title	The Resolution of Architecture in the Digital Age
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 347-357.
summary	The resolution of architecture is a measure of the spatial density of information inherent in a building. This paper demonstrates how the confluence of advances in computational design and additive manufacturing has recently led to a paradigm shift in potential architectural resolution. Buildings can now be designed and fabricated with elements at the threshold of human perception. This resolution can be used to replicate existing architectural styles ever more efficiently and accurately. Yet as with the introduction of other new technologies, architects must now explore the latent potentials and determine what kind of new architectures become conceivable. Specifically, what architectures can adequately express this enormous resolution and the unlimited geometric complexity within reach? With the project Digital Grotesque, we present the first human-scale, enclosed structure that truly exploits these opportunities. Algorithms are used to articulate and orchestrate the geometry from the macro scale down to 1mm small details. The structure is enriched with local information at a previously unseen resolution. A unique language of form is developed that transcends rationality and celebrates spatial expression: a digital exuberance.

title	Reconfigurable Formwork System for Vision-Informed Conformal Robotic 3D Printing

summary	Robotic additive manufacturing has garnered significant research and development interest due to its transformative potential in architecture, engineering, and construction as a cost-effective, material-efficient, and energy-saving fabrication method. However, despite its potential, conventional approaches heavily depend on meticulously optimized work environments, as robotic arms possess limited information regarding their immediate surroundings (Bechthold, 2010; Bechthold & King, 2013). Furthermore, such approaches are often restricted to planar build surfaces and slicing algorithms due to computational and physical practicality, which consequently limits the feasibility of robotic solutions in scenarios involving complex geometries and materials. Building on previous work (Çapunaman et al., 2022), this research investigates conformal 3D printing of clay using a 6 degrees-of-freedom robot arm and a vision-based sensing framework on parametrically reconfigurable tensile hyperbolic paraboloid (hypar) formwork. In this paper, we present the implementation details of the formwork system, share findings from preliminary testing of the proposed workflow, and demonstrate application feasibility through a design exercise that aims to fabricate unique components for a poly-hypar surface structure. The formwork system also offers parametric control over generating complex, non-planar tensile surfaces to be printed on. Within the scope of this workflow, the vision-based sensing framework is employed to generate a digital twin informing iterative tuning of the formwork geometry and conformal toolpath planning on scanned geometries. Additionally, we utilized the augmented fabrication framework to observe and analyze deformations in the printed clay body that occurs during air drying. The proposed workflow, in conjunction with the vision-based sensing framework and the reconfigurable formwork, aims to minimize time and material waste in custom formwork fabrication and printing support materials for complex geometric panels and shell structures.

summary	This ongoing investigation aims to learn from nature novel material organizations and structural systems in order to develop innovative architectural system. We developed a multidisciplinary approach, using scientific analysis and design research and prototyping. We focus on the study of a “living fossil” fish, whose armor system is so efficient it has remained almost unchanged for millions of years. We investigate its morphological characteristics, its structural properties, the assembly mechanisms and the underlying material properties in order to derive new principles to design new enhanced structural systems. We use micro computerized tomography and scanning electron microscopy to observe microstructures, parametric design to reconstruct the data into digital models and then several 3D printing technologies to prototype systems with high flexibility and adaptive capabilities, proposing new gradual material interfaces and transitions to embed performative capabilities and multifunctional potentials.

title	New Methods for the Rapid Prototyping of Architectural Models
doi	https://doi.org/10.52842/conf.ecaade.2013.2.397

summary	Various Rapid Prototyping methods have been available for the production of physical architectural models for a few years. This paper highlights in particular the advantages of 3D printing for the production of detailed architectural models. In addition, the current challenges for the creation and transfer of data are explained. Furthermore, new methods are being developed in order to improve both the technical and economic boundary conditions for the application of 3DP. This makes the production of models with very detailed interior rooms possible. The internal details are made visible by dividing the complex overall model into individual models connected by means of an innovative plug-in system. Finally, two case studies are shown in which the developed methods are applied in order to implement detailed architectural models. Additional information about manufacturing time and costs of the architectural models in the two case studies is given.

