summary Given that there is a need to shade a window from the summer sun and also a need to expose it to the winter sun, this article describes an algorithm to design automatically a geometric construct that satisfies both requirements. The construct obtained represents the minimum solution to the simultaneous requirements. The window may be described by an arbitrary convex polygon and it may be oriented in any direction and it may be placed at any chosen latitude. The algorithm consists of two sequential steps: first to find a winter solar funnel surface; and the second to clip the surface subject to the summer shading conditions. The article introduces the design problem, illustrates the results through two examples, outlines the logic of the algorithm and includes the derivation of the mathematical relations required to implement the algorithm. This work is part of the MUSES project, which is a long term research effort to integrate Energy Consciousness with Computer Graphics in Architectural 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.

title Progeny: A Grasshopper Plug-in that Augments Cellular Automata Algorithms for 3D Form Explorations

summary Cellular automata (CA) is a well-known computation method introduced by John von Neumann and Stanislaw Ulam in the 1940s. Since then, it has been studied in various fields such as computer science, biology, physics, chemistry, and art. The Classic CA algorithm is a calculation of a grid of cells' binary states based on neighboring cells and a set of rules. With the variation of these parameters, the CA algorithm has evolved into alternative versions such as 3D CA, Multiple neighborhood CA, Multiple rules CA, and Stochastic CA (Url-1). As a rule-based generative algorithm, CA has been used as a bottom-up design approach in the architectural design process in the search for form (Frazer,1995; Dinçer et al., 2014), in simulating the displacement of individuals in space, and in revealing complex relations at the urban scale (Güzelci, 2013). There are implementations of CA tools in 3D design software for designers as additional scripts or plug-ins. However, these often have limited ability to create customized CA algorithms by the designer. This study aims to create a customizable framework for 3D CA algorithms to be used in 3D form explorations by designers. Grasshopper3D, which is a visual scripting environment in Rhinoceros 3D, is used to implement the framework. The main difference between this work and the current Grasshopper3D plug-ins for CA simulation is the customizability and the real-time control of the framework. The parameters that allow the CA algorithm to be customized are; the initial state of the 3D grid, neighborhood conditions, cell states and rules. CA algorithms are created for each customizable parameter using the framework. Those algorithms are evaluated based on the ability to generate form. A voxel-based approach is used to generate geometry from the points created by the 3D cellular automata. In future, forms generated using this framework can be used as a form generating tool for digital environments.

title Shading Mask: A Teaching Tool for Sun Shading Devices
doi https://doi.org/10.52842/conf.acadia.1995.243
source Computing in Design - Enabling, Capturing and Sharing Ideas [ACADIA Conference Proceedings / ISBN 1-880250-04-7] University of Washington (Seattle, Washington / USA) October 19-22, 1995, pp. 243-251
summary Sun shading devices, either as parts of a building or separately placed from a building facade, affect natural lighting and ventilation, solar gain, and overall building performance. The role of sun shading devices or solar radiation control systems is taught at every school of architecture. Yet, only a few architecture students, architects, and designers have applied them to reduce glare, control light intensity, radiation, and minimize cooling load on their projects. Using a well-designed computer program to teach, and re-teach when necessary, the use of sun shading devices is more understandable, clear, and interesting than reading a book on the same topic. Having a readily available tool would also encourage architects and designers to use the shading devices as a method of conserving energy and lowering operating cost in the buildings that they design. Visual Basic 3.0 was chosen as the development language for this Windows-based program. SHADING MASK uses Edward Mazria's rectangular sun path diagrams as a basis. The program explains basic theory of solar control; generates sun path diagrams; allows the design of overhead, side, and eggcrate shading devices; calculates solar angles and shading masks; and provides case studies of actual buildings.

summary The rapid development of the potentialities of multimedia imposes a reflection about its use in teaching architecture. Multimedia is multifaceted and each facet deserves a particular attention inasmuch as it can change the traditional approach to learning. A direct experience of an architectural work can be simulated with a impact far stronger than an experience trough photographs, drawings and books can do. But, as every positive fact can have in certain cases also some negative consequences. the intensity of the participation to an experience structured by someone else can leave less space to a personal approach to the object of the presentation. The same problem is posed if we consider the structure of an hypertext. The essence of the hypertext lies in the net of relationships between very different kinds of documents that it is able to manage in order to express the complexity of its theme. But who has to create the net, the teacher choosing the relationship that he thinks important or the learner to build a personal image of the hypertext matter. It is an old question about the two faces of teaching: transmitting knowledge or giving the learner the instruments to build by oneself his store of knowledge. Easy and trivial answer that both approaches can be useful. The accomplishment of a multimedial sequence of average complexity requires at present a lot of time. Hence, to be convenient, it is to be used many times, then by many students. The effectiveness of the tool partly depends on the rapidity with which it can be constructed. Speeding it up would allow to use this kind of tools with the same easiness than mare traditional means of representation. Besides those general considerations a check is to do on the peculiarities, if any, of the use of multimedia in the different disciplines of the formative curriculum of an architect. This is theme of our thirteenth conference. The programme has been articulated into sessions, dealing separately with history teaching, design teaching and research. Of course the sessions dealing with design are more numerous than the other, since design is the axis of teaching architecture. The presented paper cover a large arc of arguments, dealing with many facets of the proposed themes with plenty of examples and documentation on practical experiences. constituting a corpus of great usefulness for any operator in the field of architectural teaching.

