title	Evaluating Office Buildings with MOLCA(Model for Office Life Cycle Assessment)
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	MOLCA (Model for Office Life Cycle Assessment) is a project that aims to develop a tool that enables designers and builders to evaluate the environmental impact of their designs (of office buildings) from a environmental point of view. The model used is based on guidelinesgiven by ISO 14000, using the so-called Life Cycle Assessment (LCA) method. The MOLCA project started in 1997 and will be finished in 2001 resulting in the aforementioned tool. MOLCA is a module within broader research conducted at the Eindhoven University of Technology aiming to reduce design risks to a minimum in the early design stages.Since the MOLCA project started two major case-studies have been carried out. One into the difference in environmental load caused by using concrete and steel roof systems respectively and the role of recycling. The second study focused on biases in LCA data and how to handle them. For the simulations a computer-model named SimaPro was used, using the world-wide accepted method developed by CML (Centre for the Environment, Leiden, the Netherlands). With this model different life-cycle scenarios were studied and evaluated. Based on those two case studies and a third one into an office area, a first model has been developed.Bottle-neck in this field of study is estimating average recycling and re-use percentages of the total flow of material waste in the building sector and collecting reliable process data. Another problem within LCA studies is estimating the reliability of the input data and modelling uncertainties. All these topics will be subject of further analysis.

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.

summary	Computer Numeric Controlled (CNC) fabrication machineries are changing the way we design and build. These technologies have increased productivity through greater efficiencies and have helped to create new forms of practice, including increased specializations and broader collaborative approaches. (Kieran Timberlake 2003: 31). However, some argue that these technologies can have a de-humanizing effect, stripping the human touch away from the production of objects and redistributing the associated skills to machines. (Dormer 1997: 103). The (Digital) Craft studio explored the notions of technology and craft to understand how and when designers should exploit the tools employed (both the hand and the machine) during the design and production processes.

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	Integrating Design Tools within a Human Collaborative Working Context
source	International Journal of Construction IT, Vol5, No 2, pp 35-53
summary	Integrating design tools has been an important research subject. The work to be reported in this paper differs from many previous efforts in that it not only tackles tool-tool interoperation, but also does so within a human collaborative working context We suggest that design integration support should include not only tool interoperability, but also mechanisms for co-ordinate and control the tool use. We also argue that the higher-level management support should include not only formalised and automated mechanisms, but also semi-automated and even informal mechanisms for human designers to directly interact with each other. Within a collaborative working framework, we'll present a hybrid architecture for tool integration, in which the human designers and the design tools are assumed to be distributed while the management is centralised. In this approach, each design tool is wrapped as an autonomous service provider with its own data store; thus the project design data is physically distributed with the design tools. A meta-data augmented product model, which populates a central meta-data repository serving as a "map" for locating the distributed design objects, is devised to provide a common vocabulary for communications and to assist the management of the distributed resources and activities. A design object broker is used to mediate among the distributed tools, and the central meta-data repository. The reported work has been part of a collaborative design system called virtual studio environment We'll illustrate how the integrated design tools might be used in human design work within the virtual studio environment.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 787-800
summary	This paper depicts the studies of the differences between human designers and computers in analogical reasoning and case adaptation. Four design experiments are undertaken to examine how designers conduct case-based design, apply dimensional and topological adaptation. The paper also examines the differences of case adaptation by novice and experienced designers, and between human judgement in case adaptation and the evaluation mechanism by providing similarity assessment. In conclusion, this study provides the comparative analysis from the above observation and implications on the development of case-based reasoning systems for designers.

title	Analogical Reasoning in Architectural Design: Comparison of Human Designers and Computers in Case Adaptation
doi	https://doi.org/10.52842/conf.caadria.1997.205
source	CAADRIA ‘97 [Proceedings of the Second Conference on Computer Aided Architectural Design Research in Asia / ISBN 957-575-057-8] Taiwan 17-19 April 1997, pp. 205-215
summary	Design cases were considered as the design solution or condensed knowledge of design experience. In the analogical reasoning process, case adaptation is the fundamental task for solving the problem. This paper is aimed to study the difference between human designers and computers in case adaptation. Two design experiments are undertaken for examining how designers apply dimensional and topological adaptation, exploring the difference of case adaptation by novice and experienced designers, and examining the difference between human judgement in case adaptation and the evaluation mechanism by providing similarity assessment. In conclusion, this study provides the comparative analysis from the above observation and implications on the development of case-based reasoning systems for designers.

