summary	Years of trying to create an "Image Idea Generator" program have convinced me that the perfect solution would be to have an artificial artistic person, a design slave. This paper describes how I came to that conclusion, realistic alternatives, and briefly, how it could possibly happen. 1. The history of Repligator and Gliftic 1.1 Repligator In 1996 I had the idea of creating an “image idea generator”. I wanted something which would create images out of nothing, but guided by the user. The biggest conceptual problem I had was “out of nothing”. What does that mean? So I put aside that problem and forced the user to give the program a starting image. This program eventually turned into Repligator, commercially described as an “easy to use graphical effects program”, but actually, to my mind, an Image Idea Generator. The first release came out in October 1997. In December 1998 I described Repligator V4 [1] and how I thought it could be developed away from simply being an effects program. In July 1999 Repligator V4 won the Shareware Industry Awards Foundation prize for "Best Graphics Program of 1999". Prize winners are never told why they won, but I am sure that it was because of two things: 1) Easy of use 2) Ease of experimentation "Ease of experimentation" means that Repligator does in fact come up with new graphics ideas. Once you have input your original image you can generate new versions of that image simply by pushing a single key. Repligator is currently at version 6, but, apart from adding many new effects and a few new features, is basically the same program as version 4. Following on from the ideas in [1] I started to develop Gliftic, which is closer to my original thoughts of an image idea generator which "starts from nothing". The Gliftic model of images was that they are composed of three components: 1. Layout or form, for example the outline of a mandala is a form. 2. Color scheme, for example colors selected from autumn leaves from an oak tree. 3. Interpretation, for example Van Gogh would paint a mandala with oak tree colors in a different way to Andy Warhol. There is a Van Gogh interpretation and an Andy Warhol interpretation. Further I wanted to be able to genetically breed images, for example crossing two layouts to produce a child layout. And the same with interpretations and color schemes. If I could achieve this then the program would be very powerful. 1.2 Getting to Gliftic Programming has an amazing way of crystalising ideas. If you want to put an idea into practice via a computer program you really have to understand the idea not only globally, but just as importantly, in detail. You have to make hard design decisions, there can be no vagueness, and so implementing what I had decribed above turned out to be a considerable challenge. I soon found out that the hardest thing to do would be the breeding of forms. What are the "genes" of a form? What are the genes of a circle, say, and how do they compare to the genes of the outline of the UK? I wanted the genotype representation (inside the computer program's data) to be directly linked to the phenotype representation (on the computer screen). This seemed to be the best way of making sure that bred-forms would bare some visual relationship to their parents. I also wanted symmetry to be preserved. For example if two symmetrical objects were bred then their children should be symmetrical. I decided to represent shapes as simply closed polygonal shapes, and the "genes" of these shapes were simply the list of points defining the polygon. Thus a circle would have to be represented by a regular polygon of, say, 100 sides. The outline of the UK could easily be represented as a list of points every 10 Kilometers along the coast line. Now for the important question: what do you get when you cross a circle with the outline of the UK? I tried various ways of combining the "genes" (i.e. coordinates) of the shapes, but none of them really ended up producing interesting shapes. And of the methods I used, many of them, applied over several "generations" simply resulted in amorphous blobs, with no distinct family characteristics. Or rather maybe I should say that no single method of breeding shapes gave decent results for all types of images. Figure 1 shows an example of breeding a mandala with 6 regular polygons: Figure 1 Mandala bred with array of regular polygons I did not try out all my ideas, and maybe in the future I will return to the problem, but it was clear to me that it is a non-trivial problem. And if the breeding of shapes is a non-trivial problem, then what about the breeding of interpretations? I abandoned the genetic (breeding) model of generating designs but retained the idea of the three components (form, color scheme, interpretation). 1.3 Gliftic today Gliftic Version 1.0 was released in May 2000. It allows the user to change a form, a color scheme and an interpretation. The user can experiment with combining different components together and can thus home in on an personally pleasing image. Just as in Repligator, pushing the F7 key make the program choose all the options. Unlike Repligator however the user can also easily experiment with the form (only) by pushing F4, the color scheme (only) by pushing F5 and the interpretation (only) by pushing F6. Figures 2, 3 and 4 show some example images created by Gliftic. Figure 2 Mandala interpreted with arabesques Figure 3 Trellis interpreted with "graphic ivy" Figure 4 Regular dots interpreted as "sparks" 1.4 Forms in Gliftic V1 Forms are simply collections of graphics primitives (points, lines, ellipses and polygons). The program generates these collections according to the user's instructions. Currently the forms are: Mandala, Regular Polygon, Random Dots, Random Sticks, Random Shapes, Grid Of Polygons, Trellis, Flying Leap, Sticks And Waves, Spoked Wheel, Biological Growth, Chequer Squares, Regular Dots, Single Line, Paisley, Random Circles, Chevrons. 1.5 Color Schemes in Gliftic V1 When combining a form with an interpretation (described later) the program needs to know what colors it can use. The range of colors is called a color scheme. Gliftic has three color scheme types: 1. Random colors: Colors for the various parts of the image are chosen purely at random. 