title Learning From Mah Jong - Towards a Multi-Agent System that can Recognize Graphic Units
source Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 115-124
summary Sketching is a major means of exploiting the first conceptual developments in architectural design. If we want to support the architect in the ideas-developing phase of design, then we need to understand the conventions of depiction and encoding in drawings. The theory of graphic units provides an extended list of such conventions that are widely used. We propose that a multi-agent system for recognition of graphic units in drawings is fruitful: agents can specialize in graphic units, a multi-agent system can deal with ambiguity through negotiation and conflict resolution, and multi-agent systems function in dynamically changing environments. We first make a multi-agent system that can do something simpler: playing Mah Jong solitary. The Mah Jong solitary system shares the following important features with a multi-agent system that can recognize graphic units: (1) specialized agents for moves; (2) negotiation between agents to establish the best move; (3) dynamically changing environment; and (4) search activity in more advanced strategies. The paper presents the theoretical basis of graphic units and multi-agents systems. The multi-agent framework and its implementation is presented. Various levels of game play are distinguished, and these are correlated to the multi-agent system. The paper shows how the findings form the basis for graphic unit recognition.

title Developing a Building Design Compiler that Frequently evaluates Building Design Performance within the Design Process
source CAADRIA 2003 [Proceedings of the 8th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 974-9584-13-9] Bangkok Thailand 18-20 October 2003, pp. 553-566
summary This paper demonstrates an experience in the development of a design performance evaluation system that can frequently evaluate building design performance within the design process in a real-time manner. The evaluation system, that we call "design compiler," is composed of several modules such as a front-end component-based CAD engine, a knowledge base, and a set of design agents. The notion of the design compiler is quite similar to a compiler for computer programming such as a C compiler. While a computer programmer compiles a set of programming codes to check compiling errors during the implementation of a software system, an architectural designer can 'compile' his/her intermediate design product to evaluate design errors during the design process. The compilation can be done immediately at any level or any time during the design process in a real-time manner. We expect that this compiling process will dramatically increase design feedbacks, and thus result in a better design product. Further research issues that have been identified at the end of the research include increasing the modeling capability, extending to multi-story building representation, developing various design agents, exploring better ways to request and manage design knowledge, and supporting design collaboration.

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 SpaceScope: Spatial Content-Based Retrieval of Architectural Floor Plans
source Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 53-62
summary This research investigates spatial information retrieval in architecture, based on an efficient metadata that is crucial for content-based retrieval. SpaceCore is the metadata schema for spatial information on a floor plan implemented with RDF (Resource Description Framework). To generate metadata, we analyse the factors of spatial information, and then construct a data model containing the content and structure of spatial information. To exploit the metadata, we suggest various query operations with possible predicates and interfaces. SpaceScope, the spatial information retrieval system, consists of three modules: an input data module, a query module, and a browse module. As to implementation, we have already developed the real time plan-structuring system, called “Vitruvius”, as an inputting and modelling data module (using C++). Based on the database, the system performs the similarity analysis and then evaluates the alternative plans with the retrieval goals. At the end of the paper we discuss the potential of SpaceScope in the schematic design stage of the architectural design process, possibly improving and triggering the designer’s conceptual approach against a logical background and facilitate rapid decision-making after full consideration.

title Mass-Customization in the Design of 4,000 Bus Stops
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. 265-278.
summary In Hawaii, ‚"TheBus‚" has been a main transportation system since 1971. Considering the high cost of living in Hawaii and the absence of a rail system, the use of ‚"TheBus‚" has been an instrumental vein of the city life in Honolulu with rhythmical pauses at about 4,000 bus stops in Honolulu. However, existing undifferentiated bus stops are developed from a cost effective mass production system so that they have been problematic for satisfying specific needs from various site conditions. In this research, an integrated computational method of mass-customization for designing 4,000 bus stops is introduced. According to various site conditions, the design of each bus stop is customized. Unlike the mass‚Äêproduced bus stops commonly seen in cities today, the proposed computational method in this paper produces bus stop design outcomes that fit into the physical characteristics of the location in which they are installed. Mass-customization allows for the creation and production of unique or similar buildings and building components, differentiated through digitally‚Äêcontrolled variation (Kolarevic, 2003). The employment of a computational mass‚Äêcustomization in architectural design extends the boundary of design solutions to the satisfaction of multi-objective requirements and unlimited freedom to search alternative solutions (Duarte, 2001; Caldas, 2006). The computational method developed in this paper consists of 1) definition of a prototype, 2) parametric variation, 3) manual deformation, and 4) simulation based deformation. The definition of a prototype is the development of a basic design to be transformed for satisfying various conditions given from a site. In this paper, the bus stop prototype is developed from the analysis of more than 300 bus stops and the categorization of the existing bus stops according to their physical conditions, contextual conditions, climatic conditions, and existing amenities. Based upon the outcome of the analysis, the design variables of a bus stop prototype are defined. Those design variables then guide the basic physical parameters for changing the physical configuration of the prototype according to a given site. From this, many possible design outcomes are generated as instances for further developments. The process of manual deformation is where the designer employs its intuition to develop the selected parametric variation. The designer is compelled to think about the possible implication derived from formal variation. This optional process allows every design decision to have a creative solution from an individual designer with an incidental quality in aesthetics, but substantiated functional quality. Finally the deformation of the selection is guided and controlled by the influence of sun direction/ exposure to the selection. The simulation based deformation starts with the movement of the sun as the trigger for generating the variations of the bus stop prototype. The implementation of the computational method was made within the combination of MEL (Maya Enbedded Language), autodesk MAYA and Ecotect environment.

