title Peter Eisenman’s House X, Scheme G: 3D Game Engine for Portable Virtual Representation of Architecture
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 526-531
summary Recently introduced 3D games, game editors, along with gaming software offer great potential for delivering three-dimensional, collaborative virtual environments for online audiences. These capabilities have significant potential in architectural visualization. The University of Missouri-Columbia’s Emerging Technology Group developed the Virtual Campus Project introducing the university campus to prospective students through the Internet. Fascinating quality, seamless real time rendering, and smooth navigation are enough to impress visitors. However, the developers had to use eye measures and guesses based on photos rather than architectural drawings for initial 3D computer models. The absence of a precise scaling system as well as not being able to recognize a standard 3D architectural drawing format in a virtual environment were the prime generators of this paper. One important goal for this paper is to suggest architects the potentials of using universal or exchangeable formats of 3D models with accurate structure data to build virtual models. A second goal is to provide better understanding of potentials in 3D game engines for virtual representation of 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 Modular Perspective as a Method for Generative Design
source International Conference on Generative Art
summary Apparently there are many methods for perspective but if we categorize them there are just a few. Some criterions of classification relate perspective to the so-called 1-point, 2-point and 3-point methods, others —more formally— to projective geometry, descriptive geometry or vectorial algebra. Of course we cannot forget to mention the early treatises on perspective such as Alberti’s Della Pittura or Piero’s De Prospectiva Pingendi, which escapes any classification. Our aim on this article is not precisely to solve the classification problem rather we propose a new comprehensive method for perspective, capable of 3D representation without using vanishing points.The modular perspective method allows us to work in true three-dimensionality on the perspective plane (PPl). We will explain how to measure directly on the PPl the triad coordinates (x, y, p) of a given point into the visual space, and how to play with the symmetrical planes X and Y (SPl X/Y) in order to generate or recover data. Finally we will explain how to employ modular perspective in generative design formal-process through an example of application.

title A relational approach of cooperation in building design
source International conference on concurrent enterprising, Rome
summary The methods and models of the concurrent engineering taken from the industry domain are unsuitable for the domain of the construction, which is characterized by a singular context of cooperation. The existing groupware tools can not be directly used in the framework of the architectural conception. They require a high level of definition of procedures and exchanges, which is incompatible with the flexibility of current practices. At first, we present the particularity of the context of the building cooperation, then we illustrate through an experiment the problems put by the use of a groupware tool based on a hierarchical data organization. From this experiment, we justify the interest of building a new model of cooperation where the relational organization of the project is taken into account. The integration of this new dimension allows to propose to the user an adapted vision of the project by taking into account the role he plays inside the project.

title From 2D Base Map To 3D City Model
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.17-I.28
summary Since 1997 Helsinki City Survey Division has proceeded in experimenting and in developing the methods for converting and supplementing current digital 2D base maps in the scale 1:500 to a 3D city model. Actually since 1986 project areas have been produced in 3D for city planning and construction projects, but working with the whole map database started in 1997 because of customer demands and competitive 3D projects. 3D map database needs new data modelling and structures, map update processes need new working orders and the draftsmen need to learn a new profession; the 3D modeller. Laser-scanning and digital photogrammetry have been used in collecting 3D information on the map objects. During the years 1999-2000 laser-scanning experiments covering 45 km2 have been carried out utilizing the Swedish TopEye system. Simultaneous digital photography produces material for orto photo mosaics. These have been applied in mapping out dated map features and in vectorizing 3D buildings manually, semi automatically and automatically. In modelling we use TerraScan, TerraPhoto and TerraModeler sw, which are developed in Finland. The 3D city model project is at the same time partially a software development project. An accuracy and feasibility study was also completed and will be shortly presented. The three scales of 3D models are also presented in this paper. Some new 3D products and some usage of 3D city models in practice will be demonstrated in the actual presentation.

title Architectural Composition in Digital Space
source Digital Design [21th eCAADe Conference Proceedings / ISBN 0-9541183-1-6] Graz (Austria) 17-20 September 2003, pp. 587-590
summary In this paper the possibilities of using the computers at course of architectural compositions are considered. As the start point of the new teaching method of architectural composition we used the course of tradition architectural composition, elaborated at our Faculty. The course of Digital Architectural Composition was finished in 2002. The main goal of using the new digital media for modelling architectural forms was checking the new possibilities of form creation. Traditionally, searching of forms at the conceptual design stage is performed by using sketches, drawings and physical models. Our new method showed that is possible to do the same thing using the computerbased 3D modelling, experiencing no physical limitations of the 'real' substance. At the same time, at the early design stages, when formal value is sought, computer modelling can be done almost intuitively. In ours work we try to find a creative way of using computer - transforming the tool into medium. The attention was paid on exploring the possibilities characteristic for computers and not available with traditional methods of modelling. Architect’s tradition tools are effectively replaced by a computer, which create a new way of doing things.

