title	A 3D Model of the Inner City of Beijing

summary	This study has two major concentrations: 1) exploring methods of creating a digital city model, and 2) applying the model to study urban spatial structure, an issue of particular interest and importance to urban planners. Based on existing studies that primarily address two-dimensional (2D) urban structure, this paper focuses on the three-dimensional (3D) structure relating to the 3D urban form. Given their greater clarity and possibilities for quantitative analysis, both 3D digital urban models and GIS spatial overlay analysis methods hold tremendous potential for analysing and predicting future urban form. In this project, the Xidan Business District in Beijing's Inner City was the area selected to implement the digital-city application. Under the hypothesis that the existing urban spatial structure is determined by the city's urban planning scheme and current urban marketing forces, it is found that actual urban development does not follow the planning restrictions on zoning and building height regulations. Some contradictions and conflicts, such as building location and height, appeared in the studied district. The specific reasons for the discrepancies need to be further studied.

title	Visualisation of Martyr’s Square, Beirut
source	CONVR2005 5th Conference of Construction Applications of Virtual Reality, ADETTI/ISCTE, Durham, UK, 12-13 September 2005
summary	Solidere, a Lebanese joint-stock company, was created by government decree in 1994 to reconstruct Beirut city-centre. The company, a form of public-private partnership, has a majority share holding of former owners and tenants of city-centre property. Several projects are underway, including the redevelopment of Place des Martyrs, once the bustling heart of Beirut but badly damaged during the war. Urban planners in Beirut have recently developed a 3D computer model to visually describe the spatial characteristics of Martyr’s Square and its context, prior to inviting design proposals for an international competition. This paper describes issues pertaining to the development of the model to meet the needs of urban designers and town planners. It also considers potential future uses of the simulation, outlining areas for further research and development.

summary	This paper describes how urban planners in Beirut are applying three-dimensional computer modelling to aid design decision making in the regeneration programme for the city. The study reports on the recent developments of a computer model of Beirut and its effectiveness in communicating the spatial characteristics of Martyr’s Square, a place of historic significance in the city. An international urban design competition for Martyr’s Square, and its new axis to the sea, is underway to identify new ideas for the development of this area. This paper reports on the process of creating the computer model and feedback from users. It considers future plans for further 3D modelling of the city centre to meet the needs of urban designers.

title	From CAD to VR – Implementations for Urban Planning and Building Design
doi	https://doi.org/10.52842/conf.ecaade.2005.399

summary	At present time, three-dimensional objects are often represented with 2D-data in urban planning and building design. In order to get all the involved parties to fully understand a certain project, this may not be enough. More and more projects therefore take use of the Virtual Reality (VR) technique as a complement to traditional 2D drawings and sketches. All the involved parties can then share a common frame of reference for all discussions regarding a certain project. Unfortunately, the technique is not yet adapted to fit the current building design process. In this paper, we present a solution for semi-automatic generation of a VR-model based on 3D CAD information and aerial photos obtained from the City Planning Authorities in Sweden. The data is imported to support real-time editing of terrain, roads and buildings. We also present a framework for importing 3D-models created in Autodesk Revit which enables a seamless integration of modern 3D CAD and VR-models. The features are implemented in a software developed at Chalmers Visualization studio (Gothenburg, Sweden) and technical details about terrain handling and speed-up techniques will be given.

title	Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary	The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

