title	Visual-Physical Grammars
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper introduces new visual-physical design grammars for the design and manufacture of building assembly systems that provide visually rich, culturally resonant design variations for housing. The building systems are intended to be tailored for particular cultures and communities by incorporating vernacular, decorative design into the assembly design. Two complementary areas of computational design research are brought together in this work: shape grammars and digital fabrication. The visual or graphic aspects of the research are explored through shape grammars. The physical design and manufacturing aspects are explored through advanced digital design and fabrication technologies and, in particular, build on recent work on mono-material assemblies with interlocking components that can be fabricated with CNC machines and assembled easily by hand on-site (Sass, 2007). This paper describes the initial, proof-of-concept stage of this work: the development of an automated, visual-physical grammar for an assembly system based on a vernacular language of Greek meander designs. A shape grammar for the two-dimensional Greek meander language (Knight, 1986) was translated into a three-dimensional assembly system. The components of the system are uniquely designed, concrete “meander bricks” (Figure 1). The components have integrated alignment features so that they can be easily fitted and locked together manually without binding materials. Components interlock horizontally to form courses, and courses interlock vertically in different ways to produce a visual variety of meander walls. The assembly components were prototyped at desktop scale with a layered manufacturing machine to test their appearance after assembly and their potential for design variations (Figure 2). Components were then evaluated as full-scale concrete objects for satisfaction of physical constraints related to concrete forming and component strength. The automated grammar (computer program) for this system generates assembly design variations with complete CAD/CAM data for fabrication of components formed from layered, CNC cut molds. Using the grammar, a full-scale mockup of a corner wall section was constructed to assess the structural, material, and aesthetic feasibility of the system, as well as ease of assembly. The results of this study demonstrate clearly the potentials for embedding visual properties in structural systems. They provide the foundations for further work on assembly systems for complete houses and other small-scale structures, and grammars to generate them. In the long-term, this research will lead to new solutions for economical, easily manufactured housing which is especially critical in developing countries and for post-disaster environments. These new housing solutions will not only provide shelter but will also support important cultural values through the integration of familiar visual design features. The use of inexpensive, portable digital design and fabrication technologies will allow local communities to be active, cooperative participants in the design and construction of their homes. Beyond the specific context of housing, visual-physical grammars have the potential to positively impact design and manufacture of designed artifacts at many scales, and in many domains, particularly for artifacts where visual aesthetics need to be considered jointly with physical or material requirements and design customization or variation is important.

title	Computational Morphogenesis: Integral Form Generation and Materialization Processes
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 725-744
summary	Natural morphogenesis, the process of evolutionary development and growth, derives polymorphic systems that obtain their complex form, organisation and versatility from the interaction of system intrinsic material capacities and external environmental influences and forces. One striking aspect of natural morphogenesis is that formation and materialisation processes are always inherently and inseparably related. In stark contrast to these integral development processes of material form, architecture as a material practice is mainly based on design approaches that are characterised by a hierarchical relationship that prioritises the definition and generation of form over its subsequent materialisation. This paper will present an alternative approach to design that entails unfolding morphological complexity and performative capacity without differentiating between form generation and materialisation processes. Based on an understanding of material systems not as derivatives of standardized building systems and elements but rather as generative drivers in the design process this approach seeks to develop and employ computational techniques and digital fabrication technologies to unfold innate material capacity and specific latent gestalt. Extending the concept of material systems by embedding their material characteristics, geometric behaviour, manufacturing constraints and assembly logics within integral computational models promotes an understanding of form, material and structure not as separate elements, but rather as complex interrelations in polymorphic systems resulting from the response to varied input and environmental influences and derived through the logics and constraints of advanced manufacturing processes. These processes will be explained along 8 research projects.

