title	'GHShot': a collaborative and distributed visual version control for Grasshopper parametric programming
source	Sousa, JP, Xavier, JP and Castro Henriques, G (eds.), Architecture in the Age of the 4th Industrial Revolution - Proceedings of the 37th eCAADe and 23rd SIGraDi Conference - Volume 3, University of Porto, Porto, Portugal, 11-13 September 2019, pp. 35-44

summary	When working with parametric models, architects typically focus on using rather structuring them (Woodbury, 2010). As a result, increasing design complexity typically means a convoluted parametric model, amplifying known problems: 'hard to understand, modify, share and reuse' (Smith 2007; Davis 2011). This practice is in contrast with conventional software-programming where programmers are known to meticulously document and structure their code with versioning tool. In this paper, we argue that versioning tools could help to manage parametric modelling complexity, as it has been showing with software counterparts. Four key features of version control: committing, differentiating, branching, and merging, and how they could be implemented in a parametric design practice are discussed. Initial user test sessions with 5 student designers using GHShot Grasshopper version control plugin (Cristie and Joyce 2018, 2017) revealed that the plugin is useful to record and overview design progression, share model, and provide a fallback mechanism.

title	A Critical Evaluation of Two Contextualised Digital Heritage Workshops - Descriptions, reflections and future directions
source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 189-198

summary	In the following paper, a description, a comparison, a series of reflections, and future directions of two successful Contextualized Digital Heritage Workshops (CDHW) will be presented. The workshops have been organized during the eCAADe and CAADRIA conferences. The importance of architectural heritage as an expression of a local history and identity in a world that is more and more globalised is evident. Multidisciplinary and interdisciplinary approaches, together with the use of digital technologies open new opportunities in the comprehension, documentation, analysis, reuse and dissemination of architectural heritage. The main concept behind a CDHW is to connect the event (and its wide variety of participants) to a specific local context in a multidisciplinary way. The paper defines and proposes a methodology to critically evaluate the two workshops and their individual aspects in order to identify and investigate ideas that can be explored during future CDHWs.

summary	Decisions taken at early stages of building design have a significant effect on the planning steps for the entire lifetime of the project as well as the performance of the building throughout its lifecycle (MacLeamy 2004). Building Information Modelling (BIM) could bring forward and enhance the planning and decision-making processes by enabling the direct reuse of data hold by the model for diverse analysis and simulation tasks (Borrmann et al. 2015). The architect today besides a couple of simplified simulation tools almost exclusively uses his know-how for evaluating and comparing design variants in the early stages of design. This paper focuses on finding new ways to facilitate the use of analytical and simulation tools during the important early phases of conceptual building design, where the models are partially incomplete. The necessary enrichment and proper detailing of the design model could be achieved by means of dialogue-based interaction concepts with analytical and simulation tools through adaptive detailing strategies. This concept is explained using an example scenario for design process. A generic description of the aimed dialog-based interface to various simulation tools will also be discussed in this paper using an example scenario.

summary	Contained in this years paper proceedings are an unbiased mixed of the precise/imprecise and the computationally faithful/unfaithful. The juxtaposition of this seeming contradictory research and/or projects paints a picture of a broadening computational discourse at the intersection of art, science and technology. The presented research mediates physical, digital, virtual and mixed realities, bridges scales from the singular material compounds to the complex conglomerations associated with the urban environment, and all the while pushing against the limits of design both on Earth and beyond. This year’s conference calls into question how we within the disciplines of architecture and design as well as those outside view the role of computation, production and advanced technologies such as robotics and artificial intelligence within architecture, design and the built environment.

