summary	The past decade has seen a growing interest in the use of textiles in architecture, driven by advancements in digital knitting technology. However, while digital knitting machines have enabled the creation of 3D-shaped textiles, they still face limitations in terms of handling complex topologies, output scale, and material thickness. This study proposes crochet as an alternative to knitting in large-scale applications due to its ability to create seamless 3D shells. Although there have been significant advances in the computation of crochet instructions, placing it within the context of additive manufacturing, a digital fabrication method for volumetric crochet is still lacking. This paper offers a comprehensive overview of the recent history of computational tools utilized in fabricating continuous yarned 3D textiles together with an in-depth comparison to reveal the significant differences between knitting and crochet. It then proceeds to identify the relevant design attributes for a novel technology by analyzing hand gestures and toolpaths. Finally, the paper presents a novel digital fabrication device designed for large-scale crochet frameworks, which highlights the considerable advantages of crochet over other related fabrication methods. The proposed robotic device employs patented technology, which enables unprecedented fabrication capabilities in the field and opens new prospects for incorporating large-scale textiles in architecture.

summary	Learning in virtual reality (VR) is always happening in a certain digital space. Inspired by memory techniques such as Method of Loci AKA Memory Palace, we propose to use a VR 3D space as a form of Memory Palace which would enhance the learning process by attaching new knowledge to spatial experience. Aim is to create multi-sensory experiences and help people to form deeper memory traces of learned topics. To achieve desired efficiency we need easily remembered space, which would help to create rich episodic memory. It is also important for the environment not to disturb and attract too much attention from the learning topic. To find this thin line, we tested memorability of VR space through experiments with 9 different environments each deferring in the level of abstraction and detail of the scenes. Subjects walked through the environment in VR and were instructed to perform various memory tasks. Results show that an environment with a middle level of abstraction and detail was easiest to remember, since it achieved a certain level of newness while being well comprehensible.

title	Mobile Augmented Reality for Aided Manual Assembly of Compressed Earth Block Dwellings
doi	https://doi.org/10.52842/conf.ecaade.2023.2.019
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 2, Graz, 20-22 September 2023, pp. 19–28
summary	This paper investigates how augmented reality (AR) can instruct and assist in assembling an earthen structure consisting of a limited set of geometrically different interlocking blocks. By adapting a visual-inertial object tracking software, to the assembly process of a mortarless, compressed earth block (CEB) dome, the construction site no longer needs physical templates and manuals. This enables the builders to have real-time tracking with visual feedback to actively adjust according to the optical guidance during the course of assembly. Two identical dome structures are built with the same set of earth blocks, one with AR and one without. The results show that using AR can significantly improve construction efficiency for complex, dry-stacked structures as it acts as assembly guidance and provides insight into the limits of the tracking tolerances. Further, this paper discusses the limitations and challenges and can provide an outlook for further research scaling up the production to construct a habitable dwelling. Starting with just a pile of dirt and a mobile phone, the demonstrator exhibits the compatibility of local, sustainable materials and digital, efficient processes.

title	Spatially Graded Modeling: An Integrated Workflow For 3D Concrete Printing
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. 361–372
summary	While 3D concrete printing (3DCP) has surged in popularity, methods to harness its design potential remain largely underdeveloped. Existing design-to-manufacture workflows most commonly restrict the design to the overall geometry and a set of print parameters that may fall outside of the scope of the designer. This study presents a novel approach to integrate design and manufacturing by an integrated design-to-manufacture workflow that allows the gradation of the wall thickness along the printed part, which can be independently manipulated using established computer graphic techniques like texture projection and mesh coloring. The effectiveness of this workflow is demonstrated through the fabrication of a test body featuring a customized surface pattern. This approach aims to extend the design scope for 3DCP, enabling the addition and editing of surface patterns without geometry or code manipulation.

