summary	This paper describes the procedures developed in the creation of an innovative technique to design and manufacture composite materials with transparency and translucency properties. The long term objective of this research is to develop a method to design and fabricate architectural elements. The immediate objective is to develop the methodology and procedural techniques to design and manufacture a composite material with controlled non homogeneous transparency properties. A secondary objective is to explore different levels of “embedded behavior” or responsiveness by using these techniques to combine different physical material properties on new designed “smarter” and “responsive” composite materials.

title	Hypermedia urban models in virtual environments: Case studies of central areas of Argentine cities
source	International Journal of Architectural Computing vol. 6 - no. 3, pp. 221-241
summary	The virtual models of urban fragments recreate environments of simulation and analysis with a great degree of realism. This paper addresses a review of case studies in which Argentine researchers from three different university centres have worked jointly. We examine spatial databases from a representational and communicational perspective as virtual 3D, walkthrough, and interconnected urban models. Our aim is to explore, recognise and analyse advances in this direction, and to apply them to the development of virtual models of central areas in the Argentine cities of Buenos Aires, Rosario, Santa Fe and Mar del Plata. We present the methodology used to analyse the design, production and management processes of the virtual model as well as the results of our research. We acknowledge that these models are consistent non-traditional instruments of analysis which complement the knowledge of the city and facilitate spatial comprehension. Finally, we review predominant tendencies.

summary	In this research project we explore the defined design and application of digitally fabricated wall panels for room-acoustical architectural interventions. In Particular, we investigate the room-acoustical criteria applying to everyday used spaces. We present a digital design and fabrication process developed to create non-standardised panels and two case studies which apply this process on the acoustical improvement of a specific room situation. Our aim is to find correlations between digitally fabricated surface structures and sound- aesthetical characteristics, in order to utilise these for the architectural design.

title	A collaborative project experience in an architectural framework, working with Open Source applications and physical computing [Diseño de Plataformas Digitales e Interactivas: una experiencia educativa trabajando colaborativamente con aplicaciones de Código Abierto y Computación Física]
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	Nowadays, thanks to the telecommunication revolution and therefore the massive spread of Internet, we have seen the come up of international architectural offices with branches located in different continent, working in a collaborative fashion, surpassing physical and time frontiers. At the same time, the multidisciplinary work between designers, architects, engineers, programmers and even biologist, between others, have been taking place in the new network society. All transformations also supported by the arising of FOSS (Free Open Source Software) and the virtual communities behind them, which allow the creation of non-traditional or specific software, the association between disciplines, and also, the formation of meeting scenarios for a mixture of individuals coming up with multiple motivation to coexist in collaborative environment. Furthermore, it is possible to argue that Open Source applications are also the reflection of a social movement, based on the open creation and exchange of information and knowledge. Do the appeared of FOSS compel us to re-think our working and teaching methods? Do they allow new modes of organizing and collaborating inside our architectural practices?. This paper would like to address these questions, by presenting the results of the “Experience Design” course, which by implementing teaching methods based on Open Source principles and cutting-edge tools, seeks to approach students to these new “way of do”, knowledge and methodologies, and overall, focus them on the science behind the computer. This paper describes the “Experience Design” course, in which architectural graduate students of Universidad Diego Portales (Chile), put for first time their hands on the creation of interactive interfaces. By acquiring basic knowledge of programming and physical computing, students built in a collaborative way a responsive physical installation. The course use as applications “Processing” and “Arduino”. The first one is an Open Source programming language and environment for users who want to program images, animation, and interactions. It has a visual context and serve as a software sketchbook and professional production tool. Processing is a project initiated by Ben Fry and Casey Reas, at the MIT Media Lab (www.processing.org). The second is an Open Source electronics prototyping platform based on flexible, easy-to-use hardware and software. Arduino has a microcontroller (programmed with Processing language) which can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators (www.arduino.cc). Both environments shared a growing community of people working in related projects and extending useful assistance for beginners. In this paper it is presented the current state of the pilot course and some of the initials results collected during the process. Students and teacher’s debates and evaluations of the experience have been exposed. Together with a critical evaluation in relation to the accomplishment of the effort of place together different disciplines in one collaborative project akin, architecture, design, programming and electronic. Finally, futures modifications of the course are discussed, together with consideration to take in account at the moment of bring Open Source and programming culture into the student curriculum.