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.

title Incorporation of Natural Language Processing and a Generative System - An Interactive System that Constructs Topological Models from Spatial Descriptions in Natural Language
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 205-218
summary The natural language processing technique and the spatial reasoning technique are incorporated to create a computational model representing the process of updating and maintaining the knowledge about spatial relations. An algorithm for the spatial reasoning is proposed. An interactive system that understands sentences describing spatial relations is implemented. The system determines the reference of an anaphoric or deictic expression from the literal meaning of the input and the implicit meaning derived from the literal meaning. The consistency of the spatial relations is maintained. The correct topological representations of the spatial relations are generated from well-formed descriptions.

title Communication of Ideas in Architecture Versus Computer Techniques
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 171-180
summary Computer as a tool in architects' work is an obvious thing for near all of us. Recent two - three years have shown that probably the most revolutionary feature of computers is their immense possibility of usage in today's communication techniques, the continuous flow of information. This fact makes us to think about computer techniques as an useful tool not only in designing, but also in extensive presenting of ideas - like communication between architects and all the others involved in the designing and building process. Presenting ideas requires prior process of gathering data and storing it in computers' memory. Incredible progress in ways of organizing information leads also to the idea of developing a sketch of a standard of the amount and structure of information gathered to make it an universal set of parameters describing the design - a multi - functional database. The first part (presenting ideas) is more to be used in Poland by now. Architects should appreciate benefits of an impressive presentation and they already started to. The universal database for use by everyone, or rather a file of the project, which presentation is a part of, is rather a theory by now. But exploring it’s potential and a real need to create one - is essential.

summary We have been exploiting the capabilities of multimedia tools to combine visual and audio images to create a multilingual reference tool for architecture students. 0ur students work in both Cantonese and English, learning incomplete architectural vocabularies in both languages. We set out to create a tool which can be used by student’s as a reference tool as well as a teaching tool. In response to this need, we have created a multimedia lexicon using three-dimensional models of buildings with which the user can interact, identify elements and hear and see the correct term for the elements identified in the language of their choice. The system can handle any number of language combinations or building models. This paper describes a system currently under development which has gone through two iterations to explore the issues involved.

title A Tool for Conceptual Design Evaluation Based on Compliance with Supplementary Planning Guidance and Local Planning Policies
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The need has been established for a computer based decision support tool to use during the conceptual stages of architectural design. The main functions are being designed in order to check design compliance with the requirements of local planning authorities; with regards to building size, height, plot ratios, circulation and accessibility, and the preservation of natural features on site. The measures to determine proper evaluation will be based upon site-development briefs, and design guides produced by the local planning authorities. This tool is being developed to operate under AutoCAD environment; the construction industry standard computer aided design software, following standard layering convention, integrated command lines, and pull-down menus. It will also provide many functions for editing two and three dimensional drawings specifically for the environmental analysis tasks. In addition to the common graphical output of Aut0CAD; i.e. plans, elevations and three dimensional models, the tool will generate textual analysis of the design in report format to use as part of the Environmental Impact Statement of proposed development. The speculative tool's functions will be based upon the result of two types of field studies. First, interviews and questionnaires will be carried out tailor-made for architects and planners of both private and public sectors. These will cover issues related to the performance of Computer Aided Architectural Design applications with regard to the evaluation of design schematics, and decision-making for the production of materials for environmental statements. Second, field observation will be carried out to observe the concerned professionals as decision-makers while assessing building design proposals. A prototype will be designed and then tested against the expectations of the tool designer, then the tool performance will be evaluated by a team of professionals participated in the field studies. A critical analysis of the prototype design methodology and the concluding study findings will be documented as part of a postgraduate research thesis to be completed in June 1995.

summary Existing computer software to support the teaching of environmental issues to architecture students is mainly based on energy calculation methods or packages of information split into subject areas. Neither approach seems to adequately support the early stages of the design process. The paper explores the construction of a model for a computer based learning system to teach the development of environmental strategies. Different strands of educational theory were used to develop teaching principles based around consideration of the subjective quality of knowledge influenced by ideas and theories from different sources, the importance of learning a "language" consisting of methods and theories of a subject and their application in context and the suggestion that "deep" learning requires conceptual changes. A suitable framework for the development of environmental strategies is suggested and its implementation using multi-media software as a method of integrating different types of information and learning materials is proposed. The paper concludes that the process of analysis is a key part of the system and should be made the focus of the structure and contents.

summary Computers have exploded into the world of the architect, yet architects have only begun to explore the role of computers in the creative process or the effects of particular applications on design projects. Likewise, educators are seeking methods for investigating the computer as a tool which may or may not effect the thing produced. Is it a tool for representation (copying), or a key player in the generation of ideas—a tool for the production of form? This paper describes the theoretical foundations and results of a series of exercises developed for beginning design students. In three investigations students consider: Algorithms (the fundamental logic of a computer application) using Building blocks (reductive entities that act as the origins of form) by Collaging and making assemblies (techniques for experimentation and exploration). The purpose of these exercises (called ABC exercises) is to explore the relationship between the computer as a tool and the production of form and type in architecture.

