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. Building parameters are integrated in the report to provide insight on the variations among design alternatives.

title	The use of genetic programming for applications in the field of spatial composition
source	International Conference on Generative Art
summary	Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.

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	Development of an Interactive Simulation System for Environment-Behavior Study
source	Simulation of Architectural Space - Color and Light, Methods and Effects [Proceedings of the 4rd European Architectural Endoscopy Association Conference / ISBN 3-86005-267-5] Dresden (Germany), 29 September - 1 October 1999, pp. 36-49
summary	An important recent development in the simulation techniques was the changes in the mode of presentation: from passive mode to active one. It is now possible to present an image according to the observer’s voluntary movement of body and head by means of a head-mounted display. Such interactive simulation system, which allows people to observe what they like to see, is suitable to study environmental perception, because active attention is essential to manipulate enormous information in the environment. The present paper reports two case studies in which an interactive simulation system was developed to test psychological impact of interior and exterior spaces: the case study 1 intended to clarify the effect of the disposition of transparent and opaque surfaces of a room on the occupants’ „sense of enclosure“, the case study 2 intended to make clear some physical features along a street which are influential for changing atmosphere. In addition to the empirical research, an attempt to develop a new simulation system which uses both analogue and digital images is briefly reported, and a preliminary experiment was conducted to test the performance of the simulation system in which such movable elements as pedestrians and cars generated by real-time CG were overlaid on the video image of a scale model street.

title	Use Case Driven Object Modeling with UML
source	A Practical Approach. Reading, MA: Addison-Wesley
summary	Combining some of today's best ideas about customer-driven object-oriented design, Use Case Driven Object Modeling with UML: A Practical Approach shows you how to use Unified Modeling Language (UML) in the real world, keeping with the author's proprietary software design process. The book begins with the genesis of the author's ICONIX Unified Object Modeling Approach, borrowing ideas and strategies from the "three amigos" who invented UML: Grady Booch, James Rumbaugh, and Ivar Jacobson. Throughout this text, the ICONIX method is used to model a stock trading system, with all the relevant UML diagrams, beginning with class definition and use cases. The author's approach to software relies heavily on customer requirements and use case scenarios for which he has a good deal of practical advice. He provides numerous hints for avoiding bogged-down diagrams. After preliminary design, he advocates drilling down into specifics with robustness diagrams, which trace how classes interact with one another. The most detailed design work comes next with sequence diagrams. Subsequent chapters offer tips on project management, implementation, and testing. Throughout this lively and intelligently organized book, the author presents numerous real-world tips (and Top 10 lists) that supply wisdom to his perspective on effective software design.

title	STEP and SGML/XML: what it means, how it works
source	XML Europe ‘99 Conference Proceedings, Graphic Communication Association, 1999, pp. 267-70
summary	The STEP standard, ISO 10303, is the primary standard for data representation and interchange in the product design and manufacturing world. Originally designed to enable the interchange of 3-D CAD models between different systems, like SGML, it has defined and uses a general mechanism for representing and managing complex data of any type. Increasingly products are defined as solid models that are stored in product databases. These databases are not limited to shape but contain a considerable wealth of other information, such as materials, failure modes, task descriptions, product related meta-data such as approvals and much more. The product world is of course also replete with documents, from requirements through specifications to user manuals. These documents both act as input to the product development processes and are output as well. Indeed in some cases documents form part of the product and are given part numbers. It is therefore not surprising to find that there are many companies where there are very real requirements to interact and interoperate between the product data and documents, specifically in the form of SGML-based data. This paper reports on work in progress to bring the two worlds together. This is primarily being done through the SGML and Industrial Data Preliminary Work Item under ISO TC184/SC4. The need for common capabilities for using STEP and SGML together has been obvious for a long time as can be seen from the inclusion of product data and SGML-based data within initiatives such as CALS. However, until recently, this requirement was never satisfied, for various reasons. For the last year or more, a small group has been actively pursuing this area and gaining the necessary understandings across the different standards. It is this work that is reported here. The basic thrust of the work is to answer the questions: Can STEP and SGML be used together and, if so, how?