2. Hue Saturation Value (HSV) colors: The user can choose the main hue (e.g. red or yellow), the saturation (purity) of the color scheme and the value (brightness/darkness) . The user also has to choose how much variation is allowed in the color scheme. A wide variation allows the various colors of the final image to depart a long way from the HSV settings. A smaller variation results in the final image using almost a single color. 3. Colors chosen from an image: The user can choose an image (for example a JPG file of a famous painting, or a digital photograph he took while on holiday in Greece) and Gliftic will select colors from that image. Only colors from the selected image will appear in the output image. 1.6 Interpretations in Gliftic V1 Interpretation in Gliftic is best decribed with a few examples. A pure geometric line could be interpreted as: 1) the branch of a tree 2) a long thin arabesque 3) a sequence of disks 4) a chain, 5) a row of diamonds. An pure geometric ellipse could be interpreted as 1) a lake, 2) a planet, 3) an eye. Gliftic V1 has the following interpretations: Standard, Circles, Flying Leap, Graphic Ivy, Diamond Bar, Sparkz, Ess Disk, Ribbons, George Haite, Arabesque, ZigZag. 1.7 Applications of Gliftic Currently Gliftic is mostly used for creating WEB graphics, often backgrounds as it has an option to enable "tiling" of the generated images. There is also a possibility that it will be used in the custom textile business sometime within the next year or two. The real application of Gliftic is that of generating new graphics ideas, and I suspect that, like Repligator, many users will only understand this later. 2. The future of Gliftic, 3 possibilties Completing Gliftic V1 gave me the experience to understand what problems and opportunities there will be in future development of the program. Here I divide my many ideas into three oversimplified possibilities, and the real result may be a mix of two or all three of them. 2.1 Continue the current development "linearly" Gliftic could grow simply by the addition of more forms and interpretations. In fact I am sure that initially it will grow like this. However this limits the possibilities to what is inside the program itself. These limits can be mitigated by allowing the user to add forms (as vector files). The user can already add color schemes (as images). The biggest problem with leaving the program in its current state is that there is no easy way to add interpretations. 2.2 Allow the artist to program Gliftic It would be interesting to add a language to Gliftic which allows the user to program his own form generators and interpreters. In this way Gliftic becomes a "platform" for the development of dynamic graphics styles by the artist. The advantage of not having to deal with the complexities of Windows programming could attract the more adventurous artists and designers. The choice of programming language of course needs to take into account the fact that the "programmer" is probably not be an expert computer scientist. I have seen how LISP (an not exactly easy artificial intelligence language) has become very popular among non programming users of AutoCAD. If, to complete a job which you do manually and repeatedly, you can write a LISP macro of only 5 lines, then you may be tempted to learn enough LISP to write those 5 lines. Imagine also the ability to publish (and/or sell) "style generators". An artist could develop a particular interpretation function, it creates images of a given character which others find appealing. The interpretation (which runs inside Gliftic as a routine) could be offered to interior designers (for example) to unify carpets, wallpaper, furniture coverings for single projects. As Adrian Ward [3] says on his WEB site: "Programming is no less an artform than painting is a technical process." Learning a computer language to create a single image is overkill and impractical. Learning a computer language to create your own artistic style which generates an infinite series of images in that style may well be attractive. 2.3 Add an artificial conciousness to Gliftic This is a wild science fiction idea which comes into my head regularly. Gliftic manages to surprise the users with the images it makes, but, currently, is limited by what gets programmed into it or by pure chance. How about adding a real artifical conciousness to the program? Creating an intelligent artificial designer? According to Igor Aleksander [1] conciousness is required for programs (computers) to really become usefully intelligent. Aleksander thinks that "the line has been drawn under the philosophical discussion of conciousness, and the way is open to sound scientific investigation". Without going into the details, and with great over-simplification, there are roughly two sorts of artificial intelligence: 1) Programmed intelligence, where, to all intents and purposes, the programmer is the "intelligence". The program may perform well (but often, in practice, doesn't) and any learning which is done is simply statistical and pre-programmed. There is no way that this type of program could become concious. 2) Neural network intelligence, where the programs are based roughly on a simple model of the brain, and the network learns how to do specific tasks. It is this sort of program which, according to Aleksander, could, in the future, become concious, and thus usefully intelligent. What could the advantages of an artificial artist be? 1) There would be no need for programming. Presumbably the human artist would dialog with the artificial artist, directing its development. 2) The artificial artist could be used as an apprentice, doing the "drudge" work of art, which needs intelligence, but is, anyway, monotonous for the human artist. 3) The human artist imagines "concepts", the artificial artist makes them concrete. 4) An concious artificial artist may come up with ideas of its own. Is this science fiction? Arthur C. Clarke's 1st Law: "If a famous scientist says that something can be done, then he is in all probability correct. If a famous scientist says that something cannot be done, then he is in all probability wrong". Arthur C Clarke's 2nd Law: "Only by trying to go beyond the current limits can you find out what the real limits are." One of Bertrand Russell's 10 commandments: "Do not fear to be eccentric in opinion, for every opinion now accepted was once eccentric" 3. References 1. "From Ramon Llull to Image Idea Generation".

