title Hearing Architectural Design: Simulation and Auralization for Generating Better Acoustic Spaces
source International Conference on Generative Art
summary This paper with demonstration is devoted to revealing and establishing the relationship between space and sound through computational acoustic analysis, simulation and electronic synthesis of audible sound. Based on science of acoustics and computing technology, acoustic effect of an architectural 3-D design can be analyzed and the resulted sound in space can be synthesized and predicted accordingly and being heard. Auralization refers to this process of acoustic analysis, sound synthesis and audio presentation of the result in the form of audible sound. Design alternatives can be experimented until satisfactory acoustic effect is achieved. Traditionally, designers rely on some minimum and vague understanding or specialists’ experiences to predict and design for a desirable sound behavior in spaces. Most likely acoustic design and analysis are seen as a luxury remedy only affordable in large-scale theatres and concert halls. The recent available PC based auralization tools brought significance in both in terms of new knowledge towards the science and art of architectural acoustics and the methods and practice in the design process. The examples demonstrated in the presentation will indicate that the auralization technology make it possible for the designers, consultants, end users or potential occupants to examine and evaluate the performance of different designs by hearing it directly before an informed decision can be made. The case studies also illustrated that the auralization is a powerful tool for general public with common building types to uncover everyday acoustic problems that have been constantly harming their well being and would otherwise be undetected.

title A catalogue of built forms, using a binary representation
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary A technique is described for the representation of a class of rectangular built forms. Each individual form is produced by applying a series of transformations to a single generic or ‘archetypal’ form, which is designed to take care of the broad constraints, on built space, of close-packing and the requirements for natural light and views. Parts of the archetype which are selected for inclusion in any particular built form are then designated by 1s, and parts which are suppressed by 0s. This makes it possible to assign a unique binary code to each different (undimensioned) built form produced from the archetype. Binary codes corresponding to all legitimate forms may then be arranged in ascending order, to create a comprehensive catalogue. The paper describes such a catalogue comprising forms with up to four courtyards, described by 22-digit binary strings. Metric values may be assigned to the various dimensions of each form, making it a matter of simple arithmetic to compute such attributes as volume, surface area, minimum site area or floor space index. From logical operations on the binary strings it is possible to identify a series of configurational characteristics of the corresponding forms, such as their overall plan shapes, the number of courtyards or the potential for symmetry. The catalogue may thus be searched for built forms fulfilling some set of specifications, for example total floor area, site size and certain desired shape attributes. Worked examples are illustrated from the design of multi-storey office buildings. Possible applications are suggested for this approach, in architectural science and the early strategic stages of architectural design.

title Applying Daylighting Simulation in Architectural Studio Education
doi https://doi.org/10.52842/conf.ecaade.2000.255
source Promise and Reality: State of the Art versus State of Practice in Computing for the Design and Planning Process [18th eCAADe Conference Proceedings / ISBN 0-9523687-6-5] Weimar (Germany) 22-24 June 2000, pp. 255-258
summary Computer generated simulation results are not necessarily valid design solutions. In some cases, unscientific “simulation” applications have misled designers to believe the “illusion” rendered by the system. This paper presents two case studies to highlight the pedagogy of architectural daylighting simulation. Both are located in Hong Kong’s highdensity urban context. Hong Kong is a small city, covering 1,097 square km with a population of 6.8 million. Mountains and hills dominate the topography, and more than 70% of the land is reserved for country parks. Property constraints encourage dense, high-rise construction and building on steep slopes. This creates a complex environment for daylighting design. Although the Buildings Ordinance specifies minimum standards for natural light and ventilation, residents have complained about the deterioration of their lighting condition in recent years. Challenged by the constraints imposed by Hong Kong’s physical environment, there is a need for students and professionals to explore computer simulation to integrate daylighting strategy into architectural and urban design.

summary ¿Can the computer improves the architectural creativity? This question is explored through a Virtual-Reality system developed for the modeling of timber structures, based on parametric elements, constructive programming and immersive visualization on real-time. Making experiences of evaluation with advanced students of architecture, whose use the system in the beginning of projects, compared with other group use not the system. This research faces the possibilities to rationalizate part of the creative process in architecture, broading the role of computer and its contribution to quality of design, and extending the possibilities to teach and share the creation of project. It is argue that major potential in this field is the swiftness, formal variety and spatial living of design, challenging the differences between objective and subjective.