title	Democratizing the Designer’s Toolbox: Adopting free, open-source, and platform-agnostic tools into computational design teaching
doi	https://doi.org/10.52842/conf.ecaade.2023.1.041
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
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	Enhancing Cultural Heritage Digitalization and Visitor Engagement Through LiDAR Scanning and Gamification
doi	https://doi.org/10.52842/conf.caadria.2024.2.283
source	Nicole Gardner, Christiane M. Herr, Likai Wang, Hirano Toshiki, Sumbul Ahmad Khan (eds.), ACCELERATED DESIGN - Proceedings of the 29th CAADRIA Conference, Singapore, 20-26 April 2024, Volume 2, pp. 283–292
summary	Cultural heritage assets are valuable, providing important information about humanity's past and conveying it to the future. Unfortunately, conventional documentation is insufficient to preserve them for the next generations. Furthermore, increasing visitor interaction with these assets and raising awareness has been one of the challenges in this field. In this paper, we will examine how mobile LiDAR (Laser Detection and Ranging) technology can be used to precisely scan and document historical sites and how it can be combined with gamification elements to provide visitors with better experiences. It is also important that the texture taken in mobile laser scanning can be used to better visualize 3D mesh models of the scanned objects, so the fastest application that produces 3D models is selected. The study area is Syedra Ancient City in Alanya / Turkey, where the research and excavation process has continued since 2015 and the restoration projects started in 2023. Future work includes the creation of experiences to provide a basis for gamification and revitalizing the story of the heritage for the visitors through digital storytelling and AR (Augmented Reality). Preserving historical sites while providing visitors with a more in-depth, vivid and enjoyable experience are important facts for enhancing cultural heritage and passing it on to future generations.

title	Visualizing Dynamic and Highly Interactive Lighting
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 119–128
summary	As a defining factor in shaping people’s experience in architectural spaces, lighting is realistically visualized via a plethora of rendering options in CAD and BIM solutions. However, their outputs are usually static or limited to basic changes. Thus, they may not satisfactorily visualize many dynamic and interactive lighting scenarios, such as energy-saving smart windows and lights, engaging street illumination, and entertainment setups. With the increasing automation of human-building interaction (HBI), visualizing such interactions empowers researchers and students who are interested in experimenting with customized lighting setups. Moving in this direction, this paper presents the lighting features of Tames, an open-source Unity toolkit developed by the author that visualizes dynamic and interactive elements in virtual environments without a need for programming. With Tames, the designers can navigate and interact with the design from the perspective of an occupant with the lighting and other elements in real-time manually or automatically. The workflow and capabilities of Tames are demonstrated by its application in the context of concert hall project designed by a student. This author argues that the availability and user-friendliness of this tool will contribute to architectural pedagogy and research. It allows students and researchers to visualize a wider variety of interactive designs and cases easier and, as an enabling tool, it may encourage them to explore and experiment with dynamic and interactive lighting.

title	A Human-Centric Approach to a Design-to-Fabrication Process: A Case of Homeless Housing Design in Melbourne, Australia
doi	https://doi.org/10.52842/conf.caadria.2023.2.461
source	Immanuel Koh, Dagmar Reinhardt, Mohammed Makki, Mona Khakhar, Nic Bao (eds.), HUMAN-CENTRIC - Proceedings of the 28th CAADRIA Conference, Ahmedabad, 18-24 March 2023, pp. 461–470
summary	Recent advancements in computer-aided design (CAD) and computer-aided manufacturing (CAM) have influenced architects to practice more purposeful design processes. However, most previous research have focused on innovating CAD and CAM technologies and less on how to automate the specific needs of users into design-to-fabrication processes. Therefore, this study applies a human-centric design approach to examine how designers can leverage specific and dynamic individual needs in digital design processes to optimise designing of housing. Using research through design, we tested our user-design-fabrication framework with dynamic needs of homeless individuals and 3D printing construction technologies, to design and prototype homeless housing solutions in Melbourne, Australia. This research demonstrates that specific and dynamic occupant needs are leveraged by designer's increased knowledge of digital design processes for 1) greater manipulation of basic software and machines and 2) provision of more individualised homeless housing design solutions. This suggests that there is a need for design researchers to further investigate the role of designers in such digital design processes working with homeless individuals, to foresee the current move in industry for more client-oriented and individualised homeless housing design solutions.

title	Three-Dimensional Realtime Air Quality Mapping using Astronomical algorithms on Urban Environments
doi	https://doi.org/10.52842/conf.ecaade.2023.2.811
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 2, Graz, 20-22 September 2023, pp. 811–820
summary	The OMS estimates that over 7 million people die every year of complications attributed to atmospheric pollution. Air quality has degraded progressively and dramatically in urban environments over the last couple of decades, being a current concern in most metropolitan areas, and the focus of public policy as well as public/private scientific innovation for better diagnostics and better solutions. At SIC we are developing a method for 3D mapping the sources, affected locations, density, motion, translation, and potential composition of polluted air masses in close to real-time. We do this by leveraging a multidisciplinary approach that encompasses urban and architectural simulation with data science and astronomical techniques, producing a data visualization that enables novel research in air quality, urban policy, private investment, sustainability efforts, and smart transportation. Our approach, Sit-C, combines satellite remote sensing of air masses and atmospheric conditions, with data obtained from traffic and urban surveillance cameras deployed throughout the city of Santiago, in Chile. These cameras, oftentimes open to public access, are usually placed linearly along main avenues, or scattered around urban milestones, providing walk-though perspectives and locally situated POVs to observe the city, analog to series of cross-sections through urban areas. Satellite sensing provides a large-scale plan view, allowing for precise location of specific conditions across a region. This collaboration between architects, designers, engineers, and meteorologists, from Chile and Finland, combines digital design, data science, and remote sensing techniques to study air quality. We study suspended particulate matter (SPM) and other molecules, and its spatial behavior over time, through light-occlusion analysis, producing a three-dimensional map of the air over a city.

