title	Location of a Point in a Planar Subdivision and its Applications
source	SIAM Journal of Computing. September, 1977. vol. 6: pp. 594-606 : ill. includes bibliography
summary	Given a subdivision of the plane induced by a planar graph with n vertices, in this paper the problem of identifying which region of the subdivision contains a given test points is considered. A search algorithm, called point-location algorithm, which operates on a suitably preprocessed data structure is presented. The search runs in time at most O((log n)2), while the preprocessing task runs in time at most O(n log n) and requires O(n) storage. The methods are quite general, since an arbitrary subdivision can be transformed in time at most O(n log n) into one to which the preprocessing procedure is applicable. This solution of the point location problem yields interesting and efficient solutions of other geometric problems, such as spatial convex inclusion and inclusion in an arbitrary polygon

summary	To the architect, city zoning ordinances that pertain to site setbacks and building envelope profiles are often viewed as restrictive and introduced late in the design process. Conversely, to the urban planner, building design that is more individual, varied, and/or formally sculptural can be viewed as having a negative impact on the urban fabric. Is there a way to create a healthy dialogue between these seemingly polarizing disciplines with a common language?

title	Digital Origami: Modeling Planar Folding Structures
doi	https://doi.org/10.52842/conf.acadia.2011.x.o0g
source	Parametricism (SPC) ACADIA Regional 2011 Conference Proceedings
summary	This paper presents a surface manipulation tool that can transform any arrangement of folding planar surfaces without the need to custom program for each instance. Origami offers a finite set of paper-folding techniques that can be cataloged and tested with parametric modeling software. For this work, Rhinoceros and Grasshopper have been chosen as a software platform to generate a parametric folding tool focusing on single surface folding, particularly where surfaces can transform from one configuration to another while retaining their planarity.

title	Context Aware Paper-Based Review Instrument A Tangible User Interface for Architecture Design Review
doi	https://doi.org/10.52842/conf.acadia.2006.317
source	Synthetic Landscapes [Proceedings of the 25th Annual Conference of the Association for Computer-Aided Design in Architecture] pp. 317-327
summary	We describe the design and implementation of a prototype computer-supported collaborative work (CSCW) environment for review of architectural construction documents. This environment utilizes a novel plain-paper tangible interface that supports shared activity such as review of construction documents using an “over the shoulder” computational assistant called CAPRI.Despite the increasing use of computers, work in most architecture firms still largely revolves around paper drawings. Architects structure their work around paper instead of digital representations for reasons of legal liability and tradition, as well as technical limitations. While hardcopy is intuitive, dense, and easy to access, it lacks direct connection to the wide range of design knowledge increasingly available in interactive design environments. This lack is felt most acutely during design review processes, when the designer or reviewer is often called upon to consult and consider holistically a variety of supporting (backing) documents, a task which requires focused attention and a good memory, if errors are to be avoided.Our prototype system enables multiple reviewers to interact equally with a paper construction document using a tangible interface to query detail and backing data from a project knowledge base. We believe this will decrease the reviewer’s cognitive load by bringing design data to them in a contextual and timely way. In doing so, we believe errors will be caught sooner and mistakes reduced.

summary	Computer graphics have developed efficient techniques for visualisation of the real world. Many of the algorithms have a physical basis, such as computational models for the light and the shadow, models of real objects (buildings, mountains, roads and so on) and the simulation of natural phenomenon. Now computer graphics techniques provide the virtual world with a perception of three dimensions. The concept of the virtual world and its technology have been expanding and intensifying in recent years. Almost everything in the real world has been simulated in virtual world. When it comes to a terrain model, what we need is labour and time. But now it is possible to simulate terrain like the real world using fractals in computer graphics with a very small program and small data set. This study aims to show how to build a real world impression in the virtual world. In this paper the authors suggest a landscape design method and show the results of its application.

title	Visualisation of Historic Village of New Lanark
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 177-178
summary	The existing historic city attracts the attention of architects and educators for its architectural value and history. In addition, many researches on visualisation of historic sites such as world heritage sites are in progress in order to represent the importance of preservation and restoration. New Lanark is the best-preserved example of a cotton-spinning village from the early period of Britain’s industrialisation, and is of international significance in terms of economic, architectural and social history. The village has also been nominated for inclusion in UNESCO’s list of World Heritage Sites. This paper aims to describe development procedure of virtual historic village of New Lanark for educating people about its significant social history and a unique type of building. A multimedia environment is useful for this purpose considering dynamic links among different kinds of resources such as text, images, 3D models and animations. Through this environment people can access from where they are to virtual heritage and navigate 3D space by animation with virtual guidance.

title	Alternative Design Comparative System in Collaborative Design
doi	https://doi.org/10.52842/conf.caadria.1998.327
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 327-335
summary	The evaluation of alternative design sets is important phase for quick design decision and new design conception, and it is repeatedly processed. To proceed design process in standard, the repetition is reduced to minimum. And design must be optimized in limited cost and time. For smooth and fast process lots of alternative design sets are provided within the limit of possibility and it must be evaluated appropriately. It's possible to evaluate alternative design sets using various media. This paper describes the characteristics of various media which have been used for evaluation of alternative design sets, and propose alternative design comparative system based on the findings of case studies.

source	Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
summary	The architectural design requires collaboration among various participants, such as architects, clients, engineers in the stages of the design process. The Sasada laboratory has been involved in the various collaborative architectural design projects. The authors found several important issues in the process of those projects. Firstly, the presentation data is composed of different kinds of data such as documents, computer generated still images, movies and 3D objects. The participants involved in those projects need to access these data as necessary. Secondly, it is virtually impossible for all participants to attend at the same time and place. Therefore, computer networked collaborative design work is essential, in particular, for an international project and for a complex architectural design project.

