summary	By investigating methods for using computation and digital manufacturing technologies to integrate material properties with architectural design tools, the research in this paper aims at revealing new potentials for the use of wood in architecture. Through an explorative approach, material particularities and fabrication methods are explored and combined into new workflows and architectural expressions. The research looks into different properties and capacities of wood, but the main part of the experimentation revolves around crooked oak logs. Due to their irregularities, these logs are normally discarded. However, through the methods suggested in this research, they are instead matched with unique processing informed by their divergence. The research presents a workflow for handling the discrete shapes of sawlogs in a system that both involve the collecting of material, scanning/digitization, handling of a stockpile, computer analysis, design, and robotic manufacturing. The workflow includes multiple custom-made solutions for handling the complex and different shapes and data of wood logs in a highly digitized machining and fabrication environment. The suggested method is established through investigations of wood as a natural material, studies of the production lines in the current wood industry, and experimentation in our in-house laboratory facilities. This up-cycling of discarded wood supply establishes a non-standard workflow that utilizes non-standard material stock and leads to a critical articulation of today’s linear material economy. The research thereby gives an example of how the natural forms and properties of sawlogs can be directly used to generate new structures and spatial conditions.

title	Urban Identity Through Quantifiable Spatial Attributes: Coherence and dispersion of local identity through the automated comparative analysis of building block plans
source	Design Computation Cognition conference 2008
summary	This analysis investigates whether and to what degree quantifiable spatial attributes, as expressed in plan representations, can capture elements related to the experience of spatial identity. By combining different methods of shape and spatial analysis it attempts to quantify spatial attributes, predominantly derived from plans, in order to illustrate patterns of interrelations between spaces through an objective automated process. The study focuses on the scale of the urban block as the basic modular unit for the formation of urban configurations and the issue of spatial identity is perceived through consistency and differentiation within and amongst urban neighbourhoods.

title	Automatic production of paths within audiovisual “narrative space” by making use of genetic algorithms
doi	https://doi.org/10.52842/conf.ecaade.2006.458
source	Communicating Space(s) [24th eCAADe Conference Proceedings / ISBN 0-9541183-5-9] Volos (Greece) 6-9 September 2006, pp. 458-461
summary	This paper documents the theoretical aspect of a research project that deals with the application of an artificial life (AL) approach to engraving coherent paths within the narrative space of video fragments. These paths, which are constituted by the succession of short video segments, represent the best way to juxtapose isolated elements in the overall narrative landscape. In this case the notion of space is being used in a metaphorical way. Once this has been clarified, the concept of “narrative space” is used as a metaphorical representation of a database comprising all the fragmented/autonomous narrations that are being used. Therefore, the creation of an “intelligent” system that will be able to automatically create cinematographic narration is being examined. This project in particular investigates the possibility and the consequences of producing an autonomous cinematographic narration system, in which meaning results from a kind of hypermontage (Hakola, http://www.kromaproductions.net/HYPERMONTAGE.htm: Jan 2003) conditioned by genetic algorithms. A different type of spatial experience emerges when the video fragments used are automatically “put together” by the system. Video as a medium could be considered as representing crystallized shortcuts within physical reality. Since video fragments constitute the database, different elements of constructed space are parts of the same ensemble. From the composition of such fragments, there emerge new paths within the same spatial context and certain spatial experiences are formulated which are different from the ones experienced by actors during the shootings.

title	Contemporary Metropolitan Conditions: New challenges for design education
doi	https://doi.org/10.52842/conf.ecaade.2010.157
source	FUTURE CITIES [28th eCAADe Conference Proceedings / ISBN 978-0-9541183-9-6] ETH Zurich (Switzerland) 15-18 September 2010, pp.157-166
summary	This paper aims to address design education issues, with a focus on the way the contemporary metropolis is conceived. We understand the reality of the contemporary metropolis as an amalgam of specific issues that transcend local and regional contexts, converging into the categories of the so-called ‘global cities’. These new urban realities derive from territories originally controlled by other logics, and are now in new stages of post-industrial development. Thus, we notice the presence of large peripheral areas where existing industrial activities initially took place, which were later transformed and migrated, leaving behind urban fragments that are taken over by informal activities. Such sites are often crossed, when not ‘on-winged’, by transport infrastructure, increasingly essential to the growing intensity of metropolitan flows. Working with this new reality clearly means first and foremost to reexamine the tools and traditional methods of design and representation of the architect and urban planner.

