由細胞分裂中取得靈感，Michael Hansmeyer 寫成能設計出令人嘆為觀止，具有數百萬面向的形體的運算程式。沒人能以手繪畫出這些形體，但它們卻是可以建造的。它們同時也進化我們思考建築形體的方式。

As an architect, I often ask myself,
0
470
2449
身為一名建築師，我經常問我自己
00:18
what is the origin of the forms that we design?
1
2919
2840
什麼是我們設計的源頭
00:21
What kind of forms could we design
2
5759
2905
如果完全不參考其它作品
00:24
if we wouldn't work with references anymore?
3
8664
2823
我們會設計出什麼樣式呢?
00:27
If we had no bias, if we had no preconceptions,
4
11487
3385
如果我們沒有偏好，沒有先入為主的印象
00:30
what kind of forms could we design
5
14872
2207
我們會設計出什麼的形體？
00:32
if we could free ourselves from
6
17079
1600
假如 我們將自已從
00:34
our experience?
7
18679
2136
積累的經驗中解錮出來
00:36
If we could free ourselves from our education?
8
20815
4734
或跳出教育的框架呢?
00:41
What would these unseen forms look like?
9
25549
3027
這前所未見的形式 看起來會像是甚麼
00:44
Would they surprise us? Would they intrigue us?
10
28576
3711
會帶給我們驚喜嗎? 會讓我們感興趣嗎？
00:48
Would they delight us?
11
32287
2415
它會讓我們感到歡欣嗎
00:50
If so, then how can we go about creating something that is truly new?
12
34702
3921
若是如此， 我們該如何著手開創全新的東西呢？
00:54
I propose we look to nature.
13
38623
2392
我建議師法大自然
00:56
Nature has been called the greatest architect of forms.
14
41015
4264
大自然是最偉大的形態建築師
01:01
And I'm not saying that we should copy nature,
15
45279
3588
在這裡，我並不建議僅僅複製大自然
01:04
I'm not saying we should mimic biology,
16
48867
2380
我不是說我們應該抄襲自然生物
01:07
instead I propose that we can borrow nature's processes.
17
51247
3448
相反地，我希望我們能借鑒大自然造物的過程。
01:10
We can abstract them and to create something that is new.
18
54695
4454
從中擷取，並創造出全新的形態
01:15
Nature's main process of creation, morphogenesis,
19
59149
3878
大自然主要的創造過程，最初的形體生成
01:18
is the splitting of one cell into two cells.
20
63027
3829
是將細胞一分為二。
01:22
And these cells can either be identical,
21
66856
2057
而這些細胞不是完全相同，
01:24
or they can be distinct from each other
22
68913
2175
就是透過不對稱細胞分裂
01:26
through asymmetric cell division.
23
71088
2064
形成完全不同的形態
01:29
If we abstract this process, and simplify it as much as possible,
24
73152
3799
假使我們能擷取這個過程並盡可能簡化它，
01:32
then we could start with a single sheet of paper,
25
76951
2233
那麼，我們便能簡單地從一張紙和
01:35
one surface, and we could make a fold
26
79184
2496
一個面向開始，利用摺疊
01:37
and divide the surface into two surfaces.
27
81680
2936
將一個面分為兩個面向。
01:40
We're free to choose where we make the fold.
28
84616
2263
我們可以自由選擇要如何對摺
01:42
And by doing so, we can differentiate the surfaces.
29
86879
4910
並藉此區別各面向。
01:47
Through this very simple process,
30
91789
1894
透過這個簡單的步驟，
01:49
we can create an astounding variety of forms.
31
93683
3612
我們能創造出令人驚艷的各種形態。
01:53
Now, we can take this form and use the same process
32
97295
2725
現在，我們可以利用這個形態和相同步驟
01:55
to generate three-dimensional structures,
33
100020
1992
來創造出三度空間立體的架構
01:57
but rather than folding things by hand,
34
102012
2408
但並不是徒手摺疊
02:00
we'll bring the structure into the computer,
35
104420
2585
而是將這個結構輸入到電腦
02:02
and code it as an algorithm.