title Virtual reality as a visualisation tool: Benefits and constraints
source CIDAC, Volume 2 Issue 4 November 2000 pp. 216-224
summary The benefits and applications of virtual reality (VR) in the construction industry have been investigated for almost a decade. However, the practical implementation of VR in the construction industry has yet to reach maturity owing to technical constraints. The need for effective information management presents challenges: both transfer of building data to, and organisation of building information within, the virtual environment require consideration. This paper reviews the applications and benefits of VR in the built environment field and reports on a collaboration between Loughborough University and South Bank University to overcome constraints on the use of the overall VR model for whole lifecycle visualisation. The work at each research centre is concerned with an aspect of information management within VR applications for the built environment, and both data transfer and internal data organisation have been investigated. In this paper, similarities and differences between computer-aided design (CAD) and VR packages are first discussed. Three different approaches to the creation of VR models during the design stage are identified and described, with a view to providing sharing understanding across the interdiscipliary groups involved. The suitable organisation of building information within the virtual environment is then further investigated. This work focused on the visualisation of the degradation of a building, through its lifespan, with the view to provide a visual aid for developing an effective and economic project maintenance programme. Finally consideration is given to the potential of emerging standards to facilitate an integrated use of VR. The convergence towards similar data structures in VR and other construction packages may enable visualisation to be better utilised in the overall lifecycle model.

title A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

title A Web Environment to Support User Participation in the Development of Apartment Buildings
source Special Focus Symposium on WWW as the Framework for Collaboration, InterSymp 2000, July 31-August 5, Baden-Baden, Germany, pp. 225-231
summary In Taiwan, apartments are sold before ever been built. Apartment buyers can customize their units until the construction takes place. This customization process has become a very unique form of user participation in the development of apartment buildings in Taiwan. However, in all customizations, large amount of information has to be documented and exchanged between related agencies for each apartment unit. For an apartment building that contains over 40 units, managing the information can be a daunting task. We are developing a web environment to support the customization process and enable efficient management and timely exchanges of information. The environment provides three levels of design interaction to encourage user participation in a controlled customization process. This paper describes the framework of this web environment, illustrates its functionality through a running prototype, and discusses technical issues encountered during its implementation.

source Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 665-671
summary New Technologies (NTs) offer us tools with which to deal with the new challenges that a changing society or workplace presents. In particular, new design strategies and approaches are required by the emerging Information Society, and NTs offer effective solutions to the designers in the different stages of their professional life, and in different working situations. In this paper some meaningful scenarios of the use of the NTs in Architecture and Urban Design are introduced; the scenarios have been selected in order to understand how the role of architects in the Information Society is changing, and what new opportunities NTs offer them. It will be underlined how the telematic networks play an essential role in the activation of virtual studios that are able to compete in an increasingly global market; examples will be given of the use of the Web to support activities related to Urban Planning and Management; it will be shown how the Internet may be used to access strategic resources for education and training, and sustain lifelong learning. The aforesaid considerations derive from a Web-Based Instruction system we have developed to support University students in the definition of projects that can concern either single buildings or whole parts of a city. The system can easily be adopted in the other scenarios introduced.

title The management and visualisation of 3-dimensional models using a spatial database
source CIDAC, Volume 2 Issue 4 November 2000, pp. 225-235
summary Each year, computer-aided architectural design (CAAD) systems in common use are enhanced and gain facilities that ease 3-dimensional (3D) modelling. Consequently, large complex datasets are increasinly common during the creation and management of 3D models of buildings and urban areas. Uses for such models range from the automatic generation of drawings and schedules to virtual reality (VR) and visualisation across the web. Geographic information systems (GISs) are optimised for the management and retrieval of spatial data and may be used to assist both management and visualisation of large 3D datasets using open standards, such as the ISO standard virtual reality modelling langauge (VRML). Experience gained in the use of such systems indicates a need for specific procedures for recording 3D data and creating linkages to other information. It is suggested that these procedures are applicable to a broad range of such models.

