title	AR + DESIGN: An Experiment in Remote Teaching and Practice using Augmented Reality for Interactive Brick-based Structure Design
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. 950-962.
summary	Due to the COVID-19 breakout and its epidemic prevention restrictions, remote communication has become one of the critical solutions that almost every industry is exploring in this post-epidemic era. Likewise, architectural practitioners also look at remote possibilities for current design methods. This paper presents a unique experimental research using augmented reality (AR) immersion technology for interactive brick-based structure design to explore a remote design method overlayed on the spatial context in the architectural draft visualisation and modification stages. It discusses the teaching process and practice outcomes from an online workshop, which is conceptualised to allow participants to learn, master, and apply the proposed remote design method in AR for brick-based structures. For this online workshop, we enrich the current parametric design method to an AR-assisted way for remote possibilities. The employed workflow was driven by an instant connection between 3D modelling software (Rhinoceros 3D), the parametric design plugin (Grasshopper), and the AR immersion plugin (Fologram). This experiment explored and validated the possibility of remote teaching and practice in architectural design education for post-epidemic era requirements.

summary	Interactive architecture is a concept that focuses on self-governing behaviour through engagements with the environment and users. This paper introduces designing and fabricating a responsive building skin made of several small unit cells, replacing centralized and hierarchical architectural systems with open and extensible distributed networks. The proposed concept involves modular structures with adaptable building components, allowing greater flexibility, self-government, and resilience than centralized systems. A cone-shaped hexagonal electro-mechanical unit functions as a three-dimensional aperture, opening and closing mechanically using custom-made linear actuators. The aggregation of units forms a dynamic surface that can be installed inside, outside, or on both sides of a transparent wall. The interactivity of the aggregated system was simulated and calibrated using the grasshopper parametric virtual modelling plugin for Rhinoceros. A prototype of five modules was constructed and tested for thirty days, revealing the highest susceptibility to damage in the components.

title	Stereotomic BIM. A plugin for designing low carbon architecture
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. 1253–1262
summary	This paper focuses on the development of a BIM (Building Information Modeling) tool for stereotomic design, aiming to create a bridge between academic research and practical implementation of stereotomy in the construction sector. The creation of a stereotomic BIM tool enhances the use of compressive materials within funicular shapes to minimize reliance on carbon-intensive steel-reinforced concrete slabs. The proposed BIM tool enables architects to design and visualize stereotomic systems, addressing challenges such as architectural specificity and technological expertise. Architects can work from initial shape concepts to the precise geometric definition of elements, benefiting from the interactive adjustment of subdivisions and considering materialization and assembly specifics. This approach aligns with the Industry 4.0 paradigm, contributing to both sustainable development goals and the evolution of construction practices.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
doi	https://doi.org/https://doi.org/10.1007/978-981-99-8405-3_44
source	Proceedings of the 2023 DigitalFUTURES The 5st International Conference on Computational Design and Robotic Fabrication (CDRF 2023)
summary	A research team at Florida International University Robotics and Digital Fabrication Lab has developed a novel method for 3d-printing curved open grid core sandwich structures using a thermoplastic extruder mounted on a robotic arm. This print-on-print additive manufacturing (AM) method relies on the 3d modeling software Rhinoceros and its parametric software plugin Grasshopper with Kuka-Parametric Robotic Control (Kuka-PRC) to convert NURBS surfaces into multi-bias additive manufacturing (MBAM) toolpaths. While several high-profile projects including the University of Stuttgart ICD/ITKE Research Pavilions 2014–15 and 2016–17, ETH-Digital Building Technologies project Levis Ergon Chair 2018, and 3D printed chair using Robotic Hybrid Manufacturing at Institute of Advanced Architecture of Catalonia (IAAC) 2019, have previously demonstrated the feasibility of 3d printing with either MBAM or sandwich structures, this method for printing Compound-Curved Sandwich Structures with Robotic MBAM combines these methods offering the possibility to significantly reduce the weight of spanning or cantilevered surfaces by incorporating the structural logic of open grid-core sandwiches with MBAM toolpath printing. Often built with fiber reinforced plastics (FRP), sandwich structures are a common solution for thin wall construction of compound curved surfaces that require a high strength-to-weight ratio with applications including aerospace, wind energy, marine, automotive, transportation infrastructure, architecture, furniture, and sports equipment manufacturing. Typical practices for producing sandwich structures are labor intensive, involving a multi-stage process including (1) the design and fabrication of a mould, (2) the application of a surface substrate such as FRP, (3) the manual application of a light-weight grid-core material, and (4) application of a second surface substrate to complete the sandwich. There are several shortcomings to this moulded manufacturing method that affect both the formal outcome and the manufacturing process: moulds are often costly and labor intensive to build, formal geometric freedom is limited by the minimum draft angles required for successful removal from the mould, and customization and refinement of product lines can be limited by the need for moulds. While the most common material for this construction method is FRP, our proof-of-concept experiments relied on low-cost thermoplastic using a specially configured pellet extruder. While the method proved feasible for small representative examples there remain significant challenges to the successful deployment of this manufacturing method at larger scales that can only be addressed with additional research. The digital workflow includes the following steps: (1) Create a 3D digital model of the base surface in Rhino, (2) Generate toolpaths for laminar printing in Grasshopper by converting surfaces into lists of oriented points, (3) Generate the structural grid-core using the same process, (4) Orient the robot to align in the direction of the substructure geometric planes, (5) Print the grid core using MBAM toolpaths, (6) Repeat step 1 and 2 for printing the outer surface with appropriate adjustments to the extruder orientation. During the design and printing process, we encountered several challenges including selecting geometry suitable for testing, extruder orientation, calibration of the hot end and extrusion/movement speeds, and deviation between the computer model and the physical object on the build platen. Physical models varied from their digital counterparts by several millimeters due to material deformation in the extrusion and cooling process. Real-time deviation verification studies will likely improve the workflow in future studies.

