title	Image and Shape: Two Distinct Approaches
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 410-415
summary	This paper is the result of two researches done at the district of Campeche, Florianópolis, by the Grupo PET/ARQ/UFSC/CAPES. Different aspects and conceptual approaches were used to study the spatial attributes of this district located in the Southern part of Santa Catarina Island. The readings and analysis of two researches were based on graphic pistures builded with the use of Corel 7.0 e AutoCadR14. The first research – "Urban Development in the Island of Santa Catarina: Public Space Study"- examined the urban structures of Campeche based on the Spatial Syntax Theory developed by Hillier and Hanson (1984) that relates form and social appropriation of public spaces. The second research – "Topoceptive Characterisation of Campeche: The Image of a Locality in Expansion in the Island of Santa Catarina" -, based on the methodology developed by Kohlsdorf (1996) and also on the visual analysis proposed by Lynch (1960), identified characteristics of this locality with the specific goal of selecting attributes that contributed to the ideas of the place its population held. The paper consists of an initial exercise of linking these two methods in order to test the complementarity of their analytical tools. Exemplifying the analytical procedures undertaken in the two approaches, the readings done - global (of the locality as a whole) and partial (from parts of the settlement) - are presented and compared.

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

title	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	Virtual Tour Through Modern Architecture in Conception
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 475-477
summary	This paper describes the development of a project that was selected and sponsoured by the Regional Competition FONDART 1998 (Funds for the Development of Arts of the Regional Secretary of Education) that follows the aim of cultural diffusion. Towards the middle of the 30s, the city of Concepción developed an architecture distinctly colonial, neoclassical and eclectic. An earthquake in 1939 abruptly interrupted this scene, destroying the enterity of its most important buildings. The reconstruction of the city followed the manifestoes of Modern Architecture, consolidating the urban importance of buildings such us the Law Courts, the Railway Station and the Regional Government, that emerged as the new architectural and cultural heritage of the city. The project consisted on the modeling of eleven buildings of the modern architectural heritage, and on the generation of 42 virtual tours through the buildings that were finally edited on a 16' video. This video allows the spectator to make a virtual tour through the original modern heritage of the city, nowadays demolished, altered, and sometimes, even forgotten. This project pretends to widen the ways of comprehension of our cultural identity by using computer modelling and animation as a tool for the conservation of the architectural heritage; and creating a record that can be used as a reference and as an instrument of cultural difussion.

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

source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 347-348
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	Proceedings of VRML 99 Fourth Symposium on the Virtual Reality Modeling language, The Association for Computing Machinery, Inc. New York, pp. 133-140
summary	This paper describes a system for authoring and executing shared virtual worlds within existing VRML97 viewers such as Cosmo Player. As VRML97 does not contain any direct support for the construction of virtual worlds containing multiple users extensions are presented to provide support for shared behaviours, avatars and objects that can be manipulated and carried by participants in the world; these extensions are pre-processed into standard VRML97 and Java. A system infrastructure is described which allows worlds to be authored and executed within the context of the World Wide Web and the MBone.

title	Patterns for Volumetric Recognition - Guidelines for the Creation of 3D-Models
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 171-175
summary	This piece proposes new strategies and pedagogic methodologies applied to the recognition and study of the subjacent measurements of the architectural projects to be created. This proposal is the product of pedagogic experience, which stems from this instructional team of the department of tri-dimensional models of electronic models. This program constitutes an elective track for the architectural major at the college of architecture, design, and urbanism of the University of Buenos Aires and housed at the CAO center. One of the requirements that the students must complete, after doing research and analytical experimentation through the knowledge that they acquired through this course, is to practice the attained skills through exercises proposed by the department in this case, the student would be required to virtually rebuild a paradigmatic architectonic piece of several sample architects. Usually at this point, students experience some difficulties when they analyze the existing documents on the plants, views, picture, details, texts, etc., That they have obtained from magazines, books, and other sources. Afterwards, when they digitally begin to generate basic measurements of the architectural work to be modeled, they realize that there are great limitations in the comprehension of the tri-dimensional understanding of the work. This issue has brought us to investigate and develop proposals of volumetric understanding of patterns through examples of work already analyzed and digitalized tri-dimensionally in the department. Through a careful study of the existent documentation for that particular work, it is evaluated which would be the paths and basis to adopt through utilizing alternative technologies to arrive at a clear reconstruction of the projected architectural work, the study gets completed by implementing the proposal at the internet site http://www.datarq.fadu.uba.ar/catedra/dorcas