title	The sensitive tower: Architectural and urban design education faced with fragile metropolitan ecologies
doi	https://doi.org/10.52842/conf.ecaade.2011.581
source	RESPECTING FRAGILE PLACES [29th eCAADe Conference Proceedings / ISBN 978-9-4912070-1-3], University of Ljubljana, Faculty of Architecture (Slovenia) 21-24 September 2011, pp.581-588
summary	Neighborhoods that are still outside the market target can find alternative ways of re-development. Therefore, it is necessary to design architectures compatible with their fragile ecologies. This research benefits from a previous study where we tried to observe the evolution of the uses of buildings and ways of living faced with changes in environmental conditions in a given urban context. Increased automobile traffic has led to changes in the use of residential spaces whose function was gradually replaced by commercial activities. Making use of graphic-oriented interpretation of urban ambiance and landscape analysis methodology applied to the design of different floor levels, this paper aims to introduce the concept of sensitive tower defined on the basis of observations made in our post-occupancy survey as a teaching strategy for the design studio faced with the current challenges of the contemporary metropolis.

title	Intersection of parametric Surfaces in the Bernstein-Bexier Representation
source	Computer Aided Design May, 1986. vol. 18: pp. 188-192 : ill. includes bibliography.
summary	A user-friendly 'divide-and-conquer' algorithm, which finishes quickly, is presented for finding all the intersection curves between two parametric surfaces in the Bernstein-Bezier representation. The underlying idea of the algorithm is to deal with the Bezier net instead of the surface description itself. By alternately subdividing the Bezier nets, and estimating the intersection area, a finite element mesh is created in the intersection region of the surfaces. The intersection is approximated by polygons computed by plane-plane-intersections using planes defined by Bezier points of the refined Bezier nets. Contour lines can also be produced by the algorithm

summary	For specific design criteria, rammed earth construction offers solutions as a concrete substitute since it has significantly less embodied energy. However, its typical construction process still utilizes wasteful formwork. Therefore, we propose to augment the principles of rammed earth by integrating renewable additives to improve the mechanical properties of the system towards richer geometry and developing a reusable waste-free formwork.

title	Practical Support for Collaborative Design Involving Divided Interests
doi	https://doi.org/10.52842/conf.acadia.1999.126
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 126-137
summary	Collaboration is common in design, yet relatively little is known about the cognitive reasoning processes that occur during collaboration. This paper discusses collaborative design, emphasizing the elaboration and transformations of the problem search space, and the roles that unstructured verbal communication and graphic communication can play in these processes. The paper discusses a prototype system called the Immersive Discussion Tool (IDT) that supports asynchronous design. IDT allows collaborators to mark-up 3-D models over the Internet using a variety of tools, including diagrammatic marks, dynamic simulations and text annotations. IDT relies on VRML to view the models, with an extensive Java-based interface on the backend powering the interactive construction and playback of graphical annotations, the management of threaded discussions, and the management of file input/output. The development of this tool has revealed the difficulty of constructing complex marks in a virtual 3-D space, and the initial implementation of IDT suggests several strategies for solving these problems.

title	Architectural Design and Virtual Worlds
doi	https://doi.org/10.52842/conf.acadia.1999.004.2
source	ACADIA Quarterly, vol. 18, no. 4, pp. 4-6
summary	The combination of architectural design and virtual world design has lead to a rapidly expanding area of study and possibly the birth of a new profession. The potential as well as the uncertainty in the area of virtual architectural design are challenging to anyone who is concerned with our living environment, whether it is physical or virtual. Living in the virtual realm has raised the attention not only of architects, but also philosophers, social scientists and the wider academic and professional community. The discussion and debate on cyberspace will certainly remain an important branch of virtual architecture. In this paper we explore the potential and implications of architectural design in virtual worlds.

