summary This paper discusses new approaches to the relation between handmade and computer aided media in design. The discussion focuses on two advanced studio projects in which graduate student designers incorporated interactions between physical models, a digital scanner, handmade drawings, and the manipulation of images in the computer. These interactions provide a valuable supplement to traditional means -- both manual and digital -- for generating, developing, and representing architectural form. Features of the student’s work that other designers will find significant are its focus on multiple interactions, its setting within a realistic design process, and its use of low levels of computer technology. After describing details of the designer’s media techniques, the paper discusses the practical and theoretical implications of the work.

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.

summary The papers collected in this volume reflect not only the conference theme of enabling, capturing, and sharing design ideas, but also the ACADIA’s fifteen-year-old spirit of sharing new ideas about the application and integration of computing technology in architectural education and practice. In the fifteen years of its existence, ACADIA has not only encouraged new research, but has also motivated classroom use of new approaches that incorporate digital media directly into the design process. This educational mission is particularly important as architectural computing spreads from school's design studios into architectural offices, as students whom we train move into the work place and share their knowledge of the new design technologies. The papers in this volume clearly show that the capturing, enabling, and sharing of ideas are enhanced by the use of computers in design, not just in documentation and production, but more importantly from the very origination of the idea. The long sought synergy between the "digital" and the "traditional" is slowly, but increasingly happening in design studios and offices. Thousands of students and architects are exploring design ideas using digital technology, i.e., CAD is more or less in everyone's hands.

summary The general aim of our discussion is to analyze what has been changed in design process according to introducing the computers technology. For the better understanding of the design process evolution, we should precisely define start point - the traditional design process.Let's treat it as an iteration game between a designer and user. If we assume that the designing base is a reductive strategy, we can define six stages of it: 1.) To define a need; 2.) To formulate a task; 3.) To synthesize a design proposals; 4.) To analyze and optimize; 5.) To make a presentation. // The last stage - the presentation of designing proposals is the main factor of using computers in design process and creating definition of CAD as Computer Aided Drafting. According to this interpretation CAD has included four groups of activities: A.) Geometrical modelling; B.) Analysis; C.) Revision and estimation of design proposals; D.) Technical drawing preparing. // Unfortunately it has no connections with another meaning of CAD - Computer Aided Design because concerns every stage of design process except of creation of architectural form. On the other hand, computer enables us to improve the design process by permanent perception of designing forms and dynamic control over the transforming structure. Nowadays thanks to full-function sketching workstation and software like Fractal Design Painter a computer can be useful from the moment when the first line is drawing. It is possible, that the new generation of CAD software - CAD with Personality which connects computer models with picture transformation will enable CAD to be Computer Aided Design.

title Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

doi https://doi.org/10.52842/conf.ecaade.1995.417
summary The purpose of this paper is to analyze the role of simulation in architectural design. The concept of simulation is taken over from physics, where analytical relationships are set up between measured phenomena and mathematical models. Computer visualization applies quantitative models to physical phenomena to simulate analytical aspects, and offers to the designer programs to evaluate, in CAD models, the visual qualities and the numerical quantities of the interactions between shape, light, color and material. Regarding the light-matter simulation, the paper presents recent developments in geometry which make it possible to visualize not only the surface appearance but also the in depth structure of building materials.

title Linking the Virtual to Reality: CAD & Physical Modeling
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 303-311
summary Using both study models and digital models for schematic design allows us to take advantage of the strengths of each. Models constructed manually benefit from spontaneous juxtapositions and serendipitous interactions with light and gravity. Converting these models into the digital realm allows the computer to take over in areas that it does best: geometric transformation, rigorous analysis, elaboration and co-ordination of details and complexity. As a project develops, CAD/CAM methods can generate forms or components for verifying the virtual representation. The paradigm of porting data to appropriate software tools needs to be extended to exporting out of and into the physical realm. Connecting to models in real space allows us to use senses that are not yet completely addressed by digital models.

