00:00:00.080 --> 00:00:08.160
looking glass factory started out with little 3d art pieces that were made by

00:00:05.440 --> 00:00:14.320
gluing together thin slices of acrylic to create a 3d object that's useful for

00:00:12.080 --> 00:00:19.119
you know visualizing an organ for a medical student or as like a you know

00:00:16.640 --> 00:00:24.400
kitschy desk ornament but that was never their endgame so in principle the goal

00:00:22.000 --> 00:00:30.640
was pretty simple instead of using ink to create static images they would use a

00:00:27.439 --> 00:00:34.000
field of light to create moving ones

00:00:30.640 --> 00:00:38.480
but in practice going from this

00:00:34.000 --> 00:00:40.480
to this was anything but straightforward

00:00:38.480 --> 00:00:44.320
our sponsor ridge wallet is the sleek way to keep wallet bulge down thanks to

00:00:42.239 --> 00:00:46.960
their compact frames and rfid blocking inner plates use offer code Linus to

save 10 and get free worldwide shipping

00:00:57.680 --> 00:01:03.920
like any stereoscopic 3d display a looking glass needs to show an image

00:01:01.840 --> 00:01:08.000
from at least two perspectives to create the sensation of depth in the movie

00:01:06.159 --> 00:01:12.240
theater this is done using polarized projectors and lenses and in a vr

00:01:10.159 --> 00:01:16.799
headset it's done by physically separating the images that are sent into

00:01:14.560 --> 00:01:21.920
each eye but both of these techniques have limitations a 3d film for example

00:01:19.680 --> 00:01:26.320
can only be viewed from a single vantage point you can't you know move your head

00:01:24.240 --> 00:01:30.720
around to see a sticker on buzz lightyear's shoulder and a vr headset

00:01:29.040 --> 00:01:34.880
well it's not easily shared with a friend or a colleague

00:01:32.400 --> 00:01:40.400
looking glasses technology by contrast allows a group of people as many as can

00:01:37.759 --> 00:01:46.240
fit in about a 50 degree cone coming out of the display to view and interact with

00:01:43.280 --> 00:01:51.759
3d objects and renders in real time it requires no eyewear and allows each

00:01:49.360 --> 00:01:57.040
user's perspective to individually change as they move their head around

00:01:54.399 --> 00:02:01.360
within the viewing cone so you guys can actually see

00:01:58.320 --> 00:02:02.799
this aspect of the effect on camera even

00:02:01.360 --> 00:02:07.119
it's it's super trippy it's like i'm holding

00:02:05.200 --> 00:02:10.879
this frog right now don't worry i'll be careful with it and whether we're

00:02:08.560 --> 00:02:15.680
looking at the two and a half k or the 4k dev kit the most striking thing about

00:02:13.520 --> 00:02:20.959
the looking glass is how real the objects inside appear to be

00:02:18.480 --> 00:02:26.000
because here's the thing on a 2d display every pixel shines with a given

00:02:23.040 --> 00:02:31.440
intensity and color but through a looking glass the light also has

00:02:28.680 --> 00:02:38.000
directionality to it so this sophisticated slab of optics actually

00:02:35.440 --> 00:02:45.440
splits the otherwise totally normal display underneath into 45 different

00:02:41.920 --> 00:02:49.120
perspectives that means that as you move

00:02:45.440 --> 00:02:52.239
left and right each eye is grabbing the

00:02:49.120 --> 00:02:55.200
image from a different point of view and

00:02:52.239 --> 00:03:00.400
the light reflections off of the objects in the looking glass actually change

00:02:57.680 --> 00:03:07.599
realistically and again that is on a per eye basis this comes at a significant

00:03:03.840 --> 00:03:10.159
cost to image fineness because only one

00:03:07.599 --> 00:03:15.120
out of every 45 pixels of the display can be allocated to each perspective

00:03:13.120 --> 00:03:20.640
but it works quite a bit better than you'd think because the 3d effect and

00:03:18.159 --> 00:03:26.319
the better lighting realism increases the perceived resolution and so does the

00:03:23.840 --> 00:03:33.040
way that looking glass actually splits each pixel into the individual rgnb

00:03:30.000 --> 00:03:35.200
subpixels before mapping them to the

00:03:33.040 --> 00:03:39.120
various perspectives as you guys can imagine the processing involved in