summary	Afforestation in drylands is an active ecosystem restoration strategy shown to increase ecosystem services in these regions, which are highly prone to land degradation. Nevertheless, seedling recruitment is difficult in such projects due to various biotic and abiotic stresses. This paper proposes a methodology for providing tree seedlings in drylands with 3D-printed soil-based bioclimatic envelopes. The workflow suggests key aspects in transforming locally sourced soils to 3D printable, bioclimatically performable materials. Essential robotic tooling aspects and processing parameters are proposed. In addition, ways to embed site-specific data to algorithmically conceive a customized envelope according to the tree species are suggested.

title	Assessment of Correlative Digital Drawing Features in the Design Processes of Unstructured Creativity
doi	https://doi.org/10.52842/conf.ecaade.2023.1.231

summary	This research critically challenges the conventional perception of drawings as mere technical blueprints and delves into the intricate integration of design ideation, abstraction, and speculation with geometrical manipulations and semantic labelling. By focusing on unconventional architectural design studio experiments at the undergraduate level, the study aims to explore the role of creativity in speculative drawing. It adopts a 3- dimensional design thinking process that transcends the rigid constraints of traditional drawings and embraces the fluidity of representational norms. Furthermore, the paper elucidates on the pedagogical aspects of the design studio, including the unstructured creativity inherent in the design process. The methodology employed in this study is exemplified through different stages of the design studio, incorporating a variety of representations such as 2D, 2.5D, and 3D,encompassing scalar, geometric, and material transfigurations. To assess the outcomes of the studio, the research utilises correlation diagrams that establish connections between digital drawing features at different stages and the unstructured creativity manifested in the final design. These scatter and correlation diagrams capture the syntactic relationships between the objects within digital drawings. The findings of this study reveals insight on the nuanced interplay between intuitive, reflective, and retrospective aspects of unstructured creativity during the design ideation process. By unraveling the intricate role of digital design tools and methods this research contributes to a deeper understanding of of how design ideation is generated and manifested through the dynamic interplay of the modulating compounds of drawing objects. It highlights the significance of meaningful, conceptual, and speculative representations that directly relate to the creation of buildable forms and architectural spaces. Through its critical insights, this study paves the way for advancements in the field of CAAD and offers valuable perspective for architectural education and practice.

summary	This paper investigates the potential of Text-to-Image AI in assisting the ideation phase in architectural design and education. The study proposes a structured workflow and tests it with first-year architecture students. It aims to create a comprehensive design vocabulary by using AI-generated images as primary design references and incorporating them into a modelling workflow. The paper implements a process combining specific vocabulary extraction, image generation, 2D to 3D translation, and spatial composition within a six weeklong design course. The findings suggest that such a process can enhance the ideation phase by generating new and diverse design inspirations, improve spatial understanding through the exploration of various design elements, and provide students with a targeted visual vocabulary that helps define design intention and streamlines the modelling process.

title	Customising Urban Joy: Urban Planning Mechanisms for the Mass - Customisation of Cities, through the Quantifiable Nature of Joy Using Geo-tagged Social Media Data
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. 31–42
summary	The paper examines citizen participation in a digitally-driven society and the disparity between desired and existing cities. It emphasises the need to transform cities into adaptable environments that respond to the needs of residents. Traditional top-down urban planning often fails to match the flexible nature of digitised urban residents. To address this, an agent-based model is employed, evaluating urban environments based on individual sentiment derived from social media API. The study case of Wittenberge, Germany, showcases the methodology, including the creation of a 3D digital twin using open data sources and generating agents with unique personalities from social media keywords. These agents' "life satisfaction score" reflects their ability to fulfil daily needs and preferences within a 20-minute walking radius.

