title Programming framework for architectural design ANAR+: Object oriented geometry
source T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 771- 785
summary From the recent advent of scripting tools integrated into commercial CAAD software and everyday design practice, the use of programming applied to an architectural design process becomes a necessary field of study. The presented research explores the use of programming as explorative and reflexive medium (Schön, 1983) through the development of a programming framework for architectural design. Based on Java, the ANAR+ library is a parametric geometry environment meant to be used as programming interface by designers. Form exploration strategies based on parametric variations depend on the internal logic description, a key role for form generation. In most commercial CAD software, geometric data structures are often predefined objects, thus constraining the form exploration, whereas digital architectural research and teaching are in need for an encompassing tool able to step beyond new software products limitations.

title Simulation of the Emergency Evacuation of Buildings in the Event of Fire
source Proceedings of the International Conference eCAADe [European Computer Aided Architectural Design Education] Brussels (Belgium) 1983, pp. II.10-II.22
summary The paper describes an application of CAAD techniques by Final Year architecture students using the computer program AIR-Q to dynamically simulate the emergency evacuation of people from a multi-storey department store. This is presented in the context of a fire emergency and reference made to the local Building Regulations which govern the size and location of fire exits. It is suggested that the technique not only provides students and designers with an easily assimilated understanding of the consequences of design decisions but also allows alternative design solutions to be quickly compared in a search for the optional design strategy. The exercise also demonstrates, to the students, the logic behind the rules contained in the Fire Regulations while demonstrating possible weaknesses and inadequacies of the empirical approach that these regulations are constrained to adopt.

title Computers in Architectural Education

summary Throughout Europe there is a rapidly growing volume of initiatives towards integrating computer aids within all aspects of education. In architectural education, the support offered by these initiatives presents a double-edged sword. On the one hand it is gratifying to see the work of almost two decades of CAAD research bearing fruit and the concepts gaining recognition by the profession. On the other hand the resulting pressures on the few individuals with the necessary knowledge to implement the teaching will stretch many to breaking point. Where resources are so limited it is crucial to clarify the needs and objectives and, thereby, more effectively direct resources. These needs will change over time and, in the world of computers, the means are also changing rapidly as hardware and software improves. This paper therefore outlines a scenario which I believe is relevant at this point in time but the background is constantly changing and I offer no apologies for any shift in emphasis since my last presentation of this topic in 1983.

summary One of the central issues in artificial intelligence involves learning -- the modification of behavior through the acquisition of knowledge. The way knowledge is represented impacts the way learning occurs and indeed may determine whether learning can occur at all. The issues of learning and representation have many potential interactions. The purpose of this paper is to illuminate representational problems that may not have occurred to researchers setting out to construct self-modifying systems, and to suggest some possible solution to these problems

title Integration of Solid Modeling and Data Base Management for CAD/CAM
source ACM IEEE Design Automation Conference Proceedings (20th : 1983 : Miami Beach, Florida). pp. 367-373 : ill
summary For the fast growing CAD/CAM technologies, geometric solid modeling plays one of the most important roles. In order to satisfy a variety of engineering applications, an integrated database management system based on solid modeling is highly desirable. In the proposed approach, a concise object representation scheme, Constructive Solid Geometry (CSG), is adopted as the basis for database design. The underlying generic relational model is found to be more adequate than the conventional relational model in characterizing the embedded data abstraction. A systematic method is devised for converting the CSG scheme into a generic model based on the BNF grammar which depicts the CSG scheme. A relational query language, SEQUEL, has been modified to define, control, and manipulate the flat relations which represent the highly structural generic model

title An Analysis and Algorithm for Polygon Clipping
source Communications of the ACM November, 1983. vol. 26: pp. 868-877 : ill. includes bibliography.
summary (This is one of the two standard algorithms for clipping. The other is the Sutherland-Hodgman reentrant algorithm). The process of polygon clipping is analyzed and the understanding gained thereby forms the foundation of a very direct algorithm. Each edge of the input polygon is considered to be a vector and is then extended to be a line of infinite extent. The boundary line segments of the clip window are extended in a similar fashion to become boundary lines. The intersection points of an extended edge with the boundary lines are identified as entry or exit points. It is observed that these entry and exit points can be used to characterize the visibility status of the edge. Not only might the edge have a visible segment, but it can also induce the inclusion in the output polygon of a vertex at a corner of the clip window called a turning vertex. To quantify the visibility conditions, the edge is written in parametric form. The possible contributions (including nil) that can be provided to the output polygon by a particular edge are established. This analysis is then embedded in an algorithm. An arbitrary example input polygon is given and the output of the algorithm is shown. The execution time for this example using this algorithm is measured to be half of what is required by the standard Sutherland-Hodgman reentrant polygon clipping algorithm

title Interactive virtual art
source SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 37-41
summary The interactivity presumes behavior action events exercised mutually between machines, between digital information and persons, between two or more persons, machines and digital information in real time. Nelson Max presented in Paris the first interactive landscape in 1983. The pioneer of scientific image was Ivan Sutherland, researcher of Massachusetts Institute of Technology (MIT). Another fundamental reference is Sonia Sheridan that invented a system where the user could modify the original image and visualize the result in real time. In Brazil, as well as in the outside, artists in assembly with scientists, see developing works computacionais with resorts of immersion and interatividade. Like this, in that search of new references, the text presents initially the main concepts about interactive virtual art and analyzes two important expositions: Emoção Art.Ficial 2.0 and Maior ou igual a 4D: computer art interactive.

