title The Combination of Design Media and Design Creativity _ Conventional and Digital Media
source CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007

summary Creativity is always interested in many fields, in particular, creativity and design creativity have many interpretations (Boden, 1991; Gero and Maher, 1992, 1993; Kim, 1990; Sternberg, 1988; Weisberg, 1986). In early conceptual design process, designers used large number of sketches and drawings (Purcell and Gero, 1998). The sketch can inspire the designer to increase the creativity of the designer’s creations(Schenk, 1991; Goldschmidt, 1994; Suwa and Tversky, 1997). The freehand sketches by conventional media have been believed to play important roles in processes of the creative design thinking(Goldschmidt, 1991; Schon and Wiggins, 1992; Goel, 1995; Suwa et al., 2000; Verstijnen et al., 1998; Elsas van and Vergeest, 1998). Recently, there are many researches on inspiration of the design creativity by digital media(Liu, 2001; Sasada, 1999). The digital media have been used to apply the creative activities and that caused the occurrenssce of unexpected discovery in early design processes(Gero and Maher, 1993; Mitchell, 1993; Schmitt, 1994; Gero, 1996, 2000; Coyne and Subrahmanian, 1993; Boden, 1998; Huang, 2001; Chen, 2001; Manolya et al. 1998; Verstijinen et al., 1998; Lynn, 2001). In addition, there are many applications by combination of conventional and digital media in the sketches conceptual process. However, previous works only discussed that the individual media were related to the design creativity. The cognitive research about the application of conceptual sketches design by integrating both conventional and digital media simultaneously is absent.

title A Network-based Kit-of-parts Virtual Building System
source CAAD Futures 1997 [Conference Proceedings / ISBN 0-7923-4726-9] München (Germany), 4-6 August 1997, pp. 691-706
summary This paper describes an experimental browser / modeler which will allow the user to collect and assemble virtual kit-of-parts components from "component libraries" located on the Internet (such as manufacturer's databases) and assemble them into a virtual representation of a building. The fully assembled virtual building will provide a basis for ordering and manufacturing actual components and preparing for construction. The browser will allow the designer to affect a limited degree of remote fabrication at real manufacturing facilities, and facilitate eventual interface with built in sensors and actuators. The browser will manipulate and display interactive three dimensional objects using Virtual Reality Modeling Language (VRML). Upon assembly, actual components will have sensors built into them for providing data about the real building, which could be viewed during a walkthrough of the virtual building by clicking on parts of the model. The virtual building will work as a remote facility management tool for monitoring or controlling various architectural devices attached to the real building (such as electrically driven louvers, HVAC systems, appliances, etc.).

