title Evolution of Media for Early Design Stages
source Timmermans, Harry (Ed.), Sixth Design and Decision Support Systems in Architecture and Urban Planning - Part one: Architecture Proceedings Avegoor, the Netherlands), 2002
summary In this paper the evolution of media used at early design stages will be considered. In traditional methods of searching and presenting the design idea, the basic tool used was the graphic representation. Implementation of new digital techniques in 60s - 70s focused on the mathematical way ofrepresentation. These methods were “not architect friendly” (lack of graphic representation traditionally used by architects). As a result, the development of methods for digital support of form searching was terminated. The computer was used as a tool for drafting. Creative usage of computers for form searching through sketching on the display was extremely difficult. The computer could be described as an “incompatible pencil”. Only in recent years can we see new efforts in this area ofdesign methodology. Thanks to new technical possibilities we have a new chance for changing the process of designing. New kinds of software and hardware let us use the computer not as a pen, but as a medium. In this paper different new ways of form searching will be considered (from very simple method as the scansketches to very complicated ones, such as the generic algorithms). At the end, the influence of new media on the process of design will be presented.

title Spatial Visualization of abstract Information: A Classification Model for Visual Spatial Design Guidelines in the Digital Domain
source Swiss Federal Institute of Technology, ETH Zurich
summary Visualization of abstract information refers to the design of graphical representations of information that has no simple relation to known concrete or physical forms. Designing visualizations of abstract information requires proposing visual representation for often a large body of data pants. determining a meaningful structure for the complex relations among them and suggesting a method for Interacting with this body of data. Spatial perception plays an Important role for cognitive processing when interacting with abstract information, slice spatially-organized Information can be accessed and operated on rapidly and effortlessly, especially when a spatial arrangement reveals the conceptual organization of Information.

This thesis focuses on aspects of the spatial visual design of abstract information presented as computer-generated. dynamic and interactive images accessible through flat displays. The process of spatial visualization design is shaped by various factors including interactive, perceptual, navigational as well as organizational and metaphorical aspects and as such requires an interdisciplinary approach. Therefore, in researching spatial visual design. it is crucial to use methods facilitating the process of sharing competencies among different disciplines.

In this thesis, we introduce a new classification model accommodating features important in designing effective spatial visualizations of abstract information. To enhance the effectiveness of spatial visualization, this model offers a holistic approach in classifiying spatial Visualization features. As part of the model, we analyze properties already used in architectural representation and other visual design disciplines for spatial presentations as well as investigate their potential usage in digital domains of abstract information. The process of spatial visualization In the digital environment is mostly based on the practical experience of a designer. and therefore the majority of spatial design know-how is heuristic in nature. Based on this assumption, we present a set of guidelines addressing the general problem of spatial design.

The Spalial Design Classificahon Model, Visual Spatial Properties and Spatial Design Guidelines build an extendable infrastructure which becomes a first step towards augmenting the quality of spatial information design- We propose to use this infrastructure as a general blueprint for structuring the exchange of expertise in Interdisciplinary problem-solving processes.

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 Generative Architectural Design and Complexity Theory
source International Conference on Generative Art
summary During the past decades, complexity theory has evolved as a new discipline that provides a broad scientific perspective towards dynamic real-life phenomena, challenging the classical linear worldview as well as simple cause-and-effect-style Newtonian physics. For architects, the advent of this new science offers the challenge as well as the chance to reconsider common design approaches and to invent new strategies based on the new paradigms. The actual application of complexity theory to architectural design, however, results in a fundamental dilemma: How can a reflective, ultimately retrospective body of thought (complexity theory) be applied to prospective design challenges (architecture)? Being part of a current MArch thesis project, the proposed paper focuses on this general dilemma between architectural design and complexity theory and discusses actual as well as potential future generative architectural design approaches involving complexity theory. Generative design strategies commonly apply algorithmic methods and formalisms, which can conveniently produce and deal with high levels of complexity. Complexity describes general properties of a system and can be further dissected into several modes: epistemic, ontological and functional complexity. This taxonomy offers insights into generative design applications, which have mostly focused on a limited set of complexity modes. Besides complexity generated by sheer numbers, aspects like functional or hierarchical complexity offer further perspectives on generative systems, processes and output. Considering these aspects of complexity theory, future challenges to generative architectural design can be predicted.

