1
00:00:10,210 --> 00:00:16,120
us so thanks a lot for coming along
is i'm right am reusing some slides

2
00:00:16,120 --> 00:00:16,700
i gave

3
00:00:17,980 --> 00:00:23,210
values for different presentation an internal
sort of some it we have intel i hadn't

4
00:00:23,210 --> 00:00:28,650
planned ahead to do this talk what they opportunity
came up since vision a pistol

5
00:00:28,650 --> 00:00:30,860
guess today to present this is

6
00:00:31,900 --> 00:00:40,020
apologies about the branding and they didn't tell
confidential as ensemble size you know that

7
00:00:42,490 --> 00:00:43,150
okay so

8
00:00:44,370 --> 00:00:49,120
my name's rubber private can i work for yet
entails open source technology centre in

9
00:00:49,120 --> 00:00:49,940
london

10
00:00:50,640 --> 00:00:55,950
on a graphics engine enjoyed graphics for a long time

11
00:00:56,590 --> 00:01:01,490
and just have the opportunity to work on a number
of players in the graphics

12
00:01:01,490 --> 00:01:04,070
to a linux ideas

13
00:01:04,740 --> 00:01:10,720
one of the first companies i work so was imagination
technologies right at the option

14
00:01:10,720 --> 00:01:12,620
introduce silicon enabling

15
00:01:13,280 --> 00:01:18,270
some about where and work through the open
G L driver and some of the

16
00:01:18,270 --> 00:01:21,230
kernel driver and that kind of low level work and

17
00:01:21,850 --> 00:01:22,890
and i moved to

18
00:01:24,120 --> 00:01:29,540
sort of a small company product and swear
we'd it's discarded toolkit and gain some

19
00:01:29,540 --> 00:01:37,140
experience with high level you are technologies
and through into stress composites as and

20
00:01:37,580 --> 00:01:38,610
or you can

21
00:01:39,150 --> 00:01:41,710
the work in firefox

22
00:01:42,570 --> 00:01:44,480
but so

23
00:01:45,680 --> 00:01:46,720
as well as having this

24
00:01:47,120 --> 00:01:48,250
passion for graphics

25
00:01:48,740 --> 00:01:55,020
i've been fortunate to work in an office
which is got cut indicated design is

26
00:01:55,020 --> 00:01:59,950
visual design is interaction design
as well as engine is the have been

27
00:02:00,430 --> 00:02:04,200
involved in creating applications the design by these guys

28
00:02:04,730 --> 00:02:10,300
and so i've seen the process by which
we come up with ideas and we

29
00:02:10,300 --> 00:02:16,270
create applications and so i hope they have
some insight into where that process is

30
00:02:16,270 --> 00:02:18,910
not as effective as i think it could be

31
00:02:20,080 --> 00:02:20,630
and

32
00:02:21,640 --> 00:02:27,350
so i'm here to talk about this project
who rate which i started about

33
00:02:27,930 --> 00:02:31,970
that you're going to be working on sort
of part time which is this is

34
00:02:31,970 --> 00:02:33,070
owed sort of markup

35
00:02:33,370 --> 00:02:38,010
as you people missing from this and
you know rubber's the is a guy i

36
00:02:38,010 --> 00:02:42,230
work with maintaining project look always
been helping with this time you must be a

37
00:02:42,230 --> 00:02:45,600
he's on the graphics team at that in D C

38
00:02:46,240 --> 00:02:50,230
i mean a is an intent have been working
with that visit ago i could

39
00:02:50,230 --> 00:02:54,520
chris cummings he's been helping out there
as well actually we cows a visual design

40
00:02:54,520 --> 00:02:57,360
it did this markup and help with
the visuals of this project

41
00:02:58,030 --> 00:03:00,880
the change rate has been helping out as well so

42
00:03:04,700 --> 00:03:05,850
and so

43
00:03:06,530 --> 00:03:10,870
i want to give a bit of background
to why i started this project

44
00:03:11,890 --> 00:03:17,700
and so the focus a good friend
so i mean this the body aim of

45
00:03:17,700 --> 00:03:20,350
this project is the to

46
00:03:21,270 --> 00:03:27,060
to drive innovation in the space of user interface
is we're looking to explore for

47
00:03:27,060 --> 00:03:28,810
the use of the G P because

48
00:03:30,570 --> 00:03:31,520
so

49
00:03:31,960 --> 00:03:35,830
well actually just about because i i'm just
gonna be a little bit rougher many

50
00:03:35,830 --> 00:03:38,580
"'cause" i haven't run through this but so

51
00:03:40,280 --> 00:03:45,020
during that experience of say five years
of me working and you i technologies i

52
00:03:45,020 --> 00:03:45,710
guess i've

53
00:03:46,110 --> 00:03:47,220
built up this

54
00:03:47,590 --> 00:03:49,210
kind of feeling that

55
00:03:50,510 --> 00:03:55,290
you do we are completely you will not we
were really wasting this gpu hardware

56
00:03:55,290 --> 00:04:00,330
which is in our devices like mobile phones
and a not tablets in a laptops

57
00:04:00,330 --> 00:04:06,770
the state of you i technologies today we
used a gpu for basically shifting tech

58
00:04:06,770 --> 00:04:10,670
should rectangles around and so i've had this
mounting feeling that is gonna be something

59
00:04:10,670 --> 00:04:11,840
that we can do to

60
00:04:12,250 --> 00:04:17,680
expose more creativity to the visual design
braces an expose that gpu out with a

61
00:04:17,680 --> 00:04:21,300
fully utilising the G P S as what
i want to go through a bit

62
00:04:21,300 --> 00:04:21,660
more

63
00:04:22,200 --> 00:04:28,110
okay so and this and that through that experience
of working with visual design is

64
00:04:28,110 --> 00:04:32,990
what can we do to optimize the website
from coming up with an idea to

65
00:04:32,990 --> 00:04:37,240
create an application something just
quickly recap state-of-the-art them

66
00:04:37,850 --> 00:04:38,620
state-of-the-art

67
00:04:39,790 --> 00:04:45,400
toolkits like G T K G T S waiting
list plus the you pass and

68
00:04:45,400 --> 00:04:49,400
even web technologies the that with
familiar with that web okay

69
00:04:51,850 --> 00:04:55,950
all of these are actually extremely similar technically
speaking if you look at how they

70
00:04:55,950 --> 00:04:56,870
work

71
00:04:57,840 --> 00:04:58,640
and it's

72
00:04:59,480 --> 00:05:05,470
they so they basically implement some form of the postscript
or pdf rendering model is