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	Design Speech Acts. "How To Do Things with Words" in Virtual Communities
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 707-717
summary	Cyberspace is language based, and so are Virtual Communities (VCs). We propose that VCs are ideal places to experience and enhance a language for design. Design in a VC can actually be performed using speech acts that in-real-life wouldn't perform any design. We call these acts 'design speech acts'. We present, as a starting point, a list of verbs which can be used in a VC for design and the implications of using these verbs to design cyberspace. We present a methodology for structuring and defining design speech acts, so that a language for design in a VC can be subsequently developed. We are developing a specific environment for a virtual community in which designers can articulate their needs and produce text-based design objects.

title	Design and Modelling in a Computer Integrated Construction Process - The BAS-CAAD Project
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 501-518
summary	A new approach to product modelling in a design context is proposed. CAD-software must not only enable product modelling, but must also support product design. This is not fully achieved in the traditional 'enumerative' approach to product modelling. We discuss how product design and modelling can be based on a facetted' approach to information modelling, and how a data model that supports the design process can be based on a framework for system information. The background for our research is the current development in the construction industry towards a computer integrated construction process. A first prerequisite for this is the use of computer based models. Another prerequisite is that CAD-software can support the design of the results of the construction process, including construction works, user organisations, and the production and facility management processes. A third prerequisite is that computer based models are built with standardised concepts and terminology to enable exchange of information between different actors and computer systems during different stages of the construction process. Principles for organising frameworks for user organisation and construction works information are presented in an appendix.

title	Information management in creative engineering design and capabilities of database transactions
source	Automation in Construction 7 (1) (1997) pp. 55-69
summary	This paper examines the information management requirements and sets forth the general criteria for collaboration and concurrency control in creative engineering design. Our work attempts to recognize the full range of concurrency, collaboration and complex transactions structure now practiced in manual and semi-automated design and the range of capabilities needed as the demands for enhanced but flexible electronic information management unfolds.The objective of this paper is to identify new issues that may advance the use of databases to support creative engineering design. We start with a generalized description of the structure of design tasks and how information management in design is dealt with today. After this review, we identify extensions to current information management capabilities that have been realized and/or proposed to support/augment what designers can do now.Given this capability-based starting point, we review existing database and information management capabilities, as presented in the literature. In the review, we identify the gaps between current concurrency and collaboration technology and what is needed or would be desirable. Our objective is to assess current research and to identify new issues that may advance the use of databases to support creative engineering design.

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	Design and Analysis
source	New York: Van Nostrand Reinhold
summary	Design and Analysis by Bernard Leupen, Christoph Grafe, Nicola Körnig, Marc Lampe, and Peter de Zeeuw Design and Analysis is an insightful, interdisciplinary exploration of the diversity of analytic methods used by architects, designers, urban planners, and landscape architects to understand the structure and principles of the built environment. Developed by a team headed by Bernard Leupen at Delft University of Technology, The Netherlands, Design and Analysis defies borders of history, geography, and discipline, tracing the evolution of design principles from ancient Greece to the 20th century. "Only methodical analysis gives us an insight into the design process," states architect Bernard Tschumi. Using historical examples from architecture, urban design, and landscape architecture, Design and Analysis defines an ordered system that enables the design student or professional to identify the factors that influence designers' decisions, and shows how to relate them to the finished project. Design and Analysis is organized into six chapters that correspond to these factors: order and composition, functionality, structure, typology, context, and analytical techniques. The authors introduce the analytical drawing as a time-tested means to obtaining insight into the design process. Over 100 line drawings are featured in all. Using contemporary architectural examples to teach ancient design principles, Design and Analysis is more than just an introduction to analytical methods. The authors give an outline of space design as a whole, from individual buildings to urban and landscape ensembles. Though primarily intended for design students to help them appreciate many of the issues that they will face as professionals, Design and Analysis's broad, easy-to-read approach makes it an invaluable handbook for designers of all disciplines.

title	Using argumentative agents to catalyze and support collaboration in design
source	Automation in Construction 6 (4) (1997) pp. 299-309
summary	Since the 1970s, we have created hypertext systems supporting Rittel's argumentative approach to design. Our efforts aim at improving design by encouraging argumentative, i.e., reasoned-discourse during projects. Despite the intrinsically group-oriented character of the argumentative approach, all of our past prototypes were single-user systems. The project reported here is the first in which we aim at supporting argumentation in group projects. To do this, we augmented our PHIDIAS hyperCAD system to show how argumentative agents can initiate and sustain productive collaboration in design. These agents catalyze collaboration among designers working at different times and/or places by (1) detecting overlaps in the concerns of different participants in a design process, including conflict and support relationships, (2) notifying these people of these overlapping concerns, and (3) enabling a synchronous communication among these people to deal collaboratively with the overlaps. We call these agents argumentative because they represent different personal and professional viewpoints in design and because they promote argumentative discourse among designers about various issues. In addition to identifying and dealing with crucial problems of coordination and collaboration, argumentative agents enable the capture of important design rationale in the form of communication among project participants about these crucial problems.

