title "To See Ideas" or The Visualizing of Programmatic Data Reading Examples in Architecture and Town Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Whether images are still in the mind, metaphors, sketches or icons, they play a crucial role. They have always been the heuristic pivot around which the process of artefact design organizes itself, particularly in architecture and town-planning. "To see ideas" through computer ideograms is to experiment an interesting and new direction for "pictural approach" supported design. Cognitive psychology emphasizes the important part played by mental images in reasoning, imagination in the working of human intelligence and the construction of mental images as cognitive factors underlying reasoning. It also points out how close computerized objects and mental schemata are. "To reason over a situation is first to remember or build some mental models of this situation; second to make those models work or simulate them in order to observe what would happen in different circumstances and then verify whether they fit the experiment data; third to select the best model, a tool meant to sustain and amplify the elaboration of mental models, which is a spontaneous activity". We introduce our exploration of the direct transmission of mental models through computer ideograms. We study the "operative" and the "expressive" aspects, and this allows us to analyze how some aspects in a field of knowledge are represented by ideograms, schemata, icons, etc. Aid to imagination, reasoning and communication by means of a graphic language must be limited to some figurative relevant aspects of the domain considered; it should not aim at a realistic simulation. Therefore, the important role played by icons and the spatial schematic representation of knowledge is emphasized. Our hypothesis is that an architectural concept does not result from an inductive process, but rather is built to solve problems through the direct representation of ideas with ideograms. An experiment was conducted with a graphic language, a dynamic scenography and actor-objects. The language allows one to build and visualize models from the various domains of knowledge of the object. The dynamic scenography can explore and simulate kinetically those models by means of staging various narrations and visual scenarios. The actor-objects play various and complementary parts in order to make the image explicit and link it with the concept. We distinguish between two parallel levels of reality in computer ideographics: one concerns the model, it represents the visualization of a graphic model at a particular moment and according to a particular representation, the other concerns the ideogram.

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.

title A digital Procedure of Building Construction: A practical project
source AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary In earlier times in which computers have not yet been developed well, there has been some researches regarding representation using conventional media (Gombrich, 1960; Arnheim, 1970). For ancient architects, the design process was described abstractly by text (Hewitt, 1985; Cable, 1983); the process evolved from unselfconscious to conscious ways (Alexander, 1964). Till the appearance of 2D drawings, these drawings could only express abstract visual thinking and visually conceptualized vocabulary (Goldschmidt, 1999). Then with the massive use of physical models in the Renaissance, the form and space of architecture was given better precision (Millon, 1994). Researches continued their attempts to identify the nature of different design tools (Eastman and Fereshe, 1994). Simon (1981) figured out that human increasingly relies on other specialists, computational agents, and materials referred to augment their cognitive abilities. This discourse was verified by recent research on conception of design and the expression using digital technologies (McCullough, 1996; Perez-Gomez and Pelletier, 1997). While other design tools did not change as much as representation (Panofsky, 1991; Koch, 1997), the involvement of computers in conventional architecture design arouses a new design thinking of digital architecture (Liu, 1996; Krawczyk, 1997; Murray, 1997; Wertheim, 1999). The notion of the link between ideas and media is emphasized throughout various fields, such as architectural education (Radford, 2000), Internet, and restoration of historical architecture (Potier et al., 2000). Information technology is also an important tool for civil engineering projects (Choi and Ibbs, 1989). Compared with conventional design media, computers avoid some errors in the process (Zaera, 1997). However, most of the application of computers to construction is restricted to simulations in building process (Halpin, 1990). It is worth studying how to employ computer technology meaningfully to bring significant changes to concept stage during the process of building construction (Madazo, 2000; Dave, 2000) and communication (Haymaker, 2000).In architectural design, concept design was achieved through drawings and models (Mitchell, 1997), while the working drawings and even shop drawings were brewed and communicated through drawings only. However, the most effective method of shaping building elements is to build models by computer (Madrazo, 1999). With the trend of 3D visualization (Johnson and Clayton, 1998) and the difference of designing between the physical environment and virtual environment (Maher et al. 2000), we intend to study the possibilities of using digital models, in addition to drawings, as a critical media in the conceptual stage of building construction process in the near future (just as the critical role that physical models played in early design process in the Renaissance). This research is combined with two practical building projects, following the progress of construction by using digital models and animations to simulate the structural layouts of the projects. We also tried to solve the complicated and even conflicting problems in the detail and piping design process through an easily accessible and precise interface. An attempt was made to delineate the hierarchy of the elements in a single structural and constructional system, and the corresponding relations among the systems. Since building construction is often complicated and even conflicting, precision needed to complete the projects can not be based merely on 2D drawings with some imagination. The purpose of this paper is to describe all the related elements according to precision and correctness, to discuss every possibility of different thinking in design of electric-mechanical engineering, to receive feedback from the construction projects in the real world, and to compare the digital models with conventional drawings.Through the application of this research, the subtle relations between the conventional drawings and digital models can be used in the area of building construction. Moreover, a theoretical model and standard process is proposed by using conventional drawings, digital models and physical buildings. By introducing the intervention of digital media in design process of working drawings and shop drawings, there is an opportune chance to use the digital media as a prominent design tool. This study extends the use of digital model and animation from design process to construction process. However, the entire construction process involves various details and exceptions, which are not discussed in this paper. These limitations should be explored in future studies.

