title Gothic Cathedral in the Virtual Reality
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 43-56
summary Everyone who once visited Beauvais, small town placed 100 km from Paris, certainly asked himself: "how would have this highest gothic cathedral, that was started here, looked like if it had been completed?". I attempted to answer this question in my diploma work in 1994. However, the task wouldn't be done without power of contemporary computers. They made it possible to create the entire three-dimensional model of this magnificent building in the virtual reality. Cathedral Saint-Pierre in Beauvais, which was started in 1225, partly collapsed in 1284 and 1573. Finally, in 1600, when only choir and transept were finished, the works had been interrupted. The height of this highest gothic interior in the world is 48.5m. To my disposition I had the drawings of plan and cross- section of the existing part of the building, photographic specification and detailed description of the construction of the cathedral. I used PC 486DX/33, 16 MB RAM, HD 170 MB and software: Autodesk AutoCAD r.12 and AccuRender r.1.10. The work was divided into three stages. The first one was "building" the model of existing part of the cathedral in the threedimensional CAD-space. The next one was trying "to finish" the temple based on theoretical reflections and comparative analyses of existing French gothic cathedrals. The last stage included the performance of the series of pseudorealistic pictures showing the "finished" cathedral in Beauvais from the outside, inside and with illumination by night.

title Street-scape and Way-finding Performance
source The Future of Endoscopy [Proceedings of the 2nd European Architectural Endoscopy Association Conference / ISBN 3-85437-114-4]
summary In this study, it was hypothesized that people’s performance of way-finding depends on the characteristics of street-scapes, i.e., the more visual information exists the easier people find their own ways. This relationship was investigated by an experiment using an environmental simulator and analysis of the subject’s behavioral data recorded by the simulation system. Three scale models (1/150) of identical maze patterns (300m x 300m) which have different street-scapes were created and set in the simulator, in which an endoscope connected to CCD color TV camera controlled by a system operated by a personal computer. Three types of streets are: (1) having no characteristics with monotonous surface, (2) having characteristics on each corner with different buildings, (3) having characteristics along the streets with trees, columns or fences. The simulator allows a subject to move through the scale models and looking around, using a “joy-stick“ for viewing the scene as projected on 100-inch CCTV screen. The control system of the simulator records all signals generated by the “joy-stick“ every 0.01 second, and thus exact position within the model space and the viewing direction at given moment can be stored in the computer memory, which can be used to analyze the subject’s behavior. The task of a subject was to find the way which was previously shown by the screen. Three male and three female subjects for each of three street types, for a total of eighteen subjects participated in the experiment. An analysis of the trace of movements and viewing directions generally supported the hypothesis that the street with visual characteristics were easier to memorize the route although there was a large difference in performance among subjects. It was also noted that there were three different strategies of way-finding according to the subject: one group of subjects seemed to rely on well structured knowledge of the route, i.e., the cognitive map, and the other group seemed to rely on incoming visual information of the changing scenes, and the last group seemed to find the way using both the cognitive map and visual information depending on the situations.

title Development of a Portable Virtual-Reality System for Disaster Education
source Proceedings of the 8th European Architectural Endoscopy Association Conference
summary Given that the probability of a catastrophic earthquake occurring is quite high in Japan compared to other countries; major cities like Tokyo operate many disaster-education facilities for informing citizens about earthquake preparedness. Since an earthquake occurs suddenly with almost no time to react, daily preparation plays a greater role in reducing damage than for other types of disasters. In fact, statistics from the Kobe earthquake in 1995 show the largest cause of injury to have been falling furniture, something that could have been prevented with proper precautionary measures.

title An automated environment for soils- and terrain-dependent applications
source Automation in Construction 4 (2) (1995) pp. 139-146
summary This paper explains the development of an integrated information environment that is designed specifically for applications dependent on information related to soil types and terrain of the project site. This covers a wide variety of applications such as shallow and deep foundations, trenching, earthmoving and tunneling. The design of this environment takes into consideration the typical requirements of the project team with an emphasis on integrating requirements for both design and construction. The environment reported here is comprised of three main modules, a relational database for the storage and display of soil borelog information, a geographic information system that displays the geographical locations of soil studies, and a module that is used to develop a three-dimensional profile of the soil layers between any number of borelogs. The user may also develop cross sections of soil layers in any direction. This paper reports on the hardware and software used and concludes with a discussion of future extensions to the system.

title Supporting Collaborative Design with Representations for Mutual Understanding
source ACM CHI
summary This paper describes a research effort to investigate cross-cultural collaboration in software development. The work is based on a model of collaborative design that calls for stakeholders (including developers and end-users) to iteratively construct an understanding of design problems and potential solutions through the construction and refinement of design representations. The Evolving Artifact (EVA) software design environment has been implemented to support this process. EVA has been used in a development project in a regional telephone company. A case study of this project will be analyzed to yield guidelines and design principles for constructing representations for mutual understanding.