73
00:05:05,470 --> 00:05:09,600
the foundation of the vocabulary by which
all of these technologies work

74
00:05:09,970 --> 00:05:10,860
with and

75
00:05:11,500 --> 00:05:13,000
so that vocabulary

76
00:05:14,230 --> 00:05:16,000
in essence is these

77
00:05:16,310 --> 00:05:21,010
three things it is just you have to
D shapes you can fill them with

78
00:05:21,010 --> 00:05:26,960
images there's two D shapes a basically just always
rectangles i rounded rectangles if you

79
00:05:26,960 --> 00:05:31,290
getting pretty fancy and you know theoretically
you can use basic us and all that

80
00:05:31,290 --> 00:05:32,240
fancy stuff but

81
00:05:32,690 --> 00:05:34,090
who actually doesn't

82
00:05:35,830 --> 00:05:39,800
you fill these two D shapes with images and
you have text that's your vocabulary

83
00:05:40,960 --> 00:05:44,730
i don't these are all built up you
build you why up using the paint

84
00:05:44,730 --> 00:05:48,070
is everything which just means
that store the background and

85
00:05:48,440 --> 00:05:53,380
will basically familiar with this a really
a background press you met grant and then

86
00:05:53,380 --> 00:05:56,820
your labels and foreground on top of that that's the model

87
00:05:57,560 --> 00:05:58,060
and

88
00:05:58,560 --> 00:06:03,910
you have all they we employ some form of seeing
graph to organise the primitives

89
00:06:03,910 --> 00:06:09,020
the which it's the components of the you
why so you have a hierarchy with

90
00:06:09,020 --> 00:06:12,090
the window the top and this is what defines

91
00:06:12,850 --> 00:06:16,020
how you implement the paint is that within
the stuff the top of the profits

92
00:06:16,020 --> 00:06:17,160
of is the background

93
00:06:17,890 --> 00:06:24,710
and the leaves a of the foreground just
pretty simple it works to some extent

94
00:06:24,710 --> 00:06:29,600
i mean the cornerstone of that model is
the quality of those static images that

95
00:06:29,600 --> 00:06:31,500
you get from your visual design that's

96
00:06:32,700 --> 00:06:34,740
so these technologies

97
00:06:35,110 --> 00:06:39,400
pretty much all i mean to engine is
so that's part of the problem now

98
00:06:39,400 --> 00:06:44,070
the come as an imperative A P I C python and such things

99
00:06:44,520 --> 00:06:47,280
they have a markup language so

100
00:06:47,610 --> 00:06:50,660
will familiar with H T M L with but
there are things that you amount

101
00:06:50,660 --> 00:06:51,400
as well

102
00:06:52,390 --> 00:06:53,220
and it's

103
00:06:54,110 --> 00:06:59,150
yes they all have this of sort of this
contract and this promise that they

104
00:06:59,150 --> 00:07:03,950
will as you develop these technologies you
will to find a an interface for engineers

105
00:07:03,950 --> 00:07:06,650
to work to and you must keep that's tables so

106
00:07:07,950 --> 00:07:12,610
you know there's a button involved in maintaining
a stable interface say that all of

107
00:07:12,610 --> 00:07:17,490
your existing applications don't break as you
of all that technology so is pretty darn

108
00:07:17,490 --> 00:07:21,380
hard to think ahead of time what interface
am i gonna be have to stick

109
00:07:21,380 --> 00:07:25,320
to for the for the rest of time that
i'm not gonna pay myself into

110
00:07:25,320 --> 00:07:29,730
a corner as to how we can improve the flexibility of this

111
00:07:29,840 --> 00:07:34,360
this technology visually speaking and
enable more creativity for designers

112
00:07:34,610 --> 00:07:36,700
it's that's difficult

113
00:07:38,410 --> 00:07:43,810
so i sort of said this year this overwhelming
failure of through this experience that

114
00:07:43,810 --> 00:07:45,680
we could do so much more with the

115
00:07:46,880 --> 00:07:48,670
more creative use of the gpu

116
00:07:49,970 --> 00:07:50,710
so

117
00:07:51,790 --> 00:07:57,670
this is spelling out of the be a the problem
so we've got this the

118
00:07:57,670 --> 00:08:01,230
first one is this limited vocabulary
is the P D F postscript

119
00:08:01,530 --> 00:08:05,260
rendering model it is like twenty five years so it's

120
00:08:07,020 --> 00:08:08,250
and hasn't changed

121
00:08:09,370 --> 00:08:13,920
so we've got the middleman toolkits
this is the this sort of

122
00:08:14,950 --> 00:08:19,650
liar where it's a means to an end these
toolkit so just there for an

123
00:08:19,650 --> 00:08:24,970
engineer to recreate the vision of the designer
and this is sort of a language

124
00:08:24,970 --> 00:08:30,990
barrier between that vision and the technology
the designers tend to have very little insight

125
00:08:30,990 --> 00:08:35,710
into the working of these technologies so the really
obvious middleman and maybe we can

126
00:08:35,710 --> 00:08:38,780
think about ways of not having quite the same

127
00:08:39,420 --> 00:08:42,200
approach and avoid that middleman sort of

128
00:08:42,620 --> 00:08:44,930
translation that we that we deal with today

129
00:08:46,350 --> 00:08:51,070
and when we think about it from the designer's
perspective as well

130
00:08:51,910 --> 00:08:56,200
they're using tools like photoshop well in escape

131
00:08:57,250 --> 00:08:59,600
and things like aftereffects

132
00:09:00,480 --> 00:09:04,690
these are the intended for creating static images

133
00:09:05,060 --> 00:09:08,600
and they have all kinds of fancy effects
available to them by the end of

134
00:09:08,600 --> 00:09:12,280
that you get a beta emission and we
slice up and the rectangles and or

135
00:09:12,280 --> 00:09:17,000
you are with that all the made for offline video

136
00:09:17,340 --> 00:09:21,750
pricing like aftereffects and that uses things
like ray tracing to come up with this

137
00:09:21,750 --> 00:09:25,850
affects you know there's no way those kinds
of effects are gonna run in real

138
00:09:25,850 --> 00:09:29,310
time on a firing anytime see

139
00:09:30,730 --> 00:09:32,660
and so

140
00:09:33,060 --> 00:09:37,930
well these designers are actually trying to
do is create interfaces that can run on

141
00:09:37,930 --> 00:09:41,720
a results constrained device and be responsive to in the

