title	Linguistic Operation System for Design of Architectural Form
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	In a process of architectural design, an architect not only draws by himself/herself but also lets another person modify a design by given a linguistic instruction expressing how the design ought to be. In the case of utilization of CAD systems, it is useful if the system modifies the design according to the linguistic instruction. On the other hand, because of the recent increase of the opportunities of designing a building whose roof has complicated curved surface, it extremely takes labor to change the design. This paper proposes a linguistic operation system that modifies a design according to the linguistic instruction of the modification by the user to support design of a complicated form with curved surface. The proposed system is expected to be integrated with a CAD system. First, the system presents a perspective sketch of a designed form. From the values of the design variables that characterize the form in the system, the system calculates the position of the form in “the association image space.” Second, the designer puts a linguistic instruction i.e., words as like as “let it be more light” to modify the form. The words used for the instruction have the position in the association image space. In the association image space, the system moves the position of the form to a new position that gets to be near the position of the given word. The system calculates the values of the design variables of the form corresponding to the new position. We need a mapping from every vector representing the position of the changed form in the association image space to the corresponding vector representing the values of the design variables. To find the mapping, we construct a neural network system with three levels. Finally, the system presents a perspective sketch of changed form using the calculated values of design variables.

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

title	Development of a Wheelchair Virtual
source	3rd International Conference on Disability, VR and Associated Technologies, Sardinia, (Ed. P Sharkey) ICDVRAT2000, 1-8
summary	In the UK the Disability Discrimination Act 1995 aims to end discrimination against disabled people. Importantly the Act gives the disabled community new employment and access rights. Central to these rights will be an obligation for employers and organisations to provide premises which do not disadvantage disabled people. Many disabled people rely on wheelchairs for mobility. However, many buildings do not provide conditions suited to wheelchair users. This project aims to provide instrumentation allowing wheelchair navigation within virtual buildings. The provision of such instrumentation assists architects in identifying the needs of wheelchair users at the design stage. Central to this project is the need to provide a platform which can accommodate a range of wheelchair types, that will map intended wheelchair motion into a virtual world and that has the capacity to provide feedback to the user reflecting changes in floor surface characteristics and slope. The project represents a collaborative effort between architects, bioengineers and user groups and will be comprised of stages related to platform design, construction, interfacing, testing and user evaluation.

title	Aesthetic Evolutionary Design with Data Flow Networks
source	International Conference on Generative Art
summary	For a little over a decade, software has been created which allows for the design of visual content by aesthetic evolutionary design (AED) [3]. The great majority of these AED systems involve custom software intended for breeding entities within one fairly narrow problem domain, e.g., certain classes of buildings, cars, images, etc. [5]. Only a very few generic AED systems have been attempted, and extending them to a new design problem domain can require a significant amount of custom software development [6][8]. High end computer graphics software packages have in recent years become sufficiently robust to allow for flexible specification and construction of high level procedural models. These packages also provide extensibility, allowing for the creation of new software tools. One component of these systems which enables rapid development of new generative models and tools is the visual data flow network [1][2][7]. One of the first CG packages to employ this paradigm was Houdini. A system constructed within Houdini which allows for very fast generic specification of evolvable parametric prototypes is described [4]. The real-time nature of the software, when combined with the interlocking data networks, allows not only for vertical ancestor/child populations within the design space to be explored, but also allows for fast "horizontal" exploration of the potential population surface. Several example problem domains will be presented and discussed. References: [1] Alias \| Wavefront. Maya. 2000, http://www.aliaswavefront.com [2] Avid.

