title	A strategy for complex-curved building design:Design structure with Bi-lateral contouring as integrally connected ribs
source	SIGraDi 2006 - [Proceedings of the 10th Iberoamerican Congress of Digital Graphics] Santiago de Chile - Chile 21-23 November 2006, pp. 465-469
summary	Shapes in designs created by architects such as Gehry Partners (Shelden, 2002), Foster and Partners, and Kohn Peterson and Fox rely on computational processes for rationalizing complex geometry for building construction. Rationalization is the reduction of a complete geometric shape into discrete components. Unfortunately, for many architects the rationalization is limited reducing solid models to surfaces or data on spread sheets for contractors to follow. Rationalized models produced by the firms listed above do not offer strategies for construction or digital fabrication. For the physical production of CAD description an alternative to the rationalized description is needed. This paper examines the coupling of digital rationalization and digital fabrication with physical mockups (Rich, 1989). Our aim is to explore complex relationships found in early and mid stage design phases when digital fabrication is used to produce design outcomes. Results of our investigation will aid architects and engineers in addressing the complications found in the translation of design models embedded with precision to constructible geometries. We present an algorithmically based approach to design rationalization that supports physical production as well as surface production of desktop models. Our approach is an alternative to conventional rapid prototyping that builds objects by assembly of laterally sliced contours from a solid model. We explored an improved product description for rapid manufacture as bilateral contouring for structure and panelling for strength (Kolarevic, 2003). Infrastructure typically found within aerospace, automotive, and shipbuilding industries, bilateral contouring is an organized matrix of horizontal and vertical interlocking ribs evenly distributed along a surface. These structures are monocoque and semi-monocoque assemblies composed of structural ribs and skinning attached by rivets and adhesives. Alternative, bi-lateral contouring discussed is an interlocking matrix of plywood strips having integral joinery for assembly. Unlike traditional methods of building representations through malleable materials for creating tangible objects (Friedman, 2002), this approach constructs with the implication for building life-size solutions. Three algorithms are presented as examples of rationalized design production with physical results. The first algorithm [Figure 1] deconstructs an initial 2D curved form into ribbed slices to be assembled through integral connections constructed as part of the rib solution. The second algorithm [Figure 2] deconstructs curved forms of greater complexity. The algorithm walks along the surface extracting surface information along horizontal and vertical axes saving surface information resulting in a ribbed structure of slight double curvature. The final algorithm [Figure 3] is expressed as plug-in software for Rhino that deconstructs a design to components for assembly as rib structures. The plug-in also translates geometries to a flatten position for 2D fabrication. The software demonstrates the full scope of the research exploration. Studies published by Dodgson argued that innovation technology (IvT) (Dodgson, Gann, Salter, 2004) helped in solving projects like the Guggenheim in Bilbao, the leaning Tower of Pisa in Italy, and the Millennium Bridge in London. Similarly, the method discussed in this paper will aid in solving physical production problems with complex building forms. References Bentley, P.J. (Ed.). Evolutionary Design by Computers.

source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 64-71
summary	Although virtual reality (VR) is a fast-growing field, utilization of its potential within an affordable environment in the early years of architectural education has been limited. Currently, we are in the process of exploring the educational potential of virtual reality in the creation and understanding of space as a set of dynamic volumes that can be experienced. The VR-Desktop initiative is an effort to bring the salient features of projection-based VR to second-year architecture students in a way that is more generally accessible than the many canonical, first-generation, projection-based VR systems. The VR-Desktop has been implemented in the teaching of the architectural design studio in the second year of a fiveyear curriculum, as part of the physical architectural studio. Through the VR-Desktop system in the studio, students immediately start working in an immersive environment. They create space by manipulating solids and voids while evaluating the anthropometric relations of the proposed solution. The students are able to study and test conceptual details in a virtual environment from the very beginning of their architectural design project. In order to assess student perception of the usefulness of various system attributes for diverse tasks, we have begun a usability study. Thirty-five surveys were collected from the students who had used the lab during the two semesters for which the two-screen system was available. Preliminary observations indicate that within the architectural context, virtual reality techniques involving depth perception can convey relevant information to students more efficiently and with less misrepresentation than traditional techniques. This paper suggests that full field of view, motion, stereoscopic vision, and interactivity are possible components of the 3D visualization techniques that are necessary to enhance architectural education