title Architectural Innovation as an evolutionary process
source International Conference on Generative Art
summary Traditionally in art and architectural history, innovation is treated as a history of ideas of individuals (pioneers), movements and schools. The monograph is in that context one of the most used forms of scientific exercise. History of architecture is then mostly seen as a succession of dominant architectural paradigms imposed by great architectural creators fighting at the beginning against mainstream establishment until they themselves come to be recognised. However, there have been attempts to place architectural innovation and creativity in an evolutionary perspective. Charles Jencks for example, has described the evolution of architectural and art movements according to a diagram inspired by ecological models. Philip Steadman, in his book "The Evolution of Designs. Biological analogy in architecture and the applied arts" (1979), sketches the history of various biological analogies and their impact on architectural theory: the organic, classificatory, anatomical, ecological and Darwinian or evolutionary analogies. This last analogy "explains the design of useful objects and buildings, particularly in primitive society and in the craft tradition, in terms of a sequence of repeated copyings (corresponding to inheritance), with small changes made at each stage ('variations'), which are then subjected to a testing process when the object is put into use ('selection')." However, Steadman has confined his study to a literature survey as the basis of a history of ideas. Since this pioneering work, new developments like Dawkins' concept of memes allow further steps in the field of cultural evolution of architectural innovation. The application of the concept of memes to architectural design has been put forward in a preceding "Generative Art" conference (Daru, 1999), showing its application in a pilot study on the analysis of projects of and by architectural students. This first empirical study is now followed by a study of 'real life' architectural practice. The case taken has a double implication for the evolutionary analogy. It takes a specific architectural innovative concept as a 'meme' and develops the analysis of the trajectory of this meme in the individual context of the designer and at large. At the same time, the architect involved (Eric Vreedenburgh, Archipel Ontwerpers) is knowledgeable about the theory of memetic evolution and is applying a computer tool (called 'Artificial') together with Remko Scha, the authoring computer scientist of the program who collaborates frequently with artists and architects. This case study (the penthouse in Dutch town planning and the application of 'Artificial') shall be discussed in the paper as presented. The theoretical and methodological problems of various models of diffusion of memes shall be discussed and a preliminary model shall be presented as a framework to account for not only Darwinian but also Lamarckian processes, and for individual as well as collective transmission, consumption and creative transformation of memes.

summary Understanding the dominant ethos of our age is imperative but not easy. However it is quite evident that new technologies have altered our times. Every discipline is now forced to be critical in developing new concepts according to the realities of our times. Implementing a critical worldview and consciousness is now more essential than ever. Latest changes in information technology are creating pressure on change both in societal and cultural terms. With its direct relation to these technologies, computer aided architectural design education, is obviously an outstanding / prominent case within contemporary debate. This paper aims to name some critical points related to computer aided architectural design education (CAADE) from the perspective of critical communication studies and critical education theories. It tries to relate these three areas, by introducing their common concepts to each other. In this way, it hopes to open a path for a language of critique. A critique that supports and promotes experimentation, negotiation, creativity, social consciousness and active participation in architectural education in general, and CAADE in specific. It suggests that CAADE might become critical and produce meta-discourses [1 ] in two ways. Firstly, by being critical about the context it exists in, that is to say, its relationships to the existing institutional and social structures and secondly by being critical about the content it handles; in other words by questioning its ideological dimensions. This study considers that analysing the role of CAADE in this scheme can provide architectural education with the opportunity to make healthy projections for the future.

summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title Development of a Wheelchair Virtual
source 3rd International Conference on Disability, VR and Associated Technologies, Sardinia, (Ed. P Sharkey) ICDVRAT2000, 1-8
summary In the UK the Disability Discrimination Act 1995 aims to end discrimination against disabled people. Importantly the Act gives the disabled community new employment and access rights. Central to these rights will be an obligation for employers and organisations to provide premises which do not disadvantage disabled people. Many disabled people rely on wheelchairs for mobility. However, many buildings do not provide conditions suited to wheelchair users. This project aims to provide instrumentation allowing wheelchair navigation within virtual buildings. The provision of such instrumentation assists architects in identifying the needs of wheelchair users at the design stage. Central to this project is the need to provide a platform which can accommodate a range of wheelchair types, that will map intended wheelchair motion into a virtual world and that has the capacity to provide feedback to the user reflecting changes in floor surface characteristics and slope. The project represents a collaborative effort between architects, bioengineers and user groups and will be comprised of stages related to platform design, construction, interfacing, testing and user evaluation.

