title	From Digital Heritage Documentation to 3D Virtual Reconstruction and Recreation for Heritage Promotion and Reinterpretation: The Case of the iHeritage Project
source	C+++: Computation, Culture, and Context – Proceedings of the 11th International Conference of the Arab Society for Computation in Architecture, Art and Design (ASCAAD), University of Petra, Amman, Jordan [Hybrid Conference] 7-9 November 2023, pp. 7-23.
summary	In the last two decades, the digital age Information and Communication Technologies (ICT) development and concerns combined with rapid technology have permitted the dissemination of different digital applications (including digital documentation, virtual reality (VR), augmented reality (AR), mixed reality (MR), digital gaming, and holograms etc.) oriented toward past, present and future communication using digital three-dimensional audio-visual content. Today, we must acknowledge that 3D virtual 3D reconstruction and recreation has become an established way to build, understand, reinterpret, and promote Cultural Heritage (CH). The virtual 3D reconstruction world and multimedia industry are often considered potential marketing channels for World Heritage Sites (WHS) and heritage tourism. 3D digital/virtual reconstruction merges and embodies subjectivity in one process, playing an attractive role in heritage tourism destinations and creating image experiences, providing the first enjoyable interpretation and information for most audiences. Based on the EU-funded iHERITAGE project ICT Mediterranean platform for the UNESCO CH, this paper attempts to examine some insights into constructing the optimistic image of heritage promotion and tourism in the context of CH as it flows through both physical and virtual spaces to give a glimpse of the future of virtual reconstruction. It illustrates the development of the concepts and practice, challenges and opportunities, advantages and disadvantages, and the negative and the positive sides of the related issues of only 3D digital reconstructions, and some issues concerning the ethics based on the International Chartres and Conventions mainly in the field of scientific visualisation, such as the London Charter (2009) and Seville Principles (2011). Finally, as a practical dimension, it presents some representative examples of 3D digital/virtual reconstruction of characteristic monuments of the WHS of Nabataean Petra in Jordan for the first time.

title	From Waste to 3D CAD: Framework for Geographical and Temporally Conscious Design Tool
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 979-8-9860805-9-8]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 24-32.
summary	This paper introduces a framework that addresses the limitations of form-first design approaches in contemporary architectural practice, where digital design and comput- er-aided design (CAD) tools often neglect material realities. The framework aims to bridge the gap between form-based and material-centric approaches by proposing a digital design tool that is both geographical and temporally conscious. Outlined in this paper is a proposal for a 3D modeling tool that incorporates information from material, weather, and environmental databases, enabling users to model with location-specific materials that dynamically respond to local environmental factors over time. This integration of material and environmental data empowers designers to consider the temporal dimension of their design decisions, promoting a more environmentally sustainable and contextually respon- sive design practice. The presented framework and pilot tool derived observations and insights from material studies, fabrication experiments, and accelerated weathering tests. These tests involve bio-composites made from agricultural byproducts and food wastes, where the findings are translated into computational simulations for material properties and decay. These insights inform the development of the framework, which seeks to align with the principles of a circular and hyperlocal material economy, countering supply-chain determinism by emphasizing localization, mechanical property variation, and material decay. This paper contributes to the advancement of architectural design and fabrication by bridging the gap between form-based and material-centric approaches, fostering an understanding of materials and their temporal characteristics. The proposed 3D modeling tool promotes sustainable and contextually responsive architectural solutions, advocating for the use of regionally sourced materials.

summary	The growing pressure on natural resources and the increase in demand for construction materials highlight for the construction industry the relevance of opening space for constructive alternatives and materials with less environmental impact. Additive manufacturing has developed through various technologies, materials and scales. 3D printing for construction has grown significantly. An obvious challenge for this technology corresponds to the geometric-constructive solutions that involve other materials for mechanical reinforcement. This research works over the initial development of a construction system based on clay paste reinforced with vegetable ropes, which uses additive manufacturing protocols. Through constructive experiments that integrate string reinforcements into 3d print. The lines of work operate in: Design of architectural elements, Programming of constructive robotic routines, Rheological study of printable clay and fiber pastes and Design of effectors for extrusion of pastes.