summary	The forthcoming popularization of Self-driving Vehicles (SDVs) suggests a significant challenge in urban planning, as it enables new mobility patterns for urban citizens. While manufacturers have been developing visionary scenarios where cars become rentable mobile activity spaces, the impact of SDVs on the urban context is unclear. Through the analysis of the new social and technological functionalities developed by car manufacturers, and the projection of these functions into spatial scenarios of use within urban case study site, this paper explores the potential for the redesign of urban streetscapes to reclaim open spaces for pedestrian experiences and urban culture.

title	Electronic Art and Second Order Cybernetic: From Art in Process to Process in Art.
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	The goal of the paper presented below is to discuss partial results of a research which has been financed by the state sponsored agency FAPESP since 2007. Inserted in the research line Design Process, it aims to analyse connections between design process in electronic art and architecture, concerning the creation of mixed media spatialities, as well as present how each field can get the benefits from this analyses. Based on Grounded Theory methodology, a method of qualitative research which aims to understand “reality” from the meanings attributed by people for their experiences, the research has been started collecting data from bibliographical references, interviews with media artists, theoreticians and curators of electronic art and visits to media labs. Interviews and visits of media centers were taken in Europe while the researcher was as an exchange student in the Interface Culture Department in Kunstuniversität Linz, from March to September of 2008. By crossing data collected from the interviews and visits, with the cybernetic social system theory by Niklas Luhmann, and the discussion of an example of mixed media spatiality creation in the art field, this paper analyses how creative processes in digital era depends on different interdisciplinary relationships and how collaborative approaches are needed nowadays in the arts and architectural areas, seeing that artworks are always being influenced by their respective specific “mediality”. The aim of this paper is to discuss the relevance of the use of the cybernetic theory in digital culture, when concepts like participation, interaction and communication are some of the keywords, towards a “collective and distributed authorship”, and their reflects in the contemporary spatiality. The special interest in the comparison of art experience and second order cybernetics as a reference to architecture field is one of the findings of the paper. And, concerning the practical implication, due to cybernetics’ constant questioning of viability, adaptability and recursion, it should be able to point some ways to architects and artists´ works, especially if we consider that they never work in “ideal” conditions.

source	SIGraDi 2009 - Proceedings of the 13th Congress of the Iberoamerican Society of Digital Graphics, Sao Paulo, Brazil, November 16-18, 2009
summary	The aim of this paper is the discussion of aspects like accident and programming in the creative process in Media Art As a transdisciplinary and collaborative activity, it could be seen as a possibility for knowledge construction and sharing spaces. It also shows how media art practice can be used as a reference for the creative process in the architectural field. Building knowledge spaces through creative processes is a challenge based on the latest reconfiguration of the relations among artists, artworks and observers, which were enhanced after digital technology. Designing knowledge space as collaborative process, we assume that our examination contribute to any field by stimulating the transitions from analog to digital culture.

summary	Through the automation of folding of sheet metal components by a six-axis industrial robot we explored the integration of parametrically-driven design and fabrication tools and its real-world implementation. Developed out of research into new possibilities presented by direct programming of flexible, digitally-driven, industrial tools, this project intends to speculate about the future implementation of parametric modeling tools in the field of design, and associated new, parametrically variable, fabrication processes. We explored the relationship between designer and machine, between data and craft, and tested conjectures about scale of production, through the digital creation, physical cutting, mental tracking, robotic folding, manual riveting, and sometimes painful installation of five hundred and thirty two unique sheet metal components. Such evaluations give insight into possible trajectories for development of new models of fabrication processes, questioning the scale and intellectual scope appropriate for custom fabrication environments, and the implicit need to then evaluate the incorporation of digital craft in design pedagogy.

