title	Evaluation of Spatial Perception in Virtual Environments
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 145-148
summary	The 3D environments created by computers can be used as a powerful simulation tool for architecture, especially with inmersive devices, but it is necessary to know properly their spatial characteristics to use it effectively. It is also important to consider their possibilities in communication networks and their implications in contemporary architecture. For this reason, the goal of this research is to evaluate the perception of virtual architectonic spaces in relation to the perception of real architectonic spaces. This research is based on the comparison of experiences of university students in a real space (Entrance Hall of Faculty of Economy) and in the same space modeled by a computer. The evaluation considers tests with stereoscopic helmets and interactive navigation, making questionnaires to characterize the sensation of dimensions, relationships and time for an specific activity. The measuring of real and virtual spaces are made through references (furniture, textures, etc.) or by proportional relations between height, width and depth, in different patterns. The experience also reveals mental schemes to perceive the dimension of architectonic space and the orientation in a real and virtual environment. Besides, the research allows to relate the different levels of complexity and information with the understanding of real architectonic space and modeled space.

title	Architecture and Hyperdocument: Data Shaping Space
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 462-465
summary	The computer interface can't convey the hole experience of walking through a city or a building. Nevertheless, the complexity of all the aspects involved in those threedimensional spaces can be better understood through the non-linearity of the hyperdocument. Each dweller of a city and a building has many layers of relationship with both. The sequence and the extent each observer explores the space is unique. It’s not totally apprehended in a first visit. As the observer knows better that space, his experience changes. A similar situation takes place in a multimedia application. Hence, it's possible to build an analogy between the architectonic or urban structure and a hyperdocument navigation structure. We can also state that the computer is critical to create paths of architectural information through space and time. The 3D model of a city is a powerful basis to structure the hyperdocument navigation. The city can be viewed in separate parts or layers of information. One investigates the city through different aspects of its configuration and explores it in different scales and levels of detail. The images generated from this 3D model can be combined with video, photo, sound and text, organizing the information which gives form to the city. The navigation through this information, addresses the citty by its economy, housing, religion, politics, leisure, projects, symbolic buildings, and other aspects. This paper will discuss these issues through the experiments of the research done at the School of Architecture and Urbanism of the Universidade Federal do Rio de Janeiro. The research group at the "Laboratory of Urban Analysis and Digital Representation" in PROURB (Graduate Program of Urbanism) analyses the city and its buildings using CD-ROMs and websites.

title	Virtual Reality in Architectural Education: Defining Possibilities
doi	https://doi.org/10.52842/conf.acadia.1999.007
source	ACADIA Quarterly, vol. 18, no. 4, pp. 7-9
summary	Introduction: virtual reality in architecture Virtual Reality (VR) is an emergent computer technology for full 3D-simulations, which has a natural application in the architectural work, due that activity involves the complete definition of buildings prior to its construction. Although the profession has a long tradition and expertise in the use of 2D-plans for the design of buildings, the increasing complexity of projects and social participation requires better media of representation. However, the technological promise of Virtual Reality involves many sophisticated software and hardware developments. It is based on techniques of 3D-modelling currently incorporated in the majority of drawing software used in architecture, and also there are several tools for rendering, animation and panoramic views, which provide visual realism. But other capabilities like interactivity and sense of immersion are still complex, expensive and under research. These require stereoscopic helmets, 3D pointers and trackers with complicated configurations and uncomfortable use. Most advanced installations of Virtual-Reality like CAVEs involve much hardware, building space and restrictions for users. Nevertheless, diverse developers are working in Virtual-Reality user-friendly techniques and there are many initial experiences of architectural walk-throughs showing advantages in the communication and development of designs. Then we may expect an increasing use of Virtual Reality in architecture.

