title	Posicionamiento de Volúmenes Arquitectónicos Mediante Algoritmos Evolucionistas (Positioning of Architectural Volumes by Means of Evolutionist Algorithms)

summary	Configurational studies involve the groups of elements fulfilling restrictions defined by the designer in Architectural design. According to its necessities and intentions, the planner distributes the components of the group in a certain tridimensional way, establishing a composition. This operative procedure implies a classification system according to typologies that respond to a bigger system, and this in turn to another, until the whole is obtained. From the beginning the pattern should satisfy form restrictions, as well as dimensional and positional restrictions for each part that conforms the whole. Functional requirements are attended for each object satisfying relationships of connectivity and adjacency among them. In this work the parts are restricted by their relative position to a central element. Evolutionary Algorithms (EA) are used to solve this type of problem. Using evolutionary metaphors they originate concepts such as "genes", "chromosomes", "mutation", "crosses” and " population " (among other), which come closer to one of the solutions looked for by the designer, under combinatory stochastic methods. The most appropriate use of EA corresponds to problems of complexity NP-completeness (for example, problems of generation of cases of composition), allowing an efficient although not exhaustive analysis. Applying this technique to the generation of architectural volumes, some obtained results are exemplified.

summary	This work is part of a long term research programme (Brown and Horton, 1992; Brown and Nahab, 1996; Bassanino, 1999) in which tests and studies have been carried out on various groups of people to investigate their reaction to, and interpretation of different forms of architectural representation. In the work described here a range of architectural schemes were presented using particular representational techniques and media. An experiment was then undertaken on two different groups; architects and lay people. They were presented with a number of schemes displayed using the various techniques and media. The responses are summarised and some comments are made on the effect of computers on perceiving architecture and on communicating architectural ideas arising from an analysis of the responses.

title	New Trends In Graphic Representation
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 501-506
summary	In terms of graphic representation, architectural & urban study drawings present some fuzziness related to the multiplicity of scales, to the representation of the urban dynamic and to the means of communicating the contents of these studies for different publics, clearly divided among lay and specialists. Since the 16th century there have been certain stimulating propositions to this theme that have had an enormous, often unacknowleged, impact on the perception and construction of the built environment. Recent experiences in Rio, due to the series of urban projects that are being accomplished, is showing that some architecture offices are adopting new graphic trends in drawings conceived for preliminary studies, diagnoses and inventories. Due to the new possibilities offered by graphic computing they are developing, with diferent softwares, a sort of "patchwork” or "collage” and "sampling” technique for morphological analysis and representantion of places and buildings. This use of graphic computing, as an alternative to the usual realistic depictions that attempts to deal with prosaic simulations of an everyday experience, results in a different type of graphic expression that transcend literalism and appealls to the imagination of the general viewer. It is important to highlight that the analysis of these graphic solutions that attempts to turn visible design problems, could result in the development of new graphic tools that will help the creative design process.

summary	This work presents the study and applied assays (or simulation tests) about the ordination of urban space in the region of Lagoa da Conceição. In the region pressures placed by the growth of urban area and urban network system are in contact conflict with a fragile ecosystem, and with a sustainable development based on tourism. Analysis procedures exploited different forms of Space Syntax trying to examine effects of spatial structure in relation to movement patterns of pedestrians and vehicles. This methodology allowed the comprehension of relation between spatial configuration, transport and soil use, and reveled the interdependence and performance of built space within the restrict regional scale (Lagoa da Conceição) and the total urban structure of the island. This understanding is not limited to the present. Is also includes the study of historic urban evolution, and simulation of existing projects for the future, being an important tool to support project decision process. Consequently, the obtained results bring a new approach for the problem, which makes possible the synthesis of design proposals verifying its implications and consequences.

title	The right tool at the right time : investigation of freehand drawing as an interface to knowledge based design tools
source	College of Architecture, Georgia Institute of Technology
summary	Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking about natural lighting, they draw a sun symbol and light rays. Given the connection between drawings and thinking, one should be able infer design intentions from a drawing and ultimately use such inferences to program a computer to understand our drawings. This dissertation reports findings from empirical studies on drawings and explores the possibility of using the computer to automatically infer designer's concerns from the drawings a designer makes. This dissertation consists of three parts: 1) a literature review of design studies, cognitive studies of drawing and computational sketch systems, and a set of pilot projects; 2) empirical studies of diagramming design intentions and a design drawing experiment; and 3) the implementation of a prototype system called Right-Tool-Right-Time. The main goal is to find out what is in design drawings that a computer program should be able to recognize and support. Experiments were conducted to study the relation between drawing conventions and the design tasks with which they are associated. It was found from the experiments that designers use certain symbols and configurations when thinking about certain design concerns. When thinking about allocating objects or spaces with a required dimensions, designers wrote down numbers beside the drawing to reason xviii about size and to calculate dimensions. When thinking about visual analysis, designers drew sight lines from a view point on a floor plan. Based on the recognition that it is possible to associate symbols and spatial arrangements in a drawing with a designer's intention, or task context, the second goal is to find out whether a computer can be programed to recognize these drawing conventions. Given an inferred intention and context, a program should be able to activate appropriate design tools automatically. For example, concerns about visual analysis can activate a visual simulation program, and number calculations can activate a calculator. The Right- Tool-Right-Time prototype program demonstrates how a freehand sketching system that infers intentions would support the automatic activation of different design tools based on a designers' drawing acts.

