title	Hacia una semiótica de la hiperciudad [Towards a Semiotics of the Hypercity]
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	This research is the summing up of an investigation carried out within the frame of a undergraduated architectural seminary at Facultad de Arquitectura y Urbanismo de la Universidad de Chile. During one semester, the research focused on finding the most relevant and recognizable features related with the globalization phenomena and the new technologies of communication that are taking place in the city. Inquiring new types of relationships which might be generating between citizens and their territory is the main achievement. More specifically, we want to explore new meanings that the contemporary city might have for people, from their different social, economical and cultural conditions. The analysis considers three points of view or definitions: Capitalist Definition, Political Definition and Sociological Definition.

title	Computer Visualizations in Planning
source	eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary	A wide range of visualizations have been developed and implemented as tools for urban simulations and visual impact assessment. These include: plans, diagrams, elevations, perspective sketches, renderings, modified photographs (photo renderings and photomontages), slide projections, scale models, movies, videotapes and computer graphics. In the last decade, graphical computer applications have proven to be an increasingly supportive tool in visualization and manipulation of graphical material. This study presents the state of the art of computer visualization in planning. More specifically, the use of web-based computerized visualizations for landscape visual simulation, with the aim to develop a system of visualization techniques as an aid to communicating planning and design scenarios for historically important landscapes and urban places, with particular attention to the city of Nablus in Palestine. This has led to the evaluation of possibilities and potentials of computer use in this field, and to the definition of the visual problems and challenges of the city of Nablus. This study will argue what extra one can draw from computerized visualizations, what is likely to be its impact on future planning and design research, and what this visualization experience really means for historical important locations as in Nablus. The study demonstrates that computerized visualizations can be a powerful tool in representing a cityscape in three-dimensions from different angels. Visualizations will allow better understanding of the components of the city, its landscapes, city features and the process of change. In this way it may provide new and better platforms for public participation in planning.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications

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.

summary	This paper will introduce the Digital Fabricators Exhibition, which I have had the pleasure of curating. The exhibition runs in parallel with the conference and was previously exhibited at the Royal Institute of British Architect’s Architecture Pavilion, in Birmingham and the Building Centre, London, during the spring and summer of 2004. The exhibition explores the relationship between architecture, manufacturing techniques and digital technology. The case studies demonstrate the use of digital design to inform the built environment from citywide scale to component assemblies of current and future architecture. The emphasis within the exhibition is on experiential and tactile architecture. The exhibition features an shortlist of projects from international leaders. Each project has been selected for the excellence of the architecture and to illustrate the relevance of wide range of digital fabrication techniques. The exhibition is site specific and the design and content has evolved with each location.

title	GEOMETRY AND ARCHITECTURE: NURBS, DESIGN AND CONSTRUCTION
source	Proceedings of the Fourth International Conference of Mathematics & Design, Special Edition of the Journal of Mathematics & Design, Volume 4, No.1, pp. 135-139.
summary	Geometry regarded as a tool for understanding is perhaps the part of Mathematics which is the most intuitive, concrete and linked to reality. From its roots as a tool to describe and measure shapes, geometry as ‘the space science’ , has grown towards a theory of ideas and methods by means of which it is possible to build and study idealised models, not only from the physical world but also from the real world. In graphic architecture thought, geometry usually appears as an instrumental support for project speculation. Geometric procedures are presented as representational resources for the graphic testing of reflection and for the exposition of ideas in order to build a logical order as regards representation and formal prefiguration. The fast rise of computing in the last decades has made it possible for architects to work massively and in a graphic and intuitive way with mathematical representations of tridimensional geometry, such as the NURBS . These organic surfaces of free shapes defined by vectorial curves have allowed access to a rapid generation of complex shapes with a minumum amount of data and of specific knowledge. The great development of modelling achieved by the digital media and the limitations in the technical and building areas and in the existence of materials which are coherent with the resultant shapes reveal a considerable distance between the systems of ideation and simulation characteristic of the computing era and the analogous systems of production inherited from the slow industrial development. This distance has been shortened by CAD/CAM systems, which are, however, not very accessible to the architectural field. If we incorporate to the development of these divergent media the limitations which are distinctive of the material resources and procedures of the existent local technology, the aforementioned distance seems even greater. Assuming the metaphor of living at the threshold of two ages (industrial-computing, analogical-digital, material-virtual) and the challenge of the new conceptual and operational tools in our field, we work in the mixture, with no exclusions or substitutions, proposing (by means of the development of informational complements) some alternatives of work to approach the issue under discussion from the Architecture Workshop.