summary	I am an architect who has the experience of using computers. A user and not an expert in digital design, therefore what follows is a foot soldier's report from my practice over the past 10 to 11 years, including the role of computers in our approach to creating architecture. I began my working life tending IBM mainframes for the British Shoe Corporation. The two IBM mainframe computers were state of the art computer technology of the mid 1970's. There were two as one was used, and the other we needed for backup. The developments in computing in terms of size, increase in storage capacity and faster processing speed over the past 30 years, is a technological acceleration which is difficult to visualize. The IBM historian in the UK suggested "that if cars had developed in the same way they would be given away free with corn flakes". A frightening thought as our cities grind under the pressure of increased car ownership. British Shoe Corporation also had a reserve system some sixty miles away and a halon extinguishing system in case of fire - such was the capital and commercial value of the system. We carried out transitional computing for a number of European countries. The CAD was limited - pen potters drawing shoes, drawing them less well than an average A level or high school student! My interest was primarily in art and not computers; my aim to earn enough to tour Europe to see key work 'in the flesh' not just in reproduction.

summary	In 1998, thanks to the support of the Program to Enhance Scholarly and Creative Activities of Texas A&M University, the author was able to establish a digital research network that promotes and coordinates collaborative research and development projects at inter-continental level. The original objective was to establish a network of 5 schools of Architecture. This objective was largely surpassed. At the time of editing this paper, the Las Américas Digital Research Network brings together 17 schools of Architecture (from Canada to Argentina). See http://taz.tamu.edu/~americas/ In this collaborative framework, we have been able to identify a number of research and development opportunities. This paper reports on some of the on-going initiatives of the network, namely: a) The Las Americas Virtual Design Studio, b) The Las Americas Virtual Gallery of Visual Arts, c) The Las Americas Research Journal "Archi-Forum" and, d) The Las Americas Curriculum Harmonization Initiative. In addition to a report on current activities, this paper aims to promote new initiatives and identify potential sources of research & development funding. The paper ends with conclusions and a call for widespread participation.

summary	"Space," which has long been an important concept in architecture (Bloomer & Moore, 1977; Mitchell, 1995, 1999), has attracted interest of researchers from various academic disciplines in recent years (Agnew, 1993; Benko & Strohmayer, 1996; Chang, 1999; Foucault, 1982; Gould, 1998). Researchers from disciplines such as anthropology, geography, sociology, philosophy, and linguistics regard it as the basis of the discussion of various theories in social sciences and humanities (Chen, 1999). On the other hand, since the invention of Internet, Internet users have been experiencing a new and magic "world." According to the definitions in traditional architecture theories, "space" is generated whenever people define a finite void by some physical elements (Zevi, 1985). However, although Internet is a virtual, immense, invisible and intangible world, navigating in it, we can still sense the very presence of ourselves and others in a wonderland. This sense could be testified by our naming of Internet as Cyberspace -- an exotic kind of space. Therefore, as people nowadays rely more and more on the Internet in their daily life, and as more and more architectural scholars and designers begin to invest their efforts in the design of virtual places online (e.g., Maher, 1999; Li & Maher, 2000), we cannot help but ask whether there are indeed sensible spaces in Internet. And if yes, these spaces exist in terms of what forms and created by what ways?To join the current interdisciplinary discussion on the issue of space, and to obtain new definition as well as insightful understanding of "space", this study explores the spatial phenomena in Internet. We hope that our findings would ultimately be also useful for contemporary architectural designers and scholars in their designs in the real world.As a preliminary exploration, the main objective of this study is to discover the elements involved in the creation/construction of Internet spaces and to examine the relationship between human participants and Internet spaces. In addition, this study also attempts to investigate whether participants from different academic disciplines define or experience Internet spaces in different ways, and to find what spatial elements of Internet they emphasize the most.In order to achieve a more comprehensive understanding of the spatial phenomena in Internet and to overcome the subjectivity of the members of the research team, the research design of this study was divided into two stages. At the first stage, we conducted literature review to study existing theories of space (which are based on observations and investigations of the physical world). At the second stage of this study, we recruited 8 Internet regular users to approach this topic from different point of views, and to see whether people with different academic training would define and experience Internet spaces differently.The results of this study reveal that the relationship between human participants and Internet spaces is different from that between human participants and physical spaces. In the physical world, physical elements of space must be established first; it then begins to be regarded as a place after interaction between/among human participants or interaction between human participants and the physical environment. In contrast, in Internet, a sense of place is first created through human interactions (or activities), Internet participants then begin to sense the existence of a space. Therefore, it seems that, among the many spatial elements of Internet we found, "interaction/reciprocity" Ñ either between/among human participants or between human participants and the computer interface Ð seems to be the most crucial element.In addition, another interesting result of this study is that verbal (linguistic) elements could provoke a sense of space in a degree higher than 2D visual representation and no less than 3D visual simulations. Nevertheless, verbal and 3D visual elements seem to work in different ways in terms of cognitive behaviors: Verbal elements provoke visual imagery and other sensory perceptions by "imagining" and then excite personal experiences of space; visual elements, on the other hand, provoke and excite visual experiences of space directly by "mapping".Finally, it was found that participants with different academic training did experience and define space differently. For example, when experiencing and analyzing Internet spaces, architecture designers, the creators of the physical world, emphasize the design of circulation and orientation, while participants with linguistics training focus more on subtle language usage. Visual designers tend to analyze the graphical elements of virtual spaces based on traditional painting theories; industrial designers, on the other hand, tend to treat these spaces as industrial products, emphasizing concept of user-center and the control of the computer interface.The findings of this study seem to add new information to our understanding of virtual space. It would be interesting for future studies to investigate how this information influences architectural designers in their real-world practices in this digital age. In addition, to obtain a fuller picture of Internet space, further research is needed to study the same issue by examining more Internet participants who have no formal linguistics and graphical training.