title	A 3D, interactive, multilayered, web-enabled model as a tool for multiple sets of end user groups: A case study and end user analysis
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 392-396
summary	This research undertakes a case study involving focus groups of potential end users, to identify how a successful digital tool could be created using new and emerging technologies, to accommodate the multiple needs of these end users. 2005 saw the completion of a research paper, which proposed that a single, 3 dimensional digital model of a city forming a core for many different information systems, is a better approach to the needs of the city than many individual models optimised for each information system. The case for the single 3D model was evaluated through the research, development, delivery and analysis of a prototype 3 Dimensional model of Wellington City, New Zealand, presenting different ‘views’ of information in Wellington: a rendered visualisation in an animated “walkthrough”; the impact of planning constraints on daylight; interactive “plots” of property values. The development and delivery of the prototype model was analysed in regards to how complex, costly and time consuming it may be to exploit one base model for several purposes; and also therefore how beneficial, affordable and potentially successful a single model may be. The prototype model was created to test the idea, and therefore provided conclusions based on a limited feasibility analysis - with four potential information layers modelled and two potential delivery methods tested. The prototype model and user analysis results were presented in a research report that suggested further research and development of a single model could be very beneficial: Positive feedback from potential end users and data providers, and examples of potential data mining opportunities forming the basis of the need for continued research. 2006 sees the research continue as an 18 month research project in conjunction with an industry partner, Terralink International, (http://www.terralink.co.nz/). Terralink International Limited provides GIS and mapping solutions which according to their web site: “enable better business management.” The company maintains a national resource of “imagery, cartography, and spatial databases” and provides consultancy services linking these to company databases through GIS systems. The research investigates the potential for 3 dimensional, interactive, multilayered models to enhance delivery of information to multiple end user groups. The research method uses functional prototypes in end-user focus group workshops. These workshops, consisting of a combination of presentations, hands on interactive examples, group discussions, and individual feedback surveys, aim to establish how a tool might best be developed to communicate to a wide range of end users. The means of delivery whether a stand alone tool or web-based is a key element of the user group workshop assessment process. Note: The submission of the prototype tool (via video or interactive media) would greatly increase the effectiveness of the research presentation. Ability to include such media would be greatly appreciated.

title	The Effect of Stereovision on the Experience of VR Models of the External Surroundings and the Interior of a Building
doi	https://doi.org/10.52842/conf.ecaade.2005.391
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 391-398
summary	Virtual reality offers considerable promise with regard to facilitating the building process. A good example is the facilitation of communication between architects and building companies, sellers and buyers or between community planners and the general public. It is often thought that in order to utilise the potential of VR in, for example, the above-mentioned contexts, it is necessary to use fully fledged versions of VR, including stereovision and the possibility of controlling the VR show. However, if a model can also be presented on less advanced equipment and still interpreted in a way that is useful to the viewer it will be possible to distribute the model simply and effectively. This would make it easier to create a more democratic urban planning process compared with if specialised equipment needed to be used and special shows needed to be arranged. In this study we compared the experience of two VR models (a large indoor exhibition hall and an outdoor street in Gothenburg, Sweden) when presented with and without stereovision. When the experience was measured using the Semantic Environmental Scale (the SMB scale, developed by Küller, 1975, 1991), questions on the experience of presence and six other questions on the experience of the models, the results only revealed one indication that stereovision made a difference. This indication was the result for the SMB factor Enclosedness. Suggestions are presented for future research in this area.

title	Spatio-Temporally Navigable Representation and Communication of Urban Cultural Heritage
source	Proceedings: VSMM 2005 International Conference on Virtual Systems and Multimedia
summary	Virtual environments are effective tools for the representation and communication of cultural heritage. We suggest that an interactive, immersive and dynamic navigation of the virtual representation of the urban environment will not only convey the essence of the culture and the changes it underwent in a more comprehensible manner, but will engender a 'sense of place'—genius loci— in the visitors. This cognitive mode will help them learn about much more than the geometry and materiality of the city: it will make them 'feel' part of the event itself. By presenting a socially shareable experience, we aim to introduce the medium the character of a genuine place, and make it a social venue for active exploration, discussion and interaction. Virtual reality surpasses both traditional media and 3D-models and offers what they cannot. The affordances of the medium, however, also have the potential to destroy the sense of place it strives to engender. It can do so by allowing a kind of ‘time travel,’ to different periods in the history of the site. This ability locates visitors not only spatially, but also temporally. Everyday experience helps us understand the meaning of spatial boundedness, but does not prepare us to deal with temporal boundedness: sensing the presence of fellow visitors at different times. In this paper we describe our experiences in producing spatio-temporally navigable virtual reconstructions of two distinct culturally significant historic sites: the neolithic village of Çatalhöyük, and the medieval city of Cairo. We demonstrate the use of spatio-temporal navigation through a dynamic, chronologically layered model that can be browsed by multiple users at the same time. Such a dynamic system for representing chronological architectural events requires the extension of our conception of place into the temporal domain. We introduce a new concept, temporal field of view (t-FOV) and discuss how it can aid us in resolving an intrinsic challenge introduced by the representation of the temporal dimension in virtual environments.