title	Discoveries Throughout Conceptual Design
source	CAADRIA 2004 [Proceedings of the 9th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] Seoul Korea 28-30 April 2004, pp. 319-334
doi	https://doi.org/10.52842/conf.caadria.2004.319
summary	This paper describes current progress of an interview study of architects which considers how these individuals design, focusing on breakthroughs and unexpected discoveries made throughout conceptual design. The study considers creative outcomes that occur while these individuals are not intentionally designing, as well as when they are, with the intention of identifying and evaluating evidence of latent creative activity. While not described in this paper, issues of insightfulness, based on a Gestalt perspective, are also considered in the study. The completed interviews described in the paper suggest that, in order to achieve breakthroughs, designers adopt distinctive methods of disengaging from currently unproductive designing. These may be categorized by degree and type of disengagement, or subsequent re-engagement. In general, disengaging, instead of persisting in designing, when apparently stuck, appears to be the rule rather than the exception. Statements by the interviewees suggest that discoveries during, or just after, times when they are not actively designing, referred to as cold discoveries, are more important than is currently recognized, which is scarcely at all. Statements describing interviewee experiences of discovery and providing indications of the genesis of discoveries are included in the paper. The paper discusses implications of the wide range of perceptions and experiences of each individual. One interesting finding is that individuals appear to experience and appreciate cold discoveries regardless of differences in key aspects of the way they design, described in the paper. This suggests that the genesis of cold discoveries may be as complex as that of discoveries in general.

title	View from the Road: Environmental Simulation for the Fractal City of Rhine Ruhr
source	Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 43-47
summary	Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

summary	We consider the problem of automating the recoloring of designs whose “originals” are defined using color look-up tables. Given a digital image , we assume for each pixel of there exists an integer index such that . If is a color look-up table of size , we say image is colored by if each pixel is assigned color . Given a map from to itself, we recolor by assigning to each pixel the color . We are able to evolve the recoloring maps by representing them as -tuples. We automate their evolution by applying multi-objective optimization. Examples of recolorings of designs that were originally in color and originally in black and white are given. Keywords.

doi	https://doi.org/10.52842/conf.ecaade.2004.480
summary	By inter-relating CAD and satellite image earth-viewing tools at building specific, city-wide and larger global scales, a wider framework of observation yields insight into the connectedness between built environments and tracking influences between them. The technologies for visualization and analysis at distinct scales are moving towards greater integration. This project demonstrates integration through three case studies, each at a different scale of application, and considers performance issues and implications for more general use. More specifically, CAD, GIS and now Satellite Image Based Earth Viewing systems all have found separate application within Architecture, Urban Planning and Strategic Regional Analysis This paper reports on an effort to test the tighter coupling of these systems on three projects, each at a different scale: (1) urban and regional scale, (2) continental scale, and (3) hemispheric analysis scale.

summary	This article is about an experience in the course of .Informática Aplicada à Arquitetura. for architecture students, at the Universidade Estadual de Londrina, applied on the the 2nd year, in a period between 1998 to 2003. We present an evaluation of three moments of this experience, thinking of the representation, the use of images and the easy way of constructing digital objects. The intentions were integrate theoretical knowledge on the space and digital three-dimensional exercises. From all experinces, all the process, exercises and their results we can stand out two reflections: the danger of the image used as a discard object and the construction of forms without conscience.

title	A semantic indexation method to assist with the architectural design process by images
source	SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary	A lot of research shown that designing an architectural solution requires introducing external references other than those existing in the design problem. In our case we choose photographic images to illustrate these references because an image illustrates the graphic part of an architectural concept. For this the information transmitted by photographic image is often easier to interpret by the designer. To assist the design process, we are working on the construction of a reference image database where the designer will find various solutions to his design problem. We have therefore proposed a method for indexing this image database. The following paper tackles the particular question of semantic meaning applied to architectural works. More precisely, we present the results obtained through an experiment following the Chi-square statistic rule, whose objective was to validate the weight associated with the architectural concepts illustrated according to their visual features in images.

