Hands-On with a Volumetric 3D Display! 

Please learn to mix your audio into both channels, its getting annoying now

Why isn't the camera moving around the 3D display to show it's depth?!

Ok, I'm disliking every video with bad audio mixing, I suggest everybody does the same, guess that's the only way for us to have an impact on future quality of the videos.

What is wrong with the audio lately?

It's making me fucking dizzy with headphones on, who the fuck in there thought this was actually plasant, ffs? I don't wanna be that guy complaining about not being pleased by free content, but this is beyond ridiculous.

My right ear is really enjoying this video. Left ear... Not so much.

This is cool, the main issue I can see is the difference between layered light and layered matte surfaces. The layered light will intensify with each new layer that overlaps it. I'm assuming thats why they are limiting the number of slices and the brightness of the display (it looks quite dim). The layered matte surface looks much better with the 3D frog and man as it occludes the layer behind and relies on ambient light to reveal it, like a real object in the room. So maybe the layers need to be some form of liquid crystal display that does not emanate light, then are lit externally (think gameboy display with the top light LCD display).

Man just imagine how primitive this will look in the future...

That flower demo looks cool, cant wait to see where this leads.

I echo what others have said this audio format isnt working for interviews

your sound guy is FIRED

Close your eyes and is almost like George Takei is narrating this :-P

SIMONE GIERTZ IS MY LIFE I LOVE ALL OF HER CREATIONS AND I LOVE THIS CHANNEL SO MUCH KEEP BEING AMAZING

Pretty cool! Would be very interesting to see when it develops more.. bigger screen.. or cube? higher res, etc.. With progression of this technology, I can see it getting there. Maybe it's hard to show the real 3D effect of this device, but I am also curious how it looks like when you walk around looking at it.. I feel from what we've seen, it's may only be visible from the front and certain angles off the front image plane.. can you see it all around?.. You guys seem to be viewing from the back (maybe a reverse or inverted 3D image of what you'd see from the front?).. so perhaps front and back angles only.. the side I think would disappear, possibly. And, I believe you'd probably need to use and see this in at least a dimly lit room, if not as dark as possible. Because it's made of light on a transparency, the images displayed will probably always be at least semi-translucent and never completelyt opaque... it would be interesting if there was a way to get the pixel density and intensity high enough so the objects viewed could look more solid rather than ghosted. This is just another from of virtual reality. Very cool stuff, but unfortunately we're still limited by the fact there must be a medium between us and the virtual projection.. Either with a headset or goggles as we've seen a lot of variations on already these days, or if it's "physically" in our world, it still needs a medium to project and be viewable. It's hard to imagine there will ever be a day that we will get true 3D virtual reality holographic projection like what we've seen in Star Trek's Holodeck.. where you don't need a head set or piece of plastic to project and virtual object into or through, but have it materialize in thin air..

I worked on 3-D volumetric displays for the US Navy in 1996. I’m glad to see the technology has come so far since then.

Super cool that it started with that prototype with blinking lights.

This is really great and all but WHAT IS UP with the freaking stereo? I can't even focus on what your saying because the audio keeps switching between ears.... -_-

Nicely done! What a great solution! Mind blowing possibilities!

Pretty cool. It will be interesting to see where this technology progresses. Thanks guys!

Very nice idea for a 3D display

Anyone else only get norm in one ear and the other dude in the other? It made me want to KMS honestly, it drove me insane.

You guys should interview the folks working on compressive lightfield displays (I think that's what's called; they use 3 layers of screen and a tomography algorithm to produce full parallax lightfields).

I quite enjoy the audio. 7.1 headphones are really cool to listen to stuff like this on.

Audio aside, this looks much more interesting than the first time I saw an ad for it on facebook or whatever. Not really a consumer product, but not gimmicky-buzzword marketing like I expected, either.

would make a cool virtual fish tank

Hope you guys can get audio QC back into your pipeline. Sad to see the 2 most recent videos both have not been corrected to convert the mono L/R source to stereo. Love the channel, support what you do as a premium paid subscriber, and hope these issues become a thing of the past (again)

For the people complaining about the audio... it's just in stereo off the mic. You're specifically requesting mono I guess?

tested is life

I guarantee these will be common in military applications within 10 years, home market a couple after that. great technology

Man what if they set it up so that you had 3 projectors each dedicated to different focuses like 1 projector solely for foreground, 1 for the middle and 1 for the backround

I would love to have the next generation of this with higher resolution for working in CAD when I don't want to wear a headset, but the 2D screen just can't cut it.

