title	Architecture: Form, Space and Order
source	Van Nostrand Reinhold. New York
summary	The Second Edition of this classic introduction to the principles of architecture is everything you would expect from the celebrated architect, author, and illustrator, Francis D. K. Ching. Each page has been meticulously revised to incorporate contemporary examples of the principles of form, space, and order-the fundamental vocabulary of every designer. The result is a beautifully illustrated volume that embraces today's forms and looks at conventional models with a fresh perspective. Here, Ching examines every principal of architecture, juxtaposing images that span centuries and cross cultural boundaries to create a design vocabulary that is both elemental and timeless. Among the topics covered are point, line, plane, volume, proportion, scale, circulation, and the interdependence of form and space. While this revision continues to be a comprehensive primer on the ways form and space are interrelated and organized in the shaping of our environment, it has been refined to amplify and clarify concepts. In addition, the Second Edition contains: * Numerous new hand-rendered drawings * Expanded sections on openings and scale * Expanded chapter on design principles * New glossary and index categorized by the author * New 8 1/2 ? 11 upright trim In the Second Edition of Architecture: Form, Space, and Order, the author has opted for a larger format and crisper images. Mr. Ching has retained the style of his hand-lettered text, a hallmark of each of his books. This rich source of architectural prototypes, each rendered in Mr. Ching's signature style, also serves as a guide to architectural drawing. Doubtless, many will want this handsome volume for the sheer beauty of it. Architects and students alike will treasure this book for its wealth of practical information and its precise illustrations. Mr. Ching has once again created a visual reference that illuminates the world of architectural form.

title	3D Visualization in Design Education
source	Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 177-184

summary	It has been said that "The beginning of architecture is empty space." (Mitchell 1990) This statement typifies a design education philosophy in which the concepts of space and form are separated and defined respectively as the negative and positive of the physical world, a world where solid objects exist and void-the mere absence of substance-is a surrounding atmospheric emptiness. Since the beginning of the nineteenth century, however, there has been an alternative concept of space as a continuum: that there is a continuously modified surface between the pressures of form and space in which the shape of the space in our lungs is directly connected to the shape of the space within which we exist. (Porter 1979). The nature of the task of representing architecture alters to reflect the state of architectural understanding at each period of time. The construction of architectural space and form represents a fundamental achievement of humans in their environment and has always involved effort and materials requiring careful planning, preparation, and forethought. In architecture there is a necessary conversion to that which is habitable, experiential, and functional from an abstraction in an entirely different medium. It is often an imperfect procedure that centers on the translation rather than the actual design. Design of the built environment is an art of distinctions within the continuum of space, for example: between solid and void, interior and exterior, light and dark, or warm and cold. It is concerned with the physical organization and articulation of space. The amount and shape of the void contained and generated by the building create the fabric and substance of the built environment. Architecture as a design discipline, therefore, can be considered as a creative expression of the coexistence of form and space on a human scale. As Frank Ching writes in Architecture: Form, Space, and Order, "These elements of form and space are the critical means of architecture. While the utilitarian concerns of function and use can be relatively short lived, and symbolic interpretations can vary from age to age, these primary elements of form and space comprise timeless and fundamental vocabulary of the architectural designer." (1979)

title	Visual and Spatial Analysis in Office Design
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	The demands for rapid response to complex problems, flexibility, and other characteristics of today's workplace, such as a highly trained work force, have led many organizations to move from strict hierarchical structures to a more flexible project team organization. The organizational structure is broader and flatter, with greater independence given to organizational units, in this case the project teams. To understand the relationship between project team communication patterns and the design and layout of team space, a study was conducted of an architectural office before and after a move to new space. The study involved three project teams. Information was collected on individual communication patterns; perceptions of the ease of communication; and the effectiveness of the design and layout of physical space to support these communications. In order to provide guidance for critical decision-making in design, these communication data were correlated with a series of measures for the specification of team space enclosure and layout. These group/team space measures were adaptations of existing measures of individual work space, and included an enclosure measure, based on an enclosure measure developed by Stokols (1990); a measure of visual field, based on the "isovist" fields of Benedikt (1979); and an "integration" measure, based on the work of Hillier and Hanson (1984). Results indicate both linear and non-linear relationships between interaction patterns and physical space measures. This work is the initial stage of a research program to define a set of specific physical measures to guide the design of supportive work space for project teams and work groups within various types of organizations.

