title	A Computational Approach to the Reconstruction of Surface Geometry from Early Temple Superstructures
source	International Journal of Architectural Computing vol. 3 - no. 4, 471-486
summary	Recovering the control or implicit geometry underlying temple architecture requires bringing together fragments of evidence from field measurements, relating these to mathematical and geometric descriptions in canonical texts and proposing "best-fit" constructive models. While scholars in the field have traditionally used manual methods, the innovative application of niche computational techniques can help extend the study of artefact geometry. This paper demonstrates the application of a hybrid computational approach to the problem of recovering the surface geometry of early temple superstructures. The approach combines field measurements of temples, close-range architectural photogrammetry, rule-based generation and parametric modelling. The computing of surface geometry comprises a rule-based global model governing the overall form of the superstructure, several local models for individual motifs using photogrammetry and an intermediate geometry model that combines the two. To explain the technique and the different models, the paper examines an illustrative example of surface geometry reconstruction based on studies undertaken on a tenth century stone superstructure from western India. The example demonstrates that a combination of computational methods yields sophisticated models of the constructive geometry underlying temple form and that these digital artefacts can form the basis for in depth comparative analysis of temples, arising out of similar techniques, spread over geography, culture and time.

title	On Recovering the Surface Geometry of Temple Superstructures
source	CAADRIA 2005 [Proceedings of the 10th International Conference on Computer Aided Architectural Design Research in Asia / ISBN 89-7141-648-3] New Delhi (India) 28-30 April 2005, vol. 2, pp. 253-258

summary	The application of computational techniques to the analysis of heritage artifacts enables scholars to bring together diverse fragments of surviving evidence, construe “best-fit” strategies and unearth implicit or hidden relationships. This paper reports a hybrid approach for recovering the surface geometry of temples. The approach combines physical measurements, architectural photogrammetry and generative rules to create a parametric model of the surface. The computing of surface geometry is broken into three parts, a global model governing the overall form of the superstructure, local models governing the geometry of individual motifs and finally the global and local models are combined into a single geometry. In this paper, the technique for recovering surface geometry is applied to a tenth century stone superstructure: the temple of Ranakdevi at Wadhwan in Western India. The global model of the superstructure and the local model of one individual motif are presented.

title	Fabrication with Residual Wood through Scanning Optimization and Robotic Milling
source	Kontovourkis, O, Phocas, MC and Wurzer, G (eds.), Data-Driven Intelligence - Proceedings of the 42nd Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2024), Nicosia, 11-13 September 2024, Volume 1, pp. 25–34
doi	https://doi.org/10.52842/conf.ecaade.2024.1.025
summary	The project deals with the use of residual wood of tree stumps and roots through scanning, optimization and robotic milling. Wood logging residue makes up to 50 percent of the trees harvested biomass. (Hakkila and Parikka 2002). Among prevailing strategies is leaving residue on site, and recovering residue for bioenergy. (Perlack and others 2005). The project explores the third strategy, using parts of the logging residue for fabrication, which may reduce the overall amount of wood logging volume. Furthermore approach aims for applying residue in its natural form and taking advantage of specific local characteristics of wood (Desch and Dinwoodie 1996). The project applies the strategy on working with stump and roots of an oak tree. Due to considerations of scale, available milling technics and available resources, chosen goal of the approach is to create a functioning chair prototype. Among the problems of the approach is the complex shape of the residue, uneven quality of wood, varying humidity and contamination with soil. After cleaning and drying, the stump is scanned and a 3D model is created. The 3D model od a stump is confronted with a 3D modelled limits of the goal typology (height, width, length, sitting surface area and overal volume of a chair) and topological optimization algorithm is used to iteratively reach the desired geometry. Unlike in established topological optimization proces, which aims for a minimal volume, the project attempts to achieve required qualities with removing minimal amount of wood. Due to geometric complexity of both stump and goal object, milling with an 6axis industrial robotic arm and a rotary table was chosen as a fabrication method. The object was clamped to the board (then connected to a rotary table) in order to provide precise location and orientation in 3D space. The milling of the object was divided in two parts, with the seating area milled in higher detail. Overall process of working with a residual wood that has potential to be both effective and present aesthetic quality based on individual characteristics of wood. Further development can integrate a generative tool which would streamline the design and fabrication proces further.