source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 133-139
summary Bases de datos, Sistemas y Redes 134The purpose of this report is to present the achievements obtained in the use of the technologies of information andcommunication in the architecture, by means of the construction of a database to register the information on the modernarchitecture of the city of Maracaibo from 1920 until 1990, in reference to the constructions located in 5 of Julio, Sectorand to the most outstanding planners for its work, by means of the representation of the same ones in digital format.The objective of this investigation it was to elaborate a database for the registration of the information on the modernarchitecture in the period 1920-1990 of Maracaibo, by means of the design of an automated tool to organize the it datesrelated with the buildings, parcels and planners of the city. The investigation was carried out considering three methodologicalmoments: a) Gathering and classification of the information of the buildings and planners of the modern architectureto elaborate the databases, b) Design of the databases for the organization of the information and c) Design ofthe consultations, information, reports and the beginning menu. For the prosecution of the data files were generated inprograms attended by such computer as: AutoCAD R14 and 2000, Microsoft Word, Microsoft PowerPoint and MicrosoftAccess 2000, CorelDRAW V9.0 and Corel PHOTOPAINT V9.0.The investigation is related with the work developed in the class of Graphic Calculation II, belonging to the Departmentof Communication of the School of Architecture of the Faculty of Architecture and Design of The University of the Zulia(FADLUZ), carried out from the year 1999, using part of the obtained information of the works of the students generatedby means of the CAD systems for the representation in three dimensions of constructions with historical relevance in themodern architecture of Maracaibo, which are classified in the work of The Other City, generating different types ofisometric views, perspectives, representations photorealistics, plants and facades, among others.In what concerns to the thematic of this investigation, previous antecedents are ignored in our environment, and beingthe first time that incorporates the digital graph applied to the work carried out by the architects of “The Other City, thegenesis of the oil city of Maracaibo” carried out in the year 1994; of there the value of this research the field of thearchitecture and computer science. To point out that databases exist in the architecture field fits and of the design, alsoweb sites with information has more than enough architects and architecture works (Montagu, 1999).In The University of the Zulia, specifically in the Faculty of Architecture and Design, they have been carried out twoworks related with the thematic one of database, specifically in the years 1995 and 1996, in the first one a system wasdesigned to visualize, to classify and to analyze from the architectural point of view some historical buildings of Maracaiboand in the second an automated system of documental information was generated on the goods properties built insidethe urban area of Maracaibo. In the world environment it stands out the first database developed in Argentina, it is the database of the Modern andContemporary Architecture “Datarq 2000” elaborated by the Prof. Arturo Montagú of the University of Buenos Aires. The general objective of this work it was the use of new technologies for the prosecution in Architecture and Design (MONTAGU, Ob.cit). In the database, he intends to incorporate a complementary methodology and alternative of use of the informationthat habitually is used in the teaching of the architecture. When concluding this investigation, it was achieved: 1) analysis of projects of modern architecture, of which some form part of the historical patrimony of Maracaibo; 2) organized registrations of type text: historical, formal, space and technical data, and graph: you plant, facades, perspectives, pictures, among other, of the Moments of the Architecture of the Modernity in the city, general data and more excellent characteristics of the constructions, and general data of the Planners with their more important works, besides information on the parcels where the constructions are located, 3)construction in digital format and development of representations photorealistics of architecture projects already built. It is excellent to highlight the importance in the use of the Technologies of Information and Communication in this investigation, since it will allow to incorporate to the means digital part of the information of the modern architecturalconstructions that characterized the city of Maracaibo at the end of the XX century, and that in the last decades they have suffered changes, some of them have disappeared, destroying leaves of the modern historical patrimony of the city; therefore, the necessity arises of to register and to systematize in digital format the graphic information of those constructions. Also, to demonstrate the importance of the use of the computer and of the computer science in the representation and compression of the buildings of the modern architecture, to inclination texts, images, mapping, models in 3D and information organized in databases, and the relevance of the work from the pedagogic point of view,since it will be able to be used in the dictation of computer science classes and history in the teaching of the University studies of third level, allowing the learning with the use in new ways of transmission of the knowledge starting from the visual information on the part of the students in the elaboration of models in three dimensions or electronic scalemodels, also of the modern architecture and in a future to serve as support material for virtual recoveries of some buildings that at the present time they don’t exist or they are almost destroyed. In synthesis, the investigation will allow to know and to register the architecture of Maracaibo in this last decade, which arises under the parameters of the modernity and that through its organization and visualization in digital format, it will allow to the students, professors and interested in knowing it in a quicker and more efficient way, constituting a contribution to theteaching in the history area and calculation. Also, it can be of a lot of utility for the development of future investigation projects related with the thematic one and restoration of buildings of the modernity in Maracaibo.

