title	Reconsidering the Construction of Complex Architectural Shapes: On the practical significance of Orthogonal Circle Packings in the creation of Architectural Freeform Structures
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 1, Graz, 20-22 September 2023, pp. 357–366

summary	Key issues to provide economically viable solutions in the creation of doubly curved architectural structures lie in reducing the complexity of supporting and connecting elements, the repetition of costly parts, and the proper rationalization of the building skin. This can, next to post-rationalization techniques, be achieved by applying constrained design approaches where analytical findings are understood in advance and considered throughout the whole planning process. Therefore, we address the design and construction of architectural freeform structures which are derived from orthogonal circle packings. Applying conformal transformations on such configurations turn out to provide a promising base regarding further specifications in simplified fabrication, materialization, and assembly of doubly curved structures. This approach, so far intensely examined by the fields of discrete differential geometry, is here investigated by a research team from the field of architectural sciences. We introduce a computational setup, starting with an orthogonal circle packing in the Complex plane. By combining particular conformal mappings, we obtain a rich variety of conformally discretized surfaces of distinct type. While performing the abovementioned transformations, valuable geometric conditions allowing the usage of simplified and repetitive building components are preserved. The setup provides an intuitive, easily accessible digital workflow from global surface construction and preliminary geometric model representation, yielding a guiding framework purposing the construction of individual building components. We introduce several shape explorations from this setup, give insights to materialization and construction techniques and synchronously discuss their particularities considering both geometric, architectural as well as structural qualities.

title	The Database Revisited: Beyond the Container Metaphor

summary	The growth of international networks, and of international trade in general, has increased the opportunities for architects to work together over distance. In our practice at Pacific Architecture, we’ve been using first modems, and now the Internet, to connect co-workers at sites in Australia, Oregon, Scotland, and Papua New Guinea. Design collaboration has been primarily through the e-mail exchange of text and drawings. We’ve also assessed other CMC tools. Products like Timbuktu and video-conferencing software allow for real-time collaboration, based on the metaphor of two (or more) people together at a table, able to see and hear each other, and to work together on the same document. Groupware make intragroup communication the basis for building a workgroup’s knowledgebase. On recent projects, we’ve begun using database software as the basis for collaborative design communication. We’ve taken as a model for data structure Christopher Alexander’s ‘pattern language’ schema. Conversations about the design take the form of a collaborative construction of the language. Inputs into the database are constrained by the ‘pattern’ format. The CAD drawings run in parallel, as an ‘expression’ or ‘instance’ of the language. So far, CAD and database do not have an integrated interface. This paper describes our experience in these projects. It also outlines a set of design criteria for an integrated CAD/database environment economically and incrementally achievable within the constraints of currently available software. Formulating such criteria requires the reconceptualisation of notions of ‘database’. This paper looks at these notions through philosophical and linguistic work on metaphor. In conclusion, the paper analyses the way in which we can use a reframed notion of database to create a useful collaborative communication environment, centred on the architectural drawing.

summary	This paper presents how a situated agent model can wrap around a design optimization tool and construct concepts from interaction between the agent, the design problem and the use of the tool. The agent develops its structure and behaviour specific to what it is confronted with - its experience. As a consequence, designers can integrate their expertise with the learning results from the agent to develop design solutions. We present preliminary results.