36
107005
2975
並把它編碼成一個演算法。
02:05
And in doing so, we can suddenly fold anything.
37
109980
3008
如此一來，我們就能瞬間摺疊任何東西。
02:08
We can fold a million times faster,
38
112988
2159
我們摺疊的速度可以快上百萬倍，
02:11
we can fold in hundreds and hundreds of variations.
39
115147
3161
我們可以摺疊出成千上萬的變化，
02:14
And as we're seeking to make something three-dimensional,
40
118308
2480
而當我們企圖創造一些三度空間的立體物件時，
02:16
we start not with a single surface, but with a volume.
41
120788
3216
就不再是從單一平面開始，而是從體積開始，
02:19
A simple volume, the cube.
42
124004
1353
以簡單的立方體為例。
02:21
If we take its surfaces and fold them
43
125357
1720
假使我們將其平面
02:22
again and again and again and again,
44
127077
2056
不斷、不斷、不斷、不斷地
02:25
then after 16 iterations, 16 steps,
45
129133
2863
經過16次的反覆摺疊後，
02:27
we end up with 400,000 surfaces and a shape that looks,
46
131996
3849
最後會得到400,000個面向，以及一個看起來
02:31
for instance, like this.
47
135845
2535
譬如說，像這樣的形態。
02:34
And if we change where we make the folds,
48
138380
2712
假設我們改變摺疊處，
02:36
if we change the folding ratio,
49
141092
1641
或是摺疊的比例，
02:38
then this cube turns into this one.
50
142733
3423
那這個立方體就會變成這樣。
02:42
We can change the folding ratio again to produce this shape,
51
146156
4139
我們再一次改變摺疊比例可以得到這個、
02:46
or this shape.
52
150295
1827
或是這個形狀。
02:48
So we exert control over the form
53
152122
1623
因此，我們便能藉由針對特定的摺疊位置
02:49
by specifying the position of where we're making the fold,
54
153745
3504
施行對這個形體的控制。
02:53
but essentially you're looking at a folded cube.
55
157249
4706
但本質上來說，你看到的還是一個摺疊過的立方體。
02:57
And we can play with this.
56
161955
1064
我們可以這樣做，
02:58
We can apply different folding ratios to different parts
57
163019
2616
我們可以在立方體的不同部位運用不同摺疊比例，
03:01
of the form to create local conditions.
58
165635
2745
來創造出局部變化。
03:04
We can begin to sculpt the form.
59
168380
1943
我們可以開始雕塑這個形體。
03:06
And because we're doing the folding on the computer,
60
170323
2888
由於我們是在電腦上進行摺疊，
03:09
we are completely free of any physical constraints.
61
173211
3696
所以完全沒有任何實體上的限制。
03:12
So that means that surfaces can intersect themselves,
62
176907
2951
這意味著，各面向能夠自行交叉貫穿，
03:15
they can become impossibly small.
63
179858
1489
變成近乎不可能的小。
03:17
We can make folds that we otherwise could not make.
64
181347
3601
我們能夠做到過去無法達成的摺疊方式。
03:20
Surfaces can become porous.
65
184948
1878
平面變成能穿透的。
03:22
They can stretch. They can tear.
66
186826
2729
它們能夠伸展、能夠被撕裂。
03:25
And all of this expounds the scope of forms that we can produce.
67
189555
4635
而這一切說明了我們所能創造的形態範圍。
03:30
But in each case, I didn't design the form.
68
194190
2750
但在每個作品中，我並不設計形態。
03:32
I designed the process that generated the form.
69
196940
4601
我設計的是一個產生型態的過程。
03:37
In general, if we make a small change to the folding ratio,
70
201541
4488
一般而言，假設我們把摺疊比例作一個小小的改變，
03:41
which is what you're seeing here,
71
206029
1595
就像你在這裡看到的，
03:43
then the form changes correspondingly.