title On visual design thinking: the via kids of architecture
source Design Studies 15 (2), pp. 158-174
summary Designers invariably use imagery to generate new form combinations which they represent through sketching. But they also do the reverse: they sketch to generate images of forms in their minds. Common belief regards such activity as non-rational. In contrast, we assert that interactive imagery through sketching is a rational mode of reasoning, characterized by systematic exchanges between conceptual and figural arguments. Cognitive science, strongly dominated by a linguistic paradigm, has yet to recognize the paramount role of visual reasoning in many instances of problem solving; and in design tool-making, computational and otherwise, we must learn to optimize rather than bypass intuitive visuality.

summary This book captures and binds disparate streams of information in a single volume and attempts to reconnect us to the experience of architecture through holding a book in our hands. Just as architecture uses the connections among the dissimilar as the sites for design intervention and invention, the content of this book attempts to connect the objective processes that are characteristic of computers with the subjective processes that are characteristic of creativity. The chosen format juxtaposes technical work in the first half with pedagogical explorations in the second half. By recognizing their differences and separating them from each other, the process of reconnecting can occur. Within both the technical and pedagogical sections, a continuous stream of information connects the papers across the bottom of the page. Against the technical papers, we have placed the keynote paper by Professor Paul Laseau. Against the pedagogical papers, we have placed a drawing done by Trent Tesch that is a visual interpretation of cyberspace based on the novel, Neuromancer, by William Gibson. While turning these pages, consider the accidents that take place through the juxtaposition of streams of thought sharing a single page.

title Applying Visual Design: Trade Secrets for Elegant Interfaces TUTORIALS
source Proceedings of ACM CHI'94 Conference on Human Factors in Computing Systems 1994 v.2 pp. 353-354
summary This tutorial describes a number of fundamental techniques applied routinely in communication-oriented visual design. The orientation, process, training, and culture of the visual design disciplines (graphic design, industrial design, interior design, architecture) are essential components of effective interface design. Unfortunately, few software developers or human factors engineers receive any training in these disciplines. This tutorial describes important design rules and techniques internalized by every visual designer through coursework and studio experience. While mastery will indeed require extended practice, the techniques we describe are not difficult to understand and can be immediately applied to real-world problems. We draw our background, training, and influence from the rational, functional, information oriented perspective of the Modernist design ethic. Because all graphical user interfaces are communication systems, we believe their design should reflect these same values. Our tutorial is organized not along the traditional subdisciplines of color, typography, or ideation, but along the problems of graphical interface design as experienced in commercial software development. We describe basic design principles (the what and why), common errors, and practical techniques (the how) for each of the six major areas outlined below. (1) Elegance and Simplicity (2) Scale, Contrast and Proportion (3) Organization and Visual Structure (4) Module and Programme (5) Image and Representation (6) So What About Style?

