title	Object representation and reasoning using halfplanes and logic
source	J.S. Gero and F. Sudweeks (eds), Artificial Intelligence in Design '98, Kluwer, Dordrecht, pp. 107-126
summary	Shapes and objects represent important ways with which to perceive and reason about the world. This paper develops a framework which uniformly encompasses both planar and non-planar surfaces to represent graphical objects in three dimensions. Based on the concept of halfspaces this framework allows the representation of volumes as predicates in logic. This representation is applied to demonstrate object concepts associated with reasoning about the topology of objects as individuals as well as groups of objects at the early, conceptual phase of designing. The example shows how both planar and non-planar boundaries of objects are treated uniformly.

title	Conceptual designing as a sequence of situated acts
source	I. Smith (Ed.), Artificial Intelligence in Structural Engineering, Springer, Berlin, pp. 165-177
summary	This paper introduces conceptual designing within an F-B-S framework. It then goes on to describe a number of models of designing before introducing the notions of situatedness and situated acts. The remainder of the paper describes the role of situatedness and situated acts in conceptual designing. It attempts to show that a number of otherwise difficult design phenomena are modelable using situatedness and situated acts. A demonstration example concludes the paper along with some of the research issues this view of designing brings with it.

title	Shape pattern recognition using a computable shape pattern representation
source	J.S. Gero and F. Sudweeks (eds), Artificial Intelligence in Design '98, Kluwer, Dordrecht, pp. 169-188
summary	Properties of shapes and shape patterns are investigated in order to represent shape pattern knowledge for supporting shape pattern recognition. It is based on the notion that shape patterns are classified in terms of similarity of spatial relationships as well as physical properties. Methods for shape pattern recognition are explained and examples from an implementation are presented.

title	SG-Clips: A System to Support the Automatic Generation of Designs From Grammars
source	CAADRIA ‘98 [Proceedings of The Third Conference on Computer Aided Architectural Design Research in Asia / ISBN 4-907662-009] Osaka (Japan) 22-24 April 1998, pp. 445-454
doi	https://doi.org/10.52842/conf.caadria.1998.445
summary	SG-CLIPS is a computer tool that supports the automatic generation of designs from a predefined set of grammar rules that encapsulate the composition principles of a certain style of design. It is an open system that accepts any grammar conforming to the conventions described in this paper. We demonstrate the system through an example and discuss the relation to shape grammars and limitations.

title	Automatic Generation of Layouts of an Utzon Housing System via the Internet
source	Reinventing the Discourse - How Digital Tools Help Bridge and Transform Research, Education and Practice in Architecture [Proceedings of the Twenty First Annual Conference of the Association for Computer-Aided Design in Architecture / ISBN 1-880250-10-1] Buffalo (New York) 11-14 October 2001, pp. 202-211
doi	https://doi.org/10.52842/conf.acadia.2001.202
summary	The article describes how architectural layouts can be automatically generated over the Internet. Instead of using a standard web server sending out HTML pages to browser client, the system described here uses an approach that has become common since 1998, known as three tier client/server applications. The server part of the system contains a layout generator using SPR(s), which stands for “Spatial Production Rule System, String Version”, a standard context- free string grammar. Each sentences of this language represents one valid Utzon house layout. Despite the fact that the system represents rules for laying out Utzon houses grammatically, there are important differences between SPR(s) and shape grammars. The layout generator communicates with Autocad clients by means of an application server, which is analogous to a web server. The point of this project is to demonstrate the idea that many hundreds or thousands of clients can request the generation of all of the Utzon layouts simultaneously over the Internet by the SPR(s) server, but the server never has to keep track when each client requested the generation of all of the layouts, or how many layouts each client has received.

title	From Frank Lloyd Wright to Mondrian: Transforming evolving representations
source	I. Parmee (Ed.), Adaptive Computing in Design and Manufacture, Springer, London, pp. 207-219
summary	If a computer is to create designs with the goal of following a certain style it has to have information about this style. Unfortunately, the most often used method of formal representations of style, shape grammars, does not lend itself to automated implementation. However, It has been shown how an evolutionary system with evolving representation can provide an alternative approach that allows a system to learn style knowledge automatically and without the need for an explicit representation. This paper shows how the applicability of evolved representation can be extended by the introduction of transformations of the representation. One such transformation allows mixing of style knowledge, similar to the cross-breeding of animals of different races, with the added possibility of controlling exactly what features are used from which source. This can be achieved through different ways of mixing representations learned from different examples and then using the new, combined representation to create new designs. In a similar manner, information learned in one application domain can be used in a different domain. To achieve this, either the representation or the genotype-phenotype transformation has to be adapted. The same operations also allow mixing of knowledge from different domains. As an example, we show how style information learned from a set of Mondrian paintings can be combined with style information from a Frank Lloyd Wright window design, to create new window designs. Also, we show how the combined style information can then be used to create three-dimensional objects, showing style features similar to the newly designed windows.

