summary	The course on CAAD at the KU Leuven is part of the course on design methodology and theory from which it is the most recent and natural extension. Attached to this course a series of assignments has been developed which bring the students in 45 hours to a non-trivial level of acquaintance with CAAD. Our assignments are primarily directed towards practice. They are built on top of AutoCAD to which we have added in-house developments in order to focus on specific pedagogical goals within a very limited time. After a general introduction on Windows (file management) and AutoCAD (basics) students make the following assignments (main pedagogical goals in between brackets). colophon (working with blocks), detail (2D-drawing, hatching, editing), facade design using a built-in system of proportion (slides, scriptfile), extraction (linking alphanumerical and graphical entities), container (level of detail, icon menus, viewports), surface modelling (modelling 3D-objects with surfaces), fractal tree (recursion in Autolisp), solid modelling (Leicester engineering building), lighting (integration of drawing and computation of illumination levels), pressure lines in an arc (interactive design of an arc), demos. The paper presents and comments these assignments and shows results from the last 2 years.

title	DESIGN BY COMPETITION: LOOKING AT COMPETITION ARCHITECTURE THROUGH TIME
source	Full-Scale Modeling in the Age of Virtual Reality [6th EFA-Conference Proceedings]
summary	We have seen an increase in design competitions for delivery of public buildings. Architectural groups such as the AIA or RIBA often call for a jury dominated by architects. A series of studies of a highly publicized design competition (Peter Eisenman's Wexner Center for the Visual Arts) show the building as a functional and "aesthetic" failure for the public. Some may argue that this is only a short-term appraisal, and that eventually the aesthetic statement will come into favor. To the question of whether architects (the experts) lead public tastes over time, we only have anecdotal evidence. Otherwise, there has been consistent findings of differences between what architects like and what the public likes. How can we look at long-term trends? This paper discusses two historiographic studies of competition architecture through history. One looks at the record of "masterpiece" buildings derived from frequency of reference in books and encyclopedias, and then tallies how many of those "masterpieces" result from competitions. Because of potential flaws in generalizing from these numbers, a second study has architects and non-architects judge photos of competition winning and competition losing designs from a 100-year period. The results show that both groups preferred more losers to winners. This suggests a need for an alternative model for design competition juries.

title	Ivy: Bringing a Weighted-Mesh Representations to Bear on Generative Architectural Design Applications
doi	https://doi.org/10.52842/conf.acadia.2016.140
source	ACADIA // 2016: POSTHUMAN FRONTIERS: Data, Designers, and Cognitive Machines [Proceedings of the 36th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-77095-5] Ann Arbor 27-29 October, 2016, pp. 140-151
summary	Mesh segmentation has become an important and well-researched topic in computational geometry in recent years (Agathos et al. 2008). As a result, a number of new approaches have been developed that have led to innovations in a diverse set of problems in computer graphics (CG) (Sharmir 2008). Specifically, a range of effective methods for the division of a mesh have recently been proposed, including by K-means (Shlafman et al. 2002), graph cuts (Golovinskiy and Funkhouser 2008; Katz and Tal 2003), hierarchical clustering (Garland et al. 2001; Gelfand and Guibas 2004; Golovinskiy and Funkhouser 2008), primitive fitting (Athene et al. 2004), random walks (Lai et al.), core extraction (Katz et al.) tubular multi-scale analysis (Mortara et al. 2004), spectral clustering (Liu and Zhang 2004), and critical point analysis (Lin et al. 20070, all of which depend upon a weighted graph representation, typically the dual of a given mesh (Sharmir 2008). While these approaches have been proven effective within the narrowly defined domains of application for which they have been developed (Chen 2009), they have not been brought to bear on wider classes of problems in fields outside of CG, specifically on problems relevant to generative architectural design. Given the widespread use of meshes and the utility of segmentation in GAD, by surveying the relevant and recently matured approaches to mesh segmentation in CG that share a common representation of the mesh dual, this paper identifies and takes steps to address a heretofore unrealized transfer of technology that would resolve a missed opportunity for both subject areas. Meshes are often employed by architectural designers for purposes that are distinct from and present a unique set of requirements in relation to similar applications that have enjoyed more focused study in computer science. This paper presents a survey of similar applications, including thin-sheet fabrication (Mitani and Suzuki 2004), rendering optimization (Garland et al. 2001), 3D mesh compression (Taubin et al. 1998), morphin (Shapira et al. 2008) and mesh simplification (Kalvin and Taylor 1996), and distinguish the requirements of these applications from those presented by GAD, including non-refinement in advance of the constraining of mesh geometry to planar-quad faces, and the ability to address a diversity of mesh features that may or may not be preserved. Following this survey of existing approaches and unmet needs, the authors assert that if a generalized framework for working with graph representations of meshes is developed, allowing for the interactive adjustment of edge weights, then the recent developments in mesh segmentation may be better brought to bear on GAD problems. This paper presents work toward the development of just such a framework, implemented as a plug-in for the visual programming environment Grasshopper.