title	Supporting Collective Intelligence for Design in Virtual Worlds: A Case Study of the Lego Universe
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. 637-652.
summary	Virtual worlds are multi-faceted technologies. Facets of virtual worlds include graphical simulation tools, communication, design and modelling tools, artificial intelligence, network structure, persistent object-oriented infrastructure, economy, governance and user presence and interaction. Recent studies (Merrick et al., 2010) and applications (Rosenman et al., 2006; Maher et al., 2006) have shown that the combination of design, modelling and communication tools, and artificial intelligence in virtual worlds makes them suitable platforms for supporting collaborative design, including human-human collaboration and human-computer co-creativity. Virtual worlds are also coming to be recognised as a platform for collective intelligence (Levy, 1997), a form of group intelligence that emerges from collaboration and competition among large numbers of individuals. Because of the close relationship between design, communication and virtual world technologies, there appears a strong possibility of using virtual worlds to harness collective intelligence for supporting upcoming ‚Äúdesign challenges on a much larger scale as we become an increasingly global and technological society‚Äù (Maher et al, 2010), beyond the current support for small-scale collaborative design teams. Collaborative design is relatively well studied and is characterised by small-scale, carefully structured design teams, usually comprising design professionals with a good understanding of the design task at hand. All team members are generally motivated and have the skills required to structure the shared solution space and to complete the design task. In contrast, collective design (Maher et al, 2010) is characterised by a very large number of participants ranging from professional designers to design novices, who may need to be motivated to participate, whose contributions may not be directly utilised for design purposes, and who may need to learn some or all of the skills required to complete the task. Thus the facets of virtual worlds required to support collective design differ from those required to support collaborative design. Specifically, in addition to design, communication and artificial intelligence tools, various interpretive, mapping and educational tools together with appropriate motivational and reward systems may be required to inform, teach and motivate virtual world users to contribute and direct their inputs to desired design purposes. Many of these world facets are well understood by computer game developers, as level systems, quests or plot and achievement/reward systems. This suggests the possibility of drawing on or adapting computer gaming technologies as a basis for harnessing collective intelligence in design. Existing virtual worlds that permit open-ended design ‚Äì such as Second Life and There ‚Äì are not specifically game worlds as they do not have extensive level, quest and reward systems in the same way as game worlds like World of Warcraft or Ultima Online. As such, while Second Life and There demonstrate emergent design, they do not have the game-specific facets that focus users towards solving specific problems required for harnessing collective intelligence. However, a new massively multiplayer virtual world is soon to be released that combines open-ended design tools with levels, quests and achievement systems. This world is called Lego Universe (www.legouniverse.com). This paper presents technology spaces for the facets of virtual worlds that can contribute to the support of collective intelligence in design, including design and modelling tools, communication tools, artificial intelligence, level system, motivation, governance and other related facets. We discuss how these facets support the design, communication, motivational and educational requirements of collective intelligence applications. The paper concludes with a case study of Lego Universe, with reference to the technology spaces defined above. We evaluate the potential of this or similar tools to move design beyond the individual and small-scale design teams to harness large-scale collective intelligence. We also consider the types of design tasks that might best be addressed in this manner.

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	Cyber Design Studio: Using Manual Media Via Internet Connections for Collaborative Design
doi	https://doi.org/10.52842/conf.ecaade.1997.x.c9n
source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	This article explores how Computer Aided Design (CAD) systems can be applicable and integrated into the early stage of design. CAD systems are still technologies that are not broadly accepted as useful to the designer especially in this stage of design because CAD systems use the monitor and mouse which differ from the sketch paper and pen of manual media. This article discusses how manual media and Computer-Mediated Communication (CMC) technologies - video conferencing, in my examples - that employ multimedia and Internet can empower designers by providing them with new ways of working together. For accommodating this approach, a prototype CAD system has been developed in which the system consists of a conventional drawing and extra capabilities. This system allows the designer to work with computer based and paper based tools in the same conventional environment as well as remote communications between the designers. This environment is used as the setting for a case study of design tutorials in the design studio. The analysis of this work provides interesting insight into the traditional roles of design studio as well as the relationship between digital and manual media.