title	Time sections, abstract machines
source	International Conference on Generative Art
summary	conditions a time-spatial discontinuity in the urban grid, ancient walls casually discovered in a substrate of the contemporary town needs a surplus of information to be understood and interfaced with their current condition. diagrams diverse chronological stages of the urban evolution are mapped on the area, in order to read the historical stratifications as a multiplicity of signs; this abstract approach leads to consider the roman space as guided by metrics, a system of measure superimposed on the landscape, vs. medioeval spatial continuity, where more fluid relations between the same urban elements create a completely different pattern.assemblage (time sections) a surface, automatically displaced from the medioeval diagram, moves along the z axis, the historical stratification direction, intersecting in various, unpredictable, manners a series of paths; these paths start as parallels, allowing an undifferentiated access to the area, and mutate along their developing direction, intertweening and blending each other; linear openings are cut on the surface, virtually connecting the two levels by light, following the roman grid in rhythm and measure. Projected on the lateral wall, the cadence of the vertical and horizontal elements becomes a temporal diagram of the design process.movement time takes part into the process through two kinds of movement: the first one, freezed when reaches the best results, in terms of complexity, is given by the surface intersecting the tubular paths; the second one is represented by multiple routes walking on which the project can be experienced (in absence of any objective, fixed, point of view, movement becomes the only way to understand relations). Thresholds between typical architectural categories (such as inside-outside, object-landscape etc.) are blurred in favour of a more supple condition, another kind of continuity (re)appears, as a new media, between the different historical layers of the city.

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

title	Posicionamiento de Volúmenes Arquitectónicos Mediante Algoritmos Evolucionistas (Positioning of Architectural Volumes by Means of Evolutionist Algorithms)
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 176-181
summary	Configurational studies involve the groups of elements fulfilling restrictions defined by the designer in Architectural design. According to its necessities and intentions, the planner distributes the components of the group in a certain tridimensional way, establishing a composition. This operative procedure implies a classification system according to typologies that respond to a bigger system, and this in turn to another, until the whole is obtained. From the beginning the pattern should satisfy form restrictions, as well as dimensional and positional restrictions for each part that conforms the whole. Functional requirements are attended for each object satisfying relationships of connectivity and adjacency among them. In this work the parts are restricted by their relative position to a central element. Evolutionary Algorithms (EA) are used to solve this type of problem. Using evolutionary metaphors they originate concepts such as "genes", "chromosomes", "mutation", "crosses” and " population " (among other), which come closer to one of the solutions looked for by the designer, under combinatory stochastic methods. The most appropriate use of EA corresponds to problems of complexity NP-completeness (for example, problems of generation of cases of composition), allowing an efficient although not exhaustive analysis. Applying this technique to the generation of architectural volumes, some obtained results are exemplified.

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 289-294
summary	This paper presents the searching of new building modes for the knowledge of design in curriculum workshops at Facultad de Arquitectura, Diseno y Urbanismo of the Universidad Nacional del Litoral the proposed “research action” program articulates longitudinally in the three cycles of the career, understanding architecture as metaknowledge within a new paradigm of subjectivity, complexity and multidimensionality. In other words, it is recognized a new scenery tending to modify didactic relations. This experimental field looks for conscientious equilibrium between “written culture/audiovisual culture”, and “analog instruments/digital media”. We focus our interest on the “machine interacting with and for men”, looking for harmonious synthesis through a new way of thinking, to allow “real progress”. For turning this idea into action, we organized an alternative and plural team-work in architecture. We called it “experimental workshop”. In this first level the students worked. On a preliminary plan of a “kindergarden”. They developed a divergent process through the 3D simulations (using the software 3DS MAX v2), scale models and sensible sketches. For conclusions, the paper addresses the characteristics of the pedagogic model used and the results achieved.

summary	The insert of the digital technologies in the atmosphere Áulico has left generalizing in a significant way. An example constitutes it the high percentage of students that they manifested general knowledge in the software handling in the introductory course of visual communication, as well as the voluntary presentation of practical works developed with digital means. The necessity of an answer to the requirements that arise of the students sinks to the certainty of a pedagogic compatibility among the matter to try and the teaching attended by the personal computer that would increase the Iconidad and the understanding of a topic of certain complexity like it is the geometry of the space. An educational program designed for the teaching of the Sistema Monge whose general characteristics were presented in the II Ibero-American Seminar of Digital Graph and that it will be applied as experience pilot in the course 2000, it will allow us to respond to the following queries: what place it will be given to the educational program in the formation process in connection with the other pedagogic means.

