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.

title	Augmented Reality Aided Design
source	International Journal of Architectural Computing vol. 1 - no. 4
summary	Ten years after Nielsen wrote about the "next generation interface" [1] we are still largely confined to WIMP [2] interfaces in design computing. A big question that lies ahead is 'Does the integration of computing technology through Augmented Reality help the formal design investigation process?' There are several suggestions that the conventional desktop metaphors are counter-intuitive for understanding spatial relationships [1, 3, 4]. Main concern is the mismatch in mapping of presentation and interface. Looking at other research areas, one can see that the application of Augmented Environments (AE) can enhance the speed of decision making [5] or creates better understanding of complex spatial arrangements [6] due to the fact that information is displayed where it occurs. Obviously, the representation and interaction is crucial for perceptive performance in design sketching as it is in AEs. This article will discuss a software prototype called sketchand+ and the implications of Augmented Reality for digital design.

title	Reflections on e-Design: The e-Studio Experience
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	The influence of digital media and information technology on architectural design education and practice is increasingly evident. The practice and learning of architecture is increasingly aided by and dependant on digital media. Digital technologies not only provide new production methods, but also expand our abilities to create, explore, manipulate and compose space. In contemporary design education, there is a continuous demand to deliver new skills in digital media and to rethink architectural design education in the light of the new developments in digital technology. During the academic years 2001-2003, I had the chance to lead the efforts to promote an effective use of digital media for design education at Department of Architecture, Jordan University of Science and Technology (JUST). Architectural curriculum at JUST dedicated much time for teaching computing skills. However, in this curriculum, digital media was taught in the form of "software use" education. In this context, digital media is perceived and used mainly as a presentation tool. Furthermore, Computer Aided Architectural Design and architectural design are taught in separate courses without interactions between the two.

summary	This paper considers transition from physical modelling to digital methods of the creation of architectural forms. Every type of creation has constructed the proper means of expression and its own methodology. The main thesis of this paper is that a specific character of the composition activity of an architect is determined by the modelling methods. As the research on architectural modelling, the two methods of creating spatial architectural forms (cardboard model and computer model) have been compared. Research has been done on the basis of the same exercise for both media. The process of creation proceeded in the same way, too. As the start point students have found the inspiration. Each student presented photos of existing architectural objects and a text, which explained the reasons of the choice. Next steps were sketches of the idea and realisation of the model. The achieved results of creative activity fully confirm the thesis of the research.

title	The Geographical Alpine Information System “Galpis” in the Raumalp Project. Outlay and Output
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	RAUMALP, an interdisciplinary research project of the Austrian Academy of Sciences, shall examine problem areas of spatial development on community level in the Austrian alpine region. The aim is the investigation of scientific basics for political decision finding, especially for the regional-specific realisation of the Alpine Convention. All ascertained information shall be included in “GALPIS”, a comprehensive Alpine Space Information System. GALPIS based on ESRI ArcGIS and MS Access software works with data from different sources, like ISIS, the electronic data base of Statistic Austria, and original data and maps gathered and elaborated by the working groups of RAUMALP. This also includes ecological raster data. Dealing with administrative units, „real“ space and raster space, RAUMALP will integrate the different space levels mostly to administrative spatial units representing the existing 1145 communities of the RAUMALP study area. This will be realised by overlay of grids, types of land use and communitypolygons. Major task of GALPIS is a conversion of former communal data (p. e. 1451 communities in 1951) that should represent the recent administrative boundaries. By this way it is possible to make thematic and time-integrative analyses of community data. GIS modelling of the six case studies is more complex. The conceptual model has to integrate several vector and raster layers such as land plots (“Digitale Katastralmappe”), types of land use (“Land Use and Land Cover Austria” by M. Seger) and biodiversity. P. e., the working group settlement is using a logical data model based on the entity “building” with the attributes “construction”,“function”, etc.

title	Shape Generation Using Pareto Genetic Algorithms: Integrating Conflicting Design Objectives in Low-Energy Architecture
source	International Journal of Architectural Computing vol. 1 - no. 4
summary	The Generative Design System [GDS] presented in this paper was developed to assist designers in researching low-energy architecture solutions. The GDS has the capability to evolve architectural forms that are energy-efficient, while complying to design intentions expressed by the architect and responding to conflicting objectives. To achieve this evolutionary development, the system integrates a search and optimization method [Genetic Algorithm], building energy simulation software [DOE2.1E], and Pareto multicriteria optimization techniques. The GDS adaptively generates populations of alternative solutions, from an initial schematic layout and a set of rules and constraints designed by the architect to encode design intentions. The two conflicting objective functions considered in this paper are maximizing daylighting use and minimizing energy consumption for conditioning the building. The GDS generated an uniformly sampled, continuous Pareto front, from which six points were visualized in terms of the proposed architectural solutions.

title	Spatial Cognition in Digital Cities
source	International Journal of Architectural Computing vol. 1 - no. 4
summary	Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. However, there are questions as to how to enter the new emerging digital cities, how humans perceive themselves in digital cities, and there are also issues of recognition of the digital city forms? This paper takes the idea of cognition in order to explore the structure of the new spatiality as cyberspace. By exploring the factors relating to human spatial cognition in physical space it is possible to interpret how humans perceive the spatial form of digital cities. By examining spatial experience in physical space, the interface of spatial cognition of interaction between digital cities and physical cities can be investigated. And by taking this approach, we propose an online prototype of a metaphor for a digital city.