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

title	Spacemaker : A Computer Language for Modelling Architectural Physical Form
source	Application of Computers in Architecture, Building Design and Urban Planning, International Conference Proceedings. 1979. pp. 573-582 : ill. includes bibliography
summary	The paper describes a modeling technique of architectural form. The technique is divided into two parts. A diagrammatic production system and a computer language. The production notation serves as a representation of underlying organization of building groups. The computer language -- SPACEMAKER -- facilitates the coding of such rules for computer programming. The particular version of the diagrammatic production system as presented first began by attempting to apply two picture grammars to architectural problems. The first effort was based on PDL developed by Allen Shaw and was called SNARQ I and the second one grew out of work done by Yun-chung Cho and was called SNARQ II. A few years later, these notations evolved into the notation presented after adapting ideas from A. Lindenmeyer. Numerous models of architectural systems were then constructed

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
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	Gentrification Waves in the Inner-City of Milan - A multi agent / cellular automata model based on Smith's Rent Gap theory
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 187-201
summary	The aim of this paper is to investigate the gentrification process by applying an urban spatial model of gentrification, based on Smith's (1979; 1987; 1996) Rent Gap theory. The rich sociological literature on the topic mainly assumes gentrification to be a cultural phenomenon, namely the result of a demand pressure of the suburban middle and upper class, willing to return to the city (Ley, 1980; Lipton, 1977, May, 1996). Little attempt has been made to investigate and build a sound economic explanation on the causes of the process. The Rent Gap theory (RGT) of Neil Smith still represents an important contribution in this direction. At the heart of Smith's argument there is the assumption that gentrification takes place because capitals return to the inner city, creating opportunities for residential relocation and profit. This paper illustrates a dynamic model of Smith's theory through a multi-agent/ cellular automata system approach (Batty, 2005) developed on a Netlogo platform. A set of behavioural rules for each agent involved (homeowner, landlord, tenant and developer, and the passive 'dwelling' agent with their rent and level of decay) are formalised. The simulations show the surge of neighbouring degradation or renovation and population turn over, starting with different initial states of decay and estate rent values. Consistent with a Self Organized Criticality approach, the model shows that non linear interactions at local level may produce different configurations of the system at macro level. This paper represents a further development of a previous version of the model (Diappi, Bolchi, 2005). The model proposed here includes some more realistic factors inspired by the features of housing market dynamics in the city of Milan. It includes the shape of the potential rent according to city form and functions, the subdivision in areal submarkets according to the current rents, and their maintenance levels. The model has a more realistic visualisation of the city and its form, and is able to show the different dynamics of the emergent neighbourhoods in the last ten years in Milan.

title	Efficiency of Model Endoscopic Simulation - An Experimental Research at the University of Stuttgart
source	Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 31-34
summary	At the Institute of Urban Planning at the University of Stuttgart early experiments were made with the help of endoscopes in the late 1970’s. The intention was to find new instruments to visualize urban design projects. The first experiment included the use of a 16 mm film of a 1:170 scale model of the market place at Karlsruhe, including design alternatives (with trees, without trees etc). The film was shown to the Karlsruhe authorities, who had to make the decision about the alternatives. It was said, that the film gave a great help for the decision-making and a design proposition had never before been presented in such understandable way. In 1975-77, with the support of the Deutsche Forschungsgemeinschaft (German Research Foundation) an investigation was carried out into existing endoscopic simulation facilities, such as those in Wageningen, Lund and Berkeley. The resulting publication was mainly concerned with technical installations and their applications. However a key question remained: ”Can reality be simulated with endoscopy?” In 1979-82, in order to answer that question, at the Institute was carried out the most extensive research of the time, into the validity of endoscopic simulation. Of special importance was the inclusion of social scientists and psychologists from the University of Heidelberg and Mannheim. A report was produced in 1983. The research was concerned with the theory of model simulation, its ways of use and its users, and then the establishment of requirements for effective model simulation. For the main research work with models or simulation films, psychological tests were developed which enabled a tested person to give accurate responses or evidence without getting involved in alien technical terminology. It was also thought that the use of semantic differentials would make the work imprecise or arbitrary.

