Though Mark Fornes and Atelier Calter do not disclose the generative process, it is plausible to assume that there might have been trials to optimise the amount and direction of said control points/lines so that their usage is effitfrom sphere to sphere seamlessly.
Of course, with enough scored lines and bending moments, the project would have achieved the perfect specimen of smooth edge and continuity – a symmetrical platonic sphere that holds a simplified structural unity. However that would diminish greatly from the sense of visual continuity and the language of morphology.
An idea explored by Robert Woodbury in his ‘How do Designers use Parametric Design’ is that there’s a typology of parameter – in this case visible as the juncture between elements and the overlapping of two directions of patterns and interaction of double curvature (aimed to further the complexity of shape)
– and the guidelines for actual form – the size of the spheres, the degree of vault. Once conditions at which the shapes are conjoined and the relationships between different sizes of spheroids are established, the rhythm, the logical law by which folding as a technique controls the bending point and junction, is derived.
TECHNIQUE EXPLORATION | FOLDING The conventional understanding of folding is as that of a technique that defines edges, tessellates the connection points between surfaces. Folding is, in essence, a point of distortion on a plane, a point of stress on a surface. This goes around to imply that it’s a technique necessary to achieve any geometry. If we fold a square piece of paper, it will become a triangle, if we fold it on pre-calculated seams, we’ll have paper models of platonic solids, and so on.
The shapes can then be stacked
and reapplied over and over to create a continuous surface and structural vaulting over a span dictated by independent factors – such as the site or installation space area and height, designated usage of space, and amount of open large vaults required.
DoubleAgentWhite,anexperimentalstructureconsisting of developable combination of spheroids, explores how folding interacts with morphology of geometry and surface outlines where they meet. One of the constraining parameters of Double Agent White would have been to develop a surface that allows for curvature with angles that would allow protrusion, yet flows into itself smoothly. Scored and folded lines serve as control points through which the folding occurs. 4

The dA Office (MoMA, 1998) was designed by Nader Tehrani and Monica Ponce de Leon of NADAA, and aims to deconstruct the mainstream definition of facade and structure. This is, in essence, a developable surface held by itself and column-like supports, draped over an existing building.
B1 - TECHNIQUE STUDY
FABRICATING COINCIDENCES
Here the folding also is responsible for
granting the structure its structural quality.
Thebend/foldlinesandthetriangulationedges between the strips of steel create stress points and give the vertical span some rigidity and stability.
Structural columns through
which the folding is continued assist this notion. This makes the metal sheet both the structural component bearing its weight, and the aesthetic/decorative function prescribed
to the ‘skin’, thus blurring the line between the two
(MoMA).
The definitions of folding here are all achieved through principles of computation
– defining each individual ‘face’ of the strip as well as the strip itself, perforating the surface to let light through, determining the overlap and scoring the edges. The technique of score and fold rather than bend under direct stress, or welded/bolted joints challenges both the qualities of materials and perception of assembly. Why go through the length of actually folding the material as opposed to imitating the folding pattern?
The elimination of joints prevents needing to apply additional material and causing thicknesses at each joint, which in turn lets the folds to look more clean-cut and executed with much more precision. There’s also less risk of the metal failing under stress, seeing as some of it is relieved by the scoring.
7
Once again, there is a focus on continuity through the shape, the fact that the ‘folding’ seam is indeed the procession of one surface into the other as opposed to disjointment and fracture of the face.
8
B1 - TECHNIQUE STUDY
In the Botswana Innovations Hub (Shop Architects), currently in construction, this quality spans through the entire building. The facade of each floor is one long strip that distorts and morphs as it’s stretched over the building and loops up and down. This kind of language unites the horizontal panes of the building together, and the fact that the folded surface creates a geometry brings the whole form closer to a developable parametric form as opposed to just the facade.

BIOTHING REVISITED
Seroussi pavilion by biothing, previously mentioned in ‘biomimicry’, is a conceptual competition entry that focuses on automated interaction between elements, reaction to present charges, self-organisation and
morphologies of geometry to achieve new form.
It’s almost like the linework created in the x | y panes is being pushed from the edges to bend upwards and create the little pods. This is a very interesting generative feature and provides a mix of control over the initial input for element arrangement, and novelty, an element of predictability as there is no knowing how that initial basis will distort and morph in

that will organise lineworks engaging with each element and self-organising as defined by attraction/repulsion generated by the force fields.
second, there is a folding/bending sequence in the materiality and expression of said form. the pavilion model seems to consist of thin strips fixed together at the common point – the very top of the ‘domes’, and then
the tectonic application of folding in this

