title	How to Simulate and Realise a Disappeared City and City Life? - A VR Cave Simulation
source	CAADRIA 2002 [Proceedings of the 7th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 983-2473-42-X] Cyberjaya (Malaysia) 18–20 April 2002, pp. 301-308

summary	Computer simulation is used well in historical architecture restoration and research in a small scale for a long time, and should be used in a larger scale to represent a city, especially a disappeared city. Therefore how to utilize computers to coordinate both architectural and cultural data of a city becomes an important issue. This study takes Chang-an City that existed 1400 years ago but disappeared now as example and tries to develop a computerized and visualized method to simulate and realize a disappeared city and it’s life. Finally, we represent simulations in a virtual reality cave (VR Cave) to make navigators evolving in and interacting with the virtual Chang-An City.

title	Evaluating the Use of a Web-Based Collaborative Interactive Digital Model (CollABITA) in Supporting the Urban Design Approval Process1
source	UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, III.1-III.15
summary	This research, after analyzing the Urban Development Approval Process in its functionalities and methodologies, is showing the key points at which the process might be supported by new computer technologies, and it establishes a web-based Collaborative Interactive Digital Model (CollABITA Model) that relates and facilitates the graphical representation of the urban design process with some elements of the methodological approach. The CollABITA Model will dramatically facilitate the idea of broadening public participation, and indirectly by this, also collaboration. This new web-based support tool, is focusing on how new Informative Computer Technologies can be used in order to have a more co-operative design process. By utilizing the enormous potential of Internet for informing the process, and software for visualizing its products, the Model will provide an effective support, which will be able to deliver information in various forms to the Designers, Developers, Decision Makers, Agencies and the final user (the Citizens). The Model is concerned with the big challenge of supporting the urban design approval process itself, by exploring different kind of visualizations and communication tools, rather than producing a guide for carrying out the design. CollABITA Model is based on the existent framework structure of the extranet tool already available. Then, more then those, CollABITA Model will try to solve, by adding technical and collaborative functionalities, those issues that are characteristics in the urban design process and that are not jet solved by using one of the software .

summary	The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of disciplines, to find the explicitly spatial structures and relations in digital city upon physical city.

summary	The shape of town is the main issue which planners deal with. The function of some buildings and urban facilities is flexible, it changes in time. The appearance of city public areas and, what follows, the life conditions of its inhabitants, depends on elements of the town structure - the surrounding buildings, their density, state and form. All lasting elements of the city form its shape which reflects urban processes which have been taking place over ages. The aim of this paper is to define how latest computer technology can be used as an aid in the evaluation of the town landscape.

title	OBJECT-ORIENTED DATA MODELING AND WAREHOUSING TO SUPPORT URBAN DESIGN
source	Ph.D. Dissertation, School of Architecture, Carnegie Mellon University
summary	All over the world, local authorities are moving towards managing and storing urban data in digital form. But the data storage devices used are heterogeneous and typically include relational database management systems (DBMS), GIS and CAD files. As a result, data are present in different locations on different platforms and under different schemas. This poses a problem for software applications meant to support decision-making in urban design that require input from more than one data source. This dissertation demonstrates how data warehousing—combined with object-oriented data modeling—is able to provide a general solution for this problem. Data warehousing is a technique initially developed for business applications, but is equally useful for urban design: The data warehouse constitutes a communication layer between the urban design applications and data sources. It makes the data available through a unified interface that hides the sources themselves and represents that data in terms of a general-purpose, preferably object-oriented, model. The dissertation also describes an implementation prototype of the data model and the data warehouse. The test case of this research is the city of Makkah in Saudi Arabia, which faces significant urban design and planning issues in connection with the pilgrimage (Hajj) that brings millions of visitors to the city every year.

title	Investigação digital dos projetos do MESP: a busca dos vestígios do modernismo brasileiro [Digital exploration of MESP projects: the search for the Brazilian Modernism footprints]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 75-78
summary	This paper aims to demonstrate how the design process analysis of an important architectural icon of the city of Rio de Janeiro – the Ministry of Education and Public Health, MESP – allows the understanding of how the decisions taken during the design process synthesizes a way those involved in the project see the world, through an architectural artifact. This research presents, through 3D models, grouped in a hyperdocument, the project of that important Brazilian Modern Architecture icon. The 3D models were critical to the hypothesis development. They were a powerful tool to compare the different design versions while allowing projects with originally different forms of representation could be examined side by side from several equal point of views. Another important aspect of the investigation is the use of hyperdocument, through links of several document formats in an interactive way, to present the analysis.

