summary	The dynamics of a physics-based algorithm which acquires its complex organization through a number of localised interactions applied over a prescribed network can be described as a self-organised system. This in turn has the capacity to define explicit form and space based upon behavioural computational processes with an embedded structural logic. This paper discusses the way in which physics based algorithms can be used to inform the organisation of a compressional structure in a case study. Its structure is based on Hooke’s law of elasticity; which establishes a three dimensional catenary logic through a number of localised interactions applied over an entire network. This is applied to a project with specific constraints to site, boundary conditions and maximising solar gain whilst maintaining structural rigidity. The methodological approach describes the design to assembly process in which the project has been developed. This includes the applied generative design tools in order to establish the self-organised logic, the form finding process, the techniques of design documentation, the fabrication process and the logistics of construction and assembly.

summary	This paper investigates the integration of Building Performance Simulation (BPS) and optimization tools to provide high performance solutions. An office room in Cairo, Egypt was chosen as a base testing case, where a Genetic Algorithm (GA) was used for optimizing the annual daylighting performance of two parametrically modeled daylighting systems. In the first case, a combination of a redirecting system (light shelf) and shading system (solar screen) was studied. While in the second, a free-form “gills surface” was also optimized to provide acceptable daylighting performance. Results highlight the promising future of using computational techniques along with simulation tools, and provide a methodology for integrating optimization and performance simulation techniques at early design stages.

summary	While parametrics and form-finding techniques focus on design as an idea of “search,” it is inevitable to wonder if the field is becoming stagnated, converging on similar “solutions” in an ever-shrinking design search space.Initiatives like Minecraft, coming from video game design, reopen the creative desires of players by providing a rigorous algorithmic set of rules and a fully open world coupling algorithmic design and intuition. This is what J.C.R. Licklider would call “man-computer symbiosis”(Licklider 1960).This paper presents how game mechanics suggest a radically different ethos for computational design thinking. It presents the Bloom project, commissioned for the London Olympics in 2012, which combines the use of industrially produced identical components with game mechanics. This project breaks the idea of serialized outcomes and suggests that within the search space of possible formations, there are unforeseeable assemblies and creative outcomes.The Bloom project has become a new research unit at UCL Bartlett, coupling notions of digital modular materials and crowd-farming for assembly, which positions gaming as a design heuristics to open the field of architectural design.

summary	This paper proposes a computational form-finding method for integrating parametric origami design and acoustic engineering to find the best geometric form of a concert hall. The paper describes an application of this method to a concert hall design project in Japan. The method consists of three interactive subprograms: a parametric origami program, an acoustic simulation program, and an optimization program. The advantages of the proposed method are as follows. First, it is easy to visualize engineering results obtained from the acoustic simulation program. Second, it can deal with acoustic parameters as one of the primary design materials as well as origami parameters and design intentions. Third, it provides a final optimized geometric form satisfying both architectural design and acoustic conditions. The method is valuable for generating new possibilities of architectural form by shifting from a traditional form-making process to a form-finding process.

title	Frameworks for Computational Design of Textile Micro-Architectures and Material Behavior in Forming Complex Force-Active Structures
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 281-292

summary	Material behavior can be defined as the confluence of associative rules, contextual pressures and constraints of materialization. In more general terms, it can be parameterized as topologies, forces and materiality. Forming behavior means resolving the intricate matrix of deterministic and indeterministic factors that comprise and interrelate each subset of these material- nherent conditions. This requires a concise design framework which accumulates the confluent behavior through successive and cyclical exchange of multiple design modes, rather than through a single design environment or set of prescribed procedures. This paper unfolds a sequencing of individual methods as part of a larger design framework, described through the development of a series of complex hybrid- structure material morphologies. The “hybrid” nature reflects the integration of multiple force-active structural concepts within a single continuous material system, devising both self-organized yet highly articulated spatial conditions. This leads primarily to the development of what is termed a “textile hybrid” system: an equilibrium state of tensile surfaces and bending-active meshes. The research described in this paper looks to expose the structure of the textile as an indeterministic design parameter, where its architecture can be manipulated as means for exploring and differentiating behavior. This is done through experimentation with weft-knitting technologies, in which the variability of individual knit logics is instrumentalized for simultaneously articulating and structuring form. Such relationships are shown through an installation constructed at the ggggallery in Copenhagen, Denmark.