title	From Bézier to NURBS: Integrating Material and Digital Techniques through a Plywood Shell
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 156-169

summary	The development of digital fabrication has reintroduced material processes with digital processes. There has been much discussion about the tool and the objects of the tool, but little discussion of the implication of the material process on the digital process. A brief historical review on the development of computer numerical control and the origins of the Bézier curve reveals an instrumental fact: computer numerical controlled tools necessitated advancements in computational surfaces which eventually led to NURBS (Non-Uniform Rational B-Splines) surfaces. In other words, the origins of NURBS surfaces resides in its relation to material processes, rather than many current approaches that develop free form surfaces and then force the tool onto the material without regard to the material properties. From this historical and mathematical review, this project develops toward more intelligent construction methods based on the integration of NURBS differential geometry paired with material qualities and processes. Specifically, a digital technique of developing conceptual NURBS geometry into piecewise surface patches are then flattened based on the material thickness and density. From these flattened patches, a material technique is developed to intelligently remove material to allow the rigid flat material to re-develop into physical surface patches. The goal of this research is to develop digital and material techniques toward intelligent construction based on the correspondence between digitally driven surface and digitally driven material processes. The application of this technique as a rational and flexible system is to support the dynamic response of form and material toward such performative aspects as structure, daylight, ventilation, and thermal properties.

title	The Generation of Superstructure Geometry in Latina Temples: A Hybrid Approach
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 483-488

summary	The Nâgara tradition of temple building created a rich corpus of Latina (single-spired) temples spread across Northern India between the fifth and thirteenth centuries. Computing methods offer a distinct methodology for reconstructing the genesis and evolution of geometry in this tradition over time. This paper reports a hybrid technique, comprising three distinct computations for recovering and explaining the geometry of temples. The application of the technique enables scholars to bring together fragments of evidence, construe “best-fit” strategies and unearth implicit or hidden relationships. The advantage of this approach is that changes in assumptions and testing of geometric alternatives can be easily simulated from multiple sources of information, such as texts, sacred diagrams and individual temples.

title	Responsiveness and Social Expression; Seeking Human Embodiment in Intelligent Façades
source	Smart Architecture: Integration of Digital and Building Technologies [Proceedings of the 2005 Annual Conference of the Association for Computer Aided Design In Architecture / ISBN 0-9772832-0-8] Savannah (Georgia) 13-16 October 2005, pp. 12-23
doi	https://doi.org/10.52842/conf.acadia.2005.012
summary	This paper is based on a comparative analysis of some twenty-six intelligent building facades and sixteen large media-facades from a socio-psychological perspective. It is not difficult to observe how deployment of computational technologies have engendered new possibilities for architectural production to which surface-centeredness lies at that heart of spatial production during design, fabrication and envelope automation processes. While surfaces play a critical role in contemporary social production (information display, communication and interaction), it is important to understand how the relationships between augmented building surfaces and its subjects unfold. We target double-skin automated facades as a distinct field within building-services and automation industry, and discuss how the developments within this area are over-occupied with seamless climate control and energy efficiency themes, resulting into socially inert mechanical membranes. Our thesis is that at the core of the development of automated façade lies the industrial automation attitude that renders the eventual product socially less engaging and machinic. We illustrate examples of interactive media-façades to demonstrate how architects and interaction designers have used similar technology to turn building surfaces into socially engaging architectural elements. We seek opportunities to extend performative aspects of otherwise function driven double-skin façades for public expression, informal social engagement and context embodiment. Towards the end of the paper, we propose a conceptual model as a possible method to address the emergent issues. Through this paper we intend to bring forth emergent concerns to designing building membrane where technology and performance are addressed through a broader cultural position, establishing a continual dialogue between the surface, function and its larger human context.

title	Integrating Digital and Building Technologies: Towards a New Architectural Composite
source	International Journal of Architectural Computing vol. 3 - no. 2, 181-190
summary	This paper presents an ongoing research project about the development of the materials and fabrication techniques for a fundamentally new class of architectural composite. This type of composite, which is a representative example of an even broader class of smart architectural material, has the potential to change the design and function of an architectural structure or living environment. As of today, this kind of composite does not exist. Once completed, this will be the first technology on its own. We believe this study will lay the fundamental groundwork for a new paradigm in surface engineering that may be of considerable significance in architecture, building and construction industry, and materials science.

