title	Fuzzy Modeling of Floor Plan Layout

summary	Fuzzy modeling provides methods and techniques for qualifying and quantifying imprecise and uncertain information. The main advantages of fuzzy design representation are fluency, abstraction and continuity, at a level similar to that of analogue techniques, as well as the possibility of local autonomy, i.e. segmentation of a representation into self-regulating and cooperating components. The paper investigates the applicability of fuzziness to digital architectural sketching of floor plan layouts. Based on an analysis of the paradigmatic dimension in analogue floor plan sketches three alternative forms are proposed: (1) Canonical objects with tolerances, (2) objects described by minimal and maximal values, and (3) point sets which decompose the form of an object into a number of discrete, autonomous particles that describe the object by their position and spatial or structural relationships.

title	Semi-automatic extraction of buildings based on hybrid adjustment using 3D surface models and management of building data in a TIS
source	Vienna University of Technology
summary	A new method for semi-automatic building extraction together with a concept for storing building models alongside with terrain data in a topographical information system (TIS) is presented. A user interface based on Constructive Solid Geometry is combined with an internal data structure completely based on boundary representation. Each building can be de-composed into a set of simple primitives which are reconstructed individually. After selecting a primitive from a data base of common building shapes, the primitive parameters can be modified by interactive measurement in digital images in order to provide approximate values for automatic fine measurement. In all phases, the properties of the boundary models are directly connected to parameter estimation: the parameters of the building primitives are determined in a hybrid adjustment of camera co-ordinates and fictitious observations of points being situated on building faces. Automatic fine measurement is an application of a general framework for object surface reconstruction using hierarchical feature based object space matching. The integration of object space into the matching process is achieved by the new modeling technique. The management of both building and terrain data in a TIS is based on a unique principle. Meta data are managed in a relational data base, whereas the actual data are treated as binary large objects. The new method is evaluated in a test project (image scale: 1:4500, 70 % overlap, 50 % side lap). The automatic tool gives results with an accuracy of +-2-5 cm in planimetric position and +-5-10 cm in height.

source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	In this paper we construct an information-theoretic model ofarchitectural drawings. This model is then used to quantify and measurethe complexities and similarities of drawings. The approach is appliedwithin a linear qualitative shape representation but can be generalized toother types of representation. The descriptive and analytic power of theproposed methods are demonstrated by studying the time evolution ofthe architectural plans produced by Aalto and Kahn and by comparingthem to each other.

title	Emergence in a Recognition Based Drawing Interface
source	J. S. Gero, B. Tversky and T. Purcell (eds), 2001, Visual and Spatial Reasoning in Design, II - Key Centre of Design Computing and Cognition, University of Sydney, Australia
summary	People perceive patterns in representations, patterns that may nothave been initially intended. This phenomenon of emergence is deemed toplay an important role in design. Computer based design assistants canand should support this human perceptual ability, using patternrecognition to anticipate human designers’ perception of emergent shapesand supporting the subsequent manipulation of and reasoning with theseshapes as part of the design. Freehand drawing programs with gesturerecognition are well positioned to implement shape emergence. Supportfor emergent shapes in the Back of an Envelope system is described.

title	An Interactive Shape Modeling System for Robust Design of Functional 3D Shapes
doi	https://doi.org/10.52842/conf.acadia.2001.248
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 248-257
summary	In Architecture, it is essential to design functional and topologically complicated 3D shapes (i.e. shapes with many holes, columns and handles). In this paper, we present a robust and interactive system for the design of functional and topologically complicated 3D shapes. Users of our system can easily change topology (i.e. they can create and delete holes and handles, connect and disconnect surfaces). Our system also provide smoothing operations (subdivision schemes) to create smooth surfaces. Moreover, the system provides automatic texture mapping during topology and smoothing operations. We also present new design approaches with the new modeling system. The new design approaches include blending surfaces, construction of crusts and opening holes on these crusts.