title	Collaborative Architectural Design as a reflective Conversation: an agent facilitated system to support collaborative conceptual design
source	Computing in Architecture / Re-Thinking the Discourse: The Second International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2006), 25-27 April 2006, Sharjah, United Arab Emirates
summary	In this paper, definitions of collaborative design are discussed and understood in terms of a designer’s cognitive collaborations to explore his/her experiential memory for remote idea associations. Based on Schon’s reflective practice theory, Valkenburg and Dorst’s (1998) description of collaborative team designing is adopted as a model for a proposed design conversation system. The design conversation system is aimed at triggering the experiential memory of the designer by associating significant ideas from different design domains to provide different perspectives of a design situation. The paper describes a proposed framework for the design conversation system incorporating computational agents in a blackboard architecture environment.

title	Chaos, Databases and Fractal Dimension of Regional Architecture
source	Computerised Craftsmanship [eCAADe Conference Proceedings] Paris (France) 24-26 September 1998, pp. 267-270
doi	https://doi.org/10.52842/conf.ecaade.1998.267
summary	Modern research on chaos started in the 60's from an incredible finding that simple mathematical equations can model systems as complicated as waterfalls. In the 70's some scientists in the USA and in Europe started to find their way through the chaos. They were dealing with different spheres of science: mathematics, physics, biology, chemistry, physiology, ecology, economy. In the next 10 years? time the term 'chaos' has become generally known in science. Scientists gather in research groups according to their interests as to chaos and secondly according to their scientific specialities. (Gleick 1996) Objects that described chaos were irregular in shape, ripped. In 1975 Benoit Mandelbrot called them fractals. Fractal dimension that described fractal objects was also his invention. Fractal dimension is a way to measure quality: the degree of harshness, uneveness, irregularity of a given object. Carl Bovill (1996) showed how one can use fractal geometry in architecture and designing. This very fact made me try to use fractal geometry to deal with regional architecture. What or who is the degree of regionality of a given object to be for? A specially qualified person is able to state it nearly automatically. However, regionality is in some sense an unmeasurable feature. While dealing with data basis or checking particular projects, creation of procedures of automatic acquiring information concerning regionality is becoming a necessity.

title	A Decision Support System (DSS) for Forward Housing Planning
source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	This paper presents a specification of a Local Housing Strategy Decision Support System (LHS-DSS) (Conceptual and Physical model design). Emphasis throughout the design process is laid on the techniques that provide housing planners with accurate rapid assistance during the preparation process of local housing strategy. Relevant knowledge (descriptive, procedural, reasoning) and data about each step of the process, options for each situation as it arises, and a record of decisions made with underlying reasons are provided to system users. Three main components are identified to shape up the LHS-DSS: the language system for addressing housing problems; knowledge system which is responsible for gathering and accumulating the housing knowledge required; and problem processing system (an inquiry system) which produces suitable and effective recommendations to support the strategy preparation process.