72
207624
3773
整個形態也會相對應地產生改變。
03:47
But that's only half of the story --
73
211397
2256
但這才說到一半而已--
03:49
99.9 percent of the folding ratios produce not this,
74
213653
4323
百分之九十九點九的摺疊比例所產生的並非如此，
03:53
but this, the geometric equivalent of noise.
75
217976
4896
而是像這樣，等同幾何學中的噪音干擾。
03:58
The forms that I showed before were made actually
76
222872
2120
我之前所展示的形態，事實上
04:00
through very long trial and error.
77
224992
1648
是歷經很長一段時間的試驗及失敗後才得到的。
04:02
A far more effective way to create forms, I have found,
78
226640
3216
我發現到，一個較有效的形態創作法，
04:05
is to use information that is already contained in forms.
79
229856
3888
是利用形體本身已存在的素材。
04:09
A very simple form such as this one actually contains
80
233744
2655
像這一個非常簡單的形體，
04:12
a lot of information that may not be visible to the human eye.
81
236399
3592
實際上，含有許多肉眼可能不能看見的素材。
04:15
So, for instance, we can plot the length of the edges.
82
239991
2481
舉例來說，我們能標繪邊長，
04:18
White surfaces have long edges, black ones have short ones.
83
242472
3336
白色區塊部份是長邊；黑色區塊則是短邊。
04:21
We can plot the planarity of the surfaces, their curvature,
84
245808
3577
我們能夠標繪表面的平坦性、彎曲度、半徑範圍
04:25
how radial they are -- all information that may not be
85
249385
4087
以及半徑－而上述所有資料
04:29
instantly visible to you,
86
253472
1947
或許並非馬上可以看見的，
04:31
but that we can bring out, that we can articulate,
87
255419
2425
但我們能把它們拿出來、把它們闡釋、
04:33
and that we can use to control the folding.
88
257844
3376
把它們這些資料用來控制摺疊的方式。
04:37
So now I'm not specifying a single
89
261220
1959
因此，我現在不再特定一個單一比例
04:39
ratio anymore to fold it,
90
263179
2176
去作摺疊，
04:41
but instead I'm establishing a rule,
91
265355
2552
而是建立一套規則，
04:43
I'm establishing a link between a property of a surface
92
267907
2436
在平面特性與
04:46
and how that surface is folded.
93
270343
2973
與摺疊方式之間建立一個連結。
04:49
And because I've designed the process and not the form,
94
273316
2951
由於，我設計的是過程，而非形體本身，
04:52
I can run the process again and again and again
95
276267
2322
所以，我可以一而再地運用此過程
04:54
to produce a whole family of forms.
96
278589
2535
創作出一整組形體。
05:09
These forms look elaborate, but the process is a very minimal one.
97
293385
4443
這些形體看起來非常複雜，但過程卻極其簡單。
05:13
There is a simple input,
98
297828
1129
只要一個簡單的輸入，
05:14
it's always a cube that I start with,
99
298957
1952
我永遠從一個立方體開始著手，
05:16
and it's a very simple operation -- it's making a fold,
100
300909
3576
然後是一個簡單的運作－開始摺疊，
05:20
and doing this over and over again.
101
304485
3952
並一直不斷的重複。
05:24
So let's bring this process to architecture.
102
308437
2280
現在，將這套過程運用在建築學上，
05:26
How? And at what scale?
103
310717
1600
怎麼做？到何等規模？
05:28
I chose to design a column.
104
312317
1728
我選擇設計圓柱。
05:29
Columns are architectural archetypes.
105
314045
3376
圓柱是建築學的原形。
05:33
They've been used throughout history to express ideals
106
317421
3067
從古至今，皆可看見圓柱被運用來
05:36
about beauty, about technology.
107
320488
5075
表現美學概念或工藝手法。
05:41
A challenge to me was how we could express
108
325563
1922
而我面臨的挑戰是，
05:43
this new algorithmic order in a column.
109
327485
3296
如何將這創新的演算模式套用於圓柱的創造。
05:46
I started using four cylinders.