title	The Building Design Advisor
doi	https://doi.org/10.52842/conf.acadia.1996.085

summary	The Building Design Advisor (BDA) is a software environment that supports the integrated use of multiple analysis and visualization tools throughout the building design process, from the initial, schematic design phases to the detailed specification of building components and systems. Based on a comprehensive design theory, the BDA uses an object-oriented representation of the building and its context, and acts as a data manager and process controller to allow building designers to benefit from the capabilities of multiple tools. The BDA provides a graphical user interface that consists of two main elements: the Building Browser and the Decision Desktop. The Browser allows building designers to quickly navigate through the multitude of descriptive and performance parameters addressed by the analysis and visualization tools linked to the BDA. Through the Browser the user can edit the values of input parameters and select any number of input and/or output parameters for display in the Decision Desktop. The Desktop allows building designers to compare multiple design alternatives with respect to any number of parameters addressed by the tools linked to the BDA. The BDA is implemented as a Windows-based application for personal computers. Its initial version is linked to a Schematic Graphic Editor (SGE), which allows designers to quickly and easily specify the geometric characteristics of building components and systems. For every object created in the SGE, the BDA supplies “smart” default values from a Prototypical Values Database (PVD) for all non-geometric parameters required as input to the analysis and visualization tools linked to the BDA. In addition to the SGE and the PVD, the initial version of the BDA is linked to a daylight analysis tool, an energy analysis tool, and a multimedia Case Studies Database (CSD). The next version of the BDA will be linked to additional tools, such as a photo-accurate rendering program and a cost analysis program. Future versions will address the whole building life-cycle and will be linked to construction, commissioning and building monitoring tools.

title	The generation of form using an evolutionary approach
source	J.S. Gero and F. Sudweeks (eds), Artificial Intelligence in Design Ì96, 643-662
summary	Design is a purposeful knowledge-based human activity whose aim is to create form which, when realized, satisfies the given intended purposes.1 Design may be categorized as routine or non-routine with the latter further categorized as innovative or creative. The lesser the knowledge about existing relationships between the requirements and the form to satisfy those requirements, the more a design problem tends towards creative design. Thus, for non-routine design, a knowledge-lean methodology is necessary. Natural evolution has produced a large variety of forms well-suited to their environment suggesting that the use of an evolutionary approach could provide meaningful design solutions in a non-routine design environment. This work investigates the possibilities of using an evolutionary approach based on a genotype which represents design grammar rules for instructions on locating appropriate building blocks. A decomposition/aggregation hierarchical organization of the design object is used to overcome combinatorial problems and to maximize parallelism in implementation.

title	Automatic Procedures for Bio-Climatic Control
doi	https://doi.org/10.52842/conf.ecaade.1996.029
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 29-40
summary	The experiences illustrated here are related to the new regulation of teaching architecture in Italy and these ones in particular have been concentrated on the technological aspects of teaching architecture. We can consider the evolution of the architect from the individual operator to the manager multi- disciplinary aspects of the building process ( building process manager) as a reality today. Information technology, specifically applied to bio-climatic architecture and environmental control, can be of great importance for this professional role, and for this reason it is very useful to include these topics at the beginning the teaching design process. This paper describes a particular approach to bio-climatic problems of the architectural project. An experimental course has been performed by the second year students of the "Laboratorio di Construzione dell' Architettura", at the School of Architecture of the Second University of Naples, in Aversa. Analysing old and new buildings, they used some flow charts for the evaluation and representation of energetic behaviour of buildings regarding their climatic and geographical environment. In the flow charts the decisions are represented by boxes that allow to determine "rightness index" related to: morphological characters of the site and environment, typology and particular organisation of the inside spaces, shape of building, technological solution of the building "skin". The navigation through the decision boxes is made with simple options like; "winds: protected or exposed site", "shape of building; free, close or cross plane", "presence of trees on the south,; yes or not",; it shows the students the bio-climatic quality of the building and, through numeric value assigned to each option, determines the "weight" of its climatic comfort.

