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.

title	Urbamedia - Development of an urban database of fragments of some Argentinian and Latin-American cities using digital technology
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	The proposal of "Urbamedia" is to undertake the development of 3D virtual and interactive models of historical areas of Latin-American cities. The selected zone is the "Mayo Avenue" including the "Mayo Square", an historical place of the city of Buenos Aires, Argentina; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting the first experimental model of the "Mayo Square" that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. combined with a system analysis of urban activities using the “Atlas.ti” CAQDAS software.This particular use of the “Atlas.ti” software is under experimental applications to this type of urban analysis procedures; allowed us the possibility to analysed a set of activities by means of graph theory as result of a series of interviews to the people working in the area. We are also looking to include historical areas of three cities: Mar del Plata, Rosario and Santa Fe (Argentina) and eventually other cities from Latin América as Rio de Janeiro and Habana.Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulations of the environmental parameters.

title	Implicit Handling of Geometric Relations in an Existing Modeler
doi	https://doi.org/10.52842/conf.caadria.2003.613
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. 613-622
summary	This paper presents a constraint-based modeling system, integrated into a widely used CAD modeler. Using a notification mechanism, the system records the precision functions called by the user in order to maintain geometric relations between points locations and source objects. These relations are stored in a directed graph which allows an automatic update of the model.

title	Information Spaces for Mobile City Access
source	International Journal of Architectural Computing vol. 1 - no. 1
summary	This paper describes two complementary European research projects that share common interests and goals.The work described is intended to facilitate city analysis and support decision-making. The first project focuses on the distribution, access and ease of use of city data. The system allows access to historical data concerning key buildings in Liverpool, England, via a suite of web-based tools and a palmtop device. The second project looks at extending the functionality of traditional computer aided design (CAD) software to enable geometric and semantic data to be combined within a single environment. The system allows those involved in city planning to better understand the past and present development pattern of an area so that their decisions on future proposals are better informed.The paper concludes by describing a system that integrates particular aspects of the two projects, and the potential that this integration can bring.This new work provides mobile access to historical city development data, current city information and tools to support urban project development.

source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 659-664
summary	This study describes statue in the early phase of design, the approach taken by its conceptual development and manipulation. And on the developing digital tools provide a computational support for the process of indexing and retrieving. The digital modeling also addresses specifically architectural programming, adjacent relationship between the building element and articulation in designing. The overall in building mass development starting with reasoning of the conceptual model in early phase try to find evocative cases to help designer thinking. And finally discuss some issues and challenges of artificial intelligent. The research for representing designer’s creativity and searching solution provide another way to generate an articulating conceptual model. The integration approach of research starts with the pure case-based and rule-based reasoning system to help designer generate more understandable and creative product in the architectural design application.

title	Developing a Building Design Compiler that Frequently evaluates Building Design Performance within the Design Process
doi	https://doi.org/10.52842/conf.caadria.2003.553
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.

source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	In this paper the conformations, transformations, and mutations developed in the territory of San Juan city, particularly in its Rivadavia shire, due to the developing modeling are analyzed. It includes a series of morphological knowledge on growing styles (continuous and discontinuous), about residential groups and the sense of urban spaces. These studies allow us to formulate design strategies applicable to new complexes, based on programmatic studies that define indicators for typology selection and morphologic development. Those research works were based on comparatives studies of the city before and after the 44's earthquake to the present, involving others knowledge areas and methods and multimedia techniques.