title Are European cities becoming similar?
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary The paper discusses city specific development patterns to overcome todays transport problems. The results are based on recent andongoing research activities at TUW-IVV and ITS. At previous CORP-conferences, we presented the basics and the development of aplanning support tool to find optimal policy packages in urban transport and land use (Emberger, 1998), (Pfaffenbichler, Emberger, 2001). The core of this planning support tool is a dynamic land use and transport interaction model. This model, which we refer to as Sketch Planning Model (SPM), is embedded into an appraisal and optimisation framework. The SPM and this framework were developed in the recently finished European Union funded research project PROSPECTS1. Case studies with this planning supporttool were performed within PROSPECTS for the cities Edinburgh, Helsinki, Madrid, Oslo, Stockholm and Vienna. These cities are principally comparable in regards of their status (capitals and major business and education centres), but different in their size, population density, transport system etc. A set of policy instruments like public transport improvements, car traffic restrictions, and infrastructure provision was available to formulate strategies to reduce negative impacts of transport and to increase welfare. The overall objective was a sustainable development of the city. Although the instruments and the goals are similar in all investigatedcites, different solutions were adequate. The solutions vary in regard of spatial implementation, implementation time and level of implementation. The paper will highlight some reasons for the different development paths of the cities. As well the comparison of the do nothing scenario as the comparison of the most feasible policy strategies shows that European cities are different, need different solutions for their problems and will stay different in the future.

title Agent support for monitoring collaborative design knowledge
source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 75-82
summary Design teams are typically distributed across many locations and communicate with multiple media. Computer tools have been developed to support and improve such communication. Agent support of design has been discussed in terms of the support of graphical and object based systems. Another aspect of design that is often discounted is the textual dimension. Discussions of media in architectural design typically revolve around graphical forms, be they digital or analogue. This emphasis on graphics overshadows the role of text in design; the interactions of designers requires broader support. In this paper, we consider role of text-agents in support of collaborative architectural design. Text is a common medium to record information in computer technology and has a role to play in an architectural design process. In collaborative environment, a shared understanding and preserved history are important for communication. Design knowledge is accumulated through textual databases, be they email or longer documents. In this way, just as graphics can be seen as a design aid, so too can text. This proof of concept implementation of an agent system demonstrates how collaborative design can benefit from agent support.

summary This research presents the collaboration in the VDS system through a microcomputer technology- a PDA (Personal Digital Assistants). Architect can collaborate anytime anyplace via VDS, a substitution to an old system that requires a specific location to work on. This research has studied and analyzed the format and the limitation of collaboration between PDA and Personal Computer, the wireless communication technology, and the Web Service technology, which enable different devices to share information through the Internet Network. The work process and the studied information have been used to develop a Web Application, a collaboration tool for a team of architect and designer. This Web Application has been tested in a renovation project, a clubhouse for a scuba diving place The objective of this research is to become a guideline of collaboration in architectural design work through Smart Object in order to serve the coming Ubiquitous era (Weiser, 1998)

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.