title Architectural Forms by Abstracting Nature
source International Conference on Generative Art
summary The structures in nature are great lessons for human study. Having been in development for several billion years, only the most successful structural forms have survived. The resourcefulness of material use, the underlying structural systems and the profound capacity to respond to a variety of climatic and environmental forces make natural form tremendous exemplars to human architectures. The wholeness of natural form indicates that the form and forces are always in some sense of equilibrium. In most of natural forms, the quality of equilibrium may be difficult to recognize. However, seashells are one of the natural forms whose functions are simple enough to be approximated by a simple mathematical relationship. The focus of this study was to understand the seashell form as applicable to human architectures. Digital methods are the language to analyze, create, and simulate seashell forms, as well as, suggest a variety of possible architectural forms.

summary Photogrammetry methods have been shown to be useful as a tool for investigation of illuminance distribution and light losses in interiors containing obstruction configurations that approximate to simple rectilinear objects. This work examines the use of photogrammetry to model obstructions having a greater degree of complexity and a case study demonstrates the applicability of the technique to lighting design for a factory. The results confirm that this technology would accelerate the process of incorporating the effect of obstructions in routine lighting analysis and design.

title CAD/CAM Methods in Support of Historic Preservation: A Case Study of the Freeman House by Frank Lloyd Wright
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 52-54
summary Preservationists have an impressive array of digital tools to aid them in documentation and analysis of historic structures. The tools range from near photo-realistic renderings to demonstrate what a “restored” building might have looked like at one specifi c time in history to complex chemical analysis of paint chips and pigments to geographic information systems used as management tools for historic prop er ties. Computer-aided design / computer-aided manufacturing (CAD/CAM) is set of important digital aids in historic preservation efforts. This paper presents a case study of the use of CAD/CAM in support of an effort to restore a textile block house designed by Frank Lloyd Wright. CAD/CAM methods are being employed to help produce a new mold so that new textile blocks can be manufactured that match the existing blocks. An existing textile block mold was digitally scanned, digitally mirrored and edited, and will be fabricated from an aluminum billet to replace a mold that no longer exists. Although seemingly a simple process and well within current technological abilities, the work proved substantially more challenging that initially imagined.