title	Urban micro-informatics: a test case for high-resolution urban modelling through aggregating public information sources
doi	https://doi.org/10.52842/conf.caadria.2010.327
source	Proceedings of the 15th International Conference on Computer Aided Architectural Design Research in Asia / Hong Kong 7-10 April 2010, pp. 327-336
summary	Our contention is that the city is a rich collection of urban micro-ecologies in continuous formation that include information types outside the traditional boundaries of urban design, city planning, and architecture and their native data fields. This paper discusses working with non-standard urban data types of a highly granular nature, and the analytical possibilities and technical issues associated with their aggregation, through a post professional masters level research studio project run in 2008. Opportunities for novel urban analysis arising from this process are discussed in the context of typical urban planning and analysis systems and locative media practices. This research bought to light specific technical and conceptual issues arising from the combination of processes including sources of data, data collection methods, data formatting, aggregating and visualisation. The range and nature of publicly available information and its value in an urban analysis context is also explored, linking collective information sites such as Pachube, to local environmental analysis and sensor webs. These are discussed in this paper, toward determining the possibilities for novel understandings of the city from a user centric, real-time urban perspective.

source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This work shows the study of the methods and techniques for the development of a virtual vision VRML 3D included in an "Digitally-integrated knowledge base" with interactive interphases of a significantly revitalized fragment of a central area of the city of Rosario, Province of Santa Fé, Argentina, that includes an emblematic heritage for the Argentineans: the National Monument to the Flag. Digital models that partly allow the development of a hypothesis of integration between the digitized information and information technology—new digital proximity— to the effects of being able to investigate the generation of multimedia database that includes three-dimensional and dynamic models of the mentioned type, in this case, urban, architectonic, and cultural heritage. Different views and research on heritage have been developing. Nevertheless, the use of these new 3D non-immersive technologies and inter-phases are opening a new field of vision and understanding of the subject.

summary	ceramiSKIN is the result of an inter-disciplinary investigation between an architect and a ceramics artist. We are exploring natural orders as generators for aperiodic (non-repeating) tiling systems in architectural ceramic cladding systems. Of particular interest are the possibilities offered by digital imaging of organic materials [at various scales from 1:1 to 1:1 nanometer] as a means of form generation. After scanning, shapes are computationally deformed to create a range of biophilic effects promulgated through unique large scale ceramic cladding systems constructed using digital fabrication techniques.

title	Chemical Signaling as a Model for Digital Process in Architecture
doi	https://doi.org/10.52842/conf.acadia.2008.340
source	Silicon + Skin: Biological Processes and Computation, [Proceedings of the 28th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) / ISBN 978-0-9789463-4-0] Minneapolis 16-19 October 2008, 340-345
summary	The role of the architect is quite literally one of assembly: synthesizing the various parts of a project into a cohesive whole. It is a difficult job, often requiring the architect to weave many seemingly contradictory concerns into a solution that benefits them all. It is not surprising then, that the many elegant and effective systems found in nature should be inspiring to the architect. Emerging fields like biomimicry and systems dynamics model the patterns of interaction between organisms and their environments in terms of dynamic part to part and part to whole relationships. ¶ Observations of real relationships between organisms and their environments, as they exist in nature, reveal complex feedback loops working across multiple scales. These feedback loops operate by the simultaneous action of two observed phenomena. The first is the classic phenotypic relationship seen when organisms of the same genetic makeup instantiate differently based upon differences in their environment. This is the relationship that was originally proposed by Charles Darwin in his theory of natural selection of 1859. Darwin’s model is unidirectional: the organism adapts to its environment, but not the other way around. It operates at the local scale as individual parts react to the conditions of the whole. (Canguilhem, 1952). ¶ The second phenomenon, which sees its effect at the global scale, is the individual’s role as consumer and producer in the flows of energy and material that surround it. It is the subtle and incremental influence of the organism upon its environment, the results of which are often invisible until they reach a catastrophic threshold, at which point all organisms in the system feel global changes. ; The research presented in this paper addresses the dialectic between organism and environment as each responds reciprocally to the others’ changing state. Such feedback loops act in a non-linear fashion, across nested scales in biological systems. They can be modeled to act that way in a digital design process as well. This research is an exploration into one such model and its application to architecture: the simple communication between organisms as they affect and are affected by their environments through the use of signal chemicals.