title Digital Architecture in CAD studio and Internet-based competition
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 Architectural design has been changing because of the vast and creative use of computer in different ways. From the viewpoint of designing itself, computer has been used as drawing tools in the latter phase of design (Mitchell 1977; Coyne et al. 1990), presentation and simulation tools in the middle phase (Liu and Bai 2000), and even critical media which triggers creative thinking in the very early phase (Maher et al. 2000; Liu 1999; Won 1999). All the various roles that computer can play have been adopted in a number of professional design corporations and so-called computer-aided design (CAD) studio in schools worldwide (Kvan 1997, 2000; Cheng 1998). The processes and outcomes of design have been continuously developing to capture the movement of the computer age. However, from the viewpoint of social-cultural theories of architecture, the evolvement of design cannot be achieved solely by designers or design processes. Any new idea of design can be accepted socially, culturally and historically only under one condition: The design outcomes could be reviewed and appreciated by critics in the field at the time of its production (Csikszentmihalyi 1986, 1988; Schon and Wiggins 1992; Liu 2000). In other words, aspects of design production (by designers in different design processes) are as critical as those of design appreciation (by critics in different review processes) in the observation of the future trends of architecture.Nevertheless, in the field of architectural design with computer and Internet, that is, so-called computer-aided design computer-mediated design, or internet-based design, most existing studies pay more attentions to producing design in design processes as mentioned above. Relatively few studies focus on how critics act and how they interact with designers in the review processes. Therefore, this study intends to investigate some evolving phenomena of the interaction between design production and appreciation in the environment of computer and Internet.This paper takes a CAD studio and an Internet-based competition as examples. The CAD studio includes 7 master's students and 2 critics, all from the same countries. The Internet-based competition, held in year 2000, includes 206 designers from 43 counties and 26 critics from 11 countries. 3 students and the 2 critics in the CAD studio are the competition participating designers and critics respectively. The methodological steps are as follows: 1. A qualitative analysis: observation and interview of the 3 participants and 2 reviewers who join both the CAD studio and the competition. The 4 analytical criteria are the kinds of presenting media, the kinds of supportive media (such as verbal and gesture/facial data), stages of the review processes, and interaction between the designer and critics. The behavioral data are acquired by recording the design presentation and dialogue within 3 months. 2. A quantitative analysis: statistical analysis of the detailed reviewing data in the CAD studio and the competition. The four 4 analytical factors are the reviewing time, the number of reviewing of the same project, the comparison between different projects, and grades/comments. 3. Both the qualitative and quantitative data are cross analyzed and discussed, based on the theories of design thinking, design production/appreciation, and the appreciative system (Goodman 1978, 1984).The result of this study indicates that the interaction between design production and appreciation during the review processes could differ significantly. The review processes could be either linear or cyclic due to the influences from the kinds of media, the environmental discrepancies between studio and Internet, as well as cognitive thinking/memory capacity. The design production and appreciation seem to be more linear in CAD studio whereas more cyclic in the Internet environment. This distinction coincides with the complementary observations of designing as a linear process (Jones 1970; Simon 1981) or a cyclic movement (Schon and Wiggins 1992). Some phenomena during the two processes are also illustrated in detail in this paper.This study is merely a starting point of the research in design production and appreciation in the computer and network age. The future direction of investigation is to establish a theoretical model for the interaction between design production and appreciation based on current findings. The model is expected to conduct using revised protocol analysis and interviews. The other future research is to explore how design computing creativity emerge from the process of producing and appreciating.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 136-143.
summary The hybridization of architectural, biological and robotic agencies Situated in the field of architectural biodesign, InterspeciesForms explores a closer relationship between the fungus Pleurotus ostreatus and the designer in the creation of form. The intention of hybridizing mycelia’s agency of growth with architectural design intention is to generate novel, non-indexical crossbred designed outcomes that evolve preconceived notions of architectural form. Mycelium are threadlike fibrous root systems made up of hyphae, that form the vegetative part of a fungus (Jones 2020). Known as the hackers of the wood wide web (Simard 1997) mycelia form complex symbiotic relationships with other species that inhabit our earth. Michael Lim states “Fungi redefine resourcefulness, collaboration, resilience and symbiosis” (Lim 2022, p. 14). When wandering around the forest to connect with other species or searching for food, fungi form elaborate and entangled networks by spreading their hyphal tips. Shown in Figure 1, this living labyrinth results in the aesthetic formation of an intricate web. Due to the organisms ability to determine the most effective direction of growth, communicate with its surrounding ecosystem, and connect with other species, fungi are indeed an intelligent species with a unique aesthetic that must not be ignored. In drawing on these concepts, I refer to the organism’s ability to search for, tangle, and digest its surroundings as ‘mycelia agency of growth’. It is this specific behavioral characteristic that is the focus of this research, with which I, as the architect, set out to co-create and hybridize with.

source AVOCAAD First International Conference [AVOCAAD Conference Proceedings / ISBN 90-76101-01-09] Brussels (Belgium) 10-12 April 1997, pp. 93-101
summary The existing Caad systems limit designers creativity by constraining them to work with prototypes provided by the system's knowledge base. Most think of computers as drafting machines and consider CAAD models as merely proposals for future buildings. But this kind of thinking (computers as simple drafting machines) seems to be a way without future. New media demands new process and new process demands new media. We have to give some thougt to impact of CAAD on the design process and in which part of it CAAD can add new value. In this paper there will be considered two ways of using of computers. First - creation of architectural form in an architect's mind and projects visualisation with using renderings, animation and virtual reality. In the second part - computer techniques are investigated as a medium of creation. Unlike a conventional drawing the design object within computer has a life of its own. In computer space design and the final product are one. Computer creates environments for new kind of design activities. In fact, many dimensions of meaning in cyberspace have led to a cyberreal architecture that is sure to have dramatic consequences for the profession.