title	The Kaléidoscope System to Organize Architectural Design References
source	International Journal of Architectural Computing vol. 2 - no. 3, 351-369
summary	The presentation of a new computer-based tool to assist architectural conception demands reflection on the process of creation itself. There is an articulation between typical conceptual procedures and computerized means. We chose one of these procedures: the utilization of external references (not necessarily architectural) to stimulate new design ideas. This is the basis for the experimental computational model "kaléidoscope", which is characterized as an open reference system for architectural design. There are two essential qualities for such a system: 1) The system should permit an individual interpretation and construction of the referential knowledge, considering that 2) references may proceed from fields other than architecture. The computational model begins with a reference, formed by the association of an image to concepts and / or texts. The concepts are graphically represented and organized in thematic thesauri. The "kaléidoscope" system includes several search and navigation modes, allowing access to references as a means to rouse new design ideas.

summary	The dynamics of the city today, their conceptual changes and physical migrations place us in front of an indicial rather than symbolic phenomenology where the visuality of the of the image requires to rethink the conceptual categories for the projectual action. As architects, professors and investigators we find ourselves in front of the necessity to focus from the environment of the investigations of the coetaneous city, the system of the diverse morphologic assemblies of the urban condition, the different intervening graphologic entities and the textualities of the image in the configuration of the urbanity. It is proposed to give continuity to the presentations of investigative short essays of Sigradi 2003 and inquires of the communicational sense approached in 2004, introducing in this event schemes of investigation-teaching, exhibiting proposals of objects and designs in urban environment of the Laboratory of Formal Explorations, emphasizing the revaluation of the areas of obsolescence, the insertion of the novel outdoor public spaces and new emergent forms of the dispersion and territorial decentralization."

title	How to Construct an Audience in Collaborative Design - The Relationship Among which Actors in the Design Process
source	Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 426-434

summary	The features of complexity in architectural design have now been clarified. Complexity, intrinsic in architectural work, has increased in recent years as in all other fields of human endeavour – social, economic and cultural. In the specific case of architectural design, the most significant factors in this regard consist of the large number of actors, the numerous disciplines involved, technological innovation, regulations and rules governing the design process and the various different design aims. In order to address this complex of problems, long-term research based on the Collaborative Design paradigm, CD, is now being carried out. In it, thanks to the reciprocal exchange of information, the complementary nature of the knowledge possessed by the various actors, and the contemporary nature of the design action by the various actors on the same components, positive effects are exerted on the design as a whole. The latter thus gains in coherence and in improved integration among the design solutions proposed by the various actors. In CD all the actors are involved from the outset of the design work and are helped by distributed Knowledge Bases (KBs) and Intelligent Assistants (IAs). In this case it may happen that information and knowledge automatically exchanged among KBs (through the IAs) are excessive and/or not addressed to the right actors. How can information redundancy be avoided, and how can the flow of information sent over the network be controlled? The present paper introduces and defines the concept of „Audience“, that is, the group of actors to which it is permitted to send information concerning non respected requirements and the „reduced Audience“ to which to send the knowledge needed to overcome the difficulties encountered.

summary	The problems of inspecting urban design proposals are different to that of architecture. The larger context is a crucial aspect in urban design. Generally the issues are not of detailed design but rather understanding space and spatial features. Discussions about proposals use plans and large urban design models. The models are cumbersome and access difficult for collaborative consultation. This paper introduces a prototype for an Augmented Reality system for analyzing and representational design in an urban design scale. The system is designed as a workbench for collaboratively and dynamically exploring in an urban design model.