summary	While conventional information displays are still effective, a lack of integration between descriptive and contextual information means they cannot be used independently of additional external information. New digital systems such as Google Maps are increasing in popularity. Unfortunately these present some limitations in terms of understanding both route and survey information, and in particular navigation and orientation, such as intuitively understanding a plan view no matter which way one is facing, so visitors can quickly and intuitively learn how to get to specific buildings or to specific facilities. Digital systems may also alienate older and non computer literate users; and they display contextual information inside an interface which limits the possible range of interaction methods offered by physical interaction. Our solution was to create a 3D physical model that one could spin, which would in turn display digital panoramas that spun in rotational alignment with the physical city model. Further, the user could place category tokens in intersections of the city model, which would bring up digital panoramas on the screen and highlight facilities linked to the category chosen. Rotating the token would also rotate the digital panorama.

title	A survey of computer software for the urban designprocess

summary	Urban design is concerned with the shape, the surface and the physical arrangement of all kinds of urban elements, the basic components that make up the built environment, at the level of buildings, spaces and human activities. It is also concerned with the non-visual aspects of the environment, such as noise, wind and temperature and humidity. The city square is a particular urban element which can take many forms and its geometrical relationships such as maximum dimensions, ratio of width to length and building height to length have been analysed for centuries (Alberti 1475), (Vitruvius 1550), (Sitte 1889), (Corbett 2004). Within the current urban design process there are increasing examples of three dimensional computer representations which allow the user to experience a visual sense of the geometry of city squares in an urban landscape. Computer-aided design and Virtual Reality technologies have recently contributed to this visual assessment, but there have been limited attempts at 3D computer representations which allow the user to experience a greater sense of the urban space. This paper will describe a survey of computer tools which could support a more holistic approach to urban design and which could be used to simulate a number of urban texture and urban quality aspects. It will provide a systematic overview of currently available software that could support the simulation of building density, height, colour and style as well as conditions relating to noise, shading, heat, natural and artificial light. It will describe a methodology for the selection and filtering of appropriate computer applications and offer an initial evaluation of these tools for the analysis and representation of the three-dimensional geometry, urban texture and urban quality of city centre spaces. The paper is structured to include an introduction to the design criteria relating to city centre spaces which underpins this research. Next the systematic review of computer software will be described, and selected tools will undergo initial evaluation. Finally conclusions will be drawn and areas for future research identified.

summary	Sense-of-the-City was a project that was executed in the city centre of Eindhoven using mobile phones with GPS. Ten persons carried this equipment during the working day for a period of one week. While carrying their route was traced and projected on a map that could be viewed on the internet. The citizens were asked to pictures of places of interest. These pictures are uploaded to the server and attached to the route. Later on text can be added to each picture through the website. All participants showed a high level of engagement in the project. Although the logbooks of the routes that were created on the web provided very personal insights, it was very hard to draw conclusions from these data.

summary	As technology advances, users get more detached from the way things work and are produced. Users end up being pure consumers and leave their positions as decision makers behind. Before the architecture and buildings processes were industrialized, most practitioners of the so-called vernacular architecture were in fact the dwellers of what they built and they easily met the specific personal needs since they were in total control. Some “architectural theorists have turned to vernacular construction with the conviction that such buildings and settlements express the interconnectedness between humans and the landscapes they live in.” (Beesley and Bonnemaison 2008). Considering the present day intense building activity, such relationship of dweller and architecture seems not possible excepting a very few examples to later referred to. This paper will instead focus on the possibility of the non-architect users of architectures as decision makers in order to reach designs that meet the requirements of their addressees.

title	A simulation model development of firefightingactivity by community residents against coseismic firespread using multi-agent systemAs a support tool for community-based disaster preventionplanning

summary	This paper attempted to develop a simulation model of residents’ firefighting activity against coseismic fire spread using multi-agent system. The developed model was applied to a case study area. In the application, the simulations were carried out to the existing area and eleven cases of the assumption (virtual conditions) of the area where are implemented various non-physical and physical measures. As a result, the measures with only physical and haphazard multitude of measures did not show a remarked effect of disaster prevention performance. And, it is confirmed that the model can visually, dynamically and quantitatively output results. From these outputs, the possibility of contribution for enhancing residents’ awareness and drafting a plan of disaster prevention was confirmed. However, there are still some problems to be solved for the practical use of the model.