title	Developing an Algorithm for Topological Transformation
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 203-205
summary	This research intends to test the architectural application of Jean Piaget’s clinical observations, described in the book: The Child’s Conception of Space (Piaget, 1956), according to which topology is an ordering discipline, active in the human psyche. Earlier attempts, based on the principles of graph-theory, were able to cover only a narrow aspect of spatial relations, i.e. connectivity, and were mostly a-perceptional, visually mute. The “Spaceprint” method, explained and illustrated in co-author’s book: Thought Palaces (Magyar, 1999), through dimensional reduction, investigates volumetric, 3D characteristics and relationships with planar 2D configurations. These configurations, however, represent dual values: they are simultaneously the formal descriptors of both finite matter and (fragments of) infinite space. The so- called “Particular Spaceprint”, as a tool of design development in building, object, or urban scales, with the help of digital technology, could express - again simultaneously - qualities of an idea-gram and the visual, even tactile aspects of material reality. With topological surface-transformations, the “General Spaceprints”, these abstract yet visually active spatial formulas can be obtained.

title	Enhanced Boundary Representation: A Lingua Franca for Computer-Based Building Performance Simulation?
doi	https://doi.org/10.52842/conf.acadia.2000.012
source	ACADIA Quarterly, vol. 19, no. 4, pp. 12-14
summary	With the realistic visual representation of buildings on the computer having reached maturity, the emphasis has now shifted to the performance simulation of buildings on the computer. The challenge of performance simulation in computer-based models of buildings lies in the integration of various simulation techniques that require different kinds of building representations. Traditional simulation techniques for luminous, acoustic and thermal environments require different building representations. Thepaper proposes that an enhanced boundary representation is a viable, common building representation format for performance simulation of illumination levels, acoustical parameters and thermal comfort, thereby providing a building representation format for multi-domain performancesimulation on the computer. Simulation techniques that have been developed for radiosity-based modeling of illumination in buildings, radiation-based modeling of sound propagation in spatial enclosures, and the modeling of thermal comfort based on mean radiant temperatures, point to a convergence of techniques. These techniques can all work based on an enhanced boundary or surface representation of buildings. The paper suggests that an enhanced boundary representation format, and integrated performance simulation techniques based on radiation, can together serve as a core model for developers of computer-aided design analysis systems.

title	Synagogue Neudeggergasse: A Virtual Reconstruction in Vienna
doi	https://doi.org/10.52842/conf.acadia.2000.213
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 213-218
summary	Issues associated with virtual reconstruction are first dealt within this paper. Visualizing of no longer existent (architecture-) objects and their surroundings practically amounts to a “virtual comeback”. Furthermore, special attention is given to the description of the working procedure for a case study of reconstruction sounding out the potentials of QuickTime VR. The paper ends up with a set of conclusions, taking a close look at the “pros” and “cons” of this type of re-construction. 1 Introduction Irreversible destruction having removed identity-establishing buildings from the urban surface for all times is the principal cause for the attempt of renewed “imaginating.” When dealing with such reconstruction first the problem of reliability concerning the existing basic material has to be tackled. Due to their two-dimensional recording photographs only supply us with restricted information content of the object under consideration. Thus the missing part has to be supplemented or substituted by additional sources. Within the process of assembling and overlaying of differing data sets the way of dealing with such fragmentations becomes of major importance. Priority is given to the choice of information. One of the most elementary items of information regarding perception of three-dimensional objects surely is the effect that color and material furnishes. It seems to suggest itself that black-and-white shots hardly will prove valid in this respect. The three-dimensional object doubtlessly provides us with a by far greater variety of possibilities in the following working process than the “cardboard model with pasted-on facade photography”. Only the completely designed model structure makes for visualizing the plastic representation form of architecture in a sustainable manner. Furthermore, a virtual model can be dismantled into part models without amounting to a destruction process thereof. Apart therefrom the virtual model permits the generation of differing reconstruction variants regarding color and material. Moreover, architecture models of a physical nature are inherently connected to locality as such.

