091215_Mesh SubDivision



"The climber of facades must make the best use of every ornament." Karl Kraus
Moving away from the description of nurb surfaces by mean of UV coordinates this experiment represent the possibility to use mesh planes and realtive vertices to extract points and apply Delaunay algorhythm. The input surface is therefore subdivided in a serie of planar triangles which form the base for the construction of the component geometry. The components are parametrically controlled by 6 points which define the triangular component, maximizing or minimazing their surface area.

Above some images showing the build-up process:
-surface "occupation" with point cloud
-subsequent "connection" through triangulated mesh
-"population" process through planar components
Below the Grasshopper definition.

091027_Reciprocal Frames


In this exercise i continue exploring the relationship between systems and (static or dinamic) equilibrium (homeostatic serie). Reciprocal frames are structures where internal equilibrium of parts provide overall stability to the structure. My exercise is limited in exploiting the geometrical arrangement of component parts without engaging (for now) with the problem of overall equilibrium.

090824_Diatoms





Diatoms (Greek: (dia) = "through" + (temnein) = "to cut", i.e., "cut in half") are a major group of eukaryotic algae, and are one of the most common types of phytoplankton. Most diatoms are unicellular, although they can exist as colonies in the shape of filaments or ribbons, fans, zigzags, or stellate colonies. Diatoms are producers within the food chain. A characteristic feature of diatom cells is that they are encased within a unique cell wall made of silica (hydrated silicon dioxide) called a frustule. These frustules show a wide diversity in form, some quite beautiful and ornate, but usually consist of two asymmetrical sides with a split between them, hence the group name.

"VISIONS", BEYOND MEDIA 2009 - Nous Gallery


OPENSYSTEMS has been invited by Nous Gallery (Melissa Woolford) to participate to the 9th edition of BEYOND MEDIA, International Festival for Architecture and Media. This year's title is "Visions". BEYOND MEDIA is the most significant event worldwide for the presentation of architecture videos. The initiative was created in Florence by Marco Brizzi and is today in its ninth edition. It is devoted to the most current visions on architecture and to the debate on the relationship between the project and the media.
"The massive production and consumption of architectural images has resulted in a greater proximity to design issues by the general public. But at the same time, images alter the way people conceive of architecture, and they affect the ability and the opportunity to generate visions, and hence theories, that are deeply rooted in our time and, at the same time, receptive to new, possible scenarios. With "VISIONS", the BEYOND MEDIA festival (...) will propose effective visions that may be useful in constructing a framework for the future."
OPENSYSTEMS will present a video entitled "Attractor Fields" and it will be part of the Nous Gallery space in Stazione Leopolda, Florence, 9 - 17 July 2009.

090515_Attractor Field II




Above: first investigation on 2D and 3D fields; the colors in these case established a gradient which indicate the average distance of points to the attractors: color is data! the attraction can be regulated according with 2 parameters: the power of attraction and the scale factor which describes the extend of the Gaussian boundaries determined by the overlapping of two or more poles of attraction. Thanks to Panagiotis Michalatos (AKT) for C# support.

sin(WAVE)
Some images of the last (lost) competition entry for the London Tent Art Fund Pavilion 2009. sin(WAVE) is defined by two 5-degree surfaces which are modulating respectively the structural canopy and a lounge area at ground level. The surfaces are generated through a network of sine/cosine curves which are shaping a tripod structure.


sin(WAVE) addresses the pavilion requirement to negotiate between inside/outside qualities by creating a provisional structure which fluidly supply repair with its roof while offering reconfigurable settings with movable partitions (lounge-scape area, vertical wall..).



The grid shell is formed by, respectively, 55 longitudinal and 25 transversal ribs each of which can be easily fabricated with a laser cut machine. Above an internal shot of the 1:25 laser cut model. Special thanks to Andrew Payne for its grasshopper definition for waffle structural systems.

Last Lost Competition

Last (lost) entry for "ARCH+ Competition, Simple Systems - Complex Capacities"
Brief:"The design of a material system that is in exchange with is context-specific environment and that, in doing so, can fulfil functional and performative requirements."
The entry proposed a profilerated field of homeostatic cable structures addressing pluri-potential capacities such as structural, organizational, environmental and spacial ones. What is promoted is the articulation of a heterogeneous, differentiated structure.
"Without modifications to the social and material environment, there can be no change in mentalities. Here, we are in the presence of a circle that [...] postulate the necessity of founding an "ecosophy" that would link environmental ecology to social ecology and to mental ecology".(F.Guattari )

HOMEOSTATIC serie: cable nets_02


Above the Grasshopper definition of the model develop in Rhino. As it shown the model is fairly simple - controlled by few control points which can update the whole structure- but ended up being very usefull to test quickly and accuratly different geometrical configuration and to extrapolate data for structural analysis.