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.

title	IT or not IT? An Examination of IT Use in an Experimental Multi-disciplinary Teamwork Situation
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 370-373

summary	Leeds Metropolitan University is well placed to carry out research into multi-disciplinary team-working, as all the design and construction disciplines are housed in one faculty. Staff have set up an experimental project, TIME IT (Team-working in Multi-disciplinary Environments using IT) which examines ways of working in the design/construction process and how IT is used when there is no commercial pressure. Four groups of four students, one graduate diploma architect, and one final year student from each of Civil Engineering, Construction Management and Quantity Surveying have been working on feasibility studies for projects that are based on completed schemes or have been devised by collaborators in the Construction Industry. Students have been asked to produce a PowerPoint presentation, in up to five working days, of a design scheme, with costs, structural analysis and construction programme. The students are not assessed on the quality of the product, but on their own ability to monitor the process and use of IT. Despite this, aggressive competition evolved between the teams to produce the 'best' design. Five projects were run in the 1998/99 session. A dedicated IT suite has been provided; each group of students had exclusive use of a machine. They were not told how to approach the projects nor when to use the available technology, but were asked to keep the use of paper to a minimum and to keep all their work on the server, so that it could be monitored externally. Not so. They plotted the AO drawings of an existing building that had been provided on the server. They like paper - they can scribble on it, fold it, tear it and throw it at one another.

title	Integrating Databases, Objects and the World-Wide Web for Collaboration in Architectural Design
source	Proceedings of the focus symposium: World Wide Web as Framework for Collaboration in conjunction with the 11th International Conference on Systems Research, Informatics and Cybernetics, The International Institute for Advanced Studies in Systems Research
summary	Architectural design requires specialized vertical knowledge that goes beyond the sharing of marks on paper or the multi-casting of video images. This paper briefly surveys the state-ofthe- art in groupware and outlines the need for vertical and integrated support of synchronous and asynchronous design collaboration. The paper also describes a software prototype (WebOutliner) under development that uses a three-tier persistent object-oriented, web-based technology for a richer representation of hierarchical architectural artifacts using Apple’s WebObjects technology. The prototype contributes to earlier work that defined a framework for a shared workspace consisting of Participants, Tasks, Proposals, and Artifacts. These four elements have been found through observation and analysis to be adequate representations of the essential components of collaborative architectural design. These components are also hierarchical which allows users to filter information, copy completed solutions to other parts of the program, analyze and compare design parameters and aggregate hierarchical amounts. Given its object orientation, the represented artifacts have built-in data and methods that allow them to respond to user actions and manage their own sub-artifacts. In addition, the prototype integrates this technology with Java tools for ubiquitous synchronous web-based access. The prototype uses architectural programming (defining the spatial program of a building) and early conceptual design as examples of seamlessly integrated groupware applications.

summary	To researchers in every discipline, Internet is quickly becoming the dominating environment to do literature studies. Commercial bibliographic databases tend to be too general, are not up-to-date and require special skills and effort to be searched. On the other hand researchers also publish on the Web and collaboratively that can create indexes of relevant publications. CUMINCAD is a bibliographic index that compiles papers related to computer aided architectural design. Implemented with a database, it allows searching and browsing in the ways usual on the Web. It provides a "historical evolution" to learn from previous efforts and draws attention to older original works that could have been ignored because they could not be found on the Web otherwise. The authors believe that CUMINCAD will help focus future CAAD research and improve the education. CUMINCAD work started in 1998 and is available at www.fagg.uni-lj.si/cumincad/. This paper focusses on the design and development of the database and presents some ideas concerning its advanced use in the analysis of research efforts.

