title	CAD – The Creative Side - An Educational experiment that Aims at Changing Students’ Attitude in the Use of Computer-Aided Design
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 218-221
summary	The present paper describes an innovative design education system tried out at two different architecture schools in Brazil, with opposite approaches to the use of CAD. The experimental courses had two main goals: (1) to explore the use of logical operations in design, such as symmetry, recursion, parameterization, and combinatorial analysis, and (2) to apply these techniques with the use of the computers, using CAD not only as a representational tool, but rather as an explorative, customizable and programmable design aide for the creative process. The experiments resulted in a number of interesting compositions, design projects and programs, and assessment questionnaires revealed a real change in students’ attitude towards the use of CAD in architecture.

title	Intelligent approaches for generating assembly drawings from 3-D computer models of mechanical products
source	Computer-Aided Design, Vol. 34 (5) (2002) pp. 347-355
summary	In order to reduce the time of mechanical product design and ensure the high quality of their assembly drawings, this paper develops an intelligent approach for generatingassembly drawings automatically from three-dimensional (3-D) computer assembly models of mechanical products by simulating the experienced human designer's thinkingmode with the aid of computer graphics and knowledge-based expert system. The key issues include the strategies and methods for selecting the necessary views in anassembly drawing, determining necessary sectional views in each view, eliminating the unreasonable projective overlap of the components in each view, and minimizing thenumbers of both the views in an assembly drawing and the sectional views in each view. Based on the approach, corresponding software prototype was developed. Finally, itis demonstrated, from an example of the fixture in a modularized drilling machine, that its assembly drawing was generated successfully using this intelligent softwareprototype.

title	A Computer Solar Analysis Tool for the Design and Manufacturing of Complex Architectural Envelopes: EvSurf
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 105-109
summary	Heat flows (gains or losses) in a building are affected by solar radiation, internal gains and temperature differences. A prototype of a tool that evaluates solar radiation on building envelopes has been developed as an applet to run on the Internet. This tool analyses the relationship of the solar position with the surfaces of complex envelopes by evaluating the potential amount of direct solar radiation that each surface section receives as a function of the angle of each surface with the sun for specific days and latitudes. A fitness function rates the overall performance of the proposed building envelope at specific hours or whole days, permitting to compare alternatives. Because of its characteristics, this tool is a Very Simple Design tool that works interactively with the user during the design process helping to design solar responsive building envelopes.

title	O real, o virtual e a Internet na era da Informação [The Real, the virtual and the Internet in the Information Age]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 28-30
summary	Over the last decade, advances in computer graphics plus the growing popularity of the Internet have incorporated the words reality and virtuality into our vocabulary, at the same time, making the distance between the words shorter. In this article, we discuss the two concepts - reality and virtuality - and analyze how this question has affected human communication, specially in the Web environment. This analysis will be used as a basis for research on the impact of “non-presence” in working relationships in a virtual environment, more specifically in the architecture and engineering areas where we find the Web being used as a communication tool for the development of collaborative design between groups involved with the design process of the built environment.

title	Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary	Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

summary	“Genetic architectures”, not only like a metaphorical name. New materials and new tools give a new architecture. Up to now the human being had to conform with acting only at the superficial level of objects. Now, it’s possible to think further away and descend to actions at the molecular level, influencing on genetic design and on programming chains which are then developed by themselves as artificial computing elements and natural live elements. It’s time to apply all these to architecture, when these can become an integrating part of architecture. These should include an advanced contemporary architecture versus (and basing itself on) the use of the computer as a mere substitute of manual drafts while improving pintoresque ecology: “the new cibernetic-digital architectural design & the new ecological-environmental architectural design”. Not building in the nature, building with the nature, building the nature self. The utopy of today is the reality of tomorrow.

title	Situated Computing: A New Paradigm for Design Computing
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, p. 1
summary	Computer usage in design has largely been in the areas of document production, 3D modelling and to a lesser extent in specialised design analysis and design synthesis tasks. This use of computers by designers has been based on well-defined practices that have their genesis in the scientific approach to knowledge. Just as knowledge is independent of its use and independent of its user, so computer programs are designed to be independent of their use and independent of their users. This talk presents a complementary paradigm based on the notions of situated cognition as the basis of the development of new kinds of computational design tools.Situated cognition holds that where are you and when you are there matters and that the state you are in affects what you do. The fundamental difference is between encoding all knowledge prior to its use to allowing the knowledge to be grounded in the interaction between the computational system and its environment. In addition to the concepts of situated cognition there is another important concept called constructive memory. Constructive memory changes our view of “memory” in acomputational system from being a thing in a place that can be accessed with the correct index to being a process that produces a “memory” when needed. Thus, memory is constructed as needed and becomes a function of both the question it is used to respond to and the situation within which it was asked. These concepts provide the foundation for the developmentof novel tools to support computer-aided designing. Examples of situated cognition and constructive memory will be presented. This will be followed by examples of situated design analysis and situated computational design creativity.

