title	Geometric modeling: a survey
source	Computer Aided Design; 11: 253
summary	Computer programs are being developed to aid the design of physical systems ranging from individual mechanical parts to entire buildings or ships. These efforts highlight the importance of computer models of three dimensional objects. Issues and alternatives in geometric modelling are discussed and illustrated with comparisons of 11 existing modelling systems, in particular coherently-structured models of polyhedral solids where the faces may be either planar or curved. Four categories of representation are distinguished: data representations that store full, explicit shape information; definition languages with which the user can enter descriptions of shapes into the system, and which can constitute procedural representations; special subsets of the information produced by application programs; and conceptual models that define the logical structure of the data representation and/or definition language.

title	Curve and Surface Representations for Bezier B-spline Systems
source	1979? pp. 226- 236 : ill. includes bibliography
summary	The Bezier approach to the computer-aided design of surfaces, using interactive design of curves to construct surface sections, can be implemented using spline curves just as well as the original polynomial curves, and with some advantages. In the paper, some problems are considered that arise when a Bezier system is formulated and describe possible solutions for a spline-based system

title	Cybernetic Methodologies for Flexible and Generative Architectural Systems - the case of Fun Palace and Pattern Language
doi	https://doi.org/10.52842/conf.ecaade.2020.1.703
source	Werner, L and Koering, D (eds.), Anthropologic: Architecture and Fabrication in the cognitive age - Proceedings of the 38th eCAADe Conference - Volume 1, TU Berlin, Berlin, Germany, 16-18 September 2020, pp. 703-708
summary	The study focuses on early attempts to deal with complex physical environments through a comparative analysis of two canonic projects that combine architectural design with cybernetic theories: (1) "The Fun Palace", by British architect Cedric Price, 1962; and (2) "A Pattern Language", by architectural theorist Christopher Alexander, 1979. This study suggests that both projects dared to advance the relationship between architecture and cybernetics in order to create active reciprocity between architectural design and cybernetic system theories. Drawing on ideas and terms from systems theory, we suggest using a cybernetic system diagram to compare the two projects. We compare the work of Alexander and Price through the terminology of current technologies in order to better understand the reciprocity between the two fields. Such terms include feedback loop, optimization and translation processes, input and output, influence on the environment, automation and user interaction.

title	Personality assessment in regard to design strategies
source	Timmermans, Harry (Ed.), Design and Decision Support Systems in Architecture (Proceedings of a conference held in Mierlo, the Netherlands in July 1992), ISBN 0-7923-2444-7
summary	This paper discusses some preliminary results of several knowledge-acquisition and documentation-structuring techniques that were used to assess the working styles of architects. The focus of this assessment was on their strategic design behaviour. Hettema's Interactive Personality Model (Hettema 1979, 1989) was used to explain and interpret these results. The methods used to acquire the necessary data are protocol analysis, card sorting and interviews. The results suggest that at least three parameters can be used to explain and differentiate the strategic design behaviour of architects. These parameters are S (site-oriented), B (brief-oriented) and C (concept-oriented). A priority hierarchy of these parameters reveals six major distinguishable working styles. These results are captured in a new design model that can be used in data bank implementations.

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	Social Housing Mass Customization: Description of a system for real-time cost and spatial generation
source	Herrera, PC, Dreifuss-Serrano, C, Gómez, P, Arris-Calderon, LF, Critical Appropriations - Proceedings of the XXVI Conference of the Iberoamerican Society of Digital Graphics (SIGraDi 2022), Universidad Peruana de Ciencias Aplicadas, Lima, 7-11 November 2022 , pp. 53–64
summary	This study explores mass customization as an alternative strategy for social housing provision. The paper aims to demonstrate the implementation of an integrated system based on the connection between Building Information Modeling and algorithmic-parametric modeling technologies, seeking to design variability with real-time cost and time data control of single-family housing units. We developed the study according to five phases: (1) context analysis and design language definition; (2) rule-based design system definition; (3) cost and execution time estimation; (4) computer system based on the specified technologies definition; (5) quantitative evaluation and qualitative evaluation of the system. The experiment demonstrates that with the aid of algorithmic-parametric modeling, building information manipulation and visualization can be responsive enough to meet mass demands.

