title	Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source	Delft University of Technology
summary	The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

title	Reflexiones sobre el Diseño Arquitectónico en la Era Digital (Reflections on Architectural Design in the Digital Era)
source	SIGraDi’2000 - Construindo (n)o espacio digital (constructing the digital Space) [4th SIGRADI Conference Proceedings / ISBN 85-88027-02-X] Rio de Janeiro (Brazil) 25-28 september 2000, pp. 69-71
summary	The ubiquity of the digital computer is revolutionizing our understanding of architecture, a paradigm shift comparable to the Renaissance real perspective, the Industrial Revolution of the XIX century, and the technological and scientific discoveries of the early part of the XX century. The creation of virtual worlds, with their own laws and logics, is one of the most important contributions of the digital era. The paradigms of modern architecture are being replaced by other models. The advent of the digital age erased the boundary between “original” and “copy”. Working with design fundamentals and not merely with its graphical manifestations will produce a revolution in architectural design, similar to the genetic revolution of decoding the human genome. Centralized, “star-topology” design locations, are being replaced by distributed, “circle-topology” design teams. The direct influence of digital technologies on the analysis, creation, and realization of architecture also must produce similar revolutions in the teaching of architecture.

title	Design Algorithms after Le Corbusier
source	ACADIA Quarterly, vol. 19, no. 4, pp. 17-24
doi	https://doi.org/10.52842/conf.acadia.2000.017
summary	Some views of design are the act as puzzle making, problem solving, evolutionary, and decision-making. All these focus on form generation as constructive, therefore characterizing design as a path-planning problem through a space of possibilities. Design problems consist sets of information divided into initial, intermediate, and goal states. Design in its simplest state consist of a set of operators, sequences (or paths) between initial and goals states. In this paper, I present design algorithms for Le Corbusier because of his distinct compositional techniques particularly for his “White Villas” in which some elements have been identified to recursively occur.

title	The Intelligent Sketch: Developing a Conceptual Model for a Digital Design Assistant
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 137-145
doi	https://doi.org/10.52842/conf.acadia.2000.137
summary	The computer is a relatively new tool in the practice of Architecture. Since its introduction, there has been a desire amongst designers to use this new tool quite early in the design process. However, contrary to this desire, most Architects today use pen and paper in the very early stages of design to sketch. Architects solve problems by thinking visually. One of the most important tools that the Architect has at his disposal in the design process is the hand sketch. This iterative way of testing ideas and informing the design process with images fundamentally directs and aids the architect’s decision making. It has been said (Schön and Wiggins 1992) that sketching is about the reflective conversation designers have with images and ideas conveyed by the act of drawing. It is highly dependent on feedback. This “conversation” is an area worthy of investigation. Understanding this “conversation” is significant to understanding how we might apply the computer to enhance the designer’s ability to capture, manipulate and reflect on ideas during conceptual design. This paper discusses sketching and its relation to design thinking. It explores the conversations that designers engage in with the media they use. This is done through the explanation of a protocol analysis method. Protocol analysis used in the field of psychology, has been used extensively by Eastman et al (starting in the early 70s) as a method to elicit information about design thinking. In the pilot experiment described in this paper, two persons are used. One plays the role of the “hand” while the other is the “mind”- the two elements that are involved in the design “conversation”. This variation on classical protocol analysis sets out to discover how “intelligent” the hand should be to enhance design by reflection. The paper describes the procedures entailed in the pilot experiment and the resulting data. The paper then concludes by discussing future intentions for research and the far reaching possibilities for use of the computer in architectural studio teaching (as teaching aids) as well as a digital design assistant in conceptual design.

title	Building product information search by images
source	Timmermans, Harry (Ed.), Fifth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Nijkerk, the Netherlands)
summary	Building product information is required during the architectural design and technical design. The common access to the technical information system is the multi-criteria search mode. This search mode is adapted to the situation where an architect has a precise demand of information. But most of the time, the architect looks for ideas and wants to obtain many illustrations of product uses. Therefore, the system has to propose another search mode adapted to the situation where the demand is still fuzzy. Considering that the architect has the capacity to think with image and that an image can generate easily ideas, then a search by images seems to be suitable to the situation where an architect looks for ideas. The web is an inexhaustible resource of images we can exploit to provision an image database on a specific area. The system we propose allows making building product information search with images extracted from the web. This article presents the method used to extract images from web sites of French building product companies and how these images are used in an interactive and progressive image retrieval process.