title	Exploring Heuristics Underlying Pedestrian Shopping Decision Processes - An application of gene expression programming
source	Van Leeuwen, J.P. and H.J.P. Timmermans (eds.) 2006, Innovations in Design & Decision Support Systems in Architecture and Urban Planning, Dordrecht: Springer, ISBN-10: 1-4020-5059-3, ISBN-13: 978-1-4020-5059-6, p. 121-136
summary	Most analytical pedestrian behavior researches use utility-maximizing models and have paid less attention to models based on alternative behavioral theories such as bounded rationality. Consequently, there is a lack of deeper explorations into the decision processes of pedestrians. This lack of such alternative models may also be the result of inappropriate methods to estimate such models. For this reason, the paper first introduces a modeling platform GEPAT which has the ability to estimate parallel functions using a multi-gene-sectional chromosome structure and to facilitate building models using processors emulating simple decision mechanisms. The going-home decision of pedestrians in Wang Fujing Street is taken as an example to illustrate the use of GEPAT. The most important conclusion from a comparison of the MNL, hard cut-off, soft cut-off and hybrid model is that the satisficing heuristic fits better to the problem structure, at least in this case, than the utility-maximizing rule does. This example also shows the flexibility of GEPAT as a modeling toolbox and the power of estimating complex models.

title	Responsive Robotic Assembly System With Heterogeneous Materials: A Case Study with Unprocessed Wood
source	ACADIA 2023: Habits of the Anthropocene: Scarcity and Abundance in a Post-Material Economy [Volume 2: Proceedings of the 43rd Annual Conference for the Association for Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9891764-0-3]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 352-360.
summary	This paper explores how robotic automated assembly can be adapted towards archi- tectural materials, and develops a dual planning and design framework between ROS (Robot Operating System) and Grasshopper for responsive assembly with non-stan- dardized tree branches. The framework synthesizes features of adaptive path planning, material analysis, and parametric design as an efficient and dynamic feedback system to adjust robot trajectory planning and design decision-making. It creates the potential for adaptive mass-customized fabrication with heterogeneous natural materials. The paper documents iterate research and testing leading to a series of prototypes using wood branches collected in local parks and forests as test materials. Approaching these through a bi-directional, real-time system, we bypass industrial standardization; confront geometric and tectonic challenges unique to irregular, biological forms; and evaluate the system's performance. The framework embodies techniques in 3D map generation and calibration through sensors, empirical design solver, and data efficiency organization. This distributed, resourceful approach to fabrication challenges the historical tendency of automation technologies towards increased mass standardization and capital concentra- tion. The attention to direct employment of non-standardized raw wood not only supports biologically inspired computational designs, but also ecologically friendly fabrication practices that scavenge waste materials and save costs from material-standardization treatment. Responding to the global concerns of waste management and resource repur- posing, the research seeks to contribute towards an equitable, ecological, architectural design practice with computation and semi-autonomous robots.

summary	Folding is not only a design operation of shaping but also a philosophy theory from Deleuze (Deleuze 1988) which was adopted by architecture. Basically, folding constitutes to forming and topology, which often delivered a mathematical and philosophical expression in generating 3D architectural form. For instance, the work of Eisenman (Eisenman 2003), Libeskind and Lynn (Lynn 1998), they use folding as inspiration to explore the textural folding and bifurcation meaning in the process of form-making. While exploring the meaning of folding, their ideas are expressed by the form using computational tools. Therefore, if a suitable or inspirable tool like our Folding Space (FoS) could be available, such action –fold can be expressed further in the form exploration process.

title	EO-PLAN-GIS Operational earth observation applications involving user communities on national and European level
source	CORP 2003, Vienna University of Technology, 25.2.-28.2.2003 [Proceedings on CD-Rom]
summary	The joint GeoVille/ARC Seibersdorf project EO-Plan-GIS has the objective of deriving Earth Observation (EO)/Geographic Information System (GIS) products for public and private customers (i.e. Austrian state governments and digital mapping industry). Representatives of three state administrations (i.e. Carynthia, Upper Austria and Vorarlberg) and of Tele Atlas (a commercial enterprise in the production of digital road databases) have been actively involved in the project activities. The major focus of the project is on the automated differentiation of built-up areas and the derivation of land use/cover data for both the state governments and Tele Atlas, as well as on the update and upgrade of the Tele Atlas road network. Using GIS methods, the EO-derived base data will be adapted to serve the individual user needs (i.e. Geographic State Information Systems and Tele Atlas MultiNet). EO-Plan-GIS was initiated by the Austrian Ministry of Transport, Innovation and Technology as a national initiative within theframework of the current GMES (Global Monitoring for Environment and Security) activities of ESA and the EU. It delivers inputs into the following GMES domains:• European Regional Monitoring, Subtopic A: Land cover change in Europe, characterisation of land cover changes (1950 –2000) in the EU with particular emphasis on landscapes and urban areas.• Horizontal Support Action – Information Management Tools & the Development of a European Spatial Data“Infostructure”.

