summary Computational support in the domain of building design is hampered by the need to control generation and search processes both of which are elusive due to the lack of strong domain theories. Case based reasoning paradigm may be useful to overcome some of these difficulties. A case based design system is presented here that enables case adaptation and case combination of design cases to generate new design solutions more efficiently. Some issues in our approach that are different from other projects with similar aims are also discussed.

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.

title Environment – Urban Interface within Urban Growth
source Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) Developments in Design & Decision Support Systems in Architecture and Urban Planning, Eindhoven: Eindhoven University of Technology, ISBN 90-6814-155-4, p. 49-62
summary This work presents the synthesis of a model of urban growth dedicated to accomplish simulations of urban spatial dynamics, based on integrated urban and environmental factors and promoting simultaneity among external and internal growth. The city and surrounding environment are captured and modeled in computational ambient, by application of the centrality / potential model (Krafta, 1994 and 1999), with support of graph theory, cellular automata, GIS and geocomputation. The model assumes the city as a field of opportunities for obtaining income, mediated by the space, which is composed of urban and environmental attributes, that work as attractors or as resistances for the urban growth. The space configuration and the distribution of those attributes generate tensions that differentiate qualitatively and quantitatively the space, through the centrality measure (built with the support of graphs techniques), coming to provoke growth in places with larger potential of development (built with the help of techniques of CA – cellular automata). Growths above environmental thresholds are considered problems, generated and overcome in the same process of production of the urban space. Iterations of that process offer a dynamic behaviour to the model, allowing to observe the growth process along the time. The model presents several possibilities: a) urban - natural environment integration; b) internal and external growth integration; c) variety in the scale; d) GIS integration and geocomputation; e) user interface; f) calibration; g) theoretical possibilities; and h) practical possibilities.

title A Design Assistant for Environmental Optimisation of Buildings
doi https://doi.org/10.52842/conf.ecaade.1994.x.u0s
source The Virtual Studio [Proceedings of the 12th European Conference on Education in Computer Aided Architectural Design / ISBN 0-9523687-0-6] Glasgow (Scotland) 7-10 September 1994, pp. 247
summary The dual function of the Environmental Design Assistant which we have developed is to act firstly as a teaching aid and secondly as a design aid. In terms of it's role as a design assistant it is similar in nature to the application described by Papamichael, K, in Novitski, B. J. (1993). However, the work described here forms part of an overall strategy to develop a user friendly design assistant across the spectrum of Architectural design disciplines: this is one particular strand of the project. One aim embodied in the development of the environmental design assistant has been the pragmatic one of the production and refining of a tool to perform environmental assessments of buildings in accordance with the British recommendations made in BREEAM (Building Research Establishment Energy Assessment Method). In this respect the assistant allows for the consequences of design decisions to be readily assessed and then for those decisions to be modified. The Assistant has undergone a series of refinements to make it more user-friendly, efficient and appropriate as an Architectural design aid; and this has been the second aim of the project. The project has acted as a vehicle for the application of design principles applied to the presentation, information structuring and navigation associated with Hypermedia and Multimedia products. We are applying the kind of good design principles which have been summarised well by Schulmeister, R. (1994). These principles include Ariadne's Thread (paths for navigation), Lost in Hyperspace (backward navigation), More-than-browsing (interaction) and Tutoring (providing feedback to the user). Adoption of such principles is, we believe, essential in order to realise the potential of Hypermedia tools. The principal development tool for the work has been SuperCard. This has been used in conjunction with a range of other software including ArchiCad and Intellidraw and a range of image grabbing devices.