110
330781
2984
我先從四個圓柱著手，
05:49
Through a lot of experimentation, these cylinders
111
333765
3776
歷經無數的實驗，這些圓柱
05:53
eventually evolved into this.
112
337541
3135
最後變得像現在這樣。
05:56
And these columns, they have information at very many scales.
113
340676
4616
而這些圓柱處處充滿著可供運用的資訊。
06:01
We can begin to zoom into them.
114
345292
2518
我們可以靠近一點來看。
06:03
The closer one gets, the more new features one discovers.
115
347810
3555
越靠近看，越能發現新的特色。
06:07
Some formations are almost at the threshold of human visibility.
116
351365
3672
有些結構幾乎是肉眼看不見的。
06:10
And unlike traditional architecture,
117
355037
1952
而且不像傳統的建築結構，
06:12
it's a single process that creates both the overall form
118
356989
2784
這是一個兼具總體構造及精細外觀處理的
06:15
and the microscopic surface detail.
119
359773
5345
和精細外觀的單一創造過程。
06:21
These forms are undrawable.
120
365118
2691
這些構造形式是無法被繪製的。
06:23
An architect who's drawing them with a pen and a paper
121
367809
3376
建築師用紙筆描繪它們時，
06:27
would probably take months,
122
371185
1792
可能要花上數個月的時間，
06:28
or it would take even a year to draw all the sections,
123
372977
2384
甚至，也可能花上整年時間才能描繪所有區塊。
06:31
all of the elevations, you can only create something like this
124
375361
2304
透過演算規則，你只能得到像這樣的
06:33
through an algorithm.
125
377665
2136
的立視圖。
06:35
The more interesting question, perhaps, is,
126
379801
2032
但更有趣的問題，或許是
06:37
are these forms imaginable?
127
381833
2629
這些形式是否能想像出來？
06:40
Usually, an architect can somehow envision the end state
128
384462
2635
通常，建築師能夠多多少少預視一些
06:42
of what he is designing.
129
387097
1864
他的設計物件最終的樣貌。
06:44
In this case, the process is deterministic.
130
388961
2825
但在此，這個預視方法是確切的。
06:47
There's no randomness involved at all,
131
391786
2359
其中完全沒有隨機不可測之處，
06:50
but it's not entirely predictable.
132
394145
2007
但又非全然可測。
06:52
There's too many surfaces,
133
396152
1576
有太多的面向，
06:53
there's too much detail, one can't see the end state.
134
397728
3610
有太多的細節，讓人無法一窺最終全貌。
06:57
So this leads to a new role for the architect.
135
401338
3214
因此，這給建築師們帶來一個新角色。
07:00
One needs a new method to explore all of the possibilities
136
404552
3611
建築師需要一個可以綜觀所有可能的新方法
07:04
that are out there.
137
408163
1776
可以立即使用
07:05
For one thing, one can design many variants of a form,
138
409939
3232
一個人可以為一個形體設計各種可能性，
07:09
in parallel, and one can cultivate them.
139
413171
2214
同樣地，他也可以創造它們。
07:11
And to go back to the analogy with nature,
140
415385
2248
現在回到自然界的相似性，
07:13
one can begin to think in terms of populations,
141
417633
2496
可以想想人口問題，
07:16
one can talk about permutations, about generations,
142
420129
3528
可以談談世代交替、
07:19
about crossing and breeding to come up with a design.
143
423657
4863
談談想法交流延伸最終得出一個設計。
07:24
And the architect is really, he moves into the position
144
428520
2385
而建築師事實上，一如交響樂家，擔負起
07:26
of being an orchestrator of all of these processes.
145
430905
3432
總合這些所有過程的職責。
07:30
But enough of the theory.
146
434337
2344
但說夠了理論。
07:32
At one point I simply wanted to jump inside
147
436681
2527
有一度我真想跳入
07:35
this image, so to say, I bought these red and blue
148
439208
3829
這個影像。這麼說吧！我買了這些紅色藍色的
07:38
3D glasses, got up very close to the screen,
149
443037
2936
3D眼鏡，非常非常貼近螢幕，
07:41
but still that wasn't the same as being able to
150
445973
2072
但這還是和可以
07:43
walk around and touch things.