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 StereoCAD: Three Dimensional Representation
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 343-355
summary Concepts of stereoscopic vision have been around for more than two thousand years. Despite this long history, its application to the field to architecture and design seems relatively unexplored. Synthesis of two technologies, the stereoscope and the computer, was the focus of the present study. The goal of the research was to determine if computer-generated stereoscopic pairs hold value for architectural design. Using readily available computer technology (Apple Macintosh) the research team modelled and rendered an existing project to verify the degree of correlation between the physical construct, the computer 3D model and resultant correlation between the physical construct, the computer 3D model and resultant rendered stereo-paired representation. The experiments performed in this study have shown that producing stereo-paired images that highly correlate to reality is possible using technology that is readily available in the marketplace. Both the technology required to produce (i.e., personal computer and modelling/rendering software) and view (i.e., modified stereoscope) the images is unimposing. Both devices can easily fit in a studio or a boardroom and together can be utilized effectively to permit designers, clients and end-users to experience proposed spaces and projects. Furthermore, these technologies are familiar (clients and end-users have already experienced them in other applications and settings) and assume a fraction of the cost of more dynamic, immersive virtual reality systems. Working from this base, limitations of the process as well as future applications of computer-generated stereoscopic images are identified.

source Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 43-52
summary This paper illustrates a research project concerning the analysis of architectural works through a comparative study based on hypermedia tools; by exploring the hypermedia, users can find the main subjects relative to the "method " of architectural planning. The use of multimedia in architecture allows the integration in a single system of different types of information which are necessary for the description of a work. texts, designs, photos and sounds. In addition, the hypertext information structure allows the direct intervention on analyzed projects, by pointing out the more important themes and their relationships. Users have the opportunity to immerse themselves in hypermedia and choose the subject to navigate through on each occasion. Our research project aims at developing a prototype concerning two architects. I.L.Kahn and F.L. Wright. The development methodology is based on the key role played by the components of architectonic works, thus allowing users to compare them in a simple and correct way. The methodology used in this work can be extended to other architects or periods, by simply changing the possibility of navigation, i.e. by changing the reading keys.

summary IPER (hypertext for the knowledge of building patrimony) is the result of a research developed with C.N.R. (National Research Institute). The aim of IPER is to provide the knowledge, the description and the management of one or more historical buildings for public or private institutions. IPER allowed us to improve our methodology of building analysis, covering various disciplinary fields, in two different systems. (1.) the first one, synthetic and suitable for a group of historical buildings, (2.) the second one, complex and particularly made for monumental buildings. // This experience is related to the new regulation of teaching architecture in Italy made in 1993. The main novelty is the introduction of the laboratories with the contemporary presence of two or three teachers of different disciplines, working together with the students on the same project with different approaches. This opportunity allowed us to introduce the "knowledge engineer" as a teacher in the laboratory of building technology. IPER is given to the students with the aim of experimenting and solving the theoretical and practical difficulties that students of different years may encounter in the knowledge and representation of buildings and in the organisation of all the data from the case study.

title On the Conceptual Feasibility of a CAAD-CAAI Integrated Decision Support System: A Computer Aided Environment for Technical Decision Making in Architecture
source Delft University of Technology
summary This document addresses two questions: What are the ultimate means of design support we can offer to the architect, and how can we devise them? We are not the first ones to address these questions, neither the first ones to point our finger in the direction of Decision Support Systems for such purposes. Nevertheless, we may be among those scholars that understanding 'Decision Support" in terms of "Learning Support", are willing to explore the implications that such an understanding assumes for the concept of Decision Support Systems. Our exploration in such regards has shown us that knowledge application and knowledge acquisition cycles describe a continuum, and that such cycles, encapsulated in our "Practice Based Learning" and "Continuing Professional Development" dynamics are present in both our instructional and professional environments. From such a perspective, our scope regarding feasible Decision Support Systems is not restricted to the use of CAAD instrumental resources, but expanded into a context of CAAD-CAAI integration. Throughout this document we conceive a system that blends CAAD and CAAI resources looking forward to the creation of a Support Environment that seeks to motivate a reflective attitude during design, in such a way, upgrade our capability for acquiring as well as applying knowledge in design. In instrumental terms, this document explains how mainstream CAAD developments in the field of "Intelligent Front End Technology" and CAAI developments in the field of "Knowledge-based Curricular Networks" can complement each other in the establishment of a Decision Support System of trans-environmental relevancy. As an application framework for the concept and instrumental base described above, this document presents an image of the kind of decision-making model that it will intend to support, the kind of task support model it will look forward to implement, and the kind of general instrumental layout it will require. On the basis of such an instrumental layout, the system that is hereby outlined can be regarded as a "CAAD-CAAI Integrated", "Intelligent", and "User-Oriented" Interface System.
