title	Enhancing 3DSkyView Extension Performance
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-24088, p. 325-340
summary	This paper presents a second version of the 3DSkyView extension. The purpose of that extension was to implement a calculation algorithm for assessment and visualization of sky view factors (SVF) by means of tools available in a Geographical Information System (GIS). The sky view factor is a thermal and geometric parameter pointed out in the specialized literature as one of the main causes of urban heat islands. A 3D-GIS is a powerful tool for reaching the goal of this research because it allows the storage, treatment and analysis of tri-dimensional urban data, in addition to a high level of flexibility for incorporating calculation algorithms. The objective in the 3DSkyView extension is to optimize the determination of that factor, not only reducing its demanding calculation and graphical representation time, but also generating a simplified tool for replacing expensive photographic equipment usually applied on this matter. Enhancing functions of ArcView GIS 3.2, the first version of that extension showed a very good performance allowing the automatic delineation and determination of SVF. That performance was although limited to a single observer point. The simulation of SVF for several view points in urban canyons was only possible by applying the extension as many times as the number of observers considered. Therefore, this second version was now developed in order to allow simultaneous determination of SVF for many view points. In addition, the 3DSkyView new interface is more flexible, in a way that the user may choose the kind of output wanted (graphical and/or tabular). With this new feature it is then easier to create a continuous SVF map for an entire area.

title	What’s Happening to Architectural Sketching? - Interviewing architects about transformation from traditional to digital architectural sketching as a communicational tool with clients
doi	https://doi.org/10.52842/conf.ecaade.2022.1.389
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 389–398
summary	The paper discusses 23 interviewed architects in practice about the role of traditional and digital sketching (human-computer interaction) in communication with the client. They were selected from 1995 to 2018 (the interval of graduation) from three different countries: the Czech Republic (CR), Slovakia (SR), Netherland (NR). To realize three blending areas that impact the approach to sketching: (I) Traditional hand and physical model studies (1995-2003). (II)Transition form - designing by hand and PC (2004–2017). (III) Mainly digital and remote forms of designing (2018–now). Interviews helped transform 31 “parameters of tools use” from the previous theoretical framework narrowed down into six main areas: (1) Implementation; (2)Affordability; (3)Timesaving; (4) Drawing support; (5) Representativeness; (6) Transportability. Paper discusses findings from interviewees: (A) Implementation issues are above time and price. (B) Strongly different understanding of what digital sketching is. From drawing in Google Slides by mouse to sketching in Metaverse. (C) Substantial reduction of traditional sketching (down to a total of 3% of the time) at the expense of growing responsibilities. (D) 80% of respondents do not recommend sketching in front of the client. Also, other interesting findings are further described in the discussion.

title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

title	Delivery Types And Communication Modalities In The Flat-Pack Furniture Design Critic
source	T. Tidafi and T. Dorta (eds) Joining Languages Cultures and Visions: CAADFutures 2009 CD-Rom
summary	A computer-based design critiquing system analyzes a proposed solution and offers critiques (Robbins 1998). Critiques help designers identify problems as well as opportunities to improve their designs. Compared with human critics, today’s computer-based critiquing systems deliver feedback in quite restricted manner. Most systems provide only negative evaluations in text; whereas studio teachers critique by interpreting the student’s design, introducing new ideas, demonstrating and giving examples, and offering evaluations (Bailey 2004; Uluoglu 2000) using speech, writing, and drawing to communicate (Anthony 1991; Schön 1983). This article presents a computer-based critiquing system, Flat-pack Furniture Design Critic (FFDC). This system supports multiple delivery types and modalities, adapting the typical system architecture of constraint-based intelligent tutors (Mitrovic et al. 2007).