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	AN INCLUSIVE ‘WORK-METHOD’ AND A SPECIFIC SEARCH FOR FULLY SUPPORTED SOLUTIONS THROUGH SUBJECTORIENTED DESIGN (INSTEAD OF OBJECT-ORIENTED)!
source	LOCAL VALUES in a NETWORKED DESIGN WORLD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Stellingwerff, Martijn and Verbeke, Johan (Eds.), (2004) DUP Science - Delft University Press, ISBN 90-407-2507-1.
summary	This paper talks about the hardness of CAAD.And it talks about the necessity to develop ‘soft’ CAAD.A lot of architectural adventures are stopped in the beginning or the middle of the road. Because of decisions far away from the designers or the clients. These decisions break in against some aspects of the design. Small details often kill a whole design-process.Does architectural design only belong to architects and planners ?To a “Me, myself and I”-world ? For the last 10 years, we have gained a lot of experience of designing architectural landscapes in a specific way. We design in such a way that developing projects can change or evolve strongly within themselves without losing their typical spirit. Change because of external and non-predictable events, change because of unexpected or changing circumstances, change because of the participation of new intervening people….New housing projects in Apeldoorn and Dordrecht,Rehabilitation projects in Gennevilliers (Paris) and Hellersdorf (Berlin), …Schools and hospitals in Amsterdam, …Each time very local aspects are incorporated in the different design-spirits.The networks are similar because of specific design-methods.This paper wants to explain something about this process-spirit.

title	Internet based support for architectural planning processes
source	International Journal of Architectural Computing vol. 1 - no. 3
summary	As building projects become increasingly more complex, the number of project participants grows as does their spatial distribution. An effective decentralised work process and co-operation is of increasing importance. The global computer network, the internet, has great potential and recent times have seen the development of a variety of techniques in this field. The project described here is based upon this approach and also takes it a step further. A specific analysis of the topic and the subsequent identification of potential approaches formed the basis for an architectural application that brings the architect in contact with other project participants using the internet as a powerful yet simple and easy to use medium.

title	Erfahrungen und Erfolge bei der Umsetzung von RAPIS - Raum- und Projektinformationssystem für die Vienna Region [Experience and Results with the RAPS-System for the Viennese Region]
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	In shortest terms: RAPIS is a metadatabase on spatial information in the “Vienna Region”. More interesting then this simple fact is the way how theproject was implemented and what the effects on regional development are.RAPIS is the acronym for “Regional Planning and Project Information System for the Vienna Region” and was implemented as the Austrian part of the Interreg IIc Project IM-PLAN (Implementation of models for co-operative planning in metropolitan regions). The aim was to create aninformation platform for planning relevant information for the whole region, integrating existing data sources from federal and state administrationas well as private companies. RAPIS enables an overview of the available spatial datasets in the "Vienna Region " and focuses on the following questions: Which datasets relevant for planning and development are available within the region? Who can use these datasets under which conditions? Which plans and projects do exist for the region? In addition also metainformation on the most important international data sources was collected as well as information to projects and plans with regional and trans-regional impacts. During the implementation great importance was given to communication and sensitisation for the importance the topic: geo-informationinfrastructre as a key ressource for spatial development and regional co-operation. It showed up that Austria and the "Vienna Region" have a very good initial position and excellent databases on national, state, local and international level. However, it seems that almost everything exists already but hardly anybody knows about it ... – potential users do not know what data and information already exists and how to get and use it. Intensive communication, information and permanent discussion of the topic „(Geo-) Information“ within the „planners community“ carried the topic into the public and strengthened the consciousness for the importance of information-infrastructure for regional co-operation.

summary	As a couple of years ago the use of computers slowly entered studios of architecture, the development of operating systems actually enables everybody to control even bigger networks within studios or offices. Recently these local networks started to get networked themselves. Interactions between local design partners involve a large variety of problems• different CAD-systems• different versions of the same CAD-system• different methods of transfer• different security ideas• different levels of technical knowledge In the course of extension to a global level these problems in the first approach have been growing dramatically, involving additionally language and mentality problems. But in the outcome the exchange of documents and ideas improves in speed, quality and accuracy or this will at least happen in the near future.Global networking offers a great challenge, we have to give this matter a big deal of efforts to earn the values and results, which may be achieved.

summary	Recent years have seen the steady increase of automated kiosks and temporary structures that begin to replace traditional building types. In this course we studied and analyzed the development of the gazebo/kiosk in urban/rural settings both inside and outside over time, assessed its value for commerce and social equity, proposed a forward projection regarding the role digital info-booths/commercial kiosks will play in our urban environment, and developed new spatial models that can become an integral part of our daily experience.