SELECTION CRITERIA 1)
To be visually dynamic, that is, to have the visual elements producing a sense of rhythm or
movement, some sort of fluxuation. It is the dynamic and repetition of unified yet differing elements that
Seroussi pavilion so aesthetically pleasant. To retain its attributes as a three-dimensional shape. all geometry that is nothing but flat strips will be eliminated as it doesn’t have any structural or architectural application. 3) Plausable real-life application or structural suggestion make
2)
The case study is firmply rooted in point charge and attractor points so it was exciting to break apart that pattern and produce a new arrangement. there is the aforementioned movement and rhythm not only in repetitions of lines but also in how the individual shapes seem to crawl out and away from the initial frame of curves. This iteration embraces Alisa Andrasek’s idea of no confined canvas to work within - as the
GH definition changes, the shape distorts and spreads.
the introduction of a cull pattern allowed to create an intense visual dynamic and a less predictable distribution of charge points, breaking apart the circular geometry and becoming more seemingly chaotic.
Having the attractor points shifted closer to the centre really emphasises the difference in positioning depending on how far away it is from said points, demonstrates how each ‘pod’ warps as the charge effect decays - a new sense of rhythm and dynamic in itself.
this has been a succesful trial of reversing the shape and starting to think about structural values. You
can easily imagine something like a built vault system to create an enclosure, with the attractor point circumferences being the centre of weight transfer. the idea of an entire system is favourable because it shows how parametric design can be beneficial - the deriviation can be edited to accomodate column thick-
ness avaliability, the need to structural elements required etc. in terms of selection criteria, it is a very
plausable 3D shape imaginable in real life; the degree of slope and variation of each ‘pod’ is interesting and dynamic to some degree.
here a whole new methodology of pod structure has been defined, with intertwining arches and closed
curves. this is almost reminiscent of self-organisational methods. The first choice criteria indirectly hints at presence of a pattern, and compared to the other itirations, this is the most interesting and prominent change that has been achieved in the pattern. the pods are quite three-dimensional and have their presense as individual shapes, which one can imagine prefabricated and stacked together to form a dynamic whole, so a plausability of real-life application emerges.

PAPER ARCHITECTURE
a series of experiments bending a paper strip to see how it reacts under pressure. a series of control points have been employed to experiment with geometry similar to the one of loop_03. to achieve the 3-point ribbon structure, which is what the case study uses, both attractor and repulse points are in action - the ones in the centre are pushing the strips in, folding them in towards the centre; the ones around the outer curves ensure the surface retains the volume.
similarly, when a number of strips is combined, they share their control points and an amount of shearing along the z axis is added and shifted as the two pieces of geometry interact with each other as well as the pins
22
analysis of bending in the physical realm
more prominent on a thicker strip, the flat thin body of the strip is warping even
when nothing is done aside from pinning it down. folding occurs throughout the entire strip even when only three control points are employed - in other words it supports itself in a certain curveature throughout when the same kind of centralisation happens as in loop-03
similarly, the shape changes drastically and drastically moves in the x+y+z axis when the natural edges are twisted.

biothing - seroussi pavilion
approach:
distributing a number of charge points as the centres of each ‘pod’, distributing lines to define the shape and radius of each pod; using graph curvature to define the level of three-dimensional protrusion of the pods.
innovation:
new shape and unprecedented form morphing from minimal parameters set by human; everything else is derived from a grasshopper definition.
self-organisational principles controlled through a set of variables and definiion factors, almost akin to biomimicry.
aesthetic:
rhythmic, reaching out, dynamic, ballanced, symmetric (despite slight assymtery), flowing, interconnected, harmonous, sensual, serene
parametric design advantages:
unprecedented form, interesting folding/bending moments that are otherwise impossible to control
24
co-de-it - loop_03
approach:
extruding base set of geometry to create a set of curvatures and developables that will have structural integrity thanks to the tension and stress distributed by this percise curvature.
innovation:
usng a mathematic formula, a sine graph, to define the flowing geometry, to define scale and spacing; to employ algorithms defined by curvature (sin, cos, tan) to set the parameters for an optimal form. this engages both generative computation and human intelligence to pick the most pleasant outcome.
aesthetic:
dynamic,flowing,morphologic,untangible,uncontainedwithinhorisontalandverticalpanes,organic, fluid, centered, uncontained, ethereal parametric design advantages:

