title	Resolving some Ambiguities in Real-time Design Drawing Recognition by means of a Decision Tree for Agents
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 311-320
summary	In this paper, we present a theoretical study on automated understanding of the design drawing. This can lead to design support through the natural interface of sketching. In earlier work, 24 plan-based conventions of depiction have been identified, such as grid, zone, axial system, contour, and element vocabulary. These are termed graphic units. Graphic units form a good basis for recognition of drawings as they combine shape with meaning. We present some of the theoretical questions that have to be resolved before an implementation can be made. The contribution of this paper is: (i) identification of domain knowledge which is necessary for recognition; (ii) outlining combined strategy of multi-agent systems and online recognition; (iii) functional structure for agents and their organisation to converge on sketch recognition.

summary	Paradoxically, one of the most difficult but enjoyable things we do is to imagine. To open the eyes of our mind and see what no one else can see. We see images of things that are yet to be and through the same skill we devise ways in which to make them happen. We design the future in the form of environments, graphics, products, films, and a growing range of new media. Our ability to develop a vision and to visualize it is a gift that we are called to cultivate and put to good use. We have been privileged with a great responsibility. In the process of developing a vision and communicating that vision to others, we “visualize”. Visualization can be a very private experience in which we are alone with mental images that help us shape our vision. In other instances visualization can be a component of mass communication. Visualization can be a means or can be an end. It can be a small architectural sketch on a paper napkin or a mega-graphic covering a high-rise building, an airplane or a ship. In every case, the relationship between vision and visualization is a mutually supportive articulation of what our eyes and our minds can see. Our vision of the role of computers in the art and science of visualization is in constant development. Computer visualization can support an intimate dialog between a designer and his/her vision. It can translate and communicate that vision to a larger audience and in the hands of a new-media artist it can actually constitute his/her vision. The 9th Annual Conference of SIGraDI (Ibero American Society for Computer Graphics) will explore our collective vision on the future of digital visualization and digital media in Environmental Design, Product Design, Graphic Design, Cinematography, New Media, and Art. Authors are invited to share their research work with a focus on how it contributes to shape a collective understanding of the past, awareness of the present, and vision of the future in our multiple disciplines.

title	Urban Grammars: Towards Flexible Urban Design
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 491-500

summary	Traditional urban plans have definitive design systems, without the flexibility required to deal with the complexity and change that characterise contemporary urban societies. To provide urban plans with increased flexibility, it is proposed a design methodology capable of producing various design solutions instead of a specific definitive design. The methodology uses shape grammars as a process for generating urban design. In this approach, design becomes a system of solutions rather than a specific one. Through the analyses of a group of urban plans, a design methodology was sketched in which rules are used to enable more flexibility. These plans where chosen for their perceived qualities in terms of language, planning efficiency, and latent flexibility. As a result, a four-phased methodology was identified and thus, proposed for designing urban plans. This methodology was then combined with shape grammars and tested in a design studio setting. Students were asked to use the methodology and shape grammars as auxiliary instruments in the design of a flexible plan for a new town. In the following year, to simulate real-world conditions and oblige students to consider urban ordering and scale, work was structured differently. First, students were asked to develop a rule-based urban plan as in the previous year. Second, they were asked to conceive a detail plan for a sector of an urban plan defined by another group of students following its rules. The plans were then analysed with the goal of refining the methodology. Results show that shape grammars produce urban plans with non-definitive formal solutions, while keeping a consistent spatial language. They also provide plans with explicit and implicit flexibility, thereby giving future designers a wider degree of freedom. Finally, they provide students with a concrete methodology for approaching urban design and foster the development of additional designing skills.

