1
00:00:00,080 --> 00:00:08,160
looking glass factory started out with little 3d art pieces that were made by

2
00:00:05,440 --> 00:00:14,320
gluing together thin slices of acrylic to create a 3d object that's useful for

3
00:00:12,080 --> 00:00:19,119
you know visualizing an organ for a medical student or as like a you know

4
00:00:16,640 --> 00:00:24,400
kitschy desk ornament but that was never their endgame so in principle the goal

5
00:00:22,000 --> 00:00:30,640
was pretty simple instead of using ink to create static images they would use a

6
00:00:27,439 --> 00:00:34,000
field of light to create moving ones

7
00:00:30,640 --> 00:00:38,480
but in practice going from this

8
00:00:34,000 --> 00:00:40,480
to this was anything but straightforward

9
00:00:38,480 --> 00:00:44,320
our sponsor ridge wallet is the sleek way to keep wallet bulge down thanks to

10
00:00:42,239 --> 00:00:46,960
their compact frames and rfid blocking inner plates use offer code Linus to

11
00:00:46,000 --> 00:00:57,680
save 10 and get free worldwide shipping

12
00:00:57,680 --> 00:01:03,920
like any stereoscopic 3d display a looking glass needs to show an image

13
00:01:01,840 --> 00:01:08,000
from at least two perspectives to create the sensation of depth in the movie

14
00:01:06,159 --> 00:01:12,240
theater this is done using polarized projectors and lenses and in a vr

15
00:01:10,159 --> 00:01:16,799
headset it's done by physically separating the images that are sent into

16
00:01:14,560 --> 00:01:21,920
each eye but both of these techniques have limitations a 3d film for example

17
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

18
00:01:24,240 --> 00:01:30,720
around to see a sticker on buzz lightyear's shoulder and a vr headset

19
00:01:29,040 --> 00:01:34,880
well it's not easily shared with a friend or a colleague

20
00:01:32,400 --> 00:01:40,400
looking glasses technology by contrast allows a group of people as many as can

21
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

22
00:01:43,280 --> 00:01:51,759
3d objects and renders in real time it requires no eyewear and allows each

23
00:01:49,360 --> 00:01:57,040
user's perspective to individually change as they move their head around

24
00:01:54,399 --> 00:02:01,360
within the viewing cone so you guys can actually see

25
00:01:58,320 --> 00:02:02,799
this aspect of the effect on camera even

26
00:02:01,360 --> 00:02:07,119
it's it's super trippy it's like i'm holding

27
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

28
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

29
00:02:13,520 --> 00:02:20,959
the looking glass is how real the objects inside appear to be

30
00:02:18,480 --> 00:02:26,000
because here's the thing on a 2d display every pixel shines with a given

31
00:02:23,040 --> 00:02:31,440
intensity and color but through a looking glass the light also has

32
00:02:28,680 --> 00:02:38,000
directionality to it so this sophisticated slab of optics actually

33
00:02:35,440 --> 00:02:45,440
splits the otherwise totally normal display underneath into 45 different

34
00:02:41,920 --> 00:02:49,120
perspectives that means that as you move

35
00:02:45,440 --> 00:02:52,239
left and right each eye is grabbing the

36
00:02:49,120 --> 00:02:55,200
image from a different point of view and

37
00:02:52,239 --> 00:03:00,400
the light reflections off of the objects in the looking glass actually change

38
00:02:57,680 --> 00:03:07,599
realistically and again that is on a per eye basis this comes at a significant

39
00:03:03,840 --> 00:03:10,159
cost to image fineness because only one

40
00:03:07,599 --> 00:03:15,120
out of every 45 pixels of the display can be allocated to each perspective

41
00:03:13,120 --> 00:03:20,640
but it works quite a bit better than you'd think because the 3d effect and

42
00:03:18,159 --> 00:03:26,319
the better lighting realism increases the perceived resolution and so does the

43
00:03:23,840 --> 00:03:33,040
way that looking glass actually splits each pixel into the individual rgnb

