title	Investigating cultural uniqueness in theme parks through finding relationships between visual integration of visitor traffics and capacity of service facilities
source	International Journal of Architectural Computing vol. 14 - no. 3, 247-254
summary	The goal of the article is to find the relationships between theme park visitor traffics and service facility location along with their capacities. To do that, we analyzed four Disneylands situated in Paris, Tokyo, and the United States (Florida and California). By analyzing the visual integration of visitor traffics at each Disneyland and calculating the capacities of service facilities such as the attractions, shops, and restaurants, we ran through a linear and a geographically weighted regression analysis. Our results indicate that there is a unique relationship between the service facility placements and the amount of predicted traffic flows for each Disneyland.

title	Piecewise smooth surface reconstruction
source	A. S. Glassner, (ed), Computer Graphics (Siggraph'94 proc.), Annual Conference Series, pp 295-302, July 1994
summary	We present a general method for automatic reconstruction of accurate, concise, piecewise smooth surface models from scattered range data. The method can be used in a variety of applications such as reverse engineering - the automatic generation of CAD models from physical objects. Novel aspects of the method are its ability to model surfaces of arbitrary topological type and to recover sharp features such as creases and corners. The method has proven to be effective, as demonstrated by a number of examples using both simulated and real data. A key ingredient in the method, and a principal contribution of this paper, is the introduction of a new class of piecewise smooth surface representations based on subdivision. These surfaces have a number of properties that make them ideal for use in surface reconstruction: they are simple to implement, they can model sharp features concisely, and they can be fit to scattered range data using an unconstrained optimization procedure.

title	Utilización de un Sig Para la Formulacion de un Diagnostico Socioterritorial de la Ciudad de Buenos Aires (Use of a GIS for the Formulation of a Socio-territorial Diagnostic of the City of Buenos Aires)
source	II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 324-331
summary	The use of a GIS to assist the elaboration of a socioterritorial diagnosis of the City of Buenos Aires. This paper is based on the result of two research projects sponsored by the University of Buenos Aires (Project AR01 0 and Project Cl-94). From the beginning of 1998 onwards these results have been applied to the development of a "socio-territorial diagnosis" of the City of Buenos Aires, an applied research project funded by the Government of the City of Buenos Aires and carried out by the Facultad de Arquitectura, Diseho y Urbanismo, Universidad de Buenos Aires (Research Unit: PROHAB). The main goal of the analysis was the identification of the spatial distribution pattern of of the selected variables, directed to the delimitation of "social areas". The facilities provided by the GIS allowed us to perform this task in an exploratory manner. An analysis of the 3405 census tracts of the City of Buenos Aires (the central part of the agglomeration) is presented here. A great number of indices were constructed based on variables of the Argentine National Census of Population and Housing referred to housing conditions, housing type, provision of services, origin of the population, educational level, etc. This paper describes the various steps necessary for the application of a GIS, including the digitizing of the cartographic base and the statistical elaboration of the census information (provided by the INDEC in magnetic medium). A colour cartographic output that can be considered a first approximation of the "social map" of the city in 1991 is presented.

title	Improving Design Workflow in Architectural Design Applications
source	International Journal of Architectural Computing vol. 4 - no. 4, pp. 1-19
summary	In architectural design software, there is a trend to integrate the whole design process in a single application. Design, 3D modeling, drafting, but also design evaluation and presentation are bundled inside the application. This is especially apparent in applications that adhere to the concept of Building Information Modeling. When we look at the functionality in these applications, however, a disruption of the design process can be encountered, preventing the designer to step back and forth throughout the different design phases or scale levels. Three current architectural design applications are briefly positioned and compared and potential improvements to the workflow are introduced.

title	Representational Limitations and Improvements in Building Information Modeling
doi	https://doi.org/10.52842/conf.ecaade.2008.035
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 35-42
summary	This paper discusses advantages and limitations of different representation types, illustrated with examples from current commercial Building Information Modeling applications. There is still a potential benefit in more thoroughly adapting additional representations to access and manage project data.The paper presents arguments to adapt a hybrid approach, where multiple representations should form a series of interfaces to interact with a building model. Inspiration is derived from software applications not associated with Building Information Modeling.

title	Integration of Virtual Reality within the Built Environment Curriculum
source	ITCon Vol.11 pp. 311-324
summary	Virtual Reality (VR) technology is still perceived by many as being inaccessible and cost prohibitive with VR applications considered expensive to develop as well as challenging to operate. This paper reflects on current developments in VR technologies and describes an approach adopted for its phased integration into the academic curriculum of built environment students. The process and end results of implementing the integration are discussed and the paper illustrates the challenges of introducing VR, including the acceptance of the technology by academic staff and students, interest from industry, and issues pertaining to model development. It sets out to show that fairly sophisticated VR models can now be created by non-VR specialists using commercially available software and advocates that the implementation of VR will increase alongside industry’s adoption of these tools and the emergence of a new generation of students with VR skills. The study shows that current VR technologies, if integrated appropriately within built environment academic programmes, demonstrate clear promise to provide a foundation for more widespread collaborative working environments.