title	Prêt-à-Construire – An Educational Inquiry into Computer Aided Fabrication
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 162-165
summary	This paper aims to show and discuss the relevance of developing necessary strategies for reintegrating the concept of fabrication into the architectural design process. The discussion will be partly based on the outcome of a graduate architectural design studio conducted in Spring semester 2002-2003. The graduate studio was part of a series of exploratory studies conducted on the nature of architectural design process transformed by information technologies. Preceded by studios investigating cognition and representation, this last studio focused on the concept of fabrication. The overarching aim of the studio series was to put CAD and CAM in context both within the actual architectural design process and within architectural education. The last of this series, which will be discussed within the frame of this paper, has specifically focused on CAM and the concept of fabrication in architecture. In accordance with the nature of a design studio, the research was more methodological than technical. The studio derived its main inspiration from the constructional templates used in dressmaking, which can be considered as an initial model for mass customization. In this context, the recladding of Le Corbusier’s Maison Domino was given as the main design problem, along with several methodological constraints. The main constraint was to develop the design idea through constructional drawings instead of representational ones. The students were asked to develop their volumetric ideas through digital 3D CAD models while working out structural solutions on a physical 1/50 model of Maison Domino. There was also a material constraint for the model, where only specified types of non-structural paper could be used. At this stage, origami provided the working model for adding structural strength to sheet materials. The final outcome included the explanation of different surface generation strategies and preliminary design proposals for their subcomponents. The paper will discuss both the utilized methodology and the final outcome along the lines of the issues raised during the studio sessions, some of which could be decisive in the putting into context of CAD – CAM in architectural design process. One such issue is mass customization, that is, the mass production of different specific elements with the help of CAM technologies. Another issue is “open source” design, indicating the possibility of a do-it-yourself architecture, where architecture is coded as information, and its code can be subject to change by different designers. The final key issue is the direct utilization of constructional drawings in the preliminary design phase as opposed to representational ones, which aimed at reminding the designer the final phase of fabrication right from the beginning. Finally, the paper will also point at the problems faced during the conduct of the studio and discuss those in the context of promoting CAM for architectural design and production in countries where there is no actual utilization of these technologies for these purposes yet.

doi	https://doi.org/10.52842/conf.acadia.2002.279
summary	In this paper, we present a user-friendly and practical method for seamless integration of computergeneratedimages (CG) with real photographs and video. In general, such seamless integration isextremely difficult and requires recovery of real-world information to simulate the same environment forboth CG and real objects. This real-world information includes camera positions and parameters,shapes, material properties, and motion of real objects. Among these, one of the most important islighting.Image-based lighting that is developed to recover illumination information of the real world fromphotographs has recently become popular in computer graphics. In this paper we present a practicalimage-based lighting method that is based on a simple and easily constructable device: a square platewith a cylindrical stick. We have developed a user-guided system to approximately recover illuminationinformation (i.e. orientations, colors, and intensities of light sources) from a photograph of this device.Our approach also helps to recover surface colors of real objects based on reconstructed lightinginformation.

title	BEYOND ANALYSIS AND REPRESENTATION IN CAD: A NEW COMPUTATIONAL APPROACH TO DESIGN EDUCATION
source	Submitted to the Department of Architecture in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the field of Architecture: Design & Computation at the Massachusetts Institute of Technology
summary	This thesis aims at changing students' attitude towards the use of computer-aided design (CAD) in architecture. It starts from the premise that CAD is used mostly for analysis and representation, and not as a real design aide, and that architecture students have a bias against learning computer programming. For this purpose, a prototypical instruction system that mixes computer-aided design and computational design theory was developed, based on a series of fundamental concepts that are common to both fields. This system was influenced by Mitchell's (1987) The Art of Computer Graphics Programming and Stiny's (1976) shape grammars. Despite being based on solid theoretical foundations, CAD has progressively become an exclusively practical tool, since its origins in the 50's and 60's, while computational design theories have been mostly restricted to the academic circles. This thesis proposes an inversion in the present situation: the study of CAD theory, and the application of computational design into practice. The system proposed provides a conceptual framework that can be adapted to different circumstances, including course formats and resources, as well as students' background and technical training. It is based on seven fundamental concepts from computational design theories that are also important to the study of shape grammars: symmetry, recursion, rule-based compositions, parameterization of shapes, generative systems, algorithmization of design procedures, and shape emergence. These concepts are introduced within a CAD context, where their practical implementation and experimentation are possible, focusing the understanding of the computational nature of design. During this research, the proposed system was tested in two case studies with students from schools that had contrary orientations in terms of the importance of CAD in the architectural curriculum. In these experimental courses, students' activities evolved from using a commercial CAD tool in an innovative way, to the use of programming techniques for creating meaningful tools. Despite not having a statistical reach, the fieldwork allowed drawing preliminary conclusions about the proposed system's efficacy, since virtually all the students reported changing their understanding of the role of CAD in architecture, while some also acknowledged a conceptual influence in other subjects and in the way they see architecture.

