title Digital Design - Research and Practice
source Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1 / Tainan (Taiwan) 13–15 October 2003, 464 p.
summary The use of computers in the design of the built environment has reached a watershed. From peripheral devices in the design process, they have in recent years come to take centre stage. An illustration is immediately at hand. Just as the entries to the competition for the Chicago Tribune Tower in 1922 defined the state-of-the-art at the beginning of the twentieth century, we have a similar marker at the end of the century, the competition in 2002 to replace the World Trade Centre towers in Lower Manhattan offered us a range of architectural solutions that exemplified the state-of-the-art eighty years later, setting forth not only architectural statements but also illustrating clearly the importance of computers in the design of the built environment. In these entries of 2002, we can see that computers have not only become essential to the communication of design but in the investigation and generation of structure, form and composition. The papers in this book are the current state-of-the-art in computer-aided design as it stands in 2003. It is the tenth in a series sponsored by the CAAD Futures Foundation, compiled from papers presented at the biennial CAAD Futures Conferences. As a series, the publications have charted the steady progress in developing the theoretical and practical foundations for applications in design practice. This volume continues in that tradition; thus, this book is entitled Digital Design: Research and Practice. The papers are grouped into three major categories, reflecting thrusts of research and practice, namely: Data and information: its organisation, handling and access, including agents; Virtual worlds: their creation, application and interfaces; and Analysis and creation of form and fabric. The editors received 121 abstracts after the initial call for contributions. From these, 61 abstracts were selected for development into complete papers for further review. From these submissions, 39 papers were chosen for inclusion in this publication. These papers show that the field has evolved from theoretical and development concerns to questions of practice in the decade during which this conference has showcased leading work. Questions of theoretical nature remain as the boundaries of our field expand. As design projects have grasped the potentials of computer-aided design, so have they challenged the capabilities of the tools. Papers here address questions in geometric representation and manipulation (Chiu and Chiu; Kocaturk, Veltkamp and Tuncer), topics that may have been considered to be solved. As design practice becomes increasingly knowledge based, better ways of managing, manipulating and accessing the complex wealth of design information becomes more pressing, demanding continuing research in issues such as modelling (Yang; Wang; Zreik et al), data retrieval and querying (Hwang and Choi; Stouffs and Cumming; Zreik, Stouffs, Tuncer, Ozsariyildiz and Beheshti), new modes of perceiving data (Segers; Tan). Tools are needed to manage, mine and create information for creative work, such as agents (Liew and Gero; Smith; Caneparo and Robiglio; Ding et al) or to support design processes (Smith; Chase). Systems for the support and development of designs continue (Gero; Achten and Jessurun). As progress is made on some fronts, such as user interfaces, attention is again turned to previously research areas such as lighting (Jung, Gross and Do; Ng et al; Wittkopf; Chevier; Glaser, Do and Tai) or services (Garcia; Chen and Lin). In recent years the growth of connectivity has led to a rapid growth in collaborative experience and understanding of the opportunities and issues continues to mature (Jabi; Dave; Zamenopoulos and Alexiou). Increasing interest is given to implications in practice and education (Dave; Oxman; Caneparo, Grassi and Giretti). Topics new to this conference are in the area of design to production or manufacture (Fischer, Burry and Frazer; Shih). Three additional invited papers (Rekimoto; Liu; Kalay) provide clear indication that there is still room to develop new spatial concepts and computer augmented environments for design. In conclusion, we note that these papers represent a good record of the current state of the evolving research in the field of digital design.

title EO-PLAN-GIS Operational earth observation applications involving user communities on national and European level
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The joint GeoVille/ARC Seibersdorf project EO-Plan-GIS has the objective of deriving Earth Observation (EO)/Geographic Information System (GIS) products for public and private customers (i.e. Austrian state governments and digital mapping industry). Representatives of three state administrations (i.e. Carynthia, Upper Austria and Vorarlberg) and of Tele Atlas (a commercial enterprise in the production of digital road databases) have been actively involved in the project activities. The major focus of the project is on the automated differentiation of built-up areas and the derivation of land use/cover data for both the state governments and Tele Atlas, as well as on the update and upgrade of the Tele Atlas road network. Using GIS methods, the EO-derived base data will be adapted to serve the individual user needs (i.e. Geographic State Information Systems and Tele Atlas MultiNet). EO-Plan-GIS was initiated by the Austrian Ministry of Transport, Innovation and Technology as a national initiative within theframework of the current GMES (Global Monitoring for Environment and Security) activities of ESA and the EU. It delivers inputs into the following GMES domains:• European Regional Monitoring, Subtopic A: Land cover change in Europe, characterisation of land cover changes (1950 –2000) in the EU with particular emphasis on landscapes and urban areas.• Horizontal Support Action – Information Management Tools & the Development of a European Spatial Data“Infostructure”.

