title The Dynamics of Physical Ambiences

source Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 174-181
summary This research proposes to support the reading of physical ambiences by the development of a representational technique which compiles, in a numerical interface, two types of data: sensory and filmic. These data are recorded through the use of a portable array equipped with sensors (Potvin 1997, 2002, 2004) as well as the acquisition of Video information of the moving environment. The compilation of information is carried out through a multi-media approach, by means of a program converting the environmental data into dynamic diagrams, as well as the creation of an interactive interface allowing a possible diffusion on the Web. This technique, named APMAP/Video, makes it possible to read out simultaneously spatial and environmental diversity. It is demonstrated through surveys taken at various seasons and time of the day at the new Caisse de dépôt et de placement headquarters in Montreal which is also the corpus for a SSHRC (Social Sciences and Humanities Research Council) research grant on Environmental Adaptability in Architecture (Potvin et al. 2003-2007). This case study shows that the technique can prove of great relevance for POEs (Post Occupancy Evaluation) as well as for assistance in a new design project.

summary “Genetic architectures”, not only like a metaphorical name. New materials and new tools give a new architecture. Up to now the human being had to conform with acting only at the superficial level of objects. Now, it’s possible to think further away and descend to actions at the molecular level, influencing on genetic design and on programming chains which are then developed by themselves as artificial computing elements and natural live elements. It’s time to apply all these to architecture, when these can become an integrating part of architecture. These should include an advanced contemporary architecture versus (and basing itself on) the use of the computer as a mere substitute of manual drafts while improving pintoresque ecology: “the new cibernetic-digital architectural design & the new ecological-environmental architectural design”. Not building in the nature, building with the nature, building the nature self. The utopy of today is the reality of tomorrow.

summary Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN The adaptation of the word cyberspace (Gibson, 1984) following the emergence of the World Wide Web Internet not only succinctly revolutionized the correlation of time and space but also poised to challenge how we view the existing spatial concept. This research tries to use protocol analysis to examine text-based cyberspace, such as bulletin board, chart rooms and so forth, and the objective of this research is to realize the spatiality of cyberspace through the cognitive point of view, and to compare the differences of the definitions and perception ways of spatiality between people with general domain and in design fields. Finally, we validate the existence of cyberspace, where the process not only allows further categorization of spatial elements concluded from the earlier study, but discover that varied backgrounds can affect how a user defines and perceives cyberspace (Strate, 1999).

summary Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

title Spatial Forms Generated by Music – The Case Study
source International Conference on Generative Art
summary This paper resulted from the first stage of an ongoing collaborative research between a multi-senses artist (R. T.) from New Zealand and an architect interested in generic architecture (M. D.) from Yugoslavia. The research examines potential relations between music and architecture and explores the ways music could be a source for generation of spatial forms, and vice versa, whether architecture might generate music. In the first stage of the research two different existing generic principles were combined. The graphical interpretation of the music served as a pattern for creating the spatial forms. In this experiment the Brahms’s Hungarian Dance No1 has been used as an initial generator. The music is transformed into the sequence of linear drawings. Every single drawing potentially defines a spatial composition, while each single line represents an axis of the future spatial form. Together with geometric definitions there are some ambient values, like color, transparency and many others, that can be determined by music. After an overview of results, paper concludes with perspectives for future research that will include time as an additional dimension towards generating dynamic spatial concepts based on music.