summary	The study of a cyberuniversity derives from an analogy between real urban space and its virtual "substitution". It represents an attempt to balance some views, which seems to be contrary, exclusive, but they are just parts of the same wholeness. Especially the notion of a cyber society is lately considered such an exaggeration, that it is possible to forget the meaning of a real life experience and interactions, which are already threatened. One should contribute to the awarness that is used in such a comparison, it is "just" an analogy, not a real similarity. At the same time it is possible to point out some limitations of a cyberspace and indicate a more realistic view of the meaning of cyber communities. Awarness of the development processes could help to find a balance between reality and virtuality, using cyberfacilities not to destroy us (our identity) but to improve the quality of our (real) life.

summary	How and when should CAAD be introduced in the curriculum of the School of Architecture? This paper begins with some arguments for starting CAAD education at the very beginning. At the School of Architecture in Lund teachers in the first year courses have tried to integrate CAAD with the introduction to architectural concepts and techniques. Traditionally the first year is divided by several subjects running courses separatly without any contact for coordination. From the academic year 96/97 the teachers of Aplied aestetics, Building Science, Architectural design and CAAD have decided to colaborate as much as possible to make the role of our different fields as clear as possible to the students. Therefore integrating CAAD was a natural step in the academic year 98/99. The computer techniques were taught one step in advance so that the students can practise their understanding of the programs in their tasks in the other subjects. The results were surprisingly good! The students have quickly learned to mix the manual and computer techniques to make expressive and interesting visual presentations of their ideas. Some students with antipaty to computers have overcome this handicap. Some interesting observations are discussed.