44
00:03:30,000 --> 00:03:35,200
subpixels before mapping them to the

45
00:03:33,040 --> 00:03:39,120
various perspectives as you guys can imagine the processing involved in

46
00:03:37,040 --> 00:03:44,720
rendering a scene even a simple one like this algae demo that was created in

47
00:03:40,959 --> 00:03:47,440
unity from 45 different perspectives is

48
00:03:44,720 --> 00:03:53,760
not trivial and the gtx 1050 in this gaming laptop is working pretty hard and

49
00:03:50,159 --> 00:03:55,760
we're still not getting a locked 60fps

50
00:03:53,760 --> 00:03:58,720
so these experiences are pretty good but

51
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

52
00:04:02,480 --> 00:04:09,680
good enough to slap their company name on it and fully productize it

53
00:04:07,200 --> 00:04:14,239
that comes in a moment this

54
00:04:11,200 --> 00:04:18,079
is the looking glass 8k and this thing

55
00:04:14,239 --> 00:04:21,680
absolutely has to be seen to be believed

56
00:04:18,079 --> 00:04:24,400
now as before it takes 45 pixels to

57
00:04:21,680 --> 00:04:30,160
create a single pixel from all 45 perspectives but guys when you're

58
00:04:26,800 --> 00:04:31,680
working with 33 million pixels instead

59
00:04:30,160 --> 00:04:37,120
of just 8 million it gives you a ton of different benefits

60
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

61
00:04:39,360 --> 00:04:48,479
kits are impressive but when i walked into this room my eyes just about popped

62
00:04:45,360 --> 00:04:51,120
right out of their sockets this 3d model

63
00:04:48,479 --> 00:04:57,759
of a person's face is crazy lifelike and once we swapped it

64
00:04:54,639 --> 00:04:59,919
out for a 3d scan of a real person

65
00:04:57,759 --> 00:05:05,680
removing some of the uncanny valley effect it got even more convincing

66
00:05:03,680 --> 00:05:12,080
another benefit is that they actually needed far fewer optical tricks in order

67
00:05:08,960 --> 00:05:14,639
to create the 3d effect so this slab on

68
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

69
00:05:16,960 --> 00:05:23,360
this was actually used to pull the image

70
00:05:20,560 --> 00:05:28,000
up away from the actual display to deepen the focal point which is the part

71
00:05:25,840 --> 00:05:32,639
of the image that appears to be in focus to your eyes on the 8k

72
00:05:30,160 --> 00:05:37,199
that's no longer necessary and again thanks to the additional resolution it's

73
00:05:34,639 --> 00:05:42,720
possible to have objects sink into the display and even appear to be

74
00:05:39,919 --> 00:05:46,880
popping out of it with much much greater clarity like this

75
00:05:44,720 --> 00:05:51,680
you can't really capture it on camera but in person the effect is

76
00:05:49,360 --> 00:05:55,520
shocking and impressive and what's really cool about it is it's

77
00:05:53,039 --> 00:05:59,919
surprisingly comfortable to look at in spite of the fact that i showed up here

78
00:05:57,680 --> 00:06:03,440
jet lagged and with a bit of a headache i didn't experience

79
00:06:01,440 --> 00:06:08,319
any of the discomfort that i feel with something like a nintendo 3ds or the

80
00:06:06,000 --> 00:06:13,199
nausea that you experience when watching vr content that's not at a very high

81
00:06:10,560 --> 00:06:18,160
refresh rate and during this demo we also got a really good look at the

82
00:06:15,120 --> 00:06:20,160
appearance of apps before they get moved

83
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

84
00:06:24,240 --> 00:06:32,720
subpixels that are clearly in the wrong place like a very bright green pixel

85
00:06:30,319 --> 00:06:36,000
that's sitting in a dark mountain range that must need to be remapped somewhere

86
00:06:35,199 --> 00:06:40,960
else so this whole process of

87
00:06:38,479 --> 00:06:46,800
remapping subpixels needs to be done extremely accurately and every finished