title	Modeling irregular and complex forms
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Computational technologies provide arguably the first real opportunity architectural design has had for a comprehensive description of built form. With the advent of affordable computer-aided design systems (including drafting, modeling, visualization and simulation tools), architects believe they can be in full control of geometric aspects and, through these, of a wide spectrum of other aspects that are implicit or explicit in the geometric representation. This belief is based primarily on the efficiency and effectiveness of computer systems, ranging from the richness and adaptability of geometric primitives to the utility of geometric representations in simulations of climatic aspects. Such capabilities support attempts to design and construct more irregular or otherwise complex forms. These fall under two main categories: (1) parsing of irregularity into elementary components, and (2) correlation of the form of a building with complex geometric structures.The first category takes advantage of the compactness and flexibility of computational representations in order to analyse the form of a design into basic elements, usually elementary geometric primitives. These are either arranged into simple, unconstrained configurations or related to each other by relationships that define e.g. parametric relative positioning or Boolean combinations. In both cases the result is a reduction of local complexity and an increase of implicit or explicit relationships, including the possibility of hierarchical structures.The second category attempts to correlate built form with constraints that derive usually from construction but can also be morphological. The correlation determines the applicability of complex geometric structures (minimally ruled surfaces) to the description of a design. The product of this application is generally variable in quality, depending upon the designer's grounding in geometry and his ability to integrate constraints from different aspects in the definition of the design's geometry.Both categories represent a potential leap forward but are also equally hampered by the rigidity of the implementation mechanisms upon which they rely heavily. The paper proposes an approach to making these mechanisms subordinate to the cognitive and technical aspects of architectural thinking through fuzzy modeling. This way of modeling involves a combination of (a) canonical forms, (b) tolerances around canonical forms and positions, (c) minimal and maximal values, (d) fuzzy boundaries, and (e) plastic interaction between elements based on the dual principles of local intelligence and autonomy. Fuzzy models come therefore closer to the intuitive manners of sketching, while facilitating transition to precise and complex forms. The paper presents two applications of fuzzy modeling. The first concerns the generation of schematic building layouts, including adaptive control of programmatic requirements. The second is a system for designing stairs that can adapt themselves to changes in their immediate environment through a fuzzy definition of geometric and topological parametrization.

title	LOS "SPIROSPACES"
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 179-187.
summary	This paper deals with “Spirospaces”. These are a conversion to the third dimension of the two dimensional geometric entities called “Spirolaterals”. Abelson, Harold, diSessa and Andera (1968) gave the first rules concerning Spirolaterals. To obtain a Spirolateral from a set of straight lines, the first of them must be one unit long and the following must be incremented one unit at each step, at the same time that they turn in a constant direction. Odds (1973) establish the variation of the rotation direction, either to the left or the right. However, he did not give a mathematical relation able to calculate open Spirolaterals. Krawczyk (2001) developed a computer program that generates Spirolaterals following the method suggested by Abelson. These are Spirolaterals obtained by enumeration without a predictive mathematical formula. Krawczyc went farther proposing Spirolaterals based in curved lines. He pointed out that there are a variety of spirolateral forms that have architectural potentiality. Following this, the architectural potentiality of Spirolaterals is the basis of this paper. To take advantage of that potentiality a computer program was implemented to generate spatial configurations based in Spirolaterals. When a third dimension is given to the Spirolaterals they become Spirospaces. These new entities need spatial and design parameters to be useful for architectural purposes. Barrionuevo and Borsetti (2001) gave results about that work establishing the concept of Spirospaces. The aim of this paper is to describe a work directed to improve rules and procedures concerning Spirospaces. It is expected that these procedures governed by the proposed rules can be employed as tools during the early steps in the architectural design process. In this work some aspects concerning Spirospaces are considered. First, Spirolaterals are presented as the predecessors of Spirospaces. Second, Spirospaces are defined, together with their structural parameters. Architectural modeling is studied at the light of two special elements of the Spirospaces: Interstitial spaces and Object spaces. Next, a computer program is presented as the appropriate tool to model configurations having architectural potentiality. Finally, the results obtained running the computer program are analyzed to determine their possible use as architectural forms. Several graphic illustrations are presented showing steps going from the exploration of spatial alternatives to the selection of a specific configuration to be developed. It is expected that the described computer program could be employed as a design aid tool. As the operation of the program generates a variety of spaces able to dwell architectural objects, it eases the search of configurations suitable to specific functions. The results obtained have the possibility of being exported to computer graphic applications able to add materials, lights and cameras.

