summary	Il n'est pas inéluctable d'utiliser, dans les écoles d'architecture et pour l'apprentissage de la conception, les outils logiciels qu'exploitent les architectes en phase de production. On exposera en quoi ces systèmes lourds et efficaces dans la fabrication des pièces écrites et graphiques en fin de projet, se révèlent inadaptés en phase d'apprentissage et de pré-conception. L'alternative ici proposée consiste à considérer un étudiant comme un acteur qui décide, dans un environnement multiple et changeant de modules logiciels, d'appeler tel ou tel élément propre à stimuler son imagination ou aider sa réflexion, dans la phase où il se trouve, dans le mode de représentation qu'il choisit. Cet environnement est considéré comme un dispositif. Quelques exemples existants de ces modules logiciels sont brièvement présentés, comme incitation à continuer d'explorer cette voie. La conclusion expose la difficulté de l'entreprise, mais insiste sur les enjeux qui y sont attachés.

summary	L'histoire montre la possibilité des deux voies de développement de l'homme : l'une naturelle, se basant sur les techniques de perfectionnement des sens et de l'esprit, et l'autre artificielle, qui s'appuie sur la fabrication des prothèses technologiques. Mais il semble que la société moderne ait déjà omis pour toujours la première voie : au réseau télépathique, nous avons privilégié le réseau télématique. Il est difficile d'évaluer les conséquences sociales et psychologiques d'un tel choix. Néanmoins, la prudence nous oblige à garder notre autonomie de la technologie. Alors, il faut la maîtriser au fond, et surtout former la génération future de façon non seulement pratique mais aussi philosophique et critique par rapport à elle. Seule l'imagination peut surpasser les prouesses technologiques. Comme le dit Umberto Ecco «même à défaut de génie, l?imagination est toujours créatrice .

title	Automatic generation and fabrication of designs
source	Automation in Construction 11 (3) (2002) pp. 291-302
summary	A framework for the generation and fabrication of architectural massing designs is presented. The framework consists of a computer program, which generates designs based on shape grammars, and rapid prototyping technologies that produce physical models of generated designs. The goal is to illustrate how geometrically complex designs, difficult to produce by hand, can be generated based on a few basic shapes and rules. The software developed uses Java, Open Inventor and cutting-edge 3D graphics technology. The extension of the proposed framework to one using the World Wide Web is briefly discussed.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	Digital Design - Research and Practice
source	Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1 / Tainan (Taiwan) 13–15 October 2003, 464 p.
summary	The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title	Prêt-à-Construire – An Educational Inquiry into Computer Aided Fabrication
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 162-165
summary	This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

title	Design from Known to New -Issues of Generative Architecture under Digital Environment
source	International Conference on Generative Art
summary	Given the power of digital design media, architects are confronting a new territory of architectural morphology. This paper attempts to explore the issues of generative architecture under digital environment. It is concerned with architectural precedents, their morphological attributes, and morphological analysis as the point of departure for generating new designs. Three design experiments are employed for the exploration. The first experiment addresses the issue of a single building. The second experiment focuses on the problem of urban architecture. The third design experiment places emphasis on the issue of urban landform. In addition to the exciting novel forms and spaces generated from the afore-mentioned design experiments, a number of critical issues on generative architecture are raised and discussed in the paper. Among them are: (1) the concept and logic underlying the methodology of the design experiments; (2) the formulation of the generative design systems utilizing the existing morphological structures; (3) the employment of the digital design media (e.g. image processing, 3D abstraction and extrusion) for various purposes during the process of analysis and generation.

title	A generative design system based on evolutionary and mathematical functions
source	International Conference on Generative Art
summary	Previous work by Professor John Frazer on Evolutionary Architecture provides a basis for the development of a system evolving architectural envelopes in a generic and abstract manner. Recent research by the authors has focused on the implementation of a virtual environment for the automatic generation and exploration of complex forms and architectural envelopes based on solid modelling techniques and the integration of evolutionary algorithms, enhanced computational and mathematical models. Abstract data types are introduced for genotypes in a genetic algorithm order to develop complex models using generative and evolutionary computing techniques. Multi-objective optimisation techniques are employed for defining the fitness function in the evaluation process.

title	Pseudo-urban automatic pattern generation
source	International Conference on Generative Art
summary	This research task aims to experiment automatic generative methods able to produce architectural and urban 3D-models. At this time, some interesting applicative results, rising from pseudo-random and l-system formalisms, came to generate complex and rather realistic immersive environments. Next step could be achieved by mixing those techniques to emerging calculus, dealing whith topographic or environmental constraints. As a matter of fact, future developments will aim to contribute to archeological or historical restitution, quickly providing credible 3D environments in a given historical context.