source	International Conference on Generative Art
summary	This paper is a summary of my last degree in architecture (discussed in December 1999) with Prof. Celestino Soddu and Prof. Enrica Colabella. In this work I had the possibility to reach complexity by a generative approach with the construction of a paradigm that organizes the different codes of project identity. My general objective was to design shape complexity in variable categories : 3d space surfaces, 2d drawings and 2d textures. I was to discover the identity of one of my favourite architects of the 20th century : Antoni Gaudì, by constructing codes relative to shape complexity. I defined my particular objective in the possibility to abduct from Gaudì's imaginary reference the generatives codes that operate in the logical processing I use to create a possible species project. The next step was to verify the exact working of the new generative codes by means of 3d scenaries, that are recognizable as "Antoni Gaudì specie's architecture". Whit project processing on the generative codes and not on a possible resulting shape design, I was able to organize by my general paradigm the attributes of the project's species : different shapes, different attributes (color, scale, proportion), to get to possible and different scenarys, all recognizable by the relative class codes. I chose three examples in Barcellona built during the period 1902 to 1914 : The Parco Guell, Casa Batllò and Casa Milà are the three reference sceneryes that I used to create the generative codes. In the second step I defined different codes that operate in sequence (it is defined in the paradigm) : The generatives codes are only subjective; they are one possible solution of my interpretation of Antoni Gaudì's identity. This codes operate in four differents ways : Geometrical codes for 2d shapes Geometrical codes for interface relations Spatial codes for 3d extrusion of 2d shapes Geometrical codes for 2d and 3d texturing of generated surfaces. By a stratified application of this codes I arrived at one idea for all the generative processes but many different, possible scenaryes, all recognizable in Gaudì's species. So, my final result has made possible sceneryes belonging to related species defined previously. At the end of my research I designed a project by combination : using Antoni Gaudì's generative codes on a new 3d scenary with a shape catalyst : the Frank Lloyd Wright Guggenheim Museum of New York. In this process I created a "hybrid scenary" : a new species of architectural look; a Guggenheim museum planned by Wright with a god pinch of Gaudì.

summary	RioDigital is a text situated on new forms of expression of knowledge over the city. It is a written multimedia whose objective is to place in disposability for the society the complexity of urban space on its multiple historical determinations, of its space, social and cultural forms. It is a research over the potentials of digital art to express the processes of constitution of social forms and constructions of urban space. The motion of works was in the sense of using this language to reconstitute and vivify the history of Rio de Janeiro city in the XX century. The city is an ensemble of symbols that encounters the language in its best form of presentation. The research identified visual documents as films, photos and maps that made possible to reconstruct processes of transformation, worked through the use of digital images technology that allows expression and turns move perceptible the transmission of this history. The digital image is certainly a possibility to represent urban reality. Through movement, illumination of image and of writing it was possible to express to process of construction and reconstruction of space building and social changes. We understand that the condition of citizen is associated with the feeling of belonging, which urban process every time move complex and difficult to understand, that new technologies can through synthesis, connectivity and interactivity expand the capacity of indivils to know the city and act positively with it. It is an intention to amplify the sense of belonging and encourage the action of transform.

title	The Importance of Being Abstract: An Indian Approach to Models
doi	https://doi.org/10.52842/conf.ecaade.1999.101
source	Architectural Computing from Turing to 2000 [eCAADe Conference Proceedings / ISBN 0-9523687-5-7] Liverpool (UK) 15-17 September 1999, pp. 101-109
summary	Traditional Indian way of life is surrounded by ambiguity. This is in direct contrast to an Aristotelian approach, where polarised stands are always taken. A black and white approach tends to yield results speedily, but exhaustive solutions which can explain complexity are usually brute force procedures. Even so, their conclusions in the end are still suspect. The author believes that rich solutions may exist when we use an 'alternate' or abstract synthesized reality to do our modelling instead of relying on analogies and other direct links to the real world. Models that allow synthesis tend to accept ambiguity. The author presents in this paper an 'unconventional' system to represent architecture which has had some amount of success probably because it started of, on pure abstract grounds that allowed ambiguity instead of basing it on an Aristotelian, analytical model.

summary	In this paper an online editing system for eCAADe papers is presented, which is also the technology behind this proceedings volume. On the occasion of the eCAADe 1999 conference in Liverpool, a novel layout for the proceedings was developed. In the course of forthcoming annual conferences, this became the distinctive “look and feel” of the eCAADe proceedings. Due to the complexity, professional typesetting was required for and the authors were disconnected from the publication and layout stage. This paper elaborates on the development and implementation of a web-based tool, which takes care of the typesetting and delegates this activity again to the authors. Neither software installation is required, nor specific training must be completed in advance. On top of this the degree of homogeneity can be raised significantly, thus supporting the editors in charge to concentrate on the task of harmonising the resulting publication output.

