title	Innovative Expert Systems With Hypertextual User Interfaces: A Special Support for the Building Recovering Project
source	Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary	In this paper, first of all a short account on the peculiarity of knowledge in the domain of Architectural and Building Project, particularly in the Building Recovering Project is given. Thatmeans to focus the concept of "degree of authority" of different types of knowledge with regard to project: regulations; specialist literature having in practice the value of self-regulation; technical updating; exemplary design cases; warnings; analysis methods; heuristics; orientating references. Consequently, the different roles of two basic design & decision support systems, that is expert systems and hypertexts, are considered. The former seem to be quite fit for representing information and knowledge linked to a clear "authority", the one of experts in a certain domain; the latter seem to be quite fit for illustrating the interdisciplinary complexity, different historicinterpretations, various analogous references, and so on. Afterwards, the limits of expert systems based on the logic "true-false" are underlined, and the perspective of expert systems based on more sophisticated and appropriate rules and metarules is proposed. At last, the possible structure of such an innovative expert system, with a hypertextual interface, in the domain of Building Recovering Project is exemplified.

title	Some Notes on the Incompleteness Theorem and Shape Grammars
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 368-376.
summary	The paper presents a critique of the Shape Grammar paradigm viewed through the lens of the incompleteness theorem of Gödel. Shape Grammars have been extensively researched through many lenses. Their productive systemic nature was the focus of the first papers along with more recent treatises in the field while their use in analysis of known building styles has been extensive and a proven mechanism for style analysis. It is surprising though that use of Shape Grammars in actual design in practice however has been minimal. The architectural community has not actively used the paradigm in the design of real buildings, probably because of the rigid analytical approach to style and rules, following from the academic analysis that the paradigm has been subjected to. However I propose that there is another underlying reason, other than the rigid approach to construct a Shape Grammar. The nature of the concurrent application and creation of the rules lies close to the incompleteness theorem of Gödel, that uses a multitude of Turing Machines to prove that a from a set of True Axioms -A- we will never be able to determine if all sentences are true, without having to invent new axioms, outside the initial set -A-, thus unproven in terms of their true or false nature. Negation of this possibility drives us to the conclusion that true Design can never be feature -complete and thus can never be placed in a trusted framework that we all agree or believe it to be the complete truth.

title	Convoluted City: The latent space as tangible matter
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 1: Projects Catalog of the 43rd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-8-1]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 82-91.
summary	As chimeras of the city and its entangled natural environments are distributed across the planet, Convoluted City opens up a space where new notions of the built environment can begin to emerge. True- and false-color remote sensing images were curated and processed with neural networks, and we demonstrated that by converting generative adversarial network (GAN)-generated images into dithered material deposition descriptions, two-dimensional image data can be converted into physical, materially heterogeneous objects (Figures 1 and 2). The models were exhibited at the Resilienze Festival in Bologna, Italy, in June 2023.

title	Pseudoperspectivas / Realización de un Fotomontaje Diédrico [Pseudoperspectives / Making a Dihedral Photomontage]
source	SiGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay - Montevideo 12 - 14 November 2014, pp. 285-289
summary	As the term suggests, a pseudoperspective involves performing a false perspective, and is the result of combining two different projective systems: Diedric Orthogonal System with the Central perspective System. Despite its heterodox character, this nifty graphic resource is used since the invention of perspective. With the digital graphics development of pseudo-perspectives currently allows new expressive possibilities. In this paper an academic exercise conducted with students from a curriculum during the first year of a career in architecture is presented. This work consisted of performing a photomontage from an elevation or vertical section.

title	Geometry, Light, and Cosmology in the Church of Hagia Sophia
source	International Journal of Architectural Computing vol. 5 - no. 2, pp. 304-319
summary	Designed by a physicist and a mathematician, the Hagia Sophia church in Istanbul, Turkey acted as an experimental test case in which advanced knowledge of geometrical constructs, sophisticated understanding of light behavior, and religious and cosmological beliefs combined to create a magnificent structure. While some of its design concepts are known, many remain hidden. Earthquakes have demolished parts of the church—such as the original dome. Researchers have in the past misinterpreted their observations and perpetuated false conclusions. Lastly, the lack of digital tools has until now prevented verification and analysis of prior findings. In this paper, we integrate traditional historical research, parametric digital analysis, and lighting simulation to analyze several aspects of the church. In particular, we focus on the geometry of the floor plan, the geometry of the apse, and light behavior in the original dome. Our findings point to the potential of digital tools in the discovery of a structure's hidden features and design rules.

title	Not Just Another Pretty Face: Images and Arguments in an Anthropology Web Site
source	CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 635-654
summary	We are developing a web site with photorealistic animations and virtual reality walk throughs of architecture and artifacts at an archaeological site in El Salvador. The goal of the site is to support research and teaching about household anthropology in sixthcentury Meso-America. To counter the false sense of realism and truth these experiences often convey we have developed Image Arguments, a scheme for integrating with images the arguments and data that they are based on. We provide this contextual information using a server side database and client side Java applets, enabling viewers to examine the assumptions and the data behind the images.