doi	https://doi.org/10.52842/conf.ecaade.2002.464
summary	The first generations of computer aided design systems were largely characterized by geometrical modeling software that could, in some applications, generate physical output in the form of computer aided manufacturing. More recently the technology has expanded to include a variety of ways to reverse direction, such that physical objects are captured and translated into computer graphics geometrical models. Laser surveying methods that produce point clouds are among the newer technologies that make this possible. The interpretation of the point clouds and translation of them into a computer graphics three-dimensional model can be subject to various mediation processes. This paper reports on a translation environment that interprets the point clouds so as to not just replicate the physical world, but rather encapsulates it towards the refinement and realization of geometry design objectives. A case study of Fountains Abbey, a Cistercian Abbey in the United Kingdom, serves as the basis for experimentation and control of surface geometry.

title	Predicting the Past, Remembering the Future
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 2-3
summary	Charlas Magistrales 2There never has been such an exciting moment in time in the extraordinary 30 year history of our subject area, as NOW,when the philosophical theoretical and practical issues of virtuality are taking centre stage.The PastThere have, of course, been other defining moments during these exciting 30 years:• the first algorithms for generating building layouts (circa 1965).• the first use of Computer graphics for building appraisal (circa 1966).• the first integrated package for building performance appraisal (circa 1972).• the first computer generated perspective drawings (circa 1973).• the first robust drafting systems (circa 1975).• the first dynamic energy models (circa 1982).• the first photorealistic colour imaging (circa 1986).• the first animations (circa 1988)• the first multimedia systems (circa 1995), and• the first convincing demonstrations of virtual reality (circa 1996).Whereas the CAAD community has been hugely inventive in the development of ICT applications to building design, it hasbeen woefully remiss in its attempts to evaluate the contribution of those developments to the quality of the built environmentor to the efficiency of the design process. In the absence of any real evidence, one can only conjecture regarding the realbenefits which fall, it is suggested, under the following headings:• Verisimilitude: The extraordinary quality of still and animated images of the formal qualities of the interiors and exteriorsof individual buildings and of whole neighborhoods must surely give great comfort to practitioners and their clients thatwhat is intended, formally, is what will be delivered, i.e. WYSIWYG - what you see is what you get.• Sustainability: The power of «first-principle» models of the dynamic energetic behaviour of buildings in response tochanging diurnal and seasonal conditions has the potential to save millions of dollars and dramatically to reduce thedamaging environmental pollution created by badly designed and managed buildings.• Productivity: CAD is now a multi-billion dollar business which offers design decision support systems which operate,effectively, across continents, time-zones, professions and companies.• Communication: Multi-media technology - cheap to deliver but high in value - is changing the way in which we canexplain and understand the past and, envisage and anticipate the future; virtual past and virtual future!MacromyopiaThe late John Lansdown offered the view, in his wonderfully prophetic way, that ...”the future will be just like the past, onlymore so...”So what can we expect the extraordinary trajectory of our subject area to be?To have any chance of being accurate we have to have an understanding of the phenomenon of macromyopia: thephenomenon exhibitted by society of greatly exaggerating the immediate short-term impact of new technologies (particularlythe information technologies) but, more importantly, seriously underestimating their sustained long-term impacts - socially,economically and intellectually . Examples of flawed predictions regarding the the future application of information technologiesinclude:• The British Government in 1880 declined to support the idea of a national telephonic system, backed by the argumentthat there were sufficient small boys in the countryside to run with messages.• Alexander Bell was modest enough to say that: «I am not boasting or exaggerating but I believe, one day, there will bea telephone in every American city».• Tom Watson, in 1943 said: «I think there is a world market for about 5 computers».• In 1977, Ken Olssop of Digital said: «There is no reason for any individuals to have a computer in their home».The FutureJust as the ascent of woman/man-kind can be attributed to her/his capacity to discover amplifiers of the modest humancapability, so we shall discover how best to exploit our most important amplifier - that of the intellect. The more we know themore we can figure; the more we can figure the more we understand; the more we understand the more we can appraise;the more we can appraise the more we can decide; the more we can decide the more we can act; the more we can act themore we can shape; and the more we can shape, the better the chance that we can leave for future generations a trulysustainable built environment which is fit-for-purpose, cost-beneficial, environmentally friendly and culturally significactCentral to this aspiration will be our understanding of the relationship between real and virtual worlds and how to moveeffortlessly between them. We need to be able to design, from within the virtual world, environments which may be real ormay remain virtual or, perhaps, be part real and part virtual.What is certain is that the next 30 years will be every bit as exciting and challenging as the first 30 years.

summary	The proposal of “Urbamedia” is to undertake the development of a 3D virtual and interactive model of an historical area of the city of Buenos Aires. The selected zone is the “Mayo Avenue” including the “Mayo Square”; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting and experimental model of the “Mayo Square” that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. We are also looking to include histórical areas of three cities (Mar del Plata, Rosario and Santa Fe) and eventually other cities from Latin América. Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulationsof the environmental parameters.