title	Dislocations of the spatial experience: From earthwork to liquid architecture [Deslocamentos da experiência espacial: De earthwork a arquitetura líquida]
source	SIGraDi 2007 - [Proceedings of the 11th Iberoamerican Congress of Digital Graphics] México D.F. - México 23-25 October 2007, pp. 423-427
summary	This article reflects about the contemporary notion of “spatial experience” that can be drawn by means of the emergence of the “expanded field” in arts (Rosalind Krauss, 1979). For a perspective view of this notion and for its problematization in the current time we pretend to stablish a counterpoint between two historic moments related to the expansion of the spatial field and its experience: the 1960´s, with the focus on the immanent space by artistic propositions, and nowadays, with the ocurrence of “fusional fields” of art-architecture-landscape-digital media. We adopt as strategy to construct the question, the approximation of two paradigmatic works for their respective epochs: the “earthwork” Spiral Jetty of Robert Smithson, constructed in 1970 in the Great Salt Lake (Utah, USA) and the ephemeral architecture of Blur Building of Elizabeth Diller and Ricardo Scofidio, constructed in 2002 in the Lake Neuchatel, for the Suiss Expo (Yverdon-les-Bains – Suiss).

title	Parallel Processing Techniques for Hidden Surface Removal
source	SIGGRAPH '79 Conference Proceedings. 1979. vol. 13 ; no. 2: pp. 300-307 : ill. includes bibliography
summary	Previous work in the hidden-surface problem has revealed two key concepts. First, the removal of non-visible surfaces is essentially a sorting problem. Second, some form of coherence is essential for the efficient solution of this problem. In order to provide real-time simulations, it is not only the amount of sorting which must be reduced, but the total time required for computation. One potentially economic strategy to attain this goal is the use of parallel processor systems. This approach implies that the computational time will no longer be dependent on the total amount of sorting, but more on the appropriate division of responsibility. This paper investigates two existing algorithmic approaches to the hidden-surface problem with a view towards their applicability to implementation on a parallel machine organization. In particular, the statistical results of a parallel processor implementation indicate the difficulties stemming from a loss of coherence and imply potentially important design criteria for a parallel configuration

summary	A building comprises of more than the skin and the structural works. It is the soul that comes in the form of SPACE that is intriguing and provokes the mind. To be able to experience a building relies heavily on the spatial concept and internal lay out. How one is captured right from entering the entrance and through the layering of space, of horizontal and vertical planes and finally the euphoria, or depressed feeling that concludes the tour depending on the feeling intended (Miller, 1995). The common norm at present celebrates the outer skin and grandeur of facades. Not many include the hidden grids and fragmentation that can lead to a surprisingly good form AND space. Thus a number of them fail, in the sense of a sensuous building. ‘The circulation path can be conceived as the perceptual thread that links the spaces of a building or any series of interior or exterior spaces, together. Since we move in TIME, through SEQUENCE of SPACES, we experience a space in relation to where we’ve been, and where we anticipate going’ (Ching, 1979). This research intends to study and analyze the unconventional electronic gallery or ‘e-gallery’ as a versatile hybrid container. The focus of the research will be on documenting spaces in the e-gallery, bringing to light the unlimited possibilities that can take place in such a space.

