title	Understanding Pre-Construction Simulation Activities to Adapt Visualization in 4D CAD Collaborative Tools
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. 477-492.
summary	Increasing productivity and efficiency is an important issue in the AEC field. This area is mainly characterized by fragmentation, heterogeneous teams with low lifetimes and many uncertainties. 4D CAD is one of the greatest innovations in recent years. It consists in linking a 3D model of the building with the works planning in order to simulate the construction evolution over time. 4D CAD can fill several needs from design to project management through constructivity analysis and tasks planning (Tommelein 2003). The literature shows that several applications have been proposed to improve the 4D CAD use (Chau et al. 2004; Lu et al. 2007; Seok & al. 2009). In addition, studies have shown the real impact of 4D CAD use in construction projects (Staub-French & Khanzode 2007; Dawood & Sika 2007). More recently, Mahalingam et al. (2010) showed that the collaborative use of 4D CAD is particularly useful during the pre-construction phase for comparing the constructability of working methods, for visually identifying conflicts and clashes (overlaps), and as visual tool for practitioners to discuss and to plan project progress. So the advantage of the 4D CAD collaborative use is demonstrated. Moreover, several studies have been conducted both in the scientific community and in the industrial world to improve it (Zhou et al. 2009; Kang et al. 2007). But an important need that remains in collaborative 4D CAD use in construction projects is about the adaptation of visualization to the users business needs. Indeed, construction projects have very specific characteristics (fragmentation, variable team, different roles from one project to another). Moreover, in the AEC field several visualization techniques can represent the same concept and actors choose one or another of these techniques according to their specific needs related to the task they have to perform. For example, the tasks planning may be represented by a Gantt chart or by a PERT network and the building elements can be depicted with a 3D model or a 2D plan. The classical view (3D + Gantt) proposed to all practitioners in the available 4D tools seems therefore not suiting the needs of all. So, our research is based on the hypothesis that adapting the visualization to individual business needs could significantly improve the collaboration. This work relies on previous ones and aim to develop a method 1) to choose the best suited views for performed tasks and 2) to compose adapted multiple views for each actor, that we call ‚Äúbusiness views‚Äù. We propose a 4 steps-method to compose business views. The first step identifies the users‚Äô business needs, defining the individual practices performed by each actor, identifying his business tasks and his information needs. The second step identifies the visualization needs related to the identified business needs. For this purpose, the user‚Äôs interactions and visualization tasks are described. This enables choosing the most appropriate visualization techniques for each need (step 3). At this step, it is important to describe the visualization techniques and to be able to compare them. Therefore, we proposed a business view metamodel. The final step (step 4) selects the adapted views, defines the coordination mechanisms and the interaction principles in order to compose coordinated visualizations. A final step consists in a validation work to ensure that the composed views really match to the described business needs. This paper presents the latest version of the method and especially presents our latest works about its first and second steps. These include making more generic the business tasks description in order to be applicable within most of construction projects and enabling to make correspondence with visualization tasks.

title	Social Experiments in Design Technology
source	Computation: The New Realm of Architectural Design [27th eCAADe Conference] Istanbul (Turkey) 16-19 September 2009