title	Architecture and the Culture of Contingency
doi	https://doi.org/10.52842/conf.acadia.2007.025
source	Expanding Bodies: Art • Cities• Environment [Proceedings of the 27th Annual Conference of the Association for Computer Aided Design in Architecture / ISBN 978-0-9780978-6-8] Halifax (Nova Scotia) 1-7 October 2007, 25-31
summary	A culture is a set of behaviours, attitudes and values that are shared, sustained and transformed by an identifi able community. Currently, we are bound up in a culture of consumerism, and of terror; there are also retro cultures and utopian cultures. What’s happening now that’s interesting is that many, if not all of these diff erent tendencies, tastes and persuasions are being re-aligned, interconnected and hybridised by a vast global community of online users, who are transdisciplinary in their approach to knowledge and experience, instinctively interactive with systems and situations, playful, transgressive and enormously curious. This living culture makes it up as it goes along. No longer do the institu- tions of state, church or science call the tune. Nor can any architectural schema contain it. This is a culture of inclusion and of self-creation. Culture no longer defi nes us with its rules of aesthetics, style, etiquette, normalcy or privilege. We defi ne it; we of the global community that maps out the world not with territorial boundaries, or built environments, but with open-ended networks. This is a bottom-up culture—non-linear, bifurcating, immersive, and profoundly human. Who needs archi- tecture? Any structural interface will do. Ours can be described as a contingent culture. It’s about chance and change, in the world, in the environment, in oneself. It’s a contingent world we live in, unpredictable, unreliable, uncertain and indeterministic. Culture fi ghts back, fi ghts like with like. The Contingent Culture takes on the contingency of life with its own strategies of risk, chance, and play. It is essentially syncretic. People re-invent themselves, create new relationships, new orders of time and space. Along the way, they create, as well as accommodate, the future. This culture is completely open-ended, evolving and transforming at a fast rate—just as we are, at this stage of our evolution, and just as we want it to be. Human nature, unconstrained, is essentially syncretic too.

title	Teaching Digital Design Exploration: Form Follows
source	International Journal of Architectural Computing vol. 5 - no. 4, pp. 685-702
summary	This paper presents some challenges of teaching computational geometry to architectural students, and proposes a multi-level pedagogical scheme introducing associative geometry and parametric modeling/design into architectural design education. It reports on two pedagogical experiences: one held in the context of a spatial geometry course in the first year of education; and another one, in a digital design studio with third-year architectural students. More specifically, it discusses the impact on design exploration of a library of interactive referents models introduced into the architectural studio. Situated in the 'performance' paradigm of digital design methods, they allow for design object explorations based on modification of architecturally meaningful features (structural, environmental, functional, etc.). The form of a design object can thus 'follow' function, structure, or even sustainability. The digital methods and the design knowledge transferred by the interactive models, together with their visual nature, are found to amplify the processes of 'seeing-as' and the 'reflective conversation with the situation' considered essential for creative design.

title	Adaptation as a Framework for Reconsidering High-Performance Residential Design: A Case Study
doi	https://doi.org/10.52842/conf.acadia.2013.109
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 109-118
summary	This paper outlines an approach to adaptive residential design explored through recent research and an executed prototype, the North House project (2007-2009), undertaken through an interdisciplinary collaboration of researchers and students from the University of Waterloo, Ryerson University and Simon Fraser University in concert with professional and industry partners. This project aimed to develop a framework for the delivery of adaptive detached residential buildings capable of net-zero energy performance in the temperate climate zone, or the near north. Within this project, the term “adaptive” is developed across several tracts of conceptualization and execution including site and climatically derived models for building material composition and envelope ratios, environmentally-responsive kinetic envelope components, intelligent HVAC controls and interactive interface design aimed at producing co-evolutionary behaviors between building systems and inhabitants. A provisional definition of adaptive architecture is outlined to address this range of considerations that calls into question the stable image of domestic architecture and its relationship to energy and contemporary assumptions regarding sustainable design. This paper also outlines computational approaches to design optimization, distributed building systems integration and the human-controls interfaces applicable to the home’s ecology of physical and information technologies.