title	3D Scene Representation as a Collection of Images and Fundamental Matrices
source	INRIA Report
summary	The problem we solve in this paper is the following. Suppose we are given N views of a static scene obtained from different viewpoints, perhaps with different cameras. These viewpoints we call reference viewpoints since they are all we know of the scene. We would like to decide if it is possible to predict ano- ther view of the scene taken by a camera from a viewpoint which is arbitrary and a priori di erent from all the reference viewpoints. One method for doing this would be to use these viewpoints to construct a three-dimensional repre- sentation of the scene and reproject this representation on the retinal plane of the virtual camera. In order to achieve this goal, we would have to establish some sort of calibration of our system of cameras, fuse the three-dimensional representations obtained from, say, pairs of cameras thereby obtaining a set of 3-D points, the scene. We would then have to approximate this set of points by surfaces, a segmentation problem which is still mostly unsolved, and then intersect the optical rays from the virtual camera with these sur- faces. This is the most straightforward way of going from a set of images to a new image using the current computer vision paradigm of rst building a three-dimensional representation of the environment from which the rest is derived. We do not claim that there does not exist any simpler way of using the three-dimensional representation than the one we just sketched, but this is just simply not our point. Our point is that it is possible to avoid entirely the explicit three-dimensional reconstruction process: the scene is represented by its images and by some ba- sically linear relations that govern the way points can be put in correspondence between views when they are the images of the same scene-point. These images and their algebraic relations are all we need for predicting a new image. This approach is similar in spirit to the one that has been used in trinocular stereo. Hypotheses of correspondences between two of the images are used to predict features in the third. These predictions can then be checked to validate or inva- lidate the initial correspondence. This approach has proved to be quite e cient and accurate. Related to these ideas are those develo- ped in the photogrammetric community under the name of transfer methods which nd for one or more image points in a given image set, the corresponding points in some new image set.

summary	On a number of occasions after telling people about Corporate Design Foundation and what we do, their reaction is “well, business now understands the importance of design, right?” The answer is yes and no. There is, as they say, good news and bad news. A growing number of senior business executives do understand the possibilities of design. But many still do not. Unfortunately, the majority of mid-level managers do not. While there has been an increasing amount written about design in the business press, there has also been an equal amount in the general press which is misleading or just wrong. There is a great deal more to do.

source	Proceedings of the 3rd European Full-Scale Modelling Conference / ISBN 91-7740044-5 / Lund (Sweden) 13-16 September 1990, pp. 53-64
summary	This paper briefly examines five interrelated themes concerning the use of full-scale simulation models in architectural projects, in the context of research and professional practice. First, the meaning of design is discussed. Second, a multi-functional interpretation of building performance is presented. Third, the main reasons for simulating design projects, in general, and for using full-scale models, in particular, are summarized. Then the antecedent or prerequisite conditions for public participation to occur effectively are discussed. Finally, an overview of the use of full-scale simulation models in European workshops enables us to table four ma n classes of functions for full-scale models.

summary	This paper speculates on some of the inherent differences between computer graphics and conventional media when used in architectural design. It suggests that a lot of work and thought has gone into developing computer graphics as a medium for the development and expression of architectural ideas and examines some of the reasons that the fruits of this labor have been slow to fmd their way into the mainstream of the profession. This slowness to embrace rapidly developing technologies seems to be resulting in an ever widening gap between potential and the mainstream practice.

summary	We are engaged in the process of exploiting gestural signs and pedestrian postures for the purpose of utilizing additional possibilities through the creation of a new Wearable Electronic Garment, as medium for inscription. Animated, cyber-performers move, deform, and re-arrange themselves, augmenting the dimensions of expressiveness/meaning during performance. The cognitive approach produced by thinking in/out of these bodies will similarly trigger changes in consciousness, affecting content and virtual story telling. Together we explore the interaction of text/gestures as movement—as in dance, human day- to-day postures, and our capacity to embody and generate meaning. Cyber dancers use gestures in order to cybernetically inscribe them. The composed gestures become the source of intention that relates to itself; its communicating environment becomes a visualization of the self-reflexivity of both the dance and consciousness. The dance is between worlds of humans, cyber-humans, and the source language as transforms into the domain of visible thought.