title Evolutionary design systems: a conceptual framework for the creation of generative processes
source Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary This paper presents an conceptual framework for the construction of generative mapping processes as a basis for creating active design tools in the domain of architecture. Such generative processes are seen as key components within evolutionary systems that manipulate populations of alternative solutions in order to discover previously unexplored possibilities. Solutions are represented in two forms: as highly encoded genotypes referred to as design seeds and as decoded phenotypes referred to as design proposals. The generative process maps the design seed to the design proposal. The discussion of generative processes is in two parts. In the first part it is argued that any generative process that aims to create a wide range of solutions that differ from each other in fundamental ways must focus on a limited subcategory of possible designs. It is proposed that the endeavour to create active design tools demands that the focus be on the designer's highly personalised style, called a design-schema. The second part discusses how to uncover the essence of an architectural design-schema. In particular, it is argued that implicit and familiar aspects of buildings must be scrutinised in order to reveal the knowledge that is essential to capturing and codifying a design-schema. A range of rationalisations and conceptualisations of built form are presented with examples to illustrate possible routes of analysis. Finally, in conclusion, the possibility of discovering universal generators common to many divers generative processes are discussed.

title Case-Based Structural Design - using weakly structured product and process information
source Chalmers University of Technology, Division of Steel and Timber Structures, Publ. S 00:7, Göteborg
summary Empirical knowledge plays a significant role in the human reasoning process. Previous experiences help in understanding new situations and in finding solutions to new problems. Experience is used when performing different tasks, both those of routine character and those that require specific skill. This is also the case for structural designers. Over 50% of the work done by the designer on a day-to-day basis is routine design that consists of modifying past designs (Moore 1993). That is, most of the design problems that the designer solves have been solved before, in many cases over and over again. In recent years, researchers have started to study if cases (information about specific problem-solving experiences) could be used as a representation of experiential knowledge. Making use of past experience in the form of cases is commonly known as Case-Based Reasoning (CBR). A requirement for Case-Based Design (Case-Based Reasoning applied in design) to be successful is that the design information is computerized. One information type used in structural design that is starting to become computerized is the one in design calculation documents. Such information is weakly structured (which holds for much of the information representing experience) and it contains both product and process information. In this thesis it is shown how the weak structure of this information can be used to subdivide it into components, which in turn makes it possible to apply the object-oriented abstraction principles also to this kind of information. It is also shown how the detailed design process can be represented and how this representation can facilitate automatic acquisition, retrieval of relevant old design information, and adaptation of this information. Two prototypes BridgeBase and ARCADE have been developed, where the principles described above are applied. Using ARCADE, the more general of these two prototypes, it is presented how information in computerized design calculation documents, gathered from real projects, can serve as containers and carriers for both project information and experience. The experience from the two prototypes shows that Case-Based Design can be usable as a tool for structural engineers.

title Forming and automated energy analysis of integrated models of the public buildings and their enclosing structures
source Civil Engineering, 6(3), pp. 147-157
summary The article concerns the modelling and energy analysis problem of the spatial and structural solutions of newly designed buildings or those under renovation. The results of that task serve as a base for defining thermal indices of the project on different design stages. The core of the developed automated system is formed of integrated graphical digital spatial models of the parts of buildings. These models include different kind of structured geometric and non-geometric (physical, economical) information about the object. The proposed method could be used by interested experts as a tool for controll thermal and energy indices at various design stages, searching for rational architectural forms and structural solutions. It takes into account the latest requirements of Lithuanian building regulations concerning heating energy saving.