title Preliminary Concept Design (PCD) Tools for Laboratory Buildings, Automated Design Optimization and Assessment Embedded in Building Information Modeling (BIM) Tools.
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. 451-476.
summary The design of laboratory buildings entails the implementation of a variety of design constraints such as building codes; design guidelines and technical requirements. The application of these requires from designers the derivation of data not explicitly available at early stages of design, at the same time there is no precise methodology to control the consistency, and accuracy of their application. Many of these constraints deal with providing secure environmental conditions for the activities inside laboratories and their repercussions both for the building occupants and population in general, these constraints mandate a strict control over the building’s Mechanical Equipment (MEP), in particular the Heating Ventilating and Air Conditioning (HVAC) system. Due to the importance of these laboratory designers are expected to assess their designs not only according spatial relationships, but also design variables such as HVAC efficiency, air pressure hierarchies, operational costs, and the possible implications of their design decisions in the biological safety of the facility. At this point in time, there are no practical methods for making these assessments, without having constant interaction with HVAC specialists. The assessment of laboratory design variables, particularly those technical in nature, such as dimensioning of ducts or energy consumption are usually performed at late stages of design. They are performed by domain experts using data manually extracted from design information, with the addition of domain specific knowledge, the evaluation is done mostly through manual calculations or building simulations. In traditional practices most expert evaluations are performed once the architectural design have been completed, the turn around of the evaluation might take hours or days depending on the methods used by the engineer, therefore reducing the possibility for design alternatives evaluation. The results of these evaluations will give clues about sizing of the HVAC equipment, and might generate the need for design reformulations, causing higher development costs and time delays. Several efforts in the development of computational tools for automated design evaluation such as wheel chair accessibility (Han, Law, Latombe, Kunz, 2002) security and circulation (Eastman, 2009), and construction codes (ww.Corenet.gov.sg) have demonstrated the capabilities of rule or parameter based building assessment; several computer applications capable of supporting HVAC engineers in system designing for late concept or design development exist, but little has been done to assess the capabilities of computer applications to support laboratory design during architectural Preliminary Concept Design(PCD) (Trcka, Hensen, 2010). Developments in CAD technologies such as Building Information Modeling (BIM) have opened doors to formal explorations in generative design using rule based or parametric modeling [7]. BIM represents buildings as a collection of objects with their own geometry, attributes, and relations. BIM also allows for the definition of objects parametrically including their relation to other model objects. BIM has enabled the development of automated rule based building evaluation (Eastman, 2009). Most of contemporary BIM applications contemplate in their default user interfaces access to design constraints and object attribute manipulations. Some even allow for the application of rules over these. Such capabilities make BIM viable platforms for automation of design data derivation and for the implementation of generative based design assessment. In this paper we analyze the possibilities provided by contemporary BIM for implementing generative based design assessment in laboratory buildings. In this schema, domain specific knowledge is embedded in to the BIM system as to make explicit design metrics that can help designers and engineers to assess the performance of design alternatives. The implementation of generative design assessments during PCD can help designers and engineers to identify design issues early in the process, reducing the number of revisions and reconfigurations in later stages of design. And generally improving design performance.

title Dislocations of the spatial experience: From earthwork to liquid architecture [Deslocamentos da experiência espacial: De earthwork a arquitetura líquida]
source SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 423-427
summary This article reflects about the contemporary notion of “spatial experience” that can be drawn by means of the emergence of the “expanded field” in arts (Rosalind Krauss, 1979). For a perspective view of this notion and for its problematization in the current time we pretend to stablish a counterpoint between two historic moments related to the expansion of the spatial field and its experience: the 1960´s, with the focus on the immanent space by artistic propositions, and nowadays, with the ocurrence of “fusional fields” of art-architecture-landscape-digital media. We adopt as strategy to construct the question, the approximation of two paradigmatic works for their respective epochs: the “earthwork” Spiral Jetty of Robert Smithson, constructed in 1970 in the Great Salt Lake (Utah, USA) and the ephemeral architecture of Blur Building of Elizabeth Diller and Ricardo Scofidio, constructed in 2002 in the Lake Neuchatel, for the Suiss Expo (Yverdon-les-Bains – Suiss).

title Reinterpretation or replacement? The effects of the information and communication technologies on urban space
source CORP 2002, Vienna, pp. 345-349
summary The timid question “Virtual spaces or real places?” forms the core of many debates within the spatial sciences addressing theconsequences of the rapid development of information and communication technologies1 on existing spatial structures. So far several opinions rival each other for the interpretation of current and the prediction of future spatial developments. The spacelessness ofcomputer networks and the possibility to transmit data in real-time have lead visionaries to predict a far-reaching devaluation of timeand space, so questioning the future importance of traditional spatial structures: The “annihilation of distance and time constraints [incomputer networks] could undermine the very rationale for the existence of the city by dissolving the need for physical proximity”(Graham and Marvin 1996: 318). The disappearance of the city into the net, therefore, seems to become a distinct possibility.

title A National Strategy for CAAD and IT-Implementation in the Construction Industry the Construction Industry
doi https://doi.org/10.52842/conf.ecaade.1997.x.o8u
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary The objective of this paper is to present a strategy for implementation of CAD and IT in the construction and building management#1 industry in Sweden. The interest is in how to make the best use of the limited resources in a small country or region, cooperating internationally and at the same time avoiding to be totally dominated by the great international actors in the market of information technology.