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	Building community: a new future for architecture education and practice
source	Carnegie Foundation for the Advancement of Teaching
summary	Internships, before and after graduation, are the most essential link connecting students to the world of practice. Yet, by all accounts, internship is perhaps the most troubled phase of the continuing education of architects. During this century, as architectural knowledge grew more complex, the apprenticeship system withered away and schools assumed much of the responsibility for preparing architects for practice. However, schools cannot do the whole job. It is widely acknowledged that certain kinds of technical and practical knowledge are best learned in the workplace itself, under the guidance of experienced professionals. All state accrediting boards require a minimum period of internship-usually about three years-before a person is eligible to take the licensing exam. The National Council of Architectural Registration Boards (NCARB) allows students to earn up to two years of work credit prior to acquisition of an accredited degree. The Intern Development Program (IDP), launched by NCARB and the American Institute of Architects in 1979, provides the framework for internship in some forty states. The program was designed to assure that interns receive adequate mentoring, that experiences are well-documented, and that employers and interns allocate enough time to a range of educational and vocational experiences to prepare students for eventual licensure. As the IDP Guidelines state, "The shift from school to office is not a transition from theory to pragmatism. It is a period when theory merges with pragmatism.... It's a time when you: apply your formal education to the daily realities of architectural practice; acquire comprehensive experience in basic practice areas; explore specialized areas of practice; develop professional judgment; continue your formal education in architecture; and refine your career goals." Whatever its accomplishments, however, we found broad consensus that the Intern Development Program has not, by itself, solved the problems of internship. Though we found mutually satisfying internship programs at several of the firms we visited or heard about around the country, at many others interns told us they were not receiving the continuing education and experience they needed. The truth is that architecture has serious, unsolved problems compared with other fields when it comes to supplying on-the-job learning experiences to induct students into the profession on a massive scale. Medicine has teaching hospitals. Beginning teachers work in actual classrooms, supported by school taxes. Law offices are, for the most part, in a better financial position to support young lawyers and pay them living wages. The architecture profession, by contrast, must support a required system of internship prior to licensure in an industry that has neither the financial resources of law or medicine, the stability and public support of teaching, nor a network of locations like hospitals or schools where education and practice can be seamlessly connected. And many employers acknowledged those problems. "The profession has all but undermined the traditional relationship between the profession and the academy," said Neil Frankel, FAIA, executive vice president of Perkins & Will, a multinational firm with offices in New York, Chicago, Washington, and London. "Historically, until the advent of the computer, the profession said, 'Okay, go to school, then we in the profession will teach you what the real world is like.' With the coming of the computer, the profession needed a skill that students had, and has left behind the other responsibilities." One intern told us she had been stuck for months doing relatively menial tasks such as toilet elevations. Another intern at a medium-sized firm told us he had been working sixty to seventy hours per week for a year and a half. "Then my wife had a baby and I 'slacked off' to fifty hours. The partner called me in and I got called on the carpet for not working hard enough." "The whole process of internship is being outmoded by economics," one frustrated intern told us. "There's not the time or the money. There's no conception of people being groomed for careers. The younger staff are chosen for their value as productive workers." "We just don't have the best structure here to use an intern's abilities to their best," said a Mississippi architect. "The people who come out of school are really problems. I lost patience with one intern who was demanding that I switch him to another section so that he could learn what he needed for his IDP. I told him, 'It's not my job to teach you. You are here to produce.'" What steps might help students gain more satisfying work opportunities, both during and after graduation?

