Case Study 2.4 Minimal Surface（极小曲面）System

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
虽然感觉parametric urbanism还没有讲完，但是觉得这个暂时更有意思一些，parametric urbanism以后再补充吧

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
Minimal Surface也算是很经典的system了，运用也非常广泛，比如伊东丰雄的台中艺术中心就是Minimal Surface的一种。Minimal Surface System本身也可以分成很多种类，比如

Costa's minimal surface，
Gyroid minimal surface，
悬链面，
螺旋面，
Scherk 曲面，
Enneper 曲面。

不同种类的Minimal Surface被广泛的运用在不同的地方，比如Costa's minimal surface和Gyroid minimal surface给建筑师提供了极其有趣的特殊空间逻辑和结构特性（伊东丰雄的台中艺术中心就属于这类）。

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
首先Minimal Surface相关的基本定义：

平均曲率

“在微分几何中，一个曲面 S 的平均曲率（mean curvature）H，是一个“外在的”
弯曲测量标准，局部地描述了一个曲面嵌入周围空间（比如二维曲面嵌入三维欧
几里得空间）的曲率。

这个概念由索菲·热尔曼在她的著作《弹性理论》中最先引入。”

Minimal Surface(极小曲面)

一个极小曲面是所有点的平均曲率为零的曲面。

极小曲面的一个推广是考虑平均曲率为非零常数的曲面，球面和圆柱面就是这样
的例子。Heinz Hopf 的一个问题为是否存在曲率为非零常数的非球面闭曲面。球
面是惟一具有常平均曲率且没有边界或奇点的曲面；如果允许自交，则存在平均
曲率为非零常数的闭曲面，Wente 在1986年曾构造出这样的自交环面(陈维桓
2006, 4.6节)。

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
下面是几种空间上很有趣的Minimal Surface System

Costa-Hoffman-Meeks Surface

Lopez-Ros No-Go Theorem

Planar Enneper

Scherk with Handle

Karcher JD Saddle tower

Karcher JE Saddle Tower

关于Minimal Surface System的例子有很多，而且不同的Minimal Surface System有完全不同的应用。这次的例子集中在Costa's minimal surface System或者类Costa's minimal surface System中（因为我个人比较感兴趣这些System提供的空间）。
////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Example 2.4.1 Hybrid Space（Design by TME）

YME 是由三个人组成的Group，Yevgeniy Beylkin (USA), Margarita Valova (BUL), & Elif Erdine (TUR). （现在三人都在Zaha的事物所工作）下面的例子是2006年他们在AA DRL的毕业设计

他们的project在research阶段主要使用软件是Mathematica, 一款基于C语言的数学模型绘图软件

第一部分：Research

他们做了大量的关于Minimal Surface System的research（虽然Minimal Surface System不是他们发明的，但是我个人认为DRL这种做大量research的精神是非常值得肯定的，他们最终产出的结果往往只占他们表达的一小部分，而且最终精彩的部分往往是过程而不是结果）

Level surfaces are surfaces that represent the solution to scalar-valued functions of three independent variables.

The three independent variables can be thought of as the X, Y, and Z coordinates of a point in three-dimensional Euclidean space.1For YME, the most interesting level surfaces are the triply periodic minimal level surfaces (TPMLS) which are periodic in all three dimensions. The periodic surface divides the volume into two congruent non-intersecting subvolumes. Each of the subvolumes forms a continuous network inside the whole system. If there are two such continuous subvolumes the structure is called bicontinuous. In a more complex situation, when there are two triply periodic surfaces inside the system they divide the space into three congruent non-intersecting subvolumes and hence such structure is called tricontinuous.2 Structures containing more than two continuous subvolumes such as tricontinous, quadracontinous, etc., are generally classified as polycontinuous for their complexity.

