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.

summary	A method is proposed for architectural construction of virtual spaces by using structures of mnemotechniques. Defined as belonging to the mind, it is proposed to conceive the virtual space through architectural methods by adding the use of Mnemonics, which is the art and technique of developing and strengthening the memory. The memorization process itself becomes central in the process of constructing the virtual context. Introducing examples in history and recent art applications in virtual reality, this paper proposes the introduction of mnemotechniques for the architectural spatial structuring of the virtual space.

title	A Procedural Model for Integrating Physical and Cyberspaces in Architecture
source	Doctoral dissertation, University of Plymouth, Plymouth, U.K
summary	This dissertation articulates opportunities offered by architectural computation, in particular the digital simulation of space known as virtual reality (VR) and its networked, social variant cyberspace. Research suggests that environments that hybridize technologies call for a conception of space as information, i.e. space is both a product of and tool for cognition. The thesis proposes a model whereby architecture can employ this concept of space in creating hybrids that integrate physical and cyberspaces.The dissertation presents important developments in architectural computation that disclose concepts and values that contrast with orthodox practice. Virtual reality and cyberspace, the foci of this inquiry, are seen to embody the more problematic aspects of these developments. They also raise a question of redundancy: If a simulation is good enough, do we still need to build? This question, raised early in the 1990's, is explored through a thought experiment - the Library Paradox - which is assessed and critiqued for its idealistic premises. Still, as technology matures and simulations become more realistic the challenge posed by VR/cyberspace to architecture only becomes more pressing. If the case for virtual idealism seems only to be strengthened by technological and cultural trends, it would seem that a virtual architecture should have been well established in the decade since its introduction.Yet a history of the virtual idealist argument discloses the many difficulties faced by virtual architects. These include differences between idealist and professional practitioners, the failure of technology to achieve its proponents' claims, and confusion over the meaning of virtual architecture among both architects and clients. However, the dissertation also cites the success of virtual architecture in other fields - Human Computer Interface design, digital games, and Computer Supported Collaborative Work - and notes that their adoption of space derives from practice within each discipline. It then proposes that the matter of VR/cyberspace be addressed from within the practice of architecture, a strategy meant to balance the theoretical/academic inclination of previous efforts in this field.The dissertation pursues an assessment that reveals latent, accepted virtualities in design methodologies, instrumentation, and the notations of architectural practices. Of special importance is a spatial database that now pervades the design and construction processes. The unity of this database, effectively a project's cyberspace, and its material counterpart is the subject of the remainder of the dissertation. Such compositions of physical and cyberspaces are herein called cybrids. The dissertation examines current technologies that cybridize architecture and information technology, and proposes their integration within cybrid wholes. The concept of cybrids is articulated in seven principles that are applied in a case study for the design for the Planetary Collegium. The project is presented and critiqued on the basis of these seven principles. The dissertation concludes with a discussion of possible effects of cybrids upon architecture and contemporary culture.

title	Towards Comprehensive Space: A context for the programming/design of cybrids
doi	https://doi.org/10.52842/conf.acadia.2003.161
source	Connecting >> Crossroads of Digital Discourse [Proceedings of the 2003 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-12-8] Indianapolis (Indiana) 24-27 October 2003, pp. 161-171
summary	Cybrids have been presented as mixed realities: spatial, architectural compositions comprised of physical and cyberspaces (Anders 1997). In order to create a rigorous approach to the design of architectural cybrids, this paper offers a model for programming their spaces. Other than accepting cyberspaces as part of architecture’s domain, this approach is not radical. Indeed, many parts of program development resemble those of conventional practice. However, the proposition that cyberspaces should be integrated with material structures requires that their relationship be developed from the outset of a project. Hence, this paper provides a method for their integration from the project’s earliest stages, the establishment of its program. This study for an actual project, the Planetary Collegium, describes a distributed campus comprising buildings and cyberspaces in various locales across the globe. The programming for these cybrids merges them within a comprehensive space consisting not only of the physical and cyberspaces, but also in the cognitive spaces of its designers and users.

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	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	SPOT! Fetch Light - Interactive navigable 3D visualization of direct sunlight
doi	https://doi.org/10.52842/conf.ecaade.2003.117
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 117-124
summary	SPOT is a 3D environment for direct sunlight visualization. Implemented in Java 3D, SPOT features two distinct and complementary components: Time Projection and Navigable Animation for virtual interaction. SPOT supports multi-dimensional data visualization including sun angle variations with diurnal and annual cycles in threedimensional space. In SPOT users can sketch on any surface in the 3D environment to indicate the area for simulation. SPOT then generates a spatial distribution representation of the illuminance level on a selected surface over time, rendered with colors of varied gradients. SPOT also enables designers to visualize the temporal information of light distribution over time for a given point. For each point clicked on the 3D model, SPOT generates a calendar diagram where the X and Y axis represent the months of the year and the time of the day. The color of each cell of the calendar is the result of the calculation of the light amount reaching the selected point.

title	A NEW APPROACH TO VIRTUAL DESIGN FOR SPATIAL CONFIGURATION PROBLEMS,
source	7th IEEE International Information Visualisation Conference, London, UK, 16-17 July 2003. http://www.graphicslink.demon.co.uk/IV03/
summary	In this paper, we present a new framework for the use of Virtual Reality (VR) in engineering design for configuration applications. Traditional VR systems support the visual exploration of a design solution but do not assist the user in exploring alternative solutions based on domain knowledge. Extending previous work in the area of Intelligent Virtual Environment, we propose an intelligent configuration system based on constraint logic programming (CLP), integrated in a real-time 3D graphic environment. This type of integration facilitates the expression of design knowledge in the VE and enables the user to interactively solve and/or refine a spatial configuration problem. In the system described in this paper, the user can visually explore configurations, but his interaction with objects of the configuration problem triggers new cycles of constraint propagation from the modified configuration to produce a new compatible solution.