title	Computational Analysis of the Environmental Impact of Building Designs
source	Carnegie Mellon University, Pittsburgh
summary	Concem for the environmental implications of human activities is becoming increasingly important to society. The concept of current development that does not compromise future generations! abilities to meet their needs is a goal for many communities and individuals (WCED 1987). These concerns require the evaluation and assessment of the potential environmental impact of human activities so that informed choices can be made. Building construction and operation activities are of significant importance in view of a) national and intemational economies, 6) resource consumption, c) human occupancy, and d) environmental impact. For example, in the United States the built environment represents an extensive investment, both as an annual expenditure and as an aggregate investment. In the mid-l980’s, up to 30% of new and remodeled buildings had indoor air quality related complaints. Buildings also consume approximately 35% of the primary energy in the U.S. every year, resulting in the release of 482 million metric tons of carbon in 1993.I Methods developed to assess the environmental impact of buildings and development patterns can and have taken multiple strategies. The most straightforward and simple methods use single factors, such as energy use or the mass of pollutant emissions as indicators of environmental performance. Other methods use categorization and weighting strategies. These gauge the effects of the emissions typically based on research studies and use a weighting or effect formulation to normalize, compare, and group emissions so that a scalar value can be assigned to a single or a set of emissions. These methods do not consider the characteristics of the context where the emissions occur.

summary	Information Technology is always more accessible when we trying to imagine what the IT could be actually used. This situation is even more noticeable in the architecture field, and there are various technologies that have failed on delivering urgent needed education quality. Meanwhile, the tradition architecture education is evolving rapidly under the concepts of problem-based approach, knowledge reconstruction, and self-guided learning. "Education without institutional boundary" happens everyday in the classroom, and multi-direction learning modes have replaced the traditional single-direction teaching approach. The role of IT in the curriculum of architectural design education has become a subject of debate, scrutiny and experimentation in architectural schools. This paper will first outline the theory of applying team-oriented knowledge construction approach into studio teaching, the setup of our integrated digital design media environment is introduced; organization issue regarding the team formation and studio coordination is discussed; case studies are illustrated for demonstrating the methodology applied; and the student feedback is summarized to analysis the effectiveness of the approach.

title	Digital Architecture in CAD studio and Internet-based competition
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

title	The art of growth and the solution of cognitive problems
source	International Conference on Generative Art
summary	A cellular method is proposed as an alternative for a connectionist approach. The present method does not use connections between cells, but introduces a field concept instead. If the fields are determined in accordance with the transformations familiar from fractal theory, then the solutions of problems that have some symmetry are forms of remarkable beauty. This way, a link is proposed between generative art and problem solving. It is conjectured that the ‘black box’ nature of connectionist systems can be replaced by an approach in which the solution of a problem coincides with a vivid visualization, also if the problems at hand are of a high-dimensional nature.

title	Automated Cost Analysis of Concept Design BIM Models
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 403-418.
summary	AUTOMATED COST ANALYSIS OF CONCEPT DESIGN BIM MODELS Interoperability: BIM models and cost models This paper introduces the automated cost analysis developed for the General Services Administration (GSA) and the analysis results of a case study involving a concept design courthouse BIM model. The purpose of this study is to investigate interoperability issues related to integrating design and analysis tools; specifically BIM models and cost models. Previous efforts to generate cost estimates from BIM models have focused on developing two necessary but disjoint processes: 1) extracting accurate quantity take off data from BIM models, and 2) manipulating cost analysis results to provide informative feedback. Some recent efforts involve developing detailed definitions, enhanced IFC-based formats and in-house standards for assemblies that encompass building models (e.g. US Corps of Engineers). Some commercial applications enhance the level of detail associated to BIM objects with assembly descriptions to produce lightweight BIM models that can be used by different applications for various purposes (e.g. Autodesk for design review, Navisworks for scheduling, Innovaya for visual estimating, etc.). This study suggests the integration of design and analysis tools by means of managing all building data in one shared repository accessible to multiple domains in the AEC industry (Eastman, 1999; Eastman et al., 2008; authors, 2010). Our approach aims at providing an integrated platform that incorporates a quantity take off extraction method from IFC models, a cost analysis model, and a comprehensive cost reporting scheme, using the Solibri Model Checker (SMC) development environment. Approach As part of the effort to improve the performance of federal buildings, GSA evaluates concept design alternatives based on their compliance with specific requirements, including cost analysis. Two basic challenges emerge in the process of automating cost analysis for BIM models: 1) At this early concept design stage, only minimal information is available to produce a reliable analysis, such as space names and areas, and building gross area, 2) design alternatives share a lot of programmatic requirements such as location, functional spaces and other data. It is thus crucial to integrate other factors that contribute to substantial cost differences such as perimeter, and exterior wall and roof areas. These are extracted from BIM models using IFC data and input through XML into the Parametric Cost Engineering System (PACES, 2010) software to generate cost analysis reports. PACES uses this limited dataset at a conceptual stage and RSMeans (2010) data to infer cost assemblies at different levels of detail. Functionalities Cost model import module The cost model import module has three main functionalities: generating the input dataset necessary for the cost model, performing a semantic mapping between building type specific names and name aggregation structures in PACES known as functional space areas (FSAs), and managing cost data external to the BIM model, such as location and construction duration. The module computes building data such as footprint, gross area, perimeter, external wall and roof area and building space areas. This data is generated through SMC in the form of an XML file and imported into PACES. Reporting module The reporting module uses the cost report generated by PACES to develop a comprehensive report in the form of an excel spreadsheet. This report consists of a systems-elemental estimate that shows the main systems of the building in terms of UniFormat categories, escalation, markups, overhead and conditions, a UniFormat Level III report, and a cost breakdown that provides a summary of material, equipment, labor and total costs.

