title	Uso de Patrones de diseño aplicados a grafos espaciales en redes de ingeniería y arquitectura [Use of Design Patterns Applied to Space Graphs in Networks of Ingeneering and Architecture]
source	2da Conferencia Venezolana sobre Aplicación de Computadores en Arquitectura, Maracaibo (Venezuela) december 2001, pp. 116-125
summary	This article describes a design pattern, based on the concept of Spatial Graph that facilitates the development of systems of information (SIG) oriented to objects. The patternís purpose is to provide a solution reusable to the problem of the representation, manipulation and visualization of nets of services in conventional SIG. The reuses of the pattern allows that in a net of services each node or connection is defined as a space object, this adds realism to the manipulation and visualization of the same one. The pattern simplifies the design of applications providing structures of design reusable in a great variety of domains.

summary	The bar in the Architectural Association, named after the bust that sat in one corner, had white formica topped tables. Each day around lunchtime these were cleaned with Vim by the bar staff, ready for the new day’s thought’s, ideas, and occasional inspirations. Students used the bar as an ideal place to discuss their work, the table tops providing an endless supply of virtual napkins waiting not to be used but to be drawn on. This atmosphere of providing a relaxed environment to discuss and debate architectural ideas proved immensly popular, with tea spills adding to the table top sketches. It is often forgotten in the ordered cleanliness of the CAD studio, where the protection of the computers overrides the comfort of their users, that ideas and their development do not always come when we most expect. Providing an atmosphere in which the designer feels comfortable enough to play is as vital now as at the time when the Architectural Association was seen as an ideal place to foster debate. As the architect feels more comfortable, so will the ideas flow more freely. This paper demonstrates how a CAD environment can become the virtual equivalent of a coffee bar as it relates to the design studio, where ideas are thrown around with abandon, and where the discussion of those ideas is more important than the material with which the ideas are depicted. In contrast, the use of computers in design is following along the same path as beautifully descriptive artwork or highly skillful technical drawings, that say much about the presentation abilities of their authors, yet often little about the actual designs. Designers often are so seduced by the medium that they do not properly see the message. A computer’s ability to present three dimesnional form instantly, and the ease with which those forms may be altered, stretched, shrunk, reversed and so on make the computer an ideal sketching tool. This paper shows the results of the combined RIBA Part II and MSc Computing and Design course. This two year, 96 week course is entirely computer based, and uses generative modelling to explore the fundamental nature of the design of form. This paper seeks to show how this approach may be successfully used with some students, and how the approach complements existing teaching methods and techniques. To accompany these notes a computer based presentation will illustrate a variety of past and present student work. This will show how rule based form, and the use of computers as a sketching tool, has influenced the students' working methods and their approach to the creation of form. Finally, we will show that the use of such a formal approach leads inevitably to a greater understanding of, and therefore a greater ability to articulate and illustrate, a student’s own design ideas and proposals. The use of the computer at every stage of the design process forces the student to be entirely explicit about every action as it occurs. Similarly the rule based approach requires them to be explicit about actions they propose to take in the future. This double combination has produced students who are highly articulate about their designs at every stage, and this paper aims to demonstrate that the more articulate the student, the greater is the possibility for success.

title	Integration of Space Syntax into Agent-Based Pedestrian Simulation in Urban Open Space
source	P. Janssen, P. Loh, A. Raonic, M. A. Schnabel (eds.), Protocols, Flows, and Glitches - Proceedings of the 22nd CAADRIA Conference, Xi'an Jiaotong-Liverpool University, Suzhou, China, 5-8 April 2017, pp. 325-334

summary	MAS can be utilized to analyse macro rules of whole system by simulating a number of active agents. However, simply based on the parameter of specific environment quality and incomplete statistical setting of individual, models of pedestrian traffic in realistic open space have often been imperfect, because the behaviour of people cannot be rationally reflected to the complex characteristic of space. Space Syntax Theory breaks down the space into components and measures each with the straight sight-line of individuals, which can help analyse and quantify pedestrian flow in complicated real-life environment. In this situation, we make an attempt to combine these two in our research, in order to simulate the moving of pedestrian closer to reality. In this paper, Gulou Square, an urban open space close to centre of the city with a large flow of people, is selected as the study site. The results after plenty of simulations and contrast tests can be concluded that with the assistance of Space Syntax Theory, MAS can be more functional solving the problems in sophisticated real-life environment.