title Perception Aspects in Underground Spaces using Intelligent Knowledge Modeling
source Delft University of Technology
summary The intensification, combination and transformation are main strategies for future spatial development of the Netherlands, which are stated in the Fifth Bill regarding Spatial Planning. These strategies indicate that in the future, space should be utilized in a more compact and more efficient way requiring, at the same time, re-evaluation of the existing built environment and finding ways to improve it. In this context, the concept of multiple space usage is accentuated, which would focus on intensive 4-dimensional spatial exploration. The underground space is acknowledged as an important part of multiple space usage. In the document 'Spatial Exploration 2000', the underground space is recognized by policy makers as an important new 'frontier' that could provide significant contribution to future spatial requirements.In a relatively short period, the underground space became an important research area. Although among specialists there is appreciation of what underground space could provide for densely populated urban areas, there are still reserved feelings by the public, which mostly relate to the poor quality of these spaces. Many realized underground projects, namely subways, resulted in poor user satisfaction. Today, there is still a significant knowledge gap related to perception of underground space. There is also a lack of detailed documentation on actual applications of the theories, followed by research results and applied techniques. This is the case in different areas of architectural design, but for underground spaces perhaps most evident due to their infancv role in general architectural practice. In order to create better designs, diverse aspects, which are very often of qualitative nature, should be considered in perspective with the final goal to improve quality and image of underground space. In the architectural design process, one has to establish certain relations among design information in advance, to make design backed by sound rationale. The main difficulty at this point is that such relationships may not be determined due to various reasons. One example may be the vagueness of the architectural design data due to linguistic qualities in them. Another, may be vaguely defined design qualities. In this work, the problem was not only the initial fuzziness of the information but also the desired relevancy determination among all pieces of information given. Presently, to determine the existence of such relevancy is more or less a matter of architectural subjective judgement rather than systematic, non-subjective decision-making based on an existing design. This implies that the invocation of certain tools dealing with fuzzy information is essential for enhanced design decisions. Efficient methods and tools to deal with qualitative, soft data are scarce, especially in the architectural domain. Traditionally well established methods, such as statistical analysis, have been used mainly for data analysis focused on similar types to the present research. These methods mainly fall into a category of pattern recognition. Statistical regression methods are the most common approaches towards this goal. One essential drawback of this method is the inability of dealing efficiently with non-linear data. With statistical analysis, the linear relationships are established by regression analysis where dealing with non-linearity is mostly evaded. Concerning the presence of multi-dimensional data sets, it is evident that the assumption of linear relationships among all pieces of information would be a gross approximation, which one has no basis to assume. A starting point in this research was that there maybe both linearity and non-linearity present in the data and therefore the appropriate methods should be used in order to deal with that non-linearity. Therefore, some other commensurate methods were adopted for knowledge modeling. In that respect, soft computing techniques proved to match the quality of the multi-dimensional data-set subject to analysis, which is deemed to be 'soft'. There is yet another reason why soft-computing techniques were applied, which is related to the automation of knowledge modeling. In this respect, traditional models such as Decision Support Systems and Expert Systems have drawbacks. One important drawback is that the development of these systems is a time-consuming process. The programming part, in which various deliberations are required to form a consistent if-then rule knowledge based system, is also a time-consuming activity. For these reasons, the methods and tools from other disciplines, which also deal with soft data, should be integrated into architectural design. With fuzzy logic, the imprecision of data can be dealt with in a similar way to how humans do it. Artificial neural networks are deemed to some extent to model the human brain, and simulate its functions in the form of parallel information processing. They are considered important components of Artificial Intelligence (Al). With neural networks, it is possible to learn from examples, or more precisely to learn from input-output data samples. The combination of the neural and fuzzy approach proved to be a powerful combination for dealing with qualitative data. The problem of automated knowledge modeling is efficiently solved by employment of machine learning techniques. Here, the expertise of prof. dr. Ozer Ciftcioglu in the field of soft computing was crucial for tool development. By combining knowledge from two different disciplines a unique tool could be developed that would enable intelligent modeling of soft data needed for support of the building design process. In this respect, this research is a starting point in that direction. It is multidisciplinary and on the cutting edge between the field of Architecture and the field of Artificial Intelligence. From the architectural viewpoint, the perception of space is considered through relationship between a human being and a built environment. Techniques from the field of Artificial Intelligence are employed to model that relationship. Such an efficient combination of two disciplines makes it possible to extend our knowledge boundaries in the field of architecture and improve design quality. With additional techniques, meta know/edge, or in other words "knowledge about knowledge", can be created. Such techniques involve sensitivity analysis, which determines the amount of dependency of the output of a model (comfort and public safety) on the information fed into the model (input). Another technique is functional relationship modeling between aspects, which is derivation of dependency of a design parameter as a function of user's perceptions. With this technique, it is possible to determine functional relationships between dependent and independent variables. This thesis is a contribution to better understanding of users' perception of underground space, through the prism of public safety and comfort, which was achieved by means of intelligent knowledge modeling. In this respect, this thesis demonstrated an application of ICT (Information and Communication Technology) as a partner in the building design process by employing advanced modeling techniques. The method explained throughout this work is very generic and is possible to apply to not only different areas of architectural design, but also to other domains that involve qualitative data.