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 AN EVOLUTIONARY ARCHITECTURE
source London: Architectural Association
summary In "An Evolutionary Architecture", John Frazer presents an overview of his work for the past 30 years. Attempting to develop a theoretical basis for architecture using analogies with nature's processes of evolution and morphogenesis. Frazer's vision of the future of architecture is to construct organic buildings. Thermodynamically open systems which are more environmentally aware and sustainable physically, sociologically and economically. The range of topics which Frazer discusses is a good illustration of the breadth and depth of the evolutionary design problem. Environmental Modelling One of the first topics dealt with is the importance of environmental modelling within the design process. Frazer shows how environmental modelling is often misused or misinterpreted by architects with particular reference to solar modelling. From the discussion given it would seem that simplifications of the environmental models is the prime culprit resulting in misinterpretation and misuse. The simplifications are understandable given the amount of information needed for accurate modelling. By simplifying the model of the environmental conditions the architect is able to make informed judgments within reasonable amounts of time and effort. Unfortunately the simplications result in errors which compound and cause the resulting structures to fall short of their anticipated performance. Frazer obviously believes that the computer can be a great aid in the harnessing of environmental modelling data, providing that the same simplifying assumptions are not made and that better models and interfaces are possible. Physical Modelling Physical modelling has played an important role in Frazer's research. Leading to the construction of several novel machine readable interactive models, ranging from lego-like building blocks to beermat cellular automata and wall partitioning systems. Ultimately this line of research has led to the Universal Constructor and the Universal Interactor. The Universal Constructor The Universal Constructor features on the cover of the book. It consists of a base plug-board, called the "landscape", on top of which "smart" blocks, or cells, can be stacked vertically. The cells are individually identified and can communicate with neighbours above and below. Cells communicate with users through a bank of LEDs displaying the current state of the cell. The whole structure is machine readable and so can be interpreted by a computer. The computer can interpret the states of the cells as either colour or geometrical transformations allowing a wide range of possible interpretations. The user interacts with the computer display through direct manipulation of the cells. The computer can communicate and even direct the actions of the user through feedback with the cells to display various states. The direct manipulation of the cells encourages experimentation by the user and demonstrates basic concepts of the system. The Universal Interactor The Universal Interactor is a whole series of experimental projects investigating novel input and output devices. All of the devices speak a common binary language and so can communicate through a mediating central hub. The result is that input, from say a body-suit, can be used to drive the out of a sound system or vice versa. The Universal Interactor opens up many possibilities for expression when using a CAD system that may at first seem very strange.However, some of these feedback systems may prove superior in the hands of skilled technicians than more standard devices. Imagine how a musician might be able to devise structures by playing melodies which express the character. Of course the interpretation of input in this form poses a difficult problem which will take a great deal of research to achieve. The Universal Interactor has been used to provide environmental feedback to affect the development of evolving genetic codes. The feedback given by the Universal Interactor has been used to guide selection of individuals from a population. Adaptive Computing Frazer completes his introduction to the range of tools used in his research by giving a brief tour of adaptive computing techniques. Covering topics including cellular automata, genetic algorithms, classifier systems and artificial evolution. Cellular Automata As previously mentioned Frazer has done some work using cellular automata in both physical and simulated environments. Frazer discusses how surprisingly complex behaviour can result from the simple local rules executed by cellular automata. Cellular automata are also capable of computation, in fact able to perform any computation possible by a finite state machine. Note that this does not mean that cellular automata are capable of any general computation as this would require the construction of a Turing machine which is beyond the capabilities of a finite state machine. Genetic Algorithms Genetic algorithms