title	Simulating Dynamic Forces in Design with Special Effects Tools
doi	https://doi.org/10.52842/conf.ecaade.2007.219
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 219-226
summary	Special effects technology can facilitate dynamic sketching in the early stage of a design project without needing time-consuming effort. This form of sketching was tested in a design studio taught by the author. The study of dynamic materials and oceanfront site conditions set the stage at the beginning of a design process for a more comprehensive analysis later on. On the one hand, the risk of using special effects tools is that the visual look can seem convincing, but the apparent result is based upon an overly simplified set of assumptions. On the other hand, the use of such technology can be very stimulating to the design imagination without requiring complex analysis that may bog down the free flow of ideas. Once a greater commitment is made to a particular design proposal, more complete physical analysis and modeling can be undertaken to help avoid the risk of false first impressions. In the studio, cloth simulation was used to develop the design of tension membrane structures (tents) that retracted and unfurled in a series of complex movements. Fluid dynamics effects were used in the design and development of related boat dock facilities. A wind-tunnel simulation tool was used to explore the performance of the tension-membrane fabrics under varied wind loads. The visualization techniques were complemented by ¼ to ½ scale assembled components created by rapid prototyping. The use of an actual wind-tunnel further tested the prototypes in some cases. On the whole, quickly implemented special effects were the starting point for reacting to and developing some initial design concepts and served as the basis for more complete physical modeling of prototypes later on. Using animation as a design method is well established in other work (Hirschberg 06). Animation is also a helpful way to work out the step by step assembly of complex architectural form (Mark 95). The special effects tools permit a larger range of initial design alternatives to be initially considered that are subsequently narrowed down by physically based prototypes that are more predictive of real world performance.

title	A Web-based Virtual Lighting Simulator
doi	https://doi.org/10.52842/conf.acadia.2002.269
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 269-277
summary	This paper is about a web-based “virtual lighting simulator” that is intended to allow architects andlighting designers to quickly assess the effect of key parameters on the daylighting and lightingperformance in various space types. The virtual lighting simulator consists of a web-based interfacethat allows navigation through a large database of images and data, which were generated throughparametric lighting simulations. In its current form, the virtual lighting simulator has two main modules,one for daylighting and one for electric lighting.The daylighting module includes images and data for a small office space, varying most key daylightingparameters such as window size and orientation, glazing type, surface reflectance, sky conditions, andtime of the year. The electric lighting module includes images and data for five space types (classroom,small office, large open office, warehouse and small retail), varying key lighting parameters such as theelectric lighting system, surface reflectance, and dimming/switching.The computed images include perspectives and plans and are displayed in various formats to supportqualitative as well as quantitative assessment. The quantitative information is in the form of iso-contourlines superimposed on the images, as well as false color images and statistical information on workplane illuminance. The qualitative information includes images that are adjusted to account for thesensitivity and adaptation of the human eye. The paper also contains a section on the major technicalissues and their resolution.

summary	In this paper, we explore conditional generative adversarial networks (cGANs) as a new way of bridging the gap between design and analysis in contemporary architectural practice. By substituting analytical finite element analysis (FEA) modeling with cGAN predictions during the iterative design phase, we develop novel workflows that support iterative computational design and digital fabrication processes in new ways. This paper reports two case studies of increasing complexity that utilize cGANs for structural analysis. Central to both experiments is the representation of information within the data set the cGAN is trained on. We contribute a prototypical representational technique to encode multiple layers of geometric and performative description into false color images, which we then use to train a Pix2Pix neural network architecture on entirely digital generated data sets as a proxy for the performance of physically fabricated elements. The paper describes the representational workflow and reports the process and results of training and their integration into the design experiments. Last, we identify potentials and limits of this approach within the design processes.

title	Anamorphic Perspective & Illusory Architecture
source	International Conference on Generative Art
summary	Anamorphic perspective can be sometimes quite paradoxical. This is the case with the famous false vault by Andrea Pozzo at Saint Ignatius in Rome. Pozzo himself did not consider this painting as an anamorphic projection, but it is indeed. Pozzo deduced the correct perspective drawing for the large canvas (intelaiautura), but what the observer sees is quite different. This article is divided into three parts that can be read separately depending upon the reader’s inúterest. The first part gives us an historical review through some treatises related to the subject and some famous masterpieces. The second part deals with the principles that govern anamorphic perspective, considering the basic cases of projection. One of these cases is preúsented in detail in this part. Finally, the third part is devoted to the analysis of the vaults of Sant’Ignazio and Collegio Romano by means of the author’s method, termed Modular Perúspective. For a better understanding of the origin of Saint Ignatius’s vault, we include a brief historical background in order to grasp the idea that Pozzo’s painting is fundamentally an architectural solution instead of a purely pictorial exercise.

title	Hand-Machine Conflict and the Ethics of Digital Fabrication
source	Cheng R and Tripeny PJ (eds) Getting Real: Design Ethos Now, Proceedings of the 94th Annual Meeting of the Association of Collegiate Schools of Architecture, Salt Lake City, 2006, 207-214
summary	The introduction of machines into human affairs produces tension between competing needs. We need to engage the world directly with the hand, and we need to augment the hand with mechanical power. What is the right balance between human autonomy and mechanical influence – between direct and indirect control? With the rise of the computer age, we seem to resolve the matter in favor of machines, encouraging their unrestrained expansion. However, a Resistance Movement persists. It resurfaces with each wave of technological invention, rekindling the tension. This can be seen in the current debate over the appropriate use of digital fabrication technology. Some architects believe it yields unprecedented creative freedom by overcoming the restrictions of mass production. Others believe it alienates us from a vital source of inspiration by deemphasizing direct contact with material. This paper examines the hand-machine conflict in its current form, and argues that its polarized categories cloud our thinking with false moral alternatives such as: embrace technology and foster a new aesthetic age, or resist it and protect mankind from further alienation. Instead, we should seek a third alternative that frees us from this either-or thinking. One established way of doing this in architectural design is to use traditional media and computer media in oscillation. The paper critically evaluates this approach and presents a design studio experiment that moves beyond oscillation, seeking a higher degree of hand-machine unity.