142
00:09:42,370 --> 00:09:49,550
and just you well within a power
sort of constrained and it's

143
00:09:52,410 --> 00:09:57,340
so they really don't at the moment have tools
are actually geared towards that specific

144
00:09:57,340 --> 00:09:59,850
problem so maybe we can think about

145
00:10:01,600 --> 00:10:03,480
inventing new tools that right

146
00:10:03,890 --> 00:10:04,710
improve that part

147
00:10:05,980 --> 00:10:06,760
so

148
00:10:07,180 --> 00:10:09,910
that is just the actual what fly

149
00:10:10,740 --> 00:10:16,230
the very plastic sort of outline of how
design goes of them i mean is

150
00:10:16,230 --> 00:10:18,570
you have the special design a

151
00:10:19,070 --> 00:10:25,520
creates sort of sketches out is vision in something
like photoshop to indicate

152
00:10:26,100 --> 00:10:31,070
and they had over the wall if you
like to the engineer who has to

153
00:10:31,070 --> 00:10:37,850
reinterpret that vision and translate that
into and i pi a sort of fashion so

154
00:10:39,080 --> 00:10:44,180
that the this station totally disconnected from
the sort of visual creative side of things

155
00:10:44,180 --> 00:10:48,680
that are opening up your reference manuals and implementing
this and that implement is typically

156
00:10:48,680 --> 00:10:51,730
on that desktop machine a laptop or so
even if they are trying to create

157
00:10:51,730 --> 00:10:55,030
something for fun you can initially
priced at the stuff on your laptop

158
00:10:55,560 --> 00:11:01,470
and once you kind of got it working then
you're gonna started so that's integrate

159
00:11:01,470 --> 00:11:04,930
this with appeal system to be able to cross
compiler whatever it takes to get

160
00:11:04,930 --> 00:11:08,850
it on T of fighting and then start playing
around with that will how does

161
00:11:08,850 --> 00:11:10,860
this before madison's response

162
00:11:11,210 --> 00:11:11,830
and

163
00:11:12,960 --> 00:11:16,940
at that point that way you're actually
starting to test on the device

164
00:11:17,380 --> 00:11:23,070
is a pretty high chance that you're gonna
realise that this like some problem like

165
00:11:23,070 --> 00:11:27,560
it doesn't the design doesn't fit the form
factor like the designer which nist back

166
00:11:27,560 --> 00:11:32,720
expected it to it doesn't respond as
of as of quickly is it needs to

167
00:11:32,720 --> 00:11:37,850
this like so many possibilities that could
just not be quite right and you're gonna

168
00:11:37,850 --> 00:11:41,870
have to go all the way back to square
one where the designer has to

169
00:11:41,870 --> 00:11:46,280
rethink the idea in the interaction model
to be able to work with the technology

170
00:11:46,280 --> 00:11:47,150
that they have

171
00:11:47,630 --> 00:11:52,080
because the alternative is that you go back to engineering
transfixed the technology but that's

172
00:11:52,080 --> 00:11:55,940
the and you know an unknown quantity
as to whether or not you're gonna be

173
00:11:55,940 --> 00:12:00,100
have to fix a technology in time if
you got the time so your options

174
00:12:00,100 --> 00:12:03,560
are pretty slim about point to have to redesign things

175
00:12:05,700 --> 00:12:06,290
and

176
00:12:06,670 --> 00:12:13,010
another aspect of this is the ability
to objectively measure certain

177
00:12:14,360 --> 00:12:20,390
quantities of quality a that there
are important for user interfaces

178
00:12:20,900 --> 00:12:25,340
you a consumer expects that they're fine it's
gonna respond in a timely manner when

179
00:12:25,340 --> 00:12:30,940
they when they touch it lays we've around
the you why their expected not to

180
00:12:30,940 --> 00:12:35,900
redo that battery but i expect a certain
level of visual quality and right now

181
00:12:35,900 --> 00:12:40,570
we don't have the integration in a tooling and the

182
00:12:41,190 --> 00:12:44,690
the processes by which to really make sure that there is

183
00:12:45,260 --> 00:12:50,770
that we're on top of those quantities right through
the whole design development process those

184
00:12:50,770 --> 00:12:54,400
tend to just be a and often will not
so much an article but they're

185
00:12:54,400 --> 00:12:55,650
the end of the line

186
00:12:56,970 --> 00:12:57,960
in the pipe line of

187
00:12:58,670 --> 00:13:00,210
how we develop these things

188
00:13:02,100 --> 00:13:02,630
so

189
00:13:03,330 --> 00:13:07,720
i guess i kind of into the but some
of the solutions to these as

190
00:13:07,720 --> 00:13:09,040
i was going through the problems but

191
00:13:11,170 --> 00:13:12,170
obviously the

192
00:13:12,540 --> 00:13:15,290
one of the main things that we're interested in here is

193
00:13:16,200 --> 00:13:21,830
throwing away that limited price good model
and saying if we can explore way more

194
00:13:21,830 --> 00:13:24,260
features of the gpu to

195
00:13:25,220 --> 00:13:28,900
there's a lot of flexibility in a gpu
what can we are not there and

196
00:13:28,900 --> 00:13:32,740
give to the visual design of so allow
them to just be more creative

197
00:13:34,360 --> 00:13:40,000
the model of the price good model is actually
really difficult to implement efficiently on

198
00:13:40,000 --> 00:13:43,730
a gpu just given the way the gpus
is kind of difficult to avoid the

199
00:13:43,730 --> 00:13:47,450
over draw in the price good model because you
going from background or foreground and

200
00:13:47,450 --> 00:13:52,370
that's the model but you build up to see
your it's hard to avoid colouring

201
00:13:52,370 --> 00:13:59,270
in all of those redundant fragments and pixels
behind the stuff environment of it that's

202
00:13:59,270 --> 00:14:00,840
just quite a tricky problem

203
00:14:03,340 --> 00:14:07,510
and so as you can probably guess from the screenshot
of the beginning of this

204
00:14:07,510 --> 00:14:10,130
talk the a big aspects

205
00:14:10,560 --> 00:14:15,420
to how i've sort of see as being able
to so many of those problems

206
00:14:15,420 --> 00:14:17,300
is to develop a spec tooling

207
00:14:18,140 --> 00:14:22,120
which is what the rig projects as is looking at doing

208
00:14:22,440 --> 00:14:26,110
so what we're doing is we're creating we were actually

209
00:14:26,670 --> 00:14:30,230
trying to learn from how game developers work here because