title	Evolutionary Design Tools for Mass-Customisation
source	III Congreso Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings] Montevideo (Uruguay) September 29th - October 1st 1999, pp. 152-156
summary	This paper describes an instance of the author’s ongoing research in the field of Generative Design. The work is based on the premise that computer-aided design (CAD) should evolve beyond its current limitation of one-way interaction, and become a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customised designs which exhibit common features. The understanding of fundamental shape-forming processes in nature inspires us to move beyond the existing CAD paradigms and re-examine the way we can benefit from the computers in design. We can use this knowledge to create a new generation of computer-based design tools which use evolutionary search algorithms to generate create a common family of individual designs optimised according to particular criteria, while supporting our design intuition. The author explores this idea by illustrating a research project between the Hong Kong Polytechnic University and Deakin University (Australia). The project implements a multi-user oriented design tool for evolutionary design, which was tailored to produce a simple object such as door handle. The paper first gives a short historical and philosophical to the work, then describes the technical and algorithmic requirements, and implementation of the system. It concludes by describing an experiment in which the system was used on a "live" test group of people to generate individual, mass-customised designs.

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

title	Is it Possible to Design in Full Scale? A CAD Tool in a Synthetic Environment
doi	https://doi.org/10.52842/conf.caadria.1999.043
source	CAADRIA '99 [Proceedings of The Fourth Conference on Computer Aided Architectural Design Research in Asia / ISBN 7-5439-1233-3] Shanghai (China) 5-7 May 1999, pp. 43-52
summary	This project developed a Virtual Architectural Design Tool (VADeT) executed in the C2 Virtual Reality (VR) space. C2 is a synthetic CAVE environment providing a full-scale setting for image projection and perception. Applying this tool for design offers four advantages over other CAD systems. First, it enables navigation performing in full scale to create the sense of immersion and reflection of the seeing-as. Second, it allows the creation, modification, and editing of three-dimensional objects in a virtual space. Third, designs can be modified and viewed simultaneously inside or outside of the generated model to obtain the best design products. Fourth, the entire design process can be recorded and played back. Collectively, this tool serves the purposes of: (1) a three-dimensional sketching tool for manipulating 3-D objects, (2) a design study tool for transparently displaying the design processes, and (3) a design teaching tool to demonstrate the processes by which designers do design. Thus, design in a full-scale representation not only is possible but also is a new and unconventional mode that will heavily influence design thinking.

summary	This research project developed an electronic library of significant buildings chosen to represent seven selected periods of Western architectural history: Egyptian (Mortuary temple of Queen Hatshepsut), Greek (Parthenon), Roman (Pantheon), Romanesque (Speyer Cathedral), Gothic (Notre Dame Cathedral), Renaissance (Tempietto), and Modern (Des Moines Art Center). All buildings were reconstructed in their original or intended forms based on plans, drawings, photographs, and historical texts. Two products were generated by this project: (1) materials to be displayed on the World Wide Web, including rendered still images for perception, movies for a visual guide, and Virtual Reality Modeling Language (VRML) models for user navigation; and (2) virtual reality (VR) models to be displayed in the C2 (an improved version of the Cave Automatic Virtual Environment or CAVE facility). The benefits of these VR models displayed on the Web and in the C2 are their easy accessibility at any time from various geographic locations and the immersive experience that enhances viewersÌ understanding of the effects of spatial proportions on form and of colors on materials.

doi	https://doi.org/10.52842/conf.acadia.1999.198
source	Media and Design Process [ACADIA ‘99 / ISBN 1-880250-08-X] Salt Lake City 29-31 October 1999, pp. 198-210
summary	Grammar based production systems are considered potentially powerful design tools by their ability to generate sets of designs adhering to user specified constraints. However, development of such tools has been slow, partly because of the lack of good interaction between user and system. This paper describes modes of user interaction and control possible with grammar based design systems and presents issues to be examined in the development of models that represent the locus of interactions possible with such systems. The examination of existing grammar based systems provides empirical evidence to support the validity of such models.
