title Models of Collaboration for Designers in a Computer Supported Environment
source Formal Aspects of Collaborative CAD, IFIP, pp. 99-108
summary The development of models for Computer Mediated Collaborative Design (CMCD) provides guidelines for the continuing development of technology and tools for CMCD. In order to develop models for CMCD, a range of experiments and research objectives needs to be developed. The current literature around models for CMCD is still quite informal and descriptive. In this paper, we define the roles and types of models for CMCD. We propose a framework for understanding the contribution such models can make that considers two phenomomena in CMCD: communicating and designing. We present some descriptive models from design research, CSCW research, and CMCD research and show how these models address communicating and designing.

title Choosing Tools for a Virtual Community
source Creative Collaboration in Virtual Communities 1997, ed. A. Cicognani. VC'97. Sydney: Key Centre of Design Computing, Department of Architectural and Design Science, University of Sydney, 20 p.
summary This paper reports on the results of experiments carried out to identify the effects of computer-mediated communication between participants involved in a design problem. When setting up a virtual design community, choices must be made between a variety of tools, choices dictated by budget, bandwidth, ability, availability. How do you choose between the tools, which is useful and how will each affect the outcome of the design exchanges you plan? Cognitive modelling methodologies such as GOMS have been used by interface designers to capture the mechanisms of action and interaction involved in routine expert behavior. Using this technique, which breaks down an individual's behaviors into Goals, Operators, Methods, and Selection rules, it is possible to evaluate the impact of different aspects of an interface in task-specific ways. In the present study, the GOMS methodology was used to characterize the interactive behavior of knowledgeable participants as they worked on a design task under different communication-support conditions.

Pairs of participants were set a design problem and asked to solve it in face-to-face settings. The same problem was then tackled by participants in settings using two different modes of computer-supported communication: email and an electronic whiteboard. Protocols were collected and analyzed in terms of the constraints of each tool relative to the task and to each other. The GOMS methodology was used as a way to represent the collaborative design process in a way that yields information on both the productivity and performance of participants in each of the three experimental conditions. It also yielded information on the component elements of the design process, the basic cognitive building-blocks of design, thereby suggesting fundamentally new tools that might be created for interaction in virtual environments.

A further goal of the study was to explore the nature of task differences in relation to alternative platforms for communication. It was hypothesized that design processes involving significant negotiation would be less aided by computer support than straight forward design problems. The latter involve cooperative knowledge application by both participants and are therefore facilitated by information-rich forms of computer support. The former, on the other hand, requires conflict resolution and is inhibited by non face-to-face interaction. The results of this study point to the fact that the success of collaboration in virtual space is not just dependent on the nature of the tools but also on the specific nature of the collaborative task.

title Is Design Really Social
source Creative Collaboration in Virtual Communities 1997, ed. A. Cicognani. VC'97. Sydney: Key Centre of Design Computing, Department of Architectural and Design Science, University of Sydney, 8 p.
summary There are many who will readily agree with Mitchell’s assertion that “the most interesting new directions (for computer-aided design) are suggested by the growing convergence of computation and telecommunication. This allows us to treat designing not just as a technical process... but also as a social process.” [Mitchell 1995]. The assumption is that design was a social process until users of computer-aided design systems were distracted into treating it as a merely technical process. Most readers will assume that this convergence must and will lead to increased communication between design participants; that better social interaction leads to be better design. The unspoken assumption appears to be that putting the participants into an environment with maximal communication channels will result in design collaboration. The tools provided; therefore; must permit the best communication and the best social interaction. We think it essential to examine the foundations and assumptions on which software and environments are designed to support collaborative design communication. Of particular interest to us in this paper is the assumption about the “social” nature of design. Early research in computer-assisted design collaborations has jumped immediately into conclusions about communicative models which lead to high-bandwidth video connections as the preferred channel of collaboration. The unstated assumption is that computer-supported design environments are not adequate until they replicate in full the sensation of being physically present in the same space as the other participants (you are not there until you are really there). It is assumed that the real social process of design must include all the signals used to establish and facilitate face-to-face communication; including gestures; body language and all outputs of drawing (e.g. Tang [1991]). In our specification of systems for virtual design communities; are we about to fall into the same traps as drafting systems did?

summary The existing Caad systems limit designers creativity by constraining them to work with prototypes provided by the system's knowledge base. Most think of computers as drafting machines and consider CAAD models as merely proposals for future buildings. But this kind of thinking (computers as simple drafting machines) seems to be a way without future. New media demands new process and new process demands new media. We have to give some thougt to impact of CAAD on the design process and in which part of it CAAD can add new value. In this paper there will be considered two ways of using of computers. First - creation of architectural form in an architect's mind and projects visualisation with using renderings, animation and virtual reality. In the second part - computer techniques are investigated as a medium of creation. Unlike a conventional drawing the design object within computer has a life of its own. In computer space design and the final product are one. Computer creates environments for new kind of design activities. In fact, many dimensions of meaning in cyberspace have led to a cyberreal architecture that is sure to have dramatic consequences for the profession.