summary	The problems of storage of local cultural heritage in digital databases, are reported in the paper. An exemplar case of RuralXML framework is presented. Three main groups of challenges relating to “culturally rich” databases are recognised:1. Estimation of the significance of digital databases for supporting design process, educational needs and scientific investigations;2. The conceptual problems with digital representation of “the paper heritage”3. The technical problems related to the architectural databases.The most important aspects of the problem are mentioned, as a background to a discussion about the reciprocal dependencies between technology and local values, i.e. how technology supports acting with the local architectural heritage, and how “cultural significance” values technology. We claim that digital technology not only enables storage and management of such data, but it also adds a new dimension to the design, making it “locally-sensitive” and oriented towards context by means of employing digitally archived architectural data. The accessibility to information about the “local” architecture heritage is important for local as well as global design. The premises for such statements, are presented.

summary	Cyberspace is quickly becoming an alternative ‘place’ for everyday economic, cultural, and other human activities. It ought, therefore, to be designed according to the principles, theories, experiences, and practices that have been guiding physical placemaking for thousands of years, rather than the woefully inadequate metaphor of the printed page. 3D Cyber-places must embrace the essential characteristics that make a ‘place’ in physical space, while at the same time take advantage of the opportunities offered by Cyberspace. By looking at physical architecture as a case study and metaphor for organizing space into meaningful places, this paper discusses the possibility of organizing Cyberspace into spatial settings that, like physical places, afford social interaction and embody cultural values.

summary	In recent years Dutch secondary education has been undergoing a fundamental change due to the introduction of new didactic approaches which relate strongly to ongoing social and technological developments. This affects existing school buildings, the majority of which is quite conventional in spatial terms and is characterized by limited flexibility and transformability. Consequently, most schools require extensive modifications in their spatial and building structure. The requirements underlying these modifications are not stable. Many schools have become interested in experimental ideas that may require inevitably further changes in the buildings. The paper considers the continuous transformation of Dutch school buildings with respect to their typology: by correlating new design briefs to building types rather than their instances we arrive at general guidelines that can be easily adapted to specific cases. To achieve this, the types are analysed with respect to geometry, topology and zoning. The results of the analysis describe the affordances of each type in terms of general flexibility, transformability and adaptability, as well as in relation to generic briefs. They also provide an explanation of the historical evolution of the types and the means for relating primary characteristics to local configurations, thereby allowing the accurate description of hybrid instances. The descriptions and analysis of buildings are organized into a polyhierarchical multilevel database that supports typological abstraction and offers several starting points (at various abstraction levels) for matching a new brief to an existing building. This enriches the development of the brief or a design solution with explicit, specific information derived from concrete precedents with known form, structure, behaviour and performance.

title	Space, Place and Digital Media:Towards a Better Simulation of a City that has now Disappeared
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	Digital media enable researchers and designers to derive better informed processes in solving problems of historical architectural restoration and virtual archaeology. However, recently insufficiencies have been found in the main technologies often applied in such techniques, such as 3D modeling, high-quality rendering and animation. Given these problems, this paper attempts to explore a digital reconstruction procedure for historical architecture and cities using 3D scanning, Virtual Reality cave technology and motion capture technology. This case study is based on a collaborative project in conjunction with the National Palace Museum, Taiwan, and the China Times, Taiwan.The five steps involved in this project include data collection and analysis, three-dimensional digital inferences, digital reconstruction of static and moving models, scenario dynamics (by integrating the two kinds of models), and visual-spatial immersion using a VR-cave representation. Finally, a preliminary digital reconstruction procedure is presented.

summary	Working with big models requires a good balance between the technical requirements of the model and the technical requirements of the user. Although every virtual model, whether it is 2d, 3d or 4d, may be regarded as a particular form of a general data base, it is clear that is not, at the present time, a very flexible data base. It does not behave like a relational data base that can be inspected in a flexible way. On the contrary, it has a rigid structure, a hierarchical structure that is well suited for performance but is badly suited for navigating through the data and gathering derived information. These are well known disadvantages and advantages, related to the evolution of the data base software that has moved, in the last 30 years, from a hierarchical to a relational structure. These considerations are relevant for any kind of architectural or engineering model. But are particularly pertinent in the case of the model of a city where everything must have its place, and should relate properly with other parts of the model, be susceptible of further modifications and be able to receive new information. These and other related issues have been encountered and developed during the construction of several models at our Laboratory at the ETS Architecture of Barcelona. Our paper explains the main decisions we had to take during the course of these works with special emphasis on those aspects related with the organization of different kind of data in a unified whole that had to be sent to other professionals and had to be, for that reason, organized in a clear and comprehensible way for its further development.

As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

summary	This study focuses on the problem of how to structure spatial and component based building data with the intention to use it in the simulation and analysis of the performance of buildings. Special attention was paid to the interoperability and optimization of the resulting data files.The study builds its investigation onto XML (Extensible Markup Language) data modeling framework.The authors have studied different ways of arranging building information in XML format for effective data storage and have developed a data modeling framework called bmXML for buildings. Initial results are two-fold: a VBA application was developed to create the appropriate building model in AutoCAD with the intention to write building data in bmXML format, and a JAVA application to view the file thus created.This paper primarily focuses on the former, i.e. the AutoCAD application and the bmXML format.