title	Freeform Surfaces Adaptation through Developable Surfaces Using Apparent Contours
source	Global Design and Local Materialization[Proceedings of the 15th International Conference on Computer Aided Architectural Design Futures / ISBN 978-3-642-38973-3] Shanghai, China, July 3-5, 2013, pp. 358-367.
summary	Free-form surfaces construction has been limited to the possibilities of graphical and constructive control. In a few years we have seen an important development of control of the form through digital graphic technology, software and hardware that allowed truly spectacular constructions. A significant researching way not only in architecture, but also in engineering even in sculpture, has been the adaptation of free forms through developable surfaces using different systems, many based on differential geometry. Reinterpreting some topics of projective geometry that allows the use of certain CAD software, jumping from the physical to the digital drawing system, has been developed a method allows the adaptation of free forms through developable surfaces using apparent contours that we can draw over these free form surfaces. Trough using them we can trace two types of developable surfaces as cones and cylinders that are touching the surface tangentially to this contours.

title	Tessellating Freeform Surfaces with Boundary – Driven Analysis
doi	https://doi.org/10.52842/conf.caadria.2013.873
source	Open Systems: Proceedings of the 18th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2013) / Singapore 15-18 May 2013, pp. 873-882
summary	In this paper, we look at the surface tessellation problem, in particular, the problem of meshing a surface with the added consideration of incorporating constructible building components. When a surface is tessellated into discrete counterparts, certain conditions usually occur on the surface boundaries that are caused by trimming operations; for example, irregularly shaped panels at the trimmed edges. We present an algorithmic approach to tessellating quad-dominant mesh surfaces to deal with such irregular boundary conditions, and demonstrate its application through surface subdivision examples.

title	The evolution of representation in architecture

summary	This paper proposes an overview on the relation between representation, technology and architecture methodologies. Focusing on disposable digital tools, it reaches the new tools of virtual immersive 3D architectural environments. It also addresses the concepts of operative 3D, augmented reality and robotic manufacturing, thus introducing a system of digital tools that enables users to step inside a 3D virtual reality environment, built as a virtual building prototype, and to use all data instructions directly with the construction industry. This paper questions therefore the traditional processes and perceptions in architecture and draw present and future advanced state-of-the-arts methodologies. As a result, future and tradition in architectural design methods are challenged. Recognizing the permanent tensions between traditional and innovative processes, possible methodological changes are put in perspective, namely the fields of technical representation, building construction and design processes.

title	The Role of the Record and the Paradox of the Original
doi	https://doi.org/10.52842/conf.caadria.2014.317
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 317–326
summary	Earthquakes have progressively destroyed the Chilean built heritage over the years, not only due to the initial devastation they produce, but also as a result of the applied reconstruction approaches that follow. The design of reconstruction projects has usually aimed to re-establish the previous built form of historic buildings; generating new ‘heritage’ constructions that try to imitate only the appearance of previous ones rather than understanding that heritage, in the case studied, includes a sustainable mode of construction. This issue occurs in places where previous records are sometimes non-existent, which poses the question of authenticity. Considering the regularity of earthquakes in Chile, the role of accurate recording technologies, such as 3D laser scanning, becomes relevant. Their implications for new and existing architectures in the re-construction process include being a virtual database for demolition, retrofitting, intervention or replica. This paper examines the survey of the church of San Lorenzo de Tarapacá obtained in January 2013, and discusses how this, in conjunction with previous records, might impact on what is considered heritage and the design of future reconstructions.

summary	This paper describes and provides a critique of the design and implementation of the “scoops” – a set of bespoke multifunctioning architectural free-form concrete elements that are a highlight of the new Soheil Abedian School of Architecture by the office of Sir Peter Cook and Gavin Robotham (CRAB). The development includes the transfer of analogue design processes into digital 3D modelling, which is then analysed and rationalized via an exchange with consultants and procurement contractors. The complexity of the concrete works necessitated the use of digital fabrication to make their implementation affordable and within time constraints, with said complexity creating a variety of challenges for many aspects of the entire delivery team. The 3D model played a critical role in communicating intent and accuracy at all stages. The use of site-based craftsmanship combined with computer aided design and fabrication overlapped to realize the project.