title	Fabricating Ceramic Covers
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 269-276

summary	This paper describes a studio experiment developed with the aim of exploring the design and fabrication of innovative roof systems based on ceramic tiles using digital technologies. History is rich in examples of the use of ceramic roof tiles since the ancient world. Today’s systems derive from such ancient systems and fall into several basic categories depending on the form of the tiles and how they interlock. These systems present acceptable functional performances due to centuries of refinement, but as they have suffered little formal evolution in recent centuries, to respond to modern needs they require complex layering and assemblies. Recent technological evolution has emphasized the optimization of the tile production process in terms of time saving and cost reduction, and the improvement of product quality in terms of material homogeneity and durability. Little attention has been paid to the tile form and the roof system as a whole, including the assembly process. As a result, despite the variety and performance of existing designs, they are often perceived as outdated by architects who refuse to use them following a stylistic trend in architectural design towards primary forms and flat roofs. The challenge of the experiment was to take advantage of digital design and fabrication technology to conceive systems with improved performance and contemporary designs. The hope was that this could lead architects to consider integrating roof tiles systems in their architectural proposals. Results yielded five different roof systems. These systems are innovative from a formal viewpoint both at the tile and roof level. In addition, they are easy to assemble and possess better thermal and water-proofing performance. Digital technologies were determinant to enable students to design the complex shape of the tiles, to manipulate them into assemblies, and to assess the shape of the roofs, as well as their thermal and structural performance in some cases.

title	Cyclopean Cannibalism. A method for recycling rubble

summary	Each year, the United States discards 375 million tons of concrete construction debris to landfills (U.S. EPA 2016), but this is a new paradigm. Past civilizations cannibalized their constructions to produce new architectures (Hopkins 2005). This paper interrogates one cannibalistic methodology from the past known as cyclopean masonry in order to translate this valuable method into a contemporary digital procedure. The work contextualizes the techniques of this method and situates them into procedural recipes which can be applied in contemporary construction. A full-scale prototype is produced utilizing the described method; demolition debris is gathered, scanned, and processed through an algorithmic workflow. Each rubble unit is then minimally carved by a robotic arm and set to compose a new architecture from discarded rubble debris. The prototype merges ancient construction thinking with digital design and fabrication methodologies. It poses material cannibalism as a means of combating excessive construction waste generation.

title	Architecture and Biological Analogies
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 599-606
doi	https://doi.org/10.52842/conf.ecaade.2005.599
summary	The study described in this paper evolves within the larger context of a research aimed at inquiring into analogies between architecture and nature, and more specifically between architecture and biology. Biology is a recursive source of architectural inspiration due to the tight relationship between form and function, the natural balance of forces and the corresponding geometric solutions found in living beings. Roughly, one can classify historical analogies between architecture and biology into two main categories. The first tries to mimic biological forms and the second biological processes. The specific goal of the described study is to find how new technologies can redefine and support the process of constructing such analogies. It uses as a case study a tower project designed by the architect Manuel Gausa (ACTAR, Barcelona) called Tornado Tower because of its complex shape inspired in the frozen form of a tornado. Due to the geometric irregularities of the tower, Gausa’s team had difficulties in designing it, especially because solving the structural problems required constant redrawing. This paper describes the first part of the study which primary goal was to conceive a parametric program that encoded the overall shape of the Tornado Tower. The idea was to use the program to simplify the drawing process. This required a mathematical study of spirals and helices which are at the conceptual basis of the external structure and shape of the tower. However, the program encodes not only the shape of Gausa’s tower, but also the shapes of other buildings with conceptual similarities. Such class of shapes is very recurrent in nature with different scales and with different utilities. Therefore, one can argue that the program makes a mathematical connection between a given natural class of shapes and architecture. The second part of the study will be devoted to extending the program with a genetic algorithm with the goal of guiding the generation of solutions taking into account their structural fitness. This way, the analogy with genetic procedures will be emphasized by the study of the evolution of forms and its limits of feasibility. In summary, the bionic shape analogy is made by the generation of mimetic natural forms and a genetic process analogy starts with the parametric treatment of shape based on code manipulations. At the end the program will establish an analogy between architecture and biology both terms of form and process.