summary	We propose and describe a working computer implementation for shape grammars that handles embedding relations in two dimensional shapes. The technical framework proposed explores a graph data structure to temporarily represent boundary elements of shapes and how they are assembled. With the associated algorithms, this structure enables a systematic search for parts. The employment of user defined constraints allows for an interactive search. In accordance with the continuous character of shapes, the study puts forth a practical part detection method, which extends to non-deterministic cases.

summary	This paper introduces a method to obtain quantified style description vector which is for computer analysis input by using image style classification task. In the experiment, 3331 architectural photos of three styles obtained by crawling and filtering were used as training data. A deep convolutional neural network was trained to map architectural images to high-dimensional feature space, and then the high-dimensional style description vector was used to output the measurement results of style cognition with fully connected neural network. Tested by test data-set of 371 architectural pictures, the accuracy rate of style cognition reached more than 80%. The neural network using architectural data training was applied to the style cognition of non-architectural objects, high accuracy rate was also achieved, it proved that this quantified style description vector did include the information about style cognition to some extent instead of simply classification. Finally, the similarities and differences between the cognitive characteristics of style of neural network and human beings are investigated.

title	Gelassenheit: Dilemma of Computational Thinking in Architecture

doi	https://doi.org/10.52842/conf.ecaade.2007.275
summary	Computational design technologies and tools though operate on a very high level of decisiveness and precision, have a common goal to provide further possibilities of setting free. The terms of rule-based systems, algorithmic thinking processes, parametric design data-bases though drag us to a distant place deep-in digital environment, are all there for a better dwelling on earth and a better understanding of world. How architects relate themselves to their environment of design and realization is a problem of how they relate themselves to the world in the larger frame. Representational thinking initiated by modern science and technology which bases itself on the object quality of being by “enframing” things through their measurable aspects, causes modern age to be an age of “pictures”; where the touch with being is “in oblivion”. Martin Heidegger’s concept of gelassenheit (letting-be, releasement and calmness) reminds the essential nature of thinking as not moving towards and forward with a will-to-power but by stepping back to offer the required offenheit (openness) to the coming-into-being of anything that is with a will-not-to-will. It is about being-in-the-world and dwelling on earth as a part of it. According to this paper, for a further understanding of architectural thinking, space, and production, and the changing paradigms of architecture in the computational era, Heidegger’s concept of gelassenheit both provides a basis and surprisingly encounters us as a recent and future architectural condition.

summary	Computational design technologies are providing the conditions to advance the ways of design thinking and making. Though there are diverse approaches in the current architectural ideations and applications, the images produced by these technologies grab the most attention. These images mostly show off how different architecture can be by the use of computation. This paper will be criticizing this existing condition by discussing the change in the concept of “reality” with the advance of digital technologies, and its effects on our understanding of architectural materiality. So besides being a critique on current ‘picture’ of architecture, this paper aims at dragging attention to the implicit potential of the current computational technologies in a different perspective.

title	Variable Voxel Computing Method - Innovative Approaches to Reduce the Computing Load in Voxel-based Solid Modeling and New Representation Methods
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. 663-671

summary	The concept of "voxel" refers to a volumetric element or volumetric pixel and corresponds to the smallest piece that can be computed in solid and complex model analysis. The voxel-based solid modeling commonly used by geometry-based CAD (Computer-Aided Design) applications. Whilst other geometry-based modeling methods, it uses pixels as the smallest unit instead of dots or vectors. However, the size of the data contained in the smallest unit causes problems such as computing load and representation inaccuracies. This study fundamentally aims to find a fast and effective method for voxel-based solid modeling. While doing that it presents a new visualization algorithm. During the research, the transformation of a geometric model into voxels, then the reproduction of these voxels, and finally, the representation method were practiced and compared. In this process, three complex models were developed and compared by their complexity, their voxelization time, and the amount of time that spend during the formation. As a result, the study proposes new representation methods for voxel-based solid modeling.

