title	GA2: a Programming Environment for Abstract Generative Fine Art
source	International Conference on Generative Art
summary	Fine artists looking to use computers to create generative works, especially those artists inclined towards abstraction, often face an uncomfortable choice in the selection of software tools. On the one hand there are a number of commercial and shareware programs available which implement a few techniques in an easy to use GUI environment. Unfortunately such programs often impose a certain look or style and are not terribly versatile or expressive. The other choice seems to be writing code from scratch, in a language such as c or Java. This can be very time consuming as every new work seems to demand a new program, and the artist's ability to write code can seldom keep pace with his ability to imagine new visual ideas. This paper describes a software system created by the author called GA2 which has been implemented in the Matlab software environment. By layering GA2 over Matlab the artist can take advantage of a very mature programming environment which includes extensive mathematical libraries, simple graphics routines, GUI construction tools, built-in help facilities, and command line, batch mode, and GUI modes of interaction. In addition, GA2 is very portable and can run on Macintosh, Windows, and Unix systems with almost no incremental effort for multi-platform support. GA2 is a work in progress and an extension of the completed GA1 environment. It is medium independent, and can be used for all manner of image, animation, and sound production. GA1 includes a complete set of genetic algorithm operations for breeding families of graphical marks, a database function for managing and recalling various genes, a set of statistical operations for creating various distributions of marks on a canvas or animation frame, a unique Markov-chain-likeoperator for generating families of visually similar lines or paths, and a complete L-system implementation. GA2 extends GA1 by adding more generative techniques such as tiling and symmetry operations, Thom's cusp catastrophe, and mechanisms inspired by complexity science notions such as cellular automata, fractals, artificial life, and chaos. All of these techniques are encapulated in genetic representations. This paper is supplemented with examples from the authors art work, and comments on the philosophy behind this method of working, and its relation towards the reinvigoration of abstraction after post-modernism.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
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	Digital architectural visualization
source	Automation in Construction 9 (4) (2000) pp. 347-360
summary	The democratization of computer technologies is changing architectural visualization in two significant ways. The first is that the availability of digital media promotes wider and intensive application of computer visualization. The second concerns the extension of architectural design to visualization in information systems. The transition from analogue to digital visualization relates to fundamental questions ranging from the role of geometric representations in architecture and the relationships between analysis and visualization to the structure of abstraction. In addition, it requires technology and knowledge transfer also from areas other than computer science. The integration of such transfers suggests a flexible, modular approach that contradicts the holistic, integral principles of computer-aided architectural design.

title	Situatedness: A New Dimension for Learning Systems in Design

summary	In this paper we adopt the approach that designing is a series of situated acts, ie designing cannot be pre-planned to completion. This is based on ideas from situated cognition theory that claims that what people perceive, how they conceive and what they do develop together and are adapted to the environment. For a system to be useful for human designers it must have the ability to associate what is learned to its environment. In order for a system to do that such a system must be able to acquire knowledge of the environment that a design constructs. Therefore, acknowledging the notion of situatedness is of importance to provide a system with such capability and add on a new dimension to existing learning systems in design. We will call such a learning system within the design domain a Situated Learning Design System (SLDS). A SLDS should be able to create its own situational categories from its perceptual experiences and modify them if encountered again to link the learned knowledge to its corresponding situation. We have chosen architectural shapes as the vehicle to demonstrate our ideas and used multiple representations to build a platform for a SLDS to learn from. In this paper the notion of situatedness and its role in both designing and learning is discussed. The overall architecture of a SLDS is introduced and how the potential outcome of such a system will support human designers while designing is discussed.

title	Representation in Architecture: A Data Model for Computer-Aided Architectural Design
source	DDes Thesis, Harvard Design School, Cambridge, MA
summary	Traditional representation systems – including technical drawings, perspectives, models and photography – have historically been used by architects to communicate projectual ideas to other agents in the process, as well to communicate ideas to themselves and recording them for future reference. The increasing complexity of the projects, involving more agents in ever more distant locations; the need for a greater semantic richness to express all the subtleties of the technical, cost and styling details; and -- most importantly – the introduction of computers in every day practice, which enable powerful data generation and manipulation; all these factors together demand for a new representation system adapted to the new digital medium. Yet, traditional CAAD software packages do not offer a solution to any of these problems, for their data model is too simplified to model complex projects and ideas, and are based on geometrical representations of the built environment. This dissertation addresses the issue of computer representation of architecture, and tries to refocus the discussion from a “geometric representation of objects” to a “representation of relationships among objects.” After studying the nature of design, it is observed that objects in the built environment can be represented as patterns of relationships. Based on the object-oriented data model (OODM), which can capture such relationships, the research proposes a new data model and a new set of abstractions of architectural elements that represent the patterns of relationships among them. The resulting representations are networks of design concepts and intentions, hypertext-like structures conveying all the semantic richness of the architectural project, containing qualitative as well as quantitative information. It is analogous to a “digital writing” or “encoding” of architecture. Being stored in an OO, centralized, concurrent database, these object models can be shared and exchanged among design professionals, adding up to a universal computer-readable design representation system.