summary	Living organisms have evolved effective structural solutions in response to the inherent constraints of their respective environments through a process of morphological adaptation. Given the fact that the majority of natural load bearing materials are fibrous composites, the authors suggest the analysis of appropriate biological role models as a promising strategy for informing the application of fibre reinforced polymers (FRP) in architecture. In this paper the authors present a biomimetic design methodology for seamless large-scale FRP structures involving the analysis of the exoskeletons of Arthropoda with regards to structural performance criteria, the development of a custom robotic filament winding process, and the translation of biological and fabricational principles into the architectural domain through physical prototyping and the development of custom digital tools. The resulting performative material system is evaluated in a full-scale research pavilion.

title	Polygon Comparison Using a Graph Representation
source	SIGGRAPH '80 Conference Proceedings July, 1980. vol. 14 ;no. 3: pp. 10-18 : ill. includes bibliography.
summary	All of the information necessary to perform the polygon set operations (union, intersection, and difference) and therefore polygon clipping can be generated by a single application of a process called polygon comparison. This process accepts two or more input polygons and generates one or more polygons as output. These output polygons contain unique homogenous areas, each falling within the domain of one or more input polygons. Each output polygon is classified by the list of input polygons in which its area may be found. The union contour of all input is also generated, completing all of the information necessary to perform the polygon set operations. This paper introduces a polygon comparison algorithm which features reduced complexity due to its use of a graph data representation. The paper briefly introduces some of the possible approaches to the general problem of polygon comparison including the polygon set and clipping problems. The new algorithm is then introduced and explained in detail. The algorithm is sufficiently general to compare sets of concave polygons with holes. More than two polygons can be compared at one time; all information for future comparisons of subsets of the original input polygon sets is available from the results of the initial application of the process. The algorithm represents polygons using a graph of the boundaries of the polygons. These graphs are imbedded in a two dimensional geometric space. The use of the graph representation simplifies the comparison process considerably by eliminating many special cases from explicit consideration. Polygon operations like the ones described above are useful in a variety of application areas, especially those which deal with problems involving two dimensional or projected two dimensional geometric areas. Examples include VLSI circuit design, cartographic and demographic applications, and polygon clipping for graphic applications such as viewport clipping, hidden surface and line removal, detailing, and shadowing

title	The Architecture of Flows: Integrated Infrastructures and the ‘Metasystem’ of Urban Metabolism
source	ACADIA 11: Integration through Computation [Proceedings of the 31st Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA)] [ISBN 978-1-6136-4595-6] Banff (Alberta) 13-16 October, 2011, pp. 40-43
doi	https://doi.org/10.52842/conf.acadia.2011.040
summary	The traditional approach to urban design studies has been based on what can be described as a generalised anatomical model, e.g., functional zoning coupled to metaphors such as green areas serving as the ‘lungs’ of cities. Despite the frequent use of biological metaphors, urban design has generally proceeded from an understanding of cities as static arrays of buildings and infrastructures that exist in, but are distinct from, stable environments. But this approach does not reflect the dynamic systems of cities throughout history, nor their close coupling to the dynamics of their local environment, climate and ecology, and now the global dynamics of culture and economy. The limitations of this approach, in which cities are treated as discrete artefacts, rather than nodes interconnected by multiple networks, are compounded by the legal and regulatory boundary of the city usually being defined as an older core, so that cities are regarded as something quite separate from their surrounding territory. All cities have administrative boundaries, but cities are very rarely either physically or energetically contained within those administrative boundaries. In the past, cities gathered most of the energy and materials they needed from their immediate local territory, and trade linked systems of cities across whole regions. The growth and vitality of many cities are no longer dependent on the spatial relationship with their immediate environs but on the regional and global flows of resources. The flow of materials, information and energy through cities comes from far outside their physical and regulatory (municipal) boundaries. Cities now extend their metabolic systems over very great distances, so that the extended territory of the urban metabolism of a city and its geographical ‘place’ are often completely decoupled.