were first presented by Holland and since have become a important tool for many researchers in various areas.Originally developed for problem-solving and optimization problems with clearly stated criteria and goals. Frazer fails to mention one of the most important differences between genetic algorithms and other adaptive problem-solving techniques, ie. neural networks. Genetic algorithms have the advantage that criteria can be clearly stated and controlled within the fitness function. The learning by example which neural networks rely upon does not afford this level of control over what is to be learned. Classifier Systems Holland went on to develop genetic algorithms into classifier systems. Classifier systems are more focussed upon the problem of learning appropriate responses to stimuli, than searching for solutions to problems. Classifier systems receive information from the environment and respond according to rules, or classifiers. Successful classifiers are rewarded, creating a reinforcement learning environment. Obviously, the mapping between classifier systems and the cybernetic view of organisms sensing, processing and responding to environmental stimuli is strong. It would seem that a central process similar to a classifier system would be appropriate at the core of an organic building. Learning appropriate responses to environmental conditions over time. Artificial Evolution Artificial evolution traces it's roots back to the Biomorph program which was described by Dawkins in his book "The Blind Watchmaker". Essentially, artificial evolution requires that a user supplements the standard fitness function in genetic algorithms to guide evolution. The user may provide selection pressures which are unquantifiable in a stated problem and thus provide a means for dealing ill-defined criteria. Frazer notes that solving problems with ill-defined criteria using artificial evolution seriously limits the scope of problems that can be tackled. The reliance upon user interaction in artificial evolution reduces the practical size of populations and the duration of evolutionary runs. Coding Schemes Frazer goes on to discuss the encoding of architectural designs and their subsequent evolution. Introducing two major systems, the Reptile system and the Universal State Space Modeller. Blueprint vs. Recipe Frazer points out the inadequacies of using standard "blueprint" design techniques in developing organic structures. Using a "recipe" to describe the process of constructing a building is presented as an alternative. Recipes for construction are discussed with reference to the analogous process description given by DNA to construct an organism. The Reptile System The Reptile System is an ingenious construction set capable of producing a wide range of structures using just two simple components. Frazer saw the advantages of this system for rule-based and evolutionary systems in the compactness of structure descriptions. Compactness was essential for the early computational work when computer memory and storage space was scarce. However, compact representations such as those described form very rugged fitness landscapes which are not well suited to evolutionary search techniques. Structures are created from an initial "seed" or minimal construction, for example a compact spherical structure. The seed is then manipulated using a series of processes or transformations, for example stretching, shearing or bending. The structure would grow according to the transformations applied to it. Obviously, the transformations could be a predetermined sequence of actions which would always yield the same final structure given the same initial seed. Alternatively, the series of transformations applied could be environmentally sensitive resulting in forms which were also sensitive to their location. The idea of taking a geometrical form as a seed and transforming it using a series of processes to create complex structures is similar in many ways to the early work of Latham creating large morphological charts. Latham went on to develop his ideas into the "Mutator" system which he used to create organic artworks. Generalising the Reptile System Frazer has proposed a generalised version of the Reptile System to tackle more realistic building problems. Generating the seed or minimal configuration from design requirements automatically. From this starting point (or set of starting points) solutions could be evolved using artificial evolution. Quantifiable and specific aspects of the design brief define the formal criteria which are used as a standard fitness function. Non-quantifiable criteria, including aesthetic judgments, are evaluated by the user. The proposed system would be able to learn successful strategies for satisfying both formal and user criteria. In doing so the system would become a personalised tool of the designer. A personal assistant which would be able to anticipate aesthetic judgements and other criteria by employing previously successful strategies. Ultimately, this is a