title	Architecture as Drawing, Perception and Cognition
doi	https://doi.org/10.52842/conf.ecaade.2005.083
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 83-90
summary	This work is about realizing that human perception is inherent to architecture. It is an asset and a trait subject to training and development in an empirical way, involving physical and manual action. It cannot be taught literally through convention and logic reasoning. It is a human achievement of great significance built on intellectual and scientific knowledge. It is something, being physical and empirical, that is supported on instrumental procedure. The computer, as a machine and an instrument, does not shorten the empirical experience of manipulation; on the contrary, it enhances J.J. Gibson’s findings about the perception of space in relation to eye and body movement. Being a cybernetic machine the computer may, and shall, evolve, and become perceptive. In order for that to happen, it is important to keep in mind the mechanism of human perception. Through producing a computerized model of a major architectural work, we develop natural knowledge about its physical features and the thought that lies underneath. To be able to use the computer as an instrument provides a user with explicit knowledge about its ways and mechanism that has to be made available. It involves training, which is to a great extent self-explanatory, and also explicit knowledge about the conventions that are being used, such as programming, reasoning and trigonometry.

title	The Impact of 3D Digital Modeling on the 3D Design Aspects in Urban Design Plans
doi	https://doi.org/10.52842/conf.ecaade.2005.331
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 331-340
summary	Some experts suggest that urban design plans in US cities may lack adequate coverage of the three-dimensional design aspects of the built environment. 3D digital models may help designers visualize and interact with design alternatives, large urban data sets, and 3D information more effectively, thus correcting this problem. Case studies of recent urban design plans that have used 3D digital models may indicate whether these technologies can increase the quality of the plan. This research discusses the role 3D urban models can play in supporting designers in addressing the 3D design aspects. A literature review focused on reviewing secondary sources to construct or adopt theoretical propositions against which the empirical data can be compared and contrasted. A case study involved investigating the methods with which 3D models have been used in developing a selected urban design plan. The content analysis of the case study refuted the premise that the plan would inadequately address 3D aspects and utilize 3D information, and indicated an effective usage of 3D modeling to analyze and represent most of the 3D and 2D information elements and issues. The results are consistent with a hypothesis that the effective usage of 3D modeling would result in the effective coverage of 3D information and issues. The effective usage of the model’s functionalities has improved the quality of the decision-making process through improving designers’ cognitive capabilities and providing a platform for communicating design ideas among and across design teams.

title	Digital Historic Heritage: documenting of Pelourinho, Salvador - Bahia, Brazil, with 3D laser scanning technology
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 673-678
summary	This paper describes the Pelourinho Project realized past July in Salvador, during the 1st International Conference on 3D Laser Scanning for Heritage Documentation. The Pelourinho located at the historic center of Salvador, is an impressive wide set of buildings listed by UNESCO as World Heritage. The text contains a quickly overview about the 3D laser scanning technology, shows how data are captured and what they stored and what they means. The 3D laser scanning model, another kind of 3D geometric model is called point cloud and represents an excellent way to store data of some particular constructions. Because its irregular shapes it is very arduous to survey and represent these constructions by any other method. The point cloud model is an excellent way to represent with integrity and accuracy these particular complex shapes like the colonial baroque churches in Brazil. [Full paper in Portuguese]