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	Morphogenetic CA: 69’ 40’ 33 north
source	Proceedings of the Generative Arts conference, Milan, 2003
summary	We would like to present some recent work using cellular automata and agent modelling for the generative design of building configurations. The cellular automata is based on a 3d terrain model of a site (taken from the recent Europan competition) which is encoded with both topological and economic data, and agents that are light sensitive and which reconfigure the developing architecture by checking overshadowing and spatial occupation. The emergent pattern of development therefore results from an understanding of the programmatic and the spatial parameters of the task, and is intimately related to the site and its peculiarities.

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.

title	An empirical approach to the experience of architectural space in VR - Exploring relations between features and affective appraisals of rectangular interiors
doi	https://doi.org/10.52842/conf.ecaade.2003.017
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 17-24
summary	While it is well known that the built environment influences our emotional state, it is often difficult to attribute these experiences to particular properties. In fact, a systematic investigation of the relation between physical structure and emotional experience of architecture has not yet been done. Now virtual reality simulations facilitate a completely controlled variation of spatial properties and thus allow to empirically evaluate architectural hypothesises. The aim of the presented study was to investigate which factors from a component-based description of rooms significantly correlate with cardinal dimensions of experience. In a perceptual experiment experiental qualities of 16 virtual vacant rectangular interiors were rated in eight principal categories by 16 participants using the semantic differential scaling technique. The scenes were generated by a custom made graphics tool that also automatically generated the component-based scene descriptions. The data analysis revealed several interesting correlations between scene features and rated experience: For example, a preference for ratios near to the golden section could be observed for spatial proportions, which are not directly perceivable. Altogether, a set of five independent factors (openness, two room proportions, room area and balustradeheight) appeared to be effective for widely describing the observed variance of the averaged attributed experiental qualities. Our combination of realistic virtual reality simulations and psychophysical data raising methods proved to be effective for basic architectural research. It allowed us to demonstrate quantitative relations between physical properties from a component-based description of architectural space and its emotional experience.

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.

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.

source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The efficient generation of data for 3-D city models and their handling in Spatial Information Systems has become feasible. The derivation of this data from aerial and terrestrial images with semi-automated techniques constitutes the most powerful tool currently available to fulfill this task. Semi-automated object extraction has become a viable concept for the generation of 3-D city models. CyberCity-Modeler (CC-Modeler) has been developed with the aim of creating not only buildings, but also other objects pertaining to a city model efficiently and with a high degree of flexibility concerning the level of detail. In its commercial implementation, CCModeler has been confronted with a number of user requirements which needed to be observed. This led to some extensions in functionality, which are addressed in this paper: Geometrical regularization of buildings, editing functions for topology adjustment, integration of facades and other vertical walls and modeling of overhanging roofs. These extensions of the original concept make CyberCity-Modeler an even more powerful tool for 3-D city modeling.

summary	Natural illumination can be considered as one of the major conditioner of the architectonical project, thus it demands an evaluation of it in the proposed architectonical object. Such evaluation can be achieved with graphic representations produced from computational simulations. However, those representations, images usually, deal with the difficulty to provide a better spatial comprehension since they do not allow people to visualize the tri-dimensional space due to it is a static and bi-dimensional representation. Once the interacting possibility can favour the observer spatial comprehension, this possibility was analyzed, creating a VRML environment to present a natural illumination simulation.

summary	In this research the concept of Solar Envelope has been used to develop a 3D Spatial Design Tool tool, SolCAD, for generating an envelope over a given site based on various design parameters. The solar envelope can be imagined as a container, whose boundaries are derived from the sun’s relative motion. Buildings within this container will not overshadow their surroundings during critical periods of solar access for passive and low-energy architecture. The solar envelope is a space-time construct. Its spatial limits are defined by the parameters of land parcel size, shape, orientation, topography and latitude. It also depends on the time or the period of the time for which it is designed. Its time limits are defined by the hours of each day and the season for which solar access is provided to the land parcel (Knowles 1981). This tool intends to generate an envelope over a site of any shape, size and orientation and for different boundary and height conditions of shadow lines. It is suitable for initial stages of building design process to determine the shape of the building even before the design has been conceptualized.

summary	This paper presents the development of a prototype XMLbased 3D campus map using the 3D VML library. Many universities in the U.S. use two-dimensional (2D) raster image to provide the campus map along with additional building information on their Web site. Research shows that three-dimensional (3D) expression of the 3D objects helps human beings understand the spatial relationship between the objects. Some universities use 3D campus maps to help visitors more intuitively access the building information. However, these 3D campus maps are usually created using raster images. The users cannot change the view point in the 3D campus map for better understanding of the arrangement of the campus. If the users can navigate around in the 3D campus map, they may be able to locate the building of their interest more intuitively. This paper introduces emerging Web technologies that deliver 3D vector graphics on the Web browser over the internet, and the algorithm of the prototype XML-based 3D campus map. Some advantages of using VML in delivering the interactive 3D campus map are also discussed.