title	Data Informed Branch Typologies for Structurally Optimised Curvilinear Surfaces - 3D Printed Mesh Density System (MDS) as Formwork for Concrete Shell Structures.
doi	https://doi.org/10.52842/conf.caadria.2019.2.401
source	M. Haeusler, M. A. Schnabel, T. Fukuda (eds.), Intelligent & Informed - Proceedings of the 24th CAADRIA Conference - Volume 2, Victoria University of Wellington, Wellington, New Zealand, 15-18 April 2019, pp. 401-410
summary	This research sheds light on the advancement of additive fabrication and its relevance to the construction of curvilinear surfaces. The Mesh Density System (MDS) explored in this paper, is a novel 3D printed dual formwork and reinforcement system for free-form complex concrete geometries. It offers an alternate method to current formwork systems, essentially for thin shell structures. By using multi-cellular distribution and optimised branch structural arrangements, the system optimises form and concrete flow.

title	Digital Design to Digital Production: Flank Milling with a 7-Axis CNC-Milling Robot and Parametric Design
doi	https://doi.org/10.52842/conf.ecaade.2009.323
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 323-330
summary	Just recently Flank Milling has opened up new possibilities in detailing large-scale architectural building envelopes. Whereas examples such as the Hungerburgbahn by Zaha Hadid show the application of Flank Milling at the end of the architectural manufacturing process, our research, in contrast, focuses on the implementation of constraints immanent to manufacturing techniques as early architectural design parameters. This process is explored by the help of generative modeling tools, to allow an intuitive design of freeform parametric curves and surfaces while at the same time obeying crucial geometric conditions. In this paper, we will focus on the “digital design to digital production” process on a 7-axis industrial CNC -robot.

summary	This paper proposes a "Human Aided Hand-Eye System (HAHES)" to aid the autonomous robot for "Digital Twin Model (DTM)" sampling and correction. HAHES combining the eye-to hand and eye-in hand relationship to build an online DTM datasets. Users can download data and inspect DTM by "Human Wearable XR Device (HWD)", then continuous updating DTM by back testing the probing depth, and the overlap between physics and virtual. This paper focus on flexible linear material as experiment subject, then compares several data augmentation approaches: from 2D OpenCV homogeneous transformation, autonomous robot arm nodes depth probes, to overlap judgement by HWD. Then we train an additive regression model with back-testing DTM datasets and use the gradient boosting algorithm to inference an approximate 3D coordinate datasets with 2D OpenCV datasets to shorten the elapsed time. After all, this paper proposes a flexible mechanism to train a vision-based autonomous robot by combing different hand-eye relationship, HWD posture, and DTM in a recursive workflow for further researchers.

title	A First Step Towards an Intelligent Integrated Design System in the Building Field
source	computer Integrated Future, CIB W78 Seminar. September, 1991. Unnumbered pages : ill. includes bibliography
summary	This article presents the work the Knowledge Base Group is achieving towards the integration of Artificial Intelligence based facilities in the Building design process. After an overview of the current state of the integrated design process, the context and the technical guidelines to realize computer integrated software in the building design field is described. Then some tools are presented to model the knowledge (the HBDS method) and to implement such model in our Mips home-made knowledge modeling software platform (including object-oriented database management facilities, expert system reasoning facilities, hypertext edition facilities, 3D-design and 3D-view modules...). Finally the authors describe the Quakes application devoted to assess detached house anti-seismic capabilities during the design process. A deep conceptual model considers all the semantic entities (columns, resistant panels, openings, ...) involved in the anti-seismic expertise. Using both this conceptual model description of a detached house and the 3D design tool, they input the project. Then the seismic expertise is driven in a divide and conquer approach and records the alleged configuration recognized automatically linked to the corresponding section of the building regulation

title	Architectural critique through digital scenariobuilding. Augmenting Architectural Criticism and Narrative
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 697-709
summary	As an idea scenario-building has parallels the use of creative faking in related disciplines, most particularly, in contemporary art. The techniques involved in scenario-building and faking offer us enhanced ways of undertaking creative thinking and critical review of architecture and architectural projects. Critical review and theoretical analysis of architecture can be undertaken via a range of methods that Attoe (1978) classifies as Normative, Interpretive and Descriptive. Digital representation now offers us new ways of augmenting these critical styles in ways that have yet to be fully exploited, and possible means of exploitation are illustrated in this paper. In short the work described here shows how digital techniques can be used to enrich architectural investigation, critical reporting and debate.

