title REAL SCALE MODEL VS. COMPUTER GENERATED MODEL
source Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary Advances in electronic design and communication are already reshaping the way architecture is done. The development of more sophisticated and user-friendly Computer Aided Design (CAD) software and of cheaper and more powerful hardware is making computers more and more accessible to architects, planners and designers. These professionals are not only using them as a drafting tool but also as a instrument for visualization. Designers are "building" digital models of their designs and producing photo-like renderings of spaces that do not exist in the dimensional world.

The problem resides in how realistic these Computer Generated Models (CGM) are. Moss & Banks (1958) considered realism “the capacity to reproduce as exactly as possible the object of study without actually using it”. He considers that realism depends on: 1)The number of elements that are reproduced; 2) The quality of those elements; 3) The similarity of replication and 4) Replication of the situation. CGM respond well to these considerations, they can be very realistic. But, are they capable of reproducing the same impressions on people as a real space?

Research has debated about the problems of the mode of representation and its influence on the judgement which is made. Wools (1970), Lau (1970) and Canter, Benyon & West (1973) have demonstrated that the perception of a space is influenced by the mode of presentation. CGM are two-dimensional representations of three-dimensional space. Canter (1973) considers the three-dimensionality of the stimuli as crucial for its perception. So, can a CGM afford as much as a three-dimensional model?

The “Laboratorio de Experimentacion Espacial” (LEE) has been concerned with the problem of reality of the models used by architects. We have studied the degree in which models can be used as reliable and representative of real situations analyzing the Ecological Validity of several of them, specially the Real-Scale Model (Abadi & Cavallin, 1994). This kind of model has been found to be ecologically valid to represent real space. This research has two objectives: 1) to study the Ecological Validity of a Computer Generated Model; and 2) compare it with the Ecological Validity of a Real Scale Model in representing a real space.

title A Computer-based Approach for Teaching Daylighting at the Early Design Stage
source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 181-190

summary This paper has reviewed the literature on the teaching of daylight systems design in architectural education, and found that traditionally such teaching has evolved around the prediction of the Daylight Factor (DF%), i.e. illuminance, via two methods one studio-based and another laboratory based. The former relies on graphical and/or mathematical techniques, e.g. the BRE Protractors, the BRE Tables, Waldram Diagrams, the Pepper-pot diagrams and the BRE formula. The latter tests scale models of buildings under artificial sky conditions (CIE sky). The paper lists the advantages and disadvantages of both methods in terms of compatibility with the design process, time required, accuracy, energy-consumption facts, and visual information.

This paper outlines a proposal for an alternative method for teaching daylight and artificial lighting design for both architectural students and practitioners. It is based on photorealistic images as well as numbers, and employs the Lumen Micro 6.0 programme. This software package is a complete indoor lighting design and analysis programme which generates perspective renderings and animated walk-throughs of the space lighted naturally and artificially.

The paper also presents the findings of an empirical case study to validate Lumen Micro 6.0 by comparing simulated output with field monitoring of horizontal and vertical illuminance and luminance inside the highly acclaimed GSA building in Glasgow. The monitoring station was masterminded by the author and uses the Megatron lighting sensors, Luscar dataloggers and the Easylog analysis software. In addition photographs of a selected design studio inside the GSA building were contrasted with computer generated perspective images of the same space.

title The Use of An Interactive Animation Viewer in Presenting Architectural Design
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary This paper analyzes the use of a 31) hypermedia system in architectural presentation. It first reviews the current process of using computer animation in architectural presentation and identifies problems in the current process. The research assumes that a new approach using the hyper-model environment and animation together would provide a better environment for presenting architectural animation. An interactive animation viewer is designed and developed using the new approach. A sample architectural animation is presented using a tape-recorded animation player, a normal animation player, the interactive animation viewer, and a real-time animation player. The analysis of the result is made by a comparison in terms of image quality, speed, user interactions, object hyperlinkage, scene complexity, and information transmission on using different systems in presenting the same material. A conclusion is drawn to show the advantages of using the new approach. Limitations on using the new approach are identified too.

summary The rapid speed of computer development brings new technologies, and these advances require innovative investigations to apply them optimally in the field of architecture. Burkett (1984) demonstrated that computer graphics can ‘provide an excellent opportunity for exploring solar issues in building redesign’. With one of the latest computer technologies, the "hyper-model” environment, this research investigates how to environment can become an aid in the design and decision support area. The research first reviews the communication between the architect and the client as described by Salisbury (1990). The review indicates that an interactive 3D hypermedia paradigm, with quick response, fast data manipulation and 3D visualization, offers a better communication media between the architect and the client. This research applies the "hyper-model” environment to design and develop a new methodology in collecting, analyzing, and presenting solar data. It also endeavors to show the possibilities of using the environment in design process.