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.

summary	The virtual design studio (VDS) points to a new way of practicing and teaching architectural design. As a new phenomenon, little research has been done to evaluate design collaboration and multimedia usage in a distributed workplace like the virtual design studio. Our research provides empirical data on how students actually use multiple media during architectural collaborative design.

title	A topology construction from line drawings using a uniform plane subdivision technique
source	Computer-Aided Design, Vol. 31 (5) (1999) pp. 335-348
summary	The paper describes an algorithm for constructing the topology from a set of line segments or polylines. The problem appears for example at land-maps that have been drawnby general-purpose drawing packages or captured from blue-prints by digitalisation. The solution comprises two steps; in the first step inconsistencies in the input data aredetected and removed, and in the second step the topology is constructed. The algorithm for topology construction consists of two phases: determination of a concave hull,and generation of polygons. It is shown that the running-time of the presented algorithm is better than O(n2), where n is the number of input points. Because of a largenumber of geometric elements being expected, the geometric search needed at the first step of the algorithm is speeded up by an acceleration techniquea uniform planesubdivision.

title	CAD Interfaces to the ARROW Manufactured Product Server
source	Proceedings of the Eighth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-8536-5] Atlanta, 7-8 June 1999, pp. 1-11
summary	The UK national project ARROW (Advanced Reusable Reliable Objects Warehouse) provides an Internet based framework through which it is possible to identify any of a range of manufactured products meeting specific design criteria. This open framework (based upon the IAI's IFCs) provides a mechanism for users to search for products from any participating manufacturer or supplier based both on specific attributes of a product or on any of the textual descriptions of the product. The service returns the closest matching products and allows the user to navigate to related information including manufacturer, suppliers, CAD details, VR displays, installation instructions, certificates, health and safety information, promotional information, costings, etc. ARROW also provides a toolkit to enable manufacturers and suppliers to more easily map and publish their information in the format utilised by the ARROW system. As part of the ARROW project we have examined the ability to interface from a design tool through to ARROW to automatically retrieve information required by the tool. This paper describes the API developed to allow CAD and simulation tools to communicate directly with ARROW and identify appropriate manufactured information. The demonstration system enables CAD systems to identify the closest matching manufactured product to a designed product and replacing the designed product with the details supplied by the manufacturer for the manufactured product as well as pulling through product attributes utilised by the design application. This paper provides a description of the ARROW framework and issues faced in providing information based upon standards as well as containing information not currently modelled in public standards. The paper looks at issues of enabling manufacturers and suppliers to move from their current world-view of product information to a more data-rich and user accessible information repository (even though this enables a uniform comparison across a range of manufacturer's products). Finally the paper comments on the likely way forward for ARROW like systems in providing quality information to end users.

