title	A Computational Approach to the Reconstruction of Surface Geometry from Early Temple Superstructures
source	International Journal of Architectural Computing vol. 3 - no. 4, 471-486
summary	Recovering the control or implicit geometry underlying temple architecture requires bringing together fragments of evidence from field measurements, relating these to mathematical and geometric descriptions in canonical texts and proposing "best-fit" constructive models. While scholars in the field have traditionally used manual methods, the innovative application of niche computational techniques can help extend the study of artefact geometry. This paper demonstrates the application of a hybrid computational approach to the problem of recovering the surface geometry of early temple superstructures. The approach combines field measurements of temples, close-range architectural photogrammetry, rule-based generation and parametric modelling. The computing of surface geometry comprises a rule-based global model governing the overall form of the superstructure, several local models for individual motifs using photogrammetry and an intermediate geometry model that combines the two. To explain the technique and the different models, the paper examines an illustrative example of surface geometry reconstruction based on studies undertaken on a tenth century stone superstructure from western India. The example demonstrates that a combination of computational methods yields sophisticated models of the constructive geometry underlying temple form and that these digital artefacts can form the basis for in depth comparative analysis of temples, arising out of similar techniques, spread over geography, culture and time.

title	Digital Reconstructions: Confidence and AmbiguitY

summary	Digital representations have progressed tremendously from the earliest wireframe images to realistic ray-traced renderings that are often indistinguishable from real-life. Yet, in many cases, in the fooling of the eyes, one should not also fool the brain. Especially in the reconstruction of the past, it may be useful for the visualization to also contain information about the certainty of the result. Methods exist to show what data was missing and is now restored and the confidence level of the reconstruction. This in-progress summary paper will discuss the overall usefulness of many of these techniques and list methods from architecture, archaeology, and other fields towards providing information beyond the visualization.

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	Understanding Design Justice in a Bottom-up Housing through Digital Actor-Network Mapping - The case of solidary mobile housing in Brussels
doi	https://doi.org/10.52842/conf.ecaade.2021.1.131
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 131-140
summary	This paper is a study of an ongoing housing project in Brussels (SMH) which involves bottom-up spatial occupation and 'making' by activists, activist architects, social workers and citizens. The particular focus of this paper is on the critical spatial agency of the citizens, activist-architects and artefacts for enabling architectural design justice (ADJ) in the SMH. Building on the Actor-Network Theory of Latour (2005) we developed an analytic method called Actor Link Mapping and Analysis (ALMA) which involves data collection from a wide range of network actors, the generation of a variety of digital network maps, making computational analysis, followed by workshops and interviews to discuss the findings. ALMA was used to recognize potential assets which are essential for design justice practices and networks. The analysis revealed the limits to community control of design processes and practices as well as limits to the conceptual links surrounding socio-spatial equality, thus limits to design justice in the SMH project. Our research also revealed a plethora of new roles and agencies in bottom-up housing production which were essential to understanding the dynamics and power distribution among the different actors.

title	Smart Housing for the Elderly: Understanding Perceptions and Biases of Rural America
doi	https://doi.org/10.52842/conf.acadia.2007.130
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 130-137
summary	It is commonly acknowledged that ‘smart’ environments, interactive architecture and ‘smart’ homes will define the next cutting edge in architectural research. Most critics agree that one of the first problems that ‘smart’ homes will help to address is that of spiraling costs of healthcare and aging-in-place. This may be true for urban settings where there is the financial feasibility for such technologies but what about rural America? It has been conclusively proven that rural America suffers from a lack of healthcare (delivery and access). Prior research (Mathew 2005) has also established that a rural home is different from an urban home. Will technologies designed for the urban home work in a rural setting? And do rural people carry the same attitudes and biases towards technology? This paper continues our research in the design of ‘smart’ rural environments. It summarizes findings from focus group studies conducted in rural communities that help us to understand attitudes of people towards ‘smart’ technology. We will use these findings to examine the feasibility of ubiquitous computing and ‘smart’ spaces in rural areas. In conclusion, we will present guidelines to help designers in the creation of technology to augment healthy aging in rural home settings.