summary	Much of the debate and argument among CAAD researchers has turned on the degree to which CAAD systems limit the ways in which designers can express themselves. By defining representations for design objects and design functions, systems determine what it is possible to describe. Aart Bijl used the term 'prescriptiveness' to refer to this property of systems, and the need to overcome it was a major preoccupation of research at EdCAAD during the 1980s, including the development of the MOLE (Modelling Objects with Logic Expressions) system. But in trying to offer designers the freedom that was judged to be essential to evolving design practices, MOLE transferred much of the burden of programming from system developers to end-users - you can have any design objects you want, as long as you write the code. Close examination of MOLE's logic reveals that it too had to rely on fundamental definitions that, even if not domain-specific, are certainly historically contingent. This paper will return to the issue of prescriptiveness, summarising the lessons learned from the MOLE 'experiment,' and identifying new prescriptions that are deciding what designs can be. Looking beyond computer representations, we find that designs are shaped by much larger, and arguably more powerful, historical, social and cultural forces surrounding design practice. These forces are shaping the way CAAD is used and how new systems are conceived and developed.

title	Digital Tectonic Design
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. 287-290
doi	https://doi.org/10.52842/conf.ecaade.2000.287
summary	Digital tectonic design is a fresh approach to architectural design methodology. Tectonics means a focus on assemblies of construction elements. Digital tectonics is an evolving methodology that integrates use of design software with traditional construction methods. We see digital tectonic design as a systematic use of geometric and spatial ordinances, used in combination with details and components directly related to contemporary construction. The current approach will, we hope, lead to an architectural curriculum based on generative form making where the computer can be used to produce systems of forms algorithmically. Digital design has tended to remain abstract, emphasizing visual and spatial arrangements often at the expense of materials and construction. Our pursuit is translation of these methods into more fully realized physical qualities. This method offers a rigorous approach based on close study of geometry and building construction elements. Giving a context for this approach, historical examples employing systematic tectonic design are explored in this paper. The underlying geometric ordinance systems and the highly tuned relationships between the details in these examples offer design vocabularies for use within the studio curriculum. The paper concludes with a detailed example from a recent studio project demonstrating particular qualities developed within the method. The method involves a wide range of scales, relating large-scale gestural and schematic studies to detailed assembly systems. Designing in this way means developing geometric strategies and, in parallel, producing detailed symbols or objects to be inserted. These details are assembled into a variety of arrays and groups. The approach is analogous to computer-aided designÕs tradition of shape grammars in which systems of spatial relationships are used to control the insertion of shapes within a space. Using this approach, a three-dimensional representation of a building is iteratively refined until the final result is an integrated, systematically organized complex of symbols representing physical building components. The resulting complex offers substantial material qualities. Strategies of symbol insertions and hierarchical grouping of elements are familiar in digital design practice. However these strategies are usually used for automated production of preconceived designs. In contrast to thsse normal approaches this presentation focuses on emergent qualities produced directly by means of the complex arrays of symbol insertions. The rhyth