similar concept to Negroponte's "Architecture Machine" which he proposed would be computer system so personalised so as to be almost unusable by other people. The Universal State Space Modeller The Universal State Space Modeller is the basis of Frazer's current work. It is a system which can be used to model any structure, hence the universal claim in it's title. The datastructure underlying the modeller is a state space of scaleless logical points, called motes. Motes are arranged in a close-packing sphere arrangement, which makes each one equidistant from it's twelve neighbours. Any point can be broken down into a self-similar tetrahedral structure of logical points. Giving the state space a fractal nature which allows modelling at many different levels at once. Each mote can be thought of as analogous to a cell in a biological organism. Every mote carries a copy of the architectural genetic code in the same way that each cell within a organism carries a copy of it's DNA. The genetic code of a mote is stored as a sequence of binary "morons" which are grouped together into spatial configurations which are interpreted as the state of the mote. The developmental process begins with a seed. The seed develops through cellular duplication according to the rules of the genetic code. In the beginning the seed develops mainly in response to the internal genetic code, but as the development progresses the environment plays a greater role. Cells communicate by passing messages to their immediate twelve neighbours. However, it can send messages directed at remote cells, without knowledge of it's spatial relationship. During the development cells take on specialised functions, including environmental sensors or producers of raw materials. The resulting system is process driven, without presupposing the existence of a construction set to use. The datastructure can be interpreted in many ways to derive various phenotypes. The resulting structure is a by-product of the cellular activity during development and in response to the environment. As such the resulting structures have much in common with living organisms which are also the emergent result or by-product of local cellular activity. Primordial Architectural Soups To conclude, Frazer presents some of the most recent work done, evolving fundamental structures using limited raw materials, an initial seed and massive feedback. Frazer proposes to go further and do away with the need for initial seed and start with a primordial soup of basic architectural concepts. The research is attempting to evolve the starting conditions and evolutionary processes without any preconditions. Is there enough time to evolve a complex system from the basic building blocks which Frazer proposes? The computational complexity of the task being embarked upon is not discussed. There is an implicit assumption that the "superb tactics" of natural selection are enough to cut through the complexity of the task. However, Kauffman has shown how self-organisation plays a major role in the early development of replicating systems which we may call alive. Natural selection requires a solid basis upon which it can act. Is the primordial soup which Frazer proposes of the correct constitution to support self-organisation? Kauffman suggests that one of the most important attributes of a primordial soup to be capable of self-organisation is the need for a complex network of catalysts and the controlling mechanisms to stop the reactions from going supracritical. Can such a network be provided of primitive architectural concepts? What does it mean to have a catalyst in this domain? Conclusion Frazer shows some interesting work both in the areas of evolutionary design and self-organising systems. It is obvious from his work that he sympathizes with the opinions put forward by Kauffman that the order found in living organisms comes from both external evolutionary pressure and internal self-organisation. His final remarks underly this by paraphrasing the words of Kauffman, that life is always to found on the edge of chaos. By the "edge of chaos" Kauffman is referring to the area within the ordered regime of a system close to the "phase transition" to chaotic behaviour. Unfortunately, Frazer does not demonstrate that the systems he has presented have the necessary qualities to derive useful order at the edge of chaos. He does not demonstrate, as Kauffman does repeatedly, that there exists a "phase transition" between ordered and chaotic regimes of his systems. He also does not make any studies of the relationship of useful forms generated by his work to phase transition regions of his systems should they exist. If we are to find an organic architecture, in more than name alone, it is surely to reside close to the phase transition of the construction system of which is it built. Only there, if we are to believe Kauffman, are we to find useful order together with environmentally sensitive and thermodynamically open systems which can approach the utility of living organisms.