210
00:14:30,950 --> 00:14:35,260
game developers face so many of the same
problems that we face as you i

211
00:14:35,260 --> 00:14:38,490
developers except that they have

212
00:14:39,020 --> 00:14:43,420
done a much better job of taking advantage
of gpu hardware than we have they

213
00:14:43,420 --> 00:14:47,740
have to create interface they have to create
something that can run in real time

214
00:14:47,740 --> 00:14:53,310
response that you know interactively with the user
interface with the user and we need

215
00:14:53,310 --> 00:14:55,230
to do the same kinds of things

216
00:14:56,470 --> 00:14:57,140
and

217
00:14:58,100 --> 00:15:01,990
the weighted various guys work is
that they have a rendering engine

218
00:15:02,300 --> 00:15:07,510
and they often build up a lot of this
but tools to help them create

219
00:15:07,510 --> 00:15:10,330
their wells create that they games

220
00:15:11,450 --> 00:15:11,960
and

221
00:15:12,490 --> 00:15:17,510
they have to work as well with design
is an engine is and if you

222
00:15:17,510 --> 00:15:22,980
look at projects like unity three D where
they have really quite so you know

223
00:15:22,980 --> 00:15:25,400
capable tooling to be able to connect

224
00:15:25,730 --> 00:15:27,840
that whole works like between

225
00:15:28,640 --> 00:15:37,200
game design is and the engine is the created
this logic and you game itself

226
00:15:37,820 --> 00:15:41,380
so we're looking to sort of reports their
ideas as much possible "'cause" we can

227
00:15:41,380 --> 00:15:44,920
build on their experience especially they
call of that on a lot of work on

228
00:15:44,920 --> 00:15:50,620
into researching algorithms the less is the really
interesting visual things of the G P

229
00:15:50,620 --> 00:15:50,780
A

230
00:15:51,630 --> 00:15:52,290
so

231
00:15:52,980 --> 00:15:56,670
we want to create technology which is the you
are rendering engine that we can

232
00:15:56,670 --> 00:15:59,940
share between something that's gonna deploy onto a device

233
00:16:00,960 --> 00:16:03,990
the route to run a U I and this and that the tool itself is

234
00:16:03,990 --> 00:16:09,110
gonna be using so the design process is actually
constrained by the capabilities of the

235
00:16:09,110 --> 00:16:10,130
technology

236
00:16:10,910 --> 00:16:14,160
so the visual designer was and then

237
00:16:15,650 --> 00:16:18,770
the beginning and specialised tools
during the visual design process

238
00:16:19,160 --> 00:16:24,190
we want them to also the really connecting
that be issue does development stage with

239
00:16:24,190 --> 00:16:28,110
the hardware that they want to design for so we have

240
00:16:28,670 --> 00:16:33,920
the i what we have in implemented even the ability
to have a network connection

241
00:16:33,920 --> 00:16:37,110
between the design so and the device this

242
00:16:37,630 --> 00:16:41,500
that your you you're targeting so that
while you're working in the design so

243
00:16:42,000 --> 00:16:46,360
it's easy play around with animations of things
that's gonna immediately a date

244
00:16:47,010 --> 00:16:51,210
what's on the device so you can pick it
up and check what's the responsiveness

245
00:16:51,210 --> 00:16:57,060
like what's the quality of this like say that
you're connecting testing right so that

246
00:16:57,060 --> 00:17:03,820
early prototyping stage which there's just no substitute
for testing your ideas on real hardware

247
00:17:03,820 --> 00:17:09,520
so we see that as a pretty compelling
way of improving how works like

248
00:17:09,980 --> 00:17:12,350
and optimising the time it takes to develop

249
00:17:13,610 --> 00:17:14,500
applications

250
00:17:16,050 --> 00:17:16,950
the

251
00:17:17,670 --> 00:17:23,220
the last one is necessarily can it will
be done with within the same so

252
00:17:23,220 --> 00:17:25,350
what we need to develop tools

253
00:17:26,910 --> 00:17:33,280
for measuring save the power usage while you're
running you so you testing your you

254
00:17:33,280 --> 00:17:37,120
why on the device are descended asking
you wanna be able to measure so what's

255
00:17:37,120 --> 00:17:43,570
the power usage what i'm doing certain things
or measuring the latency by which

256
00:17:43,990 --> 00:17:45,190
you when use what

257
00:17:45,790 --> 00:17:50,460
how long does it take for the interface
to stop responding to that so even

258
00:17:50,460 --> 00:17:56,530
we're even thinking of things like will high-speed
be at video cameras and a processing

259
00:17:56,890 --> 00:17:58,340
recordings of that kind of thing

260
00:17:59,260 --> 00:18:01,500
we need to think through that problem as well

261
00:18:02,840 --> 00:18:03,260
so

262
00:18:04,160 --> 00:18:06,470
i guess at this point time to just

263
00:18:07,150 --> 00:18:08,400
maybe but

264
00:18:09,440 --> 00:18:13,070
if it was to just jump in and ask questions
especially now that i'm gonna

265
00:18:13,070 --> 00:18:16,440
basically demo a demo a then

266
00:18:17,070 --> 00:18:19,230
just raise and stuff so

267
00:18:20,980 --> 00:18:21,480
and

268
00:18:22,930 --> 00:18:26,440
there's i wasn't really expecting to be
there and then i guess and i've been

269
00:18:26,440 --> 00:18:28,290
hacking on this the chances that this is

270
00:18:31,950 --> 00:18:37,890
so let's this gonna go through
a bit in order to this area on

271
00:18:38,520 --> 00:18:39,720
on the last year is

272
00:18:40,820 --> 00:18:44,920
well so that we're aiming at work can
asset you can work load here so

273
00:18:44,920 --> 00:18:45,840
we are aiming for

274
00:18:47,180 --> 00:18:51,580
this area is where you import say things
that we created that about does it

275
00:18:51,580 --> 00:18:55,820
could be images made by design is impaired
e-shop we could be models made introduced

276
00:18:55,820 --> 00:18:59,740
your max it could be logic was created
by engine is something that needs to

277
00:18:59,740 --> 00:19:05,170
be integrated could be audio and so these kinds of things

278
00:19:05,880 --> 00:19:11,320
and is this the sort of search area
so we can search the images of

279
00:19:11,320 --> 00:19:14,090
videos or whatever

280
00:19:14,530 --> 00:19:16,220
whatever we need and then

281
00:19:16,970 --> 00:19:23,000
people there is assets into the this centre
area which is where we actually build

