title	“Seeing” with the Hands: Teaching Architecture for the Visually-Impaired with Digitally-Fabricated Scale Models
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. 159-166.
summary	Accessibility of information for the visually-impaired has greatly benefited from information and communication technologies (ICT’s) in the past decades. However, the interpretation of images by the blind still represents a challenge. Bidimensional representations can be understood by those who have seen at least sometime in their lives but they are too abstract for those with congenital blindness, for whom three-dimensional representations are more effective, especially during the conceptualization phase, when children are still forming mental images of the world. Ideally, educators who work with the visually-impaired should be able to produce custom 3D models as they are needed for the explanation of concepts. This paper presents an undergoing project that aims at developing a protocol for making 3D technologies technically and economically available to them.

summary	The nature of the architectural design process can be described along the lines of the following representational devices: the plan and the model. Plans can be considered one of the oldest methods to represent spatial and aesthetic information in an abstract, 2D space. However, to be used in the design process of 3D architectural solutions, these representations are inherently limited by the loss of rich information that occurs when compressing the three-dimensional world into a two-dimensional representation. During the first Digital Turn (Carpo 2013), the sheer amount and availability of models increased dramatically, as it became viable to create vast amounts of model variations to explore project alternatives among a much larger range of different physical and creative dimensions. 3D models show how the design object appears in real life, and can include a wider array of object information that is more easily understandable by nonexperts, as exemplified in techniques such as building information modeling and parametric modeling. Therefore, the ground condition of this paper considers that the inherent nature of architectural design and sensibility lies in the negotiation of 3D space coupled with the organization of voids and spatial components resulting in spatial sequences based on programmatic relationships, resulting in an assemblage (DeLanda 2016). These conditions constitute objects representing a material culture (the built environment) embedded in a symbolic and aesthetic culture (DeLanda 2016) that is created by the designer and captures their sensibilities.

summary	This research explains the development process of a design tool that can construct complex surface geometries using only two-dimensional plan drawings. The intention behind this tool is to address certain complex behavior of surface geometries such as hydrological characteristics. This paper briefly explains the historic and mathematic description of surface data structures, according to Cayley, Maxwell and Morse. This is followed by a brief introduction of the surface network/critical graph extraction technique in GIS. Additionally, the algorithm of contour extraction from asimple critical graph to reconstruct a surface is explained. In the final section the lessons learnedfrom the previous sections are used to develop algorithms for a tool which uses only plan drawings to construct complex surfaces. Three algorithms are explained in the final section among which the third one is considered to be the most complete and promising approach. Therefore,some design examples are presented to show the flexibility of the tool. At the end, this paper provides suggestions and discussions to reflect further ideas in order to improve the tool in future.

title	Maquetes Híbridas: Diálogos Entre as Técnicas Tradicionais e as Tecnologias Digitais no Processo Projetual [Hybrid Models: Dialogues Between Traditional Techniques and Digital Technologies in the Design Process]

summary	This article is about hybrid models, as a kind of three-dimensional representation emerged from of the possibilities of combining traditional techniques with digital technologies. The purpose is to reflect on the possibilities of production and applications of these types of hybrid models, highlighting them as recurring elements of design practice after the rise of new technologies of information and communication, and prototyping and digital manufacturing. By adopting the model as an object of research, we propose to expand the field of reflection on the incorporation of several digital technologies in the design process, specifically aspects of three-dimensional and graphical representation.

title	A Minimal Tension Canopy – Through Investigations of Self-Organised Systems
doi	https://doi.org/10.52842/conf.caadria.2013.147
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. 147-156
summary	The dynamics of a physics-based algorithm which acquires its complex organization through a number of localised interactions applied over a prescribed network can be described as a self-organised system. This in turn has the capacity to define explicit form and space based upon behavioural computational processes with an embedded structural logic. This paper discusses the way in which physics based algorithms can be used to inform the organisation of a compressional structure in a case study. Its structure is based on Hooke’s law of elasticity; which establishes a three dimensional catenary logic through a number of localised interactions applied over an entire network. This is applied to a project with specific constraints to site, boundary conditions and maximising solar gain whilst maintaining structural rigidity. The methodological approach describes the design to assembly process in which the project has been developed. This includes the applied generative design tools in order to establish the self-organised logic, the form finding process, the techniques of design documentation, the fabrication process and the logistics of construction and assembly.