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

summary Generative design systems take an active part in the generation of computational design models. They make it easier for designers to explore conceptual alternatives, but the amount of information generated during a design session can become very large. Intelligent navigation aids are needed to enable designers to access the information with ease and low cognitive loads. We present an approach to support navigation in generative design systems. Our approach takes account of studies related to navigation in physical environments as well as information navigation in electronic media. Results of studies from the physical environment and electronic media reveal that 1) people exhibit similar cognitive behaviours (spatial cognition and the use of spatial knowledge) while navigating in physical and information spaces; and 2) the information space lacks legibility and imageability. The proposed information navigation model take these findings into account.

title Architecture in Landscape: Integrated CAD Environments for Contextually Situated Design
doi https://doi.org/10.52842/conf.ecaade.1997.x.q6p
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary This paper explores the future role of a more holistic and integrated approach to the design of architecture in landscape. Many of the design exploration and presentation techniques presently used by particular design professions do not lend themselves to an inherently collaborative design strategy.

Within contemporary digital environments, there are increasing opportunities to explore and evaluate design proposals which integrate both architectural and landscape aspects. The production of integrated design solutions exploring buildings and their surrounding context is now possible through the design development of shared 3-D and 4-D virtual environments, in which buildings no longer float in space.

The scope of landscape design has expanded through the application of techniques such as GIS allowing interpretations that include social, economic and environmental dimensions. In architecture, for example, object-oriented CAD environments now make it feasible to integrate conventional modelling techniques with analytical evaluations such as energy calculations and lighting simulations. These were all ambitions of architects and landscape designers in the 70s when computer power restricted the successful implementation of these ideas. Instead, the commercial trend at that time moved towards isolated specialist design tools in particular areas. Prior to recent innovations in computing, the closely related disciplines of architecture and landscape have been separated through the unnecessary development, in our view, of their own symbolic representations, and the subsequent computer applications. This has led to an unnatural separation between what were once closely related disciplines.

Significant increases in the performance of computers are now making it possible to move on from symbolic representations towards more contextual and meaningful representations. For example, the application of realistic materials textures to CAD-generated building models can then be linked to energy calculations using the chosen materials. It is now possible for a tree to look like a tree, to have leaves and even to be botanicaly identifiable. The building and landscape can be rendered from a common database of digital samples taken from the real world. The complete model may be viewed in a more meaningful way either through stills or animation, or better still, through a total simulation of the lifecycle of the design proposal. The model may also be used to explore environmental/energy considerations and changes in the balance between the building and its context most immediately through the growth simulation of vegetation but also as part of a larger planning model.

The Internet has a key role to play in facilitating this emerging collaborative design process. Design professionals are now able via the net to work on a shared model and to explore and test designs through the development of VRML, JAVA, whiteboarding and video conferencing. The end product may potentially be something that can be more easily viewed by the client/user. The ideas presented in this paper form the basis for the development of a dual course in landscape and architecture. This will create new teaching opportunities for exploring the design of buildings and sites through the shared development of a common computer model.

summary The aim of this project is to develop a software system for generating complex digital models of existing buildings and structures, i.e. in the broadest sense a computer-supported surveying and management system for existing buildings. The built environment is registered by surveying a series of geometrical and building relevant information broken down into different levels of abstraction. The recorded data consists of a variety of geometric, multimedia and verbal - less structured - pieces of information. The starting point for developing such a system is both an analysis and reworking of the methods used in architectural surveying, and the evaluation and use of current techniques and tools in the field of computer applications.

