title A New Methodology to Develop Hypermedia Systems for Architecture History
doi https://doi.org/10.52842/conf.ecaade.1995.043
source Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 43-52
summary This paper illustrates a research project concerning the analysis of architectural works through a comparative study based on hypermedia tools; by exploring the hypermedia, users can find the main subjects relative to the "method " of architectural planning. The use of multimedia in architecture allows the integration in a single system of different types of information which are necessary for the description of a work. texts, designs, photos and sounds. In addition, the hypertext information structure allows the direct intervention on analyzed projects, by pointing out the more important themes and their relationships. Users have the opportunity to immerse themselves in hypermedia and choose the subject to navigate through on each occasion. Our research project aims at developing a prototype concerning two architects. I.L.Kahn and F.L. Wright. The development methodology is based on the key role played by the components of architectonic works, thus allowing users to compare them in a simple and correct way. The methodology used in this work can be extended to other architects or periods, by simply changing the possibility of navigation, i.e. by changing the reading keys.

doi https://doi.org/10.52842/conf.ecaade.1995.003

summary IPER (hypertext for the knowledge of building patrimony) is the result of a research developed with C.N.R. (National Research Institute). The aim of IPER is to provide the knowledge, the description and the management of one or more historical buildings for public or private institutions. IPER allowed us to improve our methodology of building analysis, covering various disciplinary fields, in two different systems. (1.) the first one, synthetic and suitable for a group of historical buildings, (2.) the second one, complex and particularly made for monumental buildings. // This experience is related to the new regulation of teaching architecture in Italy made in 1993. The main novelty is the introduction of the laboratories with the contemporary presence of two or three teachers of different disciplines, working together with the students on the same project with different approaches. This opportunity allowed us to introduce the "knowledge engineer" as a teacher in the laboratory of building technology. IPER is given to the students with the aim of experimenting and solving the theoretical and practical difficulties that students of different years may encounter in the knowledge and representation of buildings and in the organisation of all the data from the case study.

summary In recent years two technologies, hypertext and expert systems, developed independently each other, drawn researcher´s attention since they seemed good tools to represent the knowledge and the reasoning process performed by human beings. These two technologies, until recently, had not too much intersection between them notwithstanding both were involved in representing the knowledge of experts of some domains and the domains itself. Also in the architecture field some expert systems and many hypertext products have been developed. Starting from some applications developed by our research team, in terms of expert systems and hypertext, we try here to give some suggestions about the possible interactions and the complementary use we may done of them.

summary The rapid development of the potentialities of multimedia imposes a reflection about its use in teaching architecture. Multimedia is multifaceted and each facet deserves a particular attention inasmuch as it can change the traditional approach to learning. A direct experience of an architectural work can be simulated with a impact far stronger than an experience trough photographs, drawings and books can do. But, as every positive fact can have in certain cases also some negative consequences. the intensity of the participation to an experience structured by someone else can leave less space to a personal approach to the object of the presentation. The same problem is posed if we consider the structure of an hypertext. The essence of the hypertext lies in the net of relationships between very different kinds of documents that it is able to manage in order to express the complexity of its theme. But who has to create the net, the teacher choosing the relationship that he thinks important or the learner to build a personal image of the hypertext matter. It is an old question about the two faces of teaching: transmitting knowledge or giving the learner the instruments to build by oneself his store of knowledge. Easy and trivial answer that both approaches can be useful. The accomplishment of a multimedial sequence of average complexity requires at present a lot of time. Hence, to be convenient, it is to be used many times, then by many students. The effectiveness of the tool partly depends on the rapidity with which it can be constructed. Speeding it up would allow to use this kind of tools with the same easiness than mare traditional means of representation. Besides those general considerations a check is to do on the peculiarities, if any, of the use of multimedia in the different disciplines of the formative curriculum of an architect. This is theme of our thirteenth conference. The programme has been articulated into sessions, dealing separately with history teaching, design teaching and research. Of course the sessions dealing with design are more numerous than the other, since design is the axis of teaching architecture. The presented paper cover a large arc of arguments, dealing with many facets of the proposed themes with plenty of examples and documentation on practical experiences. constituting a corpus of great usefulness for any operator in the field of architectural teaching.

summary Founded in 1995 LAB[au], laboratory for architecture and urbanism, links theoretic research LAB[a+u] to concrete works of conception and realisations LA.BAU. LAB[au] elaborates a “hyperdesign” investigating the implications of new technologies of communication and computation in spatiotemporal and social processes and their forms of representation as architecture and urbanism. The transposition of the hypertext model to architectural and urban concepts question the mutation of the spatial and semantic construct of space. The definition of architecture as a code is based on “glocal” systems according to the processes of computation and communication.