summary The integration of state-of-the-art photogrammetric methods with the capabilities of CAAD has great potential for a variety of architectural applications. This paper describes the current status of an ongoing research project which aims to develop an easy to use tool for the photogrammetric generation of accurate, reliable and well structured 3D CAAD models of architectural objects. The project adresses the whole range of issues that arise from the digital image acquisition to the data processing, the data integration between photogrammetry and CAAD and the architectural structuring of the geometric data. While also giving a brief overview of the project, the paper concentrates on one central aspect of the system: a method to model what we will define as "weak forms" as the basis for qualitatively controlled computer measurement.

summary Product Modeling is considered to be an established concept not only for semantically based data exchange, but also for the specification of models, dealing with specific application requirements. The product model approach is regarded to be one step towards a new generation of Computer Aided Architectural Design, and to provide underlying means for enabling communication between different applications on a semantic level. After on overview about the background and the basis principles of product modeling, the authors discuss how product models can be used in commercial developments and in applied research projects.

title SIMULATION - HOW DOES IT SHAPE THE MESSAGE?
source The Future of Endoscopy [Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4], pp. 47-54
summary Architectural simulation techniques - CAD, video montage, endoscopy, full-scale or smaller models, stereoscopy, holography etc. - are common visualizations in planning. A subjective theory of planners says "experts are able to distinguish between 'pure design' in their heads and visualized design details and contexts like color, texture, material, brightness, eye level or perspective." If this is right, simulation details should be compensated mentally by trained people, but act as distractors to the lay mind.

Environmental psychologists specializing in architectural psychology offer "user needs' assessments" and "post occupancy evaluations" to facilitate communication between users and experts. To compare the efficiency of building descriptions, building walkthroughs, regular plans, simulation, and direct, long-time exposition, evaluation has to be evaluated.

Computer visualizations and virtual realities grow more important, but studies on the effects of simulation techniques upon experts and users are rare. As a contribution to the field of architectural simulation, an expert - user comparison of CAD versus endoscopy/model simulations of a Vienna city project was realized in 1995. The Department for Spatial Simulation at the Vienna University of Technology provided diaslides of the planned city development at Aspern showing a) CAD and b) endoscopy photos of small-scale polystyrol models. In an experimental design, they were presented uncommented as images of "PROJECT A" versus "PROJECT B" to student groups of architects and non-architects at Vienna and Salzburg (n= 95) and assessed by semantic differentials. Two contradictory hypotheses were tested: 1. The "selective framing hypothesis" (SFH) as the subjective theory of planners, postulating different judgement effects (measured by item means of the semantic differential) through selective attention of the planners versus material- and context-bound perception of the untrained users. 2. The "general framing hypothesis" (GFH) postulates typical framing and distraction effects of all simulation techniques affecting experts as well as non-experts.

The experiment showed that -counter-intuitive to expert opinions- framing and distraction were prominent both for experts and lay people (= GFH). A position effect (assessment interaction of CAD and endoscopy) was present with experts and non-experts, too. With empirical evidence for "the medium is the message", a more cautious attitude has to be adopted towards simulation products as powerful framing (i.e. perception- and opinion-shaping) devices.

title Beyond the Adversial: Conflict Resolution, Simulation and Community Design
source The Future of Endoscopy [Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4]
summary Fundamentally, the design of communities in the United States is grounded in the Constitution’s evolving definition of property and the rights and obligations attendant to the ownership and use of real property. The rearticulation of Jefferson’s dictum in the Declaration of Independence; “that individuals have certain inalienable rights, among these are life, liberty, and the pursuit of happiness” to the Constitution’s “life, liberty and property” represents a pragmatic understanding of the relationship between property and the actualization of the individual in society. In terms of community design, this means extensive public involvement and participation in not only the formulation of rules and regulations but of individual projects as well.

Since the 1960’s as planning and community design decision making has become increasingly contentious, the American legal system’s adversial approach to conflict resolution has become the dominant model for public decision making. The legal system’s adversial approach to adjudication is essentially a zero-sum game of winners and losers, and as most land-use lawyers will agree, is not a good model for the design of cities. While the adversial approach does not resolve disputes it rarely creates a positive and constructive consensus for change. Because physical planning and community design issues are not only value based, community design through consensus building has emerged as a new paradigm for physical planning and design.

The Environmental Simulation Center employs a broad range of complementary simulation and visualization techniques including 3-D vector based computer models, endoscopy, and verifiable digital photomontages to provide objective and verifiable information for projects and regulations under study.