HOMEOSTATIC serie: cable nets_01



I'm currently doing some research into cable structures; the idea is to create some self-stabilizing cable structures where tensile elements (the cables) find a state of equilibrium through their connection in space. Initially it was thought as an interaction of rigid compressed element shaping the geometry of the structures and tensile cable; tying the cables, though, in three directions help stabilizing the structures without the need of internal compression frames. this research is intended to become a 1:1 installation but I'll talk about it a little bit later.
This initial phase has been developed with Grasshopper which seems to be surprisingly powerful, easy to use and with great potential. Thanks Rhino!


The structure is also interesting for the fact that it develops a Moire' effect through the overlapping of its cables. It creates a higher or lesser degree of transparency and visual porosity. "In physics, a moiré pattern is an interference pattern created, for example, when two grids are overlaid at an angle, or when they have slightly different mesh sizes". (Wikipedia)

Open systems: approaching novel parametric domains


Following an extract from an article featured in the new issue of VERB - From Control to Design- Parametric/Algorithmic Design coming out soon. The publication is A synthetic look at the impact of parametric and algorithmic design on architectural practice. Contributors include: Mutsuro Sasaki, Arup’s AGU, Aranda-Lasch, Michael Meredith (mos). Special thanks to Albert Ferre and Michael Kubo.
Some of the most relevant shifts in contemporary architectural discourse and practice are intrinsically connected with evolution in computation techniques and software development.
The novelty in architectural design brought forward by new computational tools is often related to software packages or digital techniques developed in other design fields. Innovations in computational as well as manufacturing processes, in fact, experimented and developed by naval, aero, automotive and products industries have represented seminal undertakings for innovation in the construction industry and, moreover, for experimentation in architectural practice.
The introduction of parametric software packages in the world of architecture and structural engineering, despite being a fairly new paradigm, is already redefining the discipline from within.
Traditional CAD products create lines, arcs, circles and a great variety of geometrical objects; making design changes to a given geometry requires changing all appropriate components in order to make the drawing correct.
A new generation of parametric design systems establishes models defined by a collection of constrained relationship between objects. In other words it allows setting up parametric geometrical arrangements capable to build anticipated variations between objects. To better understand what is a parametric set up let’s imagine, for instance, two circles whom centers are connected by a line. The length of the line is, at a time, the sum of the radiuses of the two circles. In a parametric model, varying one of the radiuses affects the length of the line and the mutual dimension of the two circles along that line.
A parameter thus is a variable to which other variables are related by means of parametric equations: design modification and creation of a family of component parts can be performed efficiently by setting up reconfigurable smart models capturing the underlying logic of the design.
The instrumentation of parametric setups into architectural practice is starting to shift the role of the architect in the design processes: from the design of specific shapes to the determination of those geometrical / algorithmic relationships describing the project and its components. The design shifts from drawing surfaces to setting up rules of interdependency - genotypes - leading to potential differentiation – phenotypes -[i].
The novelty represented by parametric tools in architectural culture hasn’t found architects unprepared to conceptually understand its potential for contemporary practice: the responsiveness by which architects and advanced design firms gathered the resources of associative design has triggered a fast implementation of parametric tools in the software industry as well as an increasing curiosity to apply its potential in contemporary architectural design.
Nevertheless, despite the receptivity of some of the most interesting cutting-edge architectural practices, it is possible to trace certain tendencies concerning different approaches, some limitations and novel developing scenarios.
Part to Whole relationship
“So far experimental architects have just jumped from top-down determination of parts to bottom-up determination of wholes.”
Greg Lynn[ii]
What
This approach, though, has just represented an extreme case. Nevertheless, reshaping the traditional dichotomy between the building and its parts, new digital parametric tools still leave behind some unexpressed potential for contemporary architecture, particularly in relation to the possibility to define highly modulated wholes together with the determination of differentiated non-standard components.
Problem-solving approach
Traditional program packages can initially develop quick and precise 3d models; at the same time any occurring change would imply rebuilding the model over and over again until a fixed determination of the design and all its aspects. This is where parametric models come into place.
Parametric design, on the contrary, despite the more complex and, to a degree, time consuming developmental logic, offers greater advantages: from accommodating unpredictable changes happening during the design process to extracting precise data for structural analysis or fabricators.
From a design point of view it is possible to imagine the advent of design methods based on codified geometrical operations proliferating and interacting to achieve a higher level of complex order: the development of a specific design vocabulary based on parametrically codified instances prefigures a fully integrated design approach where complexity and differentiation emerge from the set-up of coherent and controlled operations.
In this sort of scenario the role of the architect and that of the engineer is contiguous and inform each other in a truly cooperative and generative holistic design process.
Open System: branching structures
A second approach towards parametric design is represented by the attempt to build up a deeper understanding of structural systems as multi-performative design set-ups.
Moving away from the homogeneous standardization of the Modern paradigm, this research, through the generative use of parametric tools, is seeking to investigate open systems as multi-performing, differentiated organizational systems.
In line with the experimentation on branching structures developed by Frei Otto, the research unfolds through a series of exercises aiming to open up a generative approach to parametric design: specificity is achieved through iterative differentiation, adaptation through redundancy, robustness through structural-geometric interdependency.
Understanding architectural design as a process of formation leads to the exploration of a pre-material state of a given systems: namely, the state prior to the crystallization into a specific design form is explored. In this way, open systems act as virtual machines prior to the actualization into a given design scenario.
Methodologically, different paths are followed in an attempt to open up potentials for inclusive performance:
Organizational logic> branching is explored as an organizational system. Different network topologies are analyzed and compared.
Geometrical logic> the geometrical logic of branching is created and developed through parametric tools: Digital project is employed to generate the geometrical structure; in addition differentiation is achieved by the instrumentalization of the defining principle: angle between branches, number of branches, length, displacement of the nodes in space…
An intricate matrix is then emerging from the proliferation of differentiated geometrical operation.
Structural logic> the structure and the stability of the various configurations is analyzed through finite element analysis software [FEA]. Thus running structural analysis necessitates specifying a range of parameters to set up likely structural scenarios.
Running structural tests on differentiated geometrical arrangements is possible to detect certain general behavioral patterns happening during the process of extracting precise data for structural analysis or fabrication.
The possibility to establish interdependent relationships between different system logics contributes to the redefinition of common fitness criteria: each system logic, instead of responding to a specific optimized scenario, informs each other towards a multi parametric performing whole. Geometrical arrangements, spatial affects, structural performance and organizational logic contribute to the formation of the system and its performance-based logic.
The development of such a research shifts the architectural paradigm from a problem-solving to a problem-caring approach where integral design logics contribute to the coherent employment of novel design method.