selection criteria
1)
To employ the mechanic of generating new geometry and form through sine curvature in an aesthetically pleasant unprecedented manner that can be expressed in an algorithm and applied to a variable set of parameters. one can speculate that the parameters, such as the base geometry, the maximum verticality or horizontality and other features, can be directly taken from site and brief context, thus combining the power of generative computation design and the need to grant it contextual and metaphysical value and unique site relevance. 2)
To have a sense of movement and rhythm expressed through its visual elements, to possess a certain con-
tinuity, as this is more plausible in a circulation device and would complement the creek flow nicely. Sines rotating around a fixed centre point are at a disadvantage here because their circumference becomes its own limitation to said continuity.
one can speculate that the parameters, such as the base geometry, the maximum verticality or horizontality and other fea-
tures, can be directly taken from site and brief context, thus combining the power of generative computation design and the need to grant it contextual and metaphysical value and unique site relevance.
3)
To explore negative and positive space, the dynamic of solid and void; to be perceivable as a 3-dimensional flux shape yet not be solid. this has been a feature intertwined with the basis of generative design through sine curvature - making flux form beyond the limitations of generic panes and orientations through something that is technically not a solid (the concept of developable surfaces challenges the perception of platonic solids at its core). Therefore, to keep this un-whole-ness, the extrusions cannot have immaculate presence, there needs to be a dynamic of positive and negative spaces. As potential on-site application, this can be effective dealing with issues identified in part A, such as waver level variations and pollution sweep. the openings let water pass freely, and could function as a filtering device akin to baleen.

selected species The raft species comply with deconstructing the centring around one attractor point, which was a first coming out of the Loop-3 reverse engineering. Sine curvature creates a repetition of plates that are almost sort of like a pathway in the middle; the repetition creates a sense of flow and rhythm in the geometry, like little waves in themselves. In terms of technical application, one can imagine an extended sequence forming a paving or a bridge of sorts.
There is something very expressive and moving in this particular shape, and the full asymmetric curvature is aesthetically pleasant. Point 3 is really challenged here because this iteration above all presents a solid shape, a three-dimensional presence; and out of all it has the least surface coverage seeing as all expression of form is expressed through the use of curve, no extrusions or lofts. Though the influence of the sine wave is still readable in the initial form, the outcome of rebuilding arcs – the kinks, the radius and behaviour - was quite unexpected and exciting.
This species has been selected because it gives an impression of scoring a solid shape, of introducing openings into the whole as opposed to trying to make up a flux shape from smaller elements, in this technique extruded strips. There is also a more or less defined system of longer, curvier elements resting on top, and harsher arches of strips at the bottom, which makes one think of structural frames vs exterior expressive curvature, giving room to make speculations of real-life application of something like this.
The folding mechanic here is a kind of folding novel to Biothing and Loop-3 – sharp, angular, pronounced. It’s a stark contrast with the smooth curvature of other itirations and the original case study, and would be of equal contrast juxtaposed with the natural environment of Merri Creek, but perhaps the contrast would work to emphasise the rhythmic, dynamic presence of the shape. The tectonics of creating 3D form from bending a single piece of material in different directions is quite interesting; but while this method of surface treatment can easily be used for all kinds of surfaces, it lacks in the innovation/unprecedented behaviour department.

proposal the aim is to engage with generative design principals previously explored. the use of sine curvature has proven
the direction to formulate this proposal was as follows:
itself to be a tool to create new geometries and shapes that are aesthetically pleasant, mirror the dynamics of
the site, and can have an application to engage the two banks and the waterway by creating a bridging structure.
bending and folding to create curvature means a variation in levels, making this technique very applicable to a) be able to be placed in varying topography such as the steep banks of merri creek, and b) actively engage with such site
conditions, the height and positioning of anchor points inevitably affecting the geometry.

separation of the shape into strips and gaps between the strips as seen in both biothing and loop -3 would create a shape that has qualitative functions of transparency and lightness, very suitable for a site that is desired to be

> to experiment with the algorithm parameters to produce the most ideal iteration. refer to past selection criteria as well as fullness, harmony and wholeness of form produced. these are, of course, pure speculation at this point, beginning to introduce a functional logic that would need to be solidified and refined over and over again before it can be considered physically applicable.
there are three shapes present, unique but very similar. the lower sweep separates the body of
the speculated bridge from oncoming waters and currents, acting as a breaker in case of flooding and a barrier for large particles of rubbish.
the middle curves, analogous on both sides, are
the body of the bridge, and would be the main loadbearing elements.
the outer curve is a visual counterweight to the other protrusion and allows a smooth transition from artificial proposal to waterline.
49
proposal
the form expression through layering individual elements and creating a play of opening and whole resolves the two secondary problems - in the case of flooding, water would be able to pass freely,
without stagnating or ‘dambing’. large elements of pollution, however, would get caught on the lower curves and make the cleaning process easier.