title The Reflective Eye: Visual Reasoning in the Sketch
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Despite recent advances in our understanding of design thinking, we still lack a comprehensive theoretical approach to cognitive processes in design and particularly to visual reasoning. Of scientific interest in its own right, understanding non-verbal reasoning is also relevant to a wide range of subjects in the area of visual data resources for designers. This paper presents research into visual reasoning through the study of cognitive acts and processes associated with design drawing. Employing case studies in the design sketch, a vocabulary is defined for describing phenomena of visual reasoning in design as they are revealed in the sketch. Classes of reasoning processes are proposed as strings of graphic acts of state transformation. A theoretical schema is developed which relates the individual act of visual reasoning manifested in the sketch, of sketch sequences, with larger global cognitive phenomena such as analogical or associative reasoning in design. Based upon this schema, a symbol system for these acts and processes is proposed as a coding technique in the observation, analysis and recording of non-verbal processes in design.

title Using Post-Occupancy Evaluation To AID Reflection in ConceptualDesign: Creating a Case-Based Design Aid For Architecture
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The design of large complex "real-world" objects such as buildings requires that the intentions of many potentially competing stakeholders be understood and reconciled. The process of conceptual design itself can be understood as a set of discourses among design team participants and between the designer and the design that gradually reveal these intentions and their relationships to design moves. Our goal is to aid this discourse by creating a Case-based Design Aid (CBDA) that provides design team participants access to specific evaluated cases of experience with previous buildings. This represents a merger of two sets of theories and methodologies: case-based reasoning (CBR) in artificial intelligence; and, post-occupancy evaluation (POE) in architectural research. In developing our CBDA, we have focused on several problems in architectural design: understanding the interactions between intentions, and making links between various modes of understanding and communication, and particularly between verbal description and visual representation. This has led to a particular way of parsing experience, and to several modes of entering and browsing the system. For instance, each case is accessible as a specific building, such as the Santa Clara County Hall of Justice, that can be explored much as an architect might browse a magazine article about the building, looking at a brief text description of the building, photos, and plans. However, each plan is annotated with "problematic situations" that are actually hypertext links into the discursive part of the program. By clicking on the button, the users reaches a "story" screen that lists the intentions of various stakeholders relevant to the problematic situation, a fuller text description of the general problematic situation with a diagram, text and diagram for a specific problematic situation as it operates in a specific building, several general design responses showing how one might respond to the problematic situations, and specific design responses from specific buildings. In addition, the user can browse the system by listing his or her interests and moving directly to stories about a given space type such as "courtroom" or issue such as "way finding." In addition, the designer can access brief synopses of key issues in a building type, for a space type, or for an issue. We are currently implementing the system on the Macintosh using Common Lisp and are focusing on libraries and courthouses as initial building types. Initial feedback from designers has been encouraging. We believe that this approach provides a useful alternative to design guidelines, that often tend to be too prescriptive, and the entirely inductive approach of many designers that may miss critical intentions.

title Fractal Cities - A Geometry of Form and Function
source Academic Press, London
summary Fractal Cities is a pioneering study of the development and use of fractal geometry for understanding and planning the physical form of cities, showing how this geometry enables cities to be simulated through computer graphics. It shows how cities evolve and grow in ways that at first sight appear irregular, but which, when understood in terms of fractals, illustrate an underlying order that reveals their complexity and diversity. The book contains sixteen pages of stunning computer graphics and explanations of how to construct them, as well as new insights into the complexity of social systems. The authors provide a gentle and intelligible introduction to fractal geometry as well as an exciting visual understanding of the form of cities, thus providing one of the best introductions to fractal geometry available for non-mathematicians and social scientists. Fractal Cities can be used as a text for courses on geographic information systems, urban geography, regional science and fractal geometry. Planners and architects will also find that there are many aspects of fractal geometry in this book relevant to their own interests. Furthermore, those involved in fractals and chaos, computer graphics, and systems theory will find important methods and examples that are germane to their work.