Attractor Fields, Smart Geometry 2008

I've just got back from Munich where I've participated to the Smart Geometry 2008; it was a very interesting week of workshop and events; the Generative Components workshop has been a very intense and rewarding experience; I'd like to thanks SG for organizing the event and I look forward for next year, maybe on the West coast...
Following some images regarding the work I've been producing in four days. I've been playing around with Generative Components trying to investigate concepts related with field condition and surface population.
"Vector fields are often used in physics to model, for example, the speed and direction of a moving fluid throughout space, or the strength and direction of some force, such as the magnetic or gravitational force, as it changes from point to point." (wikipedia)
In the above diagrammatic chart is represented a field with two main attractors positioned at the vertices of the present line. The vector field gets attracted to these points according to the proximity to it. The attraction was generated by a C# script thanks to the support of Jeroen Coenders (Arup). A whole series of gradient conditions originate from such a set up and it is what makes the exercise interesting for the capacity to become an abstract differentiated machine: zones of attraction (or even repulsion), orientation, differentiation between similarity, self-similarity are just some of the interesting characteristics to be exploited and potentially applied for design.


The surface population exercise is fairly straight forward and simple to implement: in the case shown above the components that populate the surface are provided of local coordinate system. In this way is possible to orientate one axis of each single component towards an attractor point (sun?).

080205_Vertical Proliferation 2


As promised, some improvements on the previous script; this time the "vertical proliferation" operates through a better control of the points defining the overall structure.Parameters: Number of floors, number of control points defining floor plates, number of points along the perimeter of each floor plate. The current set up allow for a more precise determination of the overall geometry as well as a better control on local manipulations. the points displaced at the perimeter of each floor can be used, in fact, to further articulate the skin.
These structures remind me some images of the Japanese Metabolism; in particular, projects like the 1961's Helix City by Kisho Kurokawa. In this case the helix became some slightly more complex parabolas; multiplying for sine or cosine functions the displacement of the control points of each floor plate increases the whirling rise. The results are some quite articulated, still symmetrical, vertical vortex structures.

The code consists in a vertical extrusion of planar closed curves; each curve rotates a certain degree every level; the coordinates of the control points defining each curve are variable; some are also following a path determined by a sine function.
We are currently looking into some improvement of this -rather simple- algorhythm. More soon.