Great tech demo :)

My right ear really enjoyed norm

My left nostril is jealous

incredible!

Interesting. Images are a bit washed out, though, because they come from a projector. And quite low res. So it's nice that's a step forward, but I really want to see something (that would be waaaay more expensive) like a stack of transparent OLED screens, each screen on the stack behind the previous having to compensate for light and color, of course. The flower demo is really neat!

Does anyone know if you can order those 3d prints in cubes? They look kinda cool!

Closer to holograms everyday. I'm hoping it will be like guardians of the Galaxy type where the hologram looks more like moving models.

I feel like these guys are going to be the first develop holograms. They are getting closer. Really though, the product itself could just be a tv without a 4D screen. The product itself already is included without having to wear one.

Love the audio. Not a lot of RU-vid channels include 7.1 Dolby surround sound. It sounds so crisp. You can tell where they are in the room. I really love it.

It somehow reminds me of the first tv

Hmm. A very nifty concept, to be sure, but at this point it seems more of a novelty than a ready to market product. The audio here is distracting. It reminds me of old records from when stereo first became available, and they really wanted to show it off, hard-panning things to the left or right. Also, I had to replay at 5:08 to make sure someone wasn't banging on my ceiling. Maybe I'm missing the point, and the audio was an attempt to create 3D sound to go with the 3D display? :)

We got the holograms bois, what's next on the list.

this is amazing! could be huge, could be a game changer. ive been saying for a while that the next big step forward in technology will be something other than a conventional screen. this might be it.

Wow just wow...

I'd love to play Captain Toads Treasure Tracker with a volumetric display, it would be so awesome.

hm how about stacking oled up? the visibility could be an issue

the audio is good, it's just that panning to the extreme left and right is probably not the way to do it, maybe ease up on the panning a little bit...less is more

I wish someone would revisit this concept on a larger scale, maybe someone who could do a collaboration with Linus tech tips to make a 4k, 120Hz 20 slices and game compatible video conversion software for everyday use

When will you do a video with Adam?

i want one of these the size of a coffee table and have it be super high rez..

the problem is that with projection the darkest color you can get is the darkest color on the screen. So black will turn out transparent

I had no idea the audio was so bad for most headphone users. I personally have the Artemis G633, with Tru Dolby 7.1 turned on, so the reverb just made the 2.1 channel audio on this video sound fantastic and more immersive. However, I can understand the pain you guys are going through. Before I purchased the G633, I had broken my G35 headphones and was forced to listen through my ATH-M50X for a week, it gave me a headache listening to an audio track on a single ear. I hope they fix this soon, you guys should try tweeting about it. However, I do enjoy 2 channels of microphones, but they should run the 2 channels through DTS surround or Dolby Digital compression at the least, that way the audio actually sounds more immersive, while giving our ears more equality.

nice, so we're back to the Apple 2 level display? :) I'll check back in 10 years

I actually quite liked the audio, it sounds more 3D. Used speakers set at about an arm span apart.

this would be great for architecture community we would love to have that for clients to see the 3D model and interact with it as well collectively as a group instead of VR Goggle's

clyp.it/dixddmvx MONO version of the sound, mute the video and play this in the background instead. Vastly improves the quality of sound for headphones users.

I'm listening to this with a 7.1 surround headset and it sounds amazing. The users here who are complaining about the audio might be using a 2.0 setup. If this is why some have bad audio and I don't, then a feature for setting audio to 2.0, would be very helpful, and perhaps don't post videos yet with 7.1 if the platform does not allow users to switch back and forth. There was a sound, think he is putting down the iPad off camera, @5:08, and I jumped because it sounded just like it happened in the room I'm sitting in. 7.1 FTW, but still, an option to switch to a 2.0 track might be useful.

Or you could just wear a VR headset with much higher resolution. This is cool but I don't know if it'll ever overtake VR. I could see it being used in stores and such. Just not in the home. Not to mention they'll also be racing AR. If everyone could wear an AR headset you get this much easier.

This Leap Motion thing is also fucking interesting. They should use this for VR

When it comes to conversations i much prefer mono sound, i find the stereo interview to be quite unpleasant to listen to.