title	HYBRID MODELING: MANUAL AND DIGITAL MEDIA IN THE FIRST STEPS OF THE DESIGN PROCESS
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 819-827
doi	https://doi.org/10.52842/conf.ecaade.2005.819
summary	This paper proposes a new paradigm in computer-aided design: hybrid modeling. Considering, on one hand the traditional sketches and mock-ups, and digital techniques on the other, this paradigm fuses the two and proposes a new technique that uses the performance of the digital with the capacities of the analog without replacing or imitating one or the other. In the development of design computer solutions, it is important to know the user well. However, most researchers propose systems that do not consider how designers actually work. Furthermore, two principal elements must be considered in the design process: shape and space. These aspects need to be approached with convenient tools that are adapted to the designers. This new paradigm is presented through two new innovative techniques: the hybrid mock-up (for shape) and drafted virtual reality (for space). A review of the implications of this paradigm on the design process is presented. Not only are the techniques fast and easy to learn and execute, but the results demonstrate that the designers can express both their individuality and the idiosyncrasies of their personal representations; important elements that are difficult to achieve with conventional 3D modeling techniques, especially during the primary stages of the design process.

title	Creative Design Between Representation and Simulation
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 11-12
summary	Milestone figures of architecture all have their different views on what comes first, form or function. They also vary in their definitions of creativity. Apparently, creativity is very strongly related to ideas and how they can be generated. It is also correlated with the process of thinking and developing. Creative products, whether architectural or otherwise, and whether tangible or intangible, are originated from ‘good ideas’ (Elnokaly, Elseragy and Alsaadani, 2008). On one hand, not any idea, or any good idea, can be considered creative but, on the other hand, any creative result can be traced back to a good idea that initiated it in the beginning (Goldschmit and Tatsa, 2005). Creativity in literature, music and other forms of art is immeasurable and unbounded by constraints of physical reality. Musicians, painters and sculptors do not create within tight restrictions. They create what becomes their own mind’s intellectual property, and viewers or listeners are free to interpret these creations from whichever angle they choose. However, this is not the case with architects, whose creations and creative products are always bound with different physical constraints that may be related to the building location, social and cultural values related to the context, environmental performance and energy efficiency, and many more (Elnokaly, Elseragy and Alsaadani, 2008). Remarkably, over the last three decades computers have dominated in almost all areas of design, taking over the burden of repetitive tasks so that the designers and students can focus on the act of creation. Computer aided design has been used for a long time as a tool of drafting, however in this last decade this tool of representation is being replaced by simulation in different areas such as simulation of form, function and environment. Thus, the crafting of objects is moving towards the generation of forms and integrated systems through designer-authored computational processes. The emergence and adoption of computational technologies has significantly changed design and design education beyond the replacement of drawing boards with computers or pens and paper with computer-aided design (CAD) computer-aided engineering (CAE) applications. This paper highlights the influence of the evolving transformation from Computer Aided Design (CAD) to Computational Design (CD) and how this presents a profound shift in creative design thinking and education. Computational-based design and simulation represent new tools that encourage designers and artists to continue progression of novel modes of design thinking and creativity for the 21st century designers. Today computational design calls for new ideas that will transcend conventional boundaries and support creative insights through design and into design. However, it is still believed that in architecture education one should not replace the design process and creative thinking at early stages by software tools that shape both process and final product which may become a limitation for creative designs to adapt to the decisions and metaphors chosen by the simulation tool. This paper explores the development of Computer Aided Design (CAD) to Computational Design (CD) Tools and their impact on contemporary design education and creative design.

title	DEFINITION OF A METHOD OF LIMITS OF THE SIMPLIFICATION OF A HALL MODEL IN A CAD SYSTEM TO DIMINISH FALSIFICATION OF ACOUSTIC SIMULATION RESULTS
source	International Congress eCAADe 2005 (Education and research in Computer Aided Architectural Design in Europe), subject : “Digital Desing : the quest for new paradigms”, ISBN 0-9541183-2-4, pp. 695-704, Technical University of Lisbon, Portugal, 21-24 September 2005
summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi-EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary	The conceptual design at the beginning of the building construction process is essential for the success of a building project. Even if some CAD tools allow elaborating conceptual sketches, they rather focus on the shape of the building elements and not on their functionality. We introduce semantic roomobjects and roomlinks, by way of example to the CAD tool ArchiCAD. These extensions provide a basis for specifying the organisation and functionality of a building and free architects from being forced to directly produce detailed constructive sketches. Furthermore, we introduce consistency analyses of the conceptual sketch, based on an ontology containing conceptual relevant knowledge, specific to one class of buildings.