title	Construyendo una ciudad sostenible en la frontera: planificación de la ciudad de Colombia, Nuevo León, México [Constructing A Sustainable City In the Border: Planning of the City of Colombia, Nuevo León, Mexico ]
source	2da Conferencia Venezolana sobre Aplicación de Computadores en Arquitectura, Maracaibo (Venezuela) december 2001, pp. 194-203
summary	The policy rationale for promotion of urban development in the Mexico-Texas borderland of Nuevo León is likely to be sustained and even strengthened. The University of Texasí participation in new town planning for Colombia spans at least three hierarchical levels with students, faculty members, practitioners and government officials joining efforts. At the ìstudio levelî, students completed a comprehensive landscape assessment for portions of the future city using GPS surveying and GIS database and modeling. Graduate students, using field data, updated 2000 maps/shapefiles, and spatial modeling as an analysis tool, created a series of spatial models to produce useful information about the study areaís inherent suitability for agriculture, human settlement and preservation. This work culminated in a research symposium, planning charrette, refinement of land use and infrastructure assumptions, and the development of masterplan elements for the future city. In contrast to the professional firm, the project provides unique opportunities for intensive learning and applied research that contribute to the ecological, social and economic well-being of new cities and developing regions,

title	The Wooden Construction data modeling of korean traditional architecture - Focused on the structure of Gongpo in Buseoksa MuRyangsujun
doi	https://doi.org/10.52842/conf.caadria.2001.265
source	CAADRIA 2001 [Proceedings of the Sixth Conference on Computer Aided Architectural Design Research in Asia / ISBN 1-86487-096-6] Sydney 19-21 April 2001, pp. 265-274
summary	Finding national identities from its traditional heritages might be an important research issue especially for Asian architects and researchers. Nevertheless, it is noticed that the structure of Korean traditional architecture has not been fully explored in a systematical or computational manner and its information is not shared efficiently. This study thus explores a computational way of structuring construction knowledge and building information of Korean traditional architecture.Ý To do this, we select a well-known old temple building, Buseoksa Muryangsujun, one of the oldest Buddhist temple in Korea, as a prototype. We first build an accurateÝ three-dimensional model of the building with an aid of a traditional building expert, categorize its building components, and then analyze their connectivity and the connectivity patterns and rules by especially focusing on the capital order system, called Gongpo. The result of the study shows several schema diagrams representing the wooden construction data model carefully designed for an intelligent building simulation and generative system that will be developed in the near future.Ý The paper also demonstrates a way of computationally describing some shape grammars that explain the components' connectivity.

summary	The paper describes development of a large-format panoramic display environment. Unlike the ‘window-on-the-world’ metaphor associated with small displays, immersive environments foster a sense of ‘being-in-the-world’. That raises a question: Which aspects of human-computer interaction and information perception scale up or change substantially from small displays to immersive environments? The paper first describes implementation of our display environment, projects being explored in it, and motivates a focused research agenda. Finally, the paper describes an experiment to study differences in spatial judgments by subjects while working in traditional and immersive environments.

title	Information Rich 3D Computer Modeling of Urban Environments
source	Working Paper 35, Centre for Advanced Spatial Analysis Working Papers; London, August 2001
summary	We are living in an increasingly information rich society. Geographical Information Systems now allow us to precisely tag information to specific features, objects and locations. The Internet is enabling much of this information to be accessed by a whole spectrum of users. At CASA we are attempting to push this technology towards a three-dimensional GIS, that works across the Internet and can represent significant chunks of a large city. We believe that the range of possible uses for such technology is diverse, although we feel that urban planning is an area that can benefit greatly. An opportunity to push this ìplanning technologyî arose when CASA won a tender from Hackney Council to develop a dynamic website for community participation in the process of regenerating the Woodberry Down Estate. This is a run down part of northeast London that is undergoing a major redevelopment. CASA has developed a system that not only informs the local residents about the redevelopment process but it also enables them to use dynamic visualisations of the ìbefore and after effectsî of different plans, and then to discuss and vote on the variety of options.