title	Understanding and Managing the Constructive Characteristics of Vernacular Architecture

summary	In this paper a methodology will be presented to investigate and document the constructive characteristics of two raw earth houses: artifacts that belong to the vernacular architecture. The comprehension, analysis and documentation of these architectures presents several problems mainly linked to the impossibility of using a predefined method, because the difficulties relating to each artifact and its characteristics, to particular geographic, cultural and social situations, are unique. To understand and document the constructive features it was decided to realize a three-dimensional digital reconstruction of the two artifacts, using 3D modeling software. Subsequently several graphic works have been elaborated (technological breakdown, sheets with detailed information about the materials, used constructive techniques, etc), useful in managing a recovery or maintenance project.

title	Daylight Prototypes: From Simulation Data to Four-Dimensional Artefact-Physical Metrics Models in Sustainable Design Education
doi	https://doi.org/10.52842/conf.caadria.2013.159
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. 159-168
summary	The increasing use of building performance simulation in architectural design enriches digital models and derived prototyping geometries with performance data that makes them analytically powerful artefacts serving sustainable design. In our class “Parametric Design”, students perform concurrent thermal and daylight optimization during the architectural ideation process, employing digital simulation tools, and also utilize rapid prototyping techniques to produce process artefacts and whole-building analysis models with climate-based day-light metrics physically embedded. Simulation metrics are merged with prototyping geometries to be output on a colour-capable Zprinter; the resultant hybrid artefacts simultaneously allow three-dimensional formal as well as whole-year daylight performance evaluation, rendering analysis scope four-dimensional. They embody a specific epistemological type that we compare to other model instances and posit to be an example of multivalent representation, a formal class that aids knowledge accretion in workflows and allows designers to gain a physically reframed understanding of geometry-performance relationships.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 128-135.
summary	Over the past several decades, the conception and construction of formal complexity has disregarded the realities of material waste, costs, and accessibility. By engaging the isometric relationship between flatness and three-dimensional form, the research shown here investigates how waste-conscious approaches to geometric innovation can create new architectural languages. Specifically, the work deploys a subset of curved-crease folding that uses planar reflections referred to as sectional mirror operations to create unique forms comprised of composite cylindrical and conical surfaces (Figure 1). Whereas known studies in curved-crease folding typically explore singular (one-off, figural) compositions (Davis et al. 2013), this process develops a module aggregation strategy to suggest large inhabitable structures as both figural and field-like conditions.

summary	This paper presents preliminary results from an outgoing research about the Scholarship Program on Technological Development and Innovation (PIBITI), in which we focused the potentiality of Augmented Reality (AR) application on documentation of the architectural heritage according to the UNESCO principles. We took as the object of study of the “Quarteirão dos Trapiches”, one of the historic buildings in Laranjeiras, Sergipe, Brazil, and we reconstructed it digitally with Augmented Reality and subsequently generate a QR Code information associated with this building, available on a website. In this context, this work highlight the potential application of architectural heritage documentation in AR, where discourse about the digital processing RA we use, and the association of this digital model with a history of the building. Finally, we present our conclusions on the use of RA in shareholders highlighting the advantages of three-dimensional visualization of architectural heritage, in an interactive, dynamic and low cost of deployment, pondering the importance of encouraging a policy of initiating development activities and technological innovation to digital architectural documentation.

title	Mesh Grammars – Procedural Articulation of Form
doi	https://doi.org/10.52842/conf.caadria.2013.821
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. 821-829
summary	We introduce a formal grammar as a computational approach to the generation of design. While existing shape-grammars transform primitive shapes as lines or rectangles, the presented production system specifically addresses polyhedral objects described by three-dimensional meshes composed of vertices, edges and faces. The parameters of the transformation rules are sensitive to topological and topographical properties of the selected input mesh. We demonstrate that this approach allows the creation of new ornamental structures and can lead to a new language of architectural forms.

summary	This paper outlines a methodology that enables the construction of complex surface forms resulting from computational design processes by manual means using non-industrial materials. The methodology is based on the craft process of weaving whereby a three-dimensional form can be produced using a flexible, linear material. Construction information from a three-dimensional digital model is communicated tocraftspersons through a set of two-dimensional drawings outlining the sequence of construction and requiring only linear dimensions.