title	The Living Room: Knitting as a Strategy to Redefine the Architectural Possibilities of Mycelium Biofabrication in the Built Environment
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 979-8-9860805-9-8]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 208-219.
summary	The Living Room is a mycelium-knit biohybrid architecture that consists of an exposed knitted formwork on the interior and a smooth mycelium plaster on the exterior, creating a monolithic 4-m-diameter, freestanding structure. The aim of The Living Room is to develop a complex architectural form with doubly-curved surfaces; exploiting the unique proper- ties of a composite system that brings together flexible, shaped, 3D knitted formwork, with mycocrete, a bespoke mycelium paste formulated for use with textile scaffolds. Furthermore, The Living Room seeks to demonstrate how bio-textile fabrication can make use of waste materials and by-products from local industries to grow large-scale struc- tures with minimal environmental impact. To achieve these goals, an iterative process was required which integrated physical making at small and large scale, digital modeling, structural analysis, biomaterial experimentation, and knit specification. The design and fabrication process enabled a conceptual design, developed through physical knit prototyping, to be scaled up via digital modeling, to create a large-scale installation with the flexibility to modify the idealized model geometry on site during fabrication. The process is critically examined, and opportunities to improve the form finding and simulation of the knit formwork canopy are identified as key areas for further development.

title	Robotic Incremental Sheet Metal Forming: Waste Management Through Digital Fabrication
source	García Amen, F, Goni Fitipaldo, A L and Armagno Gentile, Á (eds.), Accelerated Landscapes - Proceedings of the XXVII International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2023), Punta del Este, Maldonado, Uruguay, 29 November - 1 December 2023, pp. 657–668
summary	In this investigation, a robotic incremental sheet forming (RISF) process was used as a response to traditional methods of recycling and reusing scrap metal. The methodology was carried out in three stages: digital reconstruction of the waste by 3D scanning, tensile test according to the ASTM E8 standard for the mechanical characterization of the material and the use of a heavy-load robot, KUKA KR180 R2500, for incremental forming. The results obtained in the tensile test indicated that the material maintains its isotropy and reaches 10% elongation. On the other hand, parameters of the incremental forming process showed: the ability of the material to be deformed with a maximum wall angle of 55°; speed rate of 50%; stepdown of 2 mm; and maximum depth of 75 mm. Finally, the process was used for the development of an ornamental surface.

title	Reconfigurable Formwork System for Vision-Informed Conformal Robotic 3D Printing
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. 387–396
doi	https://doi.org/10.52842/conf.ecaade.2023.1.387
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.

title	Bric(k)Colage, CMU Spolia Composites: 3D scanning and printed clay for the recapture of CFD masonry waste
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 159–167
summary	This research investigates the use of LIDAR scanning, physics computational simulations, and ceramic 3D printing to streamline a process for generating a structural masonry bond-work from a given set of discarded pre-fabrication concrete parts. The research capitalizes on an initial set of large scale mockups developed using intuition based stacking of CMU Block detritus, which were in turn LIDAR scanned to produce a series of custom robotically 3d printed ceramic figural bricks to infill the gaps in a mortar based assembly. Following the proof of concept, the researchers explored computational means for simulating various configurations of aggregates using individually scanned broken blocks placed within a physics simulation. The outer boundaries are rigidly defined along with placeholders for desired apertures, and then the scanned detritus is dropped to inform a tight packed bond-work. The final digital aggregate is then run through a grasshopper simulation to derive the linework and print files for a robot to print the negative infill. This paper will discuss the ability for the designer to work within a computational process to produce structural envelope based construction with spoliated detritus towards new varied organizations embraces an aesthetic of visual reuse.

title	Democratizing the Designer’s Toolbox: Adopting free, open-source, and platform-agnostic tools into computational design teaching
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. 41–50
doi	https://doi.org/10.52842/conf.ecaade.2023.1.041
summary	This paper proposes a computational design education approach where students learn to develop their own geometric and logical workflows beyond specific software and platform. The course’s objectives are to familiarize architecture students with computational geometry, foster computational thinking that stays relevant over time, and promote democratized design tools through computation. Over a semester, we taught students to work directly on coordinates or numerical representations by utilizing 3-Dimensional (3D) computer graphics programming rather than learning 3D modeling software that rapidly goes out of style. This paper outlines our teaching methods to introduce the technology stack, design algorithm development, open-source or free tools implementation, and user experience – interface design. This paper also reviews the student’s final projects to deliver interactive web-browser applications for architectural design of varied scales and compares them according to four evaluation parameters. The paper culminates with the project's critical assessment and students' feedback to evaluate our approach and suggest an outlook for future development.

