title	From Bézier to NURBS: Integrating Material and Digital Techniques through a Plywood Shell
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 156-169

summary	The development of digital fabrication has reintroduced material processes with digital processes. There has been much discussion about the tool and the objects of the tool, but little discussion of the implication of the material process on the digital process. A brief historical review on the development of computer numerical control and the origins of the Bézier curve reveals an instrumental fact: computer numerical controlled tools necessitated advancements in computational surfaces which eventually led to NURBS (Non-Uniform Rational B-Splines) surfaces. In other words, the origins of NURBS surfaces resides in its relation to material processes, rather than many current approaches that develop free form surfaces and then force the tool onto the material without regard to the material properties. From this historical and mathematical review, this project develops toward more intelligent construction methods based on the integration of NURBS differential geometry paired with material qualities and processes. Specifically, a digital technique of developing conceptual NURBS geometry into piecewise surface patches are then flattened based on the material thickness and density. From these flattened patches, a material technique is developed to intelligently remove material to allow the rigid flat material to re-develop into physical surface patches. The goal of this research is to develop digital and material techniques toward intelligent construction based on the correspondence between digitally driven surface and digitally driven material processes. The application of this technique as a rational and flexible system is to support the dynamic response of form and material toward such performative aspects as structure, daylight, ventilation, and thermal properties.

title	A Computational Approach to the Reconstruction of Surface Geometry from Early Temple Superstructures
source	International Journal of Architectural Computing vol. 3 - no. 4, 471-486
summary	Recovering the control or implicit geometry underlying temple architecture requires bringing together fragments of evidence from field measurements, relating these to mathematical and geometric descriptions in canonical texts and proposing "best-fit" constructive models. While scholars in the field have traditionally used manual methods, the innovative application of niche computational techniques can help extend the study of artefact geometry. This paper demonstrates the application of a hybrid computational approach to the problem of recovering the surface geometry of early temple superstructures. The approach combines field measurements of temples, close-range architectural photogrammetry, rule-based generation and parametric modelling. The computing of surface geometry comprises a rule-based global model governing the overall form of the superstructure, several local models for individual motifs using photogrammetry and an intermediate geometry model that combines the two. To explain the technique and the different models, the paper examines an illustrative example of surface geometry reconstruction based on studies undertaken on a tenth century stone superstructure from western India. The example demonstrates that a combination of computational methods yields sophisticated models of the constructive geometry underlying temple form and that these digital artefacts can form the basis for in depth comparative analysis of temples, arising out of similar techniques, spread over geography, culture and time.