In Sweden representatives from the construction and building management industry have put forward a research and development program called: "IT-Bygg#2 2002 - Implementation". It aims at making IT the vehicle for decreasing the building costs and at the same time getting better quality and efficiency out of the industry.

The presented strategy is based on a seminar with some of the most experienced researchers, developers and practitioners of CAD in Sweden. The activities were recorded and annotated, analyzed and put together afterwards.

The proposal in brief is that object oriented distributed CAD is to be used in the long perspective. It will need to be based on international standards such as STEP and it will take at least another 5 years to get established.

Meanwhile something temporary has to be used. Pragmatically a "de facto standard" on formats has to be accepted and implemented. To support new users of IT all software in use in the country will be analyzed, described and published for a national platform for IT-communication within the construction industry.

Finally the question is discussed "How can architect schools then contribute to IT being implemented within the housing sector at a regional or national level?" Some ideas are presented: Creating the good example, better support for the customer, sharing the holistic concept of the project with all actors, taking part in an integrated education process and international collaboration like AVOCAAD and ECAADE.

summary We are convinced that an interactive design process involving engineers and architects will create values to a project. Looking back there have been some obstacles, like a week’s time for exchange of drawings with traditional postal services; manual calculation methods, which could not be spoiled on loose grounds like architect’s sketches; different media – architect’s drawings and engineer’s numbers in tables; attitudes and traditional roles, implemented already in education. Today most of these obstacles can be overcome and we have made a test. We have used ArchiCad by Graphisoft and FEM-design by SKANSKA IT Solutions to test to make an interactive design. Our conclusions are that exchange of information, drawings and other documents is more or less routine in praxis, and it works almost instantly. Computers make calculation faster and easier for the engineer. Though we would wish to have software which manages to do more rapid estimations. Even simulations such as of loads on a structure are practically possible. By using model based CAD the data can be used for transferring quantities for calculations as well as visualization of the design as a platform for collaborate analysis. The technique is developed and usable but to gain acceptance and make use of it is also a matter of attitudes and of application activities in education.

summary This paper explores the juxtaposition between architectonic space and virtual environments. It establishes the hypothesis that the intersection of virtual environments with our common life causes a break-up of time and space. Virtual environments are the last and most integral part of the technological revolution, becoming a parallel world, an unlimited extension of our limited world. The spatial and temporal juxtaposition of these two realities creates a new reality of being “inbetween”, it reveals the “inter-media”. This “inter-media” reality is an issue for architecture of our time, and it still lacks of responses.

title A Java3D Tool for Real-Time Collaboration in a Virtual Reality CAADEnvironment
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary Today the development of network-based virtual communities and the use of avatars have brought a new level of complexity to the meaning of virtuality, providing the technology for remote presence and collaborative experiences. In this project the intention was to pursue this articulated vision of VR in order to assist the design profession during the early stages of the design process. The objective was to provide a tool that is capable of creating 3D shapes in a shared VR environment, thus allowing thedesign and its evolution to be shared. The use of the Java programming language was a natural choice for this project. Because of Java’s performance scalability and hardware independence the concept ofCAAD has been extended, making it possible to create a VR environment that can co-exist between high-end supercomputers and standard PCs. The project is currently being tested using PCs and an SGI system running a Reality Centre. The research reported in this paper describes the architecture and application of software that aims to increase the opportunity for collaboration within virtual worlds and enable effective and transparent information exchange.

title Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source Delft University of Technology
summary The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title The Quantum Matrix:A Three Dimensional Data Integration and Collaboration ToolFor Virtual Environments
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary If a picture is worth a thousand words, what if they could walk and talk? How would you like to bring a whole new dimension to your ideas; to use visualization to convey a sense of time and motion, to use imagery to give your ideas vividness; to use sound to give them voice and view them threedimensionally. The Matrix allows you to do all of this and much more. The Matrix resembles Rubik’s cube, but its purpose is to store, manage and access data of all types and to view them in three dimensions in virtual environments such as the CAVE and on your desktop. The current version can store, access and view almost anything that is in digital form, including:Text files Pictures Video Clips Sound Files Spreadsheets URL’s HTML pages Databases CAD drawings Gantt Charts Business Graphics VRML modelsExecutable Programs OLE (Object Link & Embedded) The Matrix is a three-dimensional multimedia and document management tool. The Matrix anticipates the convergence of electronic media into one consistent environment for analysis and representation. the Matrix uses VMRL and OpenGL technologies to allow the user to be immersed in their data as withCinerama, IMAX and Virtual Reality Environments. The Matrix allows the user to exercise their creativity by interactively placing and organizing their data three dimensionally and navigating through and viewingdata and documents in 3D (monocular and binocular – stereo). The Matrix user interface is simple to use. Employing the now familiar “drag and drop” method to manage data and documents. Items can be placed into the matrix grid at a user selected matrix cube location. Upon dropping a document on a cube it appears as a mapped image onto the surface. Navigating through the 3D Matrix-space is fun. All navigation uses real-time animation giving you instant feed back as to where you are. Data drilling is as simple as mouse click on a Matrix cube. Double clicking the on an object in the matrix activates that object. Data dreams was an image that preexisted the program by several years. The dream was to create a new way oforganizing and exploring data. The Qube image was created using Microstation by Bentley Systems, Inc. The figure was modeled using Poser by MetaCreations and composited using Adobe Photoshop.

title Perceptual Evaluation of the Spatial Manifestations of Urban Structures
source Environmental Simulation - New Impulses in Planning Processes [Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1]
summary The objective of this contribution is to bring to the attention of the community of experts in the field of architectural simulation the interdependence of the spatial manifestations of material components of urban environments and the phenomena of visual perception and imagination which we practically employ in education, professional design and which we also try to use in our contact with the clients. The way towards finding new qualities of urban environments should be dominated by our efforts to understand and perceive the urban structure as a real space-time manifestation, which is being mediated to the user also as a sensually experienced image (scene). Its atmosphere and informative content give impulses for an individualized reaction from various aspects. The content of the experience is multileveled and the sensorial effects of its iconic components can be precisely verified by means of simulation processes in temporal sequences. Taking these aspects as basis, we are developing methods, which would by taking determined conditions into consideration, broaden the spectrum of research, verification, or evaluation of the real spatial manifestations and interactive actions in situ as well as their possible anticipation and performance in laboratory conditions. Perceptual simulation is, together with the significance of experiencing and evaluating the urban environment in the eye-level horizon, a starting point of spatial model simulation methods as a supportive experimental creative and verification tool. The new information technologies and the creative technical cooperation of analog and digital iconic simulation systems create unconventional possibilities for exact recording of information and impulses for the complicated transformational process engaging more actively the community in their participation.

summary The authors have developed an approach to creating real-time audio-visual architectural simulationsthat allow any viewer to virtually explore the spatial and acoustical implications of a building’s design.Though somewhat limited in depth of the immersive experience, this investigation successfullydemonstrated that architectural presentations can be augmented and enriched by incorporating sensoryinformation other than the visual.

title Agent Models of 3D Virtual Worlds

source Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 125-135
summary Architectural design has relevance to the design of virtual worlds that create a sense of place throughthe metaphor of buildings, rooms, and inhabitable spaces. The design and implementation of virtualworlds has focused on the design of 3D form for fast rendering to allow real time exploration of theworld. Using platforms that were originally designed for computer games, some virtual worlds nowcontain preprogrammed interactive behaviors. We present an agent model of virtual worlds in which theobjects in the world have agency, that is, the objects can sense their environment, reason about theirgoals, and make changes to the environment. This agent model is presented and illustrated using a wallagent. Following from the wall agent, we generalize how agency can be attached to any 3D model in avirtual world.

summary The ability to arrange information graphically in digitally represented Cartesian space offers obviousadvantages over two-dimensional graphical reductions. Adding time to the spatial palette provides adynamic dimension. Cartesian space used for these purposes, however, reinforces an ocular-centricapproach to information delivery. We can include sound in order to seek a sensory balance, therebyimproving cognition and enhancing dimensionality within an ‘information space’, especially for complexmaterial requiring greater interactivity or ‘audience’ participation. Combined visual and audio synthesisoffers multidimensional and multi-sensorial environments that challenge existing linear and twodimensionalpresentation orthodoxies – ‘audience’, for instance, presupposes a lecture to be listened to.This paper presents work in progress investigating the use of sonification as both a thematic andnavigational vehicle in dynamic presentation environments.