summary	Design computation based on data flow graph diagramming is a well-established technique. The intention of DesignScript is to recognise this type of data flow modeling as a form of ‘associative’ programming and to combine this with the more conventional ‘imperative’ form of programming into a single unified computational design application. The use of this application is intended to range from very simple graph based exploratory ‘proto-programming’ as used by novice end-user programmers to multi-disciplinary design optimisation as used by more experienced computational designers.

summary	Visual rules are powerful in loosely capturing the impact of material behavior on form in designer’s hands-on experimentation. They present a first step to translate the causal relations between material and form to computation without sacrificing the uncertainties in the designer’s interaction with the materials. This study investigates how to model the relation between material and form with visual rules so that the model embodies some of the phenomenological aspects of reality, rather than merely reproducing it.

title	Design Constraint Systems - A Generative Approach to Architecture
source	International Journal of Architectural Computing vol. 11 - no. 1, 37-63
summary	Generative Architectural Design permits the automatic (or semiautomatic) generation of architectural objects for a wide range of applications, from archaeological research and reconstruction to digital sketching. In this paper the authors introduce design constraint systems (DCS), their approach to the generation of architectural design with the help of a simple example: The development of the necessary formalisms to generate a family of architectural designs, i.e. simple houses and pagodas. After explaining the formal system the authors introduce an approach for the generation of complex form based on the application of transformations and distortions.Architecture is bound by the constraints of physical reality: Gravitation and the properties of the used materials define the limits in which architectural design is possible. With the recent development of new materials and construction methods however, the ways in which form and physics go together get more complicated. As a result, the shapes of architecture gain more liberty, and more and more complex shapes and structures become possible.While these advances allow for new ways of architectural expression, they also make the design process much more challenging. For this reason new tools are necessary for making this complexity manageable for the architect and enable her to play and experiment with the new possibilities of complex shapes and structures. Design constraint systems can be used as tool for experimentation with complex form. Therefore, the authors dedicate the final part of this paper to a concise delineation of an approach for the generation of complex and irregular shapes and structures. While the examples used are simple, they give an idea of the generality of design constraint systems: By using a two-component approach to the generation of designs (the first component describes the abstract structure of the modelled objects while the second component interprets the structure and generates the actual geometric forms) and allowing the user to adjust both components freely, it can be adapted to all kind of different architectural styles, from historical to contemporary architecture.

title	Aerodynamic Performance Driven Form-Generation for Skyscraper Design

summary	I have conducted a study to explore aerodynamic performance as a driver for skyscraper design, utilizing up-to-date parametric design and computational fluid dynamics (CFD) technologies readily available to architects. Previous scientific research has suggested strategies in modifying the form of skyscrapers for the purpose of improving their aerodynamic performance. I have incorporated six of such strategies into parametric design tool to produce a matrix of 60 prototypes. These prototypes are subjected to qualitative and quantitatively evaluation iterations to yield the most optimized design, with considerations given primarily to aerodynamic performance, and secondarily to structural robustness, program potential, and image attractiveness. The selected design option is further developed into a skyscraper concept. A multi-staged aerodynamic performance-driven design process is the most important result of the study. In addition, two valuable insights have been obtained: first, to inject a new inspiration into the design of skyscrapers, I have implemented the MultiDisciplinary Optimization (MDO) methodology from the aerospace industry. Second, I am able to support form-generation parametric design by quantitative evaluation process.

title	The Resolution of Architecture in the Digital Age
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 347-357.
summary	The resolution of architecture is a measure of the spatial density of information inherent in a building. This paper demonstrates how the confluence of advances in computational design and additive manufacturing has recently led to a paradigm shift in potential architectural resolution. Buildings can now be designed and fabricated with elements at the threshold of human perception. This resolution can be used to replicate existing architectural styles ever more efficiently and accurately. Yet as with the introduction of other new technologies, architects must now explore the latent potentials and determine what kind of new architectures become conceivable. Specifically, what architectures can adequately express this enormous resolution and the unlimited geometric complexity within reach? With the project Digital Grotesque, we present the first human-scale, enclosed structure that truly exploits these opportunities. Algorithms are used to articulate and orchestrate the geometry from the macro scale down to 1mm small details. The structure is enriched with local information at a previously unseen resolution. A unique language of form is developed that transcends rationality and celebrates spatial expression: a digital exuberance.