00:03:37.040 --> 00:03:44.720
rendering a scene even a simple one like this algae demo that was created in

00:03:40.959 --> 00:03:47.440
unity from 45 different perspectives is

00:03:44.720 --> 00:03:53.760
not trivial and the gtx 1050 in this gaming laptop is working pretty hard and

00:03:50.159 --> 00:03:55.760
we're still not getting a locked 60fps

00:03:53.760 --> 00:03:58.720
so these experiences are pretty good but

00:03:57.519 --> 00:04:04.879
looking glass even though they've actually shipped thousands of these dev kits hasn't considered either of them

00:04:02.480 --> 00:04:09.680
good enough to slap their company name on it and fully productize it

00:04:07.200 --> 00:04:14.239
that comes in a moment this

00:04:11.200 --> 00:04:18.079
is the looking glass 8k and this thing

00:04:14.239 --> 00:04:21.680
absolutely has to be seen to be believed

00:04:18.079 --> 00:04:24.400
now as before it takes 45 pixels to

00:04:21.680 --> 00:04:30.160
create a single pixel from all 45 perspectives but guys when you're

00:04:26.800 --> 00:04:31.680
working with 33 million pixels instead

00:04:30.160 --> 00:04:37.120
of just 8 million it gives you a ton of different benefits

00:04:35.120 --> 00:04:41.919
first and foremost of course is that you get a much finer image i mean the dead

00:04:39.360 --> 00:04:48.479
kits are impressive but when i walked into this room my eyes just about popped

00:04:45.360 --> 00:04:51.120
right out of their sockets this 3d model

00:04:48.479 --> 00:04:57.759
of a person's face is crazy lifelike and once we swapped it

00:04:54.639 --> 00:04:59.919
out for a 3d scan of a real person

00:04:57.759 --> 00:05:05.680
removing some of the uncanny valley effect it got even more convincing

00:05:03.680 --> 00:05:12.080
another benefit is that they actually needed far fewer optical tricks in order

00:05:08.960 --> 00:05:14.639
to create the 3d effect so this slab on

00:05:12.080 --> 00:05:20.560
the front of the display is much thinner than the dev kits see a big chunk of

00:05:16.960 --> 00:05:23.360
this was actually used to pull the image

00:05:20.560 --> 00:05:28.000
up away from the actual display to deepen the focal point which is the part

00:05:25.840 --> 00:05:32.639
of the image that appears to be in focus to your eyes on the 8k

00:05:30.160 --> 00:05:37.199
that's no longer necessary and again thanks to the additional resolution it's

00:05:34.639 --> 00:05:42.720
possible to have objects sink into the display and even appear to be

00:05:39.919 --> 00:05:46.880
popping out of it with much much greater clarity like this

00:05:44.720 --> 00:05:51.680
you can't really capture it on camera but in person the effect is

00:05:49.360 --> 00:05:55.520
shocking and impressive and what's really cool about it is it's

00:05:53.039 --> 00:05:59.919
surprisingly comfortable to look at in spite of the fact that i showed up here

00:05:57.680 --> 00:06:03.440
jet lagged and with a bit of a headache i didn't experience

00:06:01.440 --> 00:06:08.319
any of the discomfort that i feel with something like a nintendo 3ds or the

00:06:06.000 --> 00:06:13.199
nausea that you experience when watching vr content that's not at a very high

00:06:10.560 --> 00:06:18.160
refresh rate and during this demo we also got a really good look at the

00:06:15.120 --> 00:06:20.160
appearance of apps before they get moved

00:06:18.160 --> 00:06:27.039
over to the looking glass so i was able to get up close and see some of the RGB

00:06:24.240 --> 00:06:32.720
subpixels that are clearly in the wrong place like a very bright green pixel

00:06:30.319 --> 00:06:36.000
that's sitting in a dark mountain range that must need to be remapped somewhere

00:06:35.199 --> 00:06:40.960
else so this whole process of

00:06:38.479 --> 00:06:46.800
remapping subpixels needs to be done extremely accurately and every finished

00:06:44.400 --> 00:06:52.560
display actually needs to be calibrated to account for tiny discrepancies in the

00:06:50.000 --> 00:06:58.160
manufacturing tolerance of the optics so that information then gets stored in the