summary	The major timber structures have great efficiency and beauty, but not many use in buildings due difficulties to represent and resolve theirs geometrical complexity, regulated by several constructive rules. The spatial richness and attractive of these structures can be a contribution in architecture, and encourage the use of wood. For aid the design and impels innovative solutions we are developing a computer system to program the geometrical regulations and allow a tridimensional visualization of different models with virtual-reality devices. First we are studing the architectural morphology and design process of structures more typically used; beams, trusses, frames and arcs. Establishing theirs proportions, distribution, shapes alternatives and the computational algorithm. In other hand we are evaluating the 3D-visualization in the innovation of designs. Some students of architecture developed in a virtual- system small projects based on other projects designed with traditional media. The models were compare by a panel of professors, considering overall quality and creativity. The results of that experience shows advantages in geometrical innovation, specially in organic shapes user-centered instead of orthogonal compositions. But also some constructive fails, which is necessary to support with related procedures.

title	Performance criteria used in fire safety design
source	Automation in Construction 8 (4) (1999) pp. 489-501
summary	In many countries around the world, building codes are shifting from prescriptive- to performance-based for technical, economic, and social reasons. This move is made possible by progress in fire safety technologies, including the development of engineering tools that are required to implement performance codes. The development of performance-based codes follows a transparent, hierarchical structure in which there are usually three levels of objectives. The top level objectives usually state the functional requirements and the lowest level the performance criteria. Usually, one middle level exists, however, more levels can be used in this hierarchical structure depending on the complexity of the requirements. The success of performance-based codes depends on the ability to establish performance criteria that will be verifiable and enforceable. The performance criteria should be such that designers can easily demonstrate, using engineering tools, that their designs meet them and that the code authority can enforce them. This paper presents the performance criteria that are currently used by fire protection engineers in designing fire safety systems in buildings. These include deterministic and probabilistic design criteria as well as safety factors. The deterministic criteria relate mainly to life safety levels, fire growth and spread levels, fire exposure and structural performance. The probabilistic criteria focus on the incident severity and incident likelihood. Finally, the inclusion of safety factors permits a conservative design and allows for a smaller margin of error due to uncertainty in the models and the input data.

title	Constraints in object-oriented graphics
source	Eindhoven University of Technology
summary	In the area of interactive computer graphics, two important approaches to deal with the complexity of designing and implementing graphics systems are object-oriented programming and constraint-based programming. From literature, it appears that combination of these two has clear advantages but has also proven to be difficult. One of the main problems is that constraint programming infringes the information hiding principle of object-oriented programming. The goal of the research project is to combine these two approaches to benefit from the strengths of both. Two research groups at the Eindhoven University of Technology investigate the use of constraints on graphics objects. At the Architecture department, constraints are applied in a virtual reality design environment. At the Computer Science department, constraints aid in modeling 3D animations. For these two groups, a constraint system for 3D graphical objects was developed. A conceptual model, called CODE (Constraints on Objects via Data flows and Events), is presented that enables integration of constraints and objects by separating the object world from the constraint world. In the design of this model, the main aspect being considered is that the information hiding principle among objects may not be violated. Constraint solvers, however, should have direct access to an object’s internal data structure. Communication between the two worlds is done via a protocol orthogonal to the message passing mechanism of objects, namely, via events and data flows. This protocol ensures that the information hiding principle at the object-oriented programming level is not violated while constraints can directly access “hidden” data. Furthermore, CODE is built up of distinct elements, or entity types, like constraint, solver, event, data flow. This structure enables that several special purpose constraint solvers can be defined and made to cooperate to solve complex constraint problems. A prototype implementation was built to study the feasibility of CODE. Therefore, the implementation should correspond directly to the conceptual model. To this end, every entity (object, constraint, solver) of the conceptual model is represented by a separate process in the language MANIFOLD. The (concurrent) processes communicate by events and data flows. The implementation serves to validate the conceptual model and to demonstrate that it is a viable way of combining constraints and objects. After the feasibility study, the prototype was discarded. The gained experience was used to build an implementation of the conceptual model for the two research groups. This implementation encompassed a constraint system with multiple solvers and constraint types. The constraint system was built as an object-oriented library that can be linked to the applications in the respective research groups. Special constructs were designed to ensure information hiding among application objects while constraints and solvers have direct access to the object data. CODE manages the complexity of object-oriented constraint solving by defining a communication protocol to allow the two paradigms to cooperate. The prototype implementation demonstrates that CODE can be implemented into a working system. Finally, the implementation of an actual application shows that the model is suitable for the development of object-oriented software.