title Computer analysis of visual perception - endoscopy without endoscope
source Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary This paper presents a method of using computer animation techniques in order to solve problems of visual pollution of city environment. It is our observation that human-inducted degradation of city environmental results from well - intentioned but inappropriate preservation actions by uninformed designers and local administration. Very often, a local municipality administration permits to build bad-fitting surroundings houses. It is usually connected with lack of visual information's about housing areas of a city, its features and characteristics. The CAMUS system (Computer Aided Management of Urban Structure) is being created at the Faculty of Architecture of Bialystok Technical University. One of its integral parts is VIA - Visual Impact of Architecture. The basic element of this system is a geometrical model of the housing areas of Bialystok. This model can be enhanced using rendering packages as they create the basis to check our perception of a given area. An inspiration of this approach was the digital endoscopy presented by J. Breen and M. Stellingwerff at the 2nd EAEA Conferences in Vienna. We are presenting the possibilities of using simple computer programs for analysis of spatial model. This contribution presents those factors of computer presentation which can demonstrate that computers achieve such effects as endoscope and often their use be much more efficient and effective.

title Repairing CAD models
source Proceedings of IEEE Visualizationí97, pp. 363-370
summary We describe an algorithm for repairing polyhedral CAD models that have errors in their B-REP. Errors like cracks, degeneracies, duplication, holes and overlaps are usually introduced in solid models due to imprecise arithmetic, model transformations, designer's fault, programming bugs, etc. Such errors often hamper further processing like finite element analysis, radiosity computation and rapid prototyping. Our fault-repair algorithm converts an unordered collection of polygons to a shared-vertex representation to help eliminate errors. This is done by choosing, for each polygon edge, the most appropriate edge to unify it with. The two edges are then geometrically merged into one, by moving vertices. At the end of this process, each polygon edge is either coincident with another or is a boundary edge for a polygonal hole or a dangling wall and may be appropriately repaired. Finally, in order to allow user- inspection of the automatic corrections, we produce a visualization of the repair and let the user mark the corrections that conflict with the original design intent. A second iteration of the correction algorithm then produces a repair that is commensurate with the intent. Thus, by involving the users in a feedback loop, we are able to refine the correction to their satisfaction.

title Combining different kinds of perspective images in architectural practice.
source Architectural and Urban Simulation Techniques in Research and Education [Proceedings of the 3rd European Architectural Endoscopy Association Conference / ISBN 90-407-1669-2]
summary This paper is about combining photo-, video-, endoscope captured images with handmade or computer generated ones. Practically all optical systems are known to produce more or less curved perspective (spherical or cylindrical) which depends of angle-of-view, and a computer as a rule (as handmade) constructs linear perspective images. To combine them on any media correctly, an operator has to be professional painter or designer, because there is no mathematically determined way to combine them. The author's-made demo-computer program is able to generate spherical perspective of simple spatial constructions. It allows to illustrate mathematically and visually the principles of optical curved perspective, laws of their combination with linear ones and helps to feel how to achieve the accordance with natural visual architectural images.