title Osmose: Towards Broadening the Aesthetics of Virtual Reality
source ACM Computer Graphics: Virtual Reality Volume 30, Number 4
summary Osmose is an immersive virtual environment, produced by Softimage in 1994/95. One of the primary goals of Osmose was to push the expressive capabilities of existing 3D tools, to demonstrate that an alternative aesthetic and interactive sensibility is possible for real-time, interactive, 3D computer graphics. Osmose was created under the direction of Char Davies, the Director of Visual Research at Softimage. A former painter, as well as a creator of 3D computer graphic stills, Davies has a particular artistic vision which has driven the project. Davies has been striving for years to represent space as a luminous enveloping medium. This has led her from painting to 3D computer graphics, and finally into creating immersive virtual spaces. One of Davies' intentions for Osmose was to create a space that is "psychically innovating," one in which, to quote Bachelard, participants do not change "place," but change their own nature. Osmose was therefore designed to explore the potential of immersive virtual space to allow participants to shed their habitual ways of looking at (and behaving in) the world. By doing this, we hoped they would then emerge from the virtual world to experience the real world in a fresh way, reawakening a fundamental sense of their own "being-in-the-world." We hoped that this could be accomplished through the visual, aural and interactive aesthetic of the work.

summary Augmented Reality (AR) technologies are often perceived as the most impactful method to enhance the communication between the designer and the client during the iterative design process. However, the significance of designing the User Interface (UI) and the User Experience (UX) are often underestimated. To intercede, this research aims to employ new and existing techniques to develop UI's, and comparatively assess "the accuracy and completeness with which specified users can achieve specified goals in particular environments" (Stone, 2005) - a notion this research delineates as 'effectiveness'. Prompted by the work of key scholars, the developed UI's were assessed through the lens of existing UI evaluation techniques, including: Usability Heuristics (Nielsen, 1994) and Visual and Cognitive Heuristics (Zuk and Carpendale, 2006). In partnership with PTW Architects, characteristics such as the rapidity and complexity of interactions, in conjunction with the interface's simplicity and intuitiveness, were extracted from 15 trials underwent by architectural practitioners. The outcomes of this research highlights strategies for the effective development of user interface design for mobile augmented reality applications.

summary At a time when requirements on the quality of the built environment are increasingly becoming explicit and specific, computer technology promises the ability to analyse and evaluate buildings during the design process. The computer can extract the necessary information from conventional geometric representations, generate comprehensive descriptions of the aspects to be analysed and use these to arrive at precise and accurate results that can be represented visually. Visual representations facilitate comprehension of the analyses and of their results because of their agreement with our predominantly visual perception of the built environment. The consequent close correspondences between geometric design representations and the visual representation of analyses and evaluations allow direct correlation of the results with the design as a whole. Such correlation is instrumental for imposing explicit and justifiable constraints on the further development of a design. One good example of visual analyses is daylighting. In many drafting and modelling programs a viewing point can be set on the basis the sun’s height and azimuth. The projection returned reveals the surfaces that are directly lit by the sun. In other programs the sun’s height and azimuth can be used to position a light source with parallel rays. This source gives rise to shading and shadows that correspond to the ones produced by the sun. In addition, several programs can calculate the position of the sun and hence the viewing point or the light source on the basis of the date, the time and the geographic coordinates of the place. The availability of computer-aided daylighting analysis has obvious advantages for practice. Efficiency and reliability of the analysis increase, while flexibility is superior to analog simulations. Unfortunately automation of daylighting analysis may also impede understanding of underlying principles, that is, of the issues at the focus of architectural education. Explaining how the analysis is performed and why becomes thus a necessity for computer-aided design education. Exercises that aim at more than just learning and using a computer program can enrich the student’s understanding of the analysis and its results. The efficiency and flexibility of the computer facilitate the study of aspects such as the comparison of local apparent time, local mean time, standard time and daylight saving time and their significance for daylighting, solar heating and cooling patterns and possibilities. Sundials with their explicit correspondence to solar movement can be instrumental in this respect. The efficiency and flexibility of the computer also support the investigation of the techniques by which the daylighting analysis is performed and explain the relationships between projective theory, sciagraphy and computer graphics. A better understanding of the principles and techniques for daylighting analysis has a generally positive influence on the students’ learning of the daylighting analysis software and more significantly on their correlation of daylighting constraints with their designs. This leads in turn to increased flexibility and adaptability of the designs with respect to daylighting and to a conscious and meaningful exploration of variations and alternative solutions.