summary	The delivery of a successful project demands high levels of collaboration across an expanded design team, which now includes consultants, fabricators and contractors as well as architects and engineers. The pace of development in design technology has been very rapid during the last few years and there are now many software products which offer high levels of sophistication. Most provide associative and parametric modelling strategies, which can be further enhanced and extended by the use of scripting languages. Designers are becoming tool-builders while fabricators are becoming digital craftsmen. With the advent of fast efficient drawing extraction the industry is at last making determined steps towards a model-driven process. However there is no integrated platform which supports the free exchange of ideas, combined with the evaluation of performance, experimentation with production techniques and the evolution of project-specific workflows. In education the design schools have been quick to recognise the potential of the new design technology. This has led to a rapid expansion in course curricula that now offer many new specialisations, most of which also need to be under-pinned by a good grounding in descriptive geometry, mathematics and physics. The architect as a generalist, who coordinates the work of specialists, is being challenged by an increasing breadth of technical studies that require more than just a superficial depth of understanding. In practice the gulf is widening even more rapidly. New graduates, who often have spectacular expertise in modelling and fluency in scripting languages, do not yet have the design and construction experience necessary to direct their efforts to best effect. On the other hand people running project teams do not have the technical background to understand the potential of the skills and resources that are available. Today there is no longer the continuity that used to derive from apprenticeship. As we experiment we find that tools based on new ideas and techniques can radically change workflow – but fear of the unknown can provoke resistance. So the problems we face in harnessing the new technology are as much social and cultural as they are technical. The presentation will focus on developing attitudes towards tool-building with the aim of integrating design, analysis and production. This is part of a continual and quite gradual process, which requires the ability to play interpretive roles that help to bring about cultural change. Examples will be shown from the work of the Specialist Modelling Group at Foster+Partners who now have tenyears experience in deploying design technology in an environment where research is intensely project driven.

summary	The Catoptric Surface research project explores methods of reflecting daylight through a building envelope to form an image-based pattern of light on the interior environment. This research investigates the generation of atmospheric effects from daylighting projected onto architectural surfaces within a built environment in an attempt to amplify or reduce spatial perception. The mapping of variable organizations of light onto existing or new surfaces creates a condition where the perception of space does not rely on form alone. This condition creates a visual effect of a formless atmosphere and affects the way people use the space. Often the desired quantity and quality of daylight varies due to factors such as physiological differences due to age or the types of tasks people perform (Lechner 2009). Yet the dominant mode of thought toward the use of daylighting tends to promote a homogeneous environment, in that the resulting lighting level is the same throughout a space. This research project questions the desire for uniform lighting levels in favor of variegated and heterogeneous conditions. The main objective of this research is the production of a unique facade system that is capable of dynamically redirecting daylight to key locations deep within a building. Mirrors in a vertical array are individually adjusted via stepper motors in order to reflect more or less intense daylight into the interior space according to sun position and an image-based map. The image-based approach provides a way to specifically target lighting conditions, atmospheric effects, and the perception of space.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
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. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.

source	T. Tidafi and T. Dorta (eds) Joining Languages, Cultures and Visions: CAADFutures 2009, PUM, 2009, pp. 288-300
summary	Computer-Aided Design (CAD) has become more and more part of the common architectural practice. Some designers have explored (in the past) different aspects, especially formal ones, allowed by these new information technologies. This paper’s goal is to explore the invention that would be specific to this new architectural practice. The hypothesis is to go back to the specificity of the image and to examine its evolution. This analysis will be done with reference to the « cycle of images » of the French philosopher Gilbert Simondon, described by means of stages and levels. This particular way of thinking will allow us, besides an overview of all those images in a genetic diagram, to reveal what can enable the passage from one level to another. We call this : “invention”.

summary	The present research is an exploratory study about medium-range 3D-scanning technologies for architectural applications. Its purpose was to gather information that will subside the future acquisition of a 3D-scanning equipment for the Laboratory for Automation and Prototyping for Architecture and Construction, LAPAC, at the University of Campinas (UNICAMP). In order to test some of these technologies, some experiments were carried out. Museum sculptures were digitized and the results were 3D-printed. Preliminary results show that accurate technologies are still very expensive, but there are some alternative, more accessible technologies, based on photogrammetry, which can lead to fairly good results.

title	Exploring Intended Implicate Solution

doi	https://doi.org/10.52842/conf.caadria.2009.567
summary	Design is an iterative exploration process that will invoke many fragmented information with continuous iteration. While fragmented, implicit information lay among these fragmented pieces has shown more potential to achieve some goals that we might skip during the decisionmaking. These potential design goals named implicit intended solution are the problem spaces we want to explore in this research. Therefore, the continuous thinking/operation process cross these fragmented design decision might show some insights for discovering implicit intended solutions. This is a two-fold problem, without exploration and its continuous iteration characteristics, these solutions might not even be found or possible found. Therefore, in this paper we have conducted a research based on visualizing these implicit intended solutions as well the exploration process for finding them.