title	Crisis? What Crisis?
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 547-556
doi	https://doi.org/10.52842/conf.ecaade.2005.547
summary	The paper describes the current situation concerning career opportunities in the field of architecture in developed western countries. Several aspects that are almost universal mark this situation. Firstly, there are too many architects chasing traditional work in competition with structural (civil) engineers. This is not surprising in consideration of the fact, that the architectural education industry produces far too many new architects for the economy to absorb. In Germany, the number is almost three times too many. Secondly, the needs of the building industry have changed over the past twenty years so that the skills that architects want to offer are not necessarily those that are sought. Lastly, the constant specialisation of work has continued unabated. Architects, as generalists, have idly watched their areas of expertise be usurped from neighbouring fields like civil and structural engineering The reasons for this crisis are manifold. In the schools of architecture, the discussions often deal with form or formal arguments, which, in fact, have little or no relevance to the building industry. This position was tenable so long as the clients were willing to accept formal arguments in order to receive buildings of high quality or current social relevance (i.e. current architectural fashion). With the dual aspects of globalisation and a shift to maintaining building stocks rather than producing new buildings, the tolerance for “architectural” discussions has been reduced even further. Indeed, the monetary pressures overwhelm almost all other aspects, including so-called green issues. What is more, most of the monetary issues are time based. Time represents, perhaps, the largest pressure in any current planning project. The clients expect expedient, accurate and inexpensive solutions. If architects are not able to produce these, the clients will (and do) go elsewhere. The authors argue that there remain serious problems to be solved for architects and the metier in general. Ever cheaper, ever faster and ever encompassing information technologies offer the architectural community a chance to turn recent trends on their head. By using information technologies to their full potential, architects can reassert themselves as the coordinators of building information and processes. Simply put, this means less photorealistic rendering and more databases, which may be unappealing for those architects who have positioned themselves as “designers” and are able to talk long on form, but short on cost or logistics. Nonetheless, the situation is not lost, so long as architects are able to recognise what is desired from the point of view of the client and what is desired from the point of view of the architect. It is not a question of one or the other. Architects must be able to offer innovative design solutions that not only address the fiscal, legal and programmatic constraints, but also push the boundaries at to the position of architecture in the community at large. For educators, it must be made clear that the real potential architects possess is their encompassing knowledge of the building process including their expertise concerning questions of architectural form, function, history and art. Precisely while they are generalists are architects invaluable in a sea of specialists. The biggest hurdle to asserting this in the past has been the control of the vast amounts of information. This is no longer a problem and also no longer an excuse. In the education of architects, it must be made clear that their role dictates sovereignty over architectural information. Architectural Information Management is a necessary skill alongside the more traditional architectural skills. A brief outlook as to how this might come about is detailed in the paper. The authors propose didactic steps to achieve this. Primarily, the education of computer supported planning should not simply end with a series of lectures or seminars, but culminate in integrated Design Studios (which including Design-Build scenarios).

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.

title	iSphere: A Proximity-based 3D Input Interface
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. 281-290
summary	This paper presents a 24 degree of freedom input device for 3D modeling. iSphere uses the proximity information of pulling-out and pressing-in capacitive sensors to manipulate 12 control points of a 3D surface simultaneously . The iSphere dodecahedron is demonstrated manipulating an analog parametric model with high-level modeling concepts like push or pull the 3D surfaces. Our pilot experiment shows that iSphere saved many steps of selecting the control point and going through menus. Experts were used to those extra steps and still found themselves doing them but novices saved significant time for surface shaping tasks. 3D systems are benefited to execute high-level modeling commands, but lacking of fidelity is a great issue of analog input device.

title	Interfacing with the real space and its performance
source	International Journal of Architectural Computing vol. 3 - no. 1, 43-56
summary	This paper presents an immersive gesture-recognition-based system to visualize the indoor thermal environment using Computational Fluid Dynamics (CFD). To enable efficient visualization of CFD in actual space, an Augmented Reality system was integrated with a CFD simulation engine. To facilitate efficient data manipulation of the simulated postprocessed CFD data and to increase user control of the immersive environment, an intuitive method of Human-Computer Interaction (HCI) has been incorporated using gesture and speech recognition. While gesture recognition aids in transforming hand postures into command functions through forward kinematics and computation of hand segment positions and their joint angles, speech recognition allows better control of the data manipulation. This enabled real-time interactions between the users and simulated CFD results in actual space.

title	Townscaping: Development of Dynamic Virtual City Augmented 3D Sketch Design Tools
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. 105-114
summary	The paper presents the development of an experimental Web-based design environment called Townscaping to be used at the conceptual stage of architectural and urban design. Inspired by Gordon Cullen's seminal work on Townscape (1960's-1970's), the idea of Townscaping is to explore how 3D digital sketch design tools could be developed to operate in connection with a dynamic virtual city system under a user's direct control. A prototype of Townscaping has been designed and implemented on the basis of an existing dynamic virtual city system. In Townscaping, a set of tools is provided for users to create and edit 3D graphic elements to be positioned directly onto the user-specified virtual city models. One of the key features of Townscaping is to enable sketching while navigation: designers can perform sketch design and gain immediate visual feedback while navigating the 3D virtual city models to any viewpoint at any moment. The current study suggests that it is feasible for virtual city models to serve as interactive urban contexts for 3D sketch design. Townscaping is considered primarily a research platform with which we are interested in investigating if designers' engaging in 3D space conceptions may be enhanced through interacting and sketching with virtual townscapes.