title Design Case Bases: Graphic Knowledge Bases for the Design Workspace
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 555-565
summary Cases in the domain of architecture and engineering are commonly stored and presented as graphical representations in the form of drawings. The way creative designers fit and adapt graphical representations through drawing and re-drawing is still one of the least understood phenomena in design. Modeling stich processes appears to be a key to graphic knowledge base integration in CAAD environments. The paper reports on a new approach to modeling design adaptation in a graphical environment. This approach is based upon a theory of creativity, the Representation - Re-representation Hypothesis which is here employed in the formalization of design adaptation. A 'multi-layer re-representational model' which assists in the adaptation of design drawings is developed and presented. The model is based on the transformation of chunks of knowledge in design cases into explicit re-representational structures which can support creative design in a graphic environment. This model is utilized in our current work in development of a prototype graphical case-based CAAD system.

title Integration of Architectural Education in Teaching Interactive Media Design - A Course for Space Composition
source Architectural Information Management [19th eCAADe Conference Proceedings / ISBN 0-9523687-8-1] Helsinki (Finland) 29-31 August 2001, pp. 245-248
summary In accordance with our design knowledge, the users’ expectations and the level of the technology reached, show us that interactive media design is not only an interactive environment which depends on two dimensional typographic composition any more. Spatial data has an important role in the formation of interactive media design (TUFTE 1995 p.38). From this point of view, the main factors of this issue are: (1) design of the storyboards, especially for gamedesign, that are made up of spatial perception, (2) the spatial organisations in which info-kiosks take place in public environment, (3) the relation between the screen and the organisation of space in interactive exhibition design. // When we consider the matter above, we understand that throughout the process of the curriculum of interactive media design for undergraduate education, only the traditional communication design and programming education is not sufficient enough, but architectural education must also take a part of this education in some degree. In this paper, as the theme of the considerations above, it is examined what kind of basic problems is to be faced in the integration of architectural education to that of the interactive media design and also the solution propositions formed for these problems.

title Geometric programming: A programming approach to geometric design
source ACM Transactions on Graphics
summary This article presents a functional programming approach to geometric design with embedded polyhedral complexes. Its main goals are to show the expressive power of the language as well as its usefulness for geometric design. The language, named PLASM (the Programming LAnguage for Solid Modeling), introduces a very high level approach to "constructive" or "generative" modeling. Geometrical objects are generated by evaluating some suitable language expressions. Because generating expressions can be easily combined, the language also extends the standard variational geometry approach by supporting classes of geometric objects with varying topology and shape. The design language PLASM can be roughly considered as a geometry-oriented extension of a subset of the functional language FL. The language takes a dimension-independent approach to geometry representation and algorithms. In particular it implements an algebraic calculus over embedded polyhedra of any dimension. The generated objects are always geometrically consistent because the validity of geometry is guaranteed at a syntactical level. Such an approach allows one to use a representation scheme which is weaker than those usually adopted in solid modelers, thus encompassing a broader geometric domain, which contains solids, surfaces, and wire-frames, as well as higher-dimensional objects.

title Prototype Shape Modeling with a Design Language
source Sixth International Conference on Computer-Aided Architectural Design Futures [ISBN 9971-62-423-0] Singapore, 24-26 September 1995, pp. 59-75
summary A programming approach to the rapid prototyping of architectural design is discussed in this paper. This is done with particular reference to the early steps of design development, where a number of preliminary design alternatives should be generated and evaluated. At this purpose we show that the generation of the 3D shape of each design alternative can be automated starting from the 2D layout of plans, sections and elevations. Each such geometric object can be symbolically defined with few lines of code using design variables and constraint operators. The 3D models generated by evaluation of program scripts may then be used as input to standard engineering evaluation methods concerning costs, heat exchanges and structural behaviour.

title Roof Modeling Using Architectural Semantics Paradigm

summary This paper presents an approach to developing the computer aided architectural design systems investigating architectural semantics paradigm and void modeling representation as a method. A prototypical system called FRED(Facile Roof Editor & Designer) was developed incorporating structural logic and characteristics of roof in its basic representation and its operational behavior constrained by distinct attributes of a roof. Design of Hip, Pitch, Multi-level, and Flat roofs in Solid and Shell forms was made possible by extracting from an existing building or creating them as independent entities. The implementation successfully demonstrates that incorporating architectural semantics in the basic representation of a CAD system allows architects to create and test roof morphology fairly quickly, accurately, and fluidity for ideation.

title Function representation in geometric modeling: concepts, implementation and applications
source The Visual Computer, 11 (8) 429-446
summary Geometric modeling using continuous real functions of several variables is discussed. Modeling concepts include sets of objects, operations and relations. An object is a closed point set of n-dimensional Euclidean space with a defining inequality f x x xn ( , ,..., ) 1 2 0 °Ÿ . Transformations of a defining function are described for the set-theoretic operations, blending, offsetting, bijective mapping, projection, Cartesian product and metamorphosis. Inclusion, point membership and intersection relations are described. In the implemented interactive modeling system, we use highlevel geometric language that provides extendibility of the modeling system by input symbolic descriptions of primitives, operations and predicates. This approach supports combinations of representational styles, including constructive geometry, sweeping, soft objects, voxel-based objects, deformable and other animated objects. Application examples of aesthetic design, collisions simulation, NC machining, range data processing, and 3D texture generation are given.