title	Demystifying the patterns of local knowledge: The implicit relation of local music and vernacular architecture
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. 791–800
doi	https://doi.org/10.52842/conf.ecaade.2023.2.791
summary	As the zeitgeist suggests, the development of novel design output using Artificial Neural Networks (ANNs) is becoming an important milestone in the architectural design discourse. With the recent encounter of the computational design realm with the diffusion models, it becomes even easier to generate 2D and 3D design outputs. Yet, the utilization of machine learning tools within design computing domains is confined to generating or classifying visual and encoded data. However, it is critical to evaluate the untapped potentials of machine learning technologies in terms of illuminating the implicit correlations and links underlying distinct concepts and themes across a wide range of technical domains. With the ongoing research project named “Local Intelligence", we hypothesized that the local knowledge of a certain location might be conceptualized as a distributed network to connect different forms of local knowledge. As the first case of the project, we tried to reinstate a commonality between the local music and vernacular architecture, for which we trained generative adversarial network (GAN) models with the visual spectrograms translated from the audio data of the local songs and images of vernacular architectural instances from a defined geography. The two multi-modal GAN models differ in terms of the inherent convolutional layers and data pairing process. The outcomes demonstrated that both GAN models can learn how to depict vernacular architectural features from the rhythmic pattern of the songs in various patterns. Consequently, the implicit relations between music and architecture in the initial findings come one step closer to being demystified. Thus, the process and generative outcomes of the two models are compared and discussed in terms of the legibility of the architectural features, by taking the original vernacular architectural image dataset as the ground truth.

title	Foamwork: Challenges and strategies in using mineral foam 3D printing for a lightweight composite concrete slab
source	International Journal of Architectural Computing 2023, Vol. 21 - no. 3, 388–403
summary	This paper presents an innovative design and fabrication workflow for a lightweight composite slab prototype that combines mineral foam 3D printing (F3DP) and concrete casting. Non-standardized concrete elements that are geometrically optimized for resource efficiency often result in complex shapes that are difficult to manufacture. This paper extends the research in earlier studies, showing that F3DP can address this challenge. F3DP is used to construct 24 stay-in-place formwork elements for a lightweight, resource-efficient ribbed concrete element with a 2 × 1.3 m footprint. This advancement highlights the improved robotic F3DP setup, computational design techniques for geometry and print path generation, and strategies to achieve near-netshape fabrication. The resulting prototype shows how complex geometries that were previously costprohibitive can be produced efficiently. Discussing the findings, challenges, and future improvements offers useful perspectives and supports the development of this resourceful and sustainable construction technique.

title	Digital Structural Design for Natural Composites: A Case Study of Willow-Earth Hybrid Construction
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 979-8-9860805-9-8]. Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 282-292.
summary	As natural resources become increasingly scarce, it becomes crucial to seek solutions that promote circularity and sustainability. Embracing local materials and reinterpreting traditional architectural systems can help align the design of construction systems with these principles. Computational design methods can play a pivotal role in facilitating a transformative approach that supports the development of alternative material systems, their industrialization, and widespread adoption. This paper presents a computational design method for the structural development of a willow-earth composite construction system, aiming to advance the implementation of fully circular and waste-free building techniques through digital construction technologies. The research uses structural principles as a guiding factor for the development of the material system, and employs an integrative co-design approach to manage the reciprocal relationships between structural performance, material system behavior, and fabrication processes. By capitalizing on the advantageous interaction between willow and earth, a material system based on compres- sion-tension dualism is developed. This is achieved through digital studies of mechanical properties and computational analyses that inform the distribution, orientation, and gradation of the materials. The research incorporates feedback loops across multiple disciplines, both digital and analog, enabling a simultaneous consideration of the under- lying correlations. The research showcases the potential to expand the design possibilities for structures constructed with earth and willow composite materials. Through a distinc- tive digital workflow, it presents new avenues for sustainable and circular construction methods. The outcomes are illustrated through digital studies and a full-scale research demonstrator, providing tangible evidence of the research's advancements.