title	Hybrid Art > Synthesized Architecture
source	SIGraDi 2008 - [Proceedings of the 12th Iberoamerican Congress of Digital Graphics] La Habana - Cuba 1-5 December 2008
summary	This paper investigates possible intersections between some contemporary artistic modalities and architectural practice. At first, it describes and discusses different uses of art in architectural history. Through the analyzes of Le Corbusier’s artistic and architectural practices, it observes the limits of looking at art as only ‘inspiration’ for architectural form and points to the necessity of surpassing this formal approach. More than bringing pictorial ‘inspiration’, art, as a experimental field, can change our architectural procedures and approaches - a much richer and powerful addition to the development of architecture. It discusses then, the confluence of architecture, information and communication technologies. Very commonly present in our contemporary life, not only on the making of architecture – computer drawings and modeling of extravagant buildings – nor in ‘automated rooms’ of the millionaire’s houses. Televisions, telephones and computers leave the walls of our houses “with as many holes as a Swiss cheese”, as Flusser has pointed. The architecture has historically manipulated the way people interact, but this interaction now has been greatly changed by new technologies. Since is inevitable to think the contemporary world without them, it is extreme urgent that architects start dealing with this whole universe in a creative way. Important changes in architecture occur after professionals start to research and experiment with different artistic medias, not limiting their visions to painting and sculpture. The main hypothesis of this paper is that the experiments with new media art can bring the field of architecture closer to information and communication technologies. This confluence can only take form when architects rise questions about technology based interaction and automation during their creative process, embodying these concepts into the architecture repertoire. An educational experience was conducted in 2007 at UFMG Architecture School, in Brazil, with the intention of this activity was to allow students to research creatively with both information technology and architecture. The students’ goal was to create site-specific interventions on the school building, using physical and digital devices. Finally, the paper contextualizes this experience with the discussion above exposed. Concluding with an exposition of the potentialities of some contemporary art modalities (specially the hybrid ones) in qualifying architectural practices.

summary	This paper describes the implementation of a technology-enhanced metacognitive strategy that seeks to improve the learning outcomes in beginners design studios. The implementation was based on the use of time-based rich-media tools that allowed the students to document and present the different stages of their design process. The results of the design assignment in the experimental group were compared with the results of the same assignment implemented without such a metacognitive strategy and this comparison has provided evidence about the potential benefits of the tested methods.

title	Simulation Software Development for Urban Landscape Possibility Analysis
doi	https://doi.org/10.52842/conf.caadria.2007.x.u9u
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	This research paper proposes a simulation software development for possibility analysis of urban landscape development project. Normally, analysis of land potentiality and feasibility study for investment are necessary pre-processed for supporting urban planning, developing and architectural designing. However, most available tools are usually tailor made for each process individually, causing difficulties in information interchange between each processes. In this research, we propose a policy making support system for urban planning project development providing several functions such as testing land use and its physical character which are important to urban expansion and architectural design based on impact analysis of urban comprehensive plan. The proposed integrated system consists of a topological analysis module, constraint checking module and geographical information processing module. First, Geographical information stored in 3D graphic file format is converted to object-oriented data model and stored in a database. With several constraint and regulations, the stored information is then checked in the landscape topological analysis module. In evaluation process, the developed software is tested with geographical information of Bangkok area under constraints and regulations of Building Control Act of Thailand. While controlling building properties, the software can model the buildings and generate urban physical character. The result is then checked by several urban landscape planning experts. Experimental result shows that proposed system provides flexibility in information interchanging with constraints and regulations updating without system reconfiguration. The system also provides internet accessing for public participation in the process of making urban comprehensive plan.