source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 519-525
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	The Art of Emergence
source	International Conference on Generative Art
summary	Since several years, the term emergence is mentioned in the paradigm of chaos and complexity. Following this approach, complex system constituted by multitude of individual develop global behavioral properties on the base of local chaotic interactions (self-organization). These theories, developed in scientific and philosophical milieus are rapidly spreading as a "way of thinking" in the several fields of cognitive activities. According to this "way of thinking" it is possible revise some fundamental themes as the economic systems, the cultural systems, the scientific paths, the communication nets under a new approach where nothing is pre-determined, but the global evolution is determined by specific mechanisms of interaction and fundamental events (bifurcation). With a jump in scale of the life, also other basic concepts related to the individuals as intelligence, consciousness, psyche can be revised as self-organizing phenomena. Such a conceptual fertility has been the base for the revision of the artistic activities as flexible instruments for the investigation of imaginary worlds, metaphor of related real worlds. In this sense we claim to the artist a role of "researcher". Through the free exploration of new concepts, he can evoke qualities, configurations and hypothesis which have an esthetical and expressive value and in the most significant cases, they can induce nucleation of cultural and scientific bifurcation. Our vision of the art-science relation is of cooperative type instead of the conflict of the past decades. In this paper we describe some of the most significant realized artworks in order to make explicit the concepts and basic themes. One of the fundamental topics is the way to generate and think to the artwork. Our characterization is to see the artwork not as a static finished product, but as an instance or a dynamic sequence of instances of a creative process which continuously evolves. In this sense, the attention is focused on the "generative idea" which constitutes the envelop of the artworks generable by the process. In this approach the role of technology (computers, synthesizers) is fundamental to create the dimension of the generative environment. Another characterizing aspect of our artworks is derived by the previous approach and specifically related to the interactive installations. The classical relation between artist, artwork and observers is viewed as an unidirectional flux of messages from the artist to the observer through the artwork. In our approach artist, artwork and observer are autonomous entities provided with own personality which jointly intervene to determine the creative paths. The artist which generate the environment in not longer the "owner" of the artwork; simply he dialectically bring the generative environment (provided by a certain degree of autonomy) towards cultural and creative "void" spaces (not still discovered). The observers start from these platforms to generate other creative paths, sometimes absolutely unexpected , developing their new dialectical relations with the artwork itself. The results derived by these positions characterize the expressive elements of the artworks (images, sequences and sounds) as the outcomes of emergent behavior or dynamics both in the sense of esthetical shapes emergent from fertile generative environments, either in terms of emergent relations between artist, artwork and observer, either in terms of concepts which emerge by the metaphor of artificial worlds to produce imaginary hypothesis for the real worlds.

title	Let's Improvise Together
source	International Conference on Generative Art
summary	The creators of ‘Let's-Improvise-Together’ adhere to the idea that while there is a multitude of online games now available in cyberspace, it appears that relatively few are focused on providing a positive, friendly and productive experience for the user. Producing this kind of experience is one the goals of our Amusement Project.To this end, the creation of ‘Let's Improvise Together’ has been guided by dedication to the importance of three themes:* the importance of cooperation,* the importance of creativity, and* the importance of emotion.Description of the GameThe avatar arrives in a certain area where there are many sound-blocks/objects. Or he may add sound "property" to existing ones. He can add new objects at will. Each object may represents a different sound, they do not have to though. The avatar walks around and chooses which objects he likes. Makes copies of these and add sounds or change the sounds on existing ones, then with all of the sound-blocks combined make his personalized "instrument". Now any player can make sounds on the instrument by approaching or bumping into a sound-block. The way that the avatar makes sounds on the instrument can vary. At the end of the improvising session, the ‘composition’ will be saved on the instrument site, along with the personalized instrument. In this way, each user of the Amusement Center will leave behind him a unique instrumental creation, that others who visit the Center later will be able to play on and listen to. The fully creative experience of making a new instrument can be obtained connecting to Active Worlds world ‘Amuse’ and ‘Amuse2’.Animated colorful sounding objects can be assembled by the user in the Virtual Environment as a sort of sounding instrument. We refrain here deliberately from using the word musical instrument, because the level of control we have on the sound in terms of rythm and melody, among other parameters, is very limited. It resembles instead, very closely, to the primitive instruments used by humans in some civilizations or to the experience made by children making sound out of ordinary objects. The dimension of cooperation is of paramount importance in the process of building and using the virtual sounding instrument. The instrument can be built on ones own effort but preferably by a team of cooperating users. The cooperation has as an important corolary: the sharing of the experience. The shared experience finds its permanence in the collective memory of the sounding instruments built. The sounding instrument can be seen also as a virtual sculpture, indeed this sculpture is a multimedial one. The objects have properties that ranges from video animation to sound to virtual physical properties like solidity. The role of the user representation in the Virtual World, called avatar, is important because it conveys, among other things, the user’s emotions. It is worth pointing out that the Avatar has no emotions on its own but it simply expresses the emotions of the user behind it. In a way it could be considered a sort of actor performing the script that the user gives it in real-time while playing.The other important element of the integration is related to the memory of the experience left by the user into the Virtual World. The new layout is explored and experienced. The layout is a permanent editable memory. The generative aspects of Let's improvise together are the following.The multi-media virtual sculpture left behind any participating avatar is not the creation of a single author/artist. The outcome of the sinergic interaction of various authors is not deterministic, nor predictable. The authors can indeed use generative algorythm in order to create the texture to be used on the objects. Usually, in our experience, the visitors of the Amuse worlds use shareware programs in order to generate their texture. In most cases the shareware programs are simple fractals generators. In principle, it is possible to generate also the shape of the object in a generative way. Taking into account the usual audience of our world, we expected visitors to use very simple algorythm that could generate shapes as .rwx files. Indeed, noone has attempted to do so insofar. As far as the music is concerned, the availability of shareware programs that allow simple generation of sounds sequences has made possible, for some users, to generate sounds sequences to be put in our world. In conclusion, the Let's improvise section of the Amuse worlds could be open for experimentation on generative art as a very simple entry point platform. We will be very happy to help anybody that for educational purposes would try to use our platform in order to create and exhibit generative forms of art.