071220_Origami trusses

"In architecture and structural engineering, a truss is a structure comprising one or more triangular units constructed with straight slender members whose ends are connected at joints[...] The analysis of trusses often assumes that loads are applied to joints only and not at intermediate points along the members[...] Every member of the truss is then in pure compression or pure tension – shear, bending moment, and other more complex stresses are all practically zero." (wikipedia)

071120_Surface Tassellation


The surface is subdivided following UV coordinates; the logic of the script is, effectively, mapping the curvature of the surface; whereas the surface is flat and homogeneous the subdivision grid is large; where the surface curvature is steeper the subdivision gets further partitioned. It would be Interesting to see whether there is a correlation between scripting logic and structural logic. Undoubtedly the presence of the circles helps to stiffen the linear structural grid.

I apologize for the guilt delay in posting. Well, I've been spending some time practicing with Rhinoscript and trying to develop some meaningful results.
The script develops a surface tessellation exercise where components are distributed along the surface: this is a recursive script where the surface is subdivided according to its degree of curvature. In this manner smaller components are allocated where curvature is steeper, bigger ones where the curvature is rather flat.
More to come...

CROSS-BREEDING




Implementation of branching systems: the organizational potential of branching is used as a tool to unfold a prototypic canopy structure developed upon a series of parametrically controlled catenary truss surfaces.
The branching tree works as an abstract organizational machine where the parametrization of its very geometry allow to investigate several differentiated configurations exploring various degrees of porosity of the structure as well as multiple articulation of the internal partitions.The parametric setup allows the alteration of the geometrical arrangement of the tree updating, at the same time, the truss surfaces.

BRANCHING SYSTEM





OPEN SYSTEMS: BRANCHING STRUCTURE
Moving away from the homogeneous standardization homogeneous standardization of the Modern paradigm, this research, through the generative use of parametric tools, is seeking to investigate open systems as multi-performing, differentiated organizational systems.
In line with the experimentation on branching structures developed by Frei Otto, the research unfolds through a series of exercises aiming to open up a generative approach to parametric design: specificity is achieved through iterative differentiation, adaptation through redundancy, robustness through structural-geometric interdependency.
Understanding architectural design as a process of formation leads to the exploration of a pre-material state of a given systems: namely, the state prior to the crystallization into a specific design form is explored. In this way, open systems act as virtual machines prior to the actualization into a given design scenario.
Methodologically, different paths are followed in an attempt to open up potentials for inclusive performance:
Organizational logic> branching is explored as an organizational system. Different network topologies are analyzed and compared.
Geometrical logic> the geometrical logic of branching is created and developed through parametric tools: Digital project is employed to generate the geometrical structure; in addition differentiation is achieved by the instrumentalization of the defining principle: angle between branches, number of branches, length, displacement of the nodes in space…
An intricate matrix is then emerging from the proliferation of differentiated geometrical operation.
Structural logic> the structure and the stability of the various configurations is analyzed through finite element analysis software [FEA]. Thus running structural analysis necessitates specifying a range of parameters to set up likely structural scenarios.
Running structural tests on differentiated geometrical arrangements is possible to detect certain general behavioral patterns happening during the process of extracting precise data for structural analysis or fabrication.
The possibility to establish interdependent relationships between different system logics contributes to the redefinition of common fitness criteria: each system logic, instead of responding to a specific optimized scenario, informs each other towards a multi parametric performing whole. Geometrical arrangements, spatial affects, structural performance and organizational logic contribute to the formation of the system and its performance-based logic.