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.

title	Structured Reflection as a Means to Deepen Understanding of CAAD
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 287-294
doi	https://doi.org/10.52842/conf.ecaade.2005.287
summary	In this paper we outline a strategy of structured reflection to improve reflection by students in a course on the implication of CAAD, design theory, and design methodology. Earlier editions of the course showed that students often did not evolve their learning beyond a checklist level. Reflection is an important mechanism to improve learning from design situations. After a consideration of the main approaches to design reflection, we take up Schön’s notion of reflection and provide support for structured reflection in CAAD education, based on earlier experiences with structured question lists in a civil engineering course. Findings after the first year’s run show a deeper level of reflection on a more elaborate level.

title	Towards a BIM-Based Energy Rating System

summary	Governments in Australia are faced with policy implementation that mandates higher energy efficient housing (Foran, Lenzen & Dey 2005). To this effect, the National Construction Code (NCC) 2013 stipulates the minimum energy performance for residential buildings as 114MJ/m2 per annum or 6 stars on an energy rating scale. Compliance with this minimum is mandatory but there are several methods through which residential buildings can be rated to comply with the deemed to satisfy provisions outlined in the NCC. FirstRate5 is by far the most commonly used simulation software used in Victoria, Australia. Meanwhile, Building Information Modelling (BIM), using software such as ArchiCAD has gained a foothold in the industry. The energy simulation software within ArchiCAD, EcoDesigner, enables the reporting on the energy performance based on BIM elements that contain thermal information. This research is founded on a comparative study between FirstRate5 and EcoDesigner. Three building types were analysed and compared. The comparison finds significant differences between simulations, being, measured areas, thermal loads and potentially serious shortcomings within FirstRate5, that are discussed along with the future potential of a fully BIM-integrated model for energy rating certification in Victoria.

title	Filmic Development of Architectural Animations
source	International Journal of Architectural Computing vol. 3 - no. 3, 299-316
summary	This paper proposes a general method to make animated presentations of architectural designs, based on cinematographic techniques. Particularly, it reviews theoretical documenttion about filmmaking as well as several productions that exhibit remarkable locations. The proposed method first comprises of a planning stage, with the narrative and graphic formulation of the presentation. Next is an elaboration or adjustment stage for the digital modelling of the design, and finally, there is an animation production and editing stage. Likewise, the research sets up a computer implementation of some activities and characteristics, and experiments in the programming of camera movements for architectural animations. In general, this work suggests focusing on the communication of the qualitative features of the design, instead of the elaboration of the digital model, and on emphasizing the visual diversity, graphic style and narrative construction of the presentation.

source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 400-404
summary	This exposé introduces preparations for a publication based on what I have found to be a ‘missing link’ in the library of educational source materials. The skills necessary to record and interpret the complexity of the architectural design process are often illusive. The sophistication of computer modeling and graphics applications only adds to the dilemma of making clear and concise decisions about how to communicate the essence of one’s design intent. The publication will define and illustrate five Diagraphic models of analysis. Each offers ways of seeing and understanding the idiosyncrasies of recording the design process. Gestures, Traces, Pulls, Morphs and Transits exemplify specific modes of visual expression and integrate both their diagrammatic and graphic nature. The distinctive aspects of each model enable the student of architecture to choose appropriate and meaningful techniques for visual expression. The publication will also illustrate current and historically relevant examples of diagrammatic expression. These examples show how diagrams have been flexible over time in adapting to the needs of newly forming conceptual models, spatial analysis and belief systems.