title Redirecting design generation in architecture
source International Conference on Generative Art
summary Design generation has been the traditional culmination of computational design theory in architecture. Motivated either by programmatic and functional complexity (as in space allocation) or by the elegance and power of representational analyses (shape grammars, rectangular arrangements), research has produced generative systems capable of producing new designs that satisfied certain conditions or of reproducing exhaustively entire classes (such as all possible Palladian villas), comprising known and plausible new designs. Most generative systems aimed at a complete spatial design (detailing being an unpopular subject), with minimal if any intervention by the human user / designer. The reason for doing so was either to give a demonstration of the elegance, power and completeness of a system or simply that the replacement of the designer with the computer was the fundamental purpose of the system. In other words, the problem was deemed either already resolved by the generative system or too complex for the human designer. The ongoing democratization of the computer stimulates reconsideration of the principles underlying existing design generation in architecture. While the domain analysis upon which most systems are based is insightful and interesting, jumping to a generative conclusion was almost always based on a very sketchy understanding of human creativity and of the computer's role in designing and creativity. Our current perception of such matters suggests a different approach, based on the augmentation of intuitive creative capabilities with computational extensions. The paper proposes that architectural generative design systems can be redirected towards design exploration, including the development of alternatives and variations. Human designers are known to follow inconsistent strategies when confronted with conflicts in their designs. These strategies are not made more consistent by the emerging forms of design analysis. The use of analytical means such as simulation, couple to the necessity of considering a rapidly growing number of aspects, means that the designer is confronted with huge amounts of information that have to be processed and integrated in the design. Generative design exploration that can combine the analysis results in directed and responsive redesigning seems an effective method for the early stages of the design process, as well as for partial (local) problems in later stages. The transformation of generative systems into feedback support and background assistance for the human designer presupposes re-orientation of design generation with respect to the issues of local intelligence and autonomy. Design generation has made extensive use of local intelligence but has always kept it subservient to global schemes that tended to be holistic, rigid or deterministic. The acceptance of local conditions as largely independent structures (local coordinating devices) affords a more flexible attitude that permits not only the emergence of internal conflicts but also the resolution of such conflicts in a transparent manner. The resulting autonomy of local coordinating devices can be expanded to practically all aspects and abstraction levels. The ability to have intelligent behaviour built in components of the design representation, as well as in the spatial and building elements they signify, means that we can create the new, sharper tools required by the complexity resulting from the interpretation of the built environment as a dynamic configuration of co-operating yet autonomous parts that have to be considered independently and in conjunction with each other.   P.S. The content of the paper will be illustrated by a couple of computer programs that demonstrate the princples of local intelligence and autonomy in redesigning. It is possible that these programs could be presented as independent interactive exhibits but it all depends upon the time we can make free for the development of self-sufficient, self-running demonstrations until December.

title InfoGEOMETRY. Conceptual Prototype for Navigating InfoSPACE
source International Conference on Generative Art
summary InfoGEOMETRY  is the word the authors use to describe the concept of utilizing geometric patterns and dynamic symmetry in graphical user interface design for navigating complex information. This paper refers to a specific collaborative project in which the concept of infoGeometry was first introduced as an alternative tool of information architecture. In their design process, the authors tried to reconcile the visual nature of geometric vocabulary with parametric nature of interface design and dynamic nature of information organization. The project resulted in experimental interactive tools for information search and navigating complex information structures. 2. YOU ARE HERE. A study in interactivity. This paper refers to a studio project in interface design, conducted at the Massachusetts College of Art in Boston, where individual designers explored essential concepts in navigating complex structures of information. Taking the notion of You-Are-Here as a point of departure, individual designers explored various definitions and interpretations of the notion's three components: You(We/They, etc)-Are(Will Be/Have Been, etc)-Here(in Time/in Space). Exploring specific instances of parametric design and developing linked, multiple representations for information display resulted in a broad spectrum of contexts associated with navigation. Specific descriptions of individual instances will accompany the final presentation of the project.

title Aesthetic Evolutionary Design with Data Flow Networks
source International Conference on Generative Art
summary For a little over a decade, software has been created which allows for the design of visual content by aesthetic evolutionary design (AED) [3]. The great majority of these AED systems involve custom software intended for breeding entities within one fairly narrow problem domain, e.g., certain classes of buildings, cars, images, etc. [5]. Only a very few generic AED systems have been attempted, and extending them to a new design problem domain can require a significant amount of custom software development [6][8]. High end computer graphics software packages have in recent years become sufficiently robust to allow for flexible specification and construction of high level procedural models. These packages also provide extensibility, allowing for the creation of new software tools. One component of these systems which enables rapid development of new generative models and tools is the visual data flow network [1][2][7]. One of the first CG packages to employ this paradigm was Houdini. A system constructed within Houdini which allows for very fast generic specification of evolvable parametric prototypes is described [4]. The real-time nature of the software, when combined with the interlocking data networks, allows not only for vertical ancestor/child populations within the design space to be explored, but also allows for fast "horizontal" exploration of the potential population surface. Several example problem domains will be presented and discussed. References: [1] Alias | Wavefront. Maya. 2000, http://www.aliaswavefront.com [2] Avid.