title	Design across multi-scale datasets by developing a novel approach to 3DGANs
source	International Journal of Architectural Computing 2023, Vol. 21 - no. 2, 358–373
summary	The development of Generative Adversarial Networks (GANs) has accelerated the research of Artificial Intelligence (AI) in architecture as a generative tool. However, since their initial invention, many versions have been developed that only focus on 2D image datasets for training and images as output. The current state of 3DGAN research has yielded promising results. However, these contributions focus primarily on building mass, extrusion of 2D plans, or the overall shape of objects. In comparison, our newly developed 3DGAN approach, using fully spatial building datasets, demonstrates that unprecedented interconnections across different scales are possible resulting in unconventional spatial configurations. Unlike a traditional design process, based on analyzing only a few precedents (typology) according to the task, by collaborating with the machine we can draw on a significantly wider variety of buildings across multiple typologies. In addition, the dataset was extended beyond the scale of complete buildings and involved building components that define space. Thus, our results achieve a high spatial diversity. A detailed analysis of the results also revealed new hybrid architectural elements illustrating that the machine continued the interconnections of scale since elements were not explicitly part of the dataset, becoming a true design collaborator.

title	COVID-19 and the City: An Analysis of the Correlation between Urban and Social Factors and COVID-19 in Fortaleza, Brazil
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 45–52
summary	The COVID-19 pandemic has been the biggest sanitary crisis humanity has ever faced, the virus has contaminated 662.717.929 people worldwide and killed 6.701.270 people. However, these numbers were not distributed equally at international, national or urban scale. In Fortaleza, Brazil, city studied in this paper, data from 2021 and 2022 epidemiologic reports suggest a contamination pattern that starts in neighborhoods with higher Human Development Index (HDI) and then goes to lower HDI neighborhoods, however, throughout all of this cycle, low HDI neighborhoods tend to have a higher lethality rate. These facts raised the hypothesis that those neighborhoods have specific urban and social factors that affect the capacity to respond and prevent COVID-19. The main objective of this paper is to identify the correlation of some urban and social factors with COVID-19 data. To achieve that, the authors selected seven variables (access to water rate, literacy rate, waste collection rate, population density, access to electric energy rate, sanitation rate and average monthly income) to correlate with four COVID- 19 indicators (total number of cases, total number of deaths, contamination rate and lethality rate). For this, it was chosen to apply Spearman’s correlation coefficient and for the calculation the statistical software Jamovi was used. The results show that the literacy rate, the access to electric energy rate and average monthly income have a positive correlation with the contamination rate, however these same variables have a negative correlation with the lethality rate.

doi	https://doi.org/10.52842/conf.caadria.2023.1.383
summary	This paper reflects on the notion of hyper-reality through the creation of ‘Self-Compass’, an immersive mixed reality art installation. By merging the physical with overlayed digital 3D content, this study proposes a view of current notions of the metaverse as an extension of reality rather than a digitized replacement of it. This was demonstrated by augmenting a modular installation with an immersive digital counterpart through an augmented reality (AR) application accessible through mobile devices. ‘Self-compass’ combines a timber structure and a digital AR overlay into a radial configuration that framed eight views, revealing an historical connection beyond the immediate context, and inviting reflections on the relationship between oneself and place. The AR overlay merges meaning with data, allowing one to rethink the physical through the digital, and providing awareness of our impact on place across time. The paper discusses and evaluates applied methods of merging digital and physical objects through a mixed reality (MR) installation. It expands on current workflows through the development of an AR mobile application and examines simultaneous localization and mapping (SLAM) techniques, essential in the alignment of digital content within real-world environments. The paper concludes by illustrating the potential applications and impact of AR technologies within design practices by augmenting the physical and revealing a new hyper-reality.