title	Multiplying Architectural Layouts and 3D Forms: Interplay of Necessity and Contingency in Architectural Modeling
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 338-346.
summary	Since 1960s there were many models for architectural layout planning which formulated design activities as problem-solving. On the other hand, various form-finding models had emerged after 1980s. The former seeks the necessity of architectural modeling as an objective science, while the latter encourages the contingent characters of individual modeling. This paper proposes a method of integrating the two families of models. A commutation channel is defined thus every member in one family can work with any member in the other. Therefore the models of architectural layouts can “multiple” the models of 3D forms, which leads to rich variety of architectural structures and forms. The method is implemented and tested in Java.

summary	In architecture use of generative computation suggests a possibility of rethinking the form finding process. In order to generate form, one method could be predefining first the production technique and constraining the form by the rules of it. In this study crochet-knitting technique is chosen as a production technique. To explore various forms developed through this technique; a computational model, which the behavior of crochet-knitted surface is embedded into, is developed. This paper explains the process of decoding the behavior of a crochet-knitted surface for a computational model in order to extract the crochet-knitting patterns of complex geometrical surfaces.

summary	The paper concerns the potential of sensors as architectural design tools in different spatial and temporal scales. In particular, the focus is on how sensors are able to operate in a constantly changing environment, and how sensors might nurture an intuition of otherwise non perceivable aspects of performance within architecture.The study discus two set-ups. Firstly; an onsite sensor reading of changing performance between a refurbished and a classic Arabic house; the study is in large spatial and temporal scale. Secondly; a model design setup where the performance of the same Arabic house typology is tested in small spatial and small temporal scale. The study shows how large scale architecture can be investigated through the use of sensor chaining and how simple sensors can be implemented in a design task in order to give insight to certain aspects of performance. The paper concludes with a discussion on a more general sensor strategy for changing environments and design setups.

summary	In this study, we propose a novel computational system called WoodWeaver for fabricating curved surfaces from conventional materials without using moulds. We use a cutting-based material bending method called Dukta. Our system enables a user to design a single free-form curved surface and to fabricate it based on the bending deformation characteristics of the material. The system also indicates an invalid shape; that is, one that will break upon bending deformation. The user can then design a valid shape with this information. We also develop an optimal Dukta pattern that is the smallest-sized gap pattern necessary to represent a user-designed shape. Given a valid shape, the system generates the optimal pattern and a machine cuts four modules with this pattern. Finally, the user assembles these modules to obtain the desired shape.

summary	Architectural discourse has recently suggested a new material practice derived from advances in the field of synthetic biology. As biological organisms can now be designed and engineered for specific purposes, it is expected that, in the near future, it will be possible to program even more complex biologically based systems. One potential application is to literally grow buildings by programming cellular organisms to fabricate and deposit material into architecturally relevant patterns. Our current design methods do not anticipate the potentially challenging material practice involved in a biologically engineered architecture, where there is a loose and emergent relationship between design and material articulation. To tackle this conflict, we developed SynthMorph, a form-finding computational tool based on basic biological morphogenetic principles. A reflection is offered on its use, discussing the effect of multicellular morphogenesis on the production of shape. We conclude that such a strategy is an adaptive design method in two ways: (a) the mechanics of design using morphological constraints involve a practice of dynamic and continuous negotiation between a design intent and material emergence, and (b) the proposed design strategy hints at the production of a biologically produced architecture, which would potentially behave as an adaptive organism.

summary	The promise of robotic fabrication as an enabler for mass-customization in Architecture has been hindered by the intricate workflow required to go from parametric modelling to CNC fabrication. The lack of integration between highly-specialized proprietary software, normally required to operate the machines, and most of the design tools constitutes a major limitation. One way to tackle this constraint is by developing simple tools that directly link parametric modelling to robotic coding. Accordingly, “Fisac Variations” develops an uninterrupted digital workflow from form-generation to robotic fabrication. This innovative approach to Computer Aided Design and Manufacturing was tested by studying and reengineering a specific historic construction system -Miguel Fisac’s Bones System was used as a case study- and by enabling it to address problems of contemporary architectural agenda such as flexibility, variability and mass-customization. The proposed workflow threads form-finding, structural analysis, geometric definition, CNC code generation and digital fabrication within the same open-source computational environment. In this way, this innovative procedure aims to increase design freedom while ensuring fabrication feasibility. This paper describes background research, concept, form-finding, construction process, methodology, results and conclusions.

