title Fractal Cities - A Geometry of Form and Function
source Academic Press, London
summary Fractal Cities is a pioneering study of the development and use of fractal geometry for understanding and planning the physical form of cities, showing how this geometry enables cities to be simulated through computer graphics. It shows how cities evolve and grow in ways that at first sight appear irregular, but which, when understood in terms of fractals, illustrate an underlying order that reveals their complexity and diversity. The book contains sixteen pages of stunning computer graphics and explanations of how to construct them, as well as new insights into the complexity of social systems. The authors provide a gentle and intelligible introduction to fractal geometry as well as an exciting visual understanding of the form of cities, thus providing one of the best introductions to fractal geometry available for non-mathematicians and social scientists. Fractal Cities can be used as a text for courses on geographic information systems, urban geography, regional science and fractal geometry. Planners and architects will also find that there are many aspects of fractal geometry in this book relevant to their own interests. Furthermore, those involved in fractals and chaos, computer graphics, and systems theory will find important methods and examples that are germane to their work.

title The Virtual Cathedral - An Essay about CAAD, History and Structure
doi https://doi.org/10.52842/conf.ecaade.1995.355

summary The Old Cathedral of Santa Maria in Vitoria is the most representative building of the Gothic style in the Basque Country. Built during the XIV century, it has been closed to the cult in 1994 because of the high risk of collapse that presents its structure. This closure was originated by the structural analysis that was entrusted to the University of the Basque Country in 1992. The topographic works developed in the Cathedral to elaborate the planimetry of the temple revealed that many structural elements of great importance like arches, buttresses and flying buttresses were removed, modified or added along the history of Santa Maria. The first structural analysis made in the church suggested that the huge deformations showed in the resistant elements, specially the piers, were originated by interventions made in the past. A deep historical investigation allowed us to know how the Cathedral was built and the changes executed until our days. With this information, we started the elaboration of a virtual model of the Cathedral of Santa Maria. This model was introduced into a Finite Elements Method system to study the deformations suffered in the church during its construction in the XIV century, and the intervention made later in the XV, XVI and XX centuries. The efficiency of the virtual model simulating the geometry of the Cathedral along history allowed us to detect the cause of the structural damage, that was finally found in many unfortunate interventions along time.

summary Fractal geometry provides a powerful tool to explore the world of non-integer dimensions. Very short programs, easily comprehensible, can generate an extensive range of shapes and colors that can help us to understand the world we are living. This shapes are specially interesting in the simulation of plants, mountains, clouds and any kind of landscape, from deserts to rain-forests. The environment design, aleatory or conditioned, is one of the most important contributions of fractal geometry to CAAD. On a small scale, the design of fractal textures makes possible the simulation, in a very concise way, of wood, vegetation, water, minerals and a long list of materials very useful in photorealistic modeling.

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.

title Towards a Free-form Transformable Structure - A critical review for the attempts of developing reconfigurable structures that can deliver variable free-form geometries

summary In continuation of our previous research (Hussein, et al., 2017), this paper examines the kinetic transformable spatial-bar structures that can alter their forms from any free-form geometry to another, which can be named as Free-form transformable structures (FFTS). Since 1994, some precedents have been proposed FFTS for many applications such as controlling solar gain, providing interactive kinetic forms, and control the users' movement within architectural/urban spaces. This research includes a comparative analysis and a critical review of eight FFTS precedents, which revealed some design and technical considerations, issues, and design and evaluation challenges due to the FFTS ability to deliver infinite unpredictable form variations. Additionally, this research presents our novel algorithmic framework to design and evaluate the infinite form variations of FFTS and an actuated prototype that achieved the required movement. The findings of this study revealed some significant design and technical challenges and limitations that require further research work.

title Aesthetic Evolutionary Design with Data Flow Networks
source International Conference on Generative Art
summary For a little over a decade, software has been created which allows for the design of visual content by aesthetic evolutionary design (AED) [3]. The great majority of these AED systems involve custom software intended for breeding entities within one fairly narrow problem domain, e.g., certain classes of buildings, cars, images, etc. [5]. Only a very few generic AED systems have been attempted, and extending them to a new design problem domain can require a significant amount of custom software development [6][8]. High end computer graphics software packages have in recent years become sufficiently robust to allow for flexible specification and construction of high level procedural models. These packages also provide extensibility, allowing for the creation of new software tools. One component of these systems which enables rapid development of new generative models and tools is the visual data flow network [1][2][7]. One of the first CG packages to employ this paradigm was Houdini. A system constructed within Houdini which allows for very fast generic specification of evolvable parametric prototypes is described [4]. The real-time nature of the software, when combined with the interlocking data networks, allows not only for vertical ancestor/child populations within the design space to be explored, but also allows for fast "horizontal" exploration of the potential population surface. Several example problem domains will be presented and discussed. References: [1] Alias | Wavefront. Maya. 2000, http://www.aliaswavefront.com [2] Avid.