title Geometric Modeling
source New York: Wiley Computer Publishing
summary A comprehensive, up-to-date presentation of all the indispensable core concepts of geometric modeling. Now completely updated to reflect the most recent developments in the field, Geometric Modeling clearly presents and compares all the important mathematical approaches to modeling curves, surfaces, and solids, and shows how to shape and assemble these elements into more complex models. Its thorough coverage also includes the concomitant geometric processing necessary, e.g., the computation of intersections, offsets, and fillets. Written in a style that is virtually free of the jargon of special applications, this unique book focuses on the essence of geometric modeling and treats it as a discipline in its own right. This integrated approach allows the reader to focus on the principles and logic of geometric modeling without requiring background knowledge of CAD/CAM, computer graphics, or computer programming. Supported by more than 300 illustrations, Geometric Modeling appeals to the reader's visual and intuitive skills in a way that makes understanding the more abstract concepts much easier. This new edition features a host of new application areas, including topology, special effects in cinematography, the design and control of type fonts, and virtual reality, as well as numerous application examples. For computer graphics specialists, application designers and developers, scientific programmers, and advanced students, Geometric Modeling, Second Edition will serve as a complete and invaluable guide to the entire field.

title Interface to Architecture: Integrating Technology into the Environment in the Brain Opera
source Proceedings of DIS'97: Designing Interactive Systems: Processes, Practices, Methods, & Techniques 1997 pp. 265-275
summary This paper concretely presents the design processes and results of Composer Tod Machover's Brain Opera, an interactive, multi-media, traveling opera. It will present the importance of successful collaboration between artists and scientists at the functional intersection of their research -- design. It will discuss the opposing design strategies necessary for integrating technology into the physical environment at various levels of scale, from architecture to interface. At the level of architecture flexibility in design is stressed. In interface design, the needs for specificity and detail, new materials and manufacturing processes are presented. The paper will demonstrate how the aesthetic goals of the Brain Opera's visual designers, creating an organic, humorous and unexpected technology environment, influenced audience interaction. The conflict between artistic control and interactivity will also be examined through the specific results of acoustic design in the project. The influences of quickly changing technology and funding on the design of the Brain Opera are also revealed. The prominence of the proscenium arch stage in existing music venues and its influence on new media projects is presented. Successful and unsuccessful models for audience participation are also presented. Concrete interface examples are used to counter the notion of intuitive interface design. Finally, the Brain Opera is presented as a design model for an interactive research laboratory.

title Toward a procedure of computer simulation in the restoration of historical architecture

summary In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

source Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary This paper presents a method of using computer animation techniques in order to solve problems of visual pollution of city environment. It is our observation that human-inducted degradation of city environmental results from well - intentioned but inappropriate preservation actions by uninformed designers and local administration. Very often, a local municipality administration permits to build bad-fitting surroundings houses. It is usually connected with lack of visual information's about housing areas of a city, its features and characteristics. The CAMUS system (Computer Aided Management of Urban Structure) is being created at the Faculty of Architecture of Bialystok Technical University. One of its integral parts is VIA - Visual Impact of Architecture. The basic element of this system is a geometrical model of the housing areas of Bialystok. This model can be enhanced using rendering packages as they create the basis to check our perception of a given area. An inspiration of this approach was the digital endoscopy presented by J. Breen and M. Stellingwerff at the 2nd EAEA Conferences in Vienna. We are presenting the possibilities of using simple computer programs for analysis of spatial model. This contribution presents those factors of computer presentation which can demonstrate that computers achieve such effects as endoscope and often their use be much more efficient and effective.

summary The paper presents the implementation of a system of Shared Virtual Reality (SVR) in Internet applied to a large- scale project. The applications of SVR to architectural and urban design are presented in the context of a real project, the new railway junction of Porta Susa and the surrounding urban area in the city centre of Turin, Italy. SVR differs from Virtual Reality in that the experience of virtual spaces is no longer individual, but rather shared across the net with other users simultaneously connected. SVR offers an effective approach to Computer Supported Collaborative Work, because it integrates both the communicative tools to improve collaboration and the distributed environment to elaborate information across the networks.

summary The concept of ODE (Open Design Environment) and corresponding system were presented in 1991. Then the new concept of NODE. which is networked version of ODE. was generated to make wide area collaboration in 1994. The aim of our research is to facilitate the collaboration among the various people involved in the design process of an urban or architectural project. This includes various designers and engineers, the client and the citizens who may be affected by such a project. With the new technologies of hyper medium, network, and component architecture, we have developed NODE system and applied in practical use of the collaboration among the various people. This study emphasizes the interactive 3-D design tool of NODE which is able to make realistic and realtime presentation with interactive interface. In recent years, ProjectFolder of NODE system, which is a case including documents, plans, and tools to proceed project., is created in the World Wide Web (WWW) and makes hyper links between a 3-D object and a text, an image. and other digital data.