summary	This paper introduces a method to obtain quantified style description vector which is for computer analysis input by using image style classification task. In the experiment, 3331 architectural photos of three styles obtained by crawling and filtering were used as training data. A deep convolutional neural network was trained to map architectural images to high-dimensional feature space, and then the high-dimensional style description vector was used to output the measurement results of style cognition with fully connected neural network. Tested by test data-set of 371 architectural pictures, the accuracy rate of style cognition reached more than 80%. The neural network using architectural data training was applied to the style cognition of non-architectural objects, high accuracy rate was also achieved, it proved that this quantified style description vector did include the information about style cognition to some extent instead of simply classification. Finally, the similarities and differences between the cognitive characteristics of style of neural network and human beings are investigated.

summary	In the early design phases, Life Cycle Assessment can assist project stakeholders in making informed decisions on choosing structural systems and materials with an awareness of environmental sustainability through their embodied carbon content; yet embodied carbon is difficult to quantify without detailed design information in the early design stages. In response, this paper proposes a novel data-driven tool, prior to the definition of floor plan layouts to perform embodied carbon evaluation of existing building designs based on a Bayesian Neural Network (BNN) regression. The BNN is built from data drawn from existing floor plans of residential buildings, and predicts material volume and embodied carbon from generic design parameters typical in the early design stage. Users will be able to interact with the tool in Grasshopper or as an online resource, input generic design parameters, and obtain comparative visualizations based on the choice of a construction system and its environmental sustainability in a 'shoebox' interface - a simplified three-dimensional representation of a building's primary spatial units generated with the tool.

source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 786-793
summary	As digital spatial models take on the complex relationships inherent in a lattice of dependencies and variables, how easy is it to fully comprehend and communicate the underlying structure and logical subtext of the architectural model: the metadesign? The design of a building, the relationships between a host of different attributes and performances was ever a complex system. Now the models, the representations, are in the early stages of taking on more of that complexity and reflexivity. How do we share and communicate these modelling environments or work on them together? This paper explores the issue through examples from one particular associative geometry model constructed as research to underpin the collaborative design development of the narthex of the Passion Façade on the west transept of Gaudi’s Sagrada Família church, part of the building which is now in the early stages of construction.

source	Proceedings: SCI 2001, The Fifth Multi-Conference on Systemics, Cybernetics and Informatics, Orlando, Florida, USA, July 22 - 25, 2001. http://www.iiis.org/sci/
summary	This paper presents the first prototype of a reconfigurable Virtual Environment (VE). The objective of the system is to link 3D Intelligent Virtual Environments to interactive planning systems. This type of system makes possible interactive solutions where the user refines a possible configuration and enables the system to generate a complete new solution enforcing all the design constraints, previously programmed. In this first prototype we link our constraint solver with the visualization engine so that the solution produced by the constraint solver is displayed in a VE.

summary	Digitization of three-dimensional sculptures is a well-developed technology for preserving antiquities. After digitizing they could be represented in various computerized spaces, virtually, such as in cyberspace, in virtual reality space, and in augmented reality…etc. However, contrary to physical demonstration of 3D sculptures in traditional museums or exhibitions, the virtual representation may lose some degrees of reality of sculptures or create various ways of interactions for viewing sculptures. In this research, there are three kinds of environments for re-presenting 3D sculptures: the physical reality (PA) in a space, virtual reality (VR) with a big screen, and augmented reality (AR) of Head-Mounted Display (HMD). By utilizing questionnaire to analyze users’ perceptions and requirements of viewing 3D sculptures, this research will compare several aspects, such as visualization, operational interactions, and psychological feelings in the experiment of three exhibition environments. Finally, based on the results from questionnaire, we attempt to propose a suitable environment for exhibiting the virtual 3D sculptures.

summary	The Virtual Reality Modeling Language (VRML) and the World Wide Web (WWW) offer new opportunities to communicate an architect's design intent throughout the design process. We have investigated the use of VRML in the production and communication of construction documents, the final phase of architectural building design. A prototype, experimental Web site was set up and used to disseminate design data as VRML models and HTML text to the design client, contractor, and fabricators. In this paper, we discuss the way our construction documents were developed in VRML, the issues we faced implementing it, and critical feedback from the users of the Web space/site. Finally, we suggest ways to enhance the VRML specification which would enable its widespread use as a communication tool in the design and construction industries.