The Triply Periodic Minimal Level Surfaces are minimal for they have zero mean-curvature at all points. While most minimal surfaces are self-intersecting, the TPMLS on another hand are without self intersections.3 This unique quality of spatial organization in the TPMLS forms the bases for YME’s research. In this section, most common families of the TPMLS, the D, G, iWP, N, P, and P_W are briefly explained and then mathematically mixed with each other to produce new surface families.

The blue and yellow colors illustrate the 2 interweaving, non-intersecting spaces in each module of the Triply Periodic Minimal Level surfaces.

YME investigates the architectural qualities of the Triply Periodic Minimal Level surfaces in order to transform this family of geometries from an architectural diagram into an occupiable space. In this respect, we have been optimizing the sections and surface areas of these surfaces in 3d modeling programs without losing their descriptive qualities.

In the following diagrams, surfaces were imported from Mathematica both with high and few amount of points, thereby resulting in smooth or mesh geometry. Each surface module, spanning between 0 to 2Pi in 3 directions, was cut in 0, Pi/2, Pi, 3Pi/2, and 2Pi coordinates.

The diagrams exploring the surface area studies focused upon the occupiable space that can be inhabited, by manipulat¬ing the surface areas in 3d modeling programs.

The yellow and blue colors illustrate the 2 interweaving, non-intersecting spaces in each module of the Triply Periodic Minimal Level surfaces.

In this section, most common families of the (TPMLS) are mathematically mixed with each other to produce new surface families. Level surface equations have the convenient property that they can be mixed with each other to produce new surface families. In the experiments depicted in this section, the Triply Periodic Minimal Level Surfaces are used as terms in the equations, creating surfaces that maintain properties of both terms. For a given pair of such terms, a 2-parameter family can be generated by parameterizing the equation with variables s and t as,

0 = s*term1 + (1 - s)*term2 + t;

so that s gives the relative weights of the two terms and t gives an offset.

This morphing technique is named as Mixing of Terms.

Hybridization is a further investigation on the manipulation of Triply Periodic Minimal Level Surfaces described in Morphing section. YME explores Triply Periodic Minimal Level Surfaces as a potential architectural diagram for spatial organization. In this regard, it is crucial to gain control over the parameters of these geometries with the aim of understanding their properties and capabilities. The Method of Mixing Terms explained in Morphing section has been a start in manipulating TPMLS by mixing the terms of various surfaces with the addition of a new parameter, s. In this section, the manipulation of the parameters in the functions of TPMLS and the functions obtained by the Method of Mixing Terms has been advanced by introducing new variables into the existing functions. The new variables can be named as the basic mathematical functions, namely the Square Root, Exponential, Natural Logarithm, Factorial, and Absolute Value. These functions have been inserted in various places in the existing TPMLS functions, thereby creating a range of geometries that individually have unique properties. By exploring how these new variables manipulate the surfaces when inserted in specific parts of the functions, YME has begun to understand the techniques of having full control over the TPMLS.

Progression towards Hybrid Species shows the process of creating spatial differentiation within the TPMLS. The main aim of the series of operations displayed here has been to break the regularity of the pure TPMLS and to create spatial richness reached through topological differentiation. For this purpose, YME has conducted a progression of operations with the TPMLS, namely Adding, Multiplying, Mixing of Terms, and Combinations, which have given way to the discovery of the Hybridization operation. Basically, Hybridization means the insertion of a function inside the variables of a TPMLS. This method, which does not exist in any of the previous operations, has been very significant in controlling the topology of the TPMLS. More explicitly, this control has been gained by the realization of what type of function should be inserted in which variable of the TPMLS formula.

In the following diagrams, the Gyroid (G) and Diamond (D) surfaces has been used as examples in explaining the operations that have been described above.

Diamond logx^2:1/y^2 specie analysis.

The names of the Hybrid Specie surfaces in the following 3 diagrams have been given according to which mathematical functions have been used to hybridize them.

General space organization based on tetrahedronal component structuring.