title	Space Syntax and the New Transportation System in the Santa Catarina Island
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 434-437
summary	The paper reports an on-going research that aims at describing and analysing some of the syntactic characteristics of the urban space of Santa Catarina Island, in an attempt to evaluate its performance, more specifically its social and spatial integration and segregation. The research has been conducted with the aid of the Aximagic software, still in exam stage and not yet released to the public, a tool being developed by a group of researches of the Rio Grande do Sul Federal University and given up by Prof. Doctor Benamy Turkienicz. The software is part of a larger georeferenced program called CityZoom wich includes others tools to the comprehention of the urban morphology. This program works with graphic pictures in the inlet of data and also in the acquisition of results. The syntactic study of the Santa Catarina Island as a whole aims to obtain the comprehension of its global structure, relating it to the integrated public transportation system proposed to Florianópolis. These studies should allow an understanding of the impact the developments will have upon the urban morphology, and the new public transportation system.

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	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	Infographic: Its Incorporation and Relativity in Architectural Design Process
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 313-318
summary	This paper is about an architectural design workshop regularly held at a public university in Santa Fe, Argentina. The class is about 150 students large, with different informatic capabilities and hardware facilities. The design problem of the workshop, which is one year long, is the relationship between architectural project and the construction of the urbanity. This implies both a physical intervention and a cultural expression. Pedagogy seeks students to overcome individualism, characteristic that is hardly induced by PCs, making a socialized design experience. A complementary and simultaneous use of graphic and infographic data is one of the main criteria of the workshop. The idea is to look for students to reach a wide vision by means of the use of different representation systems and means of information. Digital graphic is introduced early in the design process as an electronic model of urban context. It is considered as a one among many other graphic resources and is used together with ordinary models, geometric drawings, aerial and regular photography and hand made sketches. This paper relates the results that have been obtained when students were asked to make an analytic and sensitive approach to the relationship site - urban situation. This relationship has a great importance for the workshop since its goal is to make students to understand the the value of designing in and for the city.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 182-185
summary	The modelization of an architectural fact, generated through a CAD program, doesn't have only the purpose of generating a virtual electronic, but a constructive scale model of geometric nature. It also implies, a conceptualization level and a posture in front of the pattern that makes thinking in other fields besides the formally constructive, such as: the descriptive and geometric patterns, the communicational and the symbolic pattern. We should understand the way the constructive thought is done the message of the model, either for the relationship with the environment and with the human scale, depends not only upon the author, but his elections will be intrinsically related with his cultural baggage, besides its geometric, graphical and technicians data. These databases condition the result of the model, for this reason we analyzed these relationships looking for a good handling of the cultural codes, to achieve a complete communication of the model. In these moments of the "global village", we should consider this problematic as a visceral topic of the architectural representation, to achieve an effective communication, among different cultures, of the models represented.

title	The Use of Renewable Resource in Architecture: New Teaching Methodologies
doi	https://doi.org/10.52842/conf.ecaade.1999.751
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 751-756
summary	The program is organized into four parts. Each is very much connected, both logically and methodologically, so that the unit as a whole consists of a content and method of access that are not divided up. This method is not in a chronological order that simply goes in one direction, rather it allows the user to "refer back", in real time and in different directions. For the simple purpose of explanation, the sections of the program are listed as follows: (-) "Basic information" concerns the basics of bioclimatic and timber architecture. Without this knowledge, the other two sections would be difficult to understand; (-) "Actual buildings throughout the world"; give examples of architectural quality; they concretize the basics of bioclimatic and timber architecture; (-) "Students' Masters Theses", that follow on from the basic information and the learning experience "in the field", and guided by the lecturer, have a critical approach to actual buildings throughout the world. (-) A multimedia data-sheet organized to ensure a clear and straightforward presentation of information about the construction products. It relies on a tab-based navigation interface that gives users access to eight different stacked windows.

