonstration using head tracking with infrared led's and a wii remote to implement the same thing. Obviously that limits the effect to the individual's head being tracked, but its amazing its been 12 years since that demo and we're still trying to commercialize the same affect.
- ksaj 7y agoThat was a great video, and highly hackerific. "That would be a bit goofy" is an expression you don't hear very often these days.
- ericskiff 7y agoI have one of the smaller versions of the Looking Glass and it's genuinely like looking into the future. It's a remarkable thing to see live. My main complaint is the low resolution (4k divided into 45 layers). Bigger size and bigger resolution is a great step up here - I hope they get to continue in that direction!
- aaron695 7y agoA 3D hologram doesn't get you 3D medical records magically. 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.