title	Evolution of Modelling in Architecture: A Framework for the categorisation and evaluation of digital models in Architectural Design

doi	https://doi.org/10.52842/conf.ecaade.2023.2.811
summary	Apart from being an integral part of the architectural design process, modelling is becoming central to architecture as well as to neighbouring fields. The technologies and tools applicable for the generation, development and coordination of models are growing rapidly. In one single project, a wide range of models is used which poses challenges in practice in terms of establishing a systematic way to utilise those modelling techniques and access their potential benefits. Aiming to enhancing the effectiveness and efficiency of the various modelling methods, this paper establishes a framework for the different types of models where the models are categorised and evaluated based on different criteria. To achieve this, a critical review of the literature related to the history of modelling in architecture and the emergence of the different methods of modelling is conducted. Beyond classical, CAD-based 3D models, the framework identifies four categories of modelling methods: performative modelling, algorithmic modelling, parametric modelling, and BIM. Each category is evaluated based on the generation and modification process, model entity and model function. Subsequently, the paradigm shifts associated with each modelling method are identified and discussed.

summary	The intent of this research is to study potential improvements and optimizations in the context of robotic fabrication paired with Augmented Reality (AR), leveraging the technology in the fabrication of the individual part, as well as guiding the larger assembly process. AR applications within the Architecture, Engineering, and Construction (AEC) industry have seen constant research and development as designers, fabricators, and contractors seek methods to reduce errors, minimize waste, and optimize efficiency to lower costs (Chi, Kang, and Wang 2013). Recent advancements have made the technology very accessible and feasible for use in the field, as demonstrated by seminal projects such as the Steampunk Pavilion in Tallinn, Estonia (Jahn, Newnham, and Berg 2022). These types of projects typically improve manual craft processes. They often provide projective guidelines, and make possible complex geometries that would otherwise be painstakingly slow to complete and require decades of artisanal experience (Jahn et al. 2019). Building upon a previously developed robotic tube bending workflow, our research implements a custom AR interface to streamline the bending process for multiple, large, complex parts with many bends, providing a pre-visualization of the expected fabrication process for safety and part-verification purposes. We demonstrate the utility of this AR overlay in the part fabrication setting and in an inadvertent, human-robot, collaborative process when parts push the fabrication method past its limits. The AR technology is also used to facilitate the assembly process of a spatial installation exploring a unique aesthetic with subtle bends, loops, knots, bundles, and weaves utilizing a rigid tube material.

title	Weaving Tectonics: Algorithmically Optimised Robotic FRP Weaving of Large Scale Planar Forms
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_39
summary	Steel reinforced concrete is a widely used material for constructing large spanning planar building elements due to its strength, durability, and low cost, but its environmental impact, long fabrication time, and relatively low structural performance demonstrate the need for innovation. To address these issues, this study proposes a novel design methodology and fabrication method that integrates robotic Fibre Reinforced Polymer (FRP) woven reinforcement that is optimized using a Multi-Weight Bi-directional Evolutionary Structural Optimization (MW-BESO) algorithm. The optimized FRP reinforcement is then cast in epoxy resin to produce the large scale planar building element. The methodology is evaluated through a Tabletop prototype and other small-scale rapid prototypes, which demonstrate the successes, challenges, and limitations of this approach. The study outlines the material and methodological testing conducted to assess the effectiveness of using the MW-BESO algorithm with robotic FRP weaving and describes the workflow of transforming the resulting 3D MW-BESO geometry into a 2D robotic winding path for fabrication. The research shows that this methodology has the potential to reduce the environmental impact, stimulate innovative design solutions, and streamline the fabrication of large scale building elements, providing a promising avenue for the development of sustainable and efficient construction techniques.

title	Extending Visuospatial Analysis in Design Computing: An Exploration With a Novel GPU-Based Algorithm and Form-Based Codes

summary	This paper responds to a gap observed between the contemporary capacity for calculation and analysis of visibility of built environment features, such as buildings, in digital urban and architectural computational research models and the functionality of off-the-shelf software tools available to professionals. The research investigates the potential of visibility analysis to be embedded and extended within computational-based workflows of software tools to better meet urban design and planning industry needs. We introduce a novel method for visibility calculation that exposes output data for further analysis within a computational workflow and implement it in a game development engine used by software tool providers. Based in our engagement with a local government authority, we then use that method to demonstrate a workflow in the context of form-based building codes in which the visual impact of a building is considered rather than prescriptive limits on dimensions and use. Our results indicate the novel method has substantial performance improvements compared to an alternative mode of visibility calculation and that software providers could more thoroughly integrate and extend visibility analysis to meet industry needs.