title	Applying CBR to the Teaching of Architectural Design
doi	https://doi.org/10.52842/conf.ecaade.1996.041
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 41-50
summary	This paper presents an approach to the analysis and description of the nature of process knowledge in architectural design, the development of a conceptual model for Galathea, a case-based navigation tool for its support, and the application of this theoretical foundation to the teaching of design to a group of about 100 second-year architecture students. Design is assumed as a globally coherent information, memory and experience-intensive process in which professional skill is the capability to govern a large number of continually evolving variables in the direction of desired change. This viewpoint on design has guided the development of Galathea, the model of a tool aimed at describing architectural design through the description, mapping and management of the complete decision-making path of projects by means of the dynamic representation of the relationship between goals, constraints and the decisions/actions adopted at specific nodes and through the creation of a case-base aimed at the storage, retrieval and adaptation of relevant design moves in similar project contexts. This conceptual model is applied to educational activity at the faculty of Architecture of Milan, with the aim of teaching how to govern a project from the outset considering it as an evolving but coherent map of design moves, which allow the adoption of the correct decisions involving the most disparate types of information, experience and memory, and which altogether conduct to the desired goal. The resolution paths of the students, all applied to the same architecture problem, result in a design move case-base, the further utilisation and interest of which is open to collegial discussion.

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 shape ('configuration'), location and direction of the pattern of potential trips by foot or bicycle can help decision makers and designers:- the shape of such a pattern informs about the potential size of a traffic calming area(such as 30Km-zoning),- the location of such a pattern refers to the user-groups and specific destinations that a urban network should bring in safe reach for dictated groups,- the direction of such a pattern, together with shape and location, points to the best routing to raise the Sustainable Traffic Modal Split or to improve the reach of destinations like a railway-station.The patters can be generated from zip-code's of user-groups with obvious and daily destinations (school-children, rail-passengers). The next step confronts the theoretical pattern with the layout of streets and the traffic flow, mapping or listing (potential) confrontations between cars and the non-motorised modes, a basis for economical investment in traffic-safety.A design can 'model' the analysed pattern(s) to a economic, direct and safe base (cycle or pedestrian) network. In co-operation, the Dutch the traffic consultant "Verkeersadviesbureau Diepens & Okkema" in Delft, The Netherlands and the Faculty of Architecture, Delft University of Technology, in Delft, The Netherlands, develloped the semi-manual design & decision support system "STAR-Analysis"

summary	For many years architects have been improving their tools in order to make their visions most comprehensible to the future customers - investor and building contractor. Not everyone is able to read the technical drawings of the designed building as it requires the spatial imagination to be developed. For such non-professional persons and also because of the innate need of convenience architect has decided to use a machine called computer. With the help of computer technical drawings, axonometries, perspectives and colourful pictures are being created. They show reality in a more or less precise way. Architects eagerly use such methods of presentation as perspective views, that is photographic images of objects which do not yet exist. All of these measures taken are just a kind of advertising. The architect wants to sell his vision in the most accessible way to beat the competition.

title	A Conceptual Model for Concurrent Engineering in Building Design according to Domain Theory
source	Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings (Spa, Belgium), August 18-21, 1996
summary	Concurrent engineering is a design strategy in which various designers participate in a co-ordinated parallel process. In this process series of functions are simultaneously integrated into a common form. Processes of this type ask for the identification, definition and specification of relatively independent design fields. They also ask for specific design knowledge designers should master in order to participate in these processes. The paper presents a conceptual model of co-ordinated parallel design processes in which architectural space is simultaneously defined in the intersection of three systems: a morphological or level-bound system, a functional or domain-bound system and a procedural or phase-bound system. Design strategies for concurrent engineering are concerned with process design, a design task which is comparable to the design of objects. For successfully accomplishing this task, knowledge is needed of the structural properties of objects and systems; more specifically of the morphological, functional and procedural levels which condition the design fields from which these objects emerge, of the series of generic forms which condition their appearance and of the typological knowledge which conditions their coherence in the overall process.

title	CAAD in the Transformability Evaluation of Historical Buildingsof Historical Buildings
doi	https://doi.org/10.52842/conf.ecaade.1996.055
source	Education for Practice [14th eCAADe Conference Proceedings / ISBN 0-9523687-2-2] Lund (Sweden) 12-14 September 1996, pp. 55-58
summary	In the execution of a research, which was intended to identify methods and instruments for transformability evaluation of historical buildings, CAAD was usefully employed in the decision-making process at different levels. From an operative point of view, it was fundamental instruments for the acquisition of typomorphological data inherent to pre-existent buildings. It allowed us to create an archive of information which can be easily and flexibly up-dated. In fact the critical evaluation of these buildings is based on the identification of structural patterns which have characterized the typological evolution of the urban structure, and thus the different historical stratifications have to be carefully catalogued, profoundly analyzed and compared one with the other. CAAD was even more effective during the phase of meta-designing checking concerning the choices effected for conversion of old buildings, since it was possible to prefigure different scenarios according to formulated hypotheses and this gave us the opportunity to evaluate their effective practicability in relation to typo- morphological congruence and logical and formal connection between the old building and new design proposals.