title	Understanding Spatial Information with Integrated 3D Visual and Aural Design Applications
doi	https://doi.org/10.52842/conf.acadia.2002.333
source	Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 333-338
summary	The ability to arrange information graphically in digitally represented Cartesian space offers obviousadvantages over two-dimensional graphical reductions. Adding time to the spatial palette provides adynamic dimension. Cartesian space used for these purposes, however, reinforces an ocular-centricapproach to information delivery. We can include sound in order to seek a sensory balance, therebyimproving cognition and enhancing dimensionality within an ‘information space’, especially for complexmaterial requiring greater interactivity or ‘audience’ participation. Combined visual and audio synthesisoffers multidimensional and multi-sensorial environments that challenge existing linear and twodimensionalpresentation orthodoxies – ‘audience’, for instance, presupposes a lecture to be listened to.This paper presents work in progress investigating the use of sonification as both a thematic andnavigational vehicle in dynamic presentation environments.

title	Strategic Briefing A Conceptual Process Model for Building Design
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	Nowadays building design problems are divided in partial discipline related sub-problems. Through targeted and focused attention to sub problems however the awareness of the whole is lost. Each designparticipant gives his sub-problem first priority. In contrast in the past the master builder saw the whole problem as his problem first. Thus the process of seeing the design problem as a whole, as a result ofprioritizing, considering constraints, or strategizing, is lost in today’s practice, basically because this process is a mental and implicit process, that occurred in the brain of the multi-disciplinary master builder.In most cases it is the task of no one in a design team today. The aim of this paper is modeling this conceptual mental implicit process design using System Theory and Cognitive Psychology, trying to determine the structure of the design problem as it occurs intuitively in the brain. The result will provide us with a mechanism that enables us each time to refine a unique common design problem representation. This leads to more effective use of design team capabilities, and forms an essential basis for organizing efforts toward collaborative solutions. Also some kind of clarity is provided as to how proposed solutions are to be judged.

source	SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 151-154
summary	Despite increasing interest in the functionality and humanization of architecture, scarcely the occupation of buildings are studied and it lacks methods to represent activities in the spaces. By this reason, it proposes a system such integrates simulation of processes and virtual modeling software, to program the behavior of tri-dimensional characters based on the probabilistic evolution of events, testing this approach in the study of emergency services of hospitals. It describes the procedure developed and reflections about temporal representation, demonstrating that modeling of activities allows to suggest functional and spatial improvements.

title	Collaborative design of structures using intelligent agents
source	Automation in Construction 11 (1) (2002) pp. 89-103
summary	The construction industry has a long tradition of collaborative working between the members of a construction project team. At the design stage, this has traditionally been based on physical meetings between representatives of the principal design disciplines. To aid these meetings, the information and communications technologies that are currently available have been utilised. These have yielded some success but are hampered by the problems posed by the use of heterogeneous software tools and the lack of effective collaboration tools that are necessary to collapse the time and distance constraints, within which increasingly global design teams work. In particular, there are very few tools available to support distributed asynchronous collaboration. Distributed artificial intelligence, which is commonly implemented in the form of intelligent agents, offers considerable potential for the development of such tools. This paper examines some of the issues associated with the use of distributed artificial intelligence systems within the construction industry. It describes the potential for the use of agent technology in collaborative design and then goes on to present the key features of an agent-based system for the collaborative design of portal frame structures. An example is presented to demonstrate the working and benefits of the prototype system, which makes a significant contribution by allowing for peer to peer negotiation between the design agents.