title	On the Translation of Design Data into Design Form in Evolutionary Design
source	International Conference on Generative Art
summary	The marriage of advanced computational methods and new manufacturing technologies give rise to new paradigms in design process and execution. Specifically, the research concerns itself with the application of Generative and Evolutionary computation to the production of mass-customized products and building components. The work is based on the premise that CAD-CAM should evolve into a dynamic, intelligent, multi-user environment that encourages creativity and actively supports the evolution of individual, mass-customized designs that exhibit common features. The concept of Parametric Design is well established, and chiefly concerns itself with generating design sets that exists within the boundaries of pre-set parametric values. Evolutionary Design extends the notion of parametric control by using rule-based generative algorithms to evolve common families of individual design solutions. These can be optimized according to particular criteria, or can form a wide variety of hierarchically related design solutions, while supporting design intuition. The integration of Evolutionary Design with CAD-CAM, in particular the areas of flexible manufacturing and mass-customization, creates a unique scenario which exploits the full power of both approaches to create a new design-process paradigm that can generate limitless possibilities in a non-deterministic manner within a variable search-space of possible solutions.This paper concerns itself with the technical and philosophical aspects of the codification, generation and translation of data within the evolutionary-parametric design process. The efficiency and relevance of different methods for treating design data form the most fundamental aspect within the realm of CAD/CAM and are crucial to the successful implementation of Evolutionary Design mechanisms. This begins at the level of seeding and progresses through the entire evolutionary sequence, including the codification for evaluation criteria. Furthermore, the integration of digital design mechanisms with CAM and CNC technologies requires further translation of data into manufacturable formats. This paper examines different methods available to system designers and discussed their effect on new paradigms of digital design methods.

title	A Virtual Reality Tool to Implement City Building Codes on Capitol View Preservation
source	Eternity, Infinity and Virtuality in Architecture [Proceedings of the 22nd Annual Conference of the Association for Computer-Aided Design in Architecture / 1-880250-09-8] Washington D.C. 19-22 October 2000, pp. 203-209
doi	https://doi.org/10.52842/conf.acadia.2000.203
summary	In urban planning, the urban environment is a very complicated system with many layers of building codes cross-referenced and interacting together to guide urban growth. Especially, if a new urban design is located in a historical area, additional restrictions will be imposed upon regular zoning regulations to maintain the area’s historical characteristics. Often, urban regulations read as text are difficult to understand. A tool that generates adequate urban information and a quick visualization of the design will ease decision-making and enhance urban design processes. The goal of this research project is to develop a virtual reality (VR) tool with high resolution, speedy computation, and a userfriendly environment. This project initiates an interactive visualization tool to enforce city-planning regulations on viewing access to the state capitol building in Des Moines, Iowa. The capitol building houses the Iowa Legislature and is a symbol of state power. Maintaining the view from surrounding areas will preserve the building’s monumental and symbolic meaning. To accomplish this, the City Community Development Department and the Capitol Planning Committee developed a Capitol View Corridor Project, which sets up seven visual corridors to prevent the view toward the capitol from being blocked by any future designs. Because city regulations are not easy for the public and designers to interpret and comprehend, this project intends to develop a VR tool to create a transparent environment for visualizing the city ordinances.

title	Immersive VR for Scientific Visualization: A Progress Report
source	IEEE Computer Graphics and Applications, Vol. 19, no. 6, Nov/Dec, 26-52
summary	Immersive virtual reality (IVR) has the potential to be a powerful tool for the visualization of burgeoning scientific data sets and models. In this article we sketch a research agenda for the hardware and software technology underlying IVR for scientific visualization. In contrast to Brooks' excellent survey last year, which reported on the state of IVR and provided concrete examples of its production use, this article is somewhat speculative. We don't present solutions but rather a progress report, a hope, and a call to action, to help scientists cope with a major crisis that threatens to impede their progress.