title Understanding Shared Space for Informal Interaction among Geographically Distributed Teams
source Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 41-54.
summary In a design project, much creative work is done in teams, thus requires spaces for collaborative works such as conference rooms, project rooms and chill-out areas. These spaces are designed to provide an atmosphere conducive to discussion and communication ranging from formal meetings to informal communication. According to Kraut et al (E.Kraut et al., 1990), informal communication is an important factor for the success of collaboration and is defined as “conversations take place at the time, with the participants, and about the topics at hand. It often occurs spontaneously by chance and in face-to-face manner. As shown in many research, much of good and creative ideas originate from impromptu meeting rather than in a formal meeting (Grajewski, 1993, A.Isaacs et al., 1997). Therefore, the places for informal communication are taken into account in workplace design and scattered throughout the building in order to stimulate face-to-face interaction, especially serendipitous communication among different groups across disciplines such as engineering, technology, design and so forth. Nowadays, team members of a project are not confined to people working in one location but are spread widely with geographically distributed collaborations. Being separated by long physical distance, informal interaction by chance is impossible since people are not co-located. In order to maintain the benefit of informal interaction in collaborative works, research endeavor has developed a variety ways to shorten the physical distance and bring people together in one shared space. Technologies to support informal interaction at a distance include video-based technologies, virtual reality technologies, location-based technologies and ubiquitous technologies. These technologies facilitate people to stay aware of other’s availability in distributed environment and to socialize and interact in a multi-users virtual environment. Each type of applications supports informal interaction through the employed technology characteristics. One of the conditions for promoting frequent and impromptu face-to-face communication is being co-located in one space in which the spatial settings play as catalyst to increase the likelihood for frequent encounter. Therefore, this paper analyses the degree to which sense of shared space is supported by these technical approaches. This analysis helps to identify the trade-off features of each shared space technology and its current problems. A taxonomy of shared space is introduced based on three types of shared space technologies for supporting informal interaction. These types are named as shared physical environments, collaborative virtual environments and mixed reality environments and are ordered increasingly towards the reality of sense of shared space. Based on the problem learnt from other technical approaches and the nature of informal interaction, this paper proposes physical-virtual shared space for supporting intended and opportunistic informal interaction. The shared space will be created by augmenting a 3D collaborative virtual environment (CVE) with real world scene at the virtual world side; and blending the CVE scene to the physical settings at the real world side. Given this, the two spaces are merged into one global structure. With augmented view of the real world, geographically distributed co-workers who populate the 3D CVE are facilitated to encounter and interact with their real world counterparts in a meaningful and natural manner.

title Building Design Advisor: automated integration of multiple simulation tools
source Automation in Construction 6 (4) (1997) pp. 341-352
summary The Building Design Advisor (BDA) is a software environment that supports the integrated use of multiple analysis and visualization tools throughout the building design process, from the initial, conceptual and schematic phases to the detailed specification of building components and systems. Based on a comprehensive design theory, the BDA uses an object-oriented representation of the building and its context, and acts as a data manager and process controller to allow building designers to benefit from the capabilities of multiple tools. The BDA provides a graphical user interface that consists of two main elements: the Building Browser and the Decision Desktop. The Browser allows building designers to quickly navigate through the multitude of descriptive and performance parameters addressed by the analysis and visualization tools linked to the BDA. Through the Browser the user can edit the values of input parameters and select any number of input and/or output parameters for display in the Decision Desktop. The Desktop allows building designers to compare multiple design alternatives with respect to multiple descriptive and performance parameters addressed by the tools linked to the BDA. The BDA is implemented as a Windows®-based application for personal computers. Its initial version is linked to a Schematic Graphic Editor (SGE), which allows designers to quickly and easily specify the geometric characteristics of building components and systems. For every object created in the SGE, the BDA activates a Default Value Selector (DVS) mechanism that selects `smart' default values from a Prototypes Database for all non-geometric parameters required as input to the analysis and visualization tools linked to the BDA. In addition to the SGE that is an integral part of its user interface, the initial version of the BDA is linked to a daylight analysis tool, an energy analysis tool, and a multimedia, Web-based Case Studies Database (CSD). The next version of the BDA will be linked to additional analysis tools, such as the DOE-2 (thermal, energy and energy cost) and RADIANCE (day/lighting and rendering) computer programs. Plans for the future include the development of links to cost estimating and environmental impact modules, building rating systems, CAD software and electronic product catalogs.