title	A Synergy of AI Observation and Design Tool: Leveraging Multifaceted AI Techniques for Encoding Human Behaviors and Stories in Space
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 502-516.
summary	This paper presents an innovative AI-powered tool aimed at revolutionizing observational methods in architectural design. Its primary objective is to bridge the existing gap between designers and AI predictions, streamlining and enhancing the design process. The tool facilitates the creation of dynamic visualizations that predict human behaviours within 3D design models, adapting seamlessly to design alterations. This prototype showcases the potential for efficient AI-assisted design. The core of our system consists of an AI model that trains on data related to human behavior within environmental contexts. Our user-friendly interface empowers designers to interact dynamically with their 3D modelling tool, akin to playing an interactive chess game. Designers can populate their models with human characters, and the system, in turn, predicts the likely activities of these characters. Observational techniques are pivotal in architectural design, drawing inspiration from influential works such as those by Alexander and Whyte. They provide a comprehensive understanding of how spaces can foster human interaction and help architects, designers, and urban planners make informed decisions that enhance user-friendliness. Nevertheless, two key challenges hinder the effective utilization of this data. Firstly, there is a lack of an intuitive interface that seamlessly integrates with existing tools. Designers often struggle to translate the information into design parameters and interpret the data effectively. Secondly, architects must adapt to evolving living environments and cultural shifts, necessitating real-time observations. However, time constraints and biases impede this process. A solution allowing designers to easily update their data is imperative. Our system comprises three integral components: a pre-trained model adaptable to specific locations, depth prediction and segmentation models for spatial comprehension, and a recognition model for user-designed structures. These features, combined with a user-friendly interface, empower designers to interact intuitively with their models, facilitating more informed and responsive design decisions.

title	Multilevel Analysis of Fire Escape Routes in a Virtual Environment
source	Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 331-342
summary	The paper discusses the computer-aided analysis and evaluation of fire safety in relation to pedestrian circulation in buildings, i.e., fire escape routes. It describes an approach employing both detailed and abstract representations. The goals of the research include: (a) the development of a pyramidal structure that links design analyses at different levels of abstraction; (b) the evaluation of abstract, normative levels of the analysis (and though these of underlying legal and professional principles) using the results of detailed, accurate simulations; and (c) the development a reliable framework for testing human behaviour in fire hazard.

title	Towards a Computational Description of Urban Patterns
doi	https://doi.org/10.52842/conf.ecaade.2008.239
source	Architecture in Computro [26th eCAADe Conference Proceedings / ISBN 978-0-9541183-7-2] Antwerpen (Belgium) 17-20 September 2008, pp. 239-248
summary	This study is concerned with the formulation of solutions for urban problems. It departs from Alexander’s pattern language theory and urban design guidelines, to create a system for generating specifications or the ingredients of a plan, given a scale, a site and a community. It takes into account strategies, regulations, guidelines, physical features of the site, and furthermore, the social, cultural and economic characteristics of the population. This system, sorted by a sequence of events, through stages, categories, methods and agents, describes taxonomic levels and their inner relations. Such an ontology provides a pattern encoding structure towards a computational model within the capabilities provided by the spatial data modeling of GIS (GIS-O). The urban formulation model is conceived to increase qualitative inputs, reducing ambiguities, through a flexible while automate process applied to urban planning.

title	Working Memory and Expertise Differences in Design.
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	The Creative Synthesis task devised by Finke and Slayton(1988) has been widely used as an experimental measure of mentalsynthesis, but previous studies have often failed to demonstrate anysignificant benefits of external support on participants’ performance.This paper discusses a study that examined novice and expert drawers’performance of synthesis using a modified stimuli set that was designedto increase the load on visuo-spatial working memory. The resultsshowed a significant increase in Transformational Complexity(Anderson & Hesltrup, 1993) of patterns produced by the expert groupwhile using sketching. It is argued that experts are more effective atusing sketching interactively to increase complexity, while novices relymore on using it as a simple memory aid.

summary	This paper describes the development of a Grasshopper-based planning support tool for urban planning. The tool aims at the analysis of demand in educational facilities and the optimization of their location and capacities. It was developed for the use case of Berlin using only publicly available resources and data sets. Through preprocessed GIS- and statistical data plus an easy-access interface, the tool encourages people from different backgrounds and even those with no professional knowledge in planning, to engage in urban decision making. Although being initially aimed at contributing to a moderated participation process, the tool's simple GUI (graphical user interface) and open source backend, make it usable in any setup - without a briefed advisor or the need for later professional evaluation by another party.

summary	This paper describes a system for searching and retrieving urban design drawings developed or contracted by public or governmental entities. We assume that in governmental public programs with similar goals recreating solutions is a daily action, which is, clearly, an unnecessary waste of time and resources. The system presented in this paper aims at concentrating and organizing this information in order to allow urban planners and designers to search for existing solutions to their projects and answers to their current needs.