title	Conceptual design: issues and challenges
source	Computer-Aided Design, Vol. 32 (14) (2000) pp. 849-850
summary	Decisions made during conceptual design have significant influence on the cost, performance, reliability, safety and environmental impact of a product. It has been estimated that design decisions account for more than 75% of final product costs. It is, therefore, vital that designers have access to the right tools to support such design activities. In the early 1980s, researchers began to realize the impact of design decisions on downstream activities. As a result, different methodologies such as design for assembly, design for manufacturing and concurrent engineering, have been proposed. Software tools that implement these methodologies have also been developed. However, most of these tools are only applicable in the detailed design phase. Yet, even the highest standard of detailed design cannot compensate for a poor design concept formulated at the conceptual design phase. In spite of this, few CAD tools have been developed to support conceptual design activities. This is because knowledge of the design requirements and constraints during this early phase of a product's life cycle is usually imprecise and incomplete, making it difficult to utilize computer-based systems or prototypes. However, recent advances in fields such as fuzzy logic, computational geometry, constraints programming and so on have now made it possible for researchers to tackle some of the challenging issues in dealing with conceptual design activities. In this special issue, we have gathered together discussions on various aspects of conceptual design phase: from the capturing of the designer's intent, to modelling design constraints and solving them in an efficient manner, to verifying the correctness of the design.

title	SpaceScope: Developing a Spatial Information Retrieval System - Focused on Apartment Unit Floor Plans -
source	Yonsei University, Dept. of Housing & Interior Design
summary	This research investigates the spatial information retrieval (IR) in architecture focused on constructing efficient metadata that is crucial for data retrieval. Generally speaking, metadata is ‘structured data about data’ to describe resources especially in a digital format. In this research, metadata is a sort of data object to be useful in searching spatial information. Metadata is also used to describe raw spatial data object as not only attribute data but also content structurally and semantic ally. There are two issues that motivate this research; 1) what is the spatial information – that materializes the intangible space as a data object, and 2) how we can search the information efficiently – the content-based information retrieval. Although knowledge of a building’s spatial content is most important in architecture, there has been no logical method to manage it. From the viewpoint of content-based retrieval, the researcher analyzes spatial information of a floor plan, with a focus on the apartment unit floor plan common in Korea. Then the metadata items are extracted in a structured manner. To manage the items efficiently, the researcher develops a data model for spatial information according to the concept of the “Structured Floor Plan”. The main object of content to retrieve is a spatial network that consists of nodes of spaces and their linkages. There are two ways to organize the metadata: the traditional index files and the RDF (Resource Description Framework). While the index files are still efficient with computability, the RDF applies greater options to retrieve, such as fuzzy predicates, semantic predicates, and so on. To exploit the metadata, this research shows several possibilities of query operations that present a set of sample queries about L-DK(Living room – Dining room – Kitchen). Implementation of the prototype system is divided into three parts: 1) a modeling module using Vitruvius; 2) an indexing module using MS SQL Server? 2000 in conjunction XML; and 3) a browsing module using the SpaceScope browser. The future works may consider XML-based databases and a knowledge based query language, such as RQL/XQL, working on such databases. The more specific domain knowledge is involved, the more practical systems would be. Even in architecture, there may be a diverse range of domain knowledge, such as design, building performance, facility management, energy management, post occupied evaluation, historical research, and so on. Also the issue of interface should be investigated in depth, so that it will be adequate to the needs of the architectural field.

title	Information systems for monitoring land use planning in the Finnish Environmental Administration. GISALU (Land Use GIS) and KATSE (the Information System for Monitoring Land Use Planning)
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The primary aim of the monitoring of land use planning is to obtain information about the state and development of land use planning. The new Land Use and Building Act of Finland has obliged the authorities to monitor land use since the beginning of the year 2000. Two information systems help to fulfil this task in the Finnish Environmental Administration. GISALU (Land Use GIS) is a collection of data sets containing geographical data on land use plans, deviation decisions and the cultural environment. KATSE(the Information System for Monitoring Land Use Planning) mainly contains statistical data on the state of planning as a whole and changes in it. GISALU is an important information source for KATSE. Both information systems form part of ALUTJ (the information systems for land use), and they are also subsystems of HERTTA (the Finnish Environmental Information System).

title	Constraint-based support for negotiation in collaborative design
source	Artificial Intelligence in Engineering, Vol: 14, Issue: 3, pp. 261-280.
summary	Solution spaces are proposed, instead of single solutions only, to support collaborative tasks during design and construction. Currently, partners involved in construction projects typically assign single values for sub-sets of variables and then proceed, often after tedious negotiations with other partners, to integrate these partial solutions into more complete project descriptions. We suggest the use of constraint solving to express possibly large families of acceptable solutions in order to improve the negotiation process in two ways. On one hand, con ict detection can be performed in an automated manner. Through the constraints collaborators impose, they de ne large unfeasible areas where no solution to the problem at hand can be expected. An emty intersectidon of the solution spaces can thus point at a con ict of design goals of the di erent collaborators at an early stage of the design process. On the other hand, important decision support during negotiation is provided. When a solution space is found, collaborators know during negotiation that they are negotiating about feasible solutions. Negotiation is no longer a means to nd a solution to the problem but it takes place in order to nd a good or the best solution. Since the consistency of the design remains ensured, collaborators are expected to be less restrictive towards innovative ideas during negotiation. Moreover, constraint techniques using explicit representations of solution spaces can provide tools to visualize trade-o s and illustrate the impact of certain decisions on other parameters. Thus decision-making is improved during the negotiation. New algorithms have been developed at EPFL for solving multi-dimensional nonlinear inequality constraints on continuous variables. Together with intuitive user interfaces such constraint-based support leads to better change management and easier implementation of least commitment decision strategies. It is expected that the results of this research can improve both the e ciency of negotiation processes and the quality of the achieved results.