title Graphic Data Comprehension In Design Thinking
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary There exist several kinds of data qualities when we see a graphic. In such a procedure, we rarely describe all the qualities by language. This is an interesting phenomenon. We are doing something that we understand but we cannot tell when we are thinking or drawing a graphic. A problem like this touches the central point related to the understanding of drawing in design. It is the purpose of this study. A series of experiments is conducted to compare two sets of data: design by drawing and design without drawing. The major result of this experiment is that the type without drawing contains less design contents and is easy to reassemble. The drawing type contains much richer design contents which easily disappeared when reassembled through the descriptions. We believe there exist two major characters of visual data: nameable and unnameable. Nameable data may be designed and communicated without drawing. For the unnameable one, we may proceed when its qualities show out. According to this study, we conclude that the mental representation of visual data is basically prepositional rather than picture-like. But, in design procedures, the picture-like one may appear when the figure comes out of the mental world, with lots of unnameable qualities.

title Implementing an Integrated Environment for Urban Simulation CAD, Visualization and GIS
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Using technology which has been adapted from military flight simulation hardware and software, researchers at UCLA's Graduate School of Architecture and Urban Planning are currently developing an integrated computing environment for Urban Simulation which includes a high-level visual simulation package, an industry standard CAD system, and a traditional two dimensional geographic information system and data bases. The focal point of the integrated system is a visual simulation engine which has been developed using Silicon Graphics' IRIS Performer application development environment. With this system, aerial photographs can be combined with street level video to efficiently create a realistic (down to plants, street signs and the graffiti on the walls) model of an urban neighbourhood which can then be used for interactive fly and walk-through demonstrations. Links have been established between this visual simulation system and AutoCAD to allow models (at varying levels of detail) to be generated using the CAD system and translated into the form required for the visualization system. Links between the GIS system (in this case ARC/INFO and ARCVIEW) and the visual simulation system provide the capability for dynamic query and display of information from the GIS data base in a real-time 3-dimensional format. Links between the CAD and GIS systems allow common base maps to be used for the GIS and modelling systems as well as automatic generation of 3-d form. While an earlier paper by the authors discussed proposed strategies for such an Urban Simulation System, this paper focuses on the results of actual implementation of these strategies, as well as the use of the system for modelling, exploration and display of alternative physical environments.

summary The most valuable resource in education is student time and the greatest asset is the ingenuity of student minds. CAD technology now offers enormous potential to education, but limitations in time and funding, prevent its use to the extent possible within practice. Therefore, after dealing with 'awareness', 'attitude' and 'limited applications', our most important role in education is to encourage innovation. The third year of the honours option course at De Montfort University takes this as its theme and challenges students to explore and exploit innovative applications. One particular area of development has been exploring the dynamic aspects of architectural design which go much further than the well-established 'fly-through' sequences. A great deal of architectural design and design development depends upon dynamic issues which range from movement joints to construction sequence. A visual understanding of these dynamic issues drawn from appropriate computer animations can now be an effective factor in design.