summary	Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

title	A Study of the Accuracy of Daylighting Simulation of Heavily Obstructed Buildings in the Urban Canyons of Athens
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 456-463
doi	https://doi.org/10.52842/conf.ecaade.2002.456
summary	This paper deals with the use and evaluation of daylighting simulation tools in relation to a complex urban environment. The environment concerned is one commonly found in city centre areas where the proximity of buildings leads to the creation of ‘urban canyons’; the result of this is that assessment and simulation of daylight requires a more sophisticated approach than for other situations. In urban areas building layout is the most important factor effecting daylight, sunlight and solar heat gain reaching a building. It also affects sunlight in open spaces, ventilation, shelter and the dispersal of pollutants. In order to produce a more realistic understanding of the dynamic effects of daylight, there is a need not only for the research and development of advanced CAD and lighting simulation tools, but also of the study of possible alternative methods in their application. In the work reported in this paper, an attempt has been made to move the focus of lighting and daylighting simulation from the scale of a room to that of a whole building; the building itself being surrounded by its specific urban environment (including its microclimate). The study evaluates if there is sufficient evidence that it is possible with such complexity to reach reliable computation results after executing the simulation. The case study presented uses a 4D model of an urban canyon to investigate the sensitivity of such a complex simulation system. It can also be used to find ways to analyse and predict how daylight is reflected, refracted, scattered, diffused, polarised, diffracted and absorbed as it traverses an urban environment.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 63-66
summary	From 1959 to 1990, East St. Louis, Illinois deteriorated from an “All-American City” to a national symbol of urban blight. Located on the Mississippi River, the East St. Louis of today faces severe economic, social, and environmental problems. Nearly onequarter of the city’s work force is unemployed and about 40 percent of families are living below the poverty level. But East St. Louis was not always a distressed community. With strong ties to St. Louis and the surrounding region, East St. Louis onceflourished as the country’s second busiest railroad hub. Powerful economic and socio-political forces, as well as unfortunate historical circumstance, propelled the city into a downward spiral that drastically decreased the quality of life in East St. Louis. This paper presents the digital re-construction of the buildings and the analyses of the historical aspects of the housing construction and types in this area. Furthermore, it reports the survey and assessment of the quality of building stocks based on therevitalization plan that will provide some guidelines and suggestions for improvement, stability, and future needs.

title	Road hierarchy and speed limits in Brasília/Brazil
source	H.J.P. Timmermans, B. de Vries (eds.) 2008, Design & Decision Support Systems in Architecture and Urban Planning, ISBN 978-90-6814-173-3, University of Technology Eindhoven, published on CD
summary	This paper aims at exploring the theory of the Social Logic of Space or Space Syntax as a strategy to define parameters of road hierarchy and, if this use is found possible, to establish maximum speeds allowed in the transportation system of Brasília, the capital city of Brazil. Space Syntax – a theory developed by Hillier and Hanson (1984) – incorporates the space topological relationships, considering the city shape and its influence in the distribution of movements within the space. The theory’s axiality method – used in this study – analyses the accessibility to the street network relationships, by means of the system’s integration, one of its explicative variables in terms of copresence, or potential co-existence between the through-passing movements of people and vehicles (Hillier, 1996). One of the most used concepts of Space Syntax in the integration, which represents the potential flow generation in the road axes and is the focus of this paper. It is believed there is a strong correlation between urban space-form configuration and the way flows and movements are distributed in the city, considering nodes articulations and the topological location of segments and streets in the grid (Holanda, 2002; Medeiros, 2006). For urban transportation studies, traffic-related problems are often investigated and simulated by assignment models – well-established in traffic studies. Space Syntax, on the other hand, is a tool with few applications in transport (Barros, 2006; Barros et al, 2007), an area where configurational models are considered to present inconsistencies when used in transportation (cf. Cybis et al, 1996). Although this is true in some cases, it should not be generalized. Therefore, in order to simulate and evaluate Space Syntax for the traffic approach, the city of Brasília was used as a case study. The reason for the choice was the fact the capital of Brazil is a masterpiece of modern urban design and presents a unique urban layout based on an axial grid system considering several express and arterial long roads, each one with 3 to 6 lanes,

summary	In Taiwan, the National Science Council (NSC) has launched the “National Digital Archives Program” (NDAP) since 2002. We participated in two projects: “The 3D digital museum of Taiwan city and architecture” and “Digital model database and professional service for Taiwan city and architecture”. The first one attempted to build a virtual museum for Taiwan city and architecture through the past four hundred years. The second one was a value-added project which intended to further apply the digital contents of the previous one. This project was consisted of 3D refined data, digital knowledge database, and architecture professional service. We were responsible for the 3D refined data. As a result, the digital model database included three cities: Hsinchu, Chiayi, and Tainan, as well as sixty-four architecture models. The interactive entertainment platform is an important leisure in our daily life. In general, the interactive entertainment includes five types: arcade game, PC game, on-line game, TV game, and mobile entertainment. This research pays attentions to the arcade game which presents dynamic interactions between machine and users. Following the improvements of design techniques, we have opportunities to experience many arcade games with different purposes, such as drum game, dance game, and fishing simulator. However, we further apply the digital model database to create an interactive entertainment platform for a racing arcade game.