summary	In the paper presented in the last ECAADE conference in Palermo we described a first hypertext for the analysis of ancient buildings. One section of the hypertext was devoted to show diagnostic procedures and specific instrumental tests for building rehabilitation. We can consider that the hypertext represent the best answer to the request of an organised knowledge coming from students of the schools of architecture and public operators. So we describe how the proposed arrangement of the diagnostic tests can become a real operative tool technicians of public agencies and powerful means of building technology knowledge for students too. The diagnostic procedures are related to the specific needs of the architectural design; changing ways to archive the tests are showed. The goal is to allow the architects, operating in the rehabilitation field, to operate the right choice of diagnostic methods to avoid doing many unnecessary, expensive tests.

title	Building community: a new future for architecture education and practice
source	Carnegie Foundation for the Advancement of Teaching
summary	Internships, before and after graduation, are the most essential link connecting students to the world of practice. Yet, by all accounts, internship is perhaps the most troubled phase of the continuing education of architects. During this century, as architectural knowledge grew more complex, the apprenticeship system withered away and schools assumed much of the responsibility for preparing architects for practice. However, schools cannot do the whole job. It is widely acknowledged that certain kinds of technical and practical knowledge are best learned in the workplace itself, under the guidance of experienced professionals. All state accrediting boards require a minimum period of internship-usually about three years-before a person is eligible to take the licensing exam. The National Council of Architectural Registration Boards (NCARB) allows students to earn up to two years of work credit prior to acquisition of an accredited degree. The Intern Development Program (IDP), launched by NCARB and the American Institute of Architects in 1979, provides the framework for internship in some forty states. The program was designed to assure that interns receive adequate mentoring, that experiences are well-documented, and that employers and interns allocate enough time to a range of educational and vocational experiences to prepare students for eventual licensure. As the IDP Guidelines state, "The shift from school to office is not a transition from theory to pragmatism. It is a period when theory merges with pragmatism.... It's a time when you: apply your formal education to the daily realities of architectural practice; acquire comprehensive experience in basic practice areas; explore specialized areas of practice; develop professional judgment; continue your formal education in architecture; and refine your career goals." Whatever its accomplishments, however, we found broad consensus that the Intern Development Program has not, by itself, solved the problems of internship. Though we found mutually satisfying internship programs at several of the firms we visited or heard about around the country, at many others interns told us they were not receiving the continuing education and experience they needed. The truth is that architecture has serious, unsolved problems compared with other fields when it comes to supplying on-the-job learning experiences to induct students into the profession on a massive scale. Medicine has teaching hospitals. Beginning teachers work in actual classrooms, supported by school taxes. Law offices are, for the most part, in a better financial position to support young lawyers and pay them living wages. The architecture profession, by contrast, must support a required system of internship prior to licensure in an industry that has neither the financial resources of law or medicine, the stability and public support of teaching, nor a network of locations like hospitals or schools where education and practice can be seamlessly connected. And many employers acknowledged those problems. "The profession has all but undermined the traditional relationship between the profession and the academy," said Neil Frankel, FAIA, executive vice president of Perkins & Will, a multinational firm with offices in New York, Chicago, Washington, and London. "Historically, until the advent of the computer, the profession said, 'Okay, go to school, then we in the profession will teach you what the real world is like.' With the coming of the computer, the profession needed a skill that students had, and has left behind the other responsibilities." One intern told us she had been stuck for months doing relatively menial tasks such as toilet elevations. Another intern at a medium-sized firm told us he had been working sixty to seventy hours per week for a year and a half. "Then my wife had a baby and I 'slacked off' to fifty hours. The partner called me in and I got called on the carpet for not working hard enough." "The whole process of internship is being outmoded by economics," one frustrated intern told us. "There's not the time or the money. There's no conception of people being groomed for careers. The younger staff are chosen for their value as productive workers." "We just don't have the best structure here to use an intern's abilities to their best," said a Mississippi architect. "The people who come out of school are really problems. I lost patience with one intern who was demanding that I switch him to another section so that he could learn what he needed for his IDP. I told him, 'It's not my job to teach you. You are here to produce.'" What steps might help students gain more satisfying work opportunities, both during and after graduation?