title	The spatial discourse of Power Architectures in Kurt Wimmer's film "Equilibrium".
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 1421–1432
summary	This article explores the correlation between the language of cinema and the architectural spatial discourse of power depicted in the film Equilibrium (Wimmer, 2002). This connection is examined through a discursive approach to communication studies. To analyze a specific sequence from the chosen film, a two-stage multimodal analysis was conducted. Initially, the visual analysis method proposed by Kress and Van Leeuwen (2006) designed for the representation of social actors, was employed. Subsequently, in the second stage, sociological and conceptual associations were drawn from the diverse semiotic resources identified in the first phase. The analyzed case revealed several intertextual relationships, among them; Hitler's figure recontextualized as an exemplifying archetype; the panopticon concept representing the spatial power dynamics; the presence of the German zeppelin symbolizing dominance and spreading propaganda through loudspeakers; the religious iconographic influence, its forms and symbols, contributing to a cultural identity inseparable from the history of the Western world.

title	Faculties of Architecture
source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary	In order to be inscribed in the European Architect’s register the study program leading to the diploma ‘Architect’ has to meet the criteria of the EC Architect’s Directive (1985). The criteria are enumerated in 11 principles of Article 3 of the Directive. The Advisory Committee, established by the European Council got the task to examine such diplomas in the case some doubts are raised by other Member States. To carry out this task a matrix was designed, as an independent interpreting framework that mediates between the principles of Article 3 and the actual study program of a faculty. Such a tool was needed because of inconsistencies in the list of principles, differences between linguistic versions ofthe Directive, and quantification problems with time, devoted to the principles in the study programs. The core of the matrix, its headings, is a categorisation of the principles on a higher level of abstractionin the form of a taxonomy of domains and corresponding concepts. Filling in the matrix means that each study element of the study programs is analysed according to their content in terms of domains; thesummation of study time devoted to the various domains results in a so-called ‘profile of a faculty’. Judgement of that profile takes place by committee of peers. The domains of the taxonomy are intrinsically the same as the concepts and categories, needed for the description of an architectural design object: the faculties of architecture. This correspondence relates the taxonomy to the field of design theory and philosophy. The taxonomy is an application of Domain theory. This theory,developed by the authors since 1977, takes as a view that the architectural object only can be described fully as an integration of all types of domains. The theory supports the idea of a participatory andinterdisciplinary approach to design, which proved to be awarding both from a scientific and a social point of view. All types of domains have in common that they are measured in three dimensions: form, function and process, connecting the material aspects of the object with its social and proceduralaspects. In the taxonomy the function dimension is emphasised. It will be argued in the paper that the taxonomy is a categorisation following the pragmatistic philosophy of Charles Sanders Peirce. It will bedemonstrated as well that the taxonomy is easy to handle by giving examples of its application in various countries in the last 5 years. The taxonomy proved to be an adequate tool for judgement ofstudy programs and their subsequent improvement, as constituted by the faculties of a Faculty of Architecture. The matrix is described as the result of theoretical reflection and practical application of a matrix, already in use since 1995. The major improvement of the matrix is its direct connection with Peirce’s universal categories and the self-explanatory character of its structure. The connection with Peirce’s categories gave the matrix a more universal character, which enables application in other fieldswhere the term ‘architecture’ is used as a metaphor for artefacts.

source	SIGraDi 2003 - [Proceedings of the 7th Iberoamerican Congress of Digital Graphics] Rosario Argentina 5-7 november 2003
summary	Hearing and touch may be incorporated into visual representation systems that historically covered creative process, now helped by multimedia. During 2002-2003 we developed an experimental design studio that challenged participants to design architecture from words (using their spelling, pronunciation, location, etc.) and through an inquiry based on the "concept of inwardness". Evoking a word from the association of images and texts as well as seizing its potential tactile and hearing dimensions completed what was a very interactive design process. Such process was utilized to generate images and ideas geared to design/make an "installation" to be displayed at art events.

summary	In this paper, we present two user-centered systems aiming at making easier the modeling ofarchitectural and urban scenes by using two different but complementary approaches. The first oneMArINa, an image-based modeler, allows the user to reconstruct urban scenes from one or moregraphical documents. This method focuses more on reconstructing models and is more dedicated tothe production of 3D sketches. The second modeler, MArCo is a knowledge-based modelercontaining the know-from and know-how on classical architecture. It allows the user to modelclassical architectural scenes verifying automatically all the domain rules. Finally, we show howMArINa and MArCo can cooperate providing the user a tool combining efficiently their respectivecapabilities.