title Shape deposition manufacturing
source Vienna University of Technology
summary This thesis addresses the issue of rapidly and automatically fabricating functional metal parts directly from CAD models. A newly developed process called Shape Deposition Manufacturing (SDM) is introduced. The process is based on the concept of layered manufacturing in SFF, but uses separate deposition and shaping steps to create a layer. Three dimensionally shaped layers are created using 5-axis CNC machining, to achieve the required geometric accuracy for fully functional shapes. Thermal deposition technologies (thermal spraying, welding) are used to achieve the required material properties. A novel, droplet based deposition process, microcasting, has been developed, to create well- bonded, high-strength material, while minimising the heat input into previously shaped layers. To create layers with a true three dimensional geometry, more detailed building strategies, than used by conventional SFF processes, are required by the SDM process. A CAD based planning system, which addresses these issues by decomposing a solid model of a part into layers and manufacturable, fully three dimensional segments is described. An automated testbed facility installed at Carnegie Mellon's Shape Deposition Laboratory is discussed, and shows the feasibility of automating the process. The microcasting process is explained in detail and its performance in the SDM environment is evaluated. Different strategies and material combinations for the support structure have been developed and are presented with detailed descriptions of several building strategies for parts with various complexity and material quality. Material properties of structures created by the SDM process are evaluated. Problems affecting the accuracy and material integrity of SDM created structures, which mainly involve the buildup of thermal stresses during material deposition, are identified and opened for future research. Finally, various parts, with different complexity, have been built with the SDM process, to show the feasibility and performance of the process. Building time and material usage are evaluated and compared to conventional SFF processes

title Craft and Geometry in Architecture: An Experimental Design Studio Using the Computer
doi https://doi.org/10.52842/conf.acadia.1994.171
source Reconnecting [ACADIA Conference Proceedings / ISBN 1-880250-03-9] Washington University (Saint Louis / USA) 1994, pp. 171-176
summary Craft is one of the main aspects of architecture that accounts for its strong corporeal presence. The Computer used as a geometry machine lacks such tectonics. The predominant means for bringing a sense of materiality to its geometric constructions is through rendering, and in this respect the computer is not significantly different from geometric drawing. One need only recall the beautifully rendered drawings of the Beaux-Arts for a comparison. With the rise of modern architecture such 'paper' architecture was voraciously denounced in the cause of relating architectural production more closely with crafted production. Even now the interest in craft has persisted despite postmodern criticism. Therefore, a means for bringing a greater sense of craft to computer-aided design seems desirable. The architectural studio discussed in this paper was initiated partly for this purpose by intentionally confronting the computer's proclivity to move its users away from craft toward geometry, while at the same time taking advantage of its capabilities as a geometry machine. Craft can best be understood by practicing it. Consider, for example, the use of a chisel in woodwork. As one applies force with it, one can feel the resistance of the material. Carving with the grain feels differently than carving against or across it. Carving a piece of maple feels differently than carving a piece of pine. If one presses too hard on the chisel or does not hold it at the precise angle, there is a great risk of creating an unwanted gouge. Gradually with practice the tool feels as if it is an extension of the hand that holds it. it becomes an extension of the body. One can feel the physical qualities of the wood through it. Like a limb of the body its presence can become transparent and one can learn about what one feels through it. It can imprint a memory in the mind that comes to the brain, not through the eyes alone, but through the tactile senses. On the other hand it is tiring to use a chisel for an extended period of time. One's body begins to ache and, as the body tires, the risks of making an unwanted mistake increase. Furthermore, because a tool becomes wedded to the body, it is almost impossible to use more than one tool at a time unless they are being used in conjunction with one another as one might use two limbs of the body together. On a computer one can never 'feel' an object, the image of which is on the screen, in the same manner that one can feel with a chisel the material upon which one is working. One becomes particularly aware of this when creating a 3D computer model of a hand tool. One wants to hold it, not just look at it. Thus the artifice of the object created by means of the computer becomes very apparent, because the 'tool' has not yet taken on the qualities of a tool, although it has taken on the appearance of one.