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.

title	CAD/CAM Methods in Support of Historic Preservation: A Case Study of the Freeman House by Frank Lloyd Wright
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 52-54
summary	Preservationists have an impressive array of digital tools to aid them in documentation and analysis of historic structures. The tools range from near photo-realistic renderings to demonstrate what a “restored” building might have looked like at one specifi c time in history to complex chemical analysis of paint chips and pigments to geographic information systems used as management tools for historic prop er ties. Computer-aided design / computer-aided manufacturing (CAD/CAM) is set of important digital aids in historic preservation efforts. This paper presents a case study of the use of CAD/CAM in support of an effort to restore a textile block house designed by Frank Lloyd Wright. CAD/CAM methods are being employed to help produce a new mold so that new textile blocks can be manufactured that match the existing blocks. An existing textile block mold was digitally scanned, digitally mirrored and edited, and will be fabricated from an aluminum billet to replace a mold that no longer exists. Although seemingly a simple process and well within current technological abilities, the work proved substantially more challenging that initially imagined.

title	Archivo Digital de las Obras de Arte de la Ciudad Universitaria: experiencia en el Pregrado de Arquitectura [Digital File of Art of the University City: Degree Experience in Architecture]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 240-244
summary	This article describes the experiences in the teorical – practical course “Computer Asisted Design – Level II” in the Architecture career, offer by the LTAD - FAU – UCV. We gave as models to the students of our course real art works, located and visitable in the universiy campus, offering the construction of detailed digital files of them, that will be publish in Internet. Files that can be use in the inventary and conservation of those art works. Important exercise if we consider that this art works are part of theUNESCO Human Cultural Patrimony (http://www.unesco.org). We want that our University asumes this iniciative as integral part of the inventary, conservation and divulgation of the art works integrated to the buildings in the UCV Campus.

title	Context, Practice and Technique in the Development of a Creative Curriculum
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 39-42
summary	This paper explores ideas in relation to the design and delivery of a university level curriculum aimed at producing computer artists. Theessential principle is that the organisation of the film industry is a useful paradigm, and that the paradigm can be used as a tool in the designand delivery of this kind of curriculum. The education of graduates destined for the “new media” industries is complex. A particular problemis to achieve balance between development of technological skills on the one hand and artistic and creative development on the other. The challenge for educators is that many students are motivated by acquiring technical expertise and may not realise the importance of artistic and creative development. Comparisons with the world of film are used to address the problem of balance. The background to this approach is discussed and some preliminary results, in terms of student attitudinal change, are described.

title	Participatory Design in Collaborative Virtual Environments
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 159-162
summary	This paper re-establishes the theoretical framework for participatory design evolved in the late sixties and early seventies as part of the movement towards a more explicit design methodology and attempts an explanation of why the concept failed to gain commitment from the architectural and urban design professionals. The issue of user participation in the processes of building and urban design is enjoying renewed attention following its relative neglect over the last 20 years due, in large measure, to significant advances in emerging information technologies, particularly multimedia, virtual reality and internettechnologies. This paper then gives an account of two significant and relevant developments in the evolution of the application of informationtechnologies with which the authors have been engaged. These are:a responsive and interactive interface to wholly immersive and realistic virtual reality representations of proposed buildings and urban neighbourhoods. an intuitive and platform-independent VR modelling environment allowing collaborative evolution of the scheme from withinthe virtual world. The efficacy of these IT developments is tested in the context of a design exercise in which three designers, from distributedlocations and using different computer platforms, collaboratively design an Information Centre from within the virtual world.

title	O sistema “Kaléidoscope” de organização de referências ao projeto arquitetural [The system "Kaléidoscope" for reference organization in architectural design]
source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 129-132
summary	Our research focuses on how to create new types of computer tools, which aims to help early architectural design phase. Therefore we constructed a prototype named “kaleidoscope “. This system is based on the notion that architects use some external references as a strategy to construct new project ideas and that it is possible to organize this referential knowledge.This article presents four guide-lines which allowed the development of the first version of “kaleidoscope” system. As we succeed in broadening and deepening our knowledge - theoretical and empirical – about computers, wediscover that in large part their behavior is governed by simple general laws, that what appeared as complexity in the computer program was to a considerable extent complexity of the environment to which the program was seeking to adapt its behavior.