title An Image-based and Knowledge-based System for Efficient Architectural and Urban Modeling
source Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 229-238
summary In this paper, we present two user-centered systems aiming at making easier the modeling ofarchitectural and urban scenes by using two different but complementary approaches. The first oneMArINa, an image-based modeler, allows the user to reconstruct urban scenes from one or moregraphical documents. This method focuses more on reconstructing models and is more dedicated tothe production of 3D sketches. The second modeler, MArCo is a knowledge-based modelercontaining the know-from and know-how on classical architecture. It allows the user to modelclassical architectural scenes verifying automatically all the domain rules. Finally, we show howMArINa and MArCo can cooperate providing the user a tool combining efficiently their respectivecapabilities.

title Resource-Adaptive 3D Maps for Location Based Services
source UMDS '02 Proceedings, Prague (Czech Republic) 2-4 October 2002, I.29-I.38
summary In this paper, we present a database driven approach for managing and visualizing 3D urban city models and related multimedia content. Such a 3D database is a core component of a 3D Cadastre system (Coors 2002a). In the TellMaris project (IST 2000- 28249, www.tellmaris.com), we will make use of the 3D database to generate 3D maps. The objective of TellMaris is the development of a generic 3D-map interface to tourist information on mobile computers. The interface provides a new concept for creating value added information services on mobile computers for the European citizens related to geographical information. The interface is in the project used for accessing tourist information relevant for boat tourism in the Baltic Sea and Aegean Sea area in the Mediterranean. In this paper we focus on the online generation and compression of 3D-maps in order to make use of these maps in a mobile enviroment.

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 Physical and Virtual Tools: Activity Theory Applied to the Design of Groupware
source Computer Supported Cooperative Work (CSCW), Kluwer
summary Activity theory is based on the concept of tools mediating between subjects and objects. In this theory, an individual's creative interaction with his or her surroundings can result in the production of tools. When an individual's mental processes are exteriorized in the form of tools - termed objectification - they become more accessible to other people and are therefore useful for social interaction. This paper shows how our understanding of activity theory has shaped our design philosophy for groupware and how we have applied it. Our design philosophy and practice is exemplified by a description of the BUILD-IT system. This is an Augmented Reality system we developed to enhance group work; it is a kind of graspable groupware which supports cooperative planning. The system allows a group of people, co-located around a table, to interact, by means of physical bricks, with models in a virtual three-dimensional (3D) setting. Guided by task analysis, a set of specific tools for different 3D planning and configuration tasks was implemented as part of this system. We investigate both physical and virtual tools. These tools allow users to adjust model height, viewpoint, and scale of the virtual setting. Finally, our design practice is summarized in a set of design guidelines. Based on these guidelines, we reflect on our own design practice and the usefulness of activity theory for design.

title Beyond Representation: Real Time Form Finding of Tensegrity Structures with 3d ‘Compressed’ Components
source Computation: The New Realm of Architectural Design [27th eCAADe Conference Proceedings / ISBN 978-0-9541183-8-9] Istanbul (Turkey) 16-19 September 2009, pp. 21-30
summary Tensegrity structures are of interest to architecture and engineering as a practical means to explore lightweight and rapidly deployable modular structures that have a high degree of geometric freedom and formal potency. The notion of tensegrity structures with 3D ‘compressed’ components is introduced and their feasibility is demonstrated through selected physical models. Attempts to further explore the architectural potential of tensegrity structures within a computational environment have proven difficult, as they are statically indeterminate and require form finding procedures to “find a geometry compatible with a self-stress state” (Motro 2002). An overview of tensegrity ‘capable’ software that can be used for architectural design is followed by a discussion that introduces an additional computational method based on particle-spring systems. This approach enables real time manipulation of tensegrity networks. Two projects that utilize this unique tool are described.