title	Networked mobilities and new sites of mediated interaction
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 279-286
summary	This paper takes point of departure in an understanding of mobility as an important cultural dimension to contemporary life. The movement of objects, signs, and people constitutes material sites of networked relationships. However, as an increasing number of mobility practices are making up our everyday life experiences the movement is much more than a travel from point A to point B. The mobile experiences of the contemporary society are practices that are meaningful and normatively embedded. That is to say, mobility is seen as a cultural phenomenon shaping notions of self and other as well as the relationship to sites and places. Furthermore, an increasing number of such mobile practices are mediated by technologies of tangible and less tangible sorts. The claim in this paper is, that by reflecting upon the meaning of mobility in new mediated interaction spaces we come to test and challenge these established dichotomies as less fruitful ways of thinking. The paper concludes with a research agenda for unfolding a ‘politics of visibility’, engaging with the ambivalences of networked mobilities and mediated projects, and critically challenge of taken for granted interpretations of networked mobilities.

title	Construction of a design support system for the public space design in which a citizen participates: The interactive design system in a workshop
doi	https://doi.org/10.52842/conf.caadria.2008.426
source	CAADRIA 2008 [Proceedings of the 13th International Conference on Computer Aided Architectural Design Research in Asia] Chiang Mai (Thailand) 9-12 April 2008, pp. 426-432
summary	Workshops are held with local residents’ participation as one technique by which residents plan roads and places along a route. Because residents without special knowledge participate in such workshops, it is necessary to show the contents intelligibly so that all participants might grasp the plan contents and examine them. Moreover, for community planning workshops, because the time during which they can be held is restricted, within that time, plan- related information must be organized efficiently for rapid examination and searching of its contents. As an interactive system, a real-time simulation (RS) is sought that allows rapid drawing and that has a structure to display the contents of a plan using a three-dimensional space model in real time. The purpose of this research is to build a system that supports environmental space design, which uses RS in the workshop, and which is applicable for evaluation of an actual street space maintenance plan.

title	The Impact of Information Technology on Architectural Education in the 21st Century
source	First International Conference on Critical Digital: What Matters(s)? - 18-19 April 2008, Harvard University Graduate School of Design, Cambridge (USA), pp. 3-6
summary	Architecture is a technology-intensive discipline. It uses technology—both in the process of designing and in its products—to achieve certain functional, cultural, social, economic, and other goals. In turn, technology transforms the discipline. The importance of technology to the discipline and to the practice of architecture has been demonstrated again and again throughout history. In the 21st century, the advent of computer-aided design, computerassisted collaboration, construction automation, “intelligent” buildings, and “virtual” places, promise to have as much of an impact on architectural design processes and products as earlier technological advances have had. Like most other early adoptions of a technology, the first uses of computing in the service of architecture mimicked older methods: electronic drafting, modeling, and rendering. But this rather timid introduction is changing rapidly: new design and evaluation tools allow architects to imagine new building forms, more responsive (and environmentally more responsible) buildings, even radically new types of environments that blend physical with virtual space. Communication and collaboration tools allow architects, engineers, contractors, clients, and others to work much more closely than was possible before, resulting in more complex, more innovative, and more effective designs. Understanding and shaping this transformation are the basis of architectural education in the 21st century.

title	Study of Architectural Shape Formation in Comparison with Natural Morphogenesis Using Computer Simulation
source	Proceedings of the 8th European Architectural Endoscopy Association Conference
summary	Geometric accuracy of architectural computer models allows to percept and to analyze the three-dimensional spatial compositions using computer images. The concepts and methodology of modern interdisciplinary science, in particular fractal geometry, have already been successfully applied in the various scientific fields, as astronomy, physics, chemistry, biology. Modern ecological paradigm does not separate human life and anthropogenic world from the natural environment considering all as unitary nonlinear ecosystem. The analysis of the architectural shape formation is a part of the study of morphogenesis in such different worlds, as non-living and living nature and man-made forms – real as well as virtual architecture.

summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.