title RealSpace in QuickTimes: architecture and digitization
source Rotterdam: Nai Publishers
summary Time and space, drastically compressed by the computer, have become interchangeable. Time is compressed in that once everything has been reduced to 'bits' of information, it becomes simultaneously accessible. Space is compressed in that once everything has been reduced to 'bits' of information, it can be conveyed from A to B with the speed of light. As a result of digitization, everything is in the here and now. Before very long, the whole world will be on disk. Salvation is but a modem away. The digitization process is often seen in terms of (information) technology. That is to say, one hears a lot of talk about the digital media, about computer hardware, about the modem, mobile phone, dictaphone, remote control, buzzer, data glove and the cable or satellite links in between. Besides, our heads are spinning from the progress made in the field of software, in which multimedia applications, with their integration of text, image and sound, especially attract our attention. But digitization is not just a question of technology, it also involves a cultural reorganization. The question is not just what the cultural implications of digitization will be, but also why our culture should give rise to digitization in the first place. Culture is not simply a function of technology; the reverse is surely also true. Anyone who thinks about cultural implications, is interested in the effects of the computer. And indeed, those effects are overwhelming, providing enough material for endless speculation. The digital paradigm will entail a new image of humankind and a further dilution of the notion of social perfectibility; it will create new notions of time and space, a new concept of cause and effect and of hierarchy, a different sort of public sphere, a new view of matter, and so on. In the process it will indubitably alter our environment. Offices, shopping centres, dockyards, schools, hospitals, prisons, cultural institutions, even the private domain of the home: all the familiar design types will be up for review. Fascinated, we watch how the new wave accelerates the process of social change. The most popular sport nowadays is 'surfing' - because everyone is keen to display their grasp of dirty realism. But there is another way of looking at it: under what sort of circumstances is the process of digitization actually taking place? What conditions do we provide that enable technology to exert the influence it does? This is a perspective that leaves room for individual and collective responsibility. Technology is not some inevitable process sweeping history along in a dynamics of its own. Rather, it is the result of choices we ourselves make and these choices can be debated in a way that is rarely done at present: digitization thanks to or in spite of human culture, that is the question. In addition to the distinction between culture as the cause or the effect of digitization, there are a number of other distinctions that are accentuated by the computer. The best known and most widely reported is the generation gap. It is certainly stretching things a bit to write off everybody over the age of 35, as sometimes happens, but there is no getting around the fact that for a large group of people digitization simply does not exist. Anyone who has been in the bit business for a few years can't help noticing that mum and dad are living in a different place altogether. (But they, at least, still have a sense of place!) In addition to this, it is gradually becoming clear that the age-old distinction between market and individual interests are still relevant in the digital era. On the one hand, the advance of cybernetics is determined by the laws of the marketplace which this capital-intensive industry must satisfy. Increased efficiency, labour productivity and cost-effectiveness play a leading role. The consumer market is chiefly interested in what is 'marketable': info- and edutainment. On the other hand, an increasing number of people are not prepared to wait for what the market has to offer them. They set to work on their own, appropriate networks and software programs, create their own domains in cyberspace, domains that are free from the principle whereby the computer simply reproduces the old world, only faster and better. Here it is possible to create a different world, one that has never existed before. One, in which the Other finds a place. The computer works out a new paradigm for these creative spirits. In all these distinctions, architecture plays a key role. Owing to its many-sidedness, it excludes nothing and no one in advance. It is faced with the prospect of historic changes yet it has also created the preconditions for a digital culture. It is geared to the future, but has had plenty of experience with eternity. Owing to its status as the most expensive of arts, it is bound hand and foot to the laws of the marketplace. Yet it retains its capacity to provide scope for creativity and innovation, a margin of action that is free from standardization and regulation. The aim of RealSpace in QuickTimes is to show that the discipline of designing buildings, cities and landscapes is not only a exemplary illustration of the digital era but that it also provides scope for both collective and individual activity. It is not just architecture's charter that has been changed by the computer, but also its mandate. RealSpace in QuickTimes consists of an exhibition and an essay.

summary Design is a complex and time consuming process. One way to simplify the design process is to use pre-build blocks for commonly known parts instead of creating them again with CAD. To give the designer an immediate 3D view of the design, designing in virtual reality is a good choice. This paper presents a virtual reality interface tool which allows a user to assemble an architecture structure from a library of pre-built blocks. The library is a distributed client-server database.