summary	In 1998 I undertook an inquiry into the use of information technology in Urban Design and Planning in Danish municipalities and among planning consultants. The aim was to find out who was working with the IT and for what purposes it was used. In education there seems to be barriers to a full integration of the new media, and I wanted to find out if that was also the case in the practise of architects and planners. Surprisingly I discovered that there was a computer on almost every desk, - but there were big differences in the use of the technology. The investigation described here is based on interviews with planners in selected municipalities and with urban planning consultants, and the results have been summarised in a publication.

summary	Our paper presents recent developments of a co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France), specialised in computer science and the HAiKZ Institute of Krakow's Faculty of Architecture, specialised in architectural heritage and conservation. Before undertaking any action to a listed building or interventions in its neighbourhood, it is vital to gain a clear understanding of the building in question. Numerous heterogeneous data detained by diverse institutions has to be handled. This process can be greatly eased by enhanced classification of the information. The development we present is a multidisciplinary platform independent information tool dedicated to education and research. SOL uses an http protocol centred computer architecture connecting a relational database, a VRML 2.0 representation module and a web search interface. It allows searches and updating of the database through a standard text based interface, a VRML 2.0 graphical module and a thematic interface. SOL is experienced on the urban fabric of the Main Square (Rynek Gówny) in Kraków. The choice of a web-centred development, both in the search and updating interface and in the representation module provides platform independence and distant access to the database, and enables successive contributions of students or researchers.

title	Towards Virtual Maps: On the Production of 3D City Models
source	GeoInformatics 2(5), pp. 10–13
summary	The growing demand for detailed city models has stimulated research on efficient 3D data acquisition. Over the past years, it has become evident that the automatic reconstruction of urban scenes is most promising if different types of data, possibly originating from different data sources are combined. In the approach presented in this paper the geometric reconstruction of urban areas is based on height data from airborne laser scanning and 2D GIS, which provides the ground plan geometry of buildings. Both data sources are used to estimate the type and parameter of basic primitives which in turn are combined to obtain complex building structures. The final output consists of 3D CAD models for the buildings. Using the reconstructed geometry, terrestrial images are mapped onto building facades to generate virtual city models.

title	Documentation and Patrimony. The Digital Era: A Channel for Memory Recovery
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 451-457
summary	The end of the millennium with its new digital technology is contributing important tools to the area of documentation and historical patrimony those of us who support the preservation of memories think that a very important way of personalizing and strengthening our identity is to provide to those who inhabit the city with heightened awareness towards the values of our past. The revitalization requires that the patrimony in itself be valued. At the same time, it necessitates the preparation of a great amount of information utilizing cataloguing, research databases, and other materials be accessible to all citizens. This piece of work shares the different digital data base experiences that are being developed in the CEDODAL foundation art and latinamerican architecture (center for documentation), which is under the direction of the architect Ramon Gutierrez, a research services organization, and diverse higher education institutions (universities). Four bases are introduced, each with different thought and criterion structures in the definition of fields as well as in their dynamic visualizations. Each of them possesses great quantities of digital images, blue prints, and texts. In three of those bases, the data is the output from teams of researchers in different topics through special arrangements with Santa Fe's provincial water), Fonart, and city government. At the same time, the CEDODAL catalogues its documentaries with great quantities of photographic information, blue prints, research passages, and a library.