title Modelling for eye level composition; design media experiments in an educational setting.
source Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary In order to simulate the visual effects of designs at eye level, it is necessary to construct models from which (sequences of) images can be taken. This holds true for both Optical Endoscopy and Computer Aided Visualisation techniques. In what ways can an eye level approach stimulate spatial awareness and create insights into the workings of a design concept? Can Endoscopic methods be used effectively as a creative environment for design decision-making and teamwork and even to stimulate the generation of new design ideas? How should modelmaking be considered if it is to be of use in an ‘impatient’ design process, and how can students be made aware of the opportunities of both direct eye level observations from design models and of the more sophisticated endoscopic imaging techniques? This paper explores the theme of eye level modelling by focusing on a number of formal exercises and educational experiments carried out by the Delft Media group in recent years. An attempt is made to describe and evaluate these experiences, in order to draw conclusions and to signal possible new opportunities for eye level composition for the benefit of both design education and practice...

title Would be Worlds: How simulation is changing the frontiers of science
source John Wiley & Sons, Inc., New York.
summary Five Golden Rules is caviar for the inquiring reader. Anyone who enjoyed solving math problems in high school will be able to follow the author's explanations, even if high school was a long time ago. There is joy here in watching the unfolding of these intricate and beautiful techniques. Casti's gift is to be able to let the nonmathematical reader share in his understanding of the beauty of a good theory.-Christian Science Monitor "[Five Golden Rules] ranges into exotic fields such as game theory (which played a role in the Cuban Missile Crisis) and topology (which explains how to turn a doughnut into a coffee cup, or vice versa). If you'd like to have fun while giving your brain a first-class workout, then check this book out."-San Francisco Examiner "Unlike many popularizations, [this book] is more than a tour d'horizon: it has the power to change the way you think. Merely knowing about the existence of some of these golden rules may spark new, interesting-maybe even revolutionary-ideas in your mind. And what more could you ask from a book?"-New Scientist "This book has meat! It is solid fare, food for thought . . . makes math less forbidding, and much more interesting."-Ben Bova, The Hartford Courant "This book turns math into beauty."-Colorado Daily "John Casti is one of the great science writers of the 1990s."-San Francisco Examiner In the ever-changing world of science, new instruments often lead to momentous discoveries that dramatically transform our understanding. Today, with the aid of a bold new instrument, scientists are embarking on a scientific revolution as profound as that inspired by Galileo's telescope. Out of the bits and bytes of computer memory, researchers are fashioning silicon surrogates of the real world-elaborate "artificial worlds"-that allow them to perform experiments that are too impractical, too costly, or, in some cases, too dangerous to do "in the flesh." From simulated tests of new drugs to models of the birth of planetary systems and galaxies to computerized petri dishes growing digital life forms, these laboratories of the future are the essential tools of a controversial new scientific method. This new method is founded not on direct observation and experiment but on the mapping of the universe from real space into cyberspace. There is a whole new science happening here-the science of simulation. The most exciting territory being mapped by artificial worlds is the exotic new frontier of "complex, adaptive systems." These systems involve living "agents" that continuously change their behavior in ways that make prediction and measurement by the old rules of science impossible-from environmental ecosystems to the system of a marketplace economy. Their exploration represents the horizon for discovery in the twenty-first century, and simulated worlds are charting the course. In Would-Be Worlds, acclaimed author John Casti takes readers on a fascinating excursion through a number of remarkable silicon microworlds and shows us how they are being used to formulate important new theories and to solve a host of practical problems. We visit Tierra, a "computerized terrarium" in which artificial life forms known as biomorphs grow and mutate, revealing new insights into natural selection and evolution. We play a game of Balance of Power, a simulation of the complex forces shaping geopolitics. And we take a drive through TRANSIMS, a model of the city of Albuquerque, New Mexico, to discover the root causes of events like traffic jams and accidents. Along the way, Casti probes the answers to a host of profound questions these "would-be worlds" raise about the new science of simulation. If we can create worlds inside our computers at will, how real can we say they are? Will they unlock the most intractable secrets of our universe? Or will they reveal instead only the laws of an alternate reality? How "real" do these models need to be? And how real can they be? The answers to these questions are likely to change the face of scientific research forever.

title The use of genetic programming for applications in the field of spatial composition
source International Conference on Generative Art
summary Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.