title	Demystifying the patterns of local knowledge: The implicit relation of local music and vernacular architecture
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	Airlements: A Lightweight and Insulating Monolithic Wall System made with Foam 3D Printing
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 54-60.
summary	oam 3D printing investigates additive manufacturing of porous construction materials for novel lightweight and insulating building components. It leverages the opportunities of automated, moldless fabrication that can reduce waste, hazardous labor, and costs for material-efficient, geometrically-optimized, and previously cost-prohibitive structures. Moreover, the thermal resistance of porous materials addresses the insulation perfor- mance of building elements and can help to reduce the operational energy consumption of buildings. Airlements is the largest demonstrator produced in this research using cement-free, geopolymer-based mineral foams made from industrial waste. The two-meter-tall struc- ture composed of four stacked segments explores the advantages of lightweight manual assembly for monolithic non-structural walls. A finish made from cement-free spray plaster completes the facade system. This paper presents the advancements in the robotic 3D-printing setup, the demonstrator design and fabrication, and discusses the advantages and challenges of this novel method. In light of the gaining popularity of large-scale 3D printing, particularly with concrete, this study contributes to the body of work with alternative materials that can improve the sustainability and building physics performance of innovative building elements.

summary	This paper investigates the potential integration of blockchain and distributed ledger technologies with Additive Manufacturing in the context of architectural design and fabrication. The study aims to identify knowledge gaps, explore the affinity between these technologies, and challenge the current architecture production paradigm. Through a comprehensive state-of-the-art review and analysis of academic papers and industrial case studies, we identified emerging themes and gaps in the literature. We also examined the misalignment of incentives among key participants of the proposed systems. Our findings highlighted the relevance of blockchain technology in additive manufacturing, but also revealed significant challenges and misalignments in incentives among stakeholders. We argue that further research and experimentation are necessary to fully understand the technical feasibility and impact of integrating these technologies in architectural design and fabrication.

title	Cavity Shell: Sequential Cast-in-Place Method to Create Compression-Only Structures with Ultra-Thin Additively Manufactured Formwork Assemblies

summary	A compression-only structure's impressive strength-to-weight ratio allows it to span large spaces using significantly less material. However, prefabricated masonry or concrete components used to construct compression-only structures are prone to damage during handling and transportation, and contribute to CO2 emissions. Additionally, assembling these components requires heavy falsework, which results in material wastage and increased construction costs. This research paper presents an alternative approach to constructing compression-only structures by introducing a new, in-situ construction approach based on coupling 3D-printed, ultra-lightweight plastic formwork and sequential casting of the formwork in compression on site. This is achieved through developing: 1) a new construction method based on the assembly of lightweight, 3D printed plastic form- work in compression-only form, which is then sequentially cast with concrete in place; 2) an integrative formwork system informed by structural and casting logics (i.e., flowability, the height of the casting point in relation to hydrostatic pressure, placement of formwork interface in alignment to internal forces in the structure; and 3) a parametric model for translating force-form diagram to integrative formwork. To verify this research method, Cavity Shell, a 1:1 scale compression-only table leg structure, measuring 1.4 meters in radius and 0.8 meters in height, was designed and built (Figure 1). This ultra-lightweight formwork took less than 48 hours to assemble, and was sequentially cast by two people. This research demonstrates the potential to rethink the construction of compression-only structures by minimizing the material used, and improving economic and environmental efficiency in their construction life cycle.

title	Mixed Reality Interactive Representations for the Assembly of a Custom Timber Tower
doi	https://doi.org/10.52842/conf.ecaade.2023.2.751

summary	In recent years, many projects have emerged testing the use of augmented reality (AR) and mixed reality (MR) systems in the custom design and fabrication of architectural projects at a variety of scales using digital and analog tools. This paper presents a series of MR systems for key modes of interactive representations in the assembly process of a custom timber tower, intending to expand an area of research on the use of MR as a critical medium for architectural representation in design customization. The series of MR systems were developed to assist and expedite the physical assembly of customized timber parts and connections for the large-scale tower with a small team of students and carpenters. The MR systems are built as interactive representations of the 3D digital design model, allowing the user to see connections in real-time on physical materials in order to perform collaborative preparation and assembly tasks with analog tools. Each MR system relied on a single user, wearing a HoloLens 2, to use hand gestures to place and interact with 3D Rhino model representations of the tower and individual parts overlaid in the physical context at 1:1 scale. The MR systems deployed as interactive 3D representations were evaluated at three key stages in the material preparation and assembly processes. The project tested the use of MR systems created for a series of tasks that enabled the fast assembly of the tower, which is almost 10 meters high. The outlook explores the perspective of how MR systems augment modes of architectural representation through human interaction, collaboration, and accessibility (also for non-expert users), using digital and analog tools, and how these systems provide greater agency for customization and variety in design and building.