title	Creative Impact of an Event-Driven Visual Scripting Tool
doi	https://doi.org/10.52842/conf.caadria.2023.2.331
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. 331–340
summary	Computational design is gaining global prominence. With the increase in demand for technologically capable designers, we find more designers understanding computers better, learning programming languages and adapting technologies to fit their needs. This has led to multidisciplinary communities forming around visual scripting tools (VSTs) like Grasshopper3D, Dynamo, etc. These communities consist of many users from creative fields who find it easier to learn a visual scripting language than a programming language. However, function-driven programming and various quirks of these tools delimit their application to a closed spectrum of use-cases. This further limits the users’ capabilities and forces many to hack their way around basic programming language paradigms like loops, event handling, etc. VSTs seem to promote a creative affinity to programming, while also making it more approachable and accessible. To understand the creative impact of a more powerful VST, this paper outlines the development and use of an agnostic event-driven VST - one based on MVVM software architecture and linked list data structures, written entirely in C# (WPF) with minimal dependencies. With features like plugin extensibility and interoperability with 3D software (e.g., Rhinoceros), this new tool is built to aid creative programming driven by events and data. This implies enhanced capabilities for the user and enables interactive computation of data in real-time. User experience inferences are derived from diverse user studies, with a focus on students and professionals in the design and AEC industries. Various parameters and test scenarios are used to objectively assess the impact of enabling event-driven programming for creative use.

title	Urban Fabric Generation: A comparative analysis of multiple vector field methods
doi	https://doi.org/10.52842/conf.ecaade.2023.1.721
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. 721–730
summary	This paper provides a comparative analysis of vector field methods for automatically generating urban fabric geometries and introduces the Rhino/Grasshopper plugin UrbanFab which implements these methods. Automated generation of urban design is a growing area of research addressing the complex challenge of building sustainable and economically viable cities. Within this research area vector fields are used to generate non-uniform urban fabric geometries. Similar to simulation of magnetic fields or moving fluids, vector field algorithms can be adapted to simulate urban sites, resolving complex site constraints and generating geometry used in the design of roads, land parcels or buildings. Vector field methods for urban fabric generation, however, are not well represented in computational tools serving urban designers, or in description of algorithms and evaluations in computational urban design literature. To address these challenges, this paper describes multiple urban vector field algorithms, with accompanying streamline visualization and evaluation methods. A comparative analysis of the results generated by these methods provides a means for designers to make informed decisions on which method is appropriate to their requirements and supports discussion of future work in urban fabric generation.