doi	https://doi.org/10.52842/conf.acadia.2000.213
summary	Issues associated with virtual reconstruction are first dealt within this paper. Visualizing of no longer existent (architecture-) objects and their surroundings practically amounts to a “virtual comeback”. Furthermore, special attention is given to the description of the working procedure for a case study of reconstruction sounding out the potentials of QuickTime VR. The paper ends up with a set of conclusions, taking a close look at the “pros” and “cons” of this type of re-construction. 1 Introduction Irreversible destruction having removed identity-establishing buildings from the urban surface for all times is the principal cause for the attempt of renewed “imaginating.” When dealing with such reconstruction first the problem of reliability concerning the existing basic material has to be tackled. Due to their two-dimensional recording photographs only supply us with restricted information content of the object under consideration. Thus the missing part has to be supplemented or substituted by additional sources. Within the process of assembling and overlaying of differing data sets the way of dealing with such fragmentations becomes of major importance. Priority is given to the choice of information. One of the most elementary items of information regarding perception of three-dimensional objects surely is the effect that color and material furnishes. It seems to suggest itself that black-and-white shots hardly will prove valid in this respect. The three-dimensional object doubtlessly provides us with a by far greater variety of possibilities in the following working process than the “cardboard model with pasted-on facade photography”. Only the completely designed model structure makes for visualizing the plastic representation form of architecture in a sustainable manner. Furthermore, a virtual model can be dismantled into part models without amounting to a destruction process thereof. Apart therefrom the virtual model permits the generation of differing reconstruction variants regarding color and material. Moreover, architecture models of a physical nature are inherently connected to locality as such.

title	Abstracting Craft: The Practised Digital Hand
source	MIT Press, Cambridge Mass.
summary	Can designing for computers be a craft? This is the question this book sets out to answer. At first sight, the situation is unpromising: craft is the work of hands, and "hands are underrated," in modern life; especially as computers are seen as abstract, conceptual, creations of pure mind. Yet since computation has become a medium, rather than just a tool kit, the correspondence between digital work and traditional craft is increasing. Modern software products, though immaterial, are nevertheless the creation of "practised hands" and eyes, as well as minds. Moreover, to craft is to care: humane values can - and should - inform a software designer's work just as a potter's or carpenter's. McCullough gives all those who work with code the chance to proclaim: "I am not a programmer! I am a digital craftsperson!"