第二部分：Iteration 01

For YME, the characteristics of the occupied site have been the main trigger for organizing the spatial layout of Iteration 01. The site can be mainly defined as rooftops and a limited spot at the ground level that acts as part of a courtyard. The circulation core is the only element of the building that is connected to the ground serving as the main entrance. All the subsequent spaces located at the rooftops gradually morph horizontally from the vertical circulation core. The main method used for generating the surfaces is ‘Mixing of Terms’, where 2 TPMLS surfaces are used as terms in the following equation, 0 = s*term1 + (1 - s)*term2 + t. The equation produces surfaces that maintain properties of both TPMLS terms.

Stage 01. Step 01: Define Grid. The massing boundary of the proposal is built from a mathematically defined grid. The whole grid can be subdivided into cubes having 3.14 (Pi) meters dimension. All the surfaces continuously follow the subdivisions of the grid, pointing out to the cellular nature of the TPMLS surfaces. The grid is created according to the site constraints as well the spatial potentials of the TPMLS surfaces.

A closer perspective view showing the defined grid for Iteration 01.

Stage 01. Step 02: Generate Surfaces. The TPMLS surfaces are connected by the ‘Mixing of Terms’ method. Each surface fits in the accompanying subdivision of the mathematically defined grid.

A closer perspective view showing the TPMLS surfaces inside the grid.

Stage01. Step03: Deform the Grid & the Surfaces. The last step is to adjust the grid and thus the TPMLS surfaces inside it according to the physical boundaries of the site. In this way, Iteration 01 fills in perfectly the residual spaces between the existing constraints of its location.

A closer perspective view showing the adjusted grid and the TPMLS surfaces for Iteration 01.

We approach Wolfram Research and GymBox as 2 opposing worlds that collide, with 2 contrasting briefs and spatial needs. In this respect, the above diagram and the following diagram form the basis of organizing Wolfram Research and GymBox spaces. This diagram analyzes the types of TPMLS modules and their possible connections. There are basically 2 types of TPMLS modules: 1. Bicontinous spaces are formed by the Gyroid and Diamond surfaces that create 2 distinct spaces within 1 module. 2. Single spaces are formed by Neovius, iWP, and P surfaces that create 1 space within 1 module. These surfaces create interweaving spaces when several of them connect with each other.

This diagram hints at the site specific organization of the TPMLS surfaces in the vertical and horizontal directions. Surfaces with bicontinuous modules form the vertical core of Iteration 01, creating spaces where the 2 programs, Wolfram Research and GymBox, collide. This core then expands in the horizontal direction, morphing into surfaces with single modules. Surfaces with single modules act as spaces where Wolfram Research and GymBox can exist independently from each other. Thus, the vertical and horizontal organization allows both coexistence and independency for the programs.

第三部分：Iteration 02

Stage01: Distributing Space.

In order to achieve volumes with different heights inside the main building block in vertical direction, the grid is divided in sections as follows: 2Pi, 3Pi, 2Pi, 4Pi. Through out the whole of the base block one overall morphing operation is applied at the beginning of the manipulation process that holds all the surfaces in one sequence. The secondary treatment is more distinctive for selected regions.

This image shows the final outcome at the end of Distributing Space process.

Stage01. Step01: Define Grid. In Mathematica to plot a surface is nec¬essary to input limits for each direction – xmin, xmax, ymin, ymax, zmin, zmax. The first step YME did to distribute and orga¬nise the spatial system into the site is to define a site-specific grid giving the overall boundaries of the space to work within. The grid is extracted in 3ds Max from the edges of the existing buildings. Once the general volume is completed it is subdivided into modules of Pi so the grid can be transferred easily into Mathematica language.

A closer perspective view showing the defined grid for Iteration 02.

Stage01. Step02: Generate Surfaces. The second step starts with subdividing the grid volume according to use, function and general program – circulation core, entrance lobbies, working areas, etc. Following the spatial requirements according to their use and the grid limits, through a lot of experiments in Mathematica, the surfaces organising the spaces are produced and exported as .dxf files to 3ds Max.