summary	A visibility algorithm has been developed and practiced on the iconic towers of Istanbul from various locations with multiple observation points. This research accepts visibility as a binary subject and limited subjective perspectives. Using visibility as a design strategy is a prevalent technique for designers. Applying visibility aspects to the design is an outcome of psychological research in the 60s. Benedikt was the first person who added visibility to his architectural studies. Visibility refers to being able to see or be seen from a distance. This research accepts and practices this definition on two iconic towers of the city of Istanbul with the model MoV (Model of Visibility) developed. The implantation of the developed model is represented with the voxel modeling method. To be able to provide volumetric data, voxel-based representation was explicitly applied to the digital models of iconic towers. This representation model aimed to illustrate and quantify the visible and non-visible areas according to the location of the observation point’s visibility range.

summary	This work presents the development of an applied research related to the installation of rainwater drainage systems in areas of economic and social vulnerability in São Paulo City, Brazil. It is also relevant for us to encourage participatory processes that involve the local community in problem-solving activities, while allowing appropriation of the technology applied. In this case, we are employing light prefabrication based on high performance microconcrete, molded in formwork produced with the aid of digital manufacturing. Our main purpose is to promote urban improvements in precarious settlements along with local economic development, made possible by self-management and community production.

Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 546-555.
doi	https://doi.org/10.52842/conf.acadia.2020.1.546
summary	Active-Casting explores the use of bespoke computer numerical controlled (CNC) manufactured knits to produce volumetric textile formwork for casting glass-fiber-reinforced concrete (GFRC). As a collaboration between experts in architecture, textile fabrication, and civil engineering, the research investigates multimaterial, functionally graded knit formwork as a fully seamless system to cast concrete. Working with controlled characteristics such as elasticity and stiffness of yarn type and knit structure, the soft textile is conceived as the vessel that defines the performative characteristics of volume, geometry, and surface detail. With only a minimal frame to suspend the volumetric cast, hydrostatic pressure “inflates” the fabric formwork, creating a dynamic form-finding process that eliminates the need for typical molding materials such as wood or foam. While active formfinding processes for CNC knit casting have been explored as an open-face, GFRC-sprayed system, the Active-Casting process produces a finished surface on all faces, embedded with expressions in form and surface detail from the knitted formwork. The precast units using this process reduce the amount of construction waste for formwork production, proposes a more automated fashion for manufacturing the formwork, and produces casts with complex geometries difficult to accomplish with traditional casting methods.

title	Simulating Human Behaviour in Built Environments
source	Computer Aided Architectural Design Futures 2005 [Proceedings of the 11th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-3460-1] Vienna (Austria) 20–22 June 2005, pp. 301-310
summary	This paper addresses the problem of predicting and evaluating the impacts of the built environment on its human inhabitants. It presents a simulation system comprising a usability-based building model and an agent-based virtual user model. The building model represents both geometric information and usability properties of design elements, and is generated automatically from a standard CAD model. Virtual users are modelled as autonomous agents that emulate the appearance, perception, social traits and physical behaviour of real users (walking, sitting, meeting other virtual users, etc.). Their behaviour model is based upon theoretical and practical environment-behaviour studies, real world data from a field study, and Artificial Life research. By inserting the virtual users in the usability-enabled building model, and letting them “explore” it on their own volition, the system reveals the interrelationship between the environment and its users. The environment can then be modified, to see how different arrangements affect user behaviours.

title	Beyond Embodiment - An Existential Project of Digital Tectonics in the Posthumanist Discourses
source	A. Globa, J. van Ameijde, A. Fingrut, N. Kim, T.T.S. Lo (eds.), PROJECTIONS - Proceedings of the 26th CAADRIA Conference - Volume 2, The Chinese University of Hong Kong and Online, Hong Kong, 29 March - 1 April 2021, pp. 91-100
doi	https://doi.org/10.52842/conf.caadria.2021.2.091
summary	The paper is a theoretical review on the nature of tectonic expressions in the context of digital design and construction. By investigating the origin of digital tectonics as a methodological exploration to dissolve the oppositional relationship between the digital and the tectonic, the paper identifies the lack of focus on the essential task of tectonic expression-constructing embodied experience on the building form. Therefore, the paper firstly reviews how tectonic expression is understood in its traditional sense, particularly within its indispensable relationship to human body in order to construct the empathic perception of structural dynamics. Then, the paper reveals the disassociation between human body and tectonic form in the posthumanist mode of design-to-construction of the digital age. Further, by articulating the dynamic nature of embodiment in the posthumanist scenario where the body is constantly reconstructed by the technocultural conext of the living environment, the paper proposes a theoretical model arguing for a reinterpretation of both the nature and the task of digital tectonics in order to reclaim the embodied experience in the digital age. Digital tectonics becomes an existential project that must be designed within its mutual determining relationship with the historical-cultural construction of the body-self.