title Computer-generated physical modelling in the early stages of the design process
source Automation in Construction 11 (3) (2002) pp. 303-311
summary This paper illustrates some of the opportunities arising from the introduction of computer-generated physical modelling1 in the early stages of the architectural design process. The use of this technology in the design process differs from previous research and practise in that it looks at the use of computer-generated physical modelling recursively in design process rather than as a means to create a final presentation model [W.J. Mitchell, M. McCullough, Digital Design Media, Van Nostrand Reihnold, New York, 1994]. Previous research in the field by the author identified recursive strategy in the design process as the area in which computer-generated physical modelling offers unique opportunities to the designer. Three unique advantages in the use of computer-generated physical modelling technology are illustrated by three case studies. These advantages are: (1) understanding kinetic design, (2) understanding design involving complex geometry and (3) understanding design at the interface with the human body.

title A Visualization Model for External Shading Devices Performance at the Early Design Stage
source Second Design and Decision Support Systems in Architecture & Urban Planning (Vaals, the Netherlands), August 15-19, 1994
summary Windows are used for the visual connection between indoors and outdoors, ventilation and daylight of our interiors and for the reduction of our heating energy through solar energy utilization. This solar energy, however, is often so intense that counter measures should be taken in order to maintain comfortable indoor conditions. Air conditioning is one counteraction. In order to reduce the cooling loads, it is highly recommended to use shading devices. When shading devices are applied in combination with the glass they can modify the thermal effect of windows to a very great extent. The most effective shading devices are exterior types such as overhang, fins and exterior venetian blind. The effectiveness of an external shading device depends on its geometry, sun path, and the orientation of the building. These factors are interrelated dynamically, it is extremely difficult to predict intuitively how the shadow is cast by the external shading device on the window. Due to the inherent complexity of calculation for shadow casting, building designers to fail often integrate them into energy-efficient building design. Since computer graphics can be a powerful visual communication tool, the above problem might be solved through a computerized graphical interface in the early design stage. The research described in this paper involves the development of a computer program which aims the following objectives: (1) to facilitate the description of a external shading device's geometry through an integrated graphic input model, (ii) to simulate the relationship of external shading devices and shadows based on sun path, the orientation of building, (iii) to visualize the shadow casting by shading devices, and (iv) to provide designers with possible solutions to create energy-efficient external shading device for a specific building.

title Form and Performance in Intelligent CAAD Systems for Early Stages in Solar Design Building
source Technion, Faculty of Architecture and Town Planing, Haifa
summary Great care should be taken at the initial design stages to determine the principles and solution schemes for climate and energy-conscious buildings. The present study deals with supporting the designer's efforts at the early stages to lay down the appropriate principles for a conceptual and geometric design of energy-preserving buildings, which are also thermally comfortable and adapted to local climatic conditions. For years, especially during the last decade, important data concerning climate-conscious construction has been compiled, but the information has not been utilized by designers, due to its inaccessibility. It is significant, though, that solutions based on this knowledge could be found and assessed at the preliminary design steps. A correct climate-conscious design conceived at the initial stages may guarantee that during later phases of the project's development no problems calling for essential and drastic changes in the basic design will crop up. The meaning of such changes at later stages may require sometimes a redesigning of the entire project. It is vital, therefore, to understand at the pre-conceptual phase, what are the correct climatic-solar design strategies which satisfy the requirements of the local conditions, and enable the attainment of thermal comfort conditions, while consuming the least possible energy. The present study proposes a computer-aided passive solar design system (PASYS) which enables the handling of entire designing process, and its general, conceptual aspects, as well as the preliminary designing steps and their particular, practical aspects. The system is based both on a knowledge base which stores the existing information concerning solar-climatic construction in the form of rules of thumb, and on precise procedural models which enable finding solutions suited to the local climatic conditions. The proposed system is an intelligent CAAD system which equips the designer who is aware of the constraints of climate and energy, with a tool to achieve a better design. PASYS was developed as a universal system to deal with the various activities involved in the initial – pre-conceptual and conceptual - design stages. The system supports the following design activities of each stage of this kind: analysis, synthesis, documentation, assessment and decision making. It is capable of analyzing given conditions, thus helping the designer understand which are the significant preliminary design stages that have a bearing on thermal comfort conditions in a given climate. The system is also capable of proposing solutions corresponding with the particular design phase, and assess their adequacy. These solutions take into account the constraints determined both by the designer and by the system itself, owing to the knowledge base it contains. The system can also document the various solutions that have been found and selected, so that may be further developed at later stages. This documentation is carried out by a graphic interface, developed as part of the system, as well as by an interface devised for existing CAD software. This study highlights the interaction between form and performance. The system is able to assess the performance of a proposed design by considering a given geometry (form), or viceversa, it is able to recommend a solution that can deliver desired and required performances. The study comprises three parts: (a.) Development of the conceptual model of a knowledge based design process. (b.) Further development of the initial stages of the afore mentioned process, including the pre-conceptual and conceptual stages. (c.) Demonstration of the mode of work with the PASYS system. // The first part of the study deals with the definition of the design process, the definition of the various design steps and their characteristics, and the definition of the activities involved in each design step. This part of the work also presents the kinds of knowledge bases affecting the design process, and shows how this knowledge is an inseparable part of the design process. The second part deals with the development of the initial design stages - the pre-conceptual and the conceptual - which are based on knowledge. This part also contains compiled knowledge that is relevant to the design stage, and a knowledge storage and retrieval method that was developed so as to make the knowledge available and accessible on demand. This part further presents precise procedural methods, developed to find solutions adapted to the specific given conditions, and to precisely assess the performance of the proposed solution. A case in point is the module of the SHADING system which enables a precise assessment of the mutual shading of buildings, and an examination of the exposure of the southern elevation to the sun, which is necessary in order to determine the effective solar absorption area in a proposed project in given environment conditions. The third part of the study demonstrates the solar-climatic design process put into action and supported by the system that was developed. This system enables the designer, even at the preliminary design stages, to determine which properties relating to local climatic conditions he will introduce into the building. This important, seemingly natural act, is usually performed during more advanced stages, when it might generate significant changes in the design, at a juncture when changes are hard to make. A PASYS-aided design environment ensures that from the beginning of the designing process, the project will be designed correctly and efficiently as far as energy is concerned.