summary	Research on contemporary habitation spaces is directly related to the study of the relationship between new media and everyday life. This paper presents ongoing in-depth research which intends to discuss these relationships in different ways on a conceptual basis. A collaborative multi-users interface is being specially designed, supported by different kinds of electronic equipment. Furthermore, the project’s objective is to analyze how these information and communication technologies are to be used, as well as their impact on poor communities. As a hypothesis, our intention is to verify if the access to information will be able to broaden social interactions and improve new services which have been set up, in order to guarantee a better quality of life. Beyond being a conceptual approach, the study intends to present and examine facts obtained from intervening in a poor district in São Paulo city, Brazil. Using an existing public telecenter as an access provider to the internet, individual TV-connected set-top boxes in 220 apartments in a local social housing complex are being installed, enabling users to communicate through a collaborative multiusers digital interface. Adding a virtual instance to a geographically-based community, the aim of the project is to provide new possibilities to improve dialogue and debates, to encourage more income and cultural activities. It also intends to evaluate the effects of the technological mediation of social relationships, both inside and outside the community, as well as within the physical urban space such as in the dwellings. The results of this study will be useful in defining public policies to be implemented by the Sao Paulo Local Government. The work is being sponsored by FAPESP, which is the Sao Paulo State Funding Agencie, but also by public institutions, private partners and universities. Researchers involved belong to complementary fields such as architecture, urbanism, computer sciences, social sciences, psychology and electronic engineering.

title	Option One-second Iteration - Analysis, evaluation and redesign of a rural housing prototype
doi	https://doi.org/10.52842/conf.ecaade.2019.1.187
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 1, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 187-194
summary	In 2005, the rural housing deficit in Colombia was 1,600,000 units, which is equivalent to 68.25% of the total households. This very high number shows the difficulties faced by public policies on rural housing. This deficit is partly due to logistical problems related to the supply of materials and complexity in construction processes. It is necessary to explore new alternatives to offer more and better homes at lower costs. The research project presented in this manuscript started in 2013 as an initiative to reduce the housing deficit. It proposed to build a rural housing prototype integrating digital manufacturing processes. The performance of part of the structural and enclosing system was evaluated during a first iteration process to include changes in a second iteration later. With the adjustments to the design process discussed here, the prototype is expected to be built and tested to measure its efficiency and functioning.

summary	How can we provide computational supports for product designers to actively utilize existing styles as driving force to achieve new designs? For a new style that can take the advantage from existing styles, we surveyed Case-Based Design and Case-Based Reasoning systems for product design and found discouraging results. We employ Learning Classifier Systems, a machine-learning paradigm, to perform automatic style classification. These classified styles are used to evolve new styles of designs.

summary	4D CAD systems are used by contractors for visually checking the construction process. To enable simulation of the construction process, the construction planner links building components from a CAD model with the activities from a project planning. In this paper we describe a method to generate a project planning directly from a CAD model using basic construction knowledge. A case study is discussed briefly to show the current results and the shortcomings. Finally an outlook is presented on a more advanced implementation that is (also) useful for designers.

title	From CAD to VR – Implementations for Urban Planning and Building Design
doi	https://doi.org/10.52842/conf.ecaade.2005.399
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 399-405
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	Interactive Rind Modeling for Architectural Design
source	International Journal of Architectural Computing vol. 3 - no. 1, 93-106
summary	The paper presents a new modeling technique for architectural design. Rind modeling provides for the easy creation of surfaces resembling peeled and punctured rinds. We show how the method's two main steps of creation of a shell or crust and then opening holes in the crust by punching or peeling can be encapsulated into a real time semi-automatic interactive algorithm.The rind modeling method allows us to develop a user-friendly tool for designers and architects. The new tool extends the abilities of polygonal modeling and allows designers to work on structured and consistent models for architectural design purposes. Rind modeling gives architects and designers a processing flexibility. It can be used in conceptual modeling during the early design phase. It can also be efficiently used for creating variety of shell structures for architectural design.