Stage01. Step03: Deform the Grid & the Surfaces. The third and final step during the distribution process is deforming the grid and the mass body of the building to a minimum in 3ds Max to adjust to the site.

Stage02: Differentiating Space. There is a clear distinction between the spatial qualities of the two organizations. GymBox in yellow is more open with large spaces that enable different ways of exercising. Wolfram Research in blue has a mostly cellular environment where the emphasis is on small teams with specialized agendas. The three entrances face the main street – the blue entrance in the middle is for Wolfram Research, and the two yellow side entrances are for Gym Box. This time Hybridising is used as a method for TPMLS manipulation which is a more complicated process comparing to Iteration One.

This image shows the final outcome at the end of Differentiating Space process.

Stage02. Step01: Offset the Base Surfaces. The first step undertaken is to offset the base surfaces created in Distributing Space process in order to define the two individual spaces for Wolfram Research and GymBox.

Stage02. Step02: Differentiate the Surfaces. At the next step an additional morphing of the offsets is performed to introduce the specific spatial characteristics addressing their use – cellular spaces for Wolfram Research and open spaces for GymBox. As a consequence the two interweaving spaces start to intersect which wasn't intended and was considered at the beginning as a failure. Later it appeared to be a positive aspect giving the two spaces the opportunity to register one another creating visual connections.

Stage02. Step03: Generate Rooftops. The third step for this stage is the distribution of seperate, not-interweaved spaces for Gym Box and Wolfram Research on the rooftops of the alongside buildings.

Stage02. Step04: Deform the Grid and the Surfaces. The fourth and final step during the differentiating process is deforming the grid and the mass body of the building to a minimum in 3ds Max to adjust to the site.

Stage03. Step01: Separate Existing Facade.
From the surfaces created during Differentiating Space process, the ones overlooking the main street are sliced. The width of these surfaces is 2Pi.

Stage03. Step02: Generate Facade Surfaces.

The facade surfaces are generated by morphing the sliced surfaces with a plane in order to achieve surfaces with different levels of closure. As can be seen in the image, the GymBox facade, shown in yellow, has more closure because exercising environments require more artificial lighting. On the contrary, Wolfram Research facade, shown in blue, has lots of openings because their working environment needs more sunlight in contrast to artificial lighting. In this way, an observer can feel that there are 2 separate yet interwoven environments in one building by looking at the facade from outside.

Stage03. Step03: Deform the Grid & the Facade Surfaces.
The same deformation that was applied to the differentiated surfaces is applied to the facade surfaces in 3ds Max, so that they adjust to the site.

Iteration 02. Exterior Perspective.

The possible symbiotic existence of Wolfram Research and Gym Box could be enhanced by interpreting Hybrid Species not just as mathematical constructs, but more importantly as architectural entities that could then prove to have unique spatial characteristics to them. The specific processes of constructing Iteration 02, namely Distributing Space, Differentiating Space, and Generating Facade resulted in a much more developed and specific architectural means for spatial organization. While Iteration 1 achieved the general distribution of Wolfram Research and Gym Box spaces, it was still not possible to read the different spatial patterns occurring in the 2 distinct companies. On the other hand, Iteration 2 clearly shows the methods that can be applied to generate 2 completely different types of spaces. The challenge here has been to be able to formulate these methods mathematically while still keeping in mind the most necessary characteristics of architecture, such as enclosures, circulation, occupiable working and exercising areas, etc.