summary	This article explores the intersection of architectural forms and human behaviour through a video-tracking analysis method. Focusing on the impact of geometrical subdivision of public zones on social behaviour, it addresses limitations of current video-tracking tools. By introducing the customized BodyCAM software, architects can interactively delineate zoning boundaries on video footage, enabling detailed analysis of spatiotemporal patterns. The software tracks pedestrians, identifies geometric boundaries, and correlates behaviour patterns with spatial configurations, offering a novel approach to understanding human behaviour in complex architectural environments. This synthesis enhances both conceptual and operational aspects of architectural design in association with environmental behaviour, emphasizing the intricate interplay between architecture and the human body.

summary	From the invention of projection to the emergence of digital technology, there's a clear correspondences among the transformations of visual representation paradigm in art, the developments of design instrument in architecture, and the human perception of time/space. Base on the examination of this particular historical trajectory, this paper focuses the working mechanism of shifting perspective as an alternative design instrument to explore the possibility of embedding time and motion into static form in digital age. Firstly, the paper reviews how the shifting perspective was introduced to represent space in modern western painting and photography. Then based on the research on shifting perspective, the paper develops a design tool, which would be able to translate motion into the particular geometrical feature of a generated 3D object. In the end, the paper brings further discussions about the formal and spatial effects brought by this new tool, and its potential to incorporate the perceptive image of human being into design process.

doi	https://doi.org/10.52842/conf.caadria.2018.1.091
summary	The "digital turn" in architecture is ontologically drawn from Deleuzian philosophy, particularly the thinking defined by Manuel Delanda as real virtuality. This philosophical thinking reflects the essential paradigm of digital design-a generative process driven by intensive difference to approach the singularity of form in a space of possibilities. However, no matter how dynamic the design process is in digital software, the construction result of a building is unavoidably static and permanent. Thus, the essence of digital design will always be misaligned with the material reality of its production. Addressing on this confliction, the research is trying to rethink the philosophical term "real virtuality" in the process of human perception. By examining different theories about the anti-static condition of perception, it forms a novel perspective to address the dynamic relationship between building form, virtual "information" and human perception, and extends the productivity of "becoming" from digital design process to the process of building colonization.

summary	As a traditional design media, drawing usually has limitations in dealing with non-Euclidean geometrical problem, and therefore is highly challenged by the digital tools in contemporary architecture. This paper offers an explanation of the working mechanism of spherical perspective, an alternative projection instrument, to explore the potential of drawing in digital design scenario. Firstly, the paper reviews how architects notated nonorthogonal geometry by introducing perspective projection into the drawing system of Stereotomy in history. Then based on the conclusion from historical research, the paper develops a design tool, which would be able to translate geometry from orthogonal projection system to spherical one to generate non-Euclidean form. In the end, the paper brings further discussions about the formal and spatial effects brought by this new tool, and its potential and difficulty to be developed into professional design and representation media for architectural practice.

A new and viable remeshing algorithm is proposed that a free-form surface could be converted into a certain mesh grid, in which the edges represent the weaving elements, and the vertices represent their joints. The research essentially seeks to integrate the intangible cultural heritage into the construction technique, as well as to narrow the gap between the com- plex geometry with digital fabrication.

summary	This paper reports the development of VBFRED-IVY, a computational tool that is used to model and analyze the thermal effects of plants on buildings under Singapore climatic conditions. In VBFRED-IVY, the vegetation-air temperature and surface temperature of a planted wall and a non-planted wall are investigated respectively. Climatic data of Singapore are input to do the parametric testing. Then field measurements are carried on three planted walls in different orientations, and statistics method is applied to evaluate the simulation program. The results show that VBFRED-IVY is efficient.