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	Retrieving Lost Space With Tangible Augmented Reality
source	Proceedings of the 14th International Conference on Computer Aided Architectural Design Research in Asia / Yunlin (Taiwan) 22-25 April 2009, pp. 135-142
doi	https://doi.org/10.52842/conf.caadria.2009.135
summary	Tangible Augmented Reality can be an innovative way for designers to understand the spatial conception. Due to the high integration of tactile and vision, this realm allows users to gain a better understanding how to retrieve ‘lost space’ in an urban context. By using a variety of visualisation methods, such as wireframe and transparencies, hidden or other ways unperceivable (lost) space is made available. With the aid of Tangible Augmented Reality designers are subsequently able to evaluate the design context and its solution more holistically. This paper argues that the retrieval of lost space enhances the design communication.

summary	In-Between Architecture Computation describes the evolution of the Computational Design approach at the AedasR&D Computational Design and Research group founded in 2004 at Aedas architects in London. The approach has transformed itself from an academic inspired thinking about computing media to a more flexible model of design heuristics and search algorithms that finally start to produce new hybrid design workflows in the industry while also swimming against the industry trend of super-integration software. Only if computing is not exclusively defined through architectural design intent or purely computing logic, does computational design explore new design thinking.

title	Thermal Simulation In Residential Building Within Computer Aided Architectural Design: Integrated model
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 235-243
summary	Nowadays, the architectural profession is seeking a better energy saving in the design of buildings. The fear of energy shortage in the very near future, together with the rapid rise in energy prices, put pressure on researchers on this field to develop buildings with more efficient heating systems and energy systems. This work is concerned mainly with the development of a software program analyzing comfort in buildings integrated in CAD architectural systems. The problem of presenting the computer with information concerning the building itself has been overcome through integration of thermal analysis with the building capabilities of CAD system. Mainly, such experience concerns the rules for calculating heat loss and heat gain of buildings in Algeria, The program has been developed in order to demonstrate the importance of the innovation of the computer aided-architectural-design field (CAAD) in the technology of buildings such as the three dimensional modeling offering environmental thermal analysis. CAAD is an integrated architectural design system which can be used to carry out many tasks such as working drawings, perspectives and thermal studies, etc., all from the same data. Results are obtained in tabular form or in graphical output on the visual display. The principle of this program is that all input data should be readily available to the designer at the early stages of the design before the user starts to run the integrated model. Particular attention is given to the analysis of thermal aspects including solar radiation gains. Average monthly energy requirement predictions have been estimated depending on the building design aspect. So, this integrated model (CAAD and simulation comfort) is supposed to help architects to decide on the best options for improving the design of buildings. Some of these options may be included at the early design stages analysis. Indications may also be given on how to improve the design. The model stored on CAAD system provides a valuable data base for all sort analytical programs to be integrated into the system. The amount of time and expertise required to use complex analytical methods in architectural practice can be successfully overcome by integration with CAAD system.

summary	The demand for up-to-date information and design ‘tools’ to help architects design more sustainable buildings is rapidly expanding. This demand has led to use various ecological assessment tools as support tools for the design process. The absence of adequate tools, which contribute to early stages, as well as the additional costs of tardy modifications, has led us to propose an eco-design support tool. This tool is based on a methodology named “Eco-Model (EM) Method” that focuses on the ecological approaches of a building. This method proposes to consider environmental friendly solutions from the first sketches by proposing a number of micro-solutions, called here Eco-Model or “EM”. Subsequently, the study presents the first contour of software based on an EM approach. Thus, the various actors of the design team will be able to browse the useful information for their green projects and so collaborate to optimize the building design.