title	Java collaborative interface for architectural simulations A case study on wooden ceilings of Krakow
source	International Conference On Conservation - Krakow 2000, 23-24 November 1998, Krakow, Poland
summary	Concern for the architectural and urban preservation problems has been considerably increasing in the past decades, and with it the necessity to investigate the consequences and opportunities opened for the conservation discipline by the development of computer-based systems. Architectural interventions on historical edifices or in preserved urban fabric face conservationists and architects with specific problems related to the handling and exchange of a variety of historical documents and representations. The recent development of information technologies offers opportunities to favour a better access to such data, as well as means to represent architectural hypothesis or design. Developing applications for the Internet also introduces a greater capacity to exchange experiences or ideas and to invest on low-cost collaborative working platforms. In the field of the architectural heritage, our research addresses two problems: historical data and documentation of the edifice, methods of representation (knowledge modelling and visualisation) of the edifice. This research is connected with the ARKIW POLONIUM co-operation program that links the MAP-GAMSAU CNRS laboratory (Marseilles, France) and the Institute HAiKZ of Kraków's Faculty of Architecture. The ARKIW programme deals with questions related to the use of information technologies in the recording, protection and studying of the architectural heritage. Case studies are chosen in order to experience and validate a technical platform dedicated to the formalisation and exchange of knowledge related to the architectural heritage (architectural data management, representation and simulation tools, survey methods, ...). A special focus is put on the evolution of the urban fabric and on the simulation of reconstructional hypothesis. Our contribution will introduce current ARKIW internet applications and experiences: The ARPENTEUR architectural survey experiment on Wie¿a Ratuszowa (a photogrammetrical survey based on an architectural model). A Gothic and Renaissance reconstruction of the Ratusz Krakowski using a commercial modelisation and animation software (MAYA). The SOL on line documentation interface for Kraków's Rynek G_ówny. Internet analytical approach in the presentation of morphological informations about Kraków's Kramy Bogate Rynku Krakowskiego. Object-Orientation approach in the modelling of the architectural corpus. The VALIDEUR and HUBLOT Virtual Reality modellers for the simulation and representation of reconstructional hypothesis and corpus analysis.

title	The use of genetic programming for applications in the field of spatial composition
source	International Conference on Generative Art
summary	Architectural design teaching using computers has been a preoccupation of CECA since 1991. All design tutors provide their students with a set of models and ways to form, and we have explored a set of approaches including cellular automata, genetic programming ,agent based modelling and shape grammars as additional tools with which to explore architectural ( and architectonic) ideas.This paper discusses the use of genetic programming (G.P.) for applications in the field of spatial composition. CECA has been developing the use of Genetic Programming for some time ( see references ) and has covered the evolution of L-Systems production rules( coates 1997, 1999b), and the evolution of generative grammars of form (Coates 1998 1999a). The G.P. was used to generate three-dimensional spatial forms from a set of geometrical structures .The approach uses genetic programming with a Genetic Library (G.Lib) .G.P. provides a way to genetically breed a computer program to solve a problem.G. Lib. enables genetic programming to define potentially useful subroutines dynamically during a run .* Exploring a shape grammar consisting of simple solid primitives and transformations. * Applying a simple fitness function to the solid breeding G.P.* Exploring a shape grammar of composite surface objects. * Developing grammarsfor existing buildings, and creating hybrids. * Exploring the shape grammar of abuilding within a G.P.We will report on new work using a range of different morphologies ( boolean operations, surface operations and grammars of style ) and describe the use of objective functions ( natural selection) and the "eyeball test" ( artificial selection) as ways of controlling and exploring the design spaces thus defined.

title	New functionality for computer-aided conceptual design: the displacement feature
source	Design Studies 19 (1), pp. 81-102
summary	Conceptual design using conventional 3D CAD systems is a controversial issue among industrial designers. Although one can produce complex, accurate, finished 3D models using these CAD systems, it is still difficult to use them during early, creative product design. In this paper, a method is described that allows the design of protrusions and depressions in sculptured surfaces in a flexible and interactive manner. Through interviews with industrial designers, the basic requirements for support of such functionality during conceptual design have been formulated. An implemented method based upon these requirements has been extensively evaluated by industrial designers, and these evaluations show that industrial designers find this functionality extremely useful during conceptual shape design.

title	Concept formation in design
source	Knowledge-Based Systems 10(7-8): 429-435
summary	This paper presents a computationally tractable view on where simple design concepts come from by proposing a paradigm for the formation of design concepts based on the emergence of patterns in the representation of designs. It is suggested that these design patterns form the basis of concepts. These design patterns once learned are then added to the repertoire of known patterns so that they do not need to be learned again. This approach uses the notion called the loosely-wired brain. The paper elaborates this idea primarily through implemented examples drawn from the genetic engineering of evolutionary systems and the qualitative representation of shapes and their multiple representations.

title	Collaborative Conceptual Modeling Using the SKETCH Framework
source	Proceedings of IASTED International Conference on Computer Graphics and Imaging, 154-158
summary	This paper introduces NetSketch, an application that supports distributed conceptual design by providing tools for modelessly creating, manipulating and viewing 3D models in a shared virtual space. Inherent problems exist with collaborative design tools because of the simultaneous group interaction required for users to smoothly and effectively work together in the same virtual space. With NetSketch, we provide solutions to these problems by providing a fast and direct gesture-based user interface, a set of visual effects that better enable a user's awareness of operations done by other participants, and a set of tools for enhancing visual communication between participants.