title Efficiency of Model Endoscopic Simulation - An Experimental Research at the University of Stuttgart
source Endoscopy as a Tool in Architecture [Proceedings of the 1st European Architectural Endoscopy Association Conference / ISBN 951-722-069-3] Tampere (Finland), 25-28 August 1993, pp. 31-34
summary At the Institute of Urban Planning at the University of Stuttgart early experiments were made with the help of endoscopes in the late 1970’s. The intention was to find new instruments to visualize urban design projects. The first experiment included the use of a 16 mm film of a 1:170 scale model of the market place at Karlsruhe, including design alternatives (with trees, without trees etc). The film was shown to the Karlsruhe authorities, who had to make the decision about the alternatives. It was said, that the film gave a great help for the decision-making and a design proposition had never before been presented in such understandable way. In 1975-77, with the support of the Deutsche Forschungsgemeinschaft (German Research Foundation) an investigation was carried out into existing endoscopic simulation facilities, such as those in Wageningen, Lund and Berkeley. The resulting publication was mainly concerned with technical installations and their applications. However a key question remained: ”Can reality be simulated with endoscopy?” In 1979-82, in order to answer that question, at the Institute was carried out the most extensive research of the time, into the validity of endoscopic simulation. Of special importance was the inclusion of social scientists and psychologists from the University of Heidelberg and Mannheim. A report was produced in 1983. The research was concerned with the theory of model simulation, its ways of use and its users, and then the establishment of requirements for effective model simulation. For the main research work with models or simulation films, psychological tests were developed which enabled a tested person to give accurate responses or evidence without getting involved in alien technical terminology. It was also thought that the use of semantic differentials would make the work imprecise or arbitrary.

title What is eCAADe?
source The Third European Conference on CAD in the Education of Architecture [eCAADe Conference Proceedings] Helsinki (Finnland) 20-22 September 1984.
summary The main interest of the organisation is to improve the design, teaching. The design remains the core of the professional education, while computer science can support a better understanding of the design methods. Computers should amplify the human capabilities like engines allowed to carry higher forces, radio and television enabled communication over larger distances and computers today should aid the human intellectual activities, to gain a better insight in design methodology, to investigate the design process.Design research should study more extensively how buildings behave, the integration and interaction of different disciplines which contribute to the optimization of a design and the design criteria. Computers could increase the possibility to satisfy building regulations, to access and update information, to model the design process and to understand how decisions affect the building quality (functional and economical as well as formal aspects). More effort and money should be spent on this research. The organisation has been sponsored by the EEC for bringing CAAD (Computer Aided Architectural Design) educational material at the disposal of the design teachers. The Helsinki conference is the third European meeting (after Delft 1982 and Brussels 1983) which concentrates on information and experience exchange in CAAD-education and looks for common interests and collaboration. A specific joint study program works on typical audiovisual material and lecture notes, which will be updated according to teacher's needs. A demand has been done to implement an integrated CAAD package. eCAADe focuses to integrate computer approaches across country boundaries as well as across disciplinary boundaries, as to reach a higher quality of the design education.

summary Students currently in schools of architecture will be at the peak of their careers around the year 2000. The pressure on the schools to provide an education and training which will stand the student in good stead between now and then is considerable. In an increasing number of departments of architecture and building science, importance is being placed on the concept of modelling: i.e. the development and use of models of the operational behaviour and aesthetic character of design proposals which will allow appraisal of how real buildings will performing the real world.

title Supporting Reflection-in-Action in the Janus Design Environment
source The Electronic Design Studio: Architectural Knowledge and Media in the Computer Era [CAAD Futures ‘89 Conference Proceedings / ISBN 0-262-13254-0] Cambridge (Massachusetts / USA), 1989, pp. 247-259
summary We have developed a computer-based design aid called Janus, which is based on a model of computer-supported design that we think has significance for the future of architectural education. Janus utilizes a knowledge-based approach to link a graphic construction system to hypertext. This allows the computer to make useful comments on the solutions that students construct in a CAD-like environment. These comments contain information intended to make students think more carefully about what they are doing while they are doing it. In other words, Janus promotes what Donald Schon has called "reflection-inaction" (Schon, 1983). The Janus design environment is named for the Roman god with a pair of faces looking in opposite directions. In our case the faces correspond to complementary design activities we call construction and argumentation. Construction is the activity of graphically creating the form of the solution e.g., a building. Traditionally this has been done with tracing paper, pencils, and pens. Argumentation is the activity of reasoning about the problem and its solution. This includes such things as considering what to do next, what alternative courses of action are available, and which course of action to choose. Argumentation is mostly verbal but partly graphical.

title Justifying Designs
source Proceedings of the International Conference eCAADe [European Computer Aided Architectural Design Education] Brussels (Belgium) 1983, pp. 0.1-0.9
summary A distinction is made between non-justified (not 'unjustified') and justified designs. A good justification requires that a description of the solution space and a rule for selecting one solution should be given. The old but rarely used concept of the planning model is described and it is stressed that it is a useful aid when justifying design decisions. A simple example is presented to illustrate the method. It is pointed out that the use of computers can be helpful when dealing with large solution spaces, complicated evaluation rules and high demands on the quality of the justification. An increasing demand for design justification is observed, which may result in increased computer application. The hope is expressed that planning models will be used in this connection for better communication.

summary Knowledge-representation languages have been classified traditionally as declarative or procedural, depending on whether their basic features come from mathematical logic or data structures on one hand, or from programming languages on the other hand. Procedural representation languages are particularly well suited for heuristic knowledge, and their use can lead to efficient searching on the part of an expert system. Many attempts have been made to integrate features of declarative and procedural representation languages. PSN is one attempt that focuses on the integration of semantic network and procedural notions