title	FROM REPOSITORY TO RESOURCE -- EXCHANGING STORIES OF AND FOR ARCHITECTURAL PRACTICE
source	Journal of Design Research, Volume 4, Issue 1, 2004 [ISSN 1569-1551]
summary	Central to Case-Based Reasoning (CBR) is the claim that knowledge in human memory takes the form of cases, i.e. interpreted representations of concrete experiences. The intimate relationship between knowledge and experience in design has inspired CBR researchers to develop various Case-Based Design tools, which try to support architects (and designers in general) in capitalizing on previous design experience. Typically, these tools is built around a case base, an indexed collection of concrete cases labeled by a set of characteristic features. In general, cases document buildings, i.e. design products. By contrast, Building Stories has chosen to complement product data by stories about the process that generated the product. Previous papers have documented and illustrated the ideas underlying Building Stories and situated the methodology with regard to other case study approaches. The present paper focuses on establishing the growing repository of building stories into a valuable resource of and for the profession.

title	A computer Based System for the Design and Fabrication of Tensegrity Structures
source	Fabrication: Examining the Digital Practice of Architecture [Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 0-9696665-2-7] Cambridge (Ontario) 8-14 November, 2004, 100-109
doi	https://doi.org/10.52842/conf.acadia.2004.100
summary	Tensegrity structures are composed of tension compression components, where the compression components (bars) are discontinuously enclosed within continuous tensile components (cables). From an engineering point of view, a tensegrity structure is characterized by geometric non-linearity and large displacements under loading. Therefore, its prestressed shape and deformation under loading are the result of the combined effect of the geometric parameters that determine the initial configuration of the structure, the level of prestress applied to cables, and the material properties of the component members of the structure. A method for generating the initial geometric configuration of tensegrity structures composed of tensegrity units and a parametric expression of this geometry have already been developed. A novel technology that makes possible the construction of tensegrity structures from the on-site assembly of deployable tensegrity units, which are furnished with a simple mechanism that permits bar-elongation, and, as a result, an increase of the prestress applied to the cables of each unit, is also under development. Also under development is a static analysis method that takes into account the above method for prestressing cables. This paper discusses the features of a system that supports the combined geometric and structural design of tensegrity structures, and integrates a graphical interface to display: a) models of initial geometry, b) geometry of the structure after prestress and loading are applied, and c) magnitude of forces applied to the structure’s component members (bars and cables). The system also provides numerical data to be used in component fabrication, and is therefore expected to become a very valuable tool for the design and construction of tensegrity structures.

summary	Architecture in reality is perceived mainly through the display of space enclosures of different degrees, ranging from complete enclosure to openness. These degrees of enclosure are characterized either by subtle or often exuberant display of interplay between solids and voids. Mass and wall are the key features that play an important role in the formation of any specific relationship that develops between solids and voids. The level of relationship between wall and mass therefore is critical in shaping the overall appearance of the work. As we look back in time, walls were simply used as means of enclosing the space that was to hold specific functions. Here the obvious priority is assigned to the space and the walls are simply enslaved in order of hierarchy. But, as the history of the built environment progressed with time, this pattern of relationship was challenged and being experimented by various architects. The experiments ranged from subtle variations in the thickness of wall with regard to the associated mass, or by emphasizing its existence by the use of varying height, color, texture, etc., or even by separating it from the mass that was believed to be the mother form in earlier days. Instead of being secondary to the space it enclosed, walls started taking the primary role in terms of announcing its existence. This of course is not the only path taken by architects. As always, design concept and approaches vary from one person to the other and so does the ultimate result. This change in the pattern of relationship plays a major role in developing the formal language of contemporary architecture which needs to be acknowledged. The aim of this paper is to identify the distinct deviations in the pattern of relationship between mass and wall by depicting some of the significant works of 20th century. The role of 3D computer modeling and various animation techniques to illustrate these analytical ideas is a highlight of the presentation.

summary	Municipal governments or developers make design guidelines to create harmonious streetscapes in new towns. The regulations, however, are often based on arbitrary decisions without any empirical research. The present study employed a visual simulation system to test the effects of such physical features of the buildings as color, height, flatness of the building façade and its recess from the street on pedestrians’ impressions of the place. Thirty subjects were asked to rate their impressions of “order”, “simple”, and to evaluate the atmosphere after experiencing the simulated scenes. The results revealed some relations between the physical features and the pedestrians’ responses.