doi	https://doi.org/10.52842/conf.caadria.2009.277
summary	Prototype manufacturing as an educational tool has been very successful at the college level in architecture and engineering design. This paper discusses an innovative inquiry-based learning approach rather than the problem-based learning models commonly utilized by other similar programs. For example, several research-funded technology projects (e.g., Cappelleri et al. 2007) look at involving students in problembased learning exercises (e.g., building robots); however, these exercises (while providing valuable experiences) have predetermined outcomes ingrained by the teachers, the project structure, and the components used to construct the devices. Therefore, inquisitive and creative problem solving is limited to the “kit-of-parts” in their approach to solving the problem. The inquiry-based CADCAM pedagogy model is more concerned with the process of solving a problem through the vehicle of prototyping than with the specificity of the design project itself. This approach has great potential. First, the need to solve the problem drives learning on multiple levels, integrating interdisciplinary ideas into the problem and solution. Second, the problem interlocks disciplines through inquiry knowledge building in team exercises. Finally, it encourages diversity and flexibility by allowing students to look at problems from multiples perspectives and points of view.

title	Crafting New Artefacts

doi	https://doi.org/10.52842/conf.caadria.2009.205
summary	The craft of complex artefacts, questioning technological changes and reflecting social and cultural transformation used to be a common attitude in traditional artisans of the pre industrialized society. Traditional craftsman developed special knowledge and skills, implementing their own tools and techniques. After the industrial revolution, the main focus shifted to mass production, and the personalization of artefacts became labour intensive and more expensive. Simultaneously, with technical specialization and the fragmentation of knowledge, the designer’s, builder’s and manufacturer’s approach became more segregated. Currently, information technologies offer new opportunities to the craft of complex objects. The integration of digital process from conception to fabrication, can transform this situation, and as a result personalization is more affordable. Nevertheless, the introduction of these new techniques or tools is lacking a poetic synthesis for the use of technology, and the social and cultural implications that may result of this use. A competition for a public installation was an opportunity to use digital tools to conceive, manufacture and construct a complex structure with a small budget that would be impossible to attain using only traditional tools. At the same time, this project - genetic landscape- could be seen as a metaphor, alluding to the technological interference on the process of creating a new life, or a second nature.

title	Wearable Personal Assistants for the Management of Historical Centers
source	International Journal of Architectural Computing vol. 7 - no. 1, 139-156
summary	One of the main tasks facing the manager of a historical centre is to avoid degradation while retaining the historical value. For this reason, any intervention which takes place on the environment, should be carefully managed. Only when performing a proper diagnosis of the environment and its reality is possible to follow a high quality intervention. The integration of new information technologies has been crucial to the improvement of these processes providing new tools. Within the project called RASMAP, we have designed and implemented a mobile augmented reality platform based on a service oriented architecture. This project introduces the concept of Wearable Personal Assistant (WPA). WPA in the RASMAP platform represents an innovative wearable tool, which provides support to professionals in their daily activities (mechanical engineer, safety responsible person, diagnosis expert, etc.). This tool is based on augmented reality technologies, mobile devices and communication infrastructures. The development of the platform for the WPAs implies addressing several technological challenges: a) to overcome the limitations inherent in the mobile devices: speed, capacity of memory, capacity of storage, graphical features and others, b) to obtain tracking systems that they do not need to alter or to adapt the environment, c) to optimize for the transmission and reproduction of multimedia contents through wireless networks on mobile devices. In this article, we describe the RASMAP platform, as a basis for the development of WPA and the extension of its use for the management of historical centres. The quality and usefulness of the scientific-technological results provided by the WPA have been validated developing a demonstrator for the diagnosis of the conservation status of the historical centre of a small town in the Basque Country. The advantages to be gained by using WPA in the proposed scenario are among others: more efficient processes, improved communication between users, and local and distributed multimedia content records.

