title	Using the Mobile Augmented Reality Techniques for Construction Management
doi	https://doi.org/10.52842/conf.caadria.2005.396
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 396-403
summary	In this paper we attempt to develop a new system called “C-Navi” for construction site simulation and management system. By integrating AR technology with mobile computing, the new system will extend the abilities of AR systems to be implemented in large outdoor space. The concept of 4D CAD system is utilized by integrating related information and displaying them in the time-based visualization approach. Our system could help with decision making and also act as a tool for improved communications between project partners.

title	Developing a Spatial Context-Aware Building Model and System to Construct a Virtual Place
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Progress in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN-10: 90-386-1756-9, ISBN-13: 978-90-386-1756-5, p. 343-358
summary	The current notion of space seems to be inappropriate to deal with contemporary and future CAAD applications because it lacks of user and social values. Instead of using a general term called 'space', our approach is to consider the common unit in architectural design process as a place composed of space, user and activity information. Our research focuses on developing a novel intelligent building data model carrying the essence of place. Through our research, the needs of using virtual architectural models among various architectural applications are investigated at first step. Second, key characteristics of spatial information are summarized and systematically classified. The third step is to construct a semantically-rich building data model based on structured floor plan and the semantic location modeling. Then intermediate functions are created providing an interface between the model and future applications. Finally, a prototype system, PlaceMaker, is developed to demonstrate how to apply our building data model to construct virtual architectural models embodying the essences of place.

title	Computational Fluid Dynamics for Urban Design: The Prospects for Greater Integration
source	International Journal of Architectural Computing vol. 9 - no. 1, 33-54
summary	Computational Fluid Dynamics (CFD) has always been used in the field of architecture, urban design and urban planning to understand the patterns of wind flow through the built environment. Its analysis is important to evaluate whether the natural ventilation through a site is adequate to mitigate heat and pollutant to achieve better human comfort in dense urban environments. However, given the complex operational requirements, the response to wind flow is not always done early enough to support planning and design. This paper seeks to illustrate how CFD analysis can aid planning and design of urban areas and investigates the workflow requirements, in the hope of making the CFD simulations more accessible to the practices and contribute to design decisions. It also looks at the present technological advancements and future prospects to assess the scenarios where emerging technologies can make CFD simulation more readily available with affordable and even mobile hardware installations.

title	Representation, re-representation and emergence in collaborative computer-aided design
source	Maher, M.L., Gero, J.S. and Sudweeks, F. (eds), Preprints Formal Aspects of Collaborative Computer-Aided Design, Key Centre of Design Computing, University of Sydney, Sydney, pp. 303-320
summary	Representation of drawings in CAD systems can cause problems during design collaboration. The notion of re-representation is proposed as one way of addressing these problems. Furthermore, re-representation is one way of allowing emergence to occur; emergence is an important aspect of collaborative computer-mediated design. Based on the concept of re-representation a model for collaborative CAD supporting emergence is presented and an example is demonstrated.

title	Remembrane: A Shape Changing Adaptive Structure
source	Gülen Çagdas, Mine Özkar, Leman F. Gül and Ethem Gürer (Eds.) Future Trajectories of Computation in Design [17th International Conference, CAAD Futures 2017, Proceedings / ISBN 978-975-561-482-3] Istanbul, Turkey, July 12-14, 2017, pp. 180-198.
summary	This paper presents a research on adaptive kinetic structures using shape memory alloys as actuators. The target of the research is designing and building an efficient kinetic structural system that could be potentially applied at an architectural scale. The project is based on the study of tensegrity and pantograph structures as a starting point to develop multiple digital and physical models of different structural systems that can be controllably moved. The result of this design process is a performative prototype that is controllable through a web-based interface. The main contribution of this project is not any of the presented parts by themselves but the integration of all of them in the creation of a new adaptive system that allows us to envision a novel way of designing, building and experiencing architecture in a dynamic and efficient way.

title	SURF_TM: A SURFACE SYNTHESIZER FOR ARCHITECTURAL FORMS
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 359-369.
summary	Parametric equation is one of the possible ways to generate free-form architecture in modern age. When working with mathematical software, designers need a way to bring surface mesh to CAD for further design. Surf_TM is an supplemental tool for AutoCAD to import and manipulate surface mesh data from Mathcad. Accompanying with a course taught in Harvard Design School, students gain knowledge in mathematics and use parametric equation as a design tool. This paper elaborates details of the course, the tool, how they work together, and example applications.

