summary The proposal of a model to present contents, intends to consolidate the cooperation among the fields of knowledge that will contribute to introduce this presentation in virtual environments. This proposal intends to continue the work developed in the ALFA T-GAME Project (Teaching Computer Graphics and Multimedia), financed by the European community. The results of this ALFA Project, mainly for architecture, acquired a special meaning due to the relevant presence of images in different specialized courses, that require a synthesis for its versatility and interaction in digital means. The majority of the materials produced is in the early stages of the development and structure of contents. In this way, the project will seek results that contribute to the new ways of presenting the contents that collaborate with the Architecture teaching/learning, from the interchange of the acquired experience, both in e-learning technology and the disciplinary area of Architecture.

summary One of the most important aspects architects need to consider fairly early on is that of energy saving, cost, thermal comfort and the effect on the environment in terms of CO2 emissions. At present, during the early design stage of a building, different options are assessed using simple tools (tables, graphs and software) that contain a large number of assumptions the very nature of which can bias choice or possibly lead to an inappropriate solution. It can be argued that the only way to provide a rational assessment of options is to use calculation methods that represent in detail the physical processes involved; this usually involves the use of dynamic thermal models. Furthermore if this tool is also used during detailed design it would introduce a consistency that is normally absent from the analytical design process. Many designers are of the opinion that, because not all details are known, then such tools are not suitable for application at early stages in the design. This view can be challenged because, even at the concept stage, a great deal is known about a building. This paper aims to show that a general description of a building can be used to generate sufficient data to drive a valid analysis using a detailed thermal model at the early sketch stage of the design process. The paper describes the philosophy, methodology and the interface developed to achieve this aim. The interface guides the user through the input process using a series of screens giving options for keywords used to describe the building; comprehensive default data built into the software are then attached to these keywords. The resulting data file is a building description that is the best possible interpretation of the design intent. This can then be used to assess options and guide towards a final design.

summary This paper explains how to use animated drawings created with a commercial portable pen to understand and teach design process. By recording and replaying pen strokes, the Logitech Io digital pen allows us to examine the drawing process. We have been using the pen to collect expert drawings, analyse the techniques and then teach drawing strategies. The software’s animation timeline engages viewers by giving narrative sequence to a drawing, revealing sub-steps of the design or drawing process for interactive examination and discussion. The timeline allows viewers to pull apart layers of information, revealing initial strokes of complicated drawings, separating overlaid corrections and facilitating stroke counting for protocol analysis. In the classroom, students can see a variety of expert drawing techniques, use the pen in class and then immediately compare animated versions of their own efforts and expert examples. The ease of collecting new examples makes it possible to widen the range of examples to unconventional techniques.

title Modulation and Mathematics in Generative Building Design
source Architecture in the Network Society [22nd eCAADe Conference Proceedings / ISBN 0-9541183-2-4] Copenhagen (Denmark) 15-18 September 2004, pp. 195-200
summary The rise of design computation as a paradigm in design process has certainly brought increased attention to the mathematical basis of form giving in architectural design. Numerous types of generative systems ranging from shape grammars to parametric design have been developed in the past, where computers are used as a tool to generate building form automatically. This paper focuses on the role of number sequences and mathematical methods of controlling and introducing systematic change (modulation) to generative systems. In a graduate level class, VBA programming through a CAD system was used to develop software that can parametrically generate 2-d and 3-d forms. As a conclusion, the paper argues that forms generated as such are not monotonous, and that being particularly attentive to the mathematical basis of variation and change in parametric generators allows one to explore change in a more systematic fashion.

source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary The didactic activity related to the teaching of Perspective has been revised considering the possibility offered by the computing tools. This review must evaluate the potentialities of concepts and procedures related to the traditional techniques as sources for architectural graphics expression, before suggesting its suppression. It is possible to improve the accuracy and quickness controlling the visualization parameters of three-dimensional models. On the other hand, it is necessary to explore the development of the ability to construct quick hand made perspectives (sketches). This work searches for the development of a structure to the teaching process, which emphasizes the potentiality of both ways, traditional and computerized. It explores the flexibility of teaching, from face to face to distance learning, and introduces an enlarged structure of knowledge able to support the traditional and also a computerized process of representation.