title	Design Evaluation Based on Virtual Representation of Spaces
doi	https://doi.org/10.52842/conf.acadia.1997.111
source	Design and Representation [ACADIA ‘97 Conference Proceedings / ISBN 1-880250-06-3] Cincinatti, Ohio (USA) 3-5 October 1997, pp. 111-120
summary	When spaces are evaluated, clients and architects often discuss design proposals by looking down at scale models. This overhead perspective forces viewers to imagine themselves looking and moving about within the model. Misperceptions may well result from such a point of view. With the advancement in virtual reality (VR) technology, and with its rising popularity in architecture, it is becoming plausible to consider using VR to evaluate design projects. The projects presented here are of three types: (1.) The first project compares people's evaluation of several slightly modified virtual models of a space. (2.) The second project compares how people evaluate a foam core model of a space to how they evaluate a virtual representation of the same space (3.) The third project compares people's evaluation of a real space to that of a virtual representation of this space. // The wide range of results presented provides one argument in support of using VR simulations to study spaces and how they are perceived. For example, results shows that a virtual window serves to alleviate perceived crowding and that added furniture serves to make a virtual room feel slightly larger and less constraining. However, problems did emerge with using virtual reality simulations to gain information about peoples' behavioral reactions to a space. Thus, not all circumstances under which VR representations are used creates valid results. Differences appear to be in the type of evaluations measured (e.g. dimensional versus behavioral). More research is needed to clarify this issue.

