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	Predetermining Visibility Priority in 3-D Scenes
source	SIGGRAPH '79 Conference Proceedings. August, 1979. vol. 13 ; no. 2: pp. 175-181 : ill. includes bibliography
summary	The principal calculation performed by all visible surface algorithms is the determination of the visible polygon at each pixel in the image. Of the many possible speedups and efficiencies found for this problem, only one published algorithm (developed almost a decade ago by a group at General Electric) took advantage of an observation that many visibility calculations could be performed without knowledge of the eventual viewing position and orientation -- once for all possible images. The method is based on a 'potential obscuration' relation between polygons in the simulated environment. Unfortunately, the method worked only for certain objects; unmanageable objects had to be manually (and expertly!) subdivided into manageable pieces. Described in this paper is a solution to this problem which allows substantial a-priori visibility determination for all possible objects without any manual intervention. The method also identifies the (hopefully, few) visibility calculations which remain to be performed after the viewing position is specified. Also discussed is the development of still stronger solutions which could further reduce the number of these visibility calculations remaining at image generation time

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	An Algorithmic Approach to Controlling Search in Three-Dimensional Image Data
source	SIGGRAPH '79 Conference Proceedings. August, 1979. vol. 13 ; no. 2: pp. 134- 141 : ill. includes bibliography
summary	In many three-dimensional imaging applications random shaped objects, reconstructed from serial sections, are isolated to display their overall structure in a single view. This paper presents an algorithm to control an ordered search strategy for locating all contours of random shaped objects intersected by a series of cross-section image planes. Classic search techniques in AI problem solving and software for image processing and computer graphics are combined here to aid program initialization and automate the search process thereafter. Using three-dimensional region growing, this method isolates all spatially connected pixels forming a structure's volume and enters image planes the least number of times to do so. An algorithmic description is given to generalize the process for controlling search in 3-D image data where little core memory is available. Phantom and medical computer tomographic data are used to illustrate the algorithm's performance

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	Three-dimensional Visualization: A Case Study
source	Computer-Aided Architectural Design Futures [CAAD Futures Conference Proceedings / ISBN 0-408-05300-3] Delft (The Netherlands), 18-19 September 1985, pp. 92-102
summary	Three-dimensional computer visualization has intrigued both building designers and computer scientists for decades. Research and conference papers present an extensive list of existing and potential uses for threedimensional geometric data for the building industry (Baer et al., 1979). Early studies on visualization include urban planning (Rogers, 1980), treeshading simulation (Schiler and Greenberg, 1980), sun studies (Anon, 1984), finite element analysis (Proulx, 1983), and facade texture rendering (Nizzolese, 1980). With the advent of better interfaces, faster computer processing speeds and better application packages, there had been interest on the part of both researchers and practitioners in three-dimensional -models for energy analysis (Pittman and Greenberg, 1980), modelling with transparencies (Hebert, 1982), super-realistic rendering (Greenberg, 1984), visual impact (Bridges, 1983), interference clash checking (Trickett, 1980), and complex object visualization (Haward, 1984). The Division of Building Research is currently investigating the application of geometric modelling in the building delivery process using sophisticated software (Evans, 1985). The first stage of the project (Vanier, 1985), a feasibility study, deals with the aesthetics of the mode. It identifies two significant requirements for geometric modelling systems: the need for a comprehensive data structure and the requirement for realistic accuracies and tolerances. This chapter presents the results of the second phase of this geometric modelling project, which is the construction of 'working' and 'presentation' models for a building.

title	Lost In Hyperspace: Cognitive Mapping and Navigation in a Hypertext Environment, Chapter 7
source	Hypertext: Theory Into Practice, Edited by McAleese, Ray., Ablex Publishing Corporation, New Jersey
summary	This paper describes an experiment which looks at how the users of a hypertext document cognitively represent its layout. A document was formed into three different hypertext styles and was presented to the readers, they were then asked a series of questions about information contained in the hypertexts. The way the users found the answers and the time taken was recorded, they were also ask to lay out cards, with reduced versions of the screen on them, on a board and as they thought them to be arranged in the document and also to draw any connecting hypertext links they thought existed between these screens. The users selected for this experiment consisted of 27 university undergraduates 15 male and 12 female with a mean age of 20.5 years with little or no computing experience. They were each assigned one of the three hypertext methods and their performance was recorded. The three methods consisted of a hierarchical, a mixed and an index based method.

summary	In this paper we report on ongoing research in which the implications of urban scale pervasive computing (always and everywhere present) are investigated for urban life and urban design in the heritage environment of the city of Bath. We explore a theoretical framework for understanding and designing pervasive systems as an integral part of the urban landscape. We develop a framework based on Hillier's Space Syntax theories and Kostakos' PSP framework which encompasses the analysis of space and spatial patterns, alongside the consideration of personal, social and public interaction spaces to capture the complex relationship between pervasive systems, urban space in general and the impact of the deployment of pervasive systems on people's relationships to heritage and to each other. We describe these methodological issues in detail before giving examples from early studies of the types of result we are beginning to find.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 24-32.
summary	Text-to-image generators, such as Midjourney, DALL-E, and Stable Diffusion, are becoming increasingly popular. These generators, whose models are trained on large datasets of text-image pairs, often scraped from the web, take text prompts as input, and use them to generate images—text-to-image prompting. In this visual essay, we raise questions about the entanglement of semiotics, semantics, syntax, and society in these text-to-image generator tools. We are intrigued by how these technologies are “intrawoven” with social and cultural contexts. How are their constructions and presentations reconfigurations? How do, or might they, inform pedagogy, theory, methods, and our publics? To explore these questions, we entered six prompts related to the built environment in six different languages, eight months apart in Midjourney (“Midjourney” n.d.). The generated images (Figure 1), require that we ask deep questions of each image, in comparison with each other, across each group of four, and across time (eight months apart). We argue that text-to-image generators call for a rigorous exploration of semiotics, semantics, syntax, and the society, with implications for pedagogy, theory-building, methodologies, and public enlightenment. Furthermore, we assert that these tools can facilitate pertinent questions about the relationships between technology and society. This is just the beginning. For now, we have questions.