title	Anatomy of a Building - Introducing interactive RGB lenses for architectural data visualization

doi	https://doi.org/10.52842/conf.ecaade.2019.1.739
summary	The paper proposes an alternative way to present architectural information, using color filters - specifically RGB lenses - as an interface to emphasize or reveal the internal structure or hidden logic of an architectural artifact. In an interplay of analogue and digital techniques, it employs rules of color blocking in order to highlight certain aspects of complex buildings, urban plans, or interiors, which cannot be discovered using conventional visualization methods. In this research, the authors developed an interactive RGB lens-interface and techniques for superimposed color visualizations that can be used for an enhanced visualization of the internal structure of a building. By applying physical or digital color lenses, viewers can perceive individual layers of project visualizations, in order to understand certain tectonic or construction logics, such as skin, structure or infrastructure. Based on existing bibliography, the paper presents the workflow from drawing, 3D model or photograph to RGB visualization, through a series of test case scenarios applicable to the field of architecture and design.

title	Analogue Computation: An educational framework for introducing first-year architecture students to parametric design through manual making

doi	https://doi.org/10.52842/conf.ecaade.2023.1.011
summary	This paper describes an educational framework for introducing first-year architecture students to concepts of parametric design through manual making, without the use of digital tools. Responding to shifts in our current society and culture, the authors developed a new curriculum for the first-year-course “Architectural and Artistic Design” at the FH JOANNEUM University of Applied Sciences and refined it over the last three years. The intention was to prepare students to their highly digitized future careers in architecture, by focusing on the thinking process, the major aspect of parametric design. The didactic concept of using analog tools reacts to the digital saturation of Generation Z students, and the post-digital re-awareness of physical and material aspects. Students engaged in a series of small tasks in open-ended “design through making” processes, applying parametric concepts for experimental form finding. The course assignment was to design a modular spatial structure, based on adjustable parameters of module geometry, connection strategy, and assembly logic. The results were assessed through student feedback and demonstrate the educational and creative value of this pedagogical approach and indicate that the students improved their understanding of parametric design as a thinking process beyond current technologies.

summary	This research explores the relationship between digital design and digital fabrication, investigating robotic fabrication as a dynamic design process. It examines the potential of utilizing production tools as the key part of the design process, where the final geometry is neither simulated nor pre-defined in the digital realm before materialization. This “design-fabrication” or “design-by-fabrication” workflow fosters a new way of thinking about architectural design and practice, as well as unlocking creativity and discovering new geometries and aesthetics. To illustrate this, the paper presents a series of directed design experiments developed by students in two seminars at Graz University of Technology. A unique fabrication technique is investigated, combining laser cutting and robotic thermoforming, which was developed by the author in the course of her PhD-research. Utilizing this robotically aided design process, sheets of acrylic glass are laser cut and thermoformed by a robot into 3- dimensional spatial objects, each element with individual geometries, textures, transparencies and apertures.