00:06:55.120 --> 00:07:00.319
display kind of like a digital

00:06:58.160 --> 00:07:04.479
fingerprint the rest of the processing though is done by the pc so believe it

00:07:03.599 --> 00:07:10.960
or not most of the engineering work that gets done here is actually software

00:07:08.240 --> 00:07:15.120
engineering they've got sdks for unity and unreal engine they've created useful

00:07:12.960 --> 00:07:20.080
little tools like a 3d mouse cursor that allows you to use a simple regular mouse

00:07:17.520 --> 00:07:24.479
to select or focus on 3d objects with a 2d input device and they've got a 3d

00:07:22.319 --> 00:07:29.440
model importer so that anyone can grab a model out of a repository and view it

00:07:27.360 --> 00:07:32.560
and of course many of the demos that they ran

00:07:30.400 --> 00:07:37.360
focused on what they expect people to actually do with these things in the

00:07:34.479 --> 00:07:42.400
real world medical applications both for students and practicing doctors are

00:07:39.599 --> 00:07:46.479
basically limitless and i was blown away by how

00:07:43.599 --> 00:07:51.440
different it was experiencing this tour of the house through a looking glass

00:07:49.520 --> 00:07:56.879
compared to just looking at it in 2d like i really felt like i had a great

00:07:54.160 --> 00:08:03.039
sense of the scale of the space to walk around in and that's without putting on

00:08:00.000 --> 00:08:05.440
a headset or even glasses i mean

00:08:03.039 --> 00:08:09.520
architectural firms design firms they're going to be all over that because you

00:08:07.280 --> 00:08:15.840
can sit with the client and look at it and interact with it without you know

00:08:12.240 --> 00:08:17.759
any weirdness as before it's 45

00:08:15.840 --> 00:08:22.479
rendering passes for every one of these demos at 8k

00:08:20.080 --> 00:08:26.960
so as you guys can probably imagine this one ain't running on a laptop and if the

00:08:25.440 --> 00:08:32.159
temperature in this room is anything to go by the rtx 2080 ti in this system is

00:08:30.240 --> 00:08:36.919
working pretty hard so hard i even had to remove my LTT

00:08:35.279 --> 00:08:40.320
stealth hoodie lttstore.com

00:08:38.640 --> 00:08:44.720
two of the most mind-blowing demos for me personally were this render of some

00:08:42.399 --> 00:08:49.440
cartography tools where as you move your head around the magnifying glass here

00:08:47.200 --> 00:08:53.680
actually works exactly the way you'd expect and

00:08:51.200 --> 00:08:58.959
this recording of one of looking glass's developers that was taken on an azure

00:08:55.680 --> 00:09:01.440
connect so you can see there's actual

00:08:58.959 --> 00:09:06.480
depth to her face and you guys might not realize this but odds are if you have a

00:09:04.000 --> 00:09:11.279
recent model smartphone you are carrying a depth sensing camera around in your

00:09:08.720 --> 00:09:17.200
pocket so with display technology like this and depth sensing cameras we're

00:09:14.160 --> 00:09:20.399
talking real time holographic video

00:09:17.200 --> 00:09:22.240
calling that's crazy now there are some

00:09:20.399 --> 00:09:25.760
blind spots in this image because it was taken with a single camera from a single

00:09:24.560 --> 00:09:31.120
perspective but that's something that could be overcome pretty easily by just adding a

00:09:29.440 --> 00:09:36.320
second camera and a little bit of real-time software stitching

00:09:33.279 --> 00:09:38.800
not crazy like guys the future is now

00:09:36.320 --> 00:09:44.160
now thing is to own the future you're gonna have to dig pretty deep because

00:09:40.720 --> 00:09:46.560
even the 4k developer kit is three grand

00:09:44.160 --> 00:09:50.720
and the price for the 8k looking glass is uh

00:09:47.760 --> 00:09:53.760
contact us so basically if you have to ask

00:09:51.839 --> 00:09:57.440
you probably can't afford it so unless you've got a commercial reason for

00:09:55.360 --> 00:10:01.200
buying one your best bet is probably to try to find a demo to check out because

00:09:59.440 --> 00:10:05.839
it is worth seeing in person it sounds like the easiest place to do that is

00:10:03.120 --> 00:10:12.320
going to be ces 2020. this video is brought to you by drop.com the cost gmr