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	Sistemas multimediales aplicados a la arquitectura y su conocimiento (Multimedia Systems Applied to Architecture and its Knowledge Base)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 186-191
summary	This text makes a careful description of a great part of the components of the vocabulary of architecture and their syntax. It's structured in two parts, one textual and the other graphic. Due to the acknowledged contribution of the author on the subject of description of vocabulary of the elements of architecture and the research and development works that are entered upon in the master in computer graphics in the informatic field, it was proposed the development of an interactive system that allowed by means of links to connect the different parts of text and their respective graphics. Having as a basis the idiomatic equivalent term in Spanish and English, carried out in another research work, it was considered the possibility to link the text in these two languages besides the original one, french. That's why we've decided to propose the navigation through numeric text and images. This navigation has been already inferred from the reading of the text as intended from the author's that was why our task has been the interpretation of this intention and its translation in an informatic system. The product presented in this work is limited to having designed a methodology and showing its performance with some terms and images, able to make evident the sketch of our idea. The work is made out of the description of the following phases: 1.) Design of its interface; 2.) Compilation and classification of images compilation and classification of text; 3.) Coordination of textual and graphic elements; 4.) Programming of events in the interactive system.

title	Posicionamiento de Volúmenes Arquitectónicos Mediante Algoritmos Evolucionistas (Positioning of Architectural Volumes by Means of Evolutionist Algorithms)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 176-181
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.

title	VDU WORK IN DIFFERENT LIGHTING CONDITIONS
source	Full-scale Modeling and the Simulation of Light [Proceedings of the 7th European Full-scale Modeling Association Conference / ISBN 3-85437-167-5] Florence (Italy) 18-20 February 1999, pp. 7-28
summary	In order to avoid the disadvantages of purely subjective methods in a technical evaluation of daylight and artificial light systems, the Bartenbach LichtLabor developed new test methods which can determine objectively and quantitatively the visual or psycho-physiological stress connected with VDU work [1], depending on different lighting conditions. Daylight and artificial lighting systems were tested with these methods and compared by using the performances achieved by the test subjects. Some highly significant differences in performance done under the individual lighting systems became apparent and demonstrated that the visual stress or the physical or physiological fatigue from an ergonomic viewpoint depends largely on the lighting conditions at the workplace. This holds true for daylight systems (glare protection, re-directing lamellae, clear window as a control condition) as well as for purely artificial lighting systems where especially the choice of color temperature of the light and the used control gear (conventional or electronic) determine the resulting performance. Optimized lighting also positively affects the productivity and economicy for the design of workplaces that take the human factor into account.

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.