title	Three-Dimensional Shape Generation of Low-Energy Architectural Solutions using Pareto Genetic Algorithms
source	Digital Design: The Quest for New Paradigms [23nd eCAADe Conference Proceedings / ISBN 0-9541183-3-2] Lisbon (Portugal) 21-24 September 2005, pp. 647-654
doi	https://doi.org/10.52842/conf.ecaade.2005.647
summary	This paper extends on a previous work on the application of a Generative Design System [GDS] to the evolution, in a computational environment, of three-dimensional architectural solutions that are energy-efficient and adapted to the climatic environment where they are located. The GDS combines a well-known building energy simulation software [DOE2.1E] with search procedures based on Genetic Algorithms and on Pareto optimization techniques, successfully allowing to tackle complex multi-objective problems. In the experiments described, architectural solutions based on a simplified layout were generated in response to two often-conflicting requirements: improving the use of daylighting in the space, while controlling the amount of energy loss through the building fabric. The choice of a cold climate like Chicago provided an adequate framework for studying the role of these opposing forces in architectural form generation. Analysis of results shows that building characteristics that originate successful solutions extend further than the building envelope. Issues of massing, aspect ratio, surface-to-volume ratio, orientation, and others, emerge from the analysis of solutions generated by the GDS, playing a significant role in dictating whether a given architectural form will prove adapted to its climatic and energy requirements. Results suggest that the questions raised by the exploration of form generation driven by environmental concerns are complex, deserving the pursuit of further experiments, in order to better understand the interaction of variables that the evolutionary process congregates.

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.

summary	In 1990, due to the traditional architecture design and construction method difficult to build the complicated and non-geometry free-form Fish Structure in Barcelona, architect Frank Gehry started learn from the field of aerospace to utilize CAD/CAM technology in design and manufacture process. He created the free-form fish model in CAD system and exported the digital CAD model data to CAM machine (RP and CNC) to fabricate the design components, and finally assembled on the site. Gehry pioneered in the new digital design process in using CAD/CAM technology or so-called digital fabrication. It becomes an important issue recently as the CAD/CAM technology progressively act as the new digital design media in architectural design and construction process (Ryder et al., 2002; Kolarevic, 2003). Furthermore, in the field of architecture professional, some commercial computer systems had been developed on purpose of standardizes the digital design process in using CAD/CAM fabrication such as Gehry Technologies formed by Gehry Partners; SmartGeometry Group in Europe and Objectile proposed by Bernard Cache. Researchers in the research field like Mark Burry, Larry Sass, Branko Kolarevic, Schodek and others are enthusiastic about the exploration of the role of CAD/CAM fabrication as new design media in design process (Burry, 2002; Schodek et al., 2005; Lee, 2005).

title	ICHTYOMORPH - Design and development of a fish-skin double façade system for freeform super tall buildings using Parametric Design Tools
source	SIGraDi 2005 - [Proceedings of the 9th Iberoamerican Congress of Digital Graphics] Lima - Peru 21-24 november 2005, vol. 1, pp. 144-149
summary	Parametric design implies a whole new paradigm of non standard design through the propagation of the difference, the repetition of variation. The ability to control variation and adaptation to local conditions allows more precise yet complex designs. This paper describes a research project designing double skin façade systems for tall buildings using a parametric approach. These designs are tested later through rapid prototyping techniques. This research aims its design towards an adjustable façade structure, articulated according to various complex geometrical conditions on the façade of a building. The skin is conceived as a light, flexible, reconfigurable composition responding to different criteria regarding the design, its environment or the program. It achieves this through different levels of control on different scales of the project, by embedding several layers of parametric features, which are nested one inside the other, in order to produce the overall rainscreen surface of the tower.

title	Design Using Evolutionary Optimisation and Associative Geometry
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 243-254
summary	This paper describes the usage of parametric design and evolutionary optimisation techniques in architect-engineer collaborations. It discusses the apparent challenges in setting up a trans-disciplinary working-platform that cuts across profession-specific boundaries and negotiates between the otherwise distinct work-methodologies through the use of intelligent CAAD applications. Two approaches to architectural form finding have been combined in this research. The first, parametric design, uses a proprietary package as a key element to the organisation and reorganisation of architectural design. By doing so, it is providing it with intrinsic flexibility allowing designers to go beyond form and accommodate performance data for versioning. The second, ESO (Evolutionary Structural Optimisation), is an engineering tool based on the use of finite element analysis (FEA) capable of optimising the formal geometry of an object to obtain minimum volume under even stress-distribution through an iterative design process. In undertaking this research it became apparent that different levels of resolution need to be addressed in the form-finding process in order to investigate the full potential of the interactive use of parametric design and evolutionary optimisation. The case studies reflect this diversity and demonstrate more successes, limitations and future challenges within the transdisciplinary, collaborative effort.

summary	This paper presents a 24 degree of freedom input device for 3D modeling. iSphere uses the proximity information of pulling-out and pressing-in capacitive sensors to manipulate 12 control points of a 3D surface simultaneously . The iSphere dodecahedron is demonstrated manipulating an analog parametric model with high-level modeling concepts like push or pull the 3D surfaces. Our pilot experiment shows that iSphere saved many steps of selecting the control point and going through menus. Experts were used to those extra steps and still found themselves doing them but novices saved significant time for surface shaping tasks. 3D systems are benefited to execute high-level modeling commands, but lacking of fidelity is a great issue of analog input device.