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	Modeling Designs with Shape Algebras and Formal Logic
source	University of California
summary	A formal, hierarchical model of shape, spatial relations and non-spatial properties is presented, constructed from first principles of geometry, topology and logic. The combination of the two major paradigms used here, shape algebras and logic, is one which has been largely unexplored. The underlying interest is the development of generalized design modeling systems in which the components may be used for a variety of synthesis and recognition problems. The algebras of shape described by Stiny have been shown to be useful in the generation and analysis of designs. The generality of their representations, their non-reliance upon predetermined structure, and their use in combination provide a richness of expression lacking in more traditional representations. The use of formal logic as a specification tool for modeling spatial relations is investigated here. Logic has proven itself useful as a programming and specification tool, providing advantages over traditional procedural programming methods. Among those is the ability to specify the knowledge to be encapsulated in a model without the need to specify data manipulation procedures. It is argued that specification in logic provides a natural method of development. The model is developed by extending the formalisms of shape algebras with the use of logic to make more precise, generalized, parametric definitions of shape and spatial relations than has been previously possible. The value of such a model is demonstrated by the use of these generalized spatial relations for solving typical problems in the fields of geographic information systems and architecture. The advantages of the representations used over more traditional 'kit-of-parts' models is also illustrated.

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

summary	An implementation of a cellular automation is presented that allows the simulation of the behaviour of building components under diverse environment conditions. The tool has a wide range of applications because of the generality of its structure. The object on which it operates is represented as a set of cells each of which is defined, besides its geometrical dimension and position, by a set of variables and parameters. The work it performs consists in computing transitions from a state to another, i.e. the values variables and parameters take in each cell under the action of external agents and of internal laws of interaction between self As an example of its use an application is shown analysing the thermal behaviour of the connection of a curtain wall to a concrete floor.

title	A Volumetric Method for Building Complex Models from Range Images
source	Stanford University
summary	A number of techniques have been developed for reconstructing surfaces by integrating groups of aligned range images. A desirable set of properties for such algorithms includes: incremental updating, representation of directional uncertainty, the ability to fill gaps in the reconstruction, and robustness in the presence of outliers. Prior algorithms possess subsets of these properties. In this paper, we present a volumetric method for integrating range images that possesses all of these properties. Our volumetric representation consists of a cumulative weighted signed distance function. Working with one range image at a time, we first scan-convert it to a distance function, then combine this with the data already acquired using a simple additive scheme. To achieve space efficiency, we employ a run-length encoding of the volume. To achieve time efficiency, we resample the range image to align with the voxel grid and traverse the range and voxel scanlines synchronously. We generate the final manifold by extracting an isosurface from the volumetric grid. We show that under certain assumptions, this isosurface is optimal in the least squares sense. To fill gaps in the model, we tessellate over the boundaries between regions seen to be empty and regions never observed. Using this method, we are able to integrate a large number of range images (as many as 70) yielding seamless, high-detail models of up to 2.6 million triangles.

title	Communication in the building industry: a strategy for implementing electronic information
source	Eindhoven University of Technology
summary	Information Technology in general and electronic communication in particular influence organizational structures. New communication media will change communication processes and business processes. To be able to analyze the influences of the new communication media, a clear view is required of the information flow and the information contents during a building project. Given this view, the question can be answered whether the business process and business organization fit the actual information needs. From the information flow frequency and the information contents, the most appropriate storage structure and transfer medium can be determined. The goal of this thesis is to create a formal description of the information exchange process during a building project, to provide the clear view as stated above.

title	A Design & Decision Support System Proposal for Housing
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 subject of this study is to develop an information management system integrating all the related specialists and sources of information virtually from all related fields in building sector (housing) of Turkey; including design, production, construction, marketing, research. The application field has been chosen as housing for having a contribution to the existing housing problem. Although the subject of architecture is one : "the building", the specialists taking place during the lifetime of a building (from design, to destruction) are numerous. Moreover the links between practitioners, academicians, industry are missing Conventional methods, technology are expensive, time consuming. and insufficient to establish and maintain a healthy coordination between these contributors (mainly the design team and all the other related persons, institutions etc.). This has a strong negative effect on the concepts of "wholeness " and "integrity". The result is a built environment which is lacking significant qualities, while the money has been spent is even much more than required for a proper result. This means the loss of a considerable amount of resources. Especially in a country, which has to build thousands of houses each year, for low income groups, the efficient use of the limited sources becomes more essential. Though the potential user range of the system may include constructors, contractors, building element / material producers and retailers, surveyors, institutions, universities, the main user is aimed to be the architect. The system is aimed to support designers to deal with "complexity" without neglecting the concept of "wholeness". Within the study, the problems which became a stimulus for the development of this system will be investigated. The philosophical base, structure and the possible advantages of the proposal will be discussed.