summary Internet has made the use of computer based teaching tools more popular then ever. Little attention has been paid to methods for providing schoolbooks in hypertext environment, though. The objective of this research was to develop propositions of methods and tools specifically for presenting textbook in interactive digital environments, paying attention to the characteristics and demands of contemporary youth and the characteristics and potentialities of hypertext systems, specially its associative quality, similar to those of the human mind. The theory on which this article is based is brought by David Ausubel.s cognitive pedagogy and its similarity to web systems, especially those which are hypertext based.

source SIGraDi 2004 - [Proceedings of the 8th Iberoamerican Congress of Digital Graphics] Porte Alegre - Brasil 10-12 november 2004
summary The supremacy of the digital means of representation and communication and the resulting shift of the manual means in the field of design and architecture, have engendered multiple opinions and literature. They focus and analyze the virtues and risks, the losses and substitutions, and the different expressive, productive and conceptual results of their leading role in the creative process. Furthermore, if we consider both as two extremes, apparently opposed, a broad panorama of combinations and additions are produced by the emerging group of hybrid practices. This motivated the development of a research project in the Universidad Nacional del Litoral de Santa Fe, Argentina, under the Program CAI+D 2000 dealing with Design and the Analog – Digital Means. From this project emerged a collection of conceptual speculations and experimentations in the extended field of representation, extended by the incorporation of new means and hybridations, searching for new parameters and methods for professional training and practice. Key words: analog, digital, graphics, means, representation.

summary The proposal of "Urbamedia" is to undertake the development of 3D virtual and interactive models of historical areas of Latin-American cities. The selected zone is the "Mayo Avenue" including the "Mayo Square", an historical place of the city of Buenos Aires, Argentina; this project is financed by the National Agency of Scientific and Technological Development of Argentina and the University of Buenos Aires.We are presenting the first experimental model of the "Mayo Square" that has been developed at ABACUS, Department of Architecture & Building Aids Computer Unit, University of Strathclyde UK. combined with a system analysis of urban activities using the “Atlas.ti” CAQDAS software.This particular use of the “Atlas.ti” software is under experimental applications to this type of urban analysis procedures; allowed us the possibility to analysed a set of activities by means of graph theory as result of a series of interviews to the people working in the area. We are also looking to include historical areas of three cities: Mar del Plata, Rosario and Santa Fe (Argentina) and eventually other cities from Latin América as Rio de Janeiro and Habana.Due that ABACUS has a strong experience in city modelling plus the powerful software and hardware used there, we must develop a VRML customized menu to be adapted to our low cost PC equipment. The 3D model will be used mainly in urban design simulation procedures and the idea is to extend to other type of simulations of the environmental parameters.

title FABRICATION: EXAMINING THE DIGITAL PRACTICE OF ARCHITECTURE
source Proceedings of the 23rd Annual Conference of the Association for Computer Aided Design in Architecture and the 2004 Conference of the AIA Technology in Architectural Practice Knowledge Community / ISBN 09696665-2-7] Cambridge (Ontario) 8-14 November, 2004.
summary We are presenting design ideas, technical innovation, and fabrication expertise that address crucial issues. Authors investigate how to effectively design and practice architecture with automated prototyping and manufacturing. We want to understand where this might lead, and how it might change the nature of architecture itself. We are just beginning to discover the opportunities to be found in integrating automated fabrication within the practice of architecture. At the same time, the new century has brought very mixed perspectives on confident Modern progress. A cautious scrutiny of 'innovation' is needed. Fabrication is an old word with the straightforward meaning, to make. The roots of the word lead to the origins of architecture. Making has been considered a virtue by ancient writers and modern politicians alike. Fabrication (and homo faber, 'one who makes') have served as fundamental terms that constitutions and contract laws have been built upon. Shaping and working with materials is at the core of Western civilization. However at a point in human history where nature is steadily being replaced by human artifice, the consequences of making are far from simple. Whether for good or ill, our new fabricated environment is transforming the world.