summary	In this paper we present an outline of a newly started project to develop a tool which connects BIM to a manufacturing technique like 3D printing. First we will look some promising manufacturing techniques. We will design a small dwelling and export it into a BIM, from which we will extract our data to generate the path the nozzle has to follow. The chosen path is constrained by the material properties, the design and speed of the nozzle. To validate the system we develop a small VR tool in which we mimic a manufacturing tool.

summary	Architects are visual learners. The Internet has enabled interactive learning tools that can be used to assist in visual thinking of structural concepts, especially at the introductory levels. Here, we propose a visual approach for understanding structures through a series of interactive learning modules, or ’gizmos’. These gizmos, are the tools that the student may use to examine one structural concept at a time. Being interactive, they offer many more possibilities beyond what one static problem can show. The approach aims to enhance students’ visual intuition, and hence understanding of structural concepts and the parameters affecting design. This paper will present selected structural gizmos, how they work, and how they can enhance structural education for architects.

summary	Despite recent approaches to enable the mass customization of double curved faÃ§ade panels, there still exist challenges including waste reduction, accuracy, surface continuity, economic feasibility, and workflow disintegration. This paper proposes a computational approach for the design and fabrication of materially informed double curved faÃ§ade panels with complex geometry. This approach proposes an optimized workflow to generate customizable double curved panels with complex geometry and different material properties, and optimize fabrication workflow for waste reduction. This workflow is applied to four different fabrication techniques: (1) vacuum forming, (2) clay extrusion, (3) sectioning, and (4) tessellation. Four experiments are introduced to apply surface rationalization and optimization using Rhino and Grasshopper scripting. Upon simulating each of the four design-to-fabrication techniques through different iterations, the experiment results demonstrated how the proposed workflows produced optimized surfaces with higher levels of accuracy and reduced waste material, customized per type of material and surface complexity.

title	Integrated design in a service marketplace
source	Computer-Aided Design, Vol. 32 (2) (2000) pp. 97-107
summary	This paper presents a service marketplace vision for enterprise-wide integrated design modeling. In this environment, expert participants and product developmentorganizations are empowered to publish their geometric design, CAE, manufacturing, or marketing capabilities as live services that are operable over the Internet. Theseservices are made available through a service marketplace. Product developers, small or large, can subscribe to and flexibly inter-relate these services to embody adistributed product development organization, while simultaneously creating system models that allow the prediction and analysis of integrated product performance. It ishypothesized that product development services will become commodities, much like many component-level products are today. It will be possible to rapidly interchangeequivalent design service providers so that the development of the product and the definition of the product development organization become part of the same process.Computer-aided design tools will evolve to facilitate the publishing of live design services. A research prototype system called DOME is used to illustrate the concept and apilot study with Ford Motor Company is used in a preliminary assessment of the vision.

summary	Generative design methods may involve a complex design space with an overwhelming number of alternatives with their form and design performance data. Existing research addresses this complexity by introducing various techniques for simplification through clustering and dimensionality reduction. In this study, we further analyze the relevant literature on design space simplification and exploration to identify their potentials and gaps. We find that the potentials include: alleviating the choice overload problem, opening up new venues for interrelating design forms and data, creating visual overviews of the design space and introducing ways of creating form-driven queries. Building on that, we present the first prototype of a design analytics dashboard that combines coordinated and interactive visualizations of design forms and performance data along with the result of simplifying the design space through hierarchical clustering.

summary	This paper presents a novel approach for the construction of nonstandard timber structures made from regionally sourced short dimensional lumber, which is enabled through human-robot collaborative assembly (HRCA). To address the research question, three main research objectives are identified and experimentally explored: 1) Characterization of a comprehensive construction process, which consists of off-site HRCA of bespoke timber sub-assemblies, 2) Development of a suitable constructive system for robotic assembly, making feasible the realization of articulated structures out of short timber elements, and 3) Incorporation of these techniques and their constraints into an integrative digital design and fabrication method and implementation of a continuous digital design-to-fabrication workflow.

summary	Several research projects (Gramazio et al. 2014; Willmann et al. 2015; Helm et al. 2017; Adel et al. 2018; Adel Ahmadian 2020) have investigated the use of automated assembly technologies (e.g., industrial robotic arms) for the fabrication of nonstandard timber structures. Building on these projects, we present a novel and transferable process for the robotic fabrication of bespoke timber subassemblies made of off-the-shelf standard timber elements. A nonstandard timber structure (Figure 2), consisting of four bespoke subassemblies: three vertical supports and a Zollinger (Allen 1999) roof structure, acts as the case study for the research and validates the feasibility of the proposed process.

source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This project involves the creation of an architecture of music which may be defined as a series of interdisciplinary steps which seek to generate four-dimensional virtual spaces for the materialization of music. This materialization uses music as its .genetic information ., the virtual space as its medium, and the execution time of the musical piece as the fourth dimension to a three-dimensional virtual space. Within this space, each instrument.s execution is represented by a shape whose properties undergo changes resulting from the musical information. Through the use of new Virtual Reality techniques, we will soon have the possibility to be inside the music, as a habitable place. The achievement of this project is to provide the opportunity to experience this representation through virtual animation.