282
00:19:23,000 --> 00:19:28,650
up the user interface itself we say we can
we get immediate visual feedback about

283
00:19:28,650 --> 00:19:30,770
the scenes that we're trying to create

284
00:19:32,590 --> 00:19:36,190
on the right hand side here which is
public to the moment but this bottle

285
00:19:36,190 --> 00:19:41,640
would be where we would expect a more tooling
capabilities and it's put there so

286
00:19:41,640 --> 00:19:46,350
you can to the trends in the expand
into the space of the interface to

287
00:19:46,350 --> 00:19:51,920
give more detailed information about tutoring and
when you're not using very spending can sort

288
00:19:51,920 --> 00:19:53,490
of shift out of the way

289
00:19:55,250 --> 00:19:58,010
and then down button here this is where we would so

290
00:19:58,550 --> 00:20:02,890
deal with controlling of the problem
is actually it is the best

291
00:20:03,880 --> 00:20:09,920
just as the actually a where this is some of the properties

292
00:20:10,260 --> 00:20:18,210
for the one of the objects investing a this
idea of entities in components and

293
00:20:18,210 --> 00:20:24,460
entity is like something ins is essentially
just relative to a parent in space and

294
00:20:24,460 --> 00:20:29,600
it has a bunch of components that can be associated
that adding more semantic information

295
00:20:29,600 --> 00:20:33,920
to the object the more components year at the most
semantic meaning that thing has

296
00:20:34,840 --> 00:20:35,320
and

297
00:20:36,660 --> 00:20:43,180
these red buttons here about being able to
control the particular property so if you

298
00:20:43,180 --> 00:20:47,170
click one of those and it brings the ads
it that this area down here

299
00:20:47,170 --> 00:20:51,940
which is cooled what is to control is
the initially when we were first that

300
00:20:51,940 --> 00:20:55,730
this is just but online management but that's
in the process of evolving beyond just

301
00:20:56,200 --> 00:21:00,430
key frame based animation at the moment this
is this example is just built around

302
00:21:00,430 --> 00:21:04,340
key frame animations and it's just a

303
00:21:04,780 --> 00:21:05,650
a toy them or

304
00:21:07,480 --> 00:21:11,680
having in the idea i guess in this
case is a fire an application that

305
00:21:11,680 --> 00:21:18,820
we've got notifications bubbling up and something that's
more recently people problem and it's gonna

306
00:21:18,820 --> 00:21:21,590
ten years excellency can see a bit

307
00:21:23,010 --> 00:21:23,810
visual stuff

308
00:21:24,390 --> 00:21:28,570
so you've got down the field of facts which
shows the something better way look

309
00:21:28,570 --> 00:21:31,420
soft it's as modelling out real well camera works

310
00:21:32,640 --> 00:21:38,210
and we're also playing around with shattered
mapping in this example which is way of

311
00:21:38,210 --> 00:21:40,990
having real time that shot as much

312
00:21:42,640 --> 00:21:45,230
and we've also got real time lighting so

313
00:21:50,020 --> 00:21:54,490
and you have a standard a lot of the lights
based on and if you

314
00:22:00,040 --> 00:22:00,760
which is a

315
00:22:01,030 --> 00:22:01,670
so the

316
00:22:02,040 --> 00:22:02,770
is a light source

317
00:22:06,180 --> 00:22:08,290
well see we're ripping off at the moment it's

318
00:22:08,530 --> 00:22:14,070
very traditional with actually seeing daniel
engines this is largely a as a practical

319
00:22:15,030 --> 00:22:16,230
the this

320
00:22:16,710 --> 00:22:18,100
the practicality because

321
00:22:18,540 --> 00:22:21,110
we have to bring up a whole so it's

322
00:22:22,670 --> 00:22:23,390
there's

323
00:22:23,850 --> 00:22:28,080
we didn't have the time to do the research
and you visual algorithms this one's

324
00:22:28,080 --> 00:22:30,190
a well understood and they work well together

325
00:22:30,980 --> 00:22:34,260
but we'd be looking to do research on that's the

326
00:22:35,480 --> 00:22:41,810
if you a stylised ratio that would be which
is not something you'd necessarily expect

327
00:22:41,810 --> 00:22:44,970
and again but would make more sense in a you why

328
00:22:46,170 --> 00:22:49,620
but even these ones i think that there is scope being

329
00:22:50,830 --> 00:22:54,190
so for having a design and it's
have to use that a so say to

330
00:22:54,190 --> 00:22:58,830
know go overboard because this does
give you a lot of power to

331
00:23:00,310 --> 00:23:00,820
you know

332
00:23:01,300 --> 00:23:06,190
create a you why that would be and
in massive three D virtual kind of

333
00:23:06,190 --> 00:23:11,850
the you could easily go for the problem
is a three D environment that you're

334
00:23:11,850 --> 00:23:14,310
modelling within and but

335
00:23:14,780 --> 00:23:17,630
you don't have to go overboard

336
00:23:18,090 --> 00:23:23,550
so let me just the same time show some of the effects that

337
00:23:25,830 --> 00:23:26,160
that

338
00:23:29,240 --> 00:23:33,300
this one this one doesn't have i have got
assets that really geared towards this

339
00:23:33,300 --> 00:23:34,090
but it's a

340
00:23:36,330 --> 00:23:39,570
a technique that as well uses the G P a bit more than where

341
00:23:40,630 --> 00:23:42,570
doing them i wanted to bump mapping

342
00:23:43,100 --> 00:23:43,810
but it's

343
00:23:44,720 --> 00:23:49,240
your meeting so that that's twenty ten should
have that image but that represents a

344
00:23:49,240 --> 00:23:54,100
modulation in the shape of the a surface
so it makes so it represents a

345
00:23:54,100 --> 00:23:56,270
high essentially and

346
00:23:56,900 --> 00:24:01,760
and you can really see the when i click
that the service that it's the

347
00:24:01,760 --> 00:24:07,350
it changed visually but what's kind of interesting
is when you select the light

348
00:24:08,130 --> 00:24:10,930
and you change the direction of the light goes out

349
00:24:15,680 --> 00:24:16,550
didn't last too

350
00:24:25,040 --> 00:24:31,070
so that's just to stop i found nothing
special about that and the bum not

351
00:24:31,760 --> 00:24:35,930
the case with this was just generated by running
it through a program that uses

352
00:24:35,930 --> 00:24:41,730
essentially so profile to that says there where
there's contrast in the image that they're