title	Detecting Inefficient Lighting Solutions: Step-by-Step Geographic information system (GIS) Technique
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 491-504
summary	Outdoor lighting is used to illuminate roadways, parking lots, yards, sidewalks, public meeting areas, signs, work sites, and buildings. It provides us with better visibility and a sense of security. When well designed and properly installed, outdoor lighting can be and is very useful in improving visibility and safety and a sense of security, while at the same time minimizing energy use and operating costs. But, because nobody thought at this, most street lights shine light not only on the nearby ground, where is needed, but also miles away and skywards. Thus a large fraction of the light is lost, at consumer expense and without his/her consent. In the other hand, shortage in street light may cause more crimes as well as accidents. Most of the wasted or short light comes from the poorly designed street lights. Billboards, decorative lights, poorly shielded security lights are part of the problem too, but the main culprit for the waste and ugly glow one sees above one's head at nights is from the streetlights. Thus, recent computer technology gives us tools to be employed for testing the quality of light. Geographic Information System (GIS) software could be utilized to achieve that mission through applying mapping technique. This technique could analyze digital photographs and define light polluted areas as well as bad lighted. This paper reveals that step by step technique, which employs hybrid technologies to solve such problem for better planning decisions.

title	Multi-touch - the future of design interaction
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 557-572.
summary	The next major revolution for design is to bring the natural user interaction into design activities. Graphical User Interfaces (GUI) brought a new approach that was more effective compared to their conventional predecessors. In recent years, Natural User Interfaces (NUI) have advanced user experiences and multi-touch and gesture technologies provide new opportunities for a variety of potential uses in design. Much attention has been paid to leverage in the design of interactive interfaces. The mouse input and desktop screen metaphors limit the information sharing for multiple users and also delayed the direct interaction for communication between each other. This paper proposes the innovative method by integrating game engine ‘Unity3D’ with multi-touch tangible interfaces. Unity3D provides a game development tool as part of its application package that has been designed to let users to focus on creating new games. However, it does not limit the usage of area to design additional game scenarios since the benefits of Unity3D is allowing users to build 3D environments with its customizable and easy to use editor, graphical pipelines to openGL (http://unity3d.com/, 2010 ). It creates Virtual Reality (VR) environments which can simulates places in the real world, as well as the virtual environments helping architects and designers to vividly represent their design concepts through 3D visualizations, and interactive media installations in a detailed multi-sensory experience. Stereoscopic displays advanced their spatial ability while solving issues to design e.g. urban spaces. The paper presents how a multi-touch tabletop can be used for these design collaboration and communication tasks. By using natural gestures, designers can now communicate and share their ideas by manipulating the same reference simultaneously using their own input simultaneously. Further studies showed that 3Dl forms are perceived and understood more readily through haptic and proprioceptive perception of tangible representations than through visual representation alone (Gillet et al, 2005). Based on the authors’ framework presented at the last CAADFutures, the benefits of integrating 3D visualization and tactile sensory can be illustrated in this platform (Chen and Wang, 2009), For instance, more than one designer can manipulate the 3D geometry objects on tabletop directly and can communicate successfully their ideas freely without having to waiting for the next person response. It made the work more effective which increases the overall efficiency. Designers can also collect the real-time data by any change they make instantly. The possibilities of Uniy3D make designing very flexible and fun, it is deeply engaging and expressive. Furthermore, the unity3D is revolutionizing the game development industry, its breakthrough development platform for creating highly interactive 3D content on the web (http://unity3d.com/ , 2010) or similar to the interface of modern multimedia devices such as the iPhone, therefore it allows the designers to work remotely in a collaborative way to integrate the design process by using the individual mobile devices while interacting design in a common platform. In design activities, people create an external representation of a domain, often of their own ideas and understanding. This platform helps learners to make their ideas concrete and explicit, and once externalized, subsequently they reflect upon their work how well it sits the real situation. The paper demonstrates how this tabletop innovatively replaces the typical desktop metaphor. In summary, the paper addresses two major issues through samples of collaborative design: firstly presenting aspects of learners’ interactions with physical objects, whereby tangible interfaces enables them constructing expressive representations passively (Marshall, 2007), while focussing on other tasks; and secondly showing how this novel design tool allows designers to actively create constructions that might not be possible with conventional media.