summary To summarize former experiences of design seminars of the past years, the paper describes how new thinking and development structures within a design process, in conjunction with digital design media, requires new approaches to the design process itself. Also required are new solutions in adequate, three-dimensional, haptic presentation methods (model making), in order to secure the physical control of the computer-generated data structures. Points of origin have been several student projects whose conception was based on the idea of the contradiction of a modern architectural approach with its inclination to industrialized parts and series. The promise of the computer based design and manufacturing process seemed to allow the realization of almost every imaginable architectural shape for the same costs as those in regular planning and manufacturing processes. The different projects explored both static modeling methods and dynamic computer- driven development and presentation techniques. The latest project touches the field of an algorithm-based design process. Finally a possible process chain from early design stage into a three-dimensional, physical model is described. Considering the resources and financial budgets at universities, the development of an efficient manufacturing process with effective interfaces will summarize the method and finalize the study process.

title Computer Aided Dimensional Control in Building Construction
source Eindhoven University of Technology
summary Dimensional control in the building industry can be defined as the operational techniques and activities that are necessary, during the construction process of a building, for the assurance of the defined dimension quality of a building (Hoof, 1986). Efficient and precise dimensional control of buildings under construction is becoming ever more important because of changes in the construction industry. More prefabricated components are used; more regulations appear; newly designed buildings have more complex shapes, and building construction is speeding up. To ensure the predefined dimensional quality, a plan of dimensional control must be designed, on the basis of building drawings and specifications delivered by architects, before the building is constructed. The dimensional control plan must provide site personnel with adequate information on, among others, setting out and assembling building components, which can often be done by means of Total Stations. The essence of designing a dimensional control plan is to find out which points should be used as positioning points, which points should be set out in advance or controlled afterwards, and not to forget why. In an effort to contribute to the improvement of the dimensional control of on-site construction projects, this research tries to capture the knowledge required to design an adequate dimensional control plan and make that knowledge more generally available, and build a digital connection between CAD systems and Total Stations, focusing on prefabricated concrete building structural elements. The instrument developed in this research for capturing of essential dimensional control information and knowledge makes use of Product Data Technology (PDT) and Knowledge Technology (KT). The chosen solution supports the stochastic analysis of optimal positioning points taking account of various sorts of deviations and their mutual relationships. The resulting information model has been written in a standardized information modelling language called UML (Unified Modelling Language). The model has been implemented in a Dimensional Control System (DCS) and applied in the “La Tour” construction project in Apeldoorn, the Netherlands. The DCS provides a digital way to bridge the floor plan design with dimensional control, predict dimensional deviation limits and output the data needed for a Total Station. The case study of “La Tour” tests the UML model and prototype of the DCS. The results prove that direct positioning of objects (by putting reflectors on the objects and using a Total Station and by inputting coordinates extracted and calculated from the AutoCAD drawings) provides higher speed, accuracy and reliability. It also shows a way to (pre)position free form objects in 3D where traditional methods cannot. In conclusion: (1) it seems to be justified to expect that the application of the DCS will contribute to increased confidence in dimensional control and the reduction of costs of failure, which potentially could support the increased use of cheaper construction methods, and will also contribute to the improvement of building design and construction process. (2) the scientific contribution of this research is a first step towards providing dimensional quality in a construction process covered by stochastic dimensional uncertainty, even for positioning of free form objects.