summary	Interactive and media-rich digital representations are being increasingly used to offer passages through time and space, a role that was traditionally supported by travels and travelogues, maps, sketches, books and oral histories. In the last two decades, a number of projects have been implemented using digital media with the aim of recording past and extant artefacts and environments. However, the future of such digital past remains as fragile as the memories and moments it tries to capture. There is a need to go beyond creating introverted and closed historical reconstruction projects. This paper surveys significant issues and describes our ongoing work in developing an interpretive, extensible and referential framework toward virtual reconstruction projects.

title	VISION OR RETROSPECTION INTO THE PAST: SCIENTIFIC VISUALIZATION IN THE RECOVERY OF PATRIMONIAL URBAN SPACES
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 2, pp. 700-706
summary	This paper shows the use of digital means in the presentation and relation between the perception of those who have walked by in the past and circulate at present through the Baralt Square space, at specific historic periods, with the purpose of reconstructing the different urban scenarios, and foresee their future, through the use of scientific visualization. The digital reconstruction of the square, of colonial origin, is a complex process. This multifunctional space represented forms and types of societies, as the various actors participated with perceptions and perspectives which were apart from reality, imposing their vision and interests, defining themselves in the materialization of the space-site. This research originates the urban analysis and the interpretation of the public space with the help of input devices and real-time visualizers. Interaction, virtual surroundings and mixed reality technologies may contribute in designing tools for the recovery of patrimonial surroundings. [Full paper in Spanish]

title	Creating Physical Models Using Virtual Reconstructions: Mixed CAM-techniques for a Viennese Synagogue Scale-model
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 108-113
summary	In the framework of a preceding SiGraDi-conference the virtual reconstruction work of Viennese Synagogues was elaborated. The focus of this continued research project is laid on historic/reconstructive modeling, which has specific requirements towards the modeling and subsequent production of scale models. In this paper, the prerequisites of 3D-printing and lasercutting technology for model making will be presented. This includes aspects of scale and handling of individual building elements regarding the possibilities and limitations for each specific CAM-technique. Compared to the rendering models, the modeling procedures for scale-model fabrication had to be adjusted. For example, certain dimensions for details and the structural strength of 3D-printed parts have to be taken into account. Due to economical and constructional reasons as well the printing time involved, a scale-model should be created by means of mixed CAM-techniques; building components have to be split up and assigned accordingly.

title	The Calabozo:Virtual Reconstruction of a Place Based on Testimonies
source	International Journal of Architectural Computing vol. 3 - no. 3, 281-298
summary	The objective the research reported here is to create a visualization of a place based on personal experiences. My research addresses this issue through a case study: the visualization of a women's political prison during the Uruguayan military dictatorship (1973–85). The proposed visualization is based on these women's personal experiences of the solitary confinement cell (calabozo). Compared with their male counterpart, women's memories about prison have been traditionally relegated to a second level in Uruguay. The visualization aims to communicate these women's experiences of the calabozo through a video installation. This article first reviews relevant precedents to the case study and to virtual reconstructions and later describes the video installation.

summary	The continuous collection of data on the state of facilities appears increasingly feasible due to advances in sensing technologies. In this context, we explore the application of tag-based location-sensing to reconstruct models of existing buildings. We describe tag-based building representations, which are complete under certain conditions for the automated conversion to boundary-based building representations. The latter have a rich structure and are useful for various construction-related applications. We describe and demonstrate with a system prototype how spatial reasoning methods facilitate the conversion process.

title	Interactive Visualization of Large-Scale Architectural Models over the Grid
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. 93-102
summary	Virtual reconstruction of the ancient Chinese Chang'an city has been continued for ten years at the National University of Singapore. Motivated by sharing this grand city with people who are geographically distant and equipped with normal personal computers, this paper presents a practical Grid-enabled visualization infrastructure that is suitable for interactive visualization of large-scale architectural models. The underlying Grid services, such as information service, visualization planner and execution container etc, are developed according to the OGSA standard. To tackle the critical problem of Grid visualization, i.e. data size and network bandwidth, a multi-stage data compression approach is deployed and the corresponding data pre-processing, rendering and remote display issues are systematically addressed.