source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, 899 p.
summary	The conference logo is a bird’s eye view of spiral stairs that join and separate – an homage to the famous double spiral staircase in Graz, a tourist attraction of this city and a must-see for any architecturally minded visitor. Carved out of limestone, the medieval construction of the original is a daring feat of masonry as well as a symbolic gesture. The design speaks of separation and reconciliation: The paths of two people that climb the double spiral stairs separate and then meet again at each platform. The relationship between architectural design and the growing digital repertoire of tools and possibilities seems to undergo similar cycles of attraction and rejection: enthusiasm about digital innovations – whether in Virtual Reality, Augmented Reality, Energy Design, Robotic Fabrication, the many Dimensions of BIM or, as right now, in AI and Machine Learning – is typically followed by a certain disillusionment and a realization that the promises were somewhat overblown. But a turn away from these digital innovations can only be temporary. In our call for papers we refer to the first and second ‘digital turns’, a term Mario Carpo coined. Yes, it’s a bit of a pun, but you could indeed see these digital turns in our logo as well. Carpo would probably agree that design and the digital have become inseparably intertwined. While they may be circling in different directions, an innovative rejoinder is always just around the corner. The theme of the conference asked participants to re-consider the relationship between Design and the Digital. The notion of a cycle is already present in the syllable “re”. Indeed, 20 years earlier, in 2003, we held an ECAADE conference in Graz simply under the title “Digital Design” and our re-using – or is it re-cycling? – the theme can be seen as the completion of one of those cycles described above: One level up, we meet again, we’ve come full circle. The question of the relationship between Design and the Digital is still in flux, still worthy of renewed consideration. There is a historical notion implicit in the theme. To reconsider something, one needs to take a step back, to look into the past as well as into the future. Indeed, at this conference we wanted to take a longer view, something not done often enough in the fast-paced world of digital technology. Carefully considering one’s past can be a source of inspiration. In fact, the double spiral stair that inspired our conference logo also inspired many architects through the ages. Konrad Wachsmann, for example, is said to have come up with his famous Grapevine assembly system based on this double spiral stair and its intricate joinery. More recently, Rem Koolhaas deemed the double spiral staircase in Graz important enough to include a detailed model of it in his “elements of architecture” exhibition at the Venice Biennale in 2014. Our interpretation of the stair is a typically digital one, you might say. First of all: it’s a rendering of a virtual model; it only exists inside a computer. Secondly, this virtual model isn’t true to the original. Instead, it does what the digital has made so easy to do: it exaggerates. Where the original has just two spiral stairs that separate and join, our model consists of countless stairs that are joined in this way. We see only a part of the model, but the stairs appear to continue in all directions. The implication is of an endless field of spiral stairs. As the 3D model was generated with a parametric script, it would be very easy to change all parameters of it – including the number of stairs that make it up. Everyone at this conference is familiar with the concept of parametric design: it makes generating models of seemingly endless amounts of connected spiral stairs really easy. Although, of course, if we’re too literal about the term ‘endless’, generating our stair model will eventually crash even the most advanced computers. We know that, too. – That's another truth about the Digital: it makes a promise of infinity, which, in the end, it can’t keep. And even if it could: what’s the point of just adding more of the same: more variations, more options, more possible ways to get lost? Doesn’t the original double spiral staircase contain all those derivatives already? Don’t we know that ‘more’ isn’t necessarily better? In the original double spiral stair the happy end is guaranteed: the lovers’ paths meet at the top as well as when they exit the building. Therefore, the stair is also colloquially known as the Busserlstiege (the kissing stair) or the Versöhnungsstiege (reconciliation stair). In our digitally enhanced version, this outcome is no longer clear: we can choose between multiple directions at each level and we risk losing sight of the one we were with. This is also emblematic of our field of research. eCAADe was founded to promote “good practice and sharing information in relation to the use of computers in research and education in architecture and related professions” (see ecaade.org). That may have seemed a straightforward proposition forty years ago, when the association was founded. A look at the breadth and depth of research topics presented and discussed at this conference (and as a consequence in this book, for which you’re reading the editorial) shows how the field has developed over these forty years. There are sessions on Digital Design Education, on Digital Fabrication, on Virtual Reality, on Virtual Heritage, on Generative Design and Machine Learning, on Digital Cities, on Simulation and Digital Twins, on BIM, on Sustainability, on Circular Design, on Design Theory and on Digital Design Experimentations. We hope you will find what you’re looking for in this book and at the conference – and maybe even more than that: surprising turns and happy encounters between Design and the Digital.

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.

title	A Discursive Grammar for Customizing Mass Housing - The case of Siza´s houses at Malagueira
doi	https://doi.org/10.52842/conf.ecaade.2003.665
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 665-674
summary	The ultimate goal of the described research is a process for mass customizing housing based on computer-aided design and production systems. The current goal is the development of an interactive system for generating solutions on the Web based on a modeling approach called discursive grammar. A discursive grammar consists of a programming grammar and a designing grammar. The programming grammar generates design briefs based on user data; the designing grammar provides the rules for generating designs in a particular style, and a set of heuristics guides the generation of designs towards a solution that matches the design brief. This paper describes the designing grammar using Siza´s houses at Malagueira as a case study.

