In 1962, Buckminster Fuller
0
19330
2000
Buckminster Fuller于1952年
00:21
presented the particularly audacious proposal for the Geoscope.
1
21330
4000
提出一个有关潜望镜的大胆提议。
00:25
It was a 200-foot diameter geodesic sphere
2
25330
3000
一个直径有200尺的测地球体
00:28
to be suspended over the East River in New York City, in full view of the United Nations.
3
28330
5000
并将其悬挂在纽约市东河,同时可以看到联合国大楼全景。
00:33
It was a big idea, for sure, and it was one that he felt could truly inform
4
33330
6000
的确很大胆,他认为这个设计可以
00:39
and deeply affect the decision making of this body
5
39330
4000
通过球体的动态数据与、影像
00:43
through animations of global data, trends
6
43330
4000
以及全球问题
00:47
and other information regarding the globe, on this sphere.
7
47330
4000
以提醒作为持有决定权的联合国
00:51
And today, 45 years later,
8
51330
3000
45年后的今天,
00:54
we clearly have no less need for this kind of clarity and perspective,
9
54330
3000
我们仍需要这种透彻的见解,
00:57
but what we do have is improved technology.
10
57330
3000
同时我们还具有飞速进步的科技。
01:00
Today we don't need one million light bulbs to create a spherical display.
11
60330
3000
今天我们已不需上万个灯泡来照亮球体。
01:03
We can use LEDs.
12
63330
2000
我们已经有发光二极管了。
01:05
LEDs are smaller, they're cheaper, they're longer lasting, they're more efficient.
13
65330
5000
发光二极管小而便宜,还很耐用,以及节能。
01:10
Most importantly for this, they're faster.
14
70330
2000
最重要的是,发光二极管很快。
01:12
And this speed, combined with today's high-performance micro-controllers,
15
72330
4000
以它们的速度,加上今天的高性能微星控制器
01:16
allows us to actually simulate, in this piece,
16
76330
3000
让我们能够用64块二极发光管模拟
01:19
over 17,000 LEDs -- using just 64.
17
79330
4000
17000块二极发光管。
01:24
And the way this happens is through the phenomenon of persistence of vision.
18
84330
4000
这是利用了视觉停留现象。
01:28
But as this ring rotates at about 1,700 rpm -- that's 28 times per second.
19
88330
4000
但在球体每分旋转高达1700圈,也就是每秒28圈时。
01:33
The equator's speed is actually about 60 miles per hour.
20
93330
3000
赤道时速也就60英里每小时。
01:36
There are four on-board micro-controllers
21
96330
2000
球体有4个内置微星控制器
01:38
that, each time this ring rotates
22
98330
3000
当球体每旋转
01:41
it, as it passes the rear of the display,
23
101330
2000
至屏幕的后方时
01:43
it picks up a position signal.
24
103330
2000
它会接收到一个位置信号
01:45
And from that, the on-board micro-controllers
25
105330
2000
从而引导微星控制器
01:47
can extrapolate the position of the ring at all points around the revolution
26
107330
5000
推断球体在整个旋转中的位置
01:52
and display arbitrary bitmap images and animations.
27
112330
3000
再显示推断的位图图像及影像。
01:55
But this is really just the beginning.
28
115330
3000
这只是开始
01:58
In addition to higher resolution versions of this display,
29
118330
3000
除了高分辨率显示以外,
02:01
my father and I are working on a new patent-pending design
30
121330
3000
我父亲和我正在争取一项新设计注册专利,
02:04
for a fully volumetric display using the same phenomenon.
31
124330
3000
一个运用相同原理来测定体积的技术。
02:07
It achieves this by rotating LEDs about two axes.
32
127330
3000
这是通过在两个轨道旋转二极发光管来实现的。
02:10
So as you can see here, this is a, eleven-inch diameter circuit board.
33
130330
3000
正如你所看到,这是一个直径11寸的线路板。
02:13
These blocks represent LEDs.
34
133330
2000
这些方块代表二极发光管。
02:15
And so you could see that as this disc rotates about this axis,
35
135330
4000
这些圆圈围绕这个中心旋转,
02:19
it will create a disc of light that we can control.
36
139330
3000
它形成的光环是可控的。
02:22
That's nothing new: that's a propeller clock;
37
142330
2000
这没什么新鲜的,这就是螺旋桨时钟。
02:24
that's the rims that you can buy for your car.
38
144330
3000
你的车可能会用到这个远程信息管理系统。
02:27
But what is new is that, when we rotate this disc about this axis,
39
147330
5000
新鲜的是,当圆圈围绕中心旋转时
02:32
this disc of light actually becomes a sphere of light.
40
152330
3000
这样光圈实际上可变成光球。
02:35
And so we can control that with micro-controllers
41
155330
2000
我们可以用微星控制器操控
02:37
and create a fully volumetric, three-dimensional display with just 256 LEDs.
42
157330
6000
仅用256块二极发光管就组成测量体积的三维显示。
02:43
Now this piece is currently in process --
43
163330
2000
这个现在还在研制中--
02:45
due out in May -- but what we've done is we've put together a small demo,
44
165330
5000
5月份就会问世,为此我们进行了一个小型展示会,
02:50
just to show the geometric translation of points into a sphere.
45
170330
4000
以展示几何是如何融入到球体中。
02:54
I've got a little video to show you,
46
174330
2000
这儿还有个视频,
02:56
but keep in mind that this is with no electronic control,
47
176330
4000
不过这个没有电子控制,
03:00
and this is also with only four LEDs.
48
180330
2000
而且只有4块二极发光管。
03:02
This is actually only about 1.5 percent of what the final display will be in May.
49
182330
3000
这只是我们5月展示的1.5%。
03:05
So, take a look.
50
185330
2000
瞧瞧吧。
03:09
And here you can see it's rotating about the vertical axis only, creating circles.
51
189330
4000
这个现在只是围绕垂直轴旋转,形成环形。
03:17
And then, as the other axis kicks in,
52
197330
2000
再加入其他轴线,
03:19
those actually blur into a volume.
53
199330
2000
这些都融入一个体积内。
03:21
And the shutter speed of the camera
54
201330
2000
和高速摄像机
03:23
actually makes it slightly less effective in this case.
55
203330
3000
不过不是很高效。
03:26
But this piece is due out in May.
56
206330
2000
这个5月份面世。
03:28
It'll be on display at the Interactive Telecommunications Spring Show
57
208330
3000
会在春季互动电信展会上展出,
03:31
in Greenwich Village in New York City -- that's open to the public,
58
211330
2000
是在纽约格林威治村举行。
03:33
definitely invite you all to come and attend -- it's a fantastic show.
59
213330
4000
我会邀请大家的--这个展览很棒。
03:37
There are hundreds of student innovators with fantastic projects.
60
217330
4000
会展上有上百个学生发明家,他们有绝妙的设计。
03:41
This piece, actually, will be on display
61
221330
2000
这个会被展出
03:43
down in the Sierra Simulcast Lounge
62
223330
2000
于Sierra Simulcast大厅。
03:45
in the breaks between now and the end of the show.
63
225330
2000
直到展览结束。
03:47
So I'd love to talk to you all, and invite you
64
227330
2000
很荣幸向大家介绍,我也很乐意邀请大家
03:49
to come down and take a closer look.
65
229330
2000
来亲眼看看。
03:51
It's an honor to be here. Thanks very much.
66
231330
2000
今天能登台很荣幸,非常感谢。
03:53
(Applause)
67
233330
1000
(鼓掌)