title	Pursuing New Urban Living Environment In The New Millennium: Projecting The Future Of High-Rise And High Density Living In Hong Kong
source	International Conference on Generative Art
summary	High-rise and high density living is a way of life for most of the 6.7 Million population of Hong Kong. The merits and demerits affiliated with Hong Kong’s compact urban form continues to attract academic deliberations and debates over the acceptability of such urban form as an alternative to urban sprawl for future city and urban life-style. This paper traces the development and causes for Hong Kong’s high-rise and high-density urban form over the past fifty years or so, and focuses its discussions on the pros and cons of high-rise living based on subjective user survey in late 2001 and early 2002. Because of an articulated land shortage, acute topography, escalating population growth, and shortage of time, Hong Kong government and planners have little options left but to adopt vertical development, resulted in a densely and mixed use urban habitat packed with closely built high-rise residences and commercial buildings. From the survey, it is clear that mixed and intensive land use, high quality of living and recreation infrastructure, efficient public transportation network, and segregation of pedestrian and traffic can facilitate the performance of compact urban form. In addition, most of Hong Kong families have been accustomed to high-rise living pattern and the disadvantages such living pattern might cause on its resident’s social communication and children education are readily ignored by most of the people. Based on the analysis of current living situation and development trends in Hong Kong, new pattern of future city form is conceived to be a likely applicable development way in a coastal city with such high density as Hong Kong in the next 50 years. Design countermeasures are presented in this paper to suggest ways of alleviating the pressure of the forever-increasing house requirements in Hong Kong. high-density, high-rise, compact city, social acceptance, life-style.

title	An Informal Shape Grammars for Interpolations of Traditional Bosnian Hayat Houses in a Contemporary Context
source	International Conference on Generative Art
summary	This paper explores the use of an informal shape grammar method for Hayat house form interpolations. Interpolations are new house forms, which carry stylistic characteristics of an existing design language but are inserted into a context, which responds to a contemporary life style. The study is based on a corpus of eight Hayat houses designed in the classic Ottoman style in the 18th and 19th century in Sarajevo. The hayat is a large shaded gallery open to the garden. It occupies the most important place in the composition of the plan. In this study, a form-driven design strategy is applied. The emphasis is given to new house form generation. The generation of a new house form within the grammar proceeds in four steps: (1) Primitive hayat house generation, (2) sub-house generation, (3) House variations, (4) House development. The shape rules used in the process of hayat house interpolations are mostly informal and explain in general terms how certain parts of the form are modified.

title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title	Can a Genetic Algorithm Think Like a Composer?
source	International Conference on Generative Art
summary	There has now been a substantial body of work utilising Genetic Algorithms (GA) for the purpose of musical composition. A common point of discussion is how far GA’s can simulate not just the musical output of human composers, but also the process of composing itself. This paper begins by discussing the suitability of using a GA for composition, and goes on to describe a generative music system (by the author), that utilises a domain specific, knowledge rich GA. The system acts on a supplied 2-bar musical phrase (up to 4 parts), and evolves musical fragments towards a supplied target. The aim is to provide interim points on the evolutionary path, which represents a ‘new’ musical ideas audibly based on the supplied fragments. The paper concludes that the system is able to model at least part of the creative process of composition, and is effective at producing musically successful results. (Audio download sources of its output are included to support this conclusion). The system was used to generate music included in an interactive installation work, exhibited at Brighton Arts Festival 2002, and other applications under developed that use the algorithm are 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	Generative Architectural Design and Complexity Theory
source	International Conference on Generative Art
summary	During the past decades, complexity theory has evolved as a new discipline that provides a broad scientific perspective towards dynamic real-life phenomena, challenging the classical linear worldview as well as simple cause-and-effect-style Newtonian physics. For architects, the advent of this new science offers the challenge as well as the chance to reconsider common design approaches and to invent new strategies based on the new paradigms. The actual application of complexity theory to architectural design, however, results in a fundamental dilemma: How can a reflective, ultimately retrospective body of thought (complexity theory) be applied to prospective design challenges (architecture)? Being part of a current MArch thesis project, the proposed paper focuses on this general dilemma between architectural design and complexity theory and discusses actual as well as potential future generative architectural design approaches involving complexity theory. Generative design strategies commonly apply algorithmic methods and formalisms, which can conveniently produce and deal with high levels of complexity. Complexity describes general properties of a system and can be further dissected into several modes: epistemic, ontological and functional complexity. This taxonomy offers insights into generative design applications, which have mostly focused on a limited set of complexity modes. Besides complexity generated by sheer numbers, aspects like functional or hierarchical complexity offer further perspectives on generative systems, processes and output. Considering these aspects of complexity theory, future challenges to generative architectural design can be predicted.

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN The adaptation of the word cyberspace (Gibson, 1984) following the emergence of the World Wide Web Internet not only succinctly revolutionized the correlation of time and space but also poised to challenge how we view the existing spatial concept. This research tries to use protocol analysis to examine text-based cyberspace, such as bulletin board, chart rooms and so forth, and the objective of this research is to realize the spatiality of cyberspace through the cognitive point of view, and to compare the differences of the definitions and perception ways of spatiality between people with general domain and in design fields. Finally, we validate the existence of cyberspace, where the process not only allows further categorization of spatial elements concluded from the earlier study, but discover that varied backgrounds can affect how a user defines and perceives cyberspace (Strate, 1999).