151
448045
2352
四處走動觸摸東西的感覺不一樣。
07:46
So there was only one possibility --
152
450397
1903
因此，只剩一種可能－
07:48
to bring the column out of the computer.
153
452300
3097
把圓柱從電腦裡拿出來。
07:51
There's been a lot of talk now about 3D printing.
154
455397
2920
現在有很多人談論3D輸出。
07:54
For me, or for my purpose at this moment,
155
458317
2959
對我，或是對我當下目的而言，
07:57
there's still too much of an unfavorable tradeoff
156
461276
3082
一方面，在規模上，另一方面，在解析度和速度上，
08:00
between scale, on the one hand, and resolution and speed, on the other.
157
464358
6783
還是有著太多無法兩全其美的缺點。
08:07
So instead, we decided to take the column,
158
471141
2257
與其如此，我們決定把圓柱
08:09
and we decided to build it as a layered model,
159
473398
2439
當成一個層層疊疊的結構物，
08:11
made out of very many slices, thinly stacked over each other.
160
475837
4128
用很多薄片，輕輕地堆疊建立。
08:15
What you're looking at here is an X-ray
161
479965
1897
你現在看到的是剛才那根圓柱
08:17
of the column that you just saw, viewed from the top.
162
481862
2775
由上而下照的的X光片。
08:20
Unbeknownst to me at the time,
163
484637
2000
因為我們只見過圓柱的外觀，
08:22
because we had only seen the outside,
164
486637
2376
所以我那時並不知道，
08:24
the surfaces were continuing to fold themselves,
165
489013
2160
表面會持續地自我摺疊
08:27
to grow on the inside of the column,
166
491173
2264
在圓柱的內裡延展，
08:29
which was quite a surprising discovery.
167
493437
2546
這是一個十分讓人驚訝地發現。
08:31
From this shape, we calculated a cutting line,
168
495983
3614
我們在這個形狀上計算了切割線，
08:35
and then we gave this cutting line to a laser cutter
169
499597
3024
然後把它輸入雷射切割機來做切割，
08:38
to produce -- and you're seeing a segment of it here --
170
502621
3814
你在這裡可以看到其中一部分，
08:42
very many thin slices, individually cut, on top of each other.
171
506435
4891
許多單獨裁切的薄片，堆疊在一起。
08:49
And this is a photo now, it's not a rendering,
172
513480
2813
這是最後的成果照，絕非造假，
08:52
and the column that we ended up with
173
516293
1800
而我們大費周張後得到的圓柱，
08:53
after a lot of work, ended up looking remarkably like the one
174
518093
3047
看起來就和我們在電腦中
08:57
that we had designed in the computer.
175
521140
3710
所設計的一模一樣。
09:00
Almost all of the details, almost all of the
176
524850
2121
幾乎所有的小細節、
09:02
surface intricacies were preserved.
177
526971
3040
幾乎所有的複雜處都被保留了下來。
09:08
But it was very labor intensive.
178
532626
2346
但過程非常耗費人力。
09:10
There's a huge disconnect at the moment still
179
534972
2401
在虛擬和實體間也仍舊
09:13
between the virtual and the physical.
180
537373
2760
存在著巨大的差距。
09:16
It took me several months to design the column,
181
540133
2126
我花了好幾個月來設計這個圓柱，
09:18
but ultimately it takes the computer about 30 seconds
182
542259
2718
卻只花了電腦大約30秒時間
09:20
to calculate all of the 16 million faces.
183
544977
2848
就計算出了圓柱上全部一千六百萬個表面。
09:23
The physical model, on the other hand,
184
547825
1961
另一方面，實體的模型
09:25
is 2,700 layers, one millimeter thick,
185
549786
4208
總共有2,700層、一釐米厚、
09:29
it weighs 700 kilos, it's made of sheet that can cover
186
553994
4147
總重七百公斤、平展開來足以
09:34
this entire auditorium.