353
00:24:41,730 --> 00:24:43,840
edges best it automatically generates

354
00:24:44,300 --> 00:24:47,470
so idea the edges you're moving up there

355
00:24:48,990 --> 00:24:53,080
so if you take the last of the questions
again you see that this like

356
00:24:53,080 --> 00:24:57,190
a detail in this every stick gets changed
the changes we make a lot of

357
00:24:57,190 --> 00:24:59,440
this that this is not some is craft it's

358
00:24:59,850 --> 00:25:03,370
what it's about this but i think with
a bit of have a visual design

359
00:25:03,370 --> 00:25:09,040
and knowing what they wanted to G fan with
us dedicated assets then this room

360
00:25:09,040 --> 00:25:13,600
to make something just bit more dynamic an interesting
that light source might be doesn't

361
00:25:13,600 --> 00:25:17,540
have to be moving know every time you
move your finger around it could look

362
00:25:17,540 --> 00:25:20,840
a little bit over the top but maybe it moves is

363
00:25:21,160 --> 00:25:24,610
as you sort of time between spaces on your fine

364
00:25:27,180 --> 00:25:31,870
another there's another this one is a fine
example of just using the G P

365
00:25:31,870 --> 00:25:34,510
to style as something the

366
00:25:36,840 --> 00:25:37,820
show is

367
00:25:38,960 --> 00:25:40,750
is the video on this

368
00:25:41,040 --> 00:25:44,310
just to show the videos just to show
really that is something that can be

369
00:25:44,310 --> 00:25:50,090
done in real time and this point is
an is court appointed is in the

370
00:25:50,090 --> 00:25:52,900
fact that and all this thing is

371
00:25:53,660 --> 00:25:57,850
great something on the original images scale
this write up so you can see what's

372
00:25:57,850 --> 00:25:58,310
going on

373
00:25:59,000 --> 00:25:59,640
so as well

374
00:25:59,940 --> 00:26:01,020
snapped and things to be have to

375
00:26:01,830 --> 00:26:03,290
to control

376
00:26:04,810 --> 00:26:05,220
and

377
00:26:08,910 --> 00:26:09,800
we can

378
00:26:10,910 --> 00:26:14,410
stylised something and this point is an effect

379
00:26:15,000 --> 00:26:18,620
i guess used quite a bit in static
images and prices of things

380
00:26:19,460 --> 00:26:24,500
but we can do this dynamically and depending
on the lightness of the pixel is

381
00:26:24,500 --> 00:26:29,160
a it within the image then we're changing
the size of some geometry to

382
00:26:30,470 --> 00:26:34,800
to just create is a like nice looking at back to the

383
00:26:35,280 --> 00:26:40,050
might want to have this in on a background
of some aspect of your hard

384
00:26:40,050 --> 00:26:46,500
merrier of a of a device interface is something
that again have to design either

385
00:26:46,500 --> 00:26:49,190
i get to leave it out to them but i'd like to be up to

386
00:26:49,190 --> 00:26:56,820
provide them tools and freedom and but constraint
as well two things i know to

387
00:26:56,820 --> 00:27:02,090
run efficiently on the G P and it's almost
cheaper to run this video effects

388
00:27:02,090 --> 00:27:06,450
then it would be to actually show you the video
normally just because in this

389
00:27:06,450 --> 00:27:09,330
case okay ish

390
00:27:09,950 --> 00:27:12,420
there will be in this case

391
00:27:13,350 --> 00:27:17,790
a the i only points where we do like
colour space conversion that why U

392
00:27:17,790 --> 00:27:23,810
V to rgb of the double points which
we are showing a secretary doing in

393
00:27:23,810 --> 00:27:29,360
some ways less work than you would do
to sure the emission and that's kind

394
00:27:29,360 --> 00:27:30,290
of the but

395
00:27:31,340 --> 00:27:36,910
so that's kind of the state of the two
of them i expect i actually

396
00:27:38,040 --> 00:27:43,820
they way in which the design so to next
to the slave device actually which

397
00:27:45,140 --> 00:27:45,720
nice

398
00:27:46,680 --> 00:27:49,710
so this represents a device sitting on your
desk which might be if i you

399
00:27:49,710 --> 00:27:50,400
know say

400
00:27:55,310 --> 00:27:59,800
well i it i don't have anything that's
got this like running on a real

401
00:27:59,800 --> 00:28:04,840
fine but this is the that we had an hundred
back and that we created

402
00:28:04,840 --> 00:28:09,550
a while ago and but it's like some updating also

403
00:28:19,870 --> 00:28:22,090
so that there's connecting this

404
00:28:22,780 --> 00:28:24,780
design to that device

405
00:28:25,210 --> 00:28:27,890
celebrate from civilisation

406
00:28:28,890 --> 00:28:33,530
so if i scrub through this animation
then you see we have the effects are

407
00:28:33,530 --> 00:28:37,500
enabled on this one well the not in the editing
area so you can get

408
00:28:37,500 --> 00:28:39,680
a feel for what it's like on a device and in here

409
00:28:40,380 --> 00:28:41,020
but then

410
00:28:42,020 --> 00:28:46,700
here if i gotta say to the end
of the time line and grab this

411
00:28:47,590 --> 00:28:49,250
change the animation at the end

412
00:28:49,710 --> 00:28:55,270
about my device so anyway immediately outdated
and it's see going to in czech what's

413
00:28:55,270 --> 00:29:00,720
the timing of that change the key frame it's
right into you constantly you're happy

414
00:29:00,720 --> 00:29:04,390
with the work that while seeing it for real on the actual

415
00:29:05,390 --> 00:29:09,410
and this done using of all here at the moment
so ago zero come so

416
00:29:09,410 --> 00:29:11,270
that it can just discover the device

417
00:29:12,430 --> 00:29:13,660
this is possible

418
00:29:14,880 --> 00:29:20,320
okay so that's basically will content about
the moment to be have to introduce great

419
00:29:20,320 --> 00:29:24,550
but be happy to take any questions and to

420
00:29:25,050 --> 00:29:26,110
okay thanks to

421
00:29:46,800 --> 00:29:48,820
question to you

422
00:29:50,090 --> 00:29:57,170
the point to do so i want to run right
well actually is the that's

423
00:29:57,170 --> 00:29:58,690
not just i if

424
00:29:59,080 --> 00:30:04,160
save for many with the times fragment pricing
in fact expressing in terms of gpu

425
00:30:04,160 --> 00:30:10,420
something like the future as well so often
video effects i just done as fragment

426
00:30:10,420 --> 00:30:16,050
programs like say you are doing just colour
rising or you have to de saturate