title StereoCAD: Three Dimensional Representation

summary Concepts of stereoscopic vision have been around for more than two thousand years. Despite this long history, its application to the field to architecture and design seems relatively unexplored. Synthesis of two technologies, the stereoscope and the computer, was the focus of the present study. The goal of the research was to determine if computer-generated stereoscopic pairs hold value for architectural design. Using readily available computer technology (Apple Macintosh) the research team modelled and rendered an existing project to verify the degree of correlation between the physical construct, the computer 3D model and resultant correlation between the physical construct, the computer 3D model and resultant rendered stereo-paired representation. The experiments performed in this study have shown that producing stereo-paired images that highly correlate to reality is possible using technology that is readily available in the marketplace. Both the technology required to produce (i.e., personal computer and modelling/rendering software) and view (i.e., modified stereoscope) the images is unimposing. Both devices can easily fit in a studio or a boardroom and together can be utilized effectively to permit designers, clients and end-users to experience proposed spaces and projects. Furthermore, these technologies are familiar (clients and end-users have already experienced them in other applications and settings) and assume a fraction of the cost of more dynamic, immersive virtual reality systems. Working from this base, limitations of the process as well as future applications of computer-generated stereoscopic images are identified.

title On the Conceptual Feasibility of a CAAD-CAAI Integrated Decision Support System: A Computer Aided Environment for Technical Decision Making in Architecture
source Delft University of Technology
summary This document addresses two questions: What are the ultimate means of design support we can offer to the architect, and how can we devise them? We are not the first ones to address these questions, neither the first ones to point our finger in the direction of Decision Support Systems for such purposes. Nevertheless, we may be among those scholars that understanding 'Decision Support" in terms of "Learning Support", are willing to explore the implications that such an understanding assumes for the concept of Decision Support Systems. Our exploration in such regards has shown us that knowledge application and knowledge acquisition cycles describe a continuum, and that such cycles, encapsulated in our "Practice Based Learning" and "Continuing Professional Development" dynamics are present in both our instructional and professional environments. From such a perspective, our scope regarding feasible Decision Support Systems is not restricted to the use of CAAD instrumental resources, but expanded into a context of CAAD-CAAI integration. Throughout this document we conceive a system that blends CAAD and CAAI resources looking forward to the creation of a Support Environment that seeks to motivate a reflective attitude during design, in such a way, upgrade our capability for acquiring as well as applying knowledge in design. In instrumental terms, this document explains how mainstream CAAD developments in the field of "Intelligent Front End Technology" and CAAI developments in the field of "Knowledge-based Curricular Networks" can complement each other in the establishment of a Decision Support System of trans-environmental relevancy. As an application framework for the concept and instrumental base described above, this document presents an image of the kind of decision-making model that it will intend to support, the kind of task support model it will look forward to implement, and the kind of general instrumental layout it will require. On the basis of such an instrumental layout, the system that is hereby outlined can be regarded as a "CAAD-CAAI Integrated", "Intelligent", and "User-Oriented" Interface System.

title Patriarch: A Hypermedia Environment for the Support of Architectural Design
doi https://doi.org/10.52842/conf.ecaade.1995.187
source Multimedia and Architectural Disciplines [Proceedings of the 13th European Conference on Education in Computer Aided Architectural Design in Europe / ISBN 0-9523687-1-4] Palermo (Italy) 16-18 November 1995, pp. 187-198
summary This paper reports on current research in the field of architectural design and knowledge- based systems, through the conception and implementation of two software tools operating as a part of an integrated hypermedia environment denominated PatriArch. Main concern of this set of tools operating in PatriArch is the support of design since the very beginning, in that phase of not yet correctly explored or interpretated constraints and of scarcely specified goals, in which an initial solution model - provisionally composed of fragments of supposed fitting ideas - for the design theme has to take place. The creative activity of the designer is assumed as an 'intentional planning activity' that represents the acquired level of knowledge of the network of connections defining the nature, function, shape in the space etc. of the increasingly integrated solution-model: the final design will be an evolution of this - and other competitive and concurrent - models. PatriArch is meant to be the environment containing and allowing the representation of this evolution through its ability of linking the fragments of designers' knowledge, supported by an integrated relational data base: Sysinfo. These works were conceived inside an educational software development program for architecture students.