doi https://doi.org/10.52842/conf.ecaade.1997.x.h5q
summary This paper considers the role of the computer for detailed design within the wider architectural design process. The central proposition is that parametric modelling software is invaluable for both preliminary and developed design where there is a need for the definition, manipulation and visualisation of complex geometry. The paper begins with a definition of 'parametric design' followed by a consideration of its potential to assist or hinder the designer. A worked example will demonstrate how the elements that make up a model can be referenced to each other using a number of clearly defined constraints, the completed model being changed, modified and regenerated while conforming to pre-set conditions. This will be followed by a report on research into the implications of parametric design modelling applied retrospectively to Jørn Utzon's documented design process for the Sydney Opera House. The study analyses how conventional modelling coped with the manipulation of these forms and compares this with the potential of computer-aided iterative design refinement.

summary The building industry involves a larger number of disciplines, operators and professionals than other industrial processes. Its peculiarity is that the products (building objects) have a number of parts (building elements) that does not differ much from the number of classes into which building objects can be conceptually subdivided. Another important characteristic is that the building industry produces unique products (de Vries and van Zutphen, 1992). This is not an isolated situation but indeed one that is spreading also in other industrial fields. For example, production niches have proved successful in the automotive and computer industries (Carrara, Fioravanti, & Novembri, 1989). Building design is a complex multi-disciplinary process, which demands a high degree of co-ordination and co-operation among separate teams, each having its own specific knowledge and its own set of specific design tools. Establishing an environment for design tool integration is a prerequisite for network-based distributed work. It was attempted to solve the problem of efficient, user-friendly, and fast information exchange among operators by treating it simply as an exchange of data. But the failure of IGES, CGM, PHIGS confirms that data have different meanings and importance in different contexts. The STandard for Exchange of Product data, ISO 10303 Part 106 BCCM, relating to AEC field (Wix, 1997), seems to be too complex to be applied to professional studios. Moreover its structure is too deep and the conceptual classifications based on it do not allow multi-inheritance (Ekholm, 1996). From now on we shall adopt the BCCM semantic that defines the actor as "a functional participant in building construction"; and we shall define designer as "every member of the class formed by designers" (architects, engineers, town-planners, construction managers, etc.).

title Artificial intelligence and networking in integrated building management systems
source Automation in Construction 6 (5-6) (1997) pp. 481-498
summary In recent years the emphasis has moved towards integrating all a building's systems via centralised building management systems (BMS). To provide a more intelligent approach to the facility management, safety and energy control in building management systems (IBMS), this paper proposes a methodology for integrating the data within a BMS via a single multi-media networking technology and providing the BMS with artificial intelligence (AI) through the use of knowledge-based systems (KBS) technology. By means of artificial intelligence, the system is capable of assessing, diagnosing and suggesting the best solution. This paper outlines how AI techniques can enhance the control of HVAC systems for occupant comfort and efficient running costs based on occupancy prediction. Also load control and load balancing are investigated. Instead of just using pre-programmed load priorities, this work has investigated the use of a dynamic system of priorities which are based on many factors such as area usage, occupancy, time of day and real time environmental conditions. This control strategy which is based on a set of rules running on the central control system, makes use of information gathered from outstations throughout the building and communicated via the building's data-bus.

title Matching of freeform curves
source Computer-Aided Design, Vol. 29 (5) (1997) pp. 369-378
summary Freeform parametric curves are extensively employed in various fields such as computer graphics, computer vision, robotics, and geometric modeling. While manyapplications exploit and combine univariate freeform entities into more complex forms such as sculptured surfaces, the problem of a fair or even optimal relativeparameterization of freeforms, under some norm, has been rarely considered. In this work, we present a scheme that closely approximates the optimal relativematching between two or even n given freeform curves, under a user's prescribed norm that is based on differential properties of the curves. This matching iscomputed as a reparameterization of n - 1 of the curves that can be applied explicitly using composition. The proposed matching algorithm is completely automaticand has been successfully employed in different applications with several demonstrated herein: metamorphosis of freeform curves with feature preservations, keyframe interpolation for animation, self-intersection free ruled surface construction, and automatic matching of rail curves of blending surfaces.