title	Generative Systems Based on Animation Tools: Structure and Form of Core Ideas in Architectural Design
doi	https://doi.org/10.52842/conf.caadria.2007.x.k1h
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	The goal of the research described in this paper is the formulation of a generative system for architectural design, where a structured core architectural idea is the input and alternatives to that idea are the output. Specifically we present a production pipeline of architectural / spatial configurations using the context of animation and time based design tools. Our model consists of “time” and space design constraints of boundaries / objects affecting a given architectural design, thus producing an alternative solution for every timeframe of the animation cycle. Initially the designer shapes an idea using animation software tools, where each tool is actually a constraint or a grammar rule defined informally by the user/designer. The influence of the tools can vary according to time, speed, location, configuration of the object and/or the constraint itself. In some of these animations the designer has the ability to sidestep partially the issue of emergence by providing specific key - frames for the solution to follow. The use of animation tools [shape driven curves, speed and time-line functions, parent child relationships] in the shape generation of our model empowers the user/designer to configure whole sets of shapes and designs interactively and without the need to define every solution independently. Simultaneously, a different, time-focused view of our model describes its use on designs that develop different configurations over time. Thus a duality of our model is established : the animated schema may be either a sum or a family of various designs or the animated time-line may represent a single design which changes over time. Finally the possibility of a structured graph representing each solution is discussed, where the designer can evaluate the merit of an individual solution in terms of conforming to the initial core idea or where alternative spatial configurations evolve in a different structure from the original design.

summary	Emergent design tools, with enhanced modeling and parametric manipulation capabilities, are encouraging the exploration of new geometric typologies in the field of architecture. Designers are not only finding more opportunities to work with geometries of higher complexities but are also becoming able to manipulate their designs with simple formulations. After a decade of familiarity with free form modeling tools, architects must now become more aware of the critical relationship between design and construction. When a design is performed without taking the constraints of construction into account the inefficient method of geometric post-rationalization becomes necessary. Thus, the knowledge of the rationale should be applied from the very beginning of the design processes, and digital models should be informed and controlled while being developed. This paper will present analytical strategies and methods for working with nonstandard geometries in a geometrically and parametrically controlled environment. Each method is supported with custom scripts which run in both parametric and non-parametric computer aided design (CAD) platforms. Each script and method is manipulated for the next project and the computational tools created build up a library of surface generation, manipulation, and subdivision tools. This library later becomes a source for office-wide use of surface manipulation.

title	The influence of Lighting on the Affective Qualities of a Virtual Theater

summary	In the development of 3D models of buildings, much time and effort is spent on enhancing lighting effects, to improve the perceived realism and quality of the models, and to create ambience. In an experimental setup, two versions of a 3D model of the Royal Carré Theater with different lighting conditions were presented to viewers, to assess the influence of lighting effects on their affective appraisals. A small group visited the real theater. The differences between the affective qualities of the models are smaller than expected, and participants seem to infer affective qualities and dimensions of an environment without paying attention to the specific lighting information. The affective qualities of the real theater show a correspondence to both versions.