In this context, a number of recent projects will be discussed which have explored the use of various simulation and visualization techniques in community design. Among them are projects involved with changes in the City’s Zoning Regulations, the community design of a major public open space in one of the region’s mid-size cities, and the design of a new village center for a suburban community, with the last project employing the Center’s userfriendly and interactive 3-D computer kit of parts. The kit - a kind of computer “pattern book” is comprised of site planning, urban and landscape design and architectural conventions - is part of the Center’s continuing effort to support a consensus based, rather than adversial based, public planning and design process.

title ID'EST: An Integrated Modelling Framework for Management of Architectural Data
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 377-387
summary An Integrated Design Environment, IDE, facilitates cooperation between different disciplines. The paper investigates the data modelling framework, distinguishes between homogeneous and heterogeneous model worlds, discusses the formal mapping mechanisms available to establish a heterogeneous model world, and introduces a way to incorporate CAD systems into IDE A prototype IDE has been developed to prove these methods. The ID'EST prototype comprises its own core data model, different schemas to cope with several design views, and interfaces to incorporate external CAD systems. A prototype architectural data model has been defined, that includes core data models and aspect models for enclosure system and spatial system. Conventional CAD systems can be integrated into ID'EST, if they are able to map data from the aspect models into their own data structure, and vice versa, on a high semantic level. The inherent methods of classifying data in CAD, layers, macros and attached attributes, have been used to retrieve product data from CAD data files. The usability of conventional CAD systems as data instantiation tools for IDE has been proved and a path has been shown, by which existing tools can be integrated into new technology solutions.

title A history and application of visual simulation in which perceptual behaviour movement is measured.
source Architectural and Urban Simulation Techniques in Research and Education [3rd EAEA-Conference Proceedings]
summary For our research on perception and judgment, we have developed a new visual simulation system based on the previous system. Here, we report on the development history of our system and on the current research employing it. In 1975, the first visual simulation system was introduced, witch comprised a fiberscope and small-scale models. By manipulating the fiberscope's handles, the subject was able to view the models at eye level. When the pen-size CCD TV camera came out, we immediately embraced it, incorporating it into a computer controlled visual simulation system in 1988. It comprises four elements: operation input, drive control, model shooting, and presentation. This system was easy to operate, and the subject gained an omnidirectional, eye-level image as though walking through the model. In 1995, we began developing a new visual system. We wanted to relate the scale model image directly to perceptual behavior, to make natural background images, and to record human feelings in a non-verbal method. Restructuring the above four elements to meet our equirements and adding two more (background shooting and emotion spectrum analysis), we inally completed the new simulation system in 1996. We are employing this system in streetscape research. Using the emotion spectrum system, we are able to record brain waves. Quantifying the visual effects through these waves, we are analyzing the relation between visual effects and physical elements. Thus, we are presented with a new aspect to study: the relationship between brain waves and changes in the physical environment. We will be studying the relation of brain waves in our sequential analysis of the streetscape.

title Integration of Digital Photogrammetry and CAAD: Constraint-Based Modelling and Semi-Automatic Measurement
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 35-47
summary The integration of state-of-the-art photogrammetric methods with the capabilities of CAAD has great potential for a variety of architectural applications. This paper describes the current status of an ongoing research project which aims to develop an easy to use tool for the photogrammetric generation of accurate, reliable and well structured 3D CAAD models of architectural objects. The system essentially consists of a standard CAAD package to which additional functionality was added and a Digital Photogrammetry Station (DIPS), providing semi-automatic computer measurement. The paper concentrates on two main issues in the design of the system: the data-integration and the CAAD-based 3D feature extraction. The data-integration is achieved using a knowledge-base. On top of an adequate data-transfer between the two systems this knowledge-base enables constraint-based modelling in CAAD and qualitatively controlled measurement in DIPS. In the section about Digital Photogrammetry we describe the 3D feature extraction procedure in detail and point out how the qualitative control can be achieved. A practical example is used to illustrate the performance of the system.