summary One of the dominant paradigms in architecture is about its creation: it is done by human designers supported by tools like sketching, drawing or modelling and evaluation tools. The Darwinistic paradigm demands a paradigmatic switch from drawing, modelling and evaluation to the breeding of forms with a much more integrated generation and selecting process embedded in the computer machinery. This means a paradigm switch from a designer as the performer of (sketch, draw or modelling) work to a machine driven creation and selection process of forms with the designer as the supervisor, fully entitled to steer the process in some preferred directions. The designer creates by establishing the evolutionary rules and making choices among the architectural creatures emerging in rapid fire modethrough the synthesis performed by the machine. Natural selection is a Metaphor: in fact the designer plays Nature (or God). The creatures allowed to flourish are not adequate according to laws of Nature, but to the judgement of the designer (or to the designing team).

summary Understanding ‘space’ as a structured and dynamic system can provide us with insight into the central concept in the architectural discourse that so far has proven to withstand theoretical framing (McLuhan 1964). The basis for this theoretical assumption is that space is not a void left by solid matter but instead an emergent quality of action and interaction between individuals and groups with a physical environment (Hillier 1996). In this way it can be described as a parallel distributed system, a self-organising entity. Extrapolating from Luhmann’s theory of social systems (Luhmann 1984), a spatial system is autonomous from its progenitors, people, but remains intangible to a human observer due to its abstract nature and therefore has to be analysed by computed entities, synthetic cognisers, with the capacity to perceive. This poster shows an attempt to use another complex system, a distributed connected algorithm based on Kohonen’s self-organising feature maps – SOM (Kohonen 1997), as a “perceptual aid” for creating geometric mappings of these spatial systems that will shed light on our understanding of space by not representing space through our usual mechanics but by constructing artificial spatial cognisers with abilities to make spatial representations of their own. This allows us to be shown novel representations that can help us to see new differences and similarities in spatial configurations.

summary Design computing has often been considered a subset of computer applications that assist the designer in documenting and analysing complex designs. As one of many areas in which computer applications have beeen developed, design computing has relied on software developers and vendors to implement and market software with the relevant features and utilities to support some aspects of design activity. In this paper we consider design computing as a research area, one in which the results of the research lead to more than additional computer programs and in fact lead to a better understanding of designing and computer support for designing.

doi https://doi.org/10.52842/conf.ecaade.1997.x.j8r
summary This paper reports on the findings of an empirical investigation into the use of the computer as the only design media in solving a design problem. Several 1st and 2nd year students took part in a two week experiment on the use of a CAD programme, AutoCAD 13 and AEC 5.0, to design a studio for a graphic designer.

Prior to the experiment an extensive literature search was carried out to explore the relationship between the design process, visual thinking, conventional sketching (interactive imagery) and Computer Aided Design. Out of this search a number of design variables were identified, developed and then tested through a series of observations and interviews with the students while they were engaged in the design of the Graphic Designer’s Studio. Questionnaires were also administered to students to explore their views on issues including, using CAD instead of conventional tools, design areas where CAD is most effective, and how CAD can improve design skills.

title Shape, Space And Building Element: Development of a Conceptual Object Model for the Design Process
source Challenges of the Future [15th eCAADe Conference Proceedings / ISBN 0-9523687-3-0] Vienna (Austria) 17-20 September 1997
doi https://doi.org/10.52842/conf.ecaade.1997.x.g4l
summary The paper describes the first steps taken in the search for a central object model presenting all possible data, concepts and operations concerning the architectural design process.  From the early design stage, an architectural model can be built on computer.  A central object model of this process is essential: a model describing geometrical shapes, spaces, building elements and user activities, together with all the basic operations these entities can undertake.  The model could provide the necessary information for the performance of tests to assist the designer (energy calculation, stability check, costs ...).  Appropriate interfaces between the object model and existing software packages allow different actors in the design process to make use of the model’s data. First, the conceptual model for CAAD in the design process is described. The second part deals with the methodology used for developing the object model: M.E.R.O.DE (Model-driven Entity-Relationship Object-oriented Development) proves to be a firm base to start our design.  Finally, we present some aspects of the first prototype for such a central object model.