summary The class of operations known as “undo” has proven to be a valuable addition to most professional work tools. In practice though, its use is frustrating: undo often undoes too much. Its essential informal semantics are that it returns the user to a prior state by recapitulating all intervening states. Why not give the user greater control over which aspects of a design to undo? An alternative is to seek to reuse prior work in any logically-coherent pattern—user input is a precious commodity. The area of generative systems provides insights in a search for alternatives to undo, in particular that prior user and system actions can be changed and reused in new contexts. We contingently introduce a concept we label as design promotions to describe system designs that demonstrate a tight coupling between interactive authorship and system-led generation, that treat past user actions as valuable intentional statements, and that treat alternative user choices as first-class objects of concern. In practice these three properties emphasize reuse. We briefly survey the current state of undo-like operations and potential candidates for implementing design promotions strategies. Through examples, we demonstrate approaches to realizing undo-like operations over specific representations, especially that of constructive solid geometry.

summary This paper describes the concept and the current state of development of a new laboratory for digital experimentation in architectural education and research. The novel forms of collaboration and learning for which it is intended and the quick pace of innovation in digital technology on which it depends both require an appropriately flexible spatial and technological framework. And it requires a particular mindset. The no_LAb__in_feld is not just another laboratory. It is a place, a community, a high-tech construction site, a permanent work in progress. It is the prototype of a next generation design studio.

summary IMLAB (Interdisciplinary Modular Learning System for Architecture and Building Science) is a project, startet by three schools of architecture in Germany: a modular, digital and online-based system, which has the aim to collect and improve teaching elements from architectural schools around the world. The development of digital teaching materials at every single university is very expensive - so the idea is to motivate schools all over the world to contribute their teaching materials and teaching moduls. It could work like an architectural ""napster"". The initial development of this kind of teaching community was funded by the German Federal Ministry of Research as a research project. The momentary state of work is documentated on the following website: www.imlab.de. Unfortunately all the information is in German up to now - we will develop the english version as soon as possible. We do have interactive workshops and design-projects beetween different universities up to now (in Germany) and several contacts to international partners. We would like to use eCAADe 2003 as a platform for multiplying this idea and finding more partners from all over the World.

Online and Global. 3-6 November 2021. edited by B. Bogosian, K. Dörfler, B. Farahi, J. Garcia del Castillo y López, J. Grant, V. Noel, S. Parascho, and J. Scott. 100-109.
doi https://doi.org/10.52842/conf.acadia.2021.100
summary Parasympathy is an interactive spatial experience operating as an extension of visitors’ minds. By integrating Artificial Intelligence (AI), wearable technologies, affective computing (Picard 1995; Picard 2003), and neuroscience, this project blurs the lines between the physical, digital, and biological spheres and empowers users’ brains to solicit positive changes from their spaces based on their real-time biophysical reactions and emotions.

The objective is to deploy these technologies in support of the wellbeing of the community especially when related to social matters such as inclusion and social justice in our built environment. Consequently, this project places the users’ emotions at the very center of its space by performing real-time responses to the emotional state of the individuals within the space.

title CUMINCAD.ES: A First Step Towards Multilingual Digital Libraries in CAAD
source SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary This paper presents developments concerning a digital library called CUMINCAD.ES, which includes CADrelated publications in Spanish language. CUMINCAD is an acronym for Cumulative Index on CAD and in this library only publications in English language are archived. While English may be the lingua franca of scientific communication, publications in other languages is important to strengthen local cultures, invent professional terminology, enable technology transfer to those who are not very proficient in English, such as practitioners and students and to provide an incentive for authors to publish in their native languages. CUMINCAD.ES (http://cumincades.scix.net) is a repository complementing CUMINCAD providing a basis for the investigation of multilingual repositories. As this is work in progress, the state of the art will be reviewed as well as the potential for further developments.