summary By looking at the well-developed discipline of language teaching, we can improve instruction of computer aided design communication. Language teaching not only breaks down a complex field into attainable steps, but also shows how learning strategies and attitudes can enhance mastery. Guiding students in learning approaches will equip them to deal with constantly changing technology. Even at an introductory level, awareness of the learning process can heighten learning. Thus, giving a conceptual framework and enhancing resource-finding, brainstorming and coping abilities will lead to threshold competence. Practicing these strategies on realistic projects hones the ability to connect concepts to actual situations. Both design or research projects exercise resource-usage, task management, crisis management, but specifically, collaboration exercises which engage the students with a real audience can provide strong motivation and link academic study to practical concerns. Ideas about teaching techniques are documented with examples from the University of Hong Kong.

title Modeling and rendering architecture from photographs: a hybrid geometry- and image-based approach
source SIGGRAPH'96, New Orleans, Louisiana
summary We present a new approach for modeling and rendering existing architectural scenes from a sparse set of still photographs. Our modeling approach, which combines both geometry-based and imagebased techniques, has two components. The first component is a photogrammetricmodelingmethodwhich facilitates the recovery of the basic geometry of the photographed scene. Our photogrammetric modeling approach is effective, convenient, and robust because it exploits the constraints that are characteristic of architectural scenes. The second component is a model-based stereo algorithm, which recovers how the real scene deviates from the basic model. By making use of the model, our stereo technique robustly recovers accurate depth from widely-spaced image pairs. Consequently, our approach canmodel large architectural environmentswith far fewer photographs than current image-based modeling approaches. For producing renderings, we present view-dependent texture mapping, a method of compositing multiple views of a scene that better simulates geometric detail on basic models. Our approach can be used to recover models for use in either geometry-based or image-based rendering systems. We present results that demonstrate our approach's ability to create realistic renderings of architectural scenes from viewpoints far from the original photographs.

title Computing Assisted Drafting and Design: new technologies for old problems
source Center for the study of architecture, Bryn Mawr, Pennsylvania
summary In past issues of the Newsletter, George Tressel and I have written about virtual reality and renderings. We have each discussed particular problems with the technology, and both of us mentioned how compelling computer visualizations can be. In my article ("Virtual Reality and Rendering," February, 1995, Vol. 7, no. 4), I indicated my concerns about the quality of the scholarship and the level of detail used in making renderings or virtual worlds. Mr. Tressel (in "Visualizing the Ancient World," November, 1996, Vol. IX, no. 3) wrote about the need to distinguish between real and hypothetical parts of a visualization, the need to differentiate materials, and the difficulties involved in creating the visualizations (some of which were included in the Newsletter in black-and-white and on the Web in color). I am returning to this topic now, in part because the quality of the images available to us is improving so fast and in part because it seems now that neither Mr. Tressel nor I treated all the issues raised by the use of high-quality visualizations. The quality may be illustrated by new images of the older propylon that were created by Mr. Tressel (Figs. 1 - 3); these images are significantly more realistic than the earlier ones, but they do not represent the ultimate in quality, since they were created on a personal computer.

title SIMULATION FOR ANALYSIS: REQUIREMENTS FROM ARCHITECTURAL DESIGN
source Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary Computerization has been a positive factor in the evolution of both kinds of analysis with respect to cost, availability and efficiency. Knowledge-based systems offer an appropriate implementation environment for normative analysis which can be more reliable and economical than evaluation by human experts. Perhaps more significant is the potential of interactive computer simulation where designs can be examined intuitively in full detail and at the same time by quantitative models. The advantages of this coupling are evident in the achievements of scientific visualization. Another advantage of computational systems is that the analysis can be linked to the design representation, thereby adding feedback to the conventional visualization of designs in drawing and modeling systems. Such connections are essential for the development of design guidance systems capable of reflecting consequences of partial inadequacies or changes to other aspects in a transparent and meaningful network of design constraints.

The possibilities of computer simulation also extend to issues inadequately covered by normative analysis and in particular to dynamic aspects of design such as human movement and circulation. The paper reports on a framework for addressing two related problems, (a) the simulation of fire escape from buildings and (b) the simulation of human movement on stairs. In both cases we propose that current evaluation techniques and the underlying design norms are too abstract to offer a measure of design success, as testified by the number of fatal accidents in fires and on stairs. In addition, fire escape and stair climbing are characterized by great variability with respect to both the form of the possible designs and the profiles of potential users. This suggests that testing prototypical forms by typical users and publishing the results as new, improved norms is not a realistic proposition for ensuring a global solution. Instead, we should test every design individually, within its own context. The development of an affordable, readily available system for the analysis and evaluation of aspects such as fire escape and stair safety can be based on the combination of the technologies of virtual reality and motion capture. Testing of a design by a number of test people in an immersion space provides not only intuitive evaluations by actual users but also quantitative data on the cognitive and proprioceptive behaviour of the test people. These data can be compiled into profiles of virtual humans for further testing of the same or related designs.