看了这么多感觉很有意思。

其实我理解的Parametric更多是一种建筑物质化性再诠释的工具或者手段，把过去那套结构，表皮，材质，以及由此衍生的空间的划分模式全部解构，打乱。。。

整个过程好像剪纸的游戏一样，如果你不去要求一张纸最后的具象图案，只是根据自己制定的一些规则，比如先把纸折起来，比如只剪三角的空洞形状，比如不剪掉任何一片纸屑按直线平行来剪，。。。最后，再把纸打开，它会是什么样的图形以及这个图形（包括所承载的物质实体）？最后成什么样？这确实是不确定的，但过程还是可以根据人的意志来决定。

如果把建筑学理解是人类对物质世界的再构建，Parametric的的确确是又把建筑学往这个原点上拉近一步，促使人们再思考原点上的问题，可以想象一下未来幼儿园的小孩笔下的房子不再是三角形，方形和几扇小门的图画——人们可能会在意识深层改变对建筑的认识。但至于更多，如对建筑更先进一步的定义及规则似乎还是比较模糊。

我比较担心的是Parametric把建筑学边界扩大的同时，我们目前“建筑学”这门学科的意义出现某种瓦解，因为这里还没有由此产生新的游戏规则，但更要紧的是建筑物质性似乎被Parametric诠释得过于简单（从目前来看），好比生物学家学会用显微镜去观察动物植物到细胞，结果发现洋葱，河马和人类细胞到几何组成是及其相似的，醉心于自然物之形式之纯粹之美，而盲目做出一些过于狭窄的定论或于形式完美的模型或公式，但实际所有的生物在很大程度上，至少我们说有意义的很大程度上，是完全不同的生物，而我们分享其价值也有极大差别。Parametric尽管选择上可以千差万别，但其本质所构成的是更多的趋同性，一种近于纯粹形式的趋同。

所以，我对Parametric前景还是多多少少有些担心（多多少少让我想到电影《沙丘》里的巨型基地），当然无谓好坏。

Case Study 2.4 Minimal Surface（极小曲面）System

关于 Minimal Surface（极小曲面）System早在50年前就是研究，当时的建筑师身兼结构大师 Frei otto，通过肥皂泡找形最小曲面，并且在七十年代率先在慕尼黑体育场实现，在大规模的项目中，必须符合自然的建造法则，方可以变得永恒！
您所提及的Minimal Surface相对纯粹，这里的纯粹是指数学上意义，因为数学很难把握建造，以及建筑材料上本质特征，如果把这三个方面结合起来，其实就是结构形态学研究的内容了。
如果定位一些小项目的实验，玩玩是可以的。如果定位终身的职业，必须付出巨大的代价，结果是什么样，未知数。
西方的所谓前卫建筑师的成功在国内的模式很难复制，因为他们一般都有在结构上的parter。所以才得以实施。
如天津泰达广场，形态如同羊角，曲面为最小曲面，通过边界的约束，张拉而成的建筑。

我对parametric的前景担心，但是我相信在未来较短的一段时间内，这种parametric会比较吃香，因为随着技术的不断提升，人们似乎看腻了这种方盒子的建筑，尽管方盒子也在努力的千变万化，人们似乎跟需要一种变革，一种刺激，而parametric应运而生，他满足了人们这种需要刺激的需求。
但是......n年后，当满世界都是异形的建筑的时候，那个时候人们又会需要一种什么样的变革呢，也许有开始缅怀方盒子，就像美国的议会大厦缅怀古典主义一样，也许那时人们都不需要建筑了，谁知的呢。

foral先生作了很好的尝试，探索。
在关于合理性，可行性上，需要向前走一步，就需要结构形态学有很好的把握了，建筑师可以把握建筑形态学。
如果摈弃所有的建筑元素，投入到maya，rhino，GC，DP，catia，3dmax，formz以及所有的特殊的造型程序中，很容易迷失方向。