summary The project IDEA+ aims to develop an “Integrated Design Environment for Architecture”. Its goal is providing a tool for the designer-architect that can be of assistance in the early-design phases. It should provide the possibility to perform tests (like heat or cost calculations) and simple simulations in the different (early) design phases, without the need for a fully detailed design or remodeling in a different application. The test for daylighting is already in development (Geebelen, to be published). The conceptual foundation for this design environment has been laid out in a scheme in which different design phases and scales are defined, together with appropriate tests at the different levels (Neuckermans, 1992). It is a translation of the “designerly” way of thinking of the architect (Cross, 1982). This conceptual model has been translated into a “Core Object Model” (Hendricx, 2000), which defines a structured object model to describe the necessary building model. These developments form the theoretical basis for the implementation of IDEA+ (both the data structure & prototype software), which is currently in progress. The research project addresses some issues, which are at the forefront of the architect’s interest while designing with CAAD. These are treated from the point of view of a practicing architect.

summary The number of different designers with different competencies collaborating in a building project is today conspicuous. An undesired consequence is the possible rise of conflicts between decisions taken independently by more than one specialist on the same building object. The early detection of such conflicts is then one of the most important features in collaborative design. Moreover, of great interest would be the possibility not only of automatic detection but also of solution proposal of at least the most manageable of those conflicts. In this perspective smart models of building components could be very useful. This is possible giving the building elements, represented as objects, the specific intelligence. A simple example of this possibility is given in this paper. In a precedent work we proposed a way of managing elementary spatial conflicts between building components tending to occupy the same spaces. The automatic detection derived from the previous declaration of two levels of constraints (soft constraint and hard constraints) in such way that a violation of them could be immediately signaled to the actor wanting to take the decision triggering the conflict. In this paper the topic is the consequences of the rise of a spatial conflict (occupation of the same space) between a column of a spatial frame of columns and beams, and another building object of any sort subject to a soft or hard constraint. The procedure identifies the minimum displacement of the two objects, propagates the column displacement to the other structural elements connected to it and checks the feasibility of the new configuration of the structural schema both with regard to the possible rise of new conflicts and with the compliance to previous structural criteria.

summary Heat flows (gains or losses) in a building are affected by solar radiation, internal gains and temperature differences. A prototype of a tool that evaluates solar radiation on building envelopes has been developed as an applet to run on the Internet. This tool analyses the relationship of the solar position with the surfaces of complex envelopes by evaluating the potential amount of direct solar radiation that each surface section receives as a function of the angle of each surface with the sun for specific days and latitudes. A fitness function rates the overall performance of the proposed building envelope at specific hours or whole days, permitting to compare alternatives. Because of its characteristics, this tool is a Very Simple Design tool that works interactively with the user during the design process helping to design solar responsive building envelopes.

summary As building projects become increasingly more complex, the number of project participants increases as does their spatial distribution. An effective decentralised work process and co-operation is of increasing importance. The global computer network, the internet, has great potential and recent times have seen the development of a variety of techniques in this field. The project proposal described here is based upon this approach and also takes it a step further. A specific analysis of the subject and the subsequent identification of potential approaches formed the basis for an architectural application that brings the architect in contact with other project participants using the internet as a powerful yet simple and easy to use medium. The project is currently (2002) undergoing practice tests and academic investigation and is installed on a freely-accessible server.

title Architectural Content System - ACS Internet Based Support for Architectural Planning Proceses
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 121-123
summary As building projects become increasingly more complex, the number of project participants increases as does their spatial distribution. An effective decentralised work process and co-operation is of increasing importance. The global computer network, the internet, has great potential and recent times have seen the development of a variety of techniques in this field. The project proposal described here is based upon this approach and also takes it a step further. A specific analysis of the subject and the subsequent identification of potential approaches formed the basis for an architectural application that brings the architect in contact with other project participants using the internet as a powerful yet simple and easy to use medium.