title The DXI Experience. Ten Years of Design Visualization Developments in an Educational Laboratory Context
source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 71-77
summary Design visualisation is an essential aspect of virtually every form of design enquiry. The effects of potential environmental interventions may be simulated in order to gain the types of insights, which cannot be acquired easily from two-dimensional notations. Three-dimensional representations may be generated for very different reasons. The most direct form of design imaging is traditionally for the benefit of the designer him/herself, in order to test whether the working concepts offer fitting solutions to the complex array of design conditions such as context, programme and feasibility. Alternately, images may be generated for the benefit of communication, in order to offer insights into the expected workings of a particular proposal (possibly including alternatives). This may lead to greater understanding and possibly to reaching consensus amongst different ‘actors’ involved in the design and realisation process. In many cases the results of such visualisation studies contribute to ‘bridging the gap’ between the professionals and other parties involved more indirectly in design decision-making or the appraisal of the proposals. Designers can use distinctly different methods when going about such imaging procedures. Their choices for particular techniques may depend on their familiarity or the availability of certain media devices. Being confronted with new modelling and/or visualisation instruments can stimulate the interest in fresh approaches. In this respect, the design education environment can play an important role in not only teaching ‘proven’ applications to future designers, but also in creating a platform for the active development of innovative approaches to the design visualisation practices: education as a ‘laboratory’ for new insights and potentially a ‘breeding ground’ for the extension of the designer’s instrumentation. This contribution documents the experiences gained in some ten years within an educational application, involving active use of design driven media applications. The emphasis lies on the evolvement of techniques for eye-level imaging, whereby use can be made of different types of models: physical scale models as well as digital, virtual models. Changing attitudes towards dynamic and serial vision are considered, whereby storyboard approaches on the level of integral presentation are considered. By analysing a selection of cases and their underlying approaches an indication is given of the changing attitudes and combinations of multimedia techniques, which offer opportunities to design visualisation and communication.

title Towards a Virtual Design Media Museum. Identifying, Structuring and Presenting Design and (Re) Presentation Media Artifacts
source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 122-132
summary Designing is largely a process of (inter)active imaging. The evolvement of a design concept from preliminary design proposal towards spatial and material environment generally follows an uncertain path through uncharted landscape; a journey of exploration which requires both rational and creative consideration, frequently involving the interchange of information within a design team and collaboration with representatives from different contributing disciplines. Designs are conceived, worked out and specified step by step (roughly speaking from ‘rough to fine’) in iterative design ‘loops’. All the time the designer tries to determine which ‘course’ should be taken, by considering reference material, by reflecting on conceptions developed previously and by generating specific options aimed at furthering the ‘concretisation’ of the end product. In the course of such a trajectory, visual information is continually being developed, selected, tested, and subsequently either discarded or perfected. From early times architects have been considered not only as knowledgeable ‘experts’ in the field of building as a craft, but also as ‘creative directors’ of such development processes. The architect should be capable of not only conjuring up visions of the future spatial and material form of the building, but also of conveying these to the other ‘actors’ involved in the initiation and building process. Such ‘sharing’ of information is necessary in order to generate sufficient understanding, consensus, enthusiasm, as well as means. To become more than ‘figments of the imagination’, the designer’s ideas need to be ‘pinned down’ (even if they are not yet entirely finished) and communicated by using some form of reliable – and preferably readable – ‘language’ for design development and communication.

title View from the Road: Environmental Simulation for the Fractal City of Rhine Ruhr
source Spatial Simulation and Evaluation - New Tools in Architectural and Urban Design [Proceedings of the 6th European Architectural Endoscopy Association Conference / ISBN 80-227-2088-7], pp. 43-47
summary Highway seems to be more an issue of traffic planning than of urban design. But the highway can be a very important factor for the modern city pattern. Highways shape the spatial form of the fractal city. The modern highway can define new cores outside and “interior edges” within the city. Seen as a planning tool, highways are the great neglected opportunity in city and regional design. The 1st Architecture Biennial, 1ab, taking place from May 2003 to July 2003 in Rotterdam, explores the creative potentials of modern highways worldwide. An international research team discovered the spatial functions of highways in modern agglomerations. This lecture will give an overview of the results of the worldwide analyses and the design projects that had been undertaken. Both authors are members of the German research team. The German team examined the A 42 running through the Ruhrgebiet, a former coal and steal area in western Germany. The Ruhr Area is converting from an industrially orientated region to an agglomeration of high technology and science. But the regional image remains the same due to the fact that the changes cannot be seen, neither physically, nor from the road. Here, the highway could be used as a catalyst supporting and structuring the spatial changes to make them more legible for the people of Rhine-Ruhr. The nature becomes the most important tool of highway design. Landscape forms a linkage between the different cities of the region. Together with the A 40 and other local highways the region becomes the most important (and largest) public space of the new Rhine-Ruhr. The highway seen as a work of urban art can be designed only from the perspective of the driving car.