title	Environment – Urban Interface within Urban Growth
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 49-62
summary	This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title	An Evaluation of Neural Spatial Interaction Models Based on a Practical Application
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 19-32
summary	One of the serious problems faced by the Brazilian municipalities is the scarcity of resources for building education infrastructure. This asks for an optimal allocation of the available resources that includes, among other things, a rational spatial arrangement of the supply points (i.e., schools) in order to increase the demand coverage (i.e., students). If it is possible to foresee the regions where the demand is going to be concentrated, it is then possible to plan the location of new facilities and to assess the impact on the future level of service of the entire system. Considering that one of the consequences of the location-allocation process is the distribution of trips from demand points to supply points throughout the city, therefore affecting the overall intraurban accessibility conditions to essential services such as education, there is a strong need of models that planners can rely on to predict the future trip distribution patterns. As a result, the objective of this work was to evaluate the performance of Artificial Neural Networks (ANN) when applied to spatial interaction models, the so-called Neural Spatial Interaction Models. This was done in a practical context, in contrast to the more theoretical works commonly found in literature. The practical application showed that the neural spatial interaction model had different performances when compared to the traditional gravity models. In one case the neural models outperformed the gravity models, while on the other case it was just the opposite. The explanation for this may be in the data or in the ANN model formulation, as discussed in the conclusions.

title	Enseñanza de la representación manual y digital, para arquitectos y diseñadores [Teaching Hand and Digital Representation to Architects and Designers]
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	The supremacy of the digital means of representation and communication and the resulting shift of the manual means in the field of design and architecture, have engendered multiple opinions and literature. They focus and analyze the virtues and risks, the losses and substitutions, and the different expressive, productive and conceptual results of their leading role in the creative process. Furthermore, if we consider both as two extremes, apparently opposed, a broad panorama of combinations and additions are produced by the emerging group of hybrid practices. This motivated the development of a research project in the Universidad Nacional del Litoral de Santa Fe, Argentina, under the Program CAI+D 2000 dealing with Design and the Analog – Digital Means. From this project emerged a collection of conceptual speculations and experimentations in the extended field of representation, extended by the incorporation of new means and hybridations, searching for new parameters and methods for professional training and practice. Key words: analog, digital, graphics, means, representation.

title	Simulation of Micro Pedestrian Behaviour in Shopping Streets
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. 101-116
summary	Over the years, scholars have developed various models of pedestrian movement. These models can be used to assess the effects of detailed design decisions or to predict pedestrian behaviour under conditions of crowding. To date, not much attention has been paid to pedestrians' shopping behaviour at the micro level. Therefore, the main purpose of this project is to test a model that aims at simulating micro pedestrian behaviour in shopping streets, including entering shops. The model assumes a detailed network of links to represent the structure of street segments and entrances to the shops. The basic principle underlying the model is that a pedestrian moves from one link in the network to another, adjacent link. In fact, a pedestrian enters a segment at one side, heading for the other side of the segment. However, a pedestrian might enter the segment by leaving a shop as well. Then, the pedestrian might be heading for either side of the segment. While transferring from the current link to the next link, the pedestrian will be attracted by the shops along both sides of the street. The study area is Antwerp's main shopping street. During a one-week workshop in July 2004, students observed pedestrian movement in this shopping street. An inventory of some physical characteristics of the shopping street was made and pedestrians were tracked through two separate segments of the shopping street. In total, 334 pedestrians were tracked. A conventional multinomial logit model is used to simulate pedestrians' micro behaviour. The process of consecutively selecting links continues until the pedestrian has reached one of the terminal links or a shop. The model performs very well. Simulated routes were used to assess the validity of the model. Observed and simulated link loading correspond fairly well, however, the model seems to slightly mispredict the attraction of a number of shops.

title	Using a Spatial Microsimulation Decision Support System for Policy Scenario Analysis
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Recent Advances in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Kluwer Academic Publishers, ISBN: 1-4020-2408-8, p. 177-191
summary	This paper discusses the potential of a spatial microsimulation-based decision support system for policy analysis. The system can be used to describe current conditions and issues in neighbourhoods, predict future trends in the composition and health of neighbourhoods and conduct modelling and predictive analysis to measure the likely impact of policy interventions at the local level. A large dynamic spatial micro-simulation model is being constructed for the population of Leeds (approximately 715,000 individuals) based on spatial microsimulation techniques in conjunction with a range of data, including 2001 Census data for Output Areas and sample data from the British Household Panel Survey. The project has three main aims as follows: (i) to develop a static microsimulation model to describe current conditions in Leeds; (ii) to enable the performance of ‘What if?’ analysis on a range of policy scenarios; and (iii) to develop a dynamic microsimulation model to predict future conditions in Leeds under different policy scenarios. The paper reports progress in meeting the above aims and outlines the associated difficulties and data issues. One of the significant advantages of the spatial microsimulation approach adopted by this project is that it enables the user to query any combination of variables that is deemed desirable for policy analysis. The paper will illustrate the software tool being developed in the context of this project that is capable of carrying out queries of this type and of mapping their results. The decision support tool is being developed to support policy-makers concerned with urban regeneration and neighbourhood renewal.