title	Digital Modeling in Traditional Architecture Learning: the method and benefits
source	Digitizing Architecture: Formalization and Content [4th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2009) / ISBN 978-99901-06-77-0], Manama (Kingdom of Bahrain), 11-12 May 2009, pp. 153-162
summary	This paper looks at learning from The traditional architecture with the aid of digital 3D modelling aimed to support the process of architectural design in a studio environment where designs can be tested without the practicalities of the real world. The process of architectural design in itself is an unknown phenomenon for new students of architecture, so they look to digital 3D modelling to help them in understanding the vernacular or traditional architecture vocabulary. The question therefore, is how can digital 3D modelling underpin a student’s own design philosophy and experience? Also is there any place for the older students, in making this process more productive? The digital 3D modelling of a sample traditional house in historical Jeddah has allowed for a study and learning from of traditional architecture. Observing students over one semester, it was apparent that a more open critical ability developed in understanding the vernacular or traditional architecture vocabulary. Based on feedback from students, we have developed guidelines and recommendations for teaching traditional architecture with the help of 3D digital modelling technologies. We believe we have improved the quality of the Department's small-group teaching and encouraged students to treat communication and 3D modelling skills as valuable. Our results show techniques of creating 3D digital modelling can be very helpful in teaching the vocabulary of our traditional architecture. Digital 3D modelling in this way seems an ideal tool in traditional architectural education which is presently neglected.

summary	This paper will describe the design and evolution of an open source Ruby plug-in for Google SketchUp that allows geometry with UVW mapping to be exported for integration within a popular first person computer game (UT2004 and UT3 by Epic games). It will illustrate the advantages of this simplified workflow by discussing the range of complex geometries, lighting, atmospherics and interactive opportunities arrived at by students at the University of New South Wales School of Architecture. The paper will use examples of work generated using this new workflow to critically reflect on previous efforts in the use of computer games technology for architectural representation. An argument is made that while the instability that characterized computer game modding in the recent past can be productively embodied by experienced designers in architectural design projects instability itself and the complexities it engenders does not facilitate computer game modding by less experienced designers. The formal complexity and richness of experience presented by less experienced student’s speaks to the advantages of using a simplified workflow while highlighting strengths and weaknesses in previous approaches.

summary	Reinforced concrete has been one of the essential materials for modern architecture for the last hundred years. Its use is entirely global, having been adopted by all cultures and styles since its invention in the late 19th century. Although its value is excellent due to its low cost, durability and adaptability, its environmental impact is significant, being, in fact, one of the most polluting industries in the world (Babor et al. 2009). This experimental project will research a more sustainable use of concrete, exploring a new form of reusable concrete formwork that will ideally reduce the CO2 footprint by removing wood waste in the casting process and replacing it with adaptable metal components. The modular part-based system for the concrete casting also attempts to simplify one of the current complexities for concrete construction, the Skilled-Labour shortage. (Yusoff et al. 2021). To mitigate this problem, the project also proposes using an Augmented Assembly logic for the casting parts to guide the ensemble and dismantle the formwork through an optimised algorithmic logic. The use of Augmented Reality as a replacement for traditional paper instructions will facilitate access to more workers to this construction art and potentially improve access to optimised use of concrete in developing communities with restricted building technological resources.

summary	Wood differs from most building materials in that it is a naturally grown biological tissue. Thus wood displays significant differentiation in its material makeup and structure as compared to most industrially produced, isotropic materials. Upon closer examination wood can be described as an anisotropic natural fiber system with different material characteristics and related behavior in different directions relative to the main grain orientation. Because of its differentiated internal capillary structure wood is also hygroscopic. It absorbs and releases moisture in exchange with the environment and these fluctuations cause differential dimensional changes. In architectural history the inherent heterogeneity of wood and the related more complex material characteristics have been mainly understood as a major deficiency by the related crafts, timber industry, engineers and architects alike. This paper will present an alternative design approach and associated computational design tools that aim at understanding wood’s differentiated material make up as its major capacity rather than a deficiency. Along two design experiments the related research on an integral computational design approach towards unfolding wood’s intrinsic material characteristics and performative capacity will be discussed. The first experiment explores the anisotropic characteristics of wood by exploiting the differential bending behavior in relation to the local induction of forces through which a specific overall morphology can be achieved. The second experiment focuses on the hygroscopic property of wood as the base for developing a surface structure that responds to changes in relative humidity with no need for any additional electronic or mechanical control.

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