title	Controlling Chaos: a Simple Deterministic System for Creating Complex Organic Shapes
source	International Conference on Generative Art
summary	It is difficult and frustrating to create complex organic shapes using the current set of computer graphic programs. One reason is because the geometry of nature is different from that of our tools. Its self-similarity and fine detail are derived from growth processes that are very different from the working process imposed by drawing programs. This mismatch makesit difficult to create natural looking artifacts. Drawing programs provide a palette of shapes that may be manipulated in a variety ways, but the palette is limited and based on a cold Euclidean geometry. Clouds, rivers, and rocks are not lines or circles. Paint programs provide interesting filters and effects, but require great skill and effort. Always, the details must be arduously managed by the artist. This limits the artist's expressive power. Fractals have stunning visual richness, but the artist's techniques are limited to those of choosing colours and searching the fractal space. Genetic algorithms provide a powerful means for exploring a space of variations, but the artist's skill is limited by the very difficult ability to arrive at the correct fitness function. It is hard to get the picture you wanted. Ideally, the artist should have macroscopic control over the creation while leaving the computer to manage the microscopic details. For the result to feel organic, the details should be rich, consistent and varied, cohesive but not repetitious. For the results to be reproducible, the system should be deterministic. For it to be expressive there should be a cause-effect relationship between the actions in the program and change in the resulting picture. Finally, it would be interesting if the way we drew was more closely related to the way things grew. We present a simple drawing program which provides this mixture of macroscopic control with free microscopic detail. Through use of an accretion growth model, the artist controls large scale structure while varied details emerge naturally from senstive dependence in the system. Its algorithms are simple and deterministic, so its results are predictable and reproducible. The overall resulting structure can be anticipated, but it can also surprise. Despite its simplicity, it has been used to generate a surprisingly rich assortment of complex organic looking pictures.

summary	The textile surface presupposes infinite limits and contained in each one of its minimum parts the total information of the complete system, the singular sign that repeats itself with infinite criterion in a limited field. The textil proposes, simultaneously, the limit and the excess. The logic of the constructions by repetitions is based in the coordinated interaction of the part and the whole. IT CONSTITUTES A SYSTEM, with variations from simplicity to complexity, in the estructural morphology and in the surface. The recuperation of a totality/ continuity concept in a teaching- learning strategy, implicates the manage in all senses of a multidirectionel space, today indispensable, in the convivences of the analogic and the digital. Immersed into a culture that repeats the fragments on a seduction of the representation to the representation itself, the generation of a place of flexibility and interaction is the instance to the knowledge construction.

summary	This article describes VRAM, short for Virtual Reality Aided Modeler. VRAM is a conceptual design tool supported by Virtual Reality technology and an ongoing testbed for theory and methodology in the field of three dimensional user interfaces (3DUIs). The outcomes from the project should consist of an intuitive and comprehensive immersive surface modeler, next to a set of taxonomies and guidelines for the development of 3DUIs. Based on a modular structure, VRAMs program architecture allows the easy extension of functionality. The application consists of the seamless integration of four main functionality modules, namely system control, viewing & browsing, editing and modeling. Based on the premise of portability, the software environment runs on both SGI Irix and MS Windows NT platforms. To be relatively independent in developing 3DUI techniques, the VRAM environment supports a multiplicity of input and output devices. Due to the focus on immersive modeling, tracking devices, head mounted displays and stereoprojection devices are the main I/O channels. In this article, we will primary focus on the functionality of the virtual modeller.

title	A catalogue of built forms, using a binary representation
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	A technique is described for the representation of a class of rectangular built forms. Each individual form is produced by applying a series of transformations to a single generic or ‘archetypal’ form, which is designed to take care of the broad constraints, on built space, of close-packing and the requirements for natural light and views. Parts of the archetype which are selected for inclusion in any particular built form are then designated by 1s, and parts which are suppressed by 0s. This makes it possible to assign a unique binary code to each different (undimensioned) built form produced from the archetype. Binary codes corresponding to all legitimate forms may then be arranged in ascending order, to create a comprehensive catalogue. The paper describes such a catalogue comprising forms with up to four courtyards, described by 22-digit binary strings. Metric values may be assigned to the various dimensions of each form, making it a matter of simple arithmetic to compute such attributes as volume, surface area, minimum site area or floor space index. From logical operations on the binary strings it is possible to identify a series of configurational characteristics of the corresponding forms, such as their overall plan shapes, the number of courtyards or the potential for symmetry. The catalogue may thus be searched for built forms fulfilling some set of specifications, for example total floor area, site size and certain desired shape attributes. Worked examples are illustrated from the design of multi-storey office buildings. Possible applications are suggested for this approach, in architectural science and the early strategic stages of architectural design.