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.

title Definition of a Method of Limits of the Simplification of a Hall Model in a CAD System to Diminish Falsification of Acoustic Simulation Results
source Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 695-704
summary During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation. The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002). This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (Amphi- EAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.

summary In Taiwan, the National Science Council (NSC) has launched the “National Digital Archives Program” (NDAP) since 2002. We participated in two projects: “The 3D digital museum of Taiwan city and architecture” and “Digital model database and professional service for Taiwan city and architecture”. The first one attempted to build a virtual museum for Taiwan city and architecture through the past four hundred years. The second one was a value-added project which intended to further apply the digital contents of the previous one. This project was consisted of 3D refined data, digital knowledge database, and architecture professional service. We were responsible for the 3D refined data. As a result, the digital model database included three cities: Hsinchu, Chiayi, and Tainan, as well as sixty-four architecture models. The interactive entertainment platform is an important leisure in our daily life. In general, the interactive entertainment includes five types: arcade game, PC game, on-line game, TV game, and mobile entertainment. This research pays attentions to the arcade game which presents dynamic interactions between machine and users. Following the improvements of design techniques, we have opportunities to experience many arcade games with different purposes, such as drum game, dance game, and fishing simulator. However, we further apply the digital model database to create an interactive entertainment platform for a racing arcade game.

At this time, some interesting applicative results, rising from pseudo-random and l-system formalisms, came to generate complex and rather realistic immersive environments. Next step could be achieved by mixing those techniques to emerging calculus, dealing whith topographic or environmental constraints. As a matter of fact, future developments will aim to contribute to archeological or historical restitution, quickly providing credible 3D environments in a given historical context.

summary Architectural design has relevance to the design of virtual worlds that create a sense of place throughthe metaphor of buildings, rooms, and inhabitable spaces. The design and implementation of virtualworlds has focused on the design of 3D form for fast rendering to allow real time exploration of theworld. Using platforms that were originally designed for computer games, some virtual worlds nowcontain preprogrammed interactive behaviors. We present an agent model of virtual worlds in which theobjects in the world have agency, that is, the objects can sense their environment, reason about theirgoals, and make changes to the environment. This agent model is presented and illustrated using a wallagent. Following from the wall agent, we generalize how agency can be attached to any 3D model in avirtual world.

This case corresponds to the building system of Villa Victoria Cultural Center, Mar del Plata, Argentina. The building of a 3-D Digital Model implies the operations of geometric modelling by using Parametric CAD systems in this case, and to the operations of visual modelling in all respects. The analysis focused on three aspects: the morphological aspect, which comprises the visualization and the analysis of the model shapes; the constructional aspect, which deals with the component elements of the model ; and the realistic aspect, where shapes are complemented with appearence by incorporating materialization features which relate to the perception of the finished model.

title Schematic design system for flexible and multi-aspect design thinking
source Automation in Construction 11 (2) (2002) pp. 147-159
summary A designer-friendly CAD for a schematic design is one of the important topics of CAD studies. There were attractive preceding studies aiming to develop a CAD that intended to enable designers to have flexible design thinking and interactively manipulate representation models. This paper has the same goals of study, but focuses on the needs to support flexible and multi-aspect design thinking. Though designers normally hope to elaborate on their ideas using separate sets of representation models suitable for respective studies, a present CAD that is designed to build a single set 3D model, has limited its ability as a tool for a schematic design. Assuming this as the base concept, authors have studied to develop a prototype of a schematic design system, customizing AutoCAD R14J: Schematic Design System '98 (SDS'98). It has convenient utilities both for building separate sets of representation models and for integrating and reconciling those models to build a single consolidate model. This paper discusses the common procedures of schematic design studies, necessary functional features for SDS, a case study of the system use, and finally, the advantages and the disadvantages of the proposed system.

title Semi-metric formal 3D reconstruction from perspective sketches
source Proceedings of International Conference on Computational Science (ICCS), pp. 285-294, Amsterdam, The Netherlands
summary We present a new approach for accurate and fast reconstruction of 3D models from hand-drawn perspective sketches and imposed geometric constraints. A distinctive feature of the approach is the decomposition of the reconstruction process into the stages of correction of the 2D sketch and elevation of the 3D model. All 3D constraints that describe the spatial structure of the model are strictly satisfied, while preferences that describe the model projection are treated in relaxed manner. The constraints are subdivided into the projective, affine and metric ones and expressed in algebraic form by using the Grassmann-Cayley algebra. The constraints are resolved one by another following the order of their types by using the local propagation methods. The preferences allow to apply linear approximations and to systematically use formal methods.

title Architects’ Visual Literacy

summary This paper presents a partial summary of my PhD research with the working title: “View preferences and effects - a study of visual language for architectural design within a represented urban context”. In contrast to much VR-research that focuses on techniques for the public presentation of a completed design or an existing urban site, this research focuses on the use of 3D-city-models during the architectural design process. The models serve as a source of visual information that can be used to bring the design in a good relation with the yet existing built environment. In the research, I investigated the possibilities to make a VRML - city-model adaptable in its representation, in order to adhere to both the factual and the imaginative needs of a designing architect. The paper consecutively presents the problem, the conceptual change and development of research questions, the methodology and a brief overview of the research findings.