title	Modeling acoustics in virtual environments using the uniform theory of diffraction
source	Siggraph 2001
summary	Realistic modeling of reverberant sound in 3D virtual worlds provides users with important cues for localizing sound sources and understanding spatial properties of the environment. Unfortunately, current geometric acoustic modeling systems do not accurately simulate reverberant sound. Instead, they model only direct transmission and specular reflection, while diffraction is either ignored or modeled through statistical approximation. However, diffraction is important for correct interpretation of acoustic environments, especially when the direct path between sound source and receiver is occluded. The Uniform Theory of Diffraction (UTD) extends geometrical acoustics with diffraction phenomena: illuminated edges become secondary sources of diffracted rays that in turn may propagate through the environment. In this paper, we propose an efficient way for computing the acoustical effect of diffraction paths using the UTD for deriving secondary diffracted rays and associated diffraction coefficients. Our main contributions are: 1) a beam tracing method for enumerating sequences of diffracting edges efficiently and without aliasing in densely occluded polyhedral environments; 2) a practical approximation to the simulated sound field in which diffraction is considered only in shadow regions; and 3) a real-time auralization system demonstrating that diffraction dramatically improves the quality of spatialized sound in virtual environments.

title	Making Digital Architecture: Historical, Formal, and Structural Implications of Computer Controlled Fabrication and Expressive Form
doi	https://doi.org/10.52842/conf.ecaade.2001.239
source	Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 239-244
summary	Digital output from computer modeling represents a significant new method for visualization and fabrication of architecture. The ability to move directly from three-dimensional modeling to real three-dimensional output challenges the need for traditional means of representation such as plan, section, etc. Moreover, the necessity for conversion of architectural intentions into a code (construction documents, shop drawings, etc.) to be translated by the contractor will also be tested with these new potentials in fabrication. This subjugation of traditional forms of representation and fabrication has serious implications for architectural design process and production. The intention of this paper is to scrutinize underlying issues inherent in a design process of developing architectural solutions using the computer both as a tool for threedimensional visualization as well as for guiding three-dimensional fabrication. Precedent of historic expressive architectural form (seen through the lens of fabrication) will be presented to lay the foundation for the examination of new fabrication techniques and structural concerns for computer generated expressive forms. A series of rapid prototype studies from a digital architecture seminar will also be analyzed to outline the need for developing visualization/fabrication process ideas and research into methods for making digital architecture.

summary	The sometimes complex architectural shape of halls creates modelling difficulties as the simulation computing systems need plane surfaces. In order to approach a perfect shape of curved surfaces, a big number of facets is necessary. This poses, as a consequence, computer memory problems which is the case of the horse shoe shaped Opera House with its richly decorated columns, balconies, etc. This paper compares the acoustical measurement results and the calculation results of a computer simulation software applied on several models (from the most simple till the most complex ones) of the Grand Theatre of Bordeaux.

title	Definition of a Method of Limits of the Simplification of a Hall Model in a CAD System to Diminish Falsification of Acoustic Simulation Results
doi	https://doi.org/10.52842/conf.ecaade.2005.695
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 695-704
summary	During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

title	SpaceMaker: A Symbol-based Three-dimensional Computer Modeling Tool for Early Schematic Development of the Architectural Design
source	University of Washington, Design Machine Group
summary	Designing architecture is an action of creating space. Architects start designing by making twodimensional (2-D) drawings in order to explore alternatives of spatial arrangement. However, architects are actually working with three-dimensional (3-D) space. They see 3-D space in their mind’s eye when making sketches in 2-D. It is thus valuable to help designers truly see 3-D space during designing. In addition, different spaces may have different functions and configurations of architectural components. Architects usually use text labels in their drawings to identify architectural concepts. They identify the function of space and remind themselves of the proposed configuration of architectural elements when labeling each space with a symbol. By recognizing the text label, it is possible to identify the architectural configuration of the space. Therefore, it is possible to create a 3-D modeling tool based on the recognition of labels in freehand sketches. This thesis introduces a symbol-based 3-D modeling tool – the SpaceMaker – that allows designers to make freehand floor-plan drawings to explore the initial concept of spatial layout and allows users to apply labels to identify different types of space. Finally, the program converts those floor plans into 3-D models according to the labels. In the SpaceMaker, a designer predefines a label by assigning it four boundary elements that encircle a space. When the designer draws the label in the sketch floor plan, the SpaceMaker then recognizes the label and constructs the space based on the defined boundary condition in a VRML (Virtual Reality Modeling Language) format that enables the designer to view the 3-D space through a VRML enabled web browser.