title	ArTbitrariness in Music
source	International Conference on Generative Art
summary	Evolution is now considered not only powerful enough to bring about the biological entities as complex as humans and conciousness, but also useful in simulation to create algorithms and structures of higher levels of complexity than could easily be built by design. In the context of artistic domains, the process of human-machine interaction is analyzed as a good framework to explore creativity and to produce results that could not be obtained without this interaction. When evolutionary computation and other computational intelligence methodologies are involved, every attempt to improve aesthetic judgement we denote as ArTbitrariness, and is interpreted as an interactive iterative optimization process. ArTbitrariness is also suggested as an effective way to produce art through an efficient manipulation of information and a proper use of computational creativity to increase the complexity of the results without neglecting the aesthetic aspects [Moroni et al., 2000]. Our emphasis will be in an approach to interactive music composition. The problem of computer generation of musical material has received extensive attention and a subclass of the field of algorithmic composition includes those applications which use the computer as something in between an instrument, in which a user "plays" through the application's interface, and a compositional aid, which a user experiments with in order to generate stimulating and varying musical material. This approach was adopted in Vox Populi, a hybrid made up of an instrument and a compositional environment. Differently from other systems found in genetic algorithms or evolutionary computation, in which people have to listen to and judge the musical items, Vox Populi uses the computer and the mouse as real-time music controllers, acting as a new interactive computer-based musical instrument. The interface is designed to be flexible for the user to modify the music being generated. It explores evolutionary computation in the context of algorithmic composition and provides a graphical interface that allows to modify the tonal center and the voice range, changing the evolution of the music by using the mouse[Moroni et al., 1999]. A piece of music consists of several sets of musical material manipulated and exposed to the listener, for example pitches, harmonies, rhythms, timbres, etc. They are composed of a finite number of elements and basically, the aim of a composer is to organize those elements in an esthetic way. Modeling a piece as a dynamic system implies a view in which the composer draws trajectories or orbits using the elements of each set [Manzolli, 1991]. Nonlinear iterative mappings are associated with interface controls. In the next page two examples of nonlinear iterative mappings with their resulting musical pieces are shown.The mappings may give rise to attractors, defined as geometric figures that represent the set of stationary states of a non-linear dynamic system, or simply trajectories to which the system is attracted. The relevance of this approach goes beyond music applications per se. Computer music systems that are built on the basis of a solid theory can be coherently embedded into multimedia environments. The richness and specialty of the music domain are likely to initiate new thinking and ideas, which will have an impact on areas such as knowledge representation and planning, and on the design of visual formalisms and human-computer interfaces in general. Above and bellow, Vox Populi interface is depicted, showing two nonlinear iterative mappings with their resulting musical pieces. References [Manzolli, 1991] J. Manzolli.

summary	Since 1996, Kumamoto University has repeated several experiments to apply web-based collaborative design techniques to a junior design studio to stimulate students’ interaction in the class and to enhance their design abilities. As it became evident after a two-year experiment that writing web pages and uploading them to a web server was a barrier of communication for students, the authors developed a web-based groupware called GWNotebook, and started using it in 1998. In the fall semester of 2000, the authors tested the groupware in a revised version, and a new program of studio instructions that assumed the use of the groupware. This paper, referring students’ answers to two sets of questionnaire respectively carried out in 1997 and 2000, discusses the effectiveness of groupware and the instruction program.

summary	This paper sets out to define aspects of the architectural design process, using historical precedent and architectural theory, and tests the relationship of those aspects to the application of computers in architectural design, particularly in an educational context. The design process sub-sets are defined as: Forming, Planning, Imaging and Connecting. Historical precedents are uncovered in Classical, Modern, Postmodern and Contemporary architecture. The defined categories of the design process are related to current usages of computers in architectural education towards elucidating the strengths and weaknesses of digital media in those areas. Indications of their concurrent usage in digital design will be demonstrated in analysis of design studio programs presented at recent ACADIA conferences. An example of a current design studio programme set at the School of Architecture University of Natal, South Africa in which the above described categories give an underlying structure to the introduction of 3D digital modelling to undergraduates through design process. The definition of this set of design activities may offer a useful method for other educators in assessing existing and future design programs where digital tools are used.

title	Algorithms of the Mind. The generative art of drawing
source	International Conference on Generative Art
summary	Throughout the disciplines of art and design, interest in the possibilities of algorithmic methods for generating two- and three-dimensional visual forms grows apace. Evidence supporting this observation may be found in the increasingly diverse range of contributions to the Generative Art conferences. Two research scenarios may be identified: 1 in which the generative process itself is the object of research, 2 in which the forms generated are the objects of research. The question of what criteria may be appropriate to the evaluation of such research is addressed in this paper. Lincoln and Guba's term "criteria of authenticity" is elaborated in a case study based on the author's research into teaching drawing to fine art undergraduates. Although the drawings produced are not computer-generated, it is argued that the concept of 'algorithm' as a set of rules for the generating of visual representations may be usefully applied to the mental ontological constructions, or 'mind-set', of the student. Such mind-sets affect the ways that drawings are constructed. It is suggested that a teaching method which enables students to recognise their mental algorithms as cultural constructions, may also empower them to reconstruct those algorithms in order to generate visual representations previously unimagined.

summary	In the first part of the paper theoretical aspects are briefly discussed, followed by an equally brief description of special procedures. In the second part, working in a concrete problem, a case study about public libraries interior design is exposed to illustrate positioning procedures. Computer graphics techniques are used in the generation of a large range of possible locations of typical library furniture. The results are governed by sets of rules, which are introduced following functional and dimensional needs. The case of public libraries is intended to be just one example of the general system directed to locate objects in the space. The discussion of different alternatives is accompanied by drawings showing geometrical aspects in correspondence with the specifical case of the small public libraries reading rooms.