summary	We are presenting design ideas, technical innovation, and fabrication expertise that address crucial issues. Authors investigate how to effectively design and practice architecture with automated prototyping and manufacturing. We want to understand where this might lead, and how it might change the nature of architecture itself. We are just beginning to discover the opportunities to be found in integrating automated fabrication within the practice of architecture. At the same time, the new century has brought very mixed perspectives on confident Modern progress. A cautious scrutiny of 'innovation' is needed. Fabrication is an old word with the straightforward meaning, to make. The roots of the word lead to the origins of architecture. Making has been considered a virtue by ancient writers and modern politicians alike. Fabrication (and homo faber, 'one who makes') have served as fundamental terms that constitutions and contract laws have been built upon. Shaping and working with materials is at the core of Western civilization. However at a point in human history where nature is steadily being replaced by human artifice, the consequences of making are far from simple. Whether for good or ill, our new fabricated environment is transforming the world.

title	COMPUTER DESIGN OF REPEATING HYPERBOLIC PATTERNS
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 83-90.
summary	From antiquity, humans have created 2-dimensional art on flat surfaces (the Euclidean plane) and on surfaces of spheres. However, it wasn't until about 50 years ago that designers have created art in the third "classical geometry", the hyperbolic plane. Inspired by a diagram from the mathematician H. S. M. Coxeter, the graphic artist M. C. Escher became the first person to design such patterns, performing all the needed constructions laboriously by hand. In order to exhibit the true hyperbolic nature of such art, the pattern must exhibit symmetry and repetition. It seems natural to use a computer to avoid the tedious hand constructions performed by Escher. This was our goal: to design and implement a computer program to create repeating hyperbolic patterns.

title	MORPHOGENESIS – EVOLUTION OF SHAPE; IMAGINATION AMPLIFIER VERSION 1.0
source	ETH postgraduate studies final thesis, Zurich
summary	The advent of computer technologies in the design-processes has already taken place, is meanwhile ordinary. New design perspectives are opened, and an almost inexhaustable form repertoire is available, even buildable - ‘Nothing is impossible‘. This thesis work deals only with a small clip from there. Essentially it consists of two parts: » MORPHOGENESIS – Evolution of Shape « describes the present situation of generating shape with the help of computers. Some of the technologies that are used for, as comupter-morphing or evolutionary programming, are examined more closely here. »IMAGINATION AMPLIFIER Version 1.0« is an interactive Form-Generator for houses - a House-Machine. The program deals with the possibilities of interpolation and morphing between two, 3 dimensional, states (Startand Target-House) configured by the user. As an output–result, the generator depicts the put in number of steps in between, with characteristic values like cubical contents (V), surface quadrature (A) and the relation between V/A. All the results are stored in a database, where it is possible to select from for new morphing operations, to get in the end closer to a more optimized shape.

summary	The project deals with supplementation of fine art components to the newly designed square in front of the main railway station and their integration into the public space to provide a good system functioning in the contemporary ground-floor level. Several students of Faculty of Architecture, Slovak University of Technology in Bratislava, have elaborated this idea under the leadership of B. Kubinsky with the technical support of P. Kardos during the years 2001 and 2002. The supplementation had been planned in two parts: first each student has designed his own object of art and created the model of his piece. Then, in the second part, the quality and relevance of each object was verified by the spatial endoscope in the laboratory of P. Kardos.