title	Relating to the ‘real’ Perceptions of Computer Aided and Physical Modelling
doi	https://doi.org/10.52842/conf.ecaade.2002.134
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 134-138
summary	Designing - giving form to new objects or environments - is largely a question of anticipating the workings of spatial and material environments, which can become ‘reality’ only by being built. Until ‘realized’ a design is essentially a figment of the designer’s imagination, although his or her ideas may be laid down and conveyed to others via specialized design media. In this way impressions of the design may be shared with clients, colleagues or other ‘actors’ in the design process. Such products of the designer’s imaging process can be relatively abstract or begin to approach - future - reality. Form & Media research can be ‘revealing’, stimulating insights concerning preferences, working processes and the effects of products of the designer’s imagination. In the past ten years we have gained considerable practical experience with both virtual and tangible (scale) models. We have compared different techniques in conference workshops, within educational settings and in our Form & Media research laboratory. The research projects ranged from the development of practical techniques and working methods to protocol analyses of designing architects. This contribution draws comparisons between different computer aided modelling techniques, with an indication of their perspectives, making use of the experience gained from various experiments in an educational context, and will highlight the potentials for different combinations of digital and physical modelling techniques.

title	A Room with a Different View
source	Environmental Simulation - New Impulses in Planning Processes [Proceedings of the 5th European Architectural Endoscopy Association Conference / ISBN 3-922602-85-1]
summary	This contribution documents the developments, results and findings of an experimental design visualisation and presentation exercise entitled ‘A Different View of Delft’. The primary aim of this project was to make students aware of the potentials of the active utilisation of physical models for the sake of designerly enquiry. Furthermore the ambition was to explore new ways of using such model ‘environments’ for the benefit of design communication and presentation. For this exercise a ‘game’ situation with clear constraints and rules was developed beforehand. The students were to work out a proposal for a new exhibition space, as an annex to a – hypothetical – existing museum. The new space was to create a fitting ‘setting’ for a single work of art: Johannes Vermeer’s famous View of Delft. The maximum contours of the new exhibition space were given, along with clear guidelines concerning which walls and roof segments might be (partly) opened. The emphasis lay on the viewer’s ‘approach’ to the painting, its positioning and ‘framing’ in an architectural context. A designerly search involving form and space, the choice of colours and materials and particularly the strategic use of (natural) lighting.

source	Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings Avegoor, the Netherlands), 2002
summary	The present contribution, starting from some considerations developed in environmental planning domain, discusses the representation of lay knowledge in a GIS environment. Two paths of exploration in dealing with representational problems are sketched. The first is concerned with the structuring of an acquired cognitive base and, the other is about the implementation of cognitive routines. In particular the structuring process of a lay cognitive base is discussed starting from recent developments in GIS technologies and information theories. Difficulties and pitfalls, which arouse during a case study related to an environmental planning experience being carried on for a national natural park, are presented. The experimentation work is discussed also in relation with a preliminary attempt of outputs validation carried out with people who, in a preliminary stage, were interviewed in order to acquire lay knowledge.

title	SHARED SPACE’ AND ‘PUBLIC SPACE’ DIALECTICS IN COLLABORATIVE ARCHITECTURAL DESIGN.
source	Proceedings of Collaborative Decision-Support Systems Focus Symposium, 30th July, 2002; under the auspices of InterSymp-2002, 14° International Conference on Systems Research, Informatics and Cybernetics, 2002, Baden-Baden, pg. 27-44.
summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