title	Defects Defined by Form Making Method for Improving Generative Design System
source	International Conference on Generative Art
summary	Evolutionary-based Generative Design System (GDS) is generally designed for industrial designers during the early stage of conceptual design. Although “additive” Rapid Prototyping (RP) methods are commonly applied for the physical realization, grown Surfaces Object (SO) created from these GDS still has room to be considered to a combined workable volume,especially for the more complex design. The inarticulate processes from GDS to Generative Production System (GPS) are linking up with different aspects and contexts as well as the conventional Computer-Aided Design (CAD)/RP integration, which has been conducted for along time. There are design constraints existing between 3D SO in industry design representation and feasible 3D production solution. Perception to object designing with knowledge is limited at SO forming by incomplete interpretations. Meanwhile, it is difficult to discern the problemsof incomplete object generation as hidden illegal design occurred from time to time because of the design constraints, despite the completion of the design representation. It has led to some of the invalidity of surface feature at the end. The reconstruction of the RP process ofthe SO pre-processing procedure can help to clarify these defects with thickness requirement in generative production. The aim of this paper is to verify an effective generative design strategy as a possibility ofimplementing method(s) or tool. They will be built within a surface-oriented GDS by mapping a valid object directly accepted by any RP system without any influence on generative object creating. Through the involvement of Form Making processes of RP from selected instants with their solid phenomena, evidences are used for defending this viewpoint.Throughout the process, generative design method and CAD method have been utilized for the creation of virtual form. The 3D printer and Fused Deposition Modeling (FDM) technology with “trial and error” method were employed in the RP processes.

summary	Cooperative Atelier of Digital Simulation is a teaching proposal in that information technologies will be used intensively in the process of architectural design, particularly computer technologies for habitat simulation. In the first learning group, a experimental one - that should begin in the semester 2001.2, the computer will be used as an instrument for modeling, information management (spatial or not), making presentations, evaluation of alternatives and taking decisions, as well as for communication between the students’ teams and teachers of FAUFBA and, of other institutions that come to be integrating the project. The computer technologies could stand for the development of cooperative works. This paper synthesizes the proposal of creation of an optional discipline for students of Architecture and Urbanism.

title	Performance-based computational design via differential modeling and two-staged mapping
source	Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 667-680
summary	Computational performance-based building design support faces a conflict. It is important to provide building performance feed back to the designer as early as possible in the design process. But many aspects of building performance are significantly affected by the design of the building’s technical systems, which are typically configured in detail only in the later stages of design. The challenge is thus to find a method to use detailed simulation tools even during the early stages of design when values for many of the variables for the building’s technical sub-systems are not yet available. In this paper, we demonstrate how this problem can be partially solved by combining two levels of automation. The first level consists of differential building representation involving a number of domain (application-specific) object models that are derived from a shared object model automatically. The second level uses generative agents that create reference designs for the technical sub-systems of the building. To demonstrate the feasibility of the proposed approach, we use the building energy systems domain (heating, cooling, ventilation, and air-conditioning) as a case in point.

summary	The infusion of digital media into the practice of architecture is changing how we design as well as what we design. Digital media has altered the process of design and the culture of design education. The question before us is how does one transition from a completely analog system of representation to one of complete computer immersion or the “paperless studio”. Schools of Architecture have already begun to struggle with the physical issues of integration of new media (infrastructure and economics). But the pedagogical integration of new media should be of a greater concern. New media and its forms of representation are challenging traditional skills of communication and representation, (i.e., sketching, hand drawing and physical model making). The paradox facing architectural practice today is the integration of new media into a realm where traditional or manual forms of representation are ingrained into how we think, produce and communicate. We must ask ourselves, must new media be held to the traditional forms of representation?