summary	In the 19th century it was common to use graphical methods for study the relationship between form and force. The central element of all drawing methods for representing the inner flow of forces was the investigation of the dependence of equilibrium and force polygons, as well as their representation in two geometrically dependent diagrams with different units. This research is part of an on going project to extend the methods of ‘graphical statics’ of Carl Culmann (1866) to the third dimension in order to overcome some of the 2D-limitations of this approach. It is focused on the construction of resulting force within 3D and the utilization within discrete space frames (tetrahedrons) in equilibrium. The objective of the EGS is to focus on constructing in contrast to calculating. That means that the logic of the inner force flow leads to a process-oriented and visible approach of design, which gets computationally accessible. With the use of digital tools and increasing importance of performative methods of form-finding a renewed interest in these vector-based geometric methods of construction of force flow has occurred. This may be will give the possibility to get an alternative to the common form finding methods by relaxation processes and analysis by FEM.

title	Progeny: A Grasshopper Plug-in that Augments Cellular Automata Algorithms for 3D Form Explorations
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 377-391
summary	Cellular automata (CA) is a well-known computation method introduced by John von Neumann and Stanislaw Ulam in the 1940s. Since then, it has been studied in various fields such as computer science, biology, physics, chemistry, and art. The Classic CA algorithm is a calculation of a grid of cells' binary states based on neighboring cells and a set of rules. With the variation of these parameters, the CA algorithm has evolved into alternative versions such as 3D CA, Multiple neighborhood CA, Multiple rules CA, and Stochastic CA (Url-1). As a rule-based generative algorithm, CA has been used as a bottom-up design approach in the architectural design process in the search for form (Frazer,1995; Dinçer et al., 2014), in simulating the displacement of individuals in space, and in revealing complex relations at the urban scale (Güzelci, 2013). There are implementations of CA tools in 3D design software for designers as additional scripts or plug-ins. However, these often have limited ability to create customized CA algorithms by the designer. This study aims to create a customizable framework for 3D CA algorithms to be used in 3D form explorations by designers. Grasshopper3D, which is a visual scripting environment in Rhinoceros 3D, is used to implement the framework. The main difference between this work and the current Grasshopper3D plug-ins for CA simulation is the customizability and the real-time control of the framework. The parameters that allow the CA algorithm to be customized are; the initial state of the 3D grid, neighborhood conditions, cell states and rules. CA algorithms are created for each customizable parameter using the framework. Those algorithms are evaluated based on the ability to generate form. A voxel-based approach is used to generate geometry from the points created by the 3D cellular automata. In future, forms generated using this framework can be used as a form generating tool for digital environments.

summary	This paper presents the design, control system, and elastic behavior of ELAbot: a robotic bending active textile hybrid (BATH) structure that can self-form and transform. In BATH structures, equilibrium emerges from interaction between tensile (form active) and elastically bent (bending active) elements (Ahlquist and Menges 2013; Lienhard et al. 2012). The integration of a BATH structure with a robotic actuation system that controls global deformations enables the structure to self-deploy and achieve multiple three-dimensional states. Continuous elastic material actuation is embedded within an adaptive cyber-physical network, creating a novel robotic architectural system capable of behaving autonomously. State-of-the-art BATH research demonstrates their structural efficiency, aesthetic qualities, and potential for use in innovative architectural structures (Suzuki and Knippers 2018). Due to the lack of appropriate motor-control strategies that exert dynamic loading deformations safely over time, research in this field has focused predominantly on static structures. Given the complexity of controlling the material behavior of nonlinear kinetic elastic systems at an architectural scale, this research focuses on the development of a cyber-physical design framework where physical elastic behavior is integrated into a computational design process, allowing the control of large deformations. This enables the system to respond to conditions that could be difficult to predict in advance and to adapt to multiple circumstances. Within this framework, control values are computed through continuous negotiation between exteroceptive and interoceptive information, and user/designer interaction.