summary This paper presents the preliminary results of an architectural design studio research developed with undergraduate students of UNISINOS architecture course. The aim was to search for a tool that potentially would allow them to use artificial lighting as element of architectural composition and characterization of the project. The architectural design could be defined as a virtual anticipation of the real architectural object. Being previous to the construction of the architectural object, it is an exploration of a possibility of existence of that same object that is figured in the shown form. As result, the issue of representation takes the status of logical proposition, from which is possible to verify if the tentative solution proposed by the designers could actually have an existence in the world and, if it.s true, fully evaluate its potential. This way it would be possible for the designers to also critically reflect about their own design practice.

summary BIM is an IT-enabled approach that supports enhanced design integrity, efficiency and quality through the distributed access, exchange and maintenance of building data (Haymaker and Suter, 2007; Fischer and Kunz, 2004). More recently, many universities have responded to the adoption of BIM in the profession, by gradually introducing the practice into the curricula (i.e. Cory and Schmelter-Morret, 2012; Ibrahim, 2007; Plume and Mitchell, 2007). Focusing on collaboration – one of the most important aspects of BIM, this paper presents two approaches to implementing BIM in architectural curricula with a focus on collaboration but from two different collaboration scales. Through observation and refl ection of these two approaches to teaching BIM, the paper concludes by discussing BIM curriculum design.

summary This paper presents results from our basic computer education at the School of Architecture in Copenhagen, a snap shot of where we are now. Two years ago it was made obligatory for the students to attend a two week computer course in both their first, and second year. The aim of these courses is to teach the students to experiment with form, and to use the computer for presenting their ideas and projects. Light is central in both courses, and in our development of the courses. The last years we have been studying light trying to develop methods, that makes it possible for the students to create a credible lightning of their 3d models. These studies has raised more questions than answers, but we have succeeded in finding some techniques, that obtained the wanted results.

title CONTEXTUALIZATION AND EMBODIMENT IN CYBERSPACE

summary The introduction of VRML (Virtual Reality Markup Language) in 1994, and other similar web-enabled dynamic modeling software (such as SGI’s Open Inventor and WebSpace), have created a rush to develop on-line 3D virtual environments, with purposes ranging from art, to entertainment, to shopping, to culture and education. Some developers took their cues from the science fiction literature of Gibson (1984), Stephenson (1992), and others. Many were web-extensions to single-player video games. But most were created as a direct extension to our new-found ability to digitally model 3D spaces and to endow them with interactive control and pseudo-inhabitation. Surprisingly, this technologically-driven stampede paid little attention to the core principles of place-making and presence, derived from architecture and cognitive science, respectively: two principles that could and should inform the essence of the virtual place experience and help steer its development. Why are the principles of place-making and presence important for the development of virtual environments? Why not simply be content with our ability to create realistically-looking 3D worlds that we can visit remotely? What could we possibly learn about making these worlds better, had we understood the essence of place and presence? To answer these questions we cannot look at place-making (both physical and virtual) from a 3D space-making point of view alone, because places are not an end unto themselves. Rather, places must be considered a locus of contextualization and embodiment that ground human activities and give them meaning. In doing so, places acquire a meaning of their own, which facilitates, improves, and enriches many aspects of our lives. They provide us with a means to interpret the activities of others and to direct our own actions. Such meaning is comprised of the social and cultural conceptions and behaviors imprinted on the environment by the presence and activities of its inhabitants, who in turn, ‘read’ by them through their own corporeal embodiment of the same environment. This transactional relationship between the physical aspects of an environment, its social/cultural context, and our own embodiment of it, combine to create what is known as a sense of place: the psychological, physical, social, and cultural framework that helps us interpret the world around us, and directs our own behavior in it. In turn, it is our own (as well as others’) presence in that environment that gives it meaning, and shapes its social/cultural character. By understanding the essence of place-ness in general, and in cyberspace in particular, we can create virtual places that can better support Internet-based activities, and make them equal to, in some cases even better than their physical counterparts. One of the activities that stands to benefit most from understanding the concept of cyber-places is learning—an interpersonal activity that requires the co-presence of others (a teacher and/or fellow learners), who can point out the difference between what matters and what does not, and produce an emotional involvement that helps students learn. Thus, while many administrators and educators rush to develop webbased remote learning sites, to leverage the economic advantages of one-tomany learning modalities, these sites deprive learners of the contextualization and embodiment inherent in brick-and-mortar learning institutions, and which are needed to support the activity of learning. Can these qualities be achieved in virtual learning environments? If so, how? These are some of the questions this talk will try to answer by presenting a virtual place-making methodology and its experimental implementation, intended to create a sense of place through contextualization and embodiment in virtual learning environments.