source	International Journal of Architectural Computing vol. 12 - no. 4, 459-476
summary	This paper describes part of a wider research that aimed at using Shape Grammar to generate more diverse and interesting urban spaces in Brazilian Social Housing developments.A shape grammar corresponding to design patterns was inferred from the PREVI Lima urban plan developed by C.Alexander [1] in the 1970s.The grammar was inferred from the plan layout and from the text instructions (or pattern descriptions) presented by Alexander, and can be applied to design new plans within a wider formal universe than what the plan layout would suggest.The final section of the paper points towards the development of generic grammars as a way of encapsulating good qualities of certain design projects and applying them to new situations.

summary	A set of independent small grammars corresponding to design patterns were inferred from the PREVI Lima urban plan by C. Alexander. This pattern language composed of grammars inferred from the plan layout and grammars inferred from the text instructions (or pattern descriptions) written by Alexander can be applied to design new plans within a wider formal universe than what the plan layout would suggest.

summary	In 1976 Richard Foqué established periods in the development of methods of designing. The first stage (the 50's and early 60's) - automatization of the designing process - properly identified language of description that is understood by a machine is vital. Christopher Alexander publishes 'Pattern Language'. The second stage (late 60's) - the use of the Arts - research techniques as interview, questionnaire, active observation; ergonomic aspects are also taken into consideration. The third stage (starts at the turn of the 60's and 70's) - co-participation of all of the parties involved in the designing process, and especially the user. The designing process becomes more complex but at the same time more intelligible to a non-professional - Alexander's 'Pattern Language' returns. It's been over 20 years now since the publication of this work. In the mid 70's prototypes of integrate building description are created. We are dealing now with the next stage of the designing methods development. Unquestionable progress of computer optimalization of technical and economical solutions has taken place. It's being forecasted that the next stage would be using computer as a simulator of the designing process. This stage may be combined with the development of AI. (Already in 1950 Alan Turing had formulated the theoretical grounds of Artificial Intelligence.) Can the development of the AI have the influence on the creation of present time regional architecture? Hereby I risk a conclusion that the development of AI can contribute to the creation of modern regional architecture.

summary	This paper describes the semantics of action, an approach to describing input devices which allow the full utilization of all useful device characteristics and provides a high degree of hardware device independence. Part one discusses the semantics of graphical input device. The second shows how to create hierarchies of devices which provide a large measure of hardware independence. The third part applies these concepts to some typical problems, to demonstrate their completeness

summary	Quantitative studies using the corpus Google Ngram, namely Culturomics, have been analyzing the implicit patterns of culture changes. Being the top-standard prize in the field of Architecture since 1979, the Pritzker Prize has been increasingly diversified in the recent years. This study intends to reveal the implicit pattern of Pritzker Winners using the method of Culturomics, based on the corpus of Google Ngram to reveal the relationship of the sign of their fame and the fact of prize-winning. 48 architects including 32 awarded and 16 promising are analyzed in the printed corpus of English language between 1900 and 2008. Multiple regression models and multiple imputation methods are used during the data processing. Self-Organizing Map is used to define clusters among the awarded and promising architects. Six main clusters are detected, forming a 3×2 network of fame patterns. Most promising architects can be told from the clustering, according to their similarity to the more typical prize winners. The method of Culturomics could expand the sight of architecture study, giving more possibilities to reveal the implicit patterns of the existing empirical world.

title	Generating the Underlying Graphs for Architectural Arrangements
source	10 p. : ill. Pittsburgh: School of Urban and Public Affairs, Carnegie Mellon University, April, 1979. Research report No.79. Includes bibliography
summary	The mathematical correspondence to a floorplan is a Metric Planar Graph. Several methods for systematic direct generation of metric planar graphs have been developed including polyominoes, March and Matela and shape grammars. Another approach has been to develop a spatial composition in two separate steps. The first step involves discrete variables, and consists of enumerating a defined set of non-metric planar graphs. The second step involves spatial dimensions, e.g. continuous variables, and maps the graphs onto the Euclidean plane, from which a satisfactory or optimal one is selected. This paper focusses on the latter 2-step process. It presents a general method of solving the first step, that is the exhaustive enumeration of a set of planar graphs. The paper consists of three sections: The first section is an introduction to graph theory. The second section presents the generation of maximal planar graphs. The last section summarizes the presentation and comments on the appropriateness of the method