title	Transition Rule Elicitation Methods for Urban Cellular Automata Models
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. 53-68
summary	In this chapter, transition rules used in urban CA models are reviewed and classified into two categories: transition potential rules and conflict resolution rules. Then, four widely used rule elicitation methods: Regression analysis, Artificial Neural network (ANN), Visual calibration, and Analytical Hierarchy Processing - Multi Criteria Evaluation (AHP-MCE) are discussed. Most of these methods are data driven methods and can be used to elicit the transition potential rules in the urban CA models. In the following, three possible rule elicitation methods: Interview, Document analysis, and Card sorting are explained and demonstrated. These three methods are driven by knowledge and can be used to elicit conflict resolution rules as well as transition potential rules in urban CA models.

title	Algorithmic Forest - A Study to Generate ‘Light-Revealing’ Structure by Algorithm
source	ETH postgraduate studies final thesis, Zurich
summary	The research to be presented will demonstrate the potential benefitsofalgorithmsbyusing them to design and generate a structure, specificallyalight-revealingstructure. Light is one of the many considerations in architecture, it reveals the building, its place, form, space, and meaning. Light reveals architecture and, in the best instances, architecture also reveals light. Moreover, light and structure are intertwined. Louis I. Kahn said, “Structure is the maker of light. When you decide on the structure, you are deciding on light.“ Particularly, this presentation will focus on a structure, which creates variable lighting effects similar to those created by natural light shining through trees in a forest.

title	Light Pen - Sketching Light in 3D
source	Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 327-338
summary	We describe a lighting design system driven by sketching on 3D virtual models. Conventional lighting design tools simulate the lighting effects of design decisions such as window locations, surface treatments, and fixture placement. Light Pen takes the inverse approach by allowing the designer to indicate desired illumination on a 3D model. This serves as input to a knowledge-based lighting design system, which recommends what lights to use and where to place them, based on the designer's expressed intentions and on the geometry of the space.

summary	Designing a building or a new urban space is collaborative work that involves several people with different backgrounds. To achieve consensus all participants in the process meet to discuss documents such as floor plans and sections. This paper reports on the progress of Space Pen, a new system to allow several users to draw on and annotate a three-dimensional representation of a building remotely over the Internet.

title	Immersive Redlining and Annotation of 3D Design Models on the Web
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 81-98
summary	The Web now enables people in different places to view three-dimensional models of buildings and places in a collaborative design discussion. Already design firms with offices around the world are exploiting this capability. In a typical application, design drawings and models are posted by one party for review by others, and a dialogue is carried out either synchronously using on line streamed video and audio, or asynchronously using email, chat room, and bulletin board software. However, most of these systems do not allow designers to embed annotations and proposed design changes in the threedimensional design model under discussion. We present a working prototype of a system that has these capabilities and describe the configuration of Web technologies we used to construct it.

summary	The Immersive Redliner supports annotation of three-dimensional artifacts in collaborative design. It enables team members to drop annotation markers in a VRML world that are linked to comment text stored on a server. Visitors to the world later can review the design annotations in the locations where they were made. We report on two phases of the Redliner project: the first involves a hypothetical design scenario, the second a real application on a rehabilitation in a residence building in Strasbourg.

title	Responsive Spatial Print Trajectory: 3D Printing of Clay Lattices with Self-Corrective Recalibration
source	ACADIA 2022: Hybrids and Haecceities [Projects Catalog of the 42nd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-7-4]. University of Pennsylvania Stuart Weitzman School of Design. 27-29 October 2022. edited by M. Akbarzadeh, D. Aviv, H. Jamelle, and R. Stuart-Smith. 148-153.
summary	This project presents a novel method of spatially printing clay lattices by controlling fabrication parameters such as the printing head speed and the material extrusion rate following a 3D-choreographed toolpath. Spatial printing refers to the unrestricted movement of the printer nozzle in three axes (x, y, z) when extruding material, as opposed to the conventional 2-axis layer-by-layer deposition that is very slow and results in increased operational costs. This method—enhanced with an integrated industrial laser displacement sensor to collect deflection data subsequently used to calibrate the next layer toolpath geometry in real- time—works optimally with carbon-fiber reinforcements for increased tensile performance.