427
00:30:16,050 --> 00:30:20,710
or contrast or brightness is kind of thing
you just running over every single bit

428
00:30:20,710 --> 00:30:27,230
pixel in the image in this case where actually
we have geometry for the cells

429
00:30:27,230 --> 00:30:30,160
if you like in that affect

430
00:30:30,610 --> 00:30:31,190
and

431
00:30:31,800 --> 00:30:37,840
it starts off as basically a tiny unit rectangle
for each cell which texture maps

432
00:30:37,840 --> 00:30:45,590
a circle and when it reads through the videos
data i need something on these

433
00:30:45,590 --> 00:30:50,880
course great points so i really does like
that why you be colour space compression

434
00:30:50,880 --> 00:30:55,150
on a specific points looks at the lightness
of those and then depending on the

435
00:30:55,150 --> 00:31:01,050
like this is essentially scaling out that geometry
so i've rule you're doing way less

436
00:31:01,050 --> 00:31:05,770
fragment processing then you would often differ
a bit effect a and you're moving a

437
00:31:05,770 --> 00:31:13,120
bit to the you know the but there was
really interesting to what i'm what

438
00:31:13,120 --> 00:31:19,310
is you some that's in the tool designers can use

439
00:31:20,130 --> 00:31:22,710
so someone to explore

440
00:31:25,100 --> 00:31:35,760
i was so you wouldn't be able to see yes is so what are the

441
00:31:35,760 --> 00:31:42,910
particular a design decisions made a is the it
doesn't really doesn't really scale to

442
00:31:42,910 --> 00:31:47,760
try to come up with them really modularising
rendering system like at the extreme where

443
00:31:47,760 --> 00:31:51,310
we have class to well i mean it's
changed now but we you know with

444
00:31:51,310 --> 00:31:53,280
to use to be able to have a so that

445
00:31:54,010 --> 00:32:00,980
every single actor could write all kinds of in narrative
card to do alighted roaring

446
00:32:00,980 --> 00:32:06,940
and it's very flexible but if you want
to optimize how use a gpu you

447
00:32:06,940 --> 00:32:12,720
tend to have to do really classy with things
and make various assumptions and it

448
00:32:12,720 --> 00:32:16,360
works a lot better if you just make
that piece of rendering card a lot

449
00:32:16,360 --> 00:32:22,370
more monolithic so enrage it's much more sort
of like a game engine monolithic rendering

450
00:32:22,370 --> 00:32:27,370
engine and if you wanna extend a then that

451
00:32:28,120 --> 00:32:30,770
the then you basically

452
00:32:31,100 --> 00:32:35,910
the engine is to have this specialised experience
to know how to program a gpu

453
00:32:35,910 --> 00:32:41,580
efficiently they should come and should be every
project and at their affects another features

454
00:32:41,580 --> 00:32:46,340
that because the number of people that
have specialising gpu programming

455
00:32:46,810 --> 00:32:51,520
is barry lighter in terms of the number of people
the ones right applications so

456
00:32:51,520 --> 00:32:57,770
we can expect application developers to
be writing G S L and we're you know

457
00:32:57,770 --> 00:33:04,490
sort of shade ascends integrating their rendering
ideas it a into a modular system and

458
00:33:04,490 --> 00:33:09,790
also get the performance we will amount is that

459
00:33:15,000 --> 00:33:18,210
so a couple questions the first is

460
00:33:20,580 --> 00:33:24,810
what do you actually sending to the devices
it just is just display list basically

461
00:33:24,810 --> 00:33:30,910
with animation descriptions and i didn't have
the network to device but well the whole

462
00:33:30,910 --> 00:33:34,920
the rendering engine itself is running on a device
or the description of the scene

463
00:33:34,920 --> 00:33:38,330
which is we have this seen trough of

464
00:33:38,810 --> 00:33:42,100
entities and entities just

465
00:33:42,760 --> 00:33:46,560
there they just have a position in three
D which can be write a sin

466
00:33:46,560 --> 00:33:51,020
transform relative to a parent and potentially
we could be sending multiple would be seeing

467
00:33:51,020 --> 00:33:57,220
grass and each component has each entity
has a bunch of components which say ads

468
00:33:57,220 --> 00:34:03,040
the idea that you have material which
says how should be lit or some sort

469
00:34:03,040 --> 00:34:10,380
of video source image source it could be some
logic associated with that entity that

470
00:34:10,380 --> 00:34:13,860
triggers when you have input all
this what kind of high level

471
00:34:14,250 --> 00:34:19,670
sort of semantic description it's what's gonna
get sent over the wire to the device

472
00:34:19,670 --> 00:34:22,480
and it's gonna like that

473
00:34:24,340 --> 00:34:28,630
second of which in the my second question
you talked about it kind of like

474
00:34:29,590 --> 00:34:35,400
already against are they created a their
scene with reagan so like a game engine

475
00:34:35,400 --> 00:34:40,590
so when it comes time to actually like should
the application of a shipping the

476
00:34:40,590 --> 00:34:44,750
maybe so what you know where they shipping
the all the assets and then this

477
00:34:44,970 --> 00:34:47,010
description it's interpreted

478
00:34:47,380 --> 00:34:51,590
well that's because the way the than the network
writable has to be able to

479
00:34:51,590 --> 00:34:59,550
serialise everything that relates to be the description
of the scene including bss themselves and

480
00:34:59,550 --> 00:35:05,460
we also use this so we using part school
buses which quite widely used way

481
00:35:05,460 --> 00:35:10,460
of civilised later and they give you a nice markup
for describing messages for stabilising

482
00:35:10,460 --> 00:35:16,240
data and we use the same particle we
use the same mechanism for being a

483
00:35:16,240 --> 00:35:20,860
to stabilise over the network as we do
for stabilising to this when we is

484
00:35:20,860 --> 00:35:25,480
at the moment when we see realised that this
we're keeping references to external assets

485
00:35:25,480 --> 00:35:30,460
but if you're gonna make it for distribution
on device then we would also be

486
00:35:30,460 --> 00:35:34,970
see realising bss themselves in the same
way that we do for the network and

487
00:35:34,970 --> 00:35:39,020
you would just have this one top rate file which you just

488
00:35:39,420 --> 00:35:44,030
and put on the device along with the actual read

489
00:35:45,360 --> 00:35:49,120
sort of engine itself built in three
ways the i the bills with all of

490
00:35:49,120 --> 00:35:53,110
the editing capabilities around it or it builds