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	The proposed VLM system intends to facilitate the visual sustainability of urban natural landscape in China. In this system, GIS not only provides technologies for the inventory of landscape characteristics and the visual landscape evaluation, but also contributes to public or professional communication supporting through modeling and visualization. Therefore, GIS holistically acts as a fundamental support in this prototype system. Combining with psychophysical landscape evaluation (LE), photogrammetry and other digital 3D visualization, GIS provides quantitative data, scientific visualization and visual simulation for planning decision making.

title	Monitoring the Dynamics of Informal Settlements in Dar Es Salaam by Remote Sensing: Exploring the Use of Spot, Ers and Small Format Aerial Photography
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	Dar es Salaam is exemplary for cities in the developing world facing an enormous population growth. In the last decades, unplanned settlements have tremendously expanded, causing that around 70 percent of the urban dwellers are living now-a-days in these areas. Tools for monitoring such tremendous growth are relatively weak in developing countries, thus an effective satellite based monitoring system can provide a useful instrument for monitoring the dynamics of urban development. An investigation to asses the ability of extracting reliable information on the expansion and consolidation levels (density) of urban development of the city of Dar es Salaam from SPOT-HRV and ERS-SAR images is described. The use of SPOT and ERS should provide data that is complementary to data derived from the most recent aerial photography and from digital topographic maps. In a series of experiments various classification and fusion techniques are applied to the SPOT-HRV and ERS-SAR data to extract information on building density that is comparable to that obtained from the 1992 data. Ultimately, building density is estimated by linear and non-linear regression models on the basis of an one ha kernel and further aggregation is made to the level of informal settlements for a final analysis. In order to assess the reliability, use is made of several sample areas that are relatively stable over the study period, as well as, of data derived from small format aerial photography. The experiments show a high correlation between the density data derived from the satellite images and the test areas.

title	3D models as a base for historical narrative experiments

summary	Historians have relied mostly in descriptive narratives to represent their research. In the first half of the XX century, with the influence of other disciplines, that instrument started to be questioned. This paper aims to overview that debate and the search for new forms of historical representation that would overcome most of the historians’ alleged shortcomings. A web-based system that relates 3D city models to a database of historical documents of a great variety of sources is presented as a digital alternative for the representation of Rio de Janeiro’s history.

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.

title	Programming Architectural Geometry and CNC: Advancing A Design Paradigm with Mathematical Abstraction
doi	https://doi.org/10.52842/conf.ecaade.2003.337
source	Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 337-342
summary	Direct computer programming of architectural geometry and of CNC tool pathways can control the fabrication of form and the related treatment of material. When the entire form creation and tool path process is taken on as a design problem, there is potentially a closer link between formal design intentions and their physical realization. This paper describes several case studies that engage computer programming as a first stage in an iterative design process coupled with more explicit control over CNC tool paths. It indirectly critiques the design exploration of geometry where there is only user command control over a CAD system and where the specification of CNC pathways is also less explicit. Examples of different strategies are compared in the same educational context.

title	DESIGN AGENTS IN 3D VIRTUALWORLDS
source	IJCAI03 Workshop on Cognitive Modeling of Agents and Multi-Agent Interaction, R Sun (ed), IJCAI, Acapulco, pp 92-100.
summary	Design agents are rational agents that monitor and modify elements of a designed environment. Special characteristics of design agents include the ability to reason about patterns and concepts, and the ability to act autonomously in modifying or changing the design to achieve their own goals. 3D Virtual Worlds are multi-user distributed systems that provide a designed environment and a closed world environment for studying design agents in a multiagent system. We present a model for a design agent reasoning process and a model for constructing a memory of the agent’s knowledge and interaction with a virtual world. The reasoning process includes sensation, perception, conception, hypothesizing, and planning a sequence of actions. Each agent has a constructed memory: a dynamic and changing view of the designed world that is determined by the agents sense data and reasoning. The agents construct and maintain a representation of the relevant objects in the world using a Function- Behavior-Structure formalism in order to reason about the intended and actual functions of the designed objects in the world. We have implemented this agent model by extending the Active Worlds platform so that each object in the 3D world can have agency. We illustrate the model with a door agent and a multi-agent room that reason about the use of the 3D world.