title	Sketch-based Methods for Researching Building Layouts through the Semantic Fingerprint of Architecture
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 85-102.
summary	The paper focuses on the early stages of the design process where the architect needs assistance in finding reference projects and describes different aspects of a concept for retrieving previous design solutions with similar layout characteristics. Such references are typically used to see how others have solved a similar architectural problem or simply for inspiration. Current electronic search methods use textual information rather than graphical information. The configuration of space and the relations between rooms are hard to represent using keywords, in fact transforming these spatial configurations into verbally expressed typologies tends to result in unclear and often imprecise descriptions of architecture. Nowadays, modern IT-technologies lead to fundamental changes during the process of designing buildings. Digital representations of architecture require suitable approaches to the storage, indexing and management of information as well as adequate retrieval methods. Traditionally planning information is represented in the form of floor plans, elevations, sections and textual descriptions. State of the art digital representations include renderings, computer aided design (CAD) and semantic information like Building Information Modelling (BIM) including 2D and 3D file formats such as Industry Foundation Classes (IFC) (IAI, 2010). In the paper, we examine the development of IT-technologies in the area of case-based reasoning (Richter et al., 2007) to provide a sketch-based submission and retrieval system for publishing and researching building layouts including their manipulation and subsequent use. The user interface focuses on specifying space and their relations by drawing them. This query style supports the spatial thinking approach that architects use, who often have a visual representation in mind without being able to provide an accurate description of the spatial configuration. The semantic fingerprint proposed by (Langenhan, 2008) is a description and query language for creating an index of floor plans to store meta-data about architecture, which can be used as signature for retrieving reference projects. The functional spaces, such as living room or kitchen and the relation among on another, are used to create a fingerprint. Furthermore, we propose a visual sketch-based interface (Weber et al., 2010) based on the Touch&Write paradigm (Liwicki et al., 2010) for the submission and the retrieval phase. During the submission process the architect is sketching the space-boundaries, space relations and functional coherence's. Using state of the art document analysis techniques, the architects are supported offering an automatic detection of room boundaries and their physical relations. During the retrieval the application will interpret the sketches of the architect and find reference projects based on a similarity based search utilizing the semantic fingerprint. By recommending reference projects, architects will be able to reuse collective experience which match the current requirements. The way of performing a search using a sketch as a query is a new way of thinking and working. The retrieval of 3D models based on a sketched shape are already realized in several domains. We already propose a step further, using the semantics of a spatial configuration. Observing the design process of buildings reveals that the initial design phase serves as the foundation for the quality of the later outcome. The sketch-based approach to access valuable information using the semantic fingerprint enables the user to digitally capture knowledge about architecture, to recover and reuse it in common-sense. Furthermore, automatically analysed fingerprints can put forward both commonly used as well as best practice projects. It will be possible to rate architecture according to the fingerprint of a building.

summary	In virtual workplace, two-dimensional system with desktop metaphor can provide only limited functions and interactions. It is indispensable to create a framework that can change traditional computer generated 3D model into interactive virtual architecture exploited by end users. However, such framework cannot be established without fundamental understanding of the new virtual architecture. The aim of this research emphasizes on how to design a virtual working place supporting actual office activities to extend the boundary of the conventional office through ‘Digital Space Lab’ case study. To achieve our goals, potential usability of virtual architecture is investigated. The next step is to design the virtual working place. After that, a set of scenarios indicating how the end users will utilize our interactive workplace is demonstrated. Eventually, the result serves as basis knowledge to construct a usability framework for the novel virtual architecture.

title	Applying generative modeling procedure to explore architectural forms
source	Em‘body’ing Virtual Architecture: The Third International Conference of the Arab Society for Computer Aided Architectural Design (ASCAAD 2007), 28-30 November 2007, Alexandria, Egypt, pp. 697-712
summary	Computer generated 3D forms using generative procedures have matured in the last decade and now considered as a tangible approach for realizing architectural design ideas. As fascinating as the approach might be, it is still lacking actual application in the early architectural design process. There are many reasons for this, among them: it has many implications over the architectural design process mainly the practicality of design during the conceptual design stage; it is cumbersome to develop construction drawings for complex architectural forms; and the necessity for producing conceptual designs quickly in less time as design requirements and decisions are constantly being changed. This paper initially reports on a practical development of a computer program which generates architectural massing designs based on integrating forms generation technique in a design scheme. The influence for this development was inspired by Spirolaterals technique used in generating complex 3D architectural forms that are based on parametric shape configuration. The development has three goals: to review the principles for constructing generative forms in the conceptual design stage using simple CAD tools, to assist in the production of design schemes based on a few basic shapes and rules, and to explore 3D forms finding and generation without the need to write a complicated computer program that are difficult to produce by hand. The development resulted in generating an interesting number of 3D compositions. The author applied this technique to experiment during the production of a design scheme. The paper hence describes the current development of ArchiGen tool to produces generative 3D forms utilizing ArchiCAD © GDL programming language. The tool is embedded within ArchiCAD for generating 3D shapes. One of the main features of this implementation is that users are able to sketch 2D shapes and the tool will deform its three dimensional generation. Moreover, the user being able to abstract the architectural character from the resulting complex 3D shapes. This development extends current related work by allowing the designer to load shapes into ArchiGen which acts as vocabulary of shapes for a design scheme constraints. It is intended from this work to inspire future work focusing on using generative tools in the early conceptual design stages.