summary	Years of trying to create an "Image Idea Generator" program have convinced me that the perfect solution would be to have an artificial artistic person, a design slave. This paper describes how I came to that conclusion, realistic alternatives, and briefly, how it could possibly happen. 1. The history of Repligator and Gliftic 1.1 Repligator In 1996 I had the idea of creating an “image idea generator”. I wanted something which would create images out of nothing, but guided by the user. The biggest conceptual problem I had was “out of nothing”. What does that mean? So I put aside that problem and forced the user to give the program a starting image. This program eventually turned into Repligator, commercially described as an “easy to use graphical effects program”, but actually, to my mind, an Image Idea Generator. The first release came out in October 1997. In December 1998 I described Repligator V4 [1] and how I thought it could be developed away from simply being an effects program. In July 1999 Repligator V4 won the Shareware Industry Awards Foundation prize for "Best Graphics Program of 1999". Prize winners are never told why they won, but I am sure that it was because of two things: 1) Easy of use 2) Ease of experimentation "Ease of experimentation" means that Repligator does in fact come up with new graphics ideas. Once you have input your original image you can generate new versions of that image simply by pushing a single key. Repligator is currently at version 6, but, apart from adding many new effects and a few new features, is basically the same program as version 4. Following on from the ideas in [1] I started to develop Gliftic, which is closer to my original thoughts of an image idea generator which "starts from nothing". The Gliftic model of images was that they are composed of three components: 1. Layout or form, for example the outline of a mandala is a form. 2. Color scheme, for example colors selected from autumn leaves from an oak tree. 3. Interpretation, for example Van Gogh would paint a mandala with oak tree colors in a different way to Andy Warhol. There is a Van Gogh interpretation and an Andy Warhol interpretation. Further I wanted to be able to genetically breed images, for example crossing two layouts to produce a child layout. And the same with interpretations and color schemes. If I could achieve this then the program would be very powerful. 1.2 Getting to Gliftic Programming has an amazing way of crystalising ideas. If you want to put an idea into practice via a computer program you really have to understand the idea not only globally, but just as importantly, in detail. You have to make hard design decisions, there can be no vagueness, and so implementing what I had decribed above turned out to be a considerable challenge. I soon found out that the hardest thing to do would be the breeding of forms. What are the "genes" of a form? What are the genes of a circle, say, and how do they compare to the genes of the outline of the UK? I wanted the genotype representation (inside the computer program's data) to be directly linked to the phenotype representation (on the computer screen). This seemed to be the best way of making sure that bred-forms would bare some visual relationship to their parents. I also wanted symmetry to be preserved. For example if two symmetrical objects were bred then their children should be symmetrical. I decided to represent shapes as simply closed polygonal shapes, and the "genes" of these shapes were simply the list of points defining the polygon. Thus a circle would have to be represented by a regular polygon of, say, 100 sides. The outline of the UK could easily be represented as a list of points every 10 Kilometers along the coast line. Now for the important question: what do you get when you cross a circle with the outline of the UK? I tried various ways of combining the "genes" (i.e. coordinates) of the shapes, but none of them really ended up producing interesting shapes. And of the methods I used, many of them, applied over several "generations" simply resulted in amorphous blobs, with no distinct family characteristics. Or rather maybe I should say that no single method of breeding shapes gave decent results for all types of images. Figure 1 shows an example of breeding a mandala with 6 regular polygons: Figure 1 Mandala bred with array of regular polygons I did not try out all my ideas, and maybe in the future I will return to the problem, but it was clear to me that it is a non-trivial problem. And if the breeding of shapes is a non-trivial problem, then what about the breeding of interpretations? I abandoned the genetic (breeding) model of generating designs but retained the idea of the three components (form, color scheme, interpretation). 1.3 Gliftic today Gliftic Version 1.0 was released in May 2000. It allows the user to change a form, a color scheme and an interpretation. The user can experiment with combining different components together and can thus home in on an personally pleasing image. Just as in Repligator, pushing the F7 key make the program choose all the options. Unlike Repligator however the user can also easily experiment with the form (only) by pushing F4, the color scheme (only) by pushing F5 and the interpretation (only) by pushing F6. Figures 2, 3 and 4 show some example images created by Gliftic. Figure 2 Mandala interpreted with arabesques Figure 3 Trellis interpreted with "graphic ivy" Figure 4 Regular dots interpreted as "sparks" 1.4 Forms in Gliftic V1 Forms are simply collections of graphics primitives (points, lines, ellipses and polygons). The program generates these collections according to the user's instructions. Currently the forms are: Mandala, Regular Polygon, Random Dots, Random Sticks, Random Shapes, Grid Of Polygons, Trellis, Flying Leap, Sticks And Waves, Spoked Wheel, Biological Growth, Chequer Squares, Regular Dots, Single Line, Paisley, Random Circles, Chevrons. 1.5 Color Schemes in Gliftic V1 When combining a form with an interpretation (described later) the program needs to know what colors it can use. The range of colors is called a color scheme. Gliftic has three color scheme types: 1. Random colors: Colors for the various parts of the image are chosen purely at random. 2. Hue Saturation Value (HSV) colors: The user can choose the main hue (e.g. red or yellow), the saturation (purity) of the color scheme and the value (brightness/darkness) . The user also has to choose how much variation is allowed in the color scheme. A wide variation allows the various colors of the final image to depart a long way from the HSV settings. A smaller variation results in the final image using almost a single color. 3. Colors chosen from an image: The user can choose an image (for example a JPG file of a famous painting, or a digital photograph he took while on holiday in Greece) and Gliftic will select colors from that image. Only colors from the selected image will appear in the output image. 1.6 Interpretations in Gliftic V1 Interpretation in Gliftic is best decribed with a few examples. A pure geometric line could be interpreted as: 1) the branch of a tree 2) a long thin arabesque 3) a sequence of disks 4) a chain, 5) a row of diamonds. An pure geometric ellipse could be interpreted as 1) a lake, 2) a planet, 3) an eye. Gliftic V1 has the following interpretations: Standard, Circles, Flying Leap, Graphic Ivy, Diamond Bar, Sparkz, Ess Disk, Ribbons, George Haite, Arabesque, ZigZag. 1.7 Applications of Gliftic Currently Gliftic is mostly used for creating WEB graphics, often backgrounds as it has an option to enable "tiling" of the generated images. There is also a possibility that it will be used in the custom textile business sometime within the next year or two. The real application of Gliftic is that of generating new graphics ideas, and I suspect that, like Repligator, many users will only understand this later. 2. The future of Gliftic, 3 possibilties Completing Gliftic V1 gave me the experience to understand what problems and opportunities there will be in future development of the program. Here I divide my many ideas into three oversimplified possibilities, and the real result may be a mix of two or all three of them. 2.1 Continue the current development "linearly" Gliftic could grow simply by the addition of more forms and interpretations. In fact I am sure that initially it will grow like this. However this limits the possibilities to what is inside the program itself. These limits can be mitigated by allowing the user to add forms (as vector files). The user can already add color schemes (as images). The biggest problem with leaving the program in its current state is that there is no easy way to add interpretations. 2.2 Allow the artist to program Gliftic It would be interesting to add a language to Gliftic which allows the user to program his own form generators and interpreters. In this way Gliftic becomes a "platform" for the development of dynamic graphics styles by the artist. The advantage of not having to deal with the complexities of Windows programming could attract the more adventurous artists and designers. The choice of programming language of course needs to take into account the fact that the "programmer" is probably not be an expert computer scientist. I have seen how LISP (an not exactly easy artificial intelligence language) has become very popular among non programming users of AutoCAD. If, to complete a job which you do manually and repeatedly, you can write a LISP macro of only 5 lines, then you may be tempted to learn enough LISP to write those 5 lines. Imagine also the ability to publish (and/or sell) "style generators". An artist could develop a particular interpretation function, it creates images of a given character which others find appealing. The interpretation (which runs inside Gliftic as a routine) could be offered to interior designers (for example) to unify carpets, wallpaper, furniture coverings for single projects. As Adrian Ward [3] says on his WEB site: "Programming is no less an artform than painting is a technical process." Learning a computer language to create a single image is overkill and impractical. Learning a computer language to create your own artistic style which generates an infinite series of images in that style may well be attractive. 2.3 Add an artificial conciousness to Gliftic This is a wild science fiction idea which comes into my head regularly. Gliftic manages to surprise the users with the images it makes, but, currently, is limited by what gets programmed into it or by pure chance. How about adding a real artifical conciousness to the program? Creating an intelligent artificial designer? According to Igor Aleksander [1] conciousness is required for programs (computers) to really become usefully intelligent. Aleksander thinks that "the line has been drawn under the philosophical discussion of conciousness, and the way is open to sound scientific investigation". Without going into the details, and with great over-simplification, there are roughly two sorts of artificial intelligence: 1) Programmed intelligence, where, to all intents and purposes, the programmer is the "intelligence". The program may perform well (but often, in practice, doesn't) and any learning which is done is simply statistical and pre-programmed. There is no way that this type of program could become concious. 2) Neural network intelligence, where the programs are based roughly on a simple model of the brain, and the network learns how to do specific tasks. It is this sort of program which, according to Aleksander, could, in the future, become concious, and thus usefully intelligent. What could the advantages of an artificial artist be? 1) There would be no need for programming. Presumbably the human artist would dialog with the artificial artist, directing its development. 2) The artificial artist could be used as an apprentice, doing the "drudge" work of art, which needs intelligence, but is, anyway, monotonous for the human artist. 3) The human artist imagines "concepts", the artificial artist makes them concrete. 4) An concious artificial artist may come up with ideas of its own. Is this science fiction? Arthur C. Clarke's 1st Law: "If a famous scientist says that something can be done, then he is in all probability correct. If a famous scientist says that something cannot be done, then he is in all probability wrong". Arthur C Clarke's 2nd Law: "Only by trying to go beyond the current limits can you find out what the real limits are." One of Bertrand Russell's 10 commandments: "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric" 3. References 1. "From Ramon Llull to Image Idea Generation".