title	Swarm modelling. The use of Swarm Intelligence to generate architectural form
source	International Conference on Generative Art
summary	.neither the human purposes nor the architect's method are fully known in advance. Consequently, if this interpretation of the architectural problem situation is accepted, any problem-solving technique that relies on explicit problem definition, on distinct goal orientation, on data collection, or even on non-adaptive algorithms will distort the design process and the human purposes involved.' Stanford Anderson, "Problem-Solving and Problem-Worrying". The works concentrates in the use of the computer as a perceptive device, a sort of virtual hand or "sense", capable of prompting an environment. From a set of data that conforms the environment (in this case the geometrical representation of the form of the site) this perceptive device is capable of differentiating and generating distinct patterns in its behavior, patterns that an observer has to interpret as meaningful information. As Nicholas Negroponte explains referring to the project GROPE in his Architecture Machine: 'In contrast to describing criteria and asking the machine to generate physical form, this exercise focuses on generating criteria from physical form.' 'The onlooking human or architecture machine observes what is "interesting" by observing GROPE's behavior rather than by receiving the testimony that this or that is "interesting".' The swarm as a learning device. In this case the work implements a Swarm as a perceptive device. Swarms constitute a paradigm of parallel systems: a multitude of simple individuals aggregate in colonies or groups, giving rise to collaborative behaviors. The individual sensors can't learn, but the swarm as a system can evolve in to more stable states. These states generate distinct patterns, a result of the inner mechanics of the swarm and of the particularities of the environment. The dynamics of the system allows it to learn and adapt to the environment; information is stored in the speed of the sensors (the more collisions, the slower) that acts as a memory. The speed increases in the absence of collisions and so providing the system with the ability to forget, indispensable for differentiation of information and emergence of patterns. The swarm is both a perceptive and a spatial phenomenon. For being able to Interact with an environment an observer requires some sort of embodiment. In the case of the swarm, its algorithms for moving, collision detection, and swarm mechanics conform its perceptive body. The way this body interacts with its environment in the process of learning and differentiation of spatial patterns constitutes also a spatial phenomenon. The enactive space of the Swarm. Enaction, a concept developed by Maturana and Varela for the description of perception in biological terms, is the understanding of perception as the result of the structural coupling of an environment and an observer. Enaction does not address cognition in the currently conventional sense as an internal manipulation of extrinsic 'information' or 'signals', but as the relation between environment and observer and the blurring of their identities. Thus, the space generated by the swarm is an enactive space, a space without explicit description, and an invention of the swarm-environment structural coupling. If we consider a gestalt as 'Some property -such as roundness- common to a set of sense data and appreciated by organisms or artefacts' (Gordon Pask), the swarm is also able to differentiate space 'gestalts' or spaces of some characteristics, such as 'narrowness', or 'fluidness' etc. Implicit surfaces and the wrapping algorithm. One of the many ways of describing this space is through the use of implicit surfaces. An implicit surface may be imagined as an infinitesimally thin band of some measurable quantity such as color, density, temperature, pressure, etc. Thus, an implicit surface consists of those points in three-space that satisfy some particular requirement. This allows as to wrap the regions of space where a difference of quantity has been produced, enclosing the spaces in which some particular events in the history of the Swarm have occurred. The wrapping method allows complex topologies, such as manifoldness in one continuous surface. It is possible to transform the information generated by the swarm in to a landscape that is the result of the particular reading of the site by the swarm. Working in real time. Because of the complex nature of the machine, the only possible way to evaluate the resulting behavior is in real time. For this purpose specific applications had to be developed, using OpenGL for the Windows programming environment. The package consisted on translators from DXF format to a specific format used by these applications and viceversa, the Swarm "engine", a simulated parallel environment, and the Wrapping programs, to generate the implicit surfaces. Different versions of each had been produced, in different stages of development of the work.

title	Music Generation through Cellular Automata
source	International Conference on Generative Art
summary	Cellular automata (CA), like every other dynamical system, can be used to generate music. In fact, starting from any initial state and applying to them simple transition rules, such models are able to produce numerical sequences that can be successively associated to typically musical physical parameters. This approach is interesting because, maintaining fixed the set of rules and varying the initial data, many different, though correlated, numerical sequences can be originated (this recalls the genotype-phenotype dualism). Later on a musification (rendering) process can tie one or more physical parameters typical of music to various mathematical functions: as soon as the generative algorithm produces a numerical sequence this process modifies the physical parameter thus composing a sequence of sounds whose characteristic varies during the course of time. Many so obtained musical sequences can be selected by a genetic algorithm (CA) that promotes their evolution and refinement. The aim of this paper is to illustrate a series of musical pieces generated by CA. In the first part attention is focused on the effects coming from the application of various rendering processes to one dimensional multi state CA; typical behaviours of automata belonging to each of the four families discovered by Wolfram have been studied: CA evolving to a uniform state, CA evolving to a steady cycle, chaotic and complex CA. In order to make this part of the study Musical Dreams, a system for the simulation and musical rendering of one dimensional CA, has been used. In the second phase various CA obtained both by random generation and deriving from those studied in the first part are organised into families and, successively, made evolve through a genetic algorithm. This phase has been accomplished by using Harmony Seeker, a system for the generation of evolutionary music based on GA. The obtained results vary depending on the rendering systems used but, in general, automata belonging to the first family seem more indicated for the production of rhythmical patterns, while elements belonging to the second and fourth family seem to produce better harmonic patterns. Chaotic systems have been seen to produce good results only in presence of simple initial states. Experiments made in the second part have produced good harmonic results starting mainly from CA belonging to the second family.