title	Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary	The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

doi	https://doi.org/10.52842/conf.caadria.2005.496
summary	By incorporating parametric surfaces and spline entities into the shape modeling computer systems, new design and production graphic tools have been created in the conceptual and poetic field of architecture; thus allowing an intuitive approach to the fast production of complex shapes with a minimum amount of data and specific knowledge. The analogous production systems (constrained by the material resources and constructive procedures present in the local existing technologies) are challenged by design and virtual simulation systems, suggesting new relationships between the architectural features and their representation: the creation of a symbolic and dynamic information space where the representation affects the identity of what is being represented. Taking into account this current challenge mentioned above, we have decided to work in the mixture, without reciprocal exclusions or substitutions, proposing some work alternatives to approach the issue under discussion in the Architecture Workshop.

title	Representational Thickness: a quantitative comparison between physical, CAVE and Panorama environments
source	International Journal of Architectural Computing vol. 3 - no. 1, 127-144
summary	This study compares aspects of spatial perception in a physical environment and its virtual representations in a CAVE and Panorama. To measure accuracy of spatial perception, users were asked to look at identical objects in the three environments and then locate them and identify their shape on scaled drawings. Results were then statistically compared for differences. In a discussion of the results, the paper addresses three hypothetical assertions – that depth perception in physical reality and its virtual representations in CAVE and Panorama are quantifiably different; that differences are attributable to prior contextual experience of the viewer; and that design professionals and laypeople have different perceptions of what they see in VR. In conclusion, the concept of 'representational thickness' is suggested by the results.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 684-688
summary	One of the architectural positions characterized by a visual singularity, it has been that of Zaha Hadid. It will be their particular contribution to the renovation of the architectural representation, through different graphic techniques, analogical and digital, and scale models. Hadid has created its own visual code in which the configuration of the shape and the representation are inseparable, standing out the generating role of the architecture on the part of the representation, beyond its instrumental role, with their peculiar paintings, drawings, scale models and their sophisticated renderings. By analyzing the graphic strategies in relation to the intentions or architectural contents along several proposals, it will conclude showing, through their special graphic style, their contribution to the innovation of the expression of the contemporary project.

title	Interpretation of Implicit Design Knowledge in Architectural Drawings Into Explicit Knowledge

doi	https://doi.org/10.52842/conf.caadria.2005.023
summary	This paper concerns a methodology in applying architectural design knowledge to the interpretation of design concepts from architectural drawings. We formalize the design knowledge such that knowledge plays a key role in the design interpretations that map between drawings and their design concepts. We consider this mapping, in general, as those linking between design decision space and design performance space, where design variables in both spaces are examined and categorized from the drawings and concepts. Examinations on drawings are performed based on qualitative shape analysis schemes and we apply feature-based shape analysis techniques to encapsulate those design characteristics in decision space. Interpretations of design concepts through shape characteristics are based on mostly two types of symmetries, namely cyclic and dihedral groups. We use CommonLISP in analyzing shapes in design decision space and CLIPS expert system shell in illustrating simple reasoning based on those design knowledge. We select target drawings from some of Frank Lloyd Wright’s block housing plans. In this experiment we try to illustrate a valid methodology that explicitly handles some of the implicit design knowledge hidden in architectural drawings.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 126-132
summary	This paper presents a research in progress in the development of parametric models for geometric manipulation of complex shapes, and introduces a methodology for evaluation of the design instances of a parametric model. The research presents a case study on the designs of the Spanish architect Antonio Gaudi, and takes on the fundamental rules of the form generation of the nave columns of the Expiatory Temple of the Sagrada Familia in Barcelona. The evaluation is done applying two provisos that determine if a shape is part of the design language and is an instance of the parametric model is a Gaudinian design.