summary	After experiencing the Covid-19 pandemic, remote communication became one of the key issues in almost every field and discourse. Digital fabrication is no exception, and architects hope to seek a user-friendly way for human-machine interactions. This paper presents experimental research using Augmented Reality (AR) for robotic remote programming. The research tries to develop a unique pipeline and workflow which allows users from different locations to program robots and communicate with machines through AR. A sample workflow has been tested as a series of simple brick assemblies in an online workshop with remote participants. The pipeline allows all users to be able to remotely program and control a robot in AR. For this workshop, we transform the robotic coding method from the traditional computer science way to the plugin-oriented AR visual programming way in Grasshopper. As for the physical outcomes, participants all assembled brick-based structures successfully by programming and operating the robotic arm in AR remotely at the end. Associating the interaction in AR with the robotic arm and programming it with interactive visual input methods will make it easier for architectural practitioners to simulate and control industrial robots for complex structure assembly.

title	Towards a Tool Kit for Membrane Tensegrity Shells: Exploring the Relationship Between Struts and Geometry
doi	https://doi.org/10.52842/conf.caadria.2023.2.261
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. 261–270
summary	Our paper demonstrates a computational design workflow that creates and maps optimal 2D strut layouts based on input 3D shell geometries that function as membrane tensegrity shell (MTS) structures suitable for human occupancy. This workflow links conformal mapping, structural analysis, and optimisation algorithms to iterate through a series of strut layout parameters. From these layouts, we generate digital MTS models that, under structural loading, closely match their respective target models. We validate this workflow across five different geometries and this has produced low average local deviations that range between 47 to 65 mm, proving that our workflow is viable for non-standardised wide-spanning (8.0m) shell geometries with openings.

Denver. 26-28 October 2023. edited by A. Crawford, N. Diniz, R. Beckett, J. Vanucchi, M. Swackhamer 64-71
summary	This paper introduces a research project of a kinetic apparatus that translates collected air quality data to users. The kinetic mechanical skeleton is embedded with processors and electronics, and constantly changes its form according to air quality data collected online via a web crawler. By translating invisible environmental conditions, such as air quality data into morphological, colorful, and acoustic changes for the device, the participants can be aware of the phenomenon of air pollution in real time. The interac- tions between participants' movements and the changes of the device imply how human behaviors can affect the state of the atmosphere. As a result, the device evokes public awareness and participation in environmental issues through tangible experiences. This research aims to explore a new kind of responsive architecture that acts as a medium between invisible environments and inhabitants.

title	Wave-edge Modeling Method for Segmented Timber Plate Shell Structures: A computational tool for optimizing the bonding area of CLT joints
doi	https://doi.org/10.52842/conf.ecaade.2023.1.301
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. 301–310
summary	The paper presents an algorithmic modeling tool for segmented timber shell structures made of glued wave-edge CLT plates. The goal is to provide a larger bonding area and thereby higher adhesive strength between plates, especially where a higher tension-resistant capacity is required. In addition to a number of contemporary research for exploring stereotomic modules, the inspiration is taken from the long history of the traditional glued finger joints in carpentry where they are used for providing higher interlocking capacity and adhesive strength. The structural performance of regular and glued finger joints is directly proportional to the bonding area between adjoining elements where they are interlocked and glued. Hence, expanding the shared faces would intrinsically magnify the structural performance of the glued finger joints. The paper presents the modeling method of a material-efficient, grain-informed, and structurally-optimized wedge edge joint system for the multi-shaped shell structures where the wave pattern is chosen for generating smoother fabrication toolpaths compared to any sharp-cornered pattern. The algorithm developed by the authors can efficiently maximize the glue bond by optimizing the wave-edge properties dynamically with respect to the geometric design, material system, and structural analysis within a feedback loop. The wave-edge properties directly affect the material waste and fabrication time and cost; therefore, the production parameters could be directly considered and controlled within the design process. The algorithm is able to produce the structural data model for the direct RFEM structural analysis, and fabrication data for automated production of multitude elements. The paper argues the application possibilities and limitations of the joint system for multi-shaped timber plate shells made of a multitude of geometrically-differentiated timber plates.