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	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	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

title	Autopoiesis
source	International Conference on Generative Art
summary	Autopoiesis, is a series of fifteen musical and robotic artificial life sculptures that interact with the public and modify their behaviors based on the both the presence of the participants in the exhibition and the communication between each separate sculpture. Autopoiesis is "self making", a characteristic of all living systems. This characteristic of living systems was defined and refined by Francisco Varella and Humberto Maturana. This series of robotic sculptures talk with each other through a hardwired network and audible telephone tones, which are a musical language for the group. Autopoiesis presents an interactive environment, which is immersive, detailed and able to evolve in real time by utilizing feedback and interaction from audience/participant members. The interactivity engages the viewer/participant who in turn, effects the system's evolution and emergence. This creates a system evolution as well as an overall group sculptural aesthetic.

title	Towards generic representations of designs formalised as features
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Feature-Based Modelling (FBM) is an information modelling technique that allows the formalisation of design concepts and using these formal definitions in design modelling. The dynamic nature of design and design information calls for a specialised approach to FBM that takes into account flexibility and extensibility of Feature Models of designs. Research work in Eindhoven has led to a FBM framework and implementation that can be used to support design.. Feature models of a design process has demonstrated the feasibility of using this information modelling technique. To develop the work on FBM in design, three tracks are initiated: Feature model descriptions of design processes, automated generic representation recognition in graphic representations, and Feature models of generic representations. The paper shows the status of the work in the first two tracks, and present the results of the research work.

title	Java collaborative interface for architectural simulations A case study on wooden ceilings of Krakow
source	International Conference On Conservation - Krakow 2000, 23-24 November 1998, Krakow, Poland
summary	Concern for the architectural and urban preservation problems has been considerably increasing in the past decades, and with it the necessity to investigate the consequences and opportunities opened for the conservation discipline by the development of computer-based systems. Architectural interventions on historical edifices or in preserved urban fabric face conservationists and architects with specific problems related to the handling and exchange of a variety of historical documents and representations. The recent development of information technologies offers opportunities to favour a better access to such data, as well as means to represent architectural hypothesis or design. Developing applications for the Internet also introduces a greater capacity to exchange experiences or ideas and to invest on low-cost collaborative working platforms. In the field of the architectural heritage, our research addresses two problems: historical data and documentation of the edifice, methods of representation (knowledge modelling and visualisation) of the edifice. This research is connected with the ARKIW POLONIUM co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France) and the Institute HAiKZ of Kraków's Faculty of Architecture. The ARKIW programme deals with questions related to the use of information technologies in the recording, protection and studying of the architectural heritage. Case studies are chosen in order to experience and validate a technical platform dedicated to the formalisation and exchange of knowledge related to the architectural heritage (architectural data management, representation and simulation tools, survey methods, ...). A special focus is put on the evolution of the urban fabric and on the simulation of reconstructional hypothesis. Our contribution will introduce current ARKIW internet applications and experiences: The ARPENTEUR architectural survey experiment on Wie¿a Ratuszowa (a photogrammetrical survey based on an architectural model). A Gothic and Renaissance reconstruction of the Ratusz Krakowski using a commercial modelisation and animation software (MAYA). The SOL on line documentation interface for Kraków's Rynek G_ówny. Internet analytical approach in the presentation of morphological informations about Kraków's Kramy Bogate Rynku Krakowskiego. Object-Orientation approach in the modelling of the architectural corpus. The VALIDEUR and HUBLOT Virtual Reality modellers for the simulation and representation of reconstructional hypothesis and corpus analysis.

summary	San Juan city was almost completely destroyed by an earthquake in 1944. The present work intends to show a series of readings about urban space of the pre 44 city. Our purpose is to find out the variation of its qualities at different levels of formatization of the spaces; and the tales of constants that could be operating in the symbolic construction of the city, by the inhabitant’s mental representations. To describe the missing city, to rebuild it as a digital patrimony in order to understand its identity features, means to search for into its history , qualities and uses of its places and shapes. With a new video which resumes the results of the digital reconstruction of the city, the present research intends to share our questions about the ruptures and mutations at the urban level in order to build a possible answer from the urban virtuality.

doi	https://doi.org/10.52842/conf.ecaade.2000.177
summary	Web sites with animations, panoramic images, sound, and virtual reality can provide a strong sense of place, richer than text and photographs and more interactive than cinema. Constructing these sites demands a great deal of visual and textual information, which must be organized, integrated, and coded for delivery. Existing authoring packages are general-purpose, not specifically for architectural applications, and require technical sophistication. In our process for building Place Based Web Resources (PBWRs), after assembling photographic, drawing, text, and audio resources, the author follows a straightforward series of steps. The Hagia Sophia Web Resource resulted from this process; it includes panoramic pictures, photographs and interpretive text about the building and a VRML model.