title	A Representation Language for a Prototype CAD Tool for Intelligent Rooms
doi	https://doi.org/10.52842/conf.acadia.2005.170
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 170-183
summary	Intelligent rooms are a type of intelligent environment which enhance ordinary activities within the confines of a room by responding to human interaction using pervasive and ubiquitous computing. In the design of intelligent rooms, the specification of how the intelligent room enacts intelligent behavior through computational means is as integral as the geometric description. The self-aware and context-aware capabilities of intelligent rooms extend the requirements for computer-aided design tools beyond 3D modeling of objects. This article presents a Hardware as Agents Description Language for Intelligent Rooms (HADLIR) to model hardware in an intelligent room as “hardware agents” having sensor and/or effector modalities with rules and goals. End-users describe intelligent room hardware as agents based on the HADLIR representation and write agent rules and goals in Jess for each hardware component. This HADLIR agent description and the requisite software sensors/effectors constitute “hardware agents” which are instantiated into a multi-agent society software environment. The society is then bridged to either a virtual environment to prototype the intelligent room or to microelectronic controllers to implement a physical intelligent room. The integration illustrates how the HADLIR representation assists in the design, simulation and implementation of an intelligent room and provides a foundation technology for CAD tools for the creation of intelligent rooms.

summary	This paper describes the progress of a multi-disciplinary team from Texas A&M University to digitally document the command post at one of the most significant historic sites of the D-Day landings: Pointe du Hoc. The methods used to collect survey data for both the production of 2D Historic American Building Survey drawings and for the 3D digital model are described. The processes used to produce the 3D digital model involves collecting survey data using digital photogrammetry and then applying surfaces to that model using modeling software. The results of the first season’s survey work are described and illustrated. Finally, the problems encountered with lighting and the digital photogrammetry processing are discussed and recommendations made for future work.

summary	This paper presents the advancements of the Urbamedia project which was designed as part of a research program at the Center CAO (Creation computer assist), School of Architectural Design and Urbanism, University of Buenos Aires, which was led by the valued master and advisory professor Architect Arturo F. Montagu. This proposal of the city of Buenos Aires on the Mayo Avenue expands the original historical fragment presented between the following two referenced representative landmarks: The Two Congresses Square and the Mayo Square. It continues with the advancement of methodologies and techniques implemented in a system of “integrated visualization and communication” for the development of a VRML (Virtual Reality Modeling Language) 3D virtual non-immersive and interactive vision. It also incorporates the development of a “foundation of digitally integrated knowledge” with fragments of central areas from other surrounding cities as well as interfaced phenomenological situations. The application of digital VRML technology has allowed for thoroughly researching the processes through dynamic simulation of specific urban fragments (Mayo Avenue within Buenos Aires) and the cities that are also participating in the project.

title	Navigating towards digital tectonic tools
doi	https://doi.org/10.52842/conf.acadia.2005.114
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 114-127
summary	The computer holds a great potential to break down the barriers between architecture and the technical aspects relating to architecture, thus supporting innovative architecture with an inner correspondence between form and technique. While the differing values in architecture and technique can seem like opposites, the term tectonics deals with creating a meaningful relationship between the two. The aim of this paper is to investigate what a digital tectonic tool could be and what relationship with technology it should represent. An understanding of this relationship can help us not only to understand the conflicts in architecture and the building industry but also bring us further into a discussion of how architecture can use digital tools. The investigation is carried out firstly by approaching the subject theoretically through the term tectonics and by setting up a model of the values a tectonic tool should encompass. Secondly the ability and validity of the model are shown by applying it to a case study of Jørn Utzon’s work on Minor Hall in Sydney Opera House - for the sake of exemplification the technical field focused on in this paper is room acoustics. Thirdly the relationship between the model of tectonics and the case will be compared and lastly a discussion about the characteristics of a tectonic tool and its implications on digital tectonic tools will be carried out.

summary	The central feature of the project is the development of a computer and its interfaces to simulate urban space and, in the context of an intermedia city tour, to allow citizens to creatively influence their urban space by manipulating media structures at chosen points throughout the city. A master plan is set up to re-cultivate public spaces and points of architectural focus. The city reacts interactively to the commands. A dialog is created between user and public space. The tour route is an open structure which can be expanded at any time. Via interfaces the user activates a reaction in the real city by making changes to the virtual model. This results in a dynamic space, a communication based on the results of this transformation. The user interface allows an information transfer between real people and virtual space. Virtual reality then reacts to the input by transferring that information back to reality. The direct influence on the architecture is effected by a media-transformer. It projects an additional perception level on to reality while monitoring the data via various analysis interfaces.