Impressive

Definitely makes you wonder how we will be interacting with technology in the future.

As primitive as this sounds wouldn't it be cool to play the original vector graphics Star Wars game on this system.

Did these guys miss the memo on transparent LCD/OLED displays? Then again, this approach could be cheaper than just having a bunch of those.

Sounds like in-camera audio for norm.

but can I get a custom one which is 2m cubed?

My head hurts. WHAT DID YOU DO TO THE SOUND

I'm interested that they are doing 1080 (2million pixels), when 4k (8 million pixels) is nearly commonly available

it reminds be of the early days of computer games and raytracing. and look at where we are now.

Maybe a 4k projector would make this a lot better?

Finally future television is born.

are you guys trying some binaural microphone stuff?

nice

Am I the only one who's nostalgic for the days where the barrier to entry for art wasn't a degree in optics or computer science but a paintbrush, or a simple camera?

In today's market the Consumer Version needs to be (at least) 1080p, add that to 20 planes. Which would require a source resolution 21,600 x 38,400 or essentially 38K.... RIP

I listened to it through a one ear bluetooth headset and it seems it mixes the channels together. Because while I heard it as normal mono. There was this awkward dead silence between the speakings. But about panning. This is kind of a beginners phase normally. Hard panning the left and right channels and removing all noise and roomtone... But Tested has been doing videos for years. Tested should know how to mix a non-distracting track right? There's a simple rule that is followed by practically all sound mixers of Hollywood 5.1 movies... if the speaker is in frame... keep the sound in center. Actually. If not properly motivated to do otherwise. Always keep speech in the center. To test this. Unplug your center from your 5.1 system and see how much speech you get from the front left and right. Yes there are times when a hard pan is preferable. But the vast majority of speech is served best with a center mix. Even trickery like mid/side mixing is mono friendly while retaining a stereo feel. Not convinced? Well the video was about a potentially revolutionary process to get hologram like volumetric video. And what do the comments go on and on about? The vast majority?

I think it would be fun to play atari or 3d games on it.

So essentially for a 10 plain volumetric display, to achieve a 1080p image you would need a 19K source? Source = Output Height x Planes(n) ? Even if Moore's Law did apply here based on this prototype this will take 2 to 5 years to be possible? Nice.

Theres been a couple of new videos where you mix mic audio based on position, but it waaay to much. really uncomfortable to listen to, especially with headphones.

I would love to play top down strategy rts's and whatnot on this. Directing troops around a 3d board would be great. Maybe it's just me but I just think of a ton of board games on crack with this thing :p

Oh and the audio aside... please someone make a Super Glove Ball port for this!

Now I thinking.. Apple new headset will have something similar? Feel reality which was long ago..

Sure!

When filming 3d stuff with a 2d camera, remember to move the camera side to side.

How this works please ?

ugh im nearly deaf in my right ear and this plays right into that one only with headphones

They should start a kickstarter for a 3D holographic fish tank with a motion sensor so when putting your hands up to it like your feeding the fish or whatever, they will react.Lets say you can upload different fish or mini sharks and stingrays via wifi or bluetooth LOL I would buy it. I do not like changing fish tank water its to much and I bet a lot of people would agree.

Add a glove so it will press preasure to your hand so you are like aaccualy touching it

Maybe a modelling product but its a long way off it has to be better than a physical model and as cheap. If it does get that detailed it could cross into the Sims, Age of Empires doll house type gaming or museums.

Get your audio together!

x1000 that resolution would look good

Thank god my headset has an mono/stereo switch :)

HEY AQUI TIENEN UNA IDEA MILLONARIA HAGAN DOS DE MODIFIQUE-LO ACAECIENDOLO MUCHO MAS PEQUEÑO PARA LENTES DE REALIDAD AUMENTADA

Amazing video, but why are you using a directional mic? Or a separate mic for each speaker? Through external speakers this is pushing it, but with headphones it's unbearable! I've been composing music for years, and even with stereo-widening on maximum TWICE, it's easier to listen to. Please... mono would be better.

1:16 He mentions pixels but a true volumetric display would use voxels.

Does it look sharper in real life?

Omg!! I came up with an idea that's identical to this, I think my idea works better of course, totally not an engineer! I think I cried a little

You have a 3 denial monitor but you record it parallel to the camera... Showing off 3d to the best of 2ds ability... You could have tilted it