summary The Department of Architecture Warsaw University of Technology was the first in Poland to take part in the third edition of the international student workshop -Virtual Design Studio. This year’s subject is a competition organized by ACSA 2A Center for Cultural and Religious Studies". The design is located on Miyajima Island in the Inland Sea of Japan near Hiroshima. VDS workshops are a proposal to create a new approach to architectural designing - working in joint groups, where the participants are separated by long distances. This idea wouldn't possible without an important tool - the InterNet. The information is sent mainly by E-mail through News Servers made by groups in each country. The News Server works as electronic pinup board where every student can locate his work. The multimedia tool -HyperDoc- permits students to easily and quickly look at other students' work. VDS'95 participants are divided into international groups of 5-7 people, They use almost every method of computer presentation: photorendering, animation, scanned freehand drawings and photos. The basic tool is CAD. Students also use traditional methods of representation like models, sketches, drawings. The Virtual Design Studio is an important experience. It shows a new concept of designing: Computer Mediated Design. The necessary contact between architect and client can be realized by the computer network. The problem of distance is eliminated. Conclusions from VDS activity will permit the creation in the future of a special net of design studios, where all discussions will be accomplished by computer. All over the world the network of Infoways will bring people together.

title Architecture not Aided – Architecture Transformed
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 193-207
summary Permeating of new technologies (computer aided design) into architectural design causes essential changes in its structure. It is the process, set of mutually interrelated different social, political, cultural occurrences, which happen in the present time. Everything what is new, brings either fear or unreliable expectations. The reflection is needed to name what we will have to deal with in architecture. Architecture is not a stable sphere, and as other disciplines is subject to processes of change, which result from the specificity of the time. We need to be aware of the consequences these processes could cause. I located them in six general fields: 1.) Transformation of the tool traditional tools - set of singular, autonomous, mono-functional devices, which together make the environment; computer - one tool consisting of non-autonomous internal and external units, multifunctional; itself it is the environment, system; 2.) Transformation of the medium. As the medium is the message (M.McLuhan), so the essence of media is transmission. Traditional transmission in architectural design is direct (transmission is equivalent to recording, notation), computer based transmission is indirect (transmission is not equivalent to recording); 3.) Transformation of perception, imagination and thinking. Perception - in the process of design directly relates to media Indirect transmission - causes also rupture in direct relation between record and perception (mainly in modelling); simulated object is a stage in the process. Imagination, thinking - influenced with perception, with data transmitted from the medium - can be seen as inspiration; 4.) Transformation of cooperation and communication. It is to be done by elimination of some of intermediate stages in the design process and use of multimedial communication systems (Internet); 5.) Transformation of methodology. Same as in 4 with the possibility of simultaneous shifting in the hierarchy of design stages - almost full reversal of the process possible (regardless of individual methodology) - if needed of course; 6. Transformation of architecture itself. This concerns very deeply point 3 - and it rooms that natural consequences of the changes in perception, imagination and thinking should result in the new understanding of architecture - not as electronic methaphone, but as a sphere relevant (?!) to the vision of the world, which, as we see, is dramatically changing. The basic issue to accept is that this vision of the world should be interpreted individually. Personally.

doi https://doi.org/10.52842/conf.acadia.1996.031
summary This paper reports on a media class offered during the 1995-96 academic year at the University of Oregon. This course, a renovation of an existing 'manual' media offering targeted intermediate Ievel graduate and undergraduate students who, while relatively experienced design students, were relatively inexperienced users of digital media for design. This course maintained a pedagogical emphasis on design process, a point of view that media are powerful influences on design thinking, and an attitude toward experimentation (and reflection) in matters of media and design process. Among the experiments explored were fitting together digital with manual media, and using digital media to collaborate in an electronic workspace. The experience offers opportunity to consider how digital media might be more widely integrated with what remains a predominantly 'manual' design process and media context for many architecture schools and practices.