summary	The present paper describes on-going research on Collaborative Design. The proposed model, the resulting system and its implementation refer mainly to architectural and building design in the modes and forms in which it is carried on in advanced design firms. The model may actually be used effectively also in other environments. The research simultaneously pursues an integrated model of the: a) structure of the networked architectural design process (operators, activities, phases and resources); b) required knowledge (distributed and functional to the operators and the process phases). The article focuses on the first aspect of the model: the relationship that exists among the various ‘actors’ in the design process (according to the STEP-ISO definition, Wix, 1997) during the various stages of its development (McKinney and Fischer, 1998). In Collaborative Design support systems this aspect touches on a number of different problems: database structure, homogeneity of the knowledge bases, the creation of knowledge bases (Galle, 1995), the representation of the IT datum (Carrara et al., 1994; Pohl and Myers, 1994; Papamichael et al., 1996; Rosenmann and Gero, 1996; Eastman et al., 1997; Eastman, 1998; Kim, et al., 1997; Kavakli, 2001). Decision-making support and the relationship between ‘private’ design space (involving the decisions of the individual design team) and the ‘shared’ design space (involving the decisions of all the design teams, Zang and Norman, 1994) are the specific topic of the present article. Decisions taken in the ‘private design space’ of the design team or ‘actor’ are closely related to the type of support that can be provided by a Collaborative Design system: automatic checks performed by activating procedures and methods, reporting of 'local' conflicts, methods and knowledge for the resolution of ‘local’ conflicts, creation of new IT objects/ building components, who the objects must refer to (the ‘owner’), 'situated' aspects (Gero and Reffat, 2001) of the IT objects/building components. Decisions taken in the ‘shared design space’ involve aspects that are typical of networked design and that are partially present in the ‘private’ design space. Cross-checking, reporting of ‘global’ conflicts to all those concerned, even those who are unaware they are concerned, methods for their resolution, the modification of data structure and interface according to the actors interacting with it and the design phase, the definition of a 'dominus' for every IT object (i.e. the decision-maker, according to the design phase and the creation of the object). All this is made possible both by the model for representing the building (Carrara and Fioravanti, 2001), and by the type of IT representation of the individual building components, using the methods and techniques of Knowledge Engineering through a structured set of Knowledge Bases, Inference Engines and Databases. The aim is to develop suitable tools for supporting integrated Process/Product design activity by means of a effective and innovative representation of building entities (technical components, constraints, methods) in order to manage and resolve conflicts generated during the design activity.

title	A Large-Scale Computing Infrastructure for Design Education
doi	https://doi.org/10.52842/conf.ecaade.2002.282
source	Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 282-289
summary	Most departmental computing infrastructure reflects the state of networking technology and available funds at the time of construction, which converge in a preconceived notion of homogeneity of network architecture and usage patterns. The DMAN (Digital Media Access Network) project, a large-scale server and network foundation for The Hong Kong Polytechnic University’s School of Design, was created as a platform that would support a highly complex academic environment while giving maximum freedom to students, faculty and researchers through simplicity and ease of use. As a centralized multi-user computation backbone, DMAN faces an extremely heterogeneous user and application profile, exceeding implementation and maintenance challenges of typical enterprise, and even most academic server set-ups. This paper summarizes the specification, implementation and application of the system while describing its significance for design education in a computational context.

summary	The cyberspace upon physical space forms a new spatial structure to increase the influence on the urban fabric and the concept of space in architecture. Today, digital cities are being developed all over the world. By using a city metaphor, digital cities integrate urban information and create public spaces. How do digital cities directly connect to physical cities and become an imaginable city? Therefore, we argue that a new spatial analysis theory must be established for digital city, comparing with theories of disciplines, to find the explicitly spatial structures and relations in digital city upon physical city.

title	Intelligent approaches for generating assembly drawings from 3-D computer models of mechanical products
source	Computer-Aided Design, Vol. 34 (5) (2002) pp. 347-355
summary	In order to reduce the time of mechanical product design and ensure the high quality of their assembly drawings, this paper develops an intelligent approach for generatingassembly drawings automatically from three-dimensional (3-D) computer assembly models of mechanical products by simulating the experienced human designer's thinkingmode with the aid of computer graphics and knowledge-based expert system. The key issues include the strategies and methods for selecting the necessary views in anassembly drawing, determining necessary sectional views in each view, eliminating the unreasonable projective overlap of the components in each view, and minimizing thenumbers of both the views in an assembly drawing and the sectional views in each view. Based on the approach, corresponding software prototype was developed. Finally, itis demonstrated, from an example of the fixture in a modularized drilling machine, that its assembly drawing was generated successfully using this intelligent softwareprototype.