title	Geelong Digital Outdoor Museum (GDOM) - Photogrammetry as the Surface for a Portable Museum
doi	https://doi.org/10.52842/conf.caadria.2022.1.677
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 677-686
summary	This paper presents the development and evaluation of the Geelong Digital Outdoor Museum (GDOM) prototype accessible at https://gdom.mindlab.cloud. GDOM is a portable museum‚our novel adaptation of the distributed museum model (Stuedahl & Lowe, 2013) which uses mobile devices to present museum collections attached to physical sites. Our prototype defines a way for intangible heritage associated with tangible landscapes to be accessible via personal digital devices using 360 3D scanned digital replicas of physical landscapes (photogrammetric digital models). Our work aligns with efforts set out in the UN Sustainable Development Goal 11 (SDG 11) to safeguard cultural and natural heritage, by openly disseminating the heritage of physical sites seamlessly through the landscape. Using a research by design methodology we delivered our prototype as a modular web-based platform that leveraged the Matterport digital model platform. We qualitatively evaluated the prototype's usability and future development opportunities with 32 front-end users and 13 potential stakeholders. We received a wide gamut of responses that included: users feeling empowered by the greater accessibility, users finding a welcome common ground with comparable physical experiences, and users and potential stakeholders seeing the potential to re-create physical world experiences with modifications to the digital model along with on-site activation. Our potential stakeholders suggested ways in which GDOM could be integrated into the arts, education, and tourism to widen its utility and applicability. In future we see design potential in breaking out of the static presentation of the digital model and expanding our portable museum experience to work on-site as a complement to the remote experience. However, we recognise the way in which on-site activation integrate into users' typical activities can be tangential (McGookin et al., 2019) and this would necessitate further investigation into how to best integrate the experience on-site.

title	Fabricate It, Paint It – And Don’t Wait up: Separating Fact from Fiction in Digitally Sponsored Fabrication

summary	This paper offers perspectives on emerging trends in materiality and digital fabrication. It explores effects on communication practices and investigates how this changing materiality of data impacts collaboration and interoperability within design and making. Computer numerical controlled (CNC) routing and laser-cutting services are available in most major cities. Affordable kits for 3D printers, CNC routers and DIY KUKA robots are available across the Internet. A considerable part of the attraction of these tools is the ability to fabricate physical goods without detailed fabrication knowledge. We look at this phenomenon through two sets of examples, making furniture with a CNC router and making robots and tangibles with a 3D printer. In our examples it appears materiality remains an important factor throughout the process. We unpick these examples to shed light on how the technology impacts knowledge practices and ways of thinking during design and making.

title	Working with Multi-scale Material Distributions
doi	https://doi.org/10.52842/conf.acadia.2013.043
source	ACADIA 13: Adaptive Architecture [Proceedings of the 33rd Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-1-926724-22-5] Cambridge 24-26 October, 2013), pp. 43-50
summary	At present, computer aided design (CAD) software has proven ill equipped to manage the spatial variations in material properties. Most digital design packages employ a surface modeling paradigm where a solid object is that which is enclosed by a set of boundaries (known as boundary representations or “B-rep” for short). In surface models, material representations are often treated as homogenous and discrete. Yet, natural materials are capable of structures where the variability of material within a volume is defined at a multiplicity of scales and according to various functional criteria. With the advent of new 3D printing techniques, a new possibility emerges—allowing new multi-material composite objects to be fabricated in a single build volume with a high degree of dimensional accuracy and repeatability. However, a big limitation facing complex high resolution digital fabrication comes from the software’s inability to represent or handle material variability. This paper proposes a new digital interface for working with multi-material distributions at a variety of scales using a rasterization process. Beyond the immediate benefit of precise graduated control over the material distribution within a 3D printed volume, our interface opens new creative opportunities by enabling the use of existing image processing techniques (such as filtering, mapping, etc.) which can be applied to three-dimensional voxel fields. Examples are provided which explore the potential of multi-scale material distributions.