title	Computational Geometry in C
source	Cambridge: Cambridge University Press
summary	The first edition of this book is recognised as one of the definitive sources on the subject of Computational Geometry. In fact, O'Rourke has a long history in the field, has published many papers on the subject and is responsible for the computer graphics algorithms newsgroup which is where all computer geometers meet to discuss their ideas and problems. Typical problems discussed include how a polygon can be represented, how to calculate its area, how to detect if two polygons intersect and how to calculate the convex hull of a polygon. This leads onto more complex issues such as motion planning and seeing if a robot is able navigate from point x to point y without bumping into objects. The algorithms for these (and other) problems are discussed and many are implemented. In addition, many of the ideas are also discussed from the point of view of three and more dimensions. The only disappointment is that many problems are posed as questions at the end of the chapters and, as far as I could see, you cannot get the answers in the forms of a lecturer's supplement. This is fine in academia but not a lot of use for the commercial world. Due to the range of problems that incorporate computational geometry this book cannot be expected to answer every problem you might have. You will undoubtedly need access to other textbooks but I have been using the first edition of this book for many years and the second edition is a welcome addition to my bookshelf. If I was only allowed one computational geometry book then it would undoubtedly be this one.

doi	https://doi.org/10.52842/conf.caadria.1998.375
summary	Designers recognise or make sense of objects in the context "situations" of other things. Design cannot be predicted and you have to be “at a particular set of states” in order to decide what to do. The inability to determine a priori all design states implies that any design process cannot be pre-planned and design actions cannot be pre-defined. Situated learning is based on the notion that knowledge is contextually situated and is fundamentally influenced by the context in which it is used. We propose a situated learning approach in the domain of architectural shapes design. This paper elaborates the concept of situated learning and demonstrates what it produces in the domain of shape semantics.

title	CAD modelling in multidisciplinary design domains
source	I. Smith (Ed.), Artificial Intelligence in Structural Engineering, Springer, Berlin, pp.335-347
summary	In a multidisciplinary design environment, such as the architecture, engineering and construction (AEC) domain, the various designers will have their own views, concepts and representations of design objects, making communication in a CAD environment a complex task. This paper demonstrates that by taking into consideration the concepts of function and purpose such multiple views and representations can be accomodated. The representation of the functional properties of design objects and their purpose is the underlying basis for the formation of different representations and the coordination of these representations. The paper puts forward definitions for function and purpose which allow for the representation of these properties of a design object and for interdisciplinary communication and integration in a CAD environment.

source	Timmermans, Harry (Ed.), Fourth Design and Decision Support Systems in Architecture and Urban Planning Maastricht, the Netherlands), ISBN 90-6814-081-7, July 26-29, 1998
summary	Nowadays, most of building managers (e.g., companies, local communities, government agencies) have to face up a common set of problems. For instance, these problems are a deficient knowledge of ancient buildings and networks (e.g., gas, water), an inefficient management of green spaces, ora lack of communication between users (e.g., technical staff, suppliers, building end users). In addition, building and spaces to be managed may be shared among several distant areas. LAMIH works aim to achieve methodologies and computer tools for building management andassociated logistic. These works include two aspects we present in this paper:- a methodological one: the establishment of a project business plan, applied to building and logistic management,- a computer aspect: the design and implementation of a decision and management support system, the Geographical and Logistical Information System (G.L.I.S.). The project business plan includes the creation of a task force which has to lead the project and the description of the project plan.The G.L.I.S. is a software set which uses shared database. In particular, this set allows the different users to:- manage a patrimony as a whole, with the help of a Geographical Information System,- manage buildings and networks,- improve communication and logistic aspects with the help of a groupware tool. We present the achievement of these methodology and tools as part of a particular area: theUniversity of Valenciennes which is shared among four towns. The project takes into account existing buildings and those to be built, spaces which separates them, and the relationships betweenthe four different sites of the University. A task force is created as well as a specialised service, the Building Management Department. This department represents an interface between the task force,the LAMIH, and a centre of Information Technologies in construction (CERTIC) which is created as part of the SCENIC project (Support Centres Network for IT in Construction, Esprit project 21772).