title DEFLECT: A Computer Aided Learning Package For Teaching Structural Design
source Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 253-262
doi https://doi.org/10.52842/conf.ecaade.1996.253
summary The teaching of structures and its integration with design teaching has been seen as one of the major problems in design education in schools of architecture world-wide. A number of suggestions have been put forward to improve the quality of teaching in structures in architecture. These include the production of computer based learning materials, and the use of the computer as a ‘substitute’ tutor.

This paper reports on a SHEFC funded project jointly carried out by the Department of Civil Engineering, University of Paisley, the Mackintosh School of Architecture, and Lamp Software. The project aims to build a computer-assisted learning package on the response of structures to load. The software will be used as an interactive teaching tool for both architectural and engineering students.

The package has three levels: Beginners (Level 1), Intermediate (Level 2) and Advanced (Level 3). The first two levels have been completed after continuous feedback from both institutions. Level 1 is geared towards architectural and engineering students to help them understand structural behaviour of building components, such as deflection. Level 2 is a graphical editor that enables students to draw precisely the structure of their designs, investigate the deflection of structural members and identify areas of tension and compression. Level 3 is a design tool aimed at architectural and civil engineering students where they can design and analyse realistic structures by choosing structural members from a library, and specify materials and multiple loads.

Prior to its final release, the software package was appraised by students from both institutions. Analysis of results from questionnaires revealed that students expressed a great deal of 'satisfaction' with many of its teaching and learning attributes. The outcome of this project will promote and enhance students’ understanding of the response of structures to load; it will also help students grasp the impact of varying building materials and cross sectional properties on the structural form.

title Possible Futures in Computer Art Generation
source International Conference on Generative Art
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 EFFECTIVENESS OF MODELS
source Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary Architects use many types of models to simulate space either in their design process or as final specifications for building them. These models have been proved useful or effective for specific purposes. This paper evaluates architectural models in terms of five effectiveness components: time of development, cost, complexity, variables simulated and ecological validity. This series of models, used regularly in architecture, are analysed to finally produce a matrix that shows the effectiveness of the different models for specific purposes in architectural design, research and education. Special emphasis is given to three specific models: 1/10 scale, full-scale and computer generated.

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.

summary The production of near-photorealistic images of buildings is becoming increasingly common. The software to produce reasonably sophisticated images being available at affordable prices and the increasing power of generally affordable computers have contributed to this trend. It is also probably the case that the run-of-the-mill architectural practice sees the competition producing this kind of image with a superficially beguiling quality and follow suit. What we ask in this paper is whether we should be more thoughtful about the kind of image used? Should the kind of image chosen to suit the stage of the design that it applies to and the nature of the human agents viewing the image? Of course, in posing the question we imply our answer, that it should. What we do in this paper is to illustrate why we feel it should and what the consequences are for the education of architects who are about to join the world of practice.

title Human Interpretation of Computer Generated Architectural Images
source Approaches to Computer Aided Architectural Composition [ISBN 83-905377-1-0] 1996, pp. 61-70
summary The hardware and software used by architects to produce drawings and rendered images (static and dynamic) has advanced over the past decade to the point where it is now routine for architects to add rendered (and otherwise manipulated) images to the more routine 2D drawing as a product to convey the building to others. Although the 2D drawing (as plan section, elevation or detail) remains the fundamental and most prevalent kind of image being produced by architects, we regard it as timely to take stock of the effect of how we interpret the computer generated images that are being produced. We want to address the question of how humans, with a wide range of backgrounds and predispositions interpret such images. This paper takes previous studies which consider image interpretation and image generation by computer and begins to apply the techniques and jcndings to contemporary CAD image making.