title	Four-Dimensional Printing on Textiles Evaluating Digital File-to-Fabrication Workflows for Self-Forming Composite Shell Structures
doi	https://doi.org/10.52842/conf.ecaade.2023.1.491
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. 491–498
summary	This design-led research investigates the development of self-forming wearable composite structures by printing embossed patterns out of flexible filament on pre-stretched textiles and releasing the stress after the printing has been completed, whereby time becomes the fourth dimension of the printing process. In particular, the study presents and compares three methods of ‘file-to-fabrication’ techniques for generating self-forming textile shell structures: The first is based on modified geometrical patterns in relation to curvature analysis, the second on printed patterns related to their stress line simulation and the third on an analysis of the anisotropic shrinking behaviour of stripe patterns. The findings emphasize the advantages and challenges of each method as well as present a comparative table chart highlighting the relationship between material properties, pattern geometry and the formal vocabulary of the composite shells.

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	Campusim: An Integrated Parametric BIM for Campus Design Simulation and Optimization

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. 471–480
summary	Although simulation models have been recently employed to model and examine pedestrian behavior in urban areas, comparable research has not been pursued in campus environments despite their importance as a critical area of inquiry. Those models' paucity and methodological limitations suggest investigating new research and design strategies to objectively assess and describe how the qualities of campus spaces and zones influence human behavior and, hence, predict the patterns of users' interaction and space usage. Those patterns and their impact on health have been pointed out as critical to the relationship among public space and quality of life due to Covid-19. There is an urgent need to develop decision support tools that would support interactive design processes and enhance the quality of open space design in terms of sense of space, place-making, and user interaction. To that goal, this study has proposed the integrated parametric BIM-based campus life simulation "CampuSIM" as a method for parametrization of the qualities of pedestrian campus zones and spaces. The study proposed the use of multi-objective optimization methods to fulfill various campus quantifiable and non-quantifiable design objectives. The significance of the proposed tool will result from its potential application in a wide range of complex, dynamic pedestrian behavior scenarios such as flows, social simulations, and design.

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.

A preliminary study is done on the risk level of displacement based on historical data of displacement and vulnerable communities are then mapped out. The potential of using a game as a platform for discussion, evaluation and consensus-building is investigated in this paper. The game permits players to choose different roles to play and make design decisions by placing various building blocks in the multiplayer environment. Game scores such as equitability and profitability are tracked to encourage discussions and negotiations. Game session consisting of participants with relevant profiles has been conducted and results of which will be shared in this paper.

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.

summary	This paper aims to show an academic experiment with the verification of spatial use through user experience and collaborative virtual simulation of an urban microarchitecture: Experiential Point. An immersive and interdisciplinary experience is proposed with sixty-five students in the career of Architecture and Industrial Design, organizing them in teams to complete a proposal of an Urban Microarchitecture in seven weeks. Through a collaborative design agreement with international companies and universities, this work combines a strategy focused on user experience and extended reality as a resource within a hybrid design automation workshop. The design problem focuses on urban equipment with an emphasis on social aspects and the citizen needs. With the results of the "Experiential Point" an interactive and collaborative design strategy is generated implementing the ecology of knowledge using all the senses of the student and the user to experience the spatial quality and efficiency of the proposal.