title	The Novel Stones of Venice: The Marching Cube Algorithm as a Strategy for Managing Mass-customisation
doi	https://doi.org/10.52842/conf.acadia.2013.311
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. 311-318
summary	The Marching Cube (MC) algorithm is a simple procedural routine for the surface representation of three- dimensional scalar fields. While much has been written of the algorithm’s efficiencies and adaptive nature within the domain of computer graphics and imaging, little has been explored within the context of architectural geometry and fabrication. This paper posits a novel implementation of the MC algorithm coupled with robotic fabrication (RF) techniques, to realise an open-ended design method that approaches mass-customisation as the unique geometric distortion of a finite set of topologically consistent families of tectonic elements.The disciplinary consequences of this and similar methods that intimately couple algorithmic design techniques with robotic fabrication are discussed. These include the re-affirmation or expansion of the role of the architect as master builder that is enabled by challenging Leon Battista Alberti’s 15th Century division between design concept and building.The method and its disciplinary potentials are illustrated through the description of an installation built by the authors for the Australian Pavilion at the Venice Biennale. Clouds of Venice serves as a case study for a new integrated mode of production, one that increases the quality and number of feedback relations between design, matter and making.

summary	In the context of the growing usefulness of computation within architecture, structures face the potential for being conceived of as intelligent entities capable of resilient, adaptive behavior.Building on this idea, this work explores the use of machine learning for structures that may learn to autonomously “stand up”. The hypothesis is that a neural network with genetically optimized weights would be capable of teaching lightweight, flexible, and unanchored structures to self-rectify after falling, through their interactions with their environment. The experiment devises a physical and a simulated prototype. The machine-learning algorithm is implemented on the virtual model in a three-dimensional physics environment, and a solution emerges after a number of tests. The learned behavior is transferred to the physical prototype to test its performance in reality. This method succeeds in allowing the physical prototype to stand up. The findings of this process may have useful implications for developing embodied dynamic structures that are enabled with adaptive behavior.

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	As technology affine urban landscape researchers,working in Asian mega cities, we roam through crowded and narrow, widely informal city layouts, where we apply digitalfieldwork equipment and conduct design work. We use low cost cameras and camera drones, tools that had been developed asgadgets for outdoor freaks or plaything for nerds. In this paper, we describe recent advances in the development of amethod of on-site data and image gathering, which allows the processing of concrete 3D models of informal city spaces. Thevisual quality of these models is still moderate, but the resulting three-dimensional spatial puzzlemakes a widelyinaccessible and undocumented piece of city terrain visible, understandable and designable.

summary	This paper describes a process of development of three-dimensional virtual models to be viewed in augmented reality through mobile devices. It considers the concept of ubiquitous tourism applied to the tourist rout “the path to the jerked beef farms of Pelotas”, RS. Thus, overlapping models of the buildings related to the history of the jerked beef farms, over the real environment, respond to a specific demand of the place. Most of these places do not allow access or demand a virtual reconstruction.

Online and Global. 24-30 October 2020. edited by B. Slocum, V. Ago, S. Doyle, A. Marcus, M. Yablonina, and M. del Campo. 340-349.
summary	This paper presents the design, control system, and elastic behavior of ELAbot: a robotic bending active textile hybrid (BATH) structure that can self-form and transform. In BATH structures, equilibrium emerges from interaction between tensile (form active) and elastically bent (bending active) elements (Ahlquist and Menges 2013; Lienhard et al. 2012). The integration of a BATH structure with a robotic actuation system that controls global deformations enables the structure to self-deploy and achieve multiple three-dimensional states. Continuous elastic material actuation is embedded within an adaptive cyber-physical network, creating a novel robotic architectural system capable of behaving autonomously. State-of-the-art BATH research demonstrates their structural efficiency, aesthetic qualities, and potential for use in innovative architectural structures (Suzuki and Knippers 2018). Due to the lack of appropriate motor-control strategies that exert dynamic loading deformations safely over time, research in this field has focused predominantly on static structures. Given the complexity of controlling the material behavior of nonlinear kinetic elastic systems at an architectural scale, this research focuses on the development of a cyber-physical design framework where physical elastic behavior is integrated into a computational design process, allowing the control of large deformations. This enables the system to respond to conditions that could be difficult to predict in advance and to adapt to multiple circumstances. Within this framework, control values are computed through continuous negotiation between exteroceptive and interoceptive information, and user/designer interaction.

summary	A rigid spatial structure represents a three-dimensional structural system in which the size of the singular planar elements is very small related to the whole construction. In this paper we will do investigations of quadrilateral patterns and we will propose an analytical method for designing structural rigid folding with quadrilateral patterns following geometrical surfaces of different topology. Our method offers folding structures with four fold lines meeting in one node which allows a simpler solution of join connections and assembling of the whole spatial and structural system. As the physical characteristics of paper can lead to all kinds of wrong conclusions it is necessary to use CAD tools in addition to scale models, where the entire folding element is reconstructed and its geometric characteristics are controlled. This kind of control reflects on the scale model. Models are then adjusted, examined and built to reach certain conclusions that are once more tested in CAD software.