summary	This paper presents a parametric shape grammar that explains the generation of the structural forms of the Spanish designer Santiago Calatrava. The shape grammar is divided into two separate grammars a lower level grammar and a higher level grammar. The lower level or first grammar is composed of rules to generate a “fundamental unit” design, which has the characteristic to be a single component with non-repetitive parts that becomes the primitive object of the design. The higher level or second grammar is composed of rules that generate the overall design by recursive application of Euclidean transformations to the fundamental unit. We concentrate our discussion on the higher level or second grammar to demonstrate the process of generating complex designs by application of simple rules.

title	Thonet Chairs Design Grammar: a Step Towards the Mass Customization of Furniture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 181-200.
summary	The paper presents the first phase of research currently under development that is focused on encoding Thonet design style into a generative design system using a shape grammar. The ultimate goal of the work is the design and production of customizable chairs using computer assisted tools, establishing a feasible practical model of the paradigm of mass customization (Davis, 1987). The current research step encompasses the following three steps: (1) codification of the rules describing Thonet design style into a shape grammar; (2) implementing the grammar into a computer tool as parametric design; and (3) rapid prototyping of customized chair designs within the style. Future phases will address the transformation of the Thonet’s grammar to create a new style and the production of real chair designs in this style using computer aided manufacturing. Beginning in the 1830’s, Austrian furniture designer Michael Thonet began experimenting with forming steam beech, in order to produce lighter furniture using fewer components, when compared with the standards of the time. Using the same construction principles and standardized elements, Thonet produced different chairs designs with a strong formal resemblance, creating his own design language. The kit assembly principle, the reduced number of elements, industrial efficiency, and the modular approach to furniture design as a system of interchangeable elements that may be used to assemble different objects enable him to become a pioneer of mass production (Noblet, 1993). The most paradigmatic example of the described vision of furniture design is the chair No. 14 produced in 1858, composed of six structural elements. Due to its simplicity, lightness, ability to be stored in flat and cubic packaging for individual of collective transportation, respectively, No. 14 became one of the most sold chairs worldwide, and it is still in production nowadays. Iconic examples of mass production are formally studied to provide insights to mass customization studies. The study of the shape grammar for the generation of Thonet chairs aimed to ensure rules that would make possible the reproduction of the selected corpus, as well as allow for the generation of new chairs within the developed grammar. Due to the wide variety of Thonet chairs, six chairs were randomly chosen to infer the grammar and then this was fine tuned by checking whether it could account for the generation of other designs not in the original corpus. Shape grammars (Stiny and Gips, 1972) have been used with sucesss both in the analysis as in the synthesis of designs at different scales, from product design to building and urban design. In particular, the use of shape grammars has been efficient in the characterization of objects’ styles and in the generation of new designs within the analyzed style, and it makes design rules amenable to computers implementation (Duarte, 2005). The literature includes one other example of a grammar for chair design by Knight (1980). In the second step of the current research phase, the outlined shape grammar was implemented into a computer program, to assist the designer in conceiving and producing customized chairs using a digital design process. This implementation was developed in Catia by converting the grammar into an equivalent parametric design model. In the third phase, physical models of existing and new chair designs were produced using rapid prototyping. The paper describes the grammar, its computer implementation as a parametric model, and the rapid prototyping of physical models. The generative potential of the proposed digital process is discussed in the context of enabling the mass customization of furniture. The role of the furniture designer in the new paradigm and ideas for further work also are discussed.

title	Towards Ornamatics

summary	Computer aided modelling and drafting protocols – in combination with new production technologies – have contributed to wholly new ways of shaping building elements. Some examples of new techniques, which have recently become very successful in building production and in architectural design education, are: 3D Rapid Prototyping; 2,5D and 3D Milling and computer aided Shape Cutting (notably using laser and water jet modes). Such new approaches not only create new opportunities for traditional production processes (including physical modelling), they also offer new perspectives for design and manufacturing on the level of architectural components and connections. We foresee innovative approaches to building product design, with a renewed interest in expressive Ornamentation. A phenomenological development we would like to address using the concept of ‘Ornamatics’. This contribution explores the potentials of product design with a renewed focus on ornamentation, involving the active utilization of computer aided modelling and manufacturing techniques. The paper furthermore documents results and findings of a series of explorative studies carried out within an educational laboratory environment.