title	The Vega Platform - IT for the Virtual Enterprise
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 591-616
summary	One of todays many buzzwords is 'virtual enterprise'. The objectives of the ESPRIT project VEGA are the development of an IT platform enabling such enterprises. Virtual enterprise means a number of people or smaller companies grouped together for a distinct contract, which none of them alone could or would able to get and to undertake. Modern decentralized, distributed IT solutions typically could support such virtual enterprises in their competition against those who are big or strong enough to to carry out such contracts with their internal resources alone. VEGA gathers together the necessary components as technically available and extends their capabilities as needed for a platform enabling collaboration in an flexible and distributed environment.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 617-634
summary	The project work described in this paper is a part of the ESPRIT VEGA Project. It is related to two companion papers issued in this conference proceedings. 'Product Data Model for Interoperability in an Distributed Environment' and 'The VEGA Platform' are describing the technological basis for an application modeled to capture and convert the working environment of architects and building engineers, in short: the building design team, to an computer environment. The ESPRIT projects are increasingly forced into 'public and private risk funding and sharing policy. This part of VEGA is explicitly directed to exploitation of the EU funded project. This can be reached by a stepwise (small steps) transition from research to commercial implementation.

source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 277-290
summary	Product Modeling is considered to be an established concept not only for semantically based data exchange, but also for the specification of models, dealing with specific application requirements. The product model approach is regarded to be one step towards a new generation of Computer Aided Architectural Design, and to provide underlying means for enabling communication between different applications on a semantic level. After on overview about the background and the basis principles of product modeling, the authors discuss how product models can be used in commercial developments and in applied research projects.

source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 571-589
summary	This paper belongs to a suite of three interrelated papers. The two others are 'The VEGA Platform' and 'A Dynamic Product Model'. These two companion papers are also based on the VEGA project. The ESPRIT project VEGA (Virtual Enterprises using Groupware tools and distributed Architectures) has the objective to develop IT solutions enabling virtual enterprises, especially in the domain of architectural design and building engineering. VEGA shall give answers to many questions of what is needed for enabling such virtual enterprise from the IT side. The questions range from technologies for networks, communication between distributed applications, control, management of information flow to implementation and model architectures to allow distribution of information in the virtual enterprises. This paper is focused on the product model aspect of VEGA. So far modeling experts have followed a more or less centralized architecture (central or central with 4 satellites'). Is this also the architecture for the envisaged goal? What is the architecture for such a distributed model following the paradigm of modeling the , natural human' way of doing business? What is the architecture enabling most effective the filtering and translation in the communication process. Today there is some experience with 'bulk data' of the document exchange type. What is with incremental information (not data) exchange? Incremental on demand only the really needed information not a whole document. The paper is structured into three parts. First there is description of the modeling history or background. the second a vision of interoperability in an distributed environment from the users coming from architectural design and building engineering view point. Third is a description of work undertaken by the authors in previous project forming the direct basis for the VEGA model. Finally a short description of the VEGA project, especially the VEGA model architecture.

source	7th International Conference on Computer-Aided Architectural Design/ ISBN 0-7923-4726-9 / München / Germany, 4-6 August 1997, 931 p.
summary	Since the establishment of the CAAD futures Foundation in 1985 CAAD experts from all over the world meet every two years to present and at the same time document the state of art of research in Computer Aided Architectural Design. The history of CAAD futures started in the Netherlands at the Technical Universities of Eindhoven and Delft, where the CAAD futures Foundation came into being. Then CAAD futures crossed the oceans for the first time, the third CAAD futures in '89 was held at Harvard University. Next stations in the evolution where in '91 Swiss Federal Institute of Technology, the ETH Zürich. In '93 the conference was organized by Carnegie Mellon University, Pittsburgh and in '95 by National University Singapore. CAAD futures '95 marked the world wide nature by organizing it for the first time in Asia. The seventh CAAD futures is the first being organized by a German University. For the as small as newly and only provisional established CAAD group at the Faculty for Architecture at Technical University München it is honor and challenge at the same time to be the organizer of CAAD futures '97.