title	Shapes, Numbers, Perception: Aspects and Dimensions of the Design-Performance Space
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	The design-performance space denotes a virtual space that can be constructed based on discretized design variables and performance indicators. For an n-dimensional design-performance space, n = d + p,whereby d = the number of discrete design variables, and p = the number of discrete performance indicators. Once constructed, this space can be visualized and used by the designer to explore the relationship between design variables and corresponding performance attributes. We present, for the building design domain, an approach to generation and exploration of the design-performance space. In this approach, an initial design is used to generate a set of alternative designs that collectively constitutethe design space. One way of doing this relies on the "scalarization" of design variables. The scalarization leads to the representation of a building as a point in a d-dimensional design space. Each coordinate ofsuch a space accommodates a salient (semantic or geometric) design variable. Subsequently, the entire corpus of design alternatives is subjected to performance modeling. Based on the modeling results, an ndimensionaldesign-performance space is constructed. We specifically address the potential for and limitations of describing building geometry in terms of a continuous scalar dimension of the design space. We introduce the concept of "Relative Compactness", which is derived by comparing the volume tosurface area ratio of a shape to that of a (compact) reference shape with the same volume. We present the results of an empirical study, which shows a significant correlation between the numeric values of relativecompactness and the subjective evaluation of the compactness of architectural shapes.

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	Cork Re-Wall. Computational Methods of Automatic Generation and Digital Fabrication of Cork Partition Walls for Building Renovation
source	SIGRADI 2015 [Proceedings of the 19th Conference of the Iberoamerican Society of Digital Graphics - vol. 1 - ISBN: 978-85-8039-135-0] Florianópolis, SC, Brasil 23-27 November 2015, pp. 86-93.
summary	Developments in computational design methods and their integration with digital fabrication processes are ushering a customized fabrication paradigm. This paradigm is particularly suited to renovation of old buildings built with traditional construction techniques, a diversified corpus in which interventions are surgical and unique, and where partition walls play the central role. Insulation Cork Board and OSB, natural and renewable materials, can have an important role in a material system that responds to this context. Cork re-Wall is a parametrically modelled construction system and a file-to-factory digital process to generate high quality custom solutions to respond to diverse renovation design challenges.

title	Generative geometric design and boundary solid grammars
source	Carnegie Mellon University, Department of Architecture
summary	This thesis explores the automatic generation of solid models based on a grammatical paradigm. It introduces a formalism, boundary solid grammars, for this purpose. In this formalism, a set of geometric rules is applied to an initial solid model to generate a language or family of solids. A rule may match on a portion of the boundary of a solid, and then modify the solid or add new solids. Genesis is presented as an implementation of the formalism. A number of grammars have been constructed to demonstrate the concepts and usefulness of the formalism. These grammars generate simple geometric forms including snodakes, recursive octahedra, “fractal” mountains, and spirals. Another grammar generates stereo lithography support structures. Queen Anne houses have been characterized with a more extensive grammar. Grammars are also being developed to generate housings for small computers and structural designs for high rise buildings. The thesis introduces the unary shape operations and a new paradigm for solid modeling, The unary shape operations take models that may have self-intersections, interpret the models consid- ering the given geometry and face orientations, and produce valid models. Local operations, the unary shape operations, and Boolean operations are used together within a valid modeling scheme. The thesis introduces a new boundary representation for manifold and nonmanifold solids, the generalized split-edge representation. It describes generalized Euler operations which manipulate the topology of the nonmanifold representation. Finally, the thesis presents a form of the Euler- Poincare equation that characterizes the relationship between elements of nonmanifold surfaces of solids.

summary	Information extracted from aerial photographs is widely used in urban planning and design. An effective method for detecting buildings in aerial photographs is to use deep learning for understanding the current state of a target region. However, the building mask images used to train the deep learning model are manually generated in many cases. To solve this challenge, a method has been proposed for automatically generating mask images by using virtual reality 3D models for deep learning. Because normal virtual models do not have the realism of a photograph, it is difficult to obtain highly accurate detection results in the real world even if the images are used for deep learning training. Therefore, the objective of this research is to propose a method for automatically generating building mask images by using 3D models with textured aerial photographs for deep learning. The model trained on datasets generated by the proposed method could detect buildings in aerial photographs with an accuracy of IoU = 0.622. Work left for the future includes changing the size and type of mask images, training the model, and evaluating the accuracy of the trained model.

summary	The integration of industrial robots in the creative art industry has increased in recent years. Implementing both brick stacking robotic fabrication, following a curved wall, and generating an image viewed from a single point, by rotating the bricks around their centres, has yet to be studied. The goal of this research is to develop a functional, parametric working model and a workflow that ensure easy manipulation and control of the desired outcome via parameters. This paper shows a workflow for the automatic generation of anamorphic structures on a curved wall by utilizing modular brick-like elements. As a result, a code for the robot controller and the position of the structure during fabrication are provided.