title The VR-Desktop: an Accessible Approach to VR Environments in Teaching and Research
source International Journal of Architectural Computing vol. 1 - no. 2
summary The VR-Desktop initiative is an effort to bring key benefits of projection-based virtual reality into the mainstream of teaching and research at the Pennsylvania State University, through the deployment of comparatively low cost and easy to use virtual reality and integrated multimedia display systems within a variety of contexts. Recent experiences with design and implementation of single- and multi-screen VR systems for teaching and research are described. The systems discussed employ low cost and readily available hardware components, familiar desktop computing environments, and open-source VR development toolkits. The approach is modular and easily adaptable to various applications in research or instruction.

summary This paper intends to combine architecture with state-of-the-art software technologies and operational methods of other domains to free architectural rendering from the restrictions of cold, still graphics or unrealistic computer pictures. The author transforms physical models into digital models through industrial design software, and synthesizes these digital models into motion pictures of the environment via film production software. This way, a designer can effectively turn the ideas of his mind into rough handmade models, instead of spending enormous amounts of time building computer models, and viewers will be able to quickly grasp the conditions of the site through the motion pictures.

title Bridging GIS-based landscape analysis/modelling and 3D-simulation.Is this already 4D?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Several studies have used remote sensing to map patterns of e.g. deforestation or to analyse the rates of land use change. Thesestudies have proven useful for interpreting the causes of urbanization, deforestation etc. and the impact of such changes on theregion. Monitoring of change (e.g. deforestation or reforestation) is frequently perceived as one of the most important contributionsof remote sensing technology to the study of global ecological and environmental change (Roughgarden et al. 1991). Manyresearchers believe that the integration of remote sensing techniques within analysis of environmental change is essential if ecologistsare to meet the challenges of the future, specifically issues relating to global change; however, in practice, this integration has so farbeen limited (Griffiths & Mather 2000). Considerable difficulties are encountered in linking, on the one hand, the biologies oforganisms and the ecologies of populations to the fluxes of material and energy quantifiable at the level of ecosystems. In this paper,we concentrate on the methodological aspects of the delineation of landscape objects and touch the ecological application onlysuperficially but we elucidate the potential of the proposed methodology for several ecological applications briefly.

doi https://doi.org/10.52842/conf.acadia.2007.174
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.

title View from the Road: Environmental Simulation for the Fractal City of Rhine Ruhr
source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 43-47
summary Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

doi https://doi.org/10.52842/conf.caadria.2003.281
summary As light is increasingly perceived as a factor of quality of urban life, it is not surprising that cultural heritage buildings and even civil engineering works are being more and more often illuminated at night. The designers of the projects are revealing a nocturnal vision of the buildings which is often a reflection of the architecture: rhythm, pattern, evenness, symmetry, composition, axes, and so on. The idea of developing a "lighting-modeller" is based upon this assertion. Thus, if we express the needs in terms of functionalities, we can conclude that the hierarchical structure of the architectural edifice can fit in with a "lighting-structure". As a result, concepts like hierarchy, linking, grouping, networking, linearity-polarity, are the basis of the objects and functions that are effective for the great majority of buildings and projects. This "lighting-modeller" can then lead beyond its simulation capabilities to become a design conception tool: hypothesis and variants are quickly realized and tested, and technical data (illumination data, visual comfort) can be obtained as well.

summary Illumination phenomena simulation is important for architectural project design and communication: simulation tools must assist efficiently the designer; results have to be reliable and realistic for the decision-makers. Indeed, it is very difficult, for a nonspecialist to imagine the result of an illumination from the light designer plans. Experience shows that the success of a photo-realistic simulation relies essentially on the choice of the light source characteristics and their correct positioning in the scene. This paper first presents the specificities of illumination projects (very large geometrical data bases enlightened by a large amount of light sources) and the difficulties of their set-up. Light arrangement requires tricky compositions, judicious choices and accurate studies. Currently there is no specific modeller for the handling of light sources as they are considered in radiosity software. Then we present the interactive tool we have developed, named ModLum, in order to set up light sources in a 3D architectural model in order to save time during the design step and simplify the source handling. ModLum specifications and principles are presented. Finally, an application is presented: the illumination project of two cloisters in Quito (Ecuador, South America).