title	Fabrication with Residual Wood through Scanning Optimization and Robotic Milling

summary	The project deals with the use of residual wood of tree stumps and roots through scanning, optimization and robotic milling. Wood logging residue makes up to 50 percent of the trees harvested biomass. (Hakkila and Parikka 2002). Among prevailing strategies is leaving residue on site, and recovering residue for bioenergy. (Perlack and others 2005). The project explores the third strategy, using parts of the logging residue for fabrication, which may reduce the overall amount of wood logging volume. Furthermore approach aims for applying residue in its natural form and taking advantage of specific local characteristics of wood (Desch and Dinwoodie 1996). The project applies the strategy on working with stump and roots of an oak tree. Due to considerations of scale, available milling technics and available resources, chosen goal of the approach is to create a functioning chair prototype. Among the problems of the approach is the complex shape of the residue, uneven quality of wood, varying humidity and contamination with soil. After cleaning and drying, the stump is scanned and a 3D model is created. The 3D model od a stump is confronted with a 3D modelled limits of the goal typology (height, width, length, sitting surface area and overal volume of a chair) and topological optimization algorithm is used to iteratively reach the desired geometry. Unlike in established topological optimization proces, which aims for a minimal volume, the project attempts to achieve required qualities with removing minimal amount of wood. Due to geometric complexity of both stump and goal object, milling with an 6axis industrial robotic arm and a rotary table was chosen as a fabrication method. The object was clamped to the board (then connected to a rotary table) in order to provide precise location and orientation in 3D space. The milling of the object was divided in two parts, with the seating area milled in higher detail. Overall process of working with a residual wood that has potential to be both effective and present aesthetic quality based on individual characteristics of wood. Further development can integrate a generative tool which would streamline the design and fabrication proces further.

title	Educational Parcours for Architectural Photography

summary	Our didactical concept is based on the idea of simulating photographical techniques by using a set of mock-up situations, created with a common CAAD- and visualisation-software (Artlantis).The didactic program (and the mock-up-“parcours“) starts with a two-dimensional object, found on different places in the city or on the campus: an „advertising panel“. With any kind of camera it is possible to take a picture of sufficient quality. When taking the real photo, students have to deal with different points of view, different inclinations of the camera and different zoom-adjustments. When they present their results in digital form, they also have to deal with disappointments in form of distortions of their lenses. The CAD-model of the same situation (professional photographers use the terminus, mock-up“) shows parallels in using different points of view, different zoom-adjustments. Our experience in using this kind of mock-up-simulation is very positive: students develop a new sight to things and procedures which intensifies their consciousness and their knowledge of photographical and architectural situations.

title	The Holy light: a comparison of natural and artificial light in a sacred setting
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 695-699
summary	The design of sacred settings can attempt to enrich the inner spiritual experience of the Lord being the Light. It provides natural light to connect to the divine and artificial light to highlight the rituals associated with this connection. The paper attempts to compare these light effects in a sacred setting; and to utilize popular commercial graphic software in the analyses of these effects. Specifically, AutoCAD and Forum Z are utilized to investigate these differences in viewing the dome's fresco in the historic Church of St. Themonianos in Lysi, Cyprus and in the Byzantic Fresco Chapel in Houston, Texas. The study includes three parts: recreation of a digitized model of the historic church in Cyprus; analyses of light effects in both churches; and a comparison of light effects along accepted lighting guidelines. The conclusion of this examination is that both sources of light complement each other in their effects in sacred settings.

title	Dynamic Designs of 3D Virtual Worlds Using Generative Design Agents
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 239-248
summary	3D virtual worlds are networked environments designed using the metaphor of architecture. Recent developments in 3D virtual worlds focus on interactivity, flexibility and adaptability. Rather than creating virtual environments in which the objects have intelligent behaviours, our research takes a different approach to develop an agent model that is associated with an individual person in the 3D virtual world as a personal design agent. This paper presents a Generative Design Agent (GDA), a kind of rational agent capable of representing a person in a virtual world and designing, implementing and demolishing 3D virtual places based on the occupants' current needs in the virtual world. The core of a GDA's design component is a generative design grammar that is able to capture a style of 3D virtual worlds. 3D virtual worlds designed using the GDA model is another kind of architecture for the "moment".