summary Given that there is a need to shade a window from the summer sun and also a need to expose it to the winter sun, this article describes an algorithm to design automatically a geometric construct that satisfies both requirements. The construct obtained represents the minimum solution to the simultaneous requirements. The window may be described by an arbitrary convex polygon and it may be oriented in any direction and it may be placed at any chosen latitude. The algorithm consists of two sequential steps: first to find a winter solar funnel surface; and the second to clip the surface subject to the summer shading conditions. The article introduces the design problem, illustrates the results through two examples, outlines the logic of the algorithm and includes the derivation of the mathematical relations required to implement the algorithm. This work is part of the MUSES project, which is a long term research effort to integrate Energy Consciousness with Computer Graphics in Architectural Design.

summary The structure of a set of documents allow for navigation inside single texts. Yet it is often also an obstacle to comparability between different parts and concepts. Even document formatting is only a partial answer to the problem, since it fails to develop the matter of relationships between enunciation and results. It was need to retrieve information about the scientific findings made by Research Units (Operating Units) during the first three year period of the "Progetto Finalizzato Edilizia" (PFEd) for assessment and transfer purposes which led us to design and develop a system to facilitate the retrieval of the relevant information. We chose the building sector for this application because of its relative lack of previous experience of this type, the variety and complexity of documentation available and, last but not least, the general underestimation of research topics and results vis-à-vis the development of the sector. By making the suggestion and information inherent in its findings more available, in terms of method and ambit, as well as more explicit, the research has already achieved a significant result. In view of the prototype character of the experiment, the information will probably be adopted to produce an hypertext on the final results.

summary The relationship between the media and architectural design can be an important factor and can influence the design outcome. However, the nature, direction and magnitude of this relationship are unknown. Consequently, there have been many speculative claims about this relationship and almost none of them are supported with empirical research studies. In order to investigate these claims and to provide a testable framework for their potential contributions to architectural education, this study aims to explore the effects of media on architectural design. During 1995-1997, a total of 90 students enrolling in First Year Design Studio and Introduction to Computing classes at Georgia Tech participated in the study. A set of quantitative measures was developed to assess the differences between the two media and the effects on the architectural design. The results suggested that media influenced certain aspects of students’ designs. It is concluded that there is a strong relationship between the media and architectural design. The type of media not only changes some quantifiable design parameters but also affects the quality of design.

title High tractive power wall-climbing robot
source Automation in Construction 4 (3) (1995) pp. 213-224
summary There are a lot of tasks in building construction and maintenance which demand either the carriage of heavy technological equipment along vertical and sloping surfaces and/or provision for force technological operations on such surfaces For example, surface cleaning or grinding by automatic equipment, the mounting of expansion bolts and anchors by drilling or by driving in. Additionally surface inspection by heavy measuring devices and the painting of big construction areas are difficult and expensive to perform manually. It is therefore expedient to apply climbing robots to automate these tractive power operations. The climbing robot was developed for such purposes. The design of the robot with increased load capacity and improved gripper system was carefully considered. The robot has a video camera for orientation and for the monitoring of processes. A sensor-based computer control system is used. This paper contains a brief overview of the technical parameters and experimental characteristics of the robot's transport module, control system with video camera unit, and the different schemes of the robot's application.

title Childishly Honest Associate of the Trickery
source CAD Space [Proceedings of the III International Conference Computer in Architectural Design] Bialystock 27-29 April 1995, pp. 209-219
summary Perspective is a method of presentation of 3- dimensional space on the 2-dimensional surface. It can only approximately express the complexity of the authentic perception of reality. During the centuries canons of presentation varied in different epochs. It is quite possible that conventions of presentation considered today as exact expressions of reality may seem for the future generations as untrue as the ancient Egypt paintings seem for us. Our mind plays the major role in all kinds of presentation. During the whole life we learn to perceive the surrounding reality. We have formed also ability to ,see" the perspective. The linear perspective is not so easy in perception without factors of colour and light. These factors play a very important role in perception of the distance. The perception of perspective is not always unmistakable. Introduction of light and shadow is one of the measures to limit the ambiguity. Objects shown in perspective with appropriately chosen colouring and light-and-shade effects reveal impression of the distance inside the flat picture. Illusions of perspective are most astonishing when one can assume deep-rooted expectations and suppositions of the addressee. The computer monitor, like the picture, has only one plane on which our project can be presented. The major feature of architecture programs is both the possibility of creating various architecture spaces and the possibility to examine how (in our opinion) the created space would affect the addressee. By means of computer programs we are able to generate drawings and objects of two kinds: first - being the ideal projection of reality (at least in the same measure as the photograph), and the second - being the total negation of perspective rules. By means of CAD programs enabling 3-dimensional job we can check how all sorts of perspective tricks and artifices affect our imagination. The program cooperates with us trying to cheat the imperfect sense of sight. The trickeries can be of various type, starting from play of lights, through the elements changing the perception of perspective, and terminating with objects totally negating the rules of sound construction of solids. The knowledge contained in these programs is an encyclopaedic recapitulation of all sorts of achievements in the field of perspective and application of colour and light effects. All that remains to the users is to exploit this tremendous variety of capabilities.