summary Space simulation is a technique employed by architects, urban designers, environmental psychologists and other related specialists. It is used for academic and research purposes, as an aid to evaluate the impact that the built environment or that to be built would yield in potential or real users. Real Scale Model is organized as one of the models which represents more reliable spatial characteristics in space simulations. However, it is necessary to know the ecological validity of the simulations carried out, that is the degree in which laboratory results could be taken as reliable and representative of real situations. In order to discover which variables of the model used are relevant so that their perception results ecologically valid in respect to reality, a research has been designed in which simulations of specific spaces are appraised both in real space and in the real scale model. The results of both evaluations were statistically analyzed and it shows no significative differences in psychological impressions between the evaluation of real spaces and real scale model. These ecological validation of the real scale model could be of great use to estimate the validity of the results obtained in spaces simulated in the laboratory.

summary Lately there has been a good deal of emphasis on the early stages of the design process, particularly by developers of computer aids and quantitative design models for both evaluation and generation of designs in a variety of domains. Yet, there is little understanding of the early design-process. While the early design process as manifested by human designers need not be the sole basis of the description of this phase, it certainly represents and important kernel of knowledge, especially for those who are interested in developing models, systems or merely interfaces for such systems. This paper focuses on the characterization of the psychology of the early design phase in architecture. It is described in terms of the general design strategies and problem solving tactics used; and is contrasted against some of the process characteristics that

summary Several studies have discussed the limitations of the available CAAD tools and have proposed solutions [Brown and Novitski 1987, Brown 1990, Degelman and Kim 1988, Schuman et al 1988]. The lack of integration between the different tasks that these programs address and the design process is a major problem. Schuman et al [1988] argued that in architectural design many issues must be considered simultaneously before the synthesis of a final product can take place. Studies by Brown and Novitski [1987] and Brown [1990] discussed the difficulties involved with integrating technical considerations in the creative architectural process. One aspect of the problem is the neglect of technical factors during the initial phase of the design that, as the authors argued, results from changing the work environment and the laborious nature of the design process. Many of the current programs require the user to input a great deal of numerical values that are needed for the energy analysis. Although there are some programs that attempt to assist the user by setting default values, these programs distract the user with their extensive arrays of data. The appropriate design tool is the one that helps the user to easily view the principal components of the building design and specify their behaviors and interactions. Data abstraction and information parsimony are the key concepts in developing a successful design tool. Three different approaches for developing an appropriate CAAD tool were found in the literature. Although there are several similarities among them, each is unique in solving certain aspects of the problem. Brown and Novitski [1987] emphasize the learning factor of the tool as well as its highly graphical user interface. Degelman and Kim [1988] emphasize knowledge acquisition and the provision of simulation modules. The Windows and Daylighting Group of Lawrence Berkeley Laboratory (LBL) emphasizes the dynamic structuring of information, the intelligent linking of data, the integrity of the different issues of design and the design process, and the extensive use of images [Schuman et al 19881, these attributes incidentally define the word hypermedia. The LBL model, which uses hypermedia, seems to be the more promising direction for this type of research. However, there is still a need to establish a new model that integrates all aspects of the problem. The areas in which the present research departs from the LBL model can be listed as follows: it acknowledges the necessity of regarding the user as the center of the CAAD tool design, it develops a model that is based on one of the high level theories of human-computer interaction, and it develops a prototype tool that conforms to the model.