title	The Creation of Urban Form: A Normative Approach to Modelling
doi	https://doi.org/10.52842/conf.caadria.2007.x.t8k
source	CAADRIA 2007 [Proceedings of the 12th International Conference on Computer Aided Architectural Design Research in Asia] Nanjing (China) 19-21 April 2007
summary	The aim of this research project is to develop a methodological process that allows the designer to assemble and create various scenarios representing an urban environment through the utilization of economical computer based methods. During the last decade different techniques have been developed to address the needs of visualisation of urban areas many being based on photographic and photogrammetric systems. The demand for 3-D urban models continues to grow and although new technologies have undoubtedly reduced the time needed for the construction of a 3D model, there are still some remaining problems related to data quality and the level of the dimensional accuracy. On the basis that these problems are primarily related to software and hardware constraints and in conjunction with the fact that the richness and complexity of an urban space is difficult to represent in a 3D context, there is a growing interest in the modelling of the urban fabric which is not dependant on heavily capitalised technology for its data. The core principle of the current research project is summarised in the process of deploying a mechanism, which will allow the visualisation of urban form without loosing its quality and architectural characterisation. This technique suggests that a selection of various building types can be collected and described by their architectural elements, textures, scale and dimensions. From each group of buildings a library of fragmented architectural components can be then derived. The accomplishment of this methodology is the formulation of a 'grammar' comprised of a characteristic ‘syntax’ and its associated ‘vocabulary’. Therefore the expected outcome of this research is an approach that would allow the designer to create easily and quickly not only any desired building but additionally any imaginary cityscape.

title	Simulating Dynamic Forces in Design with Special Effects Tools
doi	https://doi.org/10.52842/conf.ecaade.2007.219
source	Predicting the Future [25th eCAADe Conference Proceedings / ISBN 978-0-9541183-6-5] Frankfurt am Main (Germany) 26-29 September 2007, pp. 219-226
summary	Special effects technology can facilitate dynamic sketching in the early stage of a design project without needing time-consuming effort. This form of sketching was tested in a design studio taught by the author. The study of dynamic materials and oceanfront site conditions set the stage at the beginning of a design process for a more comprehensive analysis later on. On the one hand, the risk of using special effects tools is that the visual look can seem convincing, but the apparent result is based upon an overly simplified set of assumptions. On the other hand, the use of such technology can be very stimulating to the design imagination without requiring complex analysis that may bog down the free flow of ideas. Once a greater commitment is made to a particular design proposal, more complete physical analysis and modeling can be undertaken to help avoid the risk of false first impressions. In the studio, cloth simulation was used to develop the design of tension membrane structures (tents) that retracted and unfurled in a series of complex movements. Fluid dynamics effects were used in the design and development of related boat dock facilities. A wind-tunnel simulation tool was used to explore the performance of the tension-membrane fabrics under varied wind loads. The visualization techniques were complemented by ¼ to ½ scale assembled components created by rapid prototyping. The use of an actual wind-tunnel further tested the prototypes in some cases. On the whole, quickly implemented special effects were the starting point for reacting to and developing some initial design concepts and served as the basis for more complete physical modeling of prototypes later on. Using animation as a design method is well established in other work (Hirschberg 06). Animation is also a helpful way to work out the step by step assembly of complex architectural form (Mark 95). The special effects tools permit a larger range of initial design alternatives to be initially considered that are subsequently narrowed down by physically based prototypes that are more predictive of real world performance.