title	Architectural Innovation as an evolutionary process
source	International Conference on Generative Art
summary	Traditionally in art and architectural history, innovation is treated as a history of ideas of individuals (pioneers), movements and schools. The monograph is in that context one of the most used forms of scientific exercise. History of architecture is then mostly seen as a succession of dominant architectural paradigms imposed by great architectural creators fighting at the beginning against mainstream establishment until they themselves come to be recognised. However, there have been attempts to place architectural innovation and creativity in an evolutionary perspective. Charles Jencks for example, has described the evolution of architectural and art movements according to a diagram inspired by ecological models. Philip Steadman, in his book "The Evolution of Designs. Biological analogy in architecture and the applied arts" (1979), sketches the history of various biological analogies and their impact on architectural theory: the organic, classificatory, anatomical, ecological and Darwinian or evolutionary analogies. This last analogy "explains the design of useful objects and buildings, particularly in primitive society and in the craft tradition, in terms of a sequence of repeated copyings (corresponding to inheritance), with small changes made at each stage ('variations'), which are then subjected to a testing process when the object is put into use ('selection')." However, Steadman has confined his study to a literature survey as the basis of a history of ideas. Since this pioneering work, new developments like Dawkins' concept of memes allow further steps in the field of cultural evolution of architectural innovation. The application of the concept of memes to architectural design has been put forward in a preceding "Generative Art" conference (Daru, 1999), showing its application in a pilot study on the analysis of projects of and by architectural students. This first empirical study is now followed by a study of 'real life' architectural practice. The case taken has a double implication for the evolutionary analogy. It takes a specific architectural innovative concept as a 'meme' and develops the analysis of the trajectory of this meme in the individual context of the designer and at large. At the same time, the architect involved (Eric Vreedenburgh, Archipel Ontwerpers) is knowledgeable about the theory of memetic evolution and is applying a computer tool (called 'Artificial') together with Remko Scha, the authoring computer scientist of the program who collaborates frequently with artists and architects. This case study (the penthouse in Dutch town planning and the application of 'Artificial') shall be discussed in the paper as presented. The theoretical and methodological problems of various models of diffusion of memes shall be discussed and a preliminary model shall be presented as a framework to account for not only Darwinian but also Lamarckian processes, and for individual as well as collective transmission, consumption and creative transformation of memes.

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	An Algorithm for Shading of Regions on Vector Display Devices

summary	The display of shaded polygons by line, cross-hatch, and dot patterns on vector devices is a task frequently used in computer graphics and computer cartography. In applications such as the production of shaded maps polygon shading turns out to be critical with respect to time requirements, and the development of efficient algorithms is of importance. Given an arbitrary polygon in the plane without self-crossing edges (simply-connected polygon), the task at hand is to shade this polygon with one or two sets of parallel lines where for each set a shading angle and a line distance are given. The basic concept of this new algorithm is to decompose the polygon into a set of mutually exclusive trapezoids (in special cases triangles) where the parallel edges of the trioxides are parallel to the desired shading lines. These trapezoids and triangles are then shaded in a fast procedure. In its present form the algorithm handles regions with up to 300 islands. Possible extensions include the construction of dash and cross patterns

title	Computer Graphics for Large Scale Two- and Three-Dimensional Analysis of Complex Geometries
source	SIGGRAPH '79 Conference Proceedings. August, 1979. vol. 13 ; no. 2: pp. 33-40 : ill. includes bibliography
summary	A comprehensive set of programs have been developed for analysis of complex two- and three- dimensional geometries. State of the art finite element and hydrodynamic codes are being used for the analytical portion of the work. Several additional codes depending heavily on graphics have been developed to assist the analytical effort. These are basically used for the pre- and post-processing of the data. Prior to running any analysis, the geometry of the body of interest must be represented in the form of small 'finite elements.' After the analysis is run, the data must be post-processed. Both spatial and temporal data exist in the database. It is the database between the analysis codes and the post- processors which allows a wide variety of analysis codes to use the same post-processors. The temporal plotting codes produce time histories for specified quantities (i.e. temperature, pressure, velocity, stress, etc.) at various locations within the body. They may also produce cross-plots of these variables (i.e. stress vs. strain at a particular position). One of the two codes used for plotting of the spatial data is for two-dimensional geometries and the other for three-dimensional models. For three dimensions, the Watkins' hidden surface / line processor is utilized for plots. The spatial plotters display contour lines on vector output devices and color fringes (or gray values) on raster output devices. They both may also display deformed geometries. Further the three-dimensional code has extensive animation capabilities for movie productions