title	Sustainable Design Framework for the Anthropocene - Preliminary research of integrating the urban data with building information
doi	https://doi.org/10.52842/conf.ecaade.2019.2.561
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 2, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 561-568
summary	In terms of the efficiency and informatization in the architecture and construction industry, the Fourth Industrial Revolution presents positive aspects of technological development, but we need to discuss the expanded concept, the Anthropocene. The era of the human-made environment having a powerful influence on the global system is called Anthropocene. Since the 1950s, many indicators representing human activity and earth system have shown the 'Great acceleration'. Currently, lots of urban data including building information, construction waste, and GHG emission ratio is indicating how much the urban area was contaminated with artifacts. So, the integrated planning and design approach are needed for sustainable design with data integration. This paper examines the GIS, LCA and BIM tools focusing on building information and environmental load. With the literature review, the computational system for sustainable design is demonstrated to integrate into one holistic framework for the Anthropocene. There were some limitations that data was simplified during the statistical processing, and the framework has limitations that must be demonstrated by actual data in the future. However, this could be an early approach to integrating geospatial and environmental analysis with the design framework. And it can be applied to another urban area for sustainable urban models for the Anthropocene

title	Design Adaptation for Handling Design Failures
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 567-576
summary	This research deals with two important issues in Case-based Design (CBD): a structure of design cases and a process of design adaptation for handling design failures. The structure of design cases involves problem situation, design specification, design tasks, design solutions, causal explanation, past design failures as well as design performance. It has been noticed that how to represent a structure of design cases and how it can be used in actual a process of design adaptation process are important in Case-based Design. Adaptation process in Case-based Design is also critcial, especially in handling design failures. The description and the analysis of design adaptation process in the context of Case-based Design paradigm is the major focus of this research. A model of casual explanation is presented as an useful tool for identifying sources of design failures. For efficiently handling design failures based on causal explanation, it is essential to characterize various design failures and to devise an adequate structure of adaptation process. Applicability of adaptation process is demonstrated in an exemplary kitchen layout.

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu, 30050, TAIWAN The adaptation of the word cyberspace (Gibson, 1984) following the emergence of the World Wide Web Internet not only succinctly revolutionized the correlation of time and space but also poised to challenge how we view the existing spatial concept. This research tries to use protocol analysis to examine text-based cyberspace, such as bulletin board, chart rooms and so forth, and the objective of this research is to realize the spatiality of cyberspace through the cognitive point of view, and to compare the differences of the definitions and perception ways of spatiality between people with general domain and in design fields. Finally, we validate the existence of cyberspace, where the process not only allows further categorization of spatial elements concluded from the earlier study, but discover that varied backgrounds can affect how a user defines and perceives cyberspace (Strate, 1999).

summary	Graduate Institute of Architecture, National Chiao Tung University, Hsinchu 30050, Taiwan The evolution of design media has kept a close relationship with the development of design methods in the history. Nowadays, different computer media have been used in different stages of the design process. It is to believe that computer media have great impact on the design process and methods. The objective of this paper is to realize the design process and methods when designers use computer modeling to tackle an architectural design problem. The methodologies are non- participant observation and retrospection. The findings of this research prove that media does contribute to the changes in design process and methods. Not only does its conclusion help to better understand properties of different media, but also benefit the development of computer media.

summary	Korean traditional structure is constructed as prefabrication jointed in largely characterized by its unique components under the specific rules of assembly and proportion. This point is a double-edges sword. Because, while various shapes and sizes of components based upon an objected-oriented form appear the potential possibility of producing changeable prototypes to build up, these various characters of components and several jointed methods has made difficulties to handle. Accordingly, an automatic 3D modeling algorithm is focused on the methodology of changeable prototypes of Korean Traditional architecture keeping traditional jointed methods with setting various characters of components

summary	Having as topic for the conference the tile with keywords such as culture, technology, and architecture, we were expecting to find out the relationships among those three domains, and how they are interrelated in this fast growing information society. This triangular relationship has been established based on the increasingly noticeable paradigm shift from traditional computer-aided design research in architecture to research in diverse areas such as virtual environments and communities and interactive smart spaces, including the consideration of sociocultural aspects along with the technological issues. Making virtual environments focuses on creating a new, yet virtual world where people can inhabit or visit for diverse purposes. The virtual architecture becomes a medium for diverse communications as well as digital contents for the new media industry. For example, virtual heritage projects introduce a new way of preserving historic buildings and sites. At the same time, interactive smart spaces often combine two different worlds: real and virtual worlds. Growing digital technologies enables us to create intelligent physical spaces where computers are ubiquitous and invisible in space, and thus human beings can interact with architectural spaces, not necessarily with computers directly. At this point, issues on virtual reality (VR) and human computer interactions (HCI) become architects' and designers' concerns in socio-cultural aspects. The proceedings of the Nineth International Conference on Computer-Aided Architectural Design Research in Asia, presents 74 papers which were selected from the 131 submissions through a blind review of 58 international reviewers. Each submission was reviewed by three reviewers and the final acceptance was based on their recommendations.

summary	This paper describes the color design process of the house in the village. The color design process proposed in this paper constitutes design stages such as color selection, color application, and color design analysis and evaluation. In the color selection step, a method of arranging colors using a color pallet or a color scheme is described. The color application stage includes the process of creating a village color design alternatives by specifying the color information of the hue, value, and saturation based on the BIM model. The color analysis stage is to numerically identify the color design attributes of the generated color design alternatives. The reason for color analysis and evaluation is to produce various design alternatives with the color harmony and improve the quality of the design.