summary	In the early 1990s, the introduction of an extensive CAAD component in the compulsory curriculum of the Faculty of Architecture, Delft University of Technology, stimulated experimentation with computer-based instruction systems. The emergence of the World Wide Web presented new possibilities. Nevertheless, the reasons for investing in Web-based CAAD instruction were mostly pragmatic, i.e. a reaction to necessity, rather than an intention to explore, experiment and revolutionize. One of the problems addressed in our Web-based CAAD instruction is CAAD literacy. Help files and manuals that accompany software have proven to be unsuitable for introductory courses in design computing. This led to the development of a series of dynamic Web-based tutorials, in the form of interactive slide shows. The implementation of the tutorials is based on a cooperative framework that allows teachers and students to contribute at different levels of technical and methodical complexity. The use of the Web in CAAD education also stimulated a more active attitude among students. Despite the limited support and incentives offered by the Faculty, the Web-based CAAD courses became an invitation to intelligent and meaningful use of Web technologies by students for design presentation and communication. This is not only a useful addition to the opportunities offered by CAAD systems but also a prerequisite to new design communities.

title	Unsupervised Dynamic Concurrent Computer-Aided Design Assistant
source	Los Angeles: UCLA
summary	The increasing capability of computer-aided architectural design systems has strengthened the role that the computer plays in the workplace. Due to the complexity of developing new techniques and research, these systems are undertaken mostly by scientists and engineers without significant architectural input (Willey, 1991). The design concept of these systems may be based on a well-defined and well-understood process, which is not yet realized in architectural design (Galle, 1994). The output of such research may not be easily adapted into the design process. Most of the techniques assume a complete understanding of the design space (Gero and Maher, 1987) (Willey, 1991). The description or construction of the design space is always time and space consuming, and the result can never be complete due to the ever-changing nature of architectural design. This research intends to initiate a solution for the above problems. The proposed system is an unsupervised-dynamic-concurrent-computer-aided-design assistant. The “unsupervised” means the learning process is not supervised by the user because it is against the designer's nature to “think-aloud” in the design studio and it also increases the work load. It is dynamic because the size of the knowledge base is constantly changing. Concurrent means that there are multiple procedures active simultaneously. This research focuses on learning the operational knowledge from an individual designer and reapplying it in future designs. A computer system for this experiment is constructed. It is capable of The preliminary result shows a positive feedback from test subjects. The purpose of this research is to suggest a potent computational frame within which future developments may flourish.

summary	Although computer and video games have existed for fewer than 40 years, they are already serious business. Entertainment software, the entertainment industry's fastest growing segment, currently generates sales surpassing the film industry's gross revenues. Computer games have significantly affected personal computer sales, providing the initial application for CD-ROMs, driving advancements in graphics technology, and motivating the purchase of ever faster machines. Next-generation computer game consoles are extending this trend, with Sony and Toshiba spending $2 billion to develop the Playstation 2 and Microsoft planning to spend more than $500 million just to market its Xbox console [1]. These investments have paid off. In the past five years, the quality and complexity of computer games have advanced significantly. Computer graphics have shown the most noticeable improvement, with the number of polygons rendered in a scene increasing almost exponentially each year, significantly enhancing the games' realism. For example, the original Playstation, released in 1995, renders 300,000 polygons per second, while Sega's Dreamcast, released in 1999, renders 3 million polygons per second. The Playstation 2 sets the current standard, rendering 66 million polygons per second, while projections indicate the Xbox will render more than lOO million polygons per second. Thus, the images on today's $300 game consoles rival or surpass those available on the previous decade's $50,000 computers. The impact of these improvements is evident in the complexity and realism of the environments underlying today's games, from detailed indoor rooms and corridors to vast outdoor landscapes. These games populate the environments with both human and computer controlled characters, making them a rich laboratory for artificial intelligence research into developing intelligent and social autonomous agents. Indeed, computer games offer a fitting subject for serious academic study, undergraduate education, and graduate student and faculty research. Creating and efficiently rendering these environments touches on every topic in a computer science curriculum. The "Teaching Game Design " sidebar describes the benefits and challenges of developing computer game design courses, an increasingly popular field of study

summary	The quality of the built environment depends critically on the concept of sustainability and, in particular, on designs which are energy efficient and environmentally friendly. This paper gives an account of the successful application of computer-based simulations of the physical environment made available to architects through an Energy Design Advice Scheme. It goes on to indicate how emerging multi-media technology can be used to provide an explanation, particularly to those who are technically unsophisticated, of the complexity of the way in which design decisions impact upon the energy efficiency and environmental friendliness of buildings.