summary This work intends to contribute to the use of techniques to represent free forms in didactic activities. It enlarges a previous study using only one technique to represent parametric curves and surfaces. It includes the NURBS technique, without discharging the BEZIER technique used before. Some exercises were structured using both techniques to model a representative example of Architecture: the Ronchamp Chapel . architect Le Corbusier. The tasks were compared to highlight the knowledge elements existing in both activities and its necessity of enlargement to move from one to another. Its is observed that the use of different techniques, as NURBS and Bezier, emphasize the specific characteristics of the geometric entities, establishing the control of parameters for free forms in the context of architectural graphics.

title Identification and Visualisation of Construction Activities’ Workspace Conflicts Utilising 4D CAD/VR Tools
source eDesign in Architecture: ASCAAD's First International Conference on Computer Aided Architectural Design, 7-9 December 2004, KFUPM, Saudi Arabia
summary This work addresses the problem arising on all construction sites: the occurrence of workspace interference between construction activities. From a site space planning context, this problem can lead to an inevitable roadblock to the progress of the scheduled construction operations. In real situations, when the spatial congestions occur, they could reduce productivity of workers sharing the same workspace and may cause health and safety hazard issues. The aim of this paper is on presenting a computer-based method and developed tool to assist site managers in the assignment and identification of workspace conflicts. The author focuses on the concept of ‘visualising space competition’ between the construction activities. The concept is based on a unique representation of the dynamic behaviour of activity workspace in 3D space and time. An innovative computer-based tool dubbed PECASO (Patterns Execution and Critical Analysis of Site-space Organisation) has been developed. The emerging technique of 4D (3D + time) visualisation has been chosen to yield an interesting 4D space planning and visualisation tool. A multi-criteria function for measuring the severity of the workspace congestions is designed, embedding the spatial and schedule related criteria. The paper evaluates the PECASO approach in order to minimise the workspace congestions, using a real case study. The paper concludes that the PECASO approach reduces the number of competing workspaces and the conflicting volumes between occupied workspace, which in turn produces better assessment to the execution strategy for a given project schedule. The system proves to be a promising tool for 4D space planning; in that it introduces a new way of communicating the programme of work.

summary Visualization has been used for many years as an important way of presenting architectural design and projects. However, beyond design, planning urban areas requires the analysis of different factors. Urban regulations are planning tools used to control and/or stimulate changes in the urban structure and to reproduce a certain level of quality of the urban milieu. Land area, built area, plot rate, average building height, and other important attributes can be easily obtained from the geometric objects in the city model or explicitly associated to them. This paper presents a system, CityZoom, which integrates several performance tools that allow the simulation of different attributes related to a planned or existing city. These attributes are shown in different ways either as tables of attribute values estimated from model evaluation, or 3D scenarios where the user can navigate and observe realistic shadows and daylighting estimation based on the concept of solar envelope.

summary This paper presents an updated evaluation of an experience of applying computer graphics, virtual reality and Internet resources in the teaching of technical graphics at the University of Brasilia, Brazil. It differs from a previous paper (Pratini, 2004) for the addition of an overview of the course, the context and the new teaching methodology. It is an extended, more detailed paper, which includes examples, and closes with some results of surveys on the didactic material and the methodology. Our motivation for this experiment is the fact that most of the students have a lack of previous knowledge on the basis of drawings, resulting difficulties in both understanding and visualizing technical drawings. In this experiment, we introduced VRML 3D modeling in addition to CAD and regular pencil-and-paper drawings study and practice. To support the learning of this broad knowledge not present in the technical graphics bibliography, we first provided a website with animations and virtual reality resources. Since 2003 we are providing a CD-ROM containing all the former website material which is updated each semester. At the present time, the CD-ROM contains almost all the needed didactic material and software for the one semester technical graphics course. This experience was intended to improve and to support learning in a way that motivates the students, young people who are used to play video and computer games. Classes, website and CD-ROM material were conceived to take advantage of computers´ interactivity and animated resources. The use of computers´ technology and new media to support the learning resulted a new methodology and several new unanswered questions.