title	Parametric Urbanism: Explorations in Generative Urban Design
source	International Conference on Generative Art
summary	This paper is the result of several years of research by the Authors into the new field of generative design, as applied to urbanism. Its purpose is to formulate a concept of parametric urbanism and data-driven urban design, and how it departs from existing concepts of urban analysis and resulting design methods. This paper first gives a definition and description of the notion of generative urban design, and its relevance to current the practice of architecture and global political, sociological and economic developments. The difference between dogmatic forms of urban design and new parametric research methods is explained, and the Authors argue the fundamental relevance of using examples of post-colonial large-scale projects. In support of this, the Authors explore the widening field of research into parametric and data-driven architecture and urban design and the history of rule-based and evolutionary design methodologies. The paper illustrates examples of successful research in the field of parametric and rule-based urban design, by the Authors as well as colleagues within the field. It surveys the Authors’ work done at the Architectural Association School of Architecture, at the Hong Kong Polytechnic University School of Design, as well as in practice and research-oriented consultancy. The projects illustrated support the thesis of parametric urbanism by showing its power and versatility when applied to very large-scale projects, in particular within the People’s Republic of China.

summary	Our collective concept of computing and its relevance to architecture has undergone dramatic shifts in emphasis. A review of popular texts from the past reveals the biases and emphases that were current. In the seventies, architectural computing was generally seen as an elective for data processing specialists. In the early eighties, personal computers and commercial CAD systems were widely adopted. Architectural computing diverged from the "batch" world into the "interactive" world. As personal computing matured, introductory architectural computing courses turned away from a foundation in programming toward instruction in CAD software. By the late eighties, Graphic User Interfaces and windowing operating systems had appeared, leading to a profusion of architecturally relevant applications that needed to be addressed in introductory computing. The introduction of desktop 3D modeling in the early nineties led to increased emphasis upon rendering and animation. The past few years have added new emphases, particularly in the area of network communications, the World Wide Web and Virtual Design Studios. On the horizon are topics of electronic commerce and knowledge markets. This paper reviews these past and current trends and presents an outline for an introductory computing course that is relevant to the year 2000.

title	Visualizacao de Informacoes Urbanas atraves de Multimidia (Visualization of Urban Information by Means of Multimedia)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 239-243
summary	Visualization is a tool that can aid understanding of phenomenon, process and spatial structures. Another important function is communication, in urban applications case, between planners, technicians, administrators, researchers and citizens. Recent technological development applied to visualization area increments analyze and interpretation capacity. The word visualization used here, is related with the use of computation for data exploration in a visual form, helping comprehension. It is a process of transformation of raw data in images, in information and visual communication. GIS and cartography precede computers. In it development GIS benefited from information technologies development and in this process emphasis goes from treatment of great amount of data to analyze of that data. Computer graphics make possible process and present visually great volume of data, thing that was not possible by conventional methods. Digital data are the key for the plain utilization of potential already available with geoprocessing technologies. Information that interest urban planners came from several sources and information technologies beside integration and manipulation permit visual analyze of spatial data in diverse aspects, from witch the most evident but not less effective a map, tool that let us correlate a great variety of qualitative and quantitative data, for organization, interpretation, presentation and communication. In digital cartographic basic elements of cartographic science were preserved, but through new products, each one execute one of the roles that traditional map plays in different ways. Database replace paper map as way of geographical information storage and cartographic visualization replaces a second role - understanding and explanation - that was satisfied by printed maps. Salvador is one of the most important brazilians metropolis. The project that we discuss have as targets construction of salvador database to permit understanding of urban space through use of thematic cartography. Several steps of project include data acquisition, database formation using data conversion and results visualization through interactive, hypermedia and thematic cartography.

title	A proposed system for integrating design and production in the precast building industry
source	The Int. Journal of Construction IT 7(1), pp. 72-83
summary	The UK construction industry is going through a major re-appraisal, with the objective of reducing construction costs by at least 30% by the end of the millennium. Precast and off-site construction are set to play a major role in improving construction productivity, reducing costs and improving working conditions. In a survey of current practices in the prefabrication industry, it was concluded that the industry is far behind other manufacturing-based industries in terms of the utilisation of IT in production planning and scheduling and other technical and managerial operations. It is suggested that a systematic, integrated, computer-aided, approach to presenting and processing information is needed. The objective of this paper is to introduce and discuss the specifications of an integrated intelligent computer-based information system for the precast concrete industry. The system should facilitate: the integration of design and manufacturing operations; automatic generation of production schedules directly from design data and factory attributes; and generation of erection schedules from site information, factory attributes and design data. It is hypothesised that the introduction of such a system would reduce the total cost of precasting by 10% and encourage clients to choose precast components more often.