summary	MOLIT authorised Indoor Spatial Information as Basic spa- tial information in 2013. It became a legal evidence for constructing and managing Indoor Spatial Information. Although it has a little ad- vantage to utilise as service level that Indoor Spatial Information by laser scan or measurement, it has a lot of problems such as consuming many resources, requiring additional progresses for inputting Object Information. In conclusion, it is inefficient to utilise for the mainte- nance and domestic AEC/FM field. The purposes of this study is to output Indoor Spatial Information by operating IFC model which based on open BIM and to improve availability of Indoor Spatial In- formation with data visualisation. The open-sources of IFC Exporter, an inner program of Revit, is used to output Indoor Spatial Infor- mation. Directs 3D Library is also operated to visualise Indoor Spatial Information. It is possible to inter-operate between XML format and the objects of Indoor Spatial Information. It can be utilised in various field as well. For example COBie linkage in facility management, construction of geo-database using air-photogrammetry of UA V , the simulation of large-scale military operations and the simulation of large-scale evacuation. The method that is purposed in this study has outstanding advantages such as conformance with national spatial in- formation policy, high level of interoperability as indoor spatial in- formation objects based on IFC, convenience of editing information, light level of data and simplifying progress of producing information.

title	Statically Motivated Form Finding Based on Extended Graphical Statics (EGS)

summary	In the 19th century it was common to use graphical methods for study the relationship between form and force. The central element of all drawing methods for representing the inner flow of forces was the investigation of the dependence of equilibrium and force polygons, as well as their representation in two geometrically dependent diagrams with different units. This research is part of an on going project to extend the methods of ‘graphical statics’ of Carl Culmann (1866) to the third dimension in order to overcome some of the 2D-limitations of this approach. It is focused on the construction of resulting force within 3D and the utilization within discrete space frames (tetrahedrons) in equilibrium. The objective of the EGS is to focus on constructing in contrast to calculating. That means that the logic of the inner force flow leads to a process-oriented and visible approach of design, which gets computationally accessible. With the use of digital tools and increasing importance of performative methods of form-finding a renewed interest in these vector-based geometric methods of construction of force flow has occurred. This may be will give the possibility to get an alternative to the common form finding methods by relaxation processes and analysis by FEM.

summary	Cellular automata (CA) is a well-known computation method introduced by John von Neumann and Stanislaw Ulam in the 1940s. Since then, it has been studied in various fields such as computer science, biology, physics, chemistry, and art. The Classic CA algorithm is a calculation of a grid of cells' binary states based on neighboring cells and a set of rules. With the variation of these parameters, the CA algorithm has evolved into alternative versions such as 3D CA, Multiple neighborhood CA, Multiple rules CA, and Stochastic CA (Url-1). As a rule-based generative algorithm, CA has been used as a bottom-up design approach in the architectural design process in the search for form (Frazer,1995; Dinçer et al., 2014), in simulating the displacement of individuals in space, and in revealing complex relations at the urban scale (Güzelci, 2013). There are implementations of CA tools in 3D design software for designers as additional scripts or plug-ins. However, these often have limited ability to create customized CA algorithms by the designer. This study aims to create a customizable framework for 3D CA algorithms to be used in 3D form explorations by designers. Grasshopper3D, which is a visual scripting environment in Rhinoceros 3D, is used to implement the framework. The main difference between this work and the current Grasshopper3D plug-ins for CA simulation is the customizability and the real-time control of the framework. The parameters that allow the CA algorithm to be customized are; the initial state of the 3D grid, neighborhood conditions, cell states and rules. CA algorithms are created for each customizable parameter using the framework. Those algorithms are evaluated based on the ability to generate form. A voxel-based approach is used to generate geometry from the points created by the 3D cellular automata. In future, forms generated using this framework can be used as a form generating tool for digital environments.

summary	In this paper, we propose a new approach to simulating users’ behavior in yet un-built buildings. For this purpose, we have developed a model that connects two different representations: a formal representation of the building use, by means of a method borrowed from Business Process Modeling and Notation (BPMN) approach; and a game-engine based 3D virtual environment, where this process is effectively simulated and integrated with some autonomous behaviour of users/agents. The model has been applied to two test cases, where the activities of doctors, nurses, patients, and visitors in different hospitals were tracked, simulated, and reviewed by medical professionals for validation.