187
558141
2138
鋪滿這整間演講廳的圓片。
09:36
And the cutting path that the laser followed
188
560279
2088
雷射切割機來來回回所切割的總長
09:38
goes from here to the airport and back again.
189
562367
5117
等於是這裡到機場的來回距離。
09:43
But it is increasingly possible.
190
567484
1749
但這愈來愈可能做到了。
09:45
Machines are getting faster, it's getting less expensive,
191
569233
2611
機械速度越來越快，也越來越便宜，
09:47
and there's some promising technological developments
192
571844
2760
還有一些極具展望的科技產品
09:50
just on the horizon.
193
574604
1783
正逐漸展露頭角。
09:52
These are images from the Gwangju Biennale.
194
576387
3072
這些是光州美術館交換計畫的照片。
09:55
And in this case, I used ABS plastic to produce the columns,
195
579459
3524
我在這裡用的是ABS塑膠來製作圓柱，
09:58
we used the bigger, faster machine,
196
582983
1854
我們用了更大、更快的機器，
10:00
and they have a steel core inside, so they're structural,
197
584837
3057
因為裝有鋼鐵核心，所以可以用於建築，
10:03
they can bear loads for once.
198
587894
2976
足以一次承擔高工作量。
10:06
Each column is effectively a hybrid of two columns.
199
590870
2015
每根圓柱實際上結合了兩根圓柱。
10:08
You can see a different column in the mirror,
200
592885
3409
你可以在鏡子裡看到另一根不同的圓柱，
10:12
if there's a mirror behind the column
201
596294
2050
如果圓柱後面有一面鏡子的話，
10:14
that creates a sort of an optical illusion.
202
598344
3072
就可以創造些許視覺錯覺。
10:17
So where does this leave us?
203
601431
1831
所以這告訴我們什麼？
10:19
I think this project gives us a glimpse of the unseen objects that await us
204
603262
4468
我認為這個計畫讓我們
得以一窺原本不可見的事物，
得以一窺原本不可見的事物，
10:23
if we as architects begin to think about designing not the object,
205
607730
3883
如果我們這些建築師可以開始思考，
10:27
but a process to generate objects.
206
611613
3393
如何設計產生物體的過程，而非設計物體本身。
10:30
I've shown one simple process that was inspired by nature;
207
615006
3273
我今天展示了一種借鏡於大自然的簡單方法
10:34
there's countless other ones.
208
618279
2848
還有許許多多種其他創造法。
10:37
In short, we have no constraints.
209
621127
3447
簡單來說，我們毫無所限。
10:40
Instead, we have processes in our hands right now
210
624574
3570
現在擁有的，反而是
10:44
that allow us to create structures at all scales
211
628144
4581
讓我們能夠創造各種
10:48
that we couldn't even have dreamt up.
212
632725
3032
之前連想都想不到物體的方法。
10:51
And, if I may add, at one point we will build them.
213
635757
4819
最後，容我再說一句，
早晚，我們也將會建造出它們。
早晚，我們也將會建造出它們。
10:56
Thank you. (Applause)

ABOUT THE SPEAKER
Michael Hansmeyer - Computational architectMichael Hansmeyer is an architect and programmer who explores the use of algorithms and computation to generate architectural form.
Why you should listen
Classical architecture is defined by "orders" -- ways to connect a column to a building, to articulate the joining of materials and structural forces. Colloquially, these orders are based on elemental forms: the tree trunk, the plank, the scroll, the leaf. Michael Hansmeyer is adding a new elemental form: the subdivision algorithm. He turns his math and programming skills to making ornate, organic, hyperdetailed columns generated from lines of code and then comped up in cross-sections of cardboard, almost as if they're being 3D printed.
His recent work with cupolas and domes is even more mesmerizing, like looking deep inside an organic form of near-unbearable complexity. See images at digital-grotesque.com >>