summary	This paper explores the impact of information technology on the architectural design process as seen through different design studios from three schools of architecture in Southern California over a two year period. All three studios tested notions of representation, simulation and the design process in relation to a post-industrial world and its impact on how we design for it. The sites for two of these studios were in the city of Berlin, where the spearhead of the information age and a leftover of the industrial revolution overlap in an urban condition that is representative of our world after the cold war. The three studios describe a progressive shift in the use of information technology in the design process, from nearly pure image-driven simulation to a more low-tech, highly creative uses of everyday computing tools. Combined, all three cases describe an array of scenarios for content-supportive uses of digital media in a design studio. The first studio described here, from USC, utilized computer modeling and visualization to design a building for a site located within the former no-mans' land of the Berlin Wall. The second studio, from SCI-Arc, produced an urban design proposal for an area along the former Berlin Wall and included a pan-geographic design collaboration via Internet between SCI-Arc/Los Angeles and SCI-Arc/Switzerland. The third and last studio from Woodbury University participated in the 1997 ACSA/Dupont Laminated Glass Competition designing a consulate general for Germany and one for Hong Kong. They employed a hybrid digital/non-digital process extracting experiential representations from simple chipboard study models and then using that information to explore an "enhanced model" through digital imaging processes. The end of the cold war was coincidental with the explosive popularization of information technology as a consumer product and is poised to have huge impact on how and what we design for our cities. Few places in world express this potential as does the city of Berlin. These three undergraduate design studios employed consumer-grade technology in an attempt to make a difference in how we design, incorporating discussions of historical change, ideological premise and what it means to be an architect in a world where image and content can become easily disconnected from one another.