title	Feature-Based High Level Design Tools - A Classification
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 275-290
summary	The VR-DIS project aims to provide design support in the early design stage using a Virtual Reality environment. The initial brief of the design system is based on an analysis of a design case. The paper describes the process of analysis and extraction of design knowledge and design concepts in terms of Features. It is demonstrated how the analysis has lead to a classification of design concepts. This classification forms one of the main specifications for the VR-based design aid system that is being developed in the VR-DIS programme. The paper concludes by discussing the particular approach used in the case analysis and discusses future work in the VR-DIS research programme.

title	Visualisation of Design Using Animation for Virtual Prototyping

summary	Although recent technology in time-based representation has vastly improved, animation in virtual prototype design field remains the same. Some designers invest a huge amount of money in the latest visualisation and multimedia technology and yet may create even worse animation. They often cramp sequences resulting in many viewers failing to interpret the design positively as they miss a lot of vital information that explains the design. This paper basically reports the importance of film-making understanding for producing good virtual prototype animation. It will be based on a part of a research project on the use of time-based media in architectural practices. It also includes an empirical analysis of several architectural-based documentary films (including an interview with the film director) and past and present computer animation. This paper then concludes with recommendations of good techniques for making animated visualisation relative to the stage at which the animation is produced for better design decision.

title	Image and Shape: Two Distinct Approaches
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary	This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

title	An approach for the interoperation of web-distributed applications with a design model
source	Automation in Construction 8 (3) (1999) pp. 291-303
summary	This paper defines the data and inference requirements for the integration of analysis applications with a product model described by a CAD/CAE application. Application input conditions often require sets of complex data that may be considered views of a product model database. We introduce a method that is compatible with the STEP and PLIB product description standards to define an intermediate model that selects, extracts, and validates views of information from a product model to serve as input for an engineering CAD/CAE application. The intermediate model framework was built and tested in a software prototype, the Internet Broker for Engineering Services (IBES). The first research case for IBES integrates applications that specify certain components, for example pumps and valves, with a CAD/CAE application. This paper therefore explores a sub-set of the general problem of integrating product data semantics between various engineering applications. The IBES integration method provides support for a general set of services that effectively assist interpretation and validate information from a product model for an engineering purpose. Such methods can enable application interoperation for the automation of typical engineering tasks, such as component specification and procurement.

title	The Architect's Use of the Internet - Study of the Architectural Presentation Possibilities
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 363-368
summary	The Internet media is opening new horizons in communication and representation in architecture. However, its use today is superficial, limited, and without creativity. This study will explore theories, methods and examples of how the virtual space of the Internet can be used in its full potential. That means to present ways of observing, understanding, interacting, and communicating the space without precedents in architecture. The existent presentations made by architects in the Internet are in general poor and static. Through the comparative analysis of two presentations of the same architectural space in the Internet and the use of state of the art technology in the Internet, this study will show innovations that will make the exploration of the architectural space more attractive, dynamic and interactive. The main issues will be on one hand, the improvement in the communication of the design through the use of the Internet, and on the other hand, the rise of the standards in the quality of the architectural presentations. This work will project possible implications of the Internet in architecture.

title	Modelo Virtual Abierto de la Ciudad de San Juan (Open Virtual Model of the City of San Juan)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 470-474
summary	The purpose of the present work is to virtually rebuild the city of san juan that was completely destroyed by an earthquake in 1944. From an audiovisual, multimedial approach, it tries to be a contribution to the recovering of the collective memory. Through virtual reality techniques, a three dimensional model of the city central area has been built, as it was before the earthquake. It has been achieved a multidisciplinary, open model that sums up a great deal of information and allows: 1.) From a pedagogic approach: an opened window to new ways of knowledgement transmission, through visual virtual information. The virtual rebuilt has been reconsidered as a pedagogic and communicational tool; 2.) From a historic and morphologic approach: to obtain multiple readings and to revolution the way to manage categories in different analysis scales; 3.) In the future, the model would allow the possibility of an unlimited improvement by working in different scales. Furthermore it would allow to add information, an so to increase the research area or to go deeper into details not only in the phenomenological dimension of the objects but also in their logic significant dimension.