title IMPROVING NEURAL NETWORK MODELS OF PHYSICAL SYSTEMS THROUGH DIMENSIONAL ANALYSIS
source Journal of Applied Soft Computing 2(4): 283-296.
summary The paper presents a technique for generating concise neural network models of physical systems. The neural network models are generated through a two-stage process. The first stage uses information embedded in the dimensions or units in which the data is represented. Dimensional analysis techniques are used initially to make this information explicit, and a limited search in the neural network architecture space is then conducted to determine dimensionless representations of variables/parameters that perform well for a given model complexity. The second stage uses information available in the numerical values of the data to search for high-level dimensionless variables/parameters, generated from simple combinations of dimensionless quantities generated in the first stage and which result in concise neural network models with improved performance characteristics. The search for these high-level dimensionless variables/parameters is conducted in an enhanced representation space using functional link networks with flat or near flat architectures. The use and effectiveness of the technique is demonstrated for three applications. The first is the design and analysis of reinforced concrete beams, which is representative of the class of problems associated with the design and analysis of composites. The second is the classical elastica problem, for predicting non-linear post-buckled behaviour of columns and the third, the analysis of a bent bar under a specified combination of loads.

title XML Technologies and Geodata
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary Photogrammetry and Remote Sensing are very important methods for acquisition of geodata. During the previous decade, severalrevolutionary changes occurred in this area. Until the appearance of automated image analysis tools, it was necessary to measureselected points in the images given. At that time, it was much faster and even cheaper to get images of real world objects compared tothe time and money consuming process of manual analyses. So one tried to minimize this effort by measuring only characteristicpoints such as edges, break-lines, peaks and valleys and, for sure, a grid with a given grid step which was selected to meet the efforts.Lots of information in the images was neglected.Digital point matching algorithms and airborne laser scanning provide many new possibilities. The only restriction on spatialresolution is the one of the used sensors. Given a more precise image sensor, the matching algorithm will be able to match moresurface points; given a higher frequency laser scanner, more points can be measured of the same area. And those sensors get moreand more precise every day. Besides, those techniques allow for fast repetition which is necessary to create time series as a basis for4D modeling! However, this fact is accompanied by several problems concerning the capability of available computers. Some years ago, as the first ideas of 3D city models arose, it was very difficult to acquire the necessary data. Today the new sensors and methods have thenecessary capability, but we are not able to handle the available datasets efficiently, because of shortcomings in the past. In a time ofworld wide data exchange through the internet and global datasets, it is necessary to have efficient methods and algorithms tomanage the available data. There is a need for international, vendor independent data exchange and management standards that haveto be accepted and supported by the industry. This article is going to present several methods of data encoding using standardized data formats based on eXtensible Markup Language (XML). After an introduction to this kind of data encoding, two derived applications for management, storage and presentation of geodata are described. As XML data is written in text format, the datasets have the ability to become rather long.Therefore some promising methods to reduce the amount of data are introduced afterwards. XML documents are mainly used fordata exchange between databases. Therefore the capabilities of commonly used database systems for storage of geodata are describedin the end and current implementation results of the Institute of Photogrammetry and Remote Sensing (I.P.F.) are presented.

summary The course Alternatives of Design is part of an integral viewpoint that aims to prepare architects from the Master Studies Department in Computing in Architecture (LUZ), in two ways: first, by expanding their perspective about potentialities of using new digital technologies in architecture, and second, by qualifying them to apply this acquired theoretical knowledge in their professional environment. The objectives of this paper are to describe the program of this course and to show products (2003), from the introductory to the final presentation of Virtual Museums of Interactive Sculptures, orientated and supervised both at site and at a distance through the Internet. As a result of this experience, a sample was obtained of virtual museums. design and modelling that illustrates what could be understood as virtual architecture with high degree of interaction, looking for the evolution, motivation and teamwork to incorporate virtual reality non-inmersive technologies in this new architectonic approach.