summary	This study investigates design opportunities fostered by fabrication processes, ex-ploring manual and robotic forming. It links handcraft and digital fabrication techniques by implementing a motion capture system. It suggests physical prototyping as a novel form of design research, operating in the dynamic field between human capabilities, machine skills, and material behavior. This paper presents a series of experimental case studies created in a seminar taught by the author at Graz University of Technology. In this course, students con-duct tactile experiments, forming panels by hand and by robot, guided by the material behav-ior and reaction. Thereby, they explore the creation of architectural form in a dynamic inter-play between human, machine and material. Movement and speed of hand forming proce-dures are recorded into digital data, and then converted into machine code, driving a 6-axis industrial robotic arm. By using the same set-up for manual and robotic forming, both pro-cesses are relatable.

summary	This paper presents experimental research about using Augmented Reality (AR) for interactive design processes, exploring a spatial "live" design method taking place in an overlay of real space and digital models. It discusses the processes and outcomes of a seminar undertaken at Graz University of Technology in winter term 2020/2021. Due to the Covid-19 pandemic, the course was taught online, and conceptualized to allow students the biggest possible learning experience during the lockdown. Ensuring accessibility to all participants, the seminar was based on the use of ubiquitous devices. The implementation of newly developed software, such as "Fologram", enabled the students to use AR systems at home with their personal computers and smartphones. The task of the course was to design customized interventions for the students' own domestic spaces, reacting to changing conditions and needs during the lockdown. The employed workflow was driven by an instant connection between 3D-modeling (Rhinoceros3D), parametric design (Grasshopper) and holographic immersion (Fologram).

The paper opens with a review of existing research on the notion of topological interlocking. It then presents a catalogue that characterizes the various types of topological interlocking systems and compares the potential of these types to be employed in architectural design. This is followed by a discussion regarding the results of fabrication experiments that examine the specific types, which appear to have the best potential for architectural design.

title	Topological interlocking in architecture: A new design method and computational tool for designing building floors
source	International Journal of Architectural Computing vol. 15 - no. 2, 107-118
summary	This article presents a framework for the design process of structural systems based on the notion of topological interlocking. A new design method and a computational tool for generating valid architectural topological interlocking geometries are discussed. In the heart of the method are an algorithm for automatically generating valid two-dimensional patterns and a set of procedures for creating several types of volumetric blocks based on the two-dimensional patterns. Additionally, the computational tool can convert custom sets of closed planar curves into structural elements based on the topological interlocking principle. The method is examined in a case study of a building floor. The article concludes with discussions on the potential advantages of using the method for architectural design, as well as on challenging aspects of further development of this method toward implementation in practice.

summary	We present a newapproach to interactivemodeling of freeform surfaces. Instead of a fixed mesh of control points, the model presented to the user is that of an infinitely malleable surface, with no fixed controls. The user is free to apply control points and curves which are then available as handles for direct manipulation. The complexity of the surface's shape may be increased by adding more control points and curves, without apparent limit. Within the constraints imposed by the controls, the shape of the surface is fully determined by one or more simple criteria, such as smoothness. Our method for solving the resulting constrained variational optimization problems rests on a surface representation scheme allowing nonuniform subdivision of B-spline surfaces. Automatic subdivision is used to ensure that constraints are met, and to enforce error bounds. Efficient numerical solutions are obtained by exploiting linearities in the problem formulation and the representation.

title	Free-Form Shape Design Using Triangulated Surfaces
source	Computer Graphics, no. 28, pp. 247-256
summary	We present an approach to modeling with truly mutable yet completely controllable free-form surfaces of arbitrary topology. Surfaces may be pinned down at points and along curves, cut up and smoothly welded back together, and faired and reshaped in the large. This style of control is formulated as a constrained shape optimization, with minimization of squared principal curvatures yielding graceful shapes that are free of the parameterization worries accompanying many patch-based approaches. Triangulated point sets are used to approximate these smooth variational surfaces, bridging the gap between patch-based and particle-based representations. Automatic refinement, mesh smoothing, and re-triangulation maintain a good computational mesh as the surface shape evolves, and give sample points and surface features much of the freedom to slide around in the surface that oriented particles enjoy. The resulting surface triangulations are constructed and maintained in real time.