title What can real-time positioning do for construction?
source Automation in Construction 5 (2) (1996) pp. 79-89
summary New technologies are now available that can rapidly measure three-dimensional coordinates of objects. The integration of these fast 3-D Real-time Position Measurement (D-RtPM) devices and CAD (3D-RtPM/CAD) technologies can be viewed as a better tool for surveyors or as a means to change the most fundamental concepts of the construction industry. 3D-RtPM/CAD is a better surveying tool; however, 3D-RtPM/CAD as the basis for fundamental change within the construction industry is the issue. There are several potential technologies that can provide real-time position measurement. This paper will limit presentation to two of these. The first is based on recent developments in Global Positioning Systems. The second is a new laser-based product, OdysseyTM (Odyssey is a trademark of Spatial Positioning Systems, Inc.). Odyssey received the NOVA award in March, 1995 because of its recognized performance enhancement to the construction industry. These positioning systems provide the capability for equipment and crafts people to view the project from a graphical representation in which they see their position interactively updated. Potential benefits to the construction industry are presented. The research needed achieving maximum benefits of these systems is also presented.

title Computing And Manipulation In Design - A Pedagogical Experience Using Symmetry
source SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary The concept of symmetry has been usually restricted to bilateral symmetry, though in an extended sense it refers to any isometric transformation that maintains a certain shape invariant. Groups of operations such as translation, rotation, reflection and combinations of these originate patterns classified by modern mathematics as point groups, friezes and wallpapers (March and Steadman, 1974). This extended notion represents a tool for the recognition and reproduction of patterns, a primal aspect of the perception, comprehension and description of everything that we see. Another aspect of this process is the perception of shapes, primary and emergent. Primary shapes are the ones explicitly represented and emergent shapes are the ones implicit in the others (Gero and Yan, 1994). Some groups of shapes known as Semantic Shapes are especially meaningful in architecture, expressing visual features so as symmetry, rhythm, movement and balance. The extended understanding of the concept of symmetry might improve the development of cognitive abilities concerning the creation, recognition and meaning of forms and shapes, aspects of visual reasoning involved in the design process. This paper discusses the development of a pedagogical experience concerned with the application of the concept of symmetry in the creative generation of forms using computational tools and manipulation. The experience has been carried out since 1995 with 3rd year architectural design students. For the exploration of compositions based on symmetry operations with computational support we followed a method developed by Celani (2003) comprising the automatic generation and update of symmetry patterns using AutoCAD. The exercises with computational support were combined with other different exercises in each semester. The first approach combined the creation of two-dimensional patterns to their application and to their modeling into three-dimensions. The second approach combined the work with computational support with work with physical models and mirrors and the analysis of the created patterns. And the third approach combined the computational tasks with work with two-dimensional physical shapes and mirrors. The student’s work was analyzed under aspects such as Discretion/ Continuity –the creation of isolated groups of shapes or continuous overlapped patterns; Generation of Meta-Shapes –the emergence of new shapes from the geometrical relation between the generative shape and the structure of the symmetrical arrangement; Modes of Representation –the visual aspects of the generative shape such as color and shading; Visual Reasoning –the derivation of 3D compositions from 2D patterns by their progressive analysis and recognition; Conscious Interaction –the simultaneous creation and analysis of symmetry compositions, whether with computational support or with physical shapes and mirrors. The combined work with computational support and with physical models and mirrors enhanced the students understanding on the extended concept of symmetry. The conscious creation and analysis of the patterns also stimulated the student’s understanding over the different semantic possibilities involved in the exploration of forms and shapes in two or three dimensions. The method allowed the development of both syntactic and semantic aspects of visual reasoning, enhancing the students’ visual repertoire. This constitutes an important strategy in the building of the cognitive abilities used in the architectural design process.

summary This paper describes how Hypermedia can be used as unifying tool, marrying together many strands of work related to architectural design and CAD. The project which we describe was undertaken with fourth year students at the University of Liverpool and is entitled the Electronic City. It is founded on the premise of assembling a Hypermedia package which describes the city and its architecture to a lay person. There are two strands to the project, the Hypermedia strand and a graphics/CAD strand. At the end the task was then to stitch the strands together to produce a common, coherent Hypermedia package. At the end of the project we expect that the students will have developed skills and an appreciation of: (-) the architecture and history of the city (-) the design of Hypermedia interfaces (-) the design of Information structures (-) three dimensional modelling and rendering