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 Awareness Space in Distributed Social Networks
source Proceedings of the Ninth International Conference on Computer Aided Architectural Design Futures [ISBN 0-7923-7023-6] Eindhoven, 8-11 July 2001, pp. 615-628
summary In the real work environment we are constantly aware of the presence and activity of others. We know when people are away from their desks, whether they are doing concentrated work, or whether they are available for interaction. We use this peripheral awareness of others to guide our interactions and social behaviour. However, when teams of workers are spatially separated we lose 'awareness' information and this severely inhibits interaction and information flow. The Theatre of Work (TOWER) aims to develop a virtual space to help create a sense of social awareness and presence to support distributed working. Presence, status and activity of other people are made visible in the theatre of work and allow one to build peripheral awareness of the current activity patterns of those who we do not share space with in reality. TOWER is developing a construction set to augment the workplace with synchronous as well as asynchronous awareness. Current, synchronous activity patterns and statuses are played out in a 3D virtual space through the use of symbolic acting. The environment itself however is automatically constructed on the basis of the organisation's information resources and is in effect an information space. Location of the symbolic actor in the environment can therefore represent the focus of that person's current activity. The environment itself evolves to reflect historic patterns of information use and exchange, and becomes an asynchronous representation of the past history of the organisation. A module that records specific episodes from the synchronous event cycle as a Docudrama forms an asynchronous information resource to give a history of team work and decision taking. The TOWER environment is displayed using a number of screen based and ambient display devices. Current status and activity events are supplied to the system using a range of sensors both in the real environment and in the information systems. The methodology has been established as a two-stage process. The 3D spatial environment will be automatically constructed or generated from some aspect of the pre-existing organisational structure or its information resources or usage patterns. The methodology must be extended to provide means for that structure to grow and evolve in the light of patterns of actual user behaviour in the TOWER space. We have developed a generative algorithm that uses a cell aggregation process to transcribe the information space into a 3d space. In stage 2 that space was analysed using space syntax methods (Hillier & Hanson, 1984; Hillier 1996) to allow the properties of permeability and intelligibility to be measured, and then these fed back into the generative algorithm. Finally, these same measures have been used to evaluate the spatialised behaviour that users of the TOWER space show, and will used to feed this back into the evolution of the space. The stage of transcription from information structure to 3d space through a generative algorithm is critical since it is this stage that allows neighbourhood relations to be created that are not present in the original information structure. It is these relations that could be expected to help increase social density.

summary According to three experimental virtual spaces above, the key factor for experience montage is identified—3D collage. General speaking, the theory of montage describes the connection of space and time. Time is a phenomenon of connection of points. Within 3D virtual space, the influence of Experience Montage generated in the experiments above is examined through the Exploration model (representation + rules + memory + policy = search exploration) proposed by Woodbury in 1996. Through browsing and reading, the originally intact virtual space is dissected into pieces and corners. By duplicated, dismantled and reorganized over this dissected space, a new personalized virtual space is then modeled. As a continuation of previous analysis, latter stages of the study use the Exploration model to explain anew the connection among the representation, rules, memory, and policy of Experience Montage.

title EVALUATION OF THE OSLD HOUSING SYSTEM
source Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary In the production of low-income housing, one of the factors that most affects the low cost of each unit is its mass production. When it comes to building a proposed design it must have been sufficiently studied and evaluated. When designing low-income housing it is convenient to exhaust all the possibilities of simulation in order to produce a prototype that, once built, has reduced the risk of errors. Simulations allow to improve the prototype before proceeding to build it. The Real Scale Model (RSM) has proved to be a better simulation tool than computer generated models or 1:10 scale models. It allows to reproduce and evaluate perceptual experiences as well as being user friendly because most of the spatial variables can be represented. This research is another example of the use and effectiveness of the RSM in the field of design and architectural research.

A Real Scale Model of the basic unit was built by the students of the course Spatial Design Ability dictated by the LEE. The model was first evaluated empty and then a furnishing solution was proposed, built and evaluated. These evaluations were done by another group of students of the Faculty of Architecture and Planning using the Psychological Impressions Measuring Test (IMIP) developed by Luis La Scalea (1991). This test was designed to measure people’s psychological impressions produced by a space, and consists of a semantic differential structured by eleven pairs of opposing adjectives set on a scale of seven levels. The results of this first evaluation were analysed used to modify the prototype which was evaluated again in order to produce a final layout.

title Transformable, Folding Space
source Design Computation: Collaboration, Reasoning, Pedagogy [ACADIA Conference Proceedings / ISBN 1-880250-05-5] Tucson (Arizona / USA) October 31 - November 2, 1996, pp. 45-54
doi https://doi.org/10.52842/conf.acadia.1996.045
summary A group of architectural students in an advanced computer applications course were asked to design a folding or transformable personal space. They were to approach the design using two metaphors - Origami (or papiroflexia ) and Transformer robot toys - in a digital environment. These are familiar ideas evident in toys and furniture. Students found this way of thinking about architectural design foreign and unusual. The results were tentative, but insightful. New architectural forms emerged out of the plasticity, temporality, and speed of the digital medium. Origami and Transformer robots are more than toys. Through them, the Bauhaus notion of point transforms into line, line into plane, plane into solid can now be stretched to include space generated from motion.

The argument for conceptualizing and developing the design within a digital environment was that the operations implied by Origami and Transformers, can be carefully studied in this context. Both processes, or types of objects, are best understood in teens of change in time and space. Digital media offers the dynamic capabilities needed to study distortions, step transformations & movement.