resolving current stagnations
here’s something to consider before part c commences...
Materiality Each material behaves differently, especially so if exposed to stress (such as bending and folding processes) and load (inevitable in a bridge structure). It is therefore fruitless to estimate capabilities to hold shape and obey by a certain direction/parameter without an indication of how a chosen material will behave. steel seems an easy choice from the top of one’s head but there’s always environmental concerns and costs related – perhaps there is a more efficient option for materiality, such as timber that still performs well and lasts for a long time when exposed to water – materiality is a field worth researching into before starting part c. Once the choice has been made, material performance will be evaluated and prototyped properly, with consideration for connections, scale differentiations and tectonics. Structural integrity it is crucial that the proposal is given structural ground and regulation, or at least proven that it can create something so rooted in engineering and understanding load and integrity as bridges are. it would be wise to refer to existing bridge structures, whether to obtain a better understanding of loadbearing elements and requirements. Either way, | anticipate looking at new precedents and coming up with some basis for structural plausibility before part c is on the way.
proposed bridge by laurent sant-val (amsterdam) combines sine curvature and need for structural elements (eVolo)
Better side connection and consideration of scale There were significant issues with topography difference and the degree of curvature created, as well as the span grasshopper outputs compared to the distance between the two banks. direct measurements of the site would be extremely useful, prompting a site revisit, and a new, more accurate definition may need to be produced. Form expression while the current proposal has a very direct correlation to the chosen technique, it does have its disad-
vantages and risks – ensuring materiality and stability, ensuring safety concerns, accessibility and being
user friendly, gaining quantitative value as well as artistic expression and conceptual depth. It is possible that the sine curvature as a shape generator can be expressed in different manners, such as the ‘disintegration’ species – having an interesting form and employing a different or slightly modified technique to translate it into architecture. through i do not plan to make a definitive shift in this direction, it may be worth investigating if continuous issues and doubts arise with the current theme.
57
learning outcomes It was fascinating to see things previously covered in part a start to emerge in my own work – generative design, the ability to create iterations, the response of Grasshopper outputs to changes forced on the parameters. The biggest obstacle and the biggest achievement during Part B has undoubtedly been the technical side of Grasshopper. Even the transition from analogue methodologies of thinking to computational ones took some time to occur. For example, in my Loop 3 Reverse engineering, my initial idea was to imitate the bending technique of what I later discovered to be the sine curve through Kangaroo. While Kangaroo is a powerful tool for simulations and computational performances, this mindset shows my initial lack of understanding of generative processes and growth, and trying to overcome the task by imitating analogue methods. Once the principles of creating a new form from something that did not previously exist, through morphing and distortion as opposed to computisation of existing matter and slightly editing its state, it was really exciting! Once I got around to understanding data structures and basic manipulations such as shifting lists, sorting lists, singling out items in a data tree and the effects of grafting and flattening, it became much easier to control geometry and gave me a lot more control over everything I was doing. My experience with Grasshopper has been very trial-and-error, branching out for new results and realisations through things I already knew, and strengthening my understanding of certain functions through the application of such. In terms of architecture and tectonics, I admit it was a bit difficult to translate the technique to an actual plausible idea or concept, so there was a bit of what I refer to as ‘conceptual stagnation’. Playing around with paper, plastic and wire prototypes was a valuable learning tool to overcome this – it felt like conducting a dialogue between digital and paper spaces. It helped me learn to envision techniques applied to real life spaces and constraints, and to project them onto my brief and outlined problems. another learning outcome has been that of digital fabrication, understanding the constraints and resources avaliable.
What is important about fabrication and materiality is understanding real-life
industry applications as well as material properties and fablab facilities - for example the ability to 3d
print something does not mean that said something is a plausible efficient direction; and the ability to pres-
ent form does not always mean valuable prototyping. It’s important to know what exactly you’re testing for, and what inaccuracies are evident in certain prototypes (paper bridge...enough said...)
I look forward to continuing to explore grasshopper techniques and learning about translating computational outcomes into architectural elements in a way that has meaning and significance in terms of materiality and tectonics.
trying to imitate sine curvature in rhino through computisation, and through ‘bending’ a circle in kangaroo. glad we’re past that.