summary	Immersive virtual environments have received widespread attention as providing possible replacements for the media and systems that designers traditionally use, as well as, more generally, in providing support for collaborative work. Relatively little attention has been given to date however to the problem of how to merge immersive virtual environments into real world work settings, and so to add to the media at the disposal of the designer and the design team, rather than to replace it. In this paper we report on a research project in which optical see-through augmented reality displays have been developed together with prototype decision support software for architectural and urban design. We suggest that a critical characteristic of multi user augmented reality is its ability to generate visualisations from a first person perspective in which the scale of rendition of the design model follows many of the conventions that designers are used to. Different scales of model appear to allow designers to focus on different aspects of the design under consideration. Augmenting the scene with simulations of pedestrian movement appears to assist both in scale recognition, and in moving from a first person to a third person understanding of the design. This research project is funded by the European Commission IST program (IST-2000-28559).

summary	This paper examines the development of a prototype suite of on-line integrated multimedia-GIS tools to assist in bottom up decision-making. These tools are being developed in the context of scenario planning to enable the community to actively explore different land use options and the implication of government structure and strategic plans. A case study approach is undertaken, focusing on the Jewell Station Neighbourhood, situated in the City of Moreland, Greater Melbourne Region, Australia. The paper documents the first stage of the project, in developing three land use scenarios delivered through a range of technologies including: VRML, HTML, GIS, Pixmaker and Flash. The paper concludes by outlining the future directions of this research that include: the construction of a virtual sandbox, usability testing, and community consultation.

title	The Project Planning of Urban Decongestion

summary	This study introduces a methodology for the evaluation, among a set of possible plans and/or policies, of a transport system which could reduce the effects of the network congestion on an urban area. Hence it is proposed a procedure which contains a new element compared with the current methodologies that is the final user’s evaluation of the examined system by turning to the application of the contingent valuation method, a technique like stated preferences. The approach we propose is based on the necessity for a determination of an optimal solution to the urban congestion to be established on the politic acceptability by the final user. Solutions which result virtually feasible for a public administration both on a technique and economic point of view often meet hostility by individuals. Consequently, it would be interesting for policy makers to adopt a process of valuation which could let to understand the user’s sensitivity and hostility towards specific configurations of the system, chosen as solution to decongestion (traffic calming, roadpricing, auto-free zones) and consequently to make less unpleasant the strategy to be carried out to control congestion (Harrington et al., 2001). In this way, a user does not judge the implementation of a set of projects made by a decision-maker as imposition and he is willing to pay in order to fulfil the chosen scenario. Finally we describe an application of the proposed methodology relating the definition of the integrated transport system in the metropolitan area of Bari, chief town of Apulia.

title	Applying Genetic Algorithms to Establish Disaster Decision Support System for Flooding Evacuation Path of Hsichih Area in Taiwan
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 63-75
summary	Because of the special geography features and subtropics weather in Taiwan, we need to provide correct information to help people making decision when they are in disaster. So the disaster decision support system must offer proper information of evacuation path to people. This research has shown the difficulties associated with the GIS and the flooding evacuation path search through the huge searching space generated during the network analysis process. This research also presents an approach to these problems by utilizing a search process whose concept is derived from natural genetics. Genetic algorithms (GAs) have been introduced in the optimization problem solving area by Holland (1975) and Goldberg (1989) and have shown their usefulness through numerous applications. We apply GA and GIS to choice flooding evacuation path in metropolitan area in this study. We take the region of Shiji city in Taiwan for case. Firstly, we establish the node relationship of GA calculation, the level of the weight is the standard of the date that is exported by Disaster Database. Secondly, we apply GA to calculate different evacuation path in different time series. Finally, we build the model of choosing flooding evacuation path.

title	Design Generation of the Central Asian Caravanserai
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	Challenges for the study of Islamic architecture include its abundance and diversity in expression and its classification based on distinct functional or stylistic types. We address these issues by presenting shape grammars as a methodology for the analysis and design generation of Islamic architecture, with a specific example in the form of a parametric shape grammar for central Asian caravanserais. The grammar is developed by identifying distinct design types. Shape rules are created based on a study of the spatial elements and their organisation in the designs. We illustrate the utility of the grammar by deriving an extant design and as well as, previously unknown designs. We conclude by discussing possible extensions to the current grammar and future work involving the development of a grammar based framework for the comparative analysis of medieval Islamic courtyard buildings.