DREAMING DUBAI

This article has been published on the last issue of 2A magazine link
The dynamics that move the organization of the contemporary city continuously escape the remits of total comprehension and interpretation: hence the urban experience is characterized by its mutable and contradictory nature in which the market forces determine change and metamorphoses. These mutations simultaneously deeply modify both the complex dynamics of spatial and temporal usage within the contemporary city.
However, it could be argued that society also assists this relatively new phenomenon of transformation of the city due to necessities caused by deep economical changes. This is the case currently in Dubai. According to geological forecasts, in a relatively short period of time, the oil reserves will expire in the area of the Persian Gulf. In order to avoid a terrific economical crisis, a total reconfiguration of the city based on incentives to the tertiary 'invisible' sector has been choreographed. Services such as financial institutions, scientific research but mainly hotels and avant-garde architectural design all aid the transformation of Dubai into one of the most luxurious touristic places worldwide.
Once again, thus, the touristic sector represents that extraordinary instrument of urban transformation triggering changes of the historical as well as geographical profile of a place altering its character to better fit the expectations of an exotic leisure experience.
In the past 100 years, a phase of exponential development coincided with the advent of the modern mass society, tourism, which represents nowadays the world’s largest industry with a turnover of over 4 trillion, it confirms itself as the inexhaustible engine behind the process of redefinition and re-territorialisation of the contemporary urban reality.
Nevertheless, the rise of the touristic phenomenon lies in the deep shift occurred in western society in the last two centuries. In fact, the industrial society first and the post-industrial society, then, thanks to the increased productivity, have permitted a tendential decrease of the working hours: the working hours dropped, in certain cases, to less than 40 per week as well as it has been shortening the working period before pension.
This trend has permitted the progressive rescue of increasing quantity of free time promoting, within the capitalistic and late-capitalistic society, the development of leisure or entertainment intended as recreation, distraction from habitual preoccupations, pleasure, wellness.
Thus, such a tendency has clearly reflected, in the hierarchy of values, the placement of resources and in the time employed, the way the leisure has appeared to be a growing preoccupation in our society determining ultimately our welfare, our “quality of life”.
The organization of the free time is sub sequentially becoming more and more relevant and tends to characterize our life styles: the leisure, in effect, is taking the shape of several different activities such as sports, natural and recreational occupations as well as, most importantly, the discovery of the world.
In such context, therefore, tourism assumes features of a particular kind of leisure aiming to reshape the organization of free time within the global holiday resort.
The spread of tourism is pervasive and it doesn’t preclude any geographical boundary: the minimum common denominator of the contemporary journey experience is the exotic nature of a give destination in the endeavor of re-enchanting the world through its exploitation.
The repercussions of this on the organization of the contemporary city and its experience express themselves in various shapes and forms reflecting a new kind of hedonistic urban design.
Dubai, in this sense, represents the most advance experiment of contemporary urban marketing, strategizing its skyline in the attempt to invent a brand new exotic identity to attract visitors and capitals.
Nowadays it's only the beginning of this change; it seems to be destined to transform Dubai into a Wonderland: For example it is planned that three out of the Seven Wonders of the World will be constructed. Specifically, the Cheop's pyramid, the hanging gardens of Babylon, the Lighthouse of Alexandria. In addition Pisa's Tower, the Eiffel Tower and the Great Wall of China, will be sharply reproduced thanks to the employment of petrol-dollars.Beyond the debatable and, at the same time, colossal operations of urbanistic cut and paste which are radically reshaping Dubai, what makes this extraordinary open-air laboratory interesting is the gap determined by this experience in relation to the planning of the contemporary post modern city. The Post modern was, in fact, primarily an expression of a fundamental trend of the contemporary living linked with the general cultural environment, its lifestyles rather than fully reflecting itself into the shape of the city and its architectures.
Dubai represents the last evolutionary phase of the urban contemporary experience within which the desire, already to some extent, the heart of the urban organization in other contexts, becomes the only organizational criteria through which the right to plan dreamy urban scenarios totally overlap the real city. The fine boundary line between dreamed city and real city is literally translated into the articulation of the cityscape.Dubai, conceived and designed as a new luxurious Mecca, must reflect an ideal timeless beauty in which an a-critical collage composes the skyline. Precisely in line with the post modern urban experience and, moreover, formally born from that linguistic universe, Dubai represents, an urban ready-made in which a massive insertion of economical capitals together with the employment of the most advanced technologies and infrastructures makes possible the reification of a utopian urban condition. At the same time, its' effect is hyper-real and produces a temporal suspension in which the past is actualized within an eternal present. The Great Wall of China and the high-tech skyscrapers, the sky dome and an ancient Medina precisely reproduced, sit together within the city, which is becoming a self-simulacra.If the post modern city was posing itself in a dialectic relationship with the historical city, mimicking on one hand the architectural languages but, moreover, deeply changing the experiential aspects of the metropolitan life; Dubai represents the trait d'union between the post modern mindscape and the post modern cityscape. The shapes of the city, in fact, compose an urbanite bricolage in which the economical forces and the logic of profit originate a fragmented and contingent planning, fulfilling an oneiric view of the city and its parts. Nevertheless the urban planning, ultimately, is nothing but the reflection of a diffused hedonism, a mass individualism that is organizing the city through the right to the experience of pleasure.This is a sort of dictation of the desire in which what belongs to a utopian vision of the city and its wonders gains the right to be artificially realized. This is due to the employment of technology which is the medium in the service of "caprice": a sky slope in the desert, the tallest skyscraper of the world (800 meters), artificial islands forming palm trees-like archipelagos rather than world-like archipelagos with luxurious houses designed "in style" according to the continent they belong to. Dubai is there to satisfy the last fantasies within the city, it's the residual swatch of what could have already been but the technique were unable to realize; today even that taboo has gone.