title Base de datos de la arquitectura moderna de la ciudad de Maracaibo 1920-1990 [Database of the Modern Architecture of the City of Maracaibo 1920-1990]
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 The Inventor Mentor: programming Object-oriented 3D graphics with Open Inventor
source Release 2 Addison Wesley
summary The Inventor Mentor introduces graphics programmers and application developers to Open Inventor, an object-oriented 3D toolkit. Open Inventor is a library of objects and methods used for interactive 3D graphics. Although it is written in C++, Open Inventor also includes C bindings. For the sake of brevity, the examples included in this book are in C++. All C++ examples, as well as equivalent examples written in C, are available on-line. If you are new to the C++ language, see Appendix A, "An Introduction to Object-Oriented Programming for C Programmers," to help you understand the references to classes, subclasses, and other object-oriented concepts used throughout this book. If you are using the C application programming interface, also see Appendix B, "An Introduction to the C API." This book describes how to write applications using the Open Inventor toolkit. The Inventor Toolmaker, a companion book for the advanced programmer, describes how to create new Inventor classes and how to customize existing classes. The Inventor Mentor contains the following chapters: * Chapter 1, "Overview," provides a general description of Open Inventor concepts and classes and how Inventor relates to OpenGL and the X Window System. * Chapter 2, "An Inventor Sampler," presents a short program that creates a simple object. This program is then modified to show the use of important Inventor objects: engines, manipulators, and components. * Chapter 3, "Nodes and Groups," introduces the concept of a scene graph and shows how to create nodes and combine them into different kinds of groups. * Chapter 4, "Cameras and Lights," describes the camera nodes used to view a scene and the light nodes that provide illumination. * Chapter 5, "Shapes, Properties, and Binding," describes how to create both simple and complex shapes and how to use property nodes, including material, draw style, and lighting model nodes. Binding materials and surface normals to shape nodes is also explained. * Chapter 6, "Text," shows the use of 2D and 3D text nodes. * Chapter 7, "Textures," describes how to apply textures to the surfaces of objects in a scene. * Chapter 8, "Curves and Surfaces," explains how to use NURBS curves and surfaces. * Chapter 9, "Applying Actions," describes how operations are applied to an Inventor scene graph. Actions include OpenGL rendering, picking, calculating a bounding box, calculating a transformation matrix, writing to a file, and searching the scene graph for certain types of nodes. * Chapter 10, "Handling Events and Selection," explains how Inventor receives events from the window system. It also describes how the selection node manages a selection list and performs highlighting. * Chapter 11, "File Format," describes Inventor's interchange file format, used for reading files into Inventor, writing files out from Inventor, and data exchanges such as copy and paste. * Chapter 12, "Sensors," describes how Inventor sensors watch for certain types of events and invoke user-supplied callback functions when these events occur. * Chapter 13, "Engines," describes how you can use Inventor engines to animate parts of a scene graph, or to create interdependencies among the nodes in the graph. * Chapter 14, "Node Kits," introduces node kits, a convenient mechanism for creating groups of related Inventor nodes. Each node kit contains a catalog of nodes from which you select the desired nodes. * Chapter 15, "Draggers and Manipulators," describes how to use draggers and manipulators, which are special objects in the scene graph that respond to user events. Manipulators are nodes with field values that can be edited directly by the user. * Chapter 16, "Inventor Component Library," shows how to use Inventor's Xt components, which are program modules with a built-in user interface for changing the scene graph interactively. It also Chapter 17, "Using Inventor with OpenGL," discusses how to use Inventor with the OpenGL Library.

title Graphical Knowledge Interfaces: The Extensive and Intensive Useof Precedent Data Bases in Architecture and Urban Planning
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Space syntax' is a family of techniques for the analysis of architectural and urban space which can be used both in research and design mode. This means, for example, that a redevelopment area in an urban context can be researched using space syntax models which can then be turned round and used as the basis for design idea of a 'graphical knowledge interface' (GM) is a further development of this in feeding research into design. It starts from the important role that the analysis and comparison of 'precedents', that is, cases with some similarity of the design problem in hand, often play in design. In a GM, 'precedents' which have already been researched using the space syntax methodology and which are relevant to a particular design problem - say a set of urban areas or a set of housing estates - can be brought into the modelling technique, so that the designer has on hand not simply a space syntax model of the problem in hand but an intelligent 'precedent' in the form of graphical and statistical representations which can be manipulated and interrogated during the design process, in much the same way as discussion of precedent are currently brought into design but with much more complex data and much more powerful theoretical tools. GM can be used as intensive mode, in which many different kinds of data - say on land uses, rents, or crime rates - are added to the model of an area, or in extensive mode where the emphasis is on comparing, say, the structures of a large number of urban areas. The GM will be illustrated through a worked example of a recent major urban design project in which the team has participated.

title Built form and urban configuration development simulation
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary The "centrality/potential" model, proposed by Krafta (1994), for configurational development, aims at the simulation of inner city built form growth. This is generally achieved by simulating the uneven distribution of floor area increments, resulting from replacement of old buildings, considered "devalued capital" form new ones. The model considers two main variables - public urban space system and built form - and treats them unevenly; the former is extensively disaggregated whereas the latter is not. This feature enables the model to make just a rough account of intra-urban built form development. The issue of built form simulation is then taken further in the following way: a) Urban built form is disaggregated by types. Buildings are classified by a cross combination of scale, purpose, age and quality standard; b) The city is itself considered as a set of intertwined typologic cities. This means that each unit of public space is identified by its dominant built form type, producing a multilayered-discontinuous city. Each one has its own market characteristics: rentability, technological availability and demand size; c) The market constraints determine which layer-city has priority over the others, as well as each one's size of growth. References to rentability and demand size gives each built form type priorities for development d) Spatial conditions, in the form of particular evaluation of centrality and spatial opportunity measures, regulates the distribution of built form increments and typological succession. Locational values, denoted by centrality and spatial opportunity measures, area differently accounted for in each layer-city simulation. e) Simulation is obtained by "running" the model recursively. Each built form type is simulated separately and in hyerarquical order, so that priority and replacement of built form types is acknowledged properly.