title A Parametric Strategy for Freeform Glass Structures Using Quadrilateral Planar Facets
doi https://doi.org/10.52842/conf.acadia.2002.303
source Thresholds - Design, Research, Education and Practice, in the Space Between the Physical and the Virtual [Proceedings of the 2002 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 1-880250-11-X] Pomona (California) 24-27 October 2002, pp. 303-321
summary The design and construction of freeform glass roofing structures is generally accomplished through theuse of either planar triangular glass facets or curved (formed) glass panes. This paper describesongoing research on the constructability of such structures using planar quadrilateral glass facets for theJerusalem Museum of Tolerance project by Gehry Partners, in collaboration with Schlaich Bergermann& Partners, engineers. The challenge here lies not only in the development of a geometric strategy forgenerating quadrilateral planar facet solutions, but also in the fact that said solutions must closely matchthe designs created initially in physical model form by the architects.We describe a simple but robust geometric method for achieving the structure by incorporating thenecessary geometric principles into a computational parametric framework using the CATIA Version 5system. This generative system consists of a hierarchical set of geometric ‘control elements’, that drivethe design toward constructible configurations. Optimization techniques for approximating the generatedstructural shape to the original created by the designers are also described. The paper presents theunderlying geometric principles to the strategy and the resulting computational approach.

title El ciclo, la línea y la trama. Las formas de aproximación a una educación en perpetua reforma [The cycle, the line and the grid. Ways to approach towards a progressive education.]
source SIGraDi 2002 - [Proceedings of the 6th Iberoamerican Congress of Digital Graphics] Caracas (Venezuela) 27-29 november 2002, pp. 47-50
summary The present situation of the educational procedures in Latin American countries are under a critical process of paradigmatic changes as a by product of the last connection with the industrial world and the first one of the “information society”. The design disciplines has been affected by this situation and started to be the main challenge for architects and designers in order to understand the potentialities of the new technologies avoiding to be used as simple “cliches”. Regarding digital technologies, the graduated and post graduated strategy for the new courses should be organized as flexible and open systems avoiding the “clip art” environment and the obsolete models of education. The “digital culture” combined with extensive procedures of “information technology” has defined an overwhelming expansion of “virtual services” (intangibles) in opposition of the “world of objects” (tangibles). Therefore we have been organized a new “digitaldesign”course at post graduated level comprising five careers (Architecture, Industrial, Graphic, Textil and Garment, and Imageand Sound Design) of our Faculty.

title Visual modeling and simulation for construction operations
source Automation in Construction 11 (1) (2002) pp. 47-57
summary Simulation practitioners in construction often experience difficulties in developing simulation models, i.e., tediousness and error-proneness. The visual environment presented in this paper gives users user-friendly support throughout the entire simulation development process, with the provision of a visual modeling interface, easy-to-use icon animation, and dynamic statistics. Under the visual modeling interface, modeling construction operations is completed through editing activity-based graphics as the standard graphic editing tools do, and no programming is required. An easy-to-use animation can facilitate communication between the simulation model and users, and assist users in verification and validation of the simulation model. Instead of creating 3-D images with adequate skills and much time, this animation takes the graphic simulation model as the background images and the pre-created 2-D iconic images as moving objects, in order that the preparing for animation is simple.

title Natural Forms As Virtual Architectures
doi https://doi.org/10.52842/conf.ecaade.2002.382
source Connecting the Real and the Virtual - design e-ducation [20th eCAADe Conference Proceedings / ISBN 0-9541183-0-8] Warsaw (Poland) 18-20 September 2002, pp. 382-385
summary The structures in nature are great lessons for human study. Having been in development for several billion years, only the most successful structural forms have survived. The resourcefulness of material use, the underlying structural systems and the profound capacity to respond to a variety of climatic and environmental forces make natural form tremendous exemplars to human architectures. The wholeness of natural form indicates that the form and forces are always in some sense of equilibrium. In most of natural forms, the quality of equilibrium may be difficult to recognize. However, seashells are one of the natural forms whose functions are simple enough to be approximated by a simple mathematical relationship. The focus of this study was to understand the seashell form as applicable to human architectures. The digital method is a language to create and simulate seashell forms. This paper suggesting a variety of possible architectural forms derived from a seashell.