88
00:06:44,400 --> 00:06:52,560
display actually needs to be calibrated to account for tiny discrepancies in the

89
00:06:50,000 --> 00:06:58,160
manufacturing tolerance of the optics so that information then gets stored in the

90
00:06:55,120 --> 00:07:00,319
display kind of like a digital

91
00:06:58,160 --> 00:07:04,479
fingerprint the rest of the processing though is done by the pc so believe it

92
00:07:03,599 --> 00:07:10,960
or not most of the engineering work that gets done here is actually software

93
00:07:08,240 --> 00:07:15,120
engineering they've got sdks for unity and unreal engine they've created useful

94
00:07:12,960 --> 00:07:20,080
little tools like a 3d mouse cursor that allows you to use a simple regular mouse

95
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

96
00:07:22,319 --> 00:07:29,440
model importer so that anyone can grab a model out of a repository and view it

97
00:07:27,360 --> 00:07:32,560
and of course many of the demos that they ran

98
00:07:30,400 --> 00:07:37,360
focused on what they expect people to actually do with these things in the

99
00:07:34,479 --> 00:07:42,400
real world medical applications both for students and practicing doctors are

100
00:07:39,599 --> 00:07:46,479
basically limitless and i was blown away by how

101
00:07:43,599 --> 00:07:51,440
different it was experiencing this tour of the house through a looking glass

102
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

103
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

104
00:08:00,000 --> 00:08:05,440
a headset or even glasses i mean

105
00:08:03,039 --> 00:08:09,520
architectural firms design firms they're going to be all over that because you

106
00:08:07,280 --> 00:08:15,840
can sit with the client and look at it and interact with it without you know

107
00:08:12,240 --> 00:08:17,759
any weirdness as before it's 45

108
00:08:15,840 --> 00:08:22,479
rendering passes for every one of these demos at 8k

109
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

110
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

111
00:08:30,240 --> 00:08:36,919
working pretty hard so hard i even had to remove my LTT

112
00:08:35,279 --> 00:08:40,320
stealth hoodie lttstore.com

113
00:08:38,640 --> 00:08:44,720
two of the most mind-blowing demos for me personally were this render of some

114
00:08:42,399 --> 00:08:49,440
cartography tools where as you move your head around the magnifying glass here

115
00:08:47,200 --> 00:08:53,680
actually works exactly the way you'd expect and

116
00:08:51,200 --> 00:08:58,959
this recording of one of looking glass's developers that was taken on an azure

117
00:08:55,680 --> 00:09:01,440
connect so you can see there's actual

118
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

119
00:09:04,000 --> 00:09:11,279
recent model smartphone you are carrying a depth sensing camera around in your

120
00:09:08,720 --> 00:09:17,200
pocket so with display technology like this and depth sensing cameras we're

121
00:09:14,160 --> 00:09:20,399
talking real time holographic video

122
00:09:17,200 --> 00:09:22,240
calling that's crazy now there are some

123
00:09:20,399 --> 00:09:25,760
blind spots in this image because it was taken with a single camera from a single

124
00:09:24,560 --> 00:09:31,120
perspective but that's something that could be overcome pretty easily by just adding a

125
00:09:29,440 --> 00:09:36,320
second camera and a little bit of real-time software stitching

126
00:09:33,279 --> 00:09:38,800
not crazy like guys the future is now

127
00:09:36,320 --> 00:09:44,160
now thing is to own the future you're gonna have to dig pretty deep because

128
00:09:40,720 --> 00:09:46,560
even the 4k developer kit is three grand

129
00:09:44,160 --> 00:09:50,720
and the price for the 8k looking glass is uh

130
00:09:47,760 --> 00:09:53,760
contact us so basically if you have to ask

131
00:09:51,839 --> 00:09:57,440
you probably can't afford it so unless you've got a commercial reason for

132
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

133
00:09:59,440 --> 00:10:05,839
it is worth seeing in person it sounds like the easiest place to do that is

134
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