title Spatial Analysis for Museum Design

summary The paper describes how a specially written customisation of AutoCAD enables students of Architecture to use the method of spatial analysis called Space Syntax developed by Professor Bill Hillier of the Bartlett School of Architecture, London, to examine a number of existing museums, to compare the findings against other criteria, and to draw conclusions about the strategy adopted in museum design. Simple interactive graphics enable plans to be entered and compared, so that they may be evaluated during the design process, with decisions supported by objective tests. This improves both design decisions and the learning process.

title A run time exchange of component information between CAD and object models: A standard interface
source The Int. Journal of Construction IT 2(2), pp. 37-52
summary Integrated computer aided design could only occur in engineering once CAD systems could represent physical features and components rather than graphical primitives. In most dedicated CAD systems, the knowledge of a complete component exists only for the duration of each drawing command and the data stored in the database is simply a set of graphic primitives. This paper proposes an approach for real time information transfer from and to CAD systems based on a high level object representation of the design drawing. Drawing components are automatically identified and represented in an object hierarchy that reflects the 'part-of' relation between the various components including building spaces. Such hierarchies transfer an industry standard CAD system i.e. AutoCAD, into a high level object oriented system that can communicate with external applications with relative ease.

title Determining the impact of cad drafting tools on the building delivery process
source The Int. Journal of Construction IT 2(1), pp.1-8
summary Computer aided design is intended to change the way design and construction are carried out. at a minimum, this implies savings realized in terms of time spent and improvement of the quality of designs produced. to test this idea, we hypothesized that computer aided drafting and design operations may be instrumental in reducing the number of change orders issued and help control cost overruns by improving the accuracy of construction documents. we compared change orders in projects designed in the conventional media against ones developed with computers. we found that there is evidence supporting our hypothesis. furthermore, in the process of investigating this question, we found that computer applications to improve the management of existing building information (as-built drawings, building system related information, and the like) represent even more critical needs than those that can reduce change orders through more accurate design drawings.

summary This paper describes a 10 week, 3rd year architectural design studio, taught by the author, that explored the use of film and video techniques in the design process. The exploration was of (1) the potential of recently available personal computer software and hardware for image and video capture, manipulation and recording, and (2) the potential for application of video, informed by film theory, in the early stages of architectural design.

title APPLICATION OF FULL-SCALE MODELLING IN VIETNAM: AN OUTLINE FOR DISCUSSION
source Beyond Tools for Architecture [Proceedings of the 5th European Full-scale Modeling Association Conference / ISBN 90-6754-375-6] Wageningen (The Netherlands) 6-9 September 1994, pp. 59-70
summary This paper discusses the possibility of applying full-scale modelling in Vietnam, a non-western so called developing country. It deals with two main questions: 1) Is the application of full-scale modelling to be restricted to the West only? 2) what are the possibilities, constraints and fields of application - with attention to the methodological validity and technical solution for full-scale modelling in Vietnam? It is argued that since full-scale modelling is based on people-environment interaction, it should, in principle, apply to studies about people–environment relation anywhere on earth. On the methodological validity, it is discussed that application of full-scale modelling in Vietnam faces similar methodological problems as encountered in European applications (such as people's behaviour in experiment, ability to understand the abstraction of models, etc.) although at another level as this paper will make clear. However, it would be needed to design a modelling kit that is of low costs and adapted to the availability of local materials and suitable for the climatic condition of Vietnam. Two fields of application are projected as most applicable in Vietnam: modelling in architectural education and research investigation. Application for user's participation in the design process will depend on the development of building policy in the country.

source Beyond Tools for Architecture [Proceedings of the 5th European Full-scale Modeling Association Conference / ISBN 90-6754-375-6] Wageningen (The Netherlands) 6-9 September 1994, pp. 71-82
summary The Italian simulation laboratory carries out most of its activity within the experimental programmes promoted by the Ministry of Works. Within this context, we conducted studies based on the topics of EUROPAN competitions for young architects, built models based on EUROREX programme's projects and analyzed experimental projects directly financed by the Ministry (mainly restoration projects).