title	The Importance of Being Abstract: An Indian Approach to Models

summary	Traditional Indian way of life is surrounded by ambiguity. This is in direct contrast to an Aristotelian approach, where polarised stands are always taken. A black and white approach tends to yield results speedily, but exhaustive solutions which can explain complexity are usually brute force procedures. Even so, their conclusions in the end are still suspect. The author believes that rich solutions may exist when we use an 'alternate' or abstract synthesized reality to do our modelling instead of relying on analogies and other direct links to the real world. Models that allow synthesis tend to accept ambiguity. The author presents in this paper an 'unconventional' system to represent architecture which has had some amount of success probably because it started of, on pure abstract grounds that allowed ambiguity instead of basing it on an Aristotelian, analytical model.

title	COMPUTER-MEDIATED COMMUNICATION IN DESIGN
source	PhD Thesis, Faculty of Architecture, University of Sydney
summary	Up till now, architects collaborating with other colleagues did so mostly face-to-face (FTF). They had to be in the same space (co-located) at the same time. Communication was ‘spontaneous’ and ideas were represented, whether verbal or nonverbal, by talking and using ‘traditional drawing tools’. If they were geographically displaced, the interaction was then space affected as well as the probability of being time affected. In this case communication was usually mediated through the telephone, and graphically represented ideas were sent by Fax or posted documents. Recently, some architectural firms started using modems and Internet connections to exchange information, by transferring CAD drawings as well as design information, through e-mail and file transfer protocol (FTP). Discussing ideas in architecture, as a more abstract notion, is different from discussing other more concrete arguments using video conferencing. It is more important to ‘see’ what is being discussed at hand than ‘watch’ the other person(s) involved in the discussion. In other words the data being conveyed might be of more importance than the mode of communication. Taking into consideration recent developments in computer and communication technologies this thesis investigates different communication channels utilised in architectural collaboration through Computer Mediated Collaborative Design (CMCD) sessions as opposed to FTF sessions. This thesis investigates the possible effects these different channels have on collaborative design in general and collaborative design communication in particular. We argue that successful CMCD does not necessarily mean emulating close proximity environments. Excluding certain communication channels in a CMCD environment might affect the flow and quantity of synchronous collaborative communication, but not necessarily the quality and content of mutually communicated and represented design ideas. Therefore different communication channels might affect the type of communication and not necessarily the content of the communication. We propose that audio and video are not essential communication channels in CMCD environments. We posit that architects will collaborate and communicate design representations effectively although with some differences, since those two channels might cause interruptions and successful collaborative sessions can take place without them. For this purpose we conducted twenty-four one-hour experiments involving final year architecture students all working to the same design brief. The experiments were divided into three categories, FTF, full computer mediated collaborative design sessions (CMCD-a; audio-video conferencing plus whiteboard as a shared drawing space) and limited computer mediated collaborative design sessions (CMCD-b; with Lambda MOO used as a chat medium plus whiteboard as a shared drawing space). The experiments were video and audio taped, transcribed and coded into a custom developed coding scheme. The results of the analysed coded data and observations of the videotapes provided evidence that there were noticeable differences between the three categories. There was more design communication and less communication control in the CMCD-b category compared to the FTF and CMCD-a categories. Verbal communication became shorter and straight to the point in CMCD-b as opposed to spontaneous non-stop chat in the other two categories. Moreover in CMCD-b the subjects were observed to be more reflective as well as choosing and re-examining their words to explain ideas to their partners. At times they were seen scrolling back through the text of the conversation in order to re-analyse or interpret the design ideas at hand. This was impossible in FTF and CMCD-a sessions, since the subjects were more spontaneous and audio representations were lost as soon as they were uttered. Also the video channel in the CMCD-a category was ignored and hardly used except for the first few minutes of the experiments, for a brief exchange of light humour on the appearance of each subject. The results obtained from analysing the experiments helped us conclude that different communication channels produce different collaborative environments. The three categories of communication for architectural collaboration explored in our experiments are indicative of the alternatives available to architects now. What is not clear to architects is why they would choose one category over another. We propose that each category has its own strengths and difficulties for architectural collaboration, and therefore should be selected on the basis of the type of communication considered to be most effective for the stage and tasks of the design project.