简单讲：一些自然界的物理模型才是合理，可行的方向之一，当然要注意尺度效应，不能简单scale，就把建筑拿出来。否则要付出代价，就看业主的财力了。

结构形态是结构内在本质的外在表现。它决不是孤立的结构现象，而是抽象的结构规律的形象化体现。实际上，由结构现象上升到结构理论，我们不经意地都要经过结构形态分析的环节。例如，一块岩石、一株大树、一只贝壳……都具有复杂的结构。要想对其进行力学分析，首先必须在形态上将其抽象为结构模型，并用结构简图予以表示。这种形态上的抽象就是结构形态的分析。结构形态分析得恰当、准确，接下来所作的理论分析就能够代表实际的结构现象；否则，理论分析就难以反映实际。因此，结构形态分析的重要性是不言而喻的。合理的结构形态是力学规律的外在表现，本身即蕴涵着和谐与自然，就如同贝壳的形态是出于自然、反映自然一样。决定结构形态合理与否的自然法则是能量最低原理，能量是物质存在的一种方式。一种物质结构能够相对保持一定的稳定性，就是因为它处于能量较低的状态。生命现象虽然更复杂，但能量法则对生物界同样有效。一切生物的生存全赖它对能量的获取，植物、动物、微生物无不如此。

Case Study 3 非典型parametric system

经典的parametric system很容易被用到泛滥，比如voronoi，虽然本身有它的优点，而且也可以衍生出不少的分支，但是还是会丧失原创性，而且从某种角度看这些经典的parametric system对于建筑师设计还是有很大限制的。

其实在parametric design中更多的是非典型的parametric system，而我认为非典型的parametirc system更加贴近parametric design的真正意义----拓展建筑师的自由。Frank Gehry上世纪80年代要在日本做一条“鱼”，寻遍各种软件，最终找到了工业设计领域的CATIA，借用CATIA的parametric本性。这也可以算是parametric design在建筑设计中的开始吧。所以从最开始parametric软件就是来实现建筑师那些非理性的想法的，即使你的设计结构上再不合理，就象Frank Gehry揉一团纸，parametric软件也可以从头到尾将这团纸变成建筑。很讽刺的是今天parametric design却很大程度被看作是建筑向理性的回归，希望建筑中所有的东西都要有理有据，最好还有个公式控制。

非典型的parametric system这个题目太大，讲起来也就更随意一些，看到什么project就说什么。

Example 3.1 DRL10 Pavilion(cspace)

DRL10 Pavilion是AA的为了庆祝DRL10周年而做的一个installation，先举办了一个小竞赛，然后选出了获胜作品建成实物。

进入决赛的一些作品

最终胜出者

从设计开始到最终成品是需要一个过程的，即使是有parametric工具，也无法一步到位。这是最初设计竞赛阶段的构造细节diagram，可以看出和最终还是有差距的。

设想的建造过程

电脑中的模型(Rhino+Script)，结构分为
横向

纵向

相交

座椅，这算是初级阶段的模型，这部分的结构似乎还没有完成

3d print模型

小组成员摆拍

电脑模型继续细化，任然没有座椅部分的细节

AKT似乎是小组的结构合作伙伴（AKT的网站很帅http://www.akt-uk.com/，公司也很厉害），他们决定使用叫做fibre-c的材料，材料基本尺寸是 3.6m x 1.2m ，但是最终他们选择了5m x 1.2m的fibre-c，虽然这样重量超过了UK的手动抬高限制，但是结构上更强，所以他们开始看如何把他们的结构构件lay out在5m x 1.2m的模版上

计算出每个节点的角度

座椅部分还是没有进展

关于材料， fibreC是一种混凝土加强的玻璃纤维，结合了混凝土和玻璃纤维各自的优点（抗压，抗拉）

结构小样

椅子终于有了进展

一些连接的节点

根据AKT回馈的FEM测试的结果，作出下列更改

1. 减低最高点到15度. We also lose some of the dynamic formal movement and drama of the structure.

2. 给侧面的结构增加跟多连接. This could be done by infilling flat sheets of fibre-c stiffeners between profiles at various locations. This could also detract from the visual and structural purity of the pavilion.

3. 增加跟多的主要结构构件. This might alter the visual effect of the moire pattern, but could also be interesting if done as a gradient of spacing. I also find it interesting to architecturally express where the structure is performing the most.

4. 加厚材料13mm, and decrease thickness of material at secondary profiles to 10mm (reducing the self-load).

结构小样制作，CNC切割

组装

终于的，9步来组装一个AA DRL10 Pavilion