title Tornado Pavilion - Simplexity, almost nothing, but human expanded abilities

summary In the context of the fourth industrial revolution, not all regions have the same access to technology for project development. These technological limitations do not necessarily result in worst projects and, on the contrary, can stimulate creativity and human intervention to overcome these shortcomings. We report here the design of a small pavilion with scarce budget and an ambitious goal to qualify a space through tactical urbanism. We develop the project in a multidisciplinary partnership between academy and industry, designing, manufacturing and assembling Tornado Pavilion, a complex structure using combined HIGH-LOW technologies, combining visual programming with analog manufacture and assembly. The design strategy uses SIMPLEXITY with ruled surfaces strategy to achieve a complex geometry. Due to the lack of automated mechanical cutting or assembly, we used human expanded abilities for the construction; instead of a swarm of robots, we had a motivated and synchronized swarm of students. The pavilion became a reference for local population that adopted it. This process thus shows that less or almost nothing (Sola-Morales 1995), need not to be boring (Venturi 1966) but less can be much more (Kolarevic 2017).

source II Seminario Iberoamericano de Grafico Digital [SIGRADI Conference Proceedings / ISBN 978-97190-0-X] Mar del Plata (Argentina) 9-11 september 1998, pp. 192-197
summary Colonia del Sacramento (capital of Colonia department, in Uruguay) has been registered in the list of the Convention Heritage concerning the protection of worldwide cultural and natural heritage. The registration on this list (December 6th 1995) confirms the exceptional and universal value of a cultural or natural places which deserves protection for the whole humanity. The ancient Colonia del Sacramento founded in 1680 by Portugal, was a commercial and military site leading role of the historical controversy between Spain and Portugal. Main place of wars and treaties during a century, it keeps an urban design, unique in the area and valuable architectonical testimonies of different periods of this rich past, with a simple, popular profile. This work has been effected within the Clemente Estable Found 1996, which is promoted by National Council of Scientific and Technical Research (CONICYT). Through virtual reality techniques, a three-dimensional model of Colonia del Sacramento city was built as it was in its period of prosperity (around 1762). For the achievement of this digital maquette, a great deal of written and graphic information was compiled and processed. This information was organized in an inventory way (with numerous readings and searches). The inventory and the digital maquette were joined in a multimedia application (CD-ROM) which allows potential users to move through virtual city and friendly and interactively consult images, graphics and texts.

summary The paper presents a progress report on a project investigating the possible application of a framework for cooperative-activities of computer design agents in the conceptual phase of architectural design. A process leading to definition of the expected performances of design agents is desribed, and some possible applications illustrated. The framework includes not only the objective, but also, the "subjective" agents. It is expected that the framework would offer an insight into the intricacies of CAAD in an educational environment, and provide the exploration paths and an efficient production of alternative solutions in an office.

summary In this paper, we discuss the importance of computer based simulation tools for the education of architects and civil engineers. We present our efforts to develop a program for the simulation of structures (CASDET). CASDET forms a microworld for planar structures. The program enables students to compose structures and to experiment interactively the effects of different geometry and load configurations. It tries to identify the proposed structure and controls its stability. Upon request of the student, it also processes displacements, internal forces (moments, shear forces etc.) and reaction forces on supports. The students can then visualise the desired information by interacting directly with the structure or member(s) of interest (see fig.1). We present different methods, with which students can visualise the results of their actions and discuss their implications in the educational context.

summary A person is a wonderful creature. His high organization helps him not only to see and to hear the world around him, but to feel and understand, to condole and pity. A person is a sacramental creature too. His complex organization helps him to see day as light and darkness, as delivery and death, as delight and grief. Every human reaction has biological, physiological and sensitive components. That is why environment is able to call up physical an emotional associations. A human being can "see" sound and "hear" colours. All history of human culture shows that the art can affect man in different ways: unconscious effects, spontaneous associations, general symbolic or specific conventional meanings. That is why architecture can not only protect (a safeguarded aspect), but give knowledge ( an informational aspect) and set up mood (an emotional aspect). And that is why we speak about ambiguity of sense and about multiartistic works. Such as Skriabin's symphony 'Prometheus'. Two scores - musical and colouristic - are connected in this masterpiece. Let us look through two architectural disciplines—from this point of view. The programmes of these disciplines are examples of such embedment. Any architectural discipline demands computer graphics. Any architectural discipline demands multimedia aided teaching, because multimedia in computer designing is a result of human being's complexity and ambivalence.