491
00:35:53,820 --> 00:35:57,940
in as a slave the sort of it as a slave so the one on

492
00:35:57,940 --> 00:36:00,930
a device which has that network transparency or just

493
00:36:01,460 --> 00:36:05,530
for deployment of device it doesn't need to network
transparency doesn't need any day editing

494
00:36:05,530 --> 00:36:11,310
capabilities it's quite got basically no
dependencies exact G L at that point and

495
00:36:13,290 --> 00:36:18,320
huge ship that device might plus your top
rate file which has everything sort of

496
00:36:18,320 --> 00:36:19,450
sailors together

497
00:36:21,490 --> 00:36:25,250
so one final question have you considered a

498
00:36:28,420 --> 00:36:35,240
a web device so i probably but it actually
say this so we we're interested

499
00:36:35,240 --> 00:36:40,660
in supporting a bunch of platforms with this
and that includes web development in fact

500
00:36:40,660 --> 00:36:46,100
so this way we have got the fold
them are working but i'm the i

501
00:36:46,100 --> 00:36:48,210
at least we want to do the proof of concept is

502
00:36:48,950 --> 00:36:52,450
see if it's feasible and i'm kind of optimistic
that is because we have the

503
00:36:52,450 --> 00:36:57,260
rendering side working with web G L
and so you know this depends on G

504
00:36:57,260 --> 00:37:00,630
L to do to have access to the G P we trying to projects the

505
00:37:00,630 --> 00:37:01,970
gpu the only

506
00:37:02,560 --> 00:37:05,900
weighted we can do that in the context
of the web is web geo and

507
00:37:05,900 --> 00:37:07,660
it looks like that's gonna basically be

508
00:37:08,230 --> 00:37:12,520
across all major browsers that is soon including i and so

509
00:37:13,120 --> 00:37:13,760
that's

510
00:37:14,540 --> 00:37:16,480
that's where we're looking to go

511
00:37:19,300 --> 00:37:27,890
so you mentioned that the friendly model
we should try to not a bill with

512
00:37:27,890 --> 00:37:33,810
like you know the we that anymore so you
have a specific a specific examples

513
00:37:33,810 --> 00:37:35,730
of how we

514
00:37:38,360 --> 00:37:44,260
so apply principles that re well probably
uses to get rid of the P D

515
00:37:44,260 --> 00:37:50,170
F really model like well run vision even
this initial example but the way that

516
00:37:50,170 --> 00:37:55,450
you build this particular scene out it's got
intermediate rent is where you have to

517
00:37:55,450 --> 00:38:01,890
first determine that if this geometry up
before you're able to come up with the

518
00:38:01,890 --> 00:38:09,390
blurring this based on that distance and the there
are multiple stages involved in coming

519
00:38:09,390 --> 00:38:12,970
up with that final is so you have to do it is a it is

520
00:38:12,970 --> 00:38:17,040
a step where you look from the perspective
of the like for instance just say

521
00:38:17,040 --> 00:38:21,700
well from the lights perspective what geometry
can i see said i can determine what

522
00:38:21,700 --> 00:38:29,120
geometries in shadow and you know this there's
a whole bunch more involved in that

523
00:38:29,120 --> 00:38:31,950
model of rendering which is completely different

524
00:38:33,080 --> 00:38:36,730
the postscript model of you know you just
draw your background you draw other stuff

525
00:38:36,730 --> 00:38:40,540
on top of it in the middle and you
draw your labels and stuff the

526
00:38:40,540 --> 00:38:44,940
is just a that's a completely different
model you couldn't achieve

527
00:38:45,420 --> 00:38:48,460
this kind of thing with the postscript model in real time

528
00:38:49,520 --> 00:38:53,710
but is the other things like i'd be interested
it's at least exploring some of

529
00:38:53,710 --> 00:38:59,760
the stylised to painterly rendering or so
where do we can make something look a

530
00:38:59,760 --> 00:39:04,930
bit like it was painted with oil paints
or the like it was sketch just

531
00:39:04,930 --> 00:39:06,400
something aesthetically

532
00:39:08,590 --> 00:39:10,970
you know interesting there is a

533
00:39:11,540 --> 00:39:18,010
that would that would take your completely different
approaches to rendering as well then even

534
00:39:18,010 --> 00:39:19,270
what i just described there

535
00:39:20,070 --> 00:39:23,400
and so these are the really quite far removed from that

536
00:39:24,360 --> 00:39:30,040
painter's algorithm hands and the vocabulary
of two D shapes text and images

537
00:39:32,060 --> 00:39:32,590
is that

538
00:39:33,190 --> 00:39:33,980
that makes sense

539
00:39:35,060 --> 00:39:39,590
i'm thinking of something like the broadsword
browser for example yes you know very complex

540
00:39:39,590 --> 00:39:45,020
you have to support a lot of different techniques
for throwing a so probably we

541
00:39:45,020 --> 00:39:49,270
could not completely get rid of all
P D F and the remote but maybe

542
00:39:49,270 --> 00:39:53,410
some of the principles that you
a scribe know could be applied

543
00:39:54,110 --> 00:40:00,210
so probably you have some specific you know
experience with their potentially be way so

544
00:40:00,210 --> 00:40:01,200
you could

545
00:40:01,970 --> 00:40:09,460
other ad rendering a new a rendering model capabilities
within the browser but it works

546
00:40:11,990 --> 00:40:13,490
i to be sort of

547
00:40:14,720 --> 00:40:18,570
sandbox to some region and then you
get this new model to use in a

548
00:40:18,570 --> 00:40:25,060
certain area it would be challenging to fit the postscript
model within a different model

549
00:40:25,060 --> 00:40:25,340
in that

550
00:40:26,630 --> 00:40:30,440
this in these in a lot of these cases
you're using that to determine a

551
00:40:30,440 --> 00:40:35,460
something is behind something else so you have to other

552
00:40:36,750 --> 00:40:42,240
trying to fight the idea of the postscript
tiring in terms of shifting things that

553
00:40:42,240 --> 00:40:45,500
you might be able to sort of rhetoric
that's on this about stuff into the

554
00:40:45,500 --> 00:40:45,850
and

555
00:40:46,560 --> 00:40:48,160
a some browsers which has

556
00:40:49,380 --> 00:40:49,940
but

557
00:40:50,750 --> 00:40:54,680
maybe we can chat afterwards of that's
different is if you interested

558
00:41:01,020 --> 00:41:02,110
go thanks

559
00:41:03,120 --> 00:41:03,250
so