The transposition of the hypertext model to architectural and urban concepts question the mutation of the spatial and semantic construct of space. The definition of architecture as a code is based on “glocal” systems according to the processes of computation and communication.

summary	Since 1991 Virtual Reality has been used in student projects in the Building Information Technology group. It started as an experimental tool to assess the impact of VR technology in design, using the environment of the associated Calibre Institute. The technology was further developed in Calibre to become an important presentation tool for assessing design variants and final design solutions. However, it was only sporadically used in student projects. A major shift occurred in 1997 with a number of student projects in which various computer technologies including VR were used in the whole of the design process. In 1998, the new Design Systems group started a design studio with the explicit aim to integrate VR in the whole design process. The teaching effort was combined with the research program that investigates VR as a design support environment. This has lead to increasing number of innovative student projects. The paper describes the context and history of VR in Eindhoven and presents the current set-UP of the studio. It discusses the impact of the technology on the design process and outlines pedagogical issues in the studio work.

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

summary	Although recent technology in time-based representation has vastly improved, animation in virtual prototype design field remains the same. Some designers invest a huge amount of money in the latest visualisation and multimedia technology and yet may create even worse animation. They often cramp sequences resulting in many viewers failing to interpret the design positively as they miss a lot of vital information that explains the design. This paper basically reports the importance of film-making understanding for producing good virtual prototype animation. It will be based on a part of a research project on the use of time-based media in architectural practices. It also includes an empirical analysis of several architectural-based documentary films (including an interview with the film director) and past and present computer animation. This paper then concludes with recommendations of good techniques for making animated visualisation relative to the stage at which the animation is produced for better design decision.

summary	Ever-increasing complexity in product design and the need to deliver a cost-effective solution that benefits from a dynamic approach requires the employment and adoption of innovative design methods which ensure that products are of the highest quality and meet or exceed customers' expectations. According to Bronowski (1976) science and art were originally two faces of the same human creativity. However, as civilisation advances and works became specialised, the dichotomy of science and art gradually became apparent. Hence scientists and artists were born, and began to develop work that was polar opposite. The sense of beauty itself became separated from science and was confined within the field of art. This dichotomy existed through mankind's efforts in advancing civilisation to its present state. This paper briefly examines the relationship between art and science through the ages and discusses their relatively recent re-convergence. Based on this hypothesis, this paper studies the current state of the convergence between arts and sciences and examines the current relationship between the two by considering real world applications and products. The study of such products and their successes and impact they had in the marketplace due to their designs and aesthetics rather than their advanced technology that had partially failed them appears to support this argument. This text further argues that a re-convergence between art and science is currently occurring and highlights the need for accelerating this process. It is suggested that re-convergence is a result of new technologies which are adopted by practitioners that include effective visualisation and communication of ideas and concepts. Such elements are widely found today in multimedia and Virtual Environments (VEs) where such tools offer increased power and new abilities to both scientists and designers as both venture in each other's domains. This paper highlights the need for the employment of emerging computer based real-time interactive technologies that are expected to enhance the design process through real-time prototyping and visualisation, better decision-making, higher quality communication and collaboration, lessor error and reduced design cycles. Effective employment and adoption of innovative design methods that ensure products are delivered on time, and within budget, are of the highest quality and meet customer expectations are becoming of ever increasing importance. Such tools and concepts are outlined and their roles in the industries they currently serve are identified. Case studies from differing fields are also studied. It is also suggested that Virtual Reality interfaces should be used and given access to Computer Aided Design (CAD) model information and data so that users may interrogate virtual models for additional information and functionality. Adoption and appliance of such integrated technologies over the Internet and their relevance to electronic commerce is also discussed. Finally, emerging software and hardware technologies are outlined and case studies from the architecture, electronic games, and retail industries among others are discussed, the benefits are subsequently put forward to support the argument. The requirements for adopting such technologies in financial, skills required and process management terms are also considered and outlined.