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.

title MetropoGIS: A City Modeling System
source CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary We report on a new system to generate photo-realistic 3D models of real cities. So far, we focus on the accurate geometric andradiometric modeling of man-made structures. The modeling process starts with a 3D block model obtained from aerial images, aerial laser scans or GIS data. This block model is further augmented with geo-referenced terrestrial images of the facades. Theterrestrial images are either captured using a mobile multi-sensor-platform or an off-the-shelf digital camera. The relative orientationof terrestrial images is calculated automatically and fitted towards the 3D block model with minimized human input using vanishingpoints. 2D image features like lines are extracted from the images and used to model 3D lines using line matching techniques. Theextraction of dense 3D point clouds on the facades is based on a hierarchical point matching strategy over multiple oriented images.Facades are found by robust fitting of plane hypotheses through these 3D line and point clouds. The introduced city modeling systemdelivers a fully 3D geographic information data set and is called MetropoGIS.

source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 29-32
summary Augmented Reality (AR), the layering of reality and virtuality, can be used as a tool in architecture in model scale as well as in 1:1 scale on site. By combining real architecture models with virtual representations like e.g. wind simulation an intensive understanding for impacts can be observed. Coupling AR with further virtual environments (AR and Virtual Reality) in one scenario makes AR a tangible interface for VR and on the other hand supports the group discussion of distributed teams.

summary This paper celebrates the successful outcome of a trial of an innovative multi-platform distributed design decision support system in which the shared design environment exists within the virtual world. The outcome is the result of a sustained three-year research and development effort, within an internationally recognised research group. The project set itself a number of ambitious targets within the broad spectrum of distributed design decision support, viz: • A multi-platform environment: the trial demonstrates inter-operability of different machine platforms - from a home PC to an international standard Virtual Reality Centre. • A distributed environment: the trial demonstrates the high level of understanding amongst the design team separated by time and space. • An ability to propose, discuss and agree upon, design decision from within the virtual world. Hitherto, virtual environments were viewing galleries; designers had to leave them to effect design changes in a conventional CAD package. The trial described in the paper amply demonstrates the potential to design, collaboratively and, in distributed mode, from within the virtual world. The two ideas upon which the system (known as JCAD-VR) is built are: • That all the users present in the virtual world have to be able to share the same virtual environment in a "transparent fashion"; • The user interface, instead of the traditional menu/windows based layout, is part of the virtual world itself. Any element of the interface becomes an object belonging to the 3D world and therefore it is treated as any other object. Each element of the interface can then be moved or scaled according to the user’s needs. The entire project is based on client-server architecture where every user logs into a virtual world and starts sharing design tasks with other users. The authors propose to present a video which demonstrates the positive outcome of the trials to date. More importantly, perhaps, the authors will put the achievements of the R+D into the context of past aspirations and developments in the subject area and, most importantly of all, suggest how these modest achievements will impact on the next decade of increasingly rapid R+D.

summary We are developing an immersive virtual reality system for interior and lighting design where, inside a CAVE(r), one can change at will the color, texture and finishing of all elements in the simulated environment (walls, floor, furniture and decoration) as well as position, type, color and intensity of all light sources. Although the rendering algorithm used in the system is the ray tracing, preliminary results show we are able to achieve almost real time performance. The system is intended to both help architects to better communicate their design ideas to clients through an advanced visualization tool and also speed up the interior and lighting design processes.

summary The sketch is the embodiment of the architectural discussion. It incorporates rapidness and fuzziness and as this it is an object of interpretation. The interesting thing there is the question, if the usage of VR/AR already in the early phases of a design can have an impact for the quality of a design-process. Examples like VRAM (Regenbrecht et al., 2000) or TAP (Seichter et al., 2000) showed that there is a huge potential for research. The sketch as one of the parts of an early design is tightly coupled with cognitive aspects and communication. Pictured by a sketch is just a snapshot of what have to be discussed in the ensuing design procedure. The intention behind this work is an exploration about a medium which is not yet adapted to the digital world (Myers et al., 2000) and it can be easily be described with the words of Harald Innis: Mankind constantly being caught in his own traps: language and systems, developed and most difficult to break down.

summary Navigation is about information that requires visual feedback and spatial orientation in both information representation and userinteraction. Among those, spatial orientation is the primary research question for navigating in 3D information landscape. By inspired by Ware's three control loops, 'spatial metaphors' and 'visual components" are proposed as the fundamental concepts of a navigation framework called 'i-Room'. i-Room is comprised of four constituents-handles, i-Bag, i-Map and Focus/scale. An information landscape based on a repository of diverse digital media of 11 significant civic buildings in Taiwan is designed for testing this navigation framework. An implementation of i-Room based on Muse of navigation realization and their interaction behaviors with spatial metaphors/visual components is also reported in this paper.

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.