summary	Cities are becoming more complex in this digital era due to technological changes. Thinking of cities without such technological changes is equivalent to an embryonic state in the morphology of city growth, that is, the growth seems less advanced. So it is appropriate to think of the non digital city digitally. Urban design is one state which establishes the perfect relationship between the street, people and building. The relationship of the people with the building and street is becoming one of the key factors in architecture. It has been observed that the design of a city has been influenced by the pedestrian movement. Many cities prior to the industrial era were largely determined by the social interactions based on walking. Thus the pedestrians play a key role in the formation of the city. They are a very important component in any representation of transport movements. They generally terminate or initiate a chain of linked activities, and if observed carefully, a single pedestrian movement is meant to include various sub journeys from one location to another. In order to organize pedestrians, we need to understand the pedestrian movement system. Though there is a lot of development of urban models in this aspect, it is still in a nascent state in comparison with the digital advancement. Thus much research work is carried out which can be applied to any given environmental setting, and as a result urban designers can respond to the changing socio-cultural technologies.

title	Responsiveness and Social Expression; Seeking Human Embodiment in Intelligent Façades
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 12-23
doi	https://doi.org/10.52842/conf.acadia.2005.012
summary	This paper is based on a comparative analysis of some twenty-six intelligent building facades and sixteen large media-facades from a socio-psychological perspective. It is not difficult to observe how deployment of computational technologies have engendered new possibilities for architectural production to which surface-centeredness lies at that heart of spatial production during design, fabrication and envelope automation processes. While surfaces play a critical role in contemporary social production (information display, communication and interaction), it is important to understand how the relationships between augmented building surfaces and its subjects unfold. We target double-skin automated facades as a distinct field within building-services and automation industry, and discuss how the developments within this area are over-occupied with seamless climate control and energy efficiency themes, resulting into socially inert mechanical membranes. Our thesis is that at the core of the development of automated façade lies the industrial automation attitude that renders the eventual product socially less engaging and machinic. We illustrate examples of interactive media-façades to demonstrate how architects and interaction designers have used similar technology to turn building surfaces into socially engaging architectural elements. We seek opportunities to extend performative aspects of otherwise function driven double-skin façades for public expression, informal social engagement and context embodiment. Towards the end of the paper, we propose a conceptual model as a possible method to address the emergent issues. Through this paper we intend to bring forth emergent concerns to designing building membrane where technology and performance are addressed through a broader cultural position, establishing a continual dialogue between the surface, function and its larger human context.

title	Adaptive Generative Patterns: design and construction of Prague Biennale pavilion
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	This paper describes an experimental practice-based research project that considered design process, implementation and construction of a pavilion built to be part of the Performative Space section of the International Biennale of Contemporary Art, Prague 2005. The project was conceptualized as a time-bound performative situation with a parasite-like relationship to its host environment. Its design has emerged through an innovative iterative process that utilized digital simulative and procedural techniques and was formed in response to place-specific behavioral challenges. This paper presents the project as an in-depth case-study of digital methods in design, mass customization and unified methods of production. In particular, it considers the use of Voronoi patterns for production of structural elements providing detail on programming and construction techniques in relationship to design aspirations and practical constraints.

title	Computer Renderings – „Reality is Overrated”
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 729-735
doi	https://doi.org/10.52842/conf.ecaade.2005.729
summary	In this paper, two problems concerning truthfulness of computer-generated visualization are considered. The first one concerns relationships between reality and its representation by computer renderings. The second problem concerns the kind of representations people need. These problems are analyzed for static perception of architectural forms based on computer visualization, and for dynamic walk-through perception of urban space. The thesis of the paper is that many photorealistic renderings are excessively realistic and thus not true. In this context, a new question arises: do we need the true representation of an object? The author claims that we need “adequate” pictures. Adequate means a picture that is satisfactory in particular situation. The problem of equivalence of media (renderings and animations) and reality is not that important here. Much research is concerned with the truthfulness and falsity of information. However, they do not take into consideration that frequently what seems to be real exerts bigger influence on people than what is in fact real. Understanding this problem may help us in producing images that better correspond to people’s expectations.

summary	Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

title	Urban Grammars: Towards Flexible Urban Design

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.