title	Collective Pavilions: A Generative Architectural Modelling for Traditional Chinese Pagoda
source	Learning from the Past a Foundation for the Future [Special publication of papers presented at the CAAD futures 2005 conference held at the Vienna University of Technology / ISBN 3-85437-276-0], Vienna (Austria) 20-22 June 2005, pp. 129-138
summary	This paper investigates generative architectural modelling for traditional Chinese architecture and aims to explore and extend the potential of adaptive computing for architectural design methods. The design manners analysis of traditional pagodas architectures is made in a holistic view and under historical perspective. We propose a descriptive model and generative system for the design of traditional Chinese pagodas, by which each pagoda is defined as a collection of style-matched and form-coordinated pavilions and described by both topological graphs and variant geometrical units. Our approach models both of the building geometry and space organization/spatial patterns of pagodas separately. The generative mechanism consists of a framework of grammar-based design and parametric, recursive shape computation. Accordingly, the generative algorithm is also made of two levels, the topology of spatial patterns and the shape geometrical parameters that characterize pavilion variations. The algorithm for computing the former is based on GP (Genetic Programming) and the latter GA (Genetic Algorithms). To explore the collective behaviour of a group of pavilions, multi-agent modelling approach is incorporated in composition patterns search. A prototype system, 'glPagoda', using the OpenGL graphics library for rendering and visualization, has been developed and implemented on PC windows platform.

summary	“Why do we have to change? We’ve been building buildings for years without CATIA?” Roger Norfleet, a practicing architect in his thirties poses this question to Tim Quix, a generation older and an expert in CATIA, a computer-aided design tool developed by Dassault Systemes in the early 1980’s for use by aerospace engineers. It is 2005 and CATIA has just come into use at Paul Morris Associates, the thirty-person architecture firm where Norfleet works; he is struggling with what it will mean for him, for his firm, for his profession. Computer-aided design is about creativity, but also about jurisdiction, about who controls the design process. In Architecture: The Story of Practice, Architectural theorist Dana Cuff writes that each generation of architects is educated to understand what constitutes a creative act and who in the system of their profession is empowered to use it and at what time. Creativity is socially constructed and Norfleet is coming of age as an architect in a time of technological but also social transition. He must come to terms with the increasingly complex computeraided design tools that have changed both creativity and the rules by which it can operate. In today’s practices, architects use computer-aided design software to produce threedimensional geometric models. Sometimes they use off-the-shelf commercial software like CATIA, sometimes they customize this software through plug-ins and macros, sometimes they work with software that they have themselves programmed. And yet, conforming to Larson’s ideas that they claim the higher ground by identifying with art and not with science, contemporary architects do not often use the term “simulation.” Rather, they have held onto traditional terms such as “modeling” to describe the buzz of new activity with digital technology. But whether or not they use the term, simulation is creating new architectural identities and transforming relationships among a range of design collaborators: masters and apprentices, students and teachers, technical experts and virtuoso programmers. These days, constructing an identity as an architect requires that one define oneself in relation to simulation. Case studies, primarily from two architectural firms, illustrate the transformation of traditional relationships, in particular that of master and apprentice, and the emergence of new roles, including a new professional identity, “keeper of the geometry,” defined by the fusion of person and machine. Like any profession, architecture may be seen as a system in flux. However, with their new roles and relationships, architects are learning that the fight for professional jurisdiction is increasingly for jurisdiction over simulation. Computer-aided design is changing professional patterns of production in architecture, the very way in which professionals compete with each other by making new claims to knowledge. Even today, employees at Paul Morris squabble about the role that simulation software should play in the office. Among other things, they fight about the role it should play in promotion and firm hierarchy. They bicker about the selection of new simulation software, knowing that choosing software implies greater power for those who are expert in it. Architects and their collaborators are in a continual struggle to define the creative roles that can bring them professional acceptance and greater control over design. New technologies for computer-aided design do not change this reality, they become players in it.

summary	This paper explores new ways to integrate manufacturing processes information in to design phases. Through the analysis of related fields and looking at the relations between its design methods and production processes, we analyze design processes and design representations that already have embedded in them specific ways to materialize through production the artifacts they define. Subsequently, we explore curved surface fabrication using cutting and bending technologies. As a summary, we conceptualize from this top-down development approach to design a framework that integrates design and construction in architecture, based on three possible applications fields: - Design processes improvement - Building production process improvement - CAD-CAM Tools development.