title A Perceptually- Supported Sketch Editor
source Proc. UIST 94, Marina del Rey, CA 175-184
summary The human visual system makes a great deal more of images than the elemental marks on a surface. In the course of viewing, creating, or editing a picture, we actively construct a host of visual structures and relationships as components of sensible interpretations. This paper shows how some of these computational processes can be incorporated into peneptuallysupported image editing tools, enabling machines to better engage users at the level of their own percepts. We focus on the domain of freehand sketch editors, such as an electronic whiteboard application for a pen-based computer. By using computer vision techniques to perform covert recognition of visual structure as it emerges during the course of a drawingkditing session, a perceptually supported image editor gives users access to visual objects as they are perceived by the human visual system. We present a flexible image interpretation architecture based on token grouping in a multiscale blackboard data structure. This organization supports multiple perceptual interpretations of line drawing data, domain-specific knowledge bases for interpretable visual structures, and gesture-based selection of visual objects. A system implementing these ideas, called Per-Sketch, begins to explore a new space of WYPIWYG (What Your Perceive Is What You Get) image editing tools.

title Interaction with Architectural Cases in a Virtual Design Environment
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary The prime business of architecture is change through design. While most architects will welcome any tool which supports this activity with minimal effort, they will not embrace a tool which either seems to automate design or requires major efforts to understand and use. Conventional databases - be it in the form of books or computer applications - are normally in a serving function to support the activity of design and to provide reference. Visual databases have a long history in architecture in the form of drawings, photographs and, more recently, computer-captu-red or computer-generated images. Whereas the first computer-based image libraries closely followed the existing paradigm of existing paper-based libraries, new developments both in software and in computing media offer different opportunities. Knowledge-based and case-based descriptions of architectural features increasingly replace the traditional, passive representations. While in the past these images were subject to more or less random interpretations, the new computer-based images are only one representation of a model which includes many other aspects. The visual aspects of a building are thus no longer restricted to the finished drawing, but new representations of the abstractions of a building become possible. True and direct interaction with visually presented objects thus becomes a reality. The paper presents a prototype of a visual database in a virtual design environment in its critical aspects: (i) the architectural content and representation of such a database and the criteria for the cases in it, (ii) the enabling computing and software environment, and (iii) three practical applications. The prototype is presently being implemented in the Architectural Space Laboratory (ASL) in the Department of Architecture at ETh Zurich.

title Non-photorealistic rendering : A critical examination and proposed system
source Middlesex University
summary In the first part of the program the emergent field of Non-Photorealistic Rendering is explored from a cultural perspective. This is to establish a clear understanding of what Non-Photorealistic Rendering (NPR) ought to be in its mature form in order to provide goals and an overall infrastructure for future development. This thesis claims that unless we understand and clarify NPR's relationship with other media (photography, photorealistic computer graphics and traditional media) we will continue to manufacture "new solutions" to computer based imaging which are confused and naive in their goals. Such solutions will be rejected by the art and design community, generally condemned as novelties of little cultural worth ( i.e. they will not sell). This is achieved by critically reviewing published systems that are naively described as Non-photorealistic or "painterly" systems. Current practices and techniques are criticised in terms of their low ability to articulate meaning in images; solutions to this problem are given. A further argument claims that NPR, while being similar to traditional "natural media" techniques in certain aspects, is fundamentally different in other ways. This similarity has lead NPR to be sometimes proposed as "painting simulation" - something it can never be. Methods for avoiding this position are proposed. The similarities and differences to painting and drawing are presented and NPR's relationship to its other counterpart, Photorealistic Rendering (PR), is then delineated. It is shown that NPR is paradigmatically different to other forms of representation - i.e. it is not an "effect", but rather something basically different. The benefits of NPR in its mature form are discussed in the context of Architectural Representation and Design in general. This is done in conjunction with consultations with designers and architects. From this consultation a "wish-list" of capabilities is compiled by way of a requirements capture for a proposed system. A series of computer-based experiments resulting in the systems "Expressive Marks" and "Magic Painter" are carried out; these practical experiments add further understanding to the problems of NPR. The exploration concludes with a prototype system "Piranesi" which is submitted as a good overall solution to the problem of NPR. In support of this written thesis are : - * The Expressive Marks system * Magic Painter system * The Piranesi system (which includes the EPixel and Sketcher systems) * A large portfolio of images generated throughout the exploration