summary	This paper examines a novel, integrated and collaborative approach to design and fabrication, enabled through Mixed Reality. In a bespoke fabrication process, the design is controlled and altered by users in holographic space, through a custom, multi-modal interface. Users input is live-streamed and channeled to 3D modelling environment,on-demand robotic fabrication and AR-guided assembly. The Holographic Interface is aimed at promoting man-machine collaboration. A bespoke pipeline translates hand gestures and audio into CAD and numeric fabrication. This enables non-professional participants engage with a plethora of novel technology. The feasibility of Mixed Reality for architectural workflow was tested through an interactive installation for the makeCity Berlin 2018 festival. Participants experienced with on-demand design, fabrication an AR-guided assembly. This article will discuss the technical measures taken as well as the potential in using Holographic Interfaces for collaborative design and on-site fabrication.Please write your abstract here by clicking this paragraph.

summary	The integration of technology into the design process has enabled us to communicate through various modes of virtuality, while more traditional face-to-face collaborations are becoming less frequent, specifically for large scale companies. Both modes of communication have benefits and disadvantages - virtual communication enables us to connect over large distances, however can often lead to miscommunication, while face-to-face communication builds stronger relationship, however may be problematic for geographically dispersed teams. Mixed Reality is argued to be a hybrid of face-to-face and virtual communication, and is yet to be integrated into the building design process. Despite its current limitations, such as field of view, Mixed Reality is an effective tool that generates high levels of nonverbal and verbal communication, and encourages a high and equal level of participation in comparison to virtual and face-to-face communication. Being a powerful communication tool for complex visualisations, it would be best implemented in the later stages of the building design process where teams can present designs to clients or where multiple designers can collaborate over final details.

title	Cyclopean Cannibalism. A method for recycling rubble
source	ACADIA // 2018: Recalibration. On imprecisionand infidelity. [Proceedings of the 38th Annual Conference of the Association for Computer Aided Design in Architecture (ACADIA) ISBN 978-0-692-17729-7] Mexico City, Mexico 18-20 October, 2018, pp. 404-413

summary	Each year, the United States discards 375 million tons of concrete construction debris to landfills (U.S. EPA 2016), but this is a new paradigm. Past civilizations cannibalized their constructions to produce new architectures (Hopkins 2005). This paper interrogates one cannibalistic methodology from the past known as cyclopean masonry in order to translate this valuable method into a contemporary digital procedure. The work contextualizes the techniques of this method and situates them into procedural recipes which can be applied in contemporary construction. A full-scale prototype is produced utilizing the described method; demolition debris is gathered, scanned, and processed through an algorithmic workflow. Each rubble unit is then minimally carved by a robotic arm and set to compose a new architecture from discarded rubble debris. The prototype merges ancient construction thinking with digital design and fabrication methodologies. It poses material cannibalism as a means of combating excessive construction waste generation.

title	Understanding the AR-VR Based Architectural Design Workflow among Selected Danish Architecture Practices
source	Pak, B, Wurzer, G and Stouffs, R (eds.), Co-creating the Future: Inclusion in and through Design - Proceedings of the 40th Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2022) - Volume 1, Ghent, 13-16 September 2022, pp. 381–388

summary	Virtual reality (VR) and augmented reality (AR) have been proposed to be additional architectural design mediums for at least 25 years (Dagit, 1993). Despite rapid technical and technological development, it has not been adopted into architectural design practices as compared to academia and research. Surveys from the American Institute of Architects (AIA) and Royal Institutes of British Architects (RIBA) demonstrate the state of architectural practices; 72% of architects and 65% of architects respectively are not using any kind of virtual, augmented, or mixed reality in their practices(RIBA and Microsoft, 2018; Hampson, 2020). In this paper, the authors investigate the state of practices, issues, challenges, and opportunities of the utilization of virtual, augmented, and mixed realities in six architectural practices in the Danish context. Three of the practices are large architectural practices, one medium-sized practice specializing in institutional, healthcare and cultural architecture, and one firm designing private family houses, kindergartens, daycares and places for people with disability and, one experimental design studio. All these practices have used VR/AR in their projects to various degrees. In recent years Danish architectural practices have been involved in various VR/AR-based exhibitions, demonstrations, and tool developments to promote the usage of the same in design practice. Through a set of qualitative interviews with personnel from key architectural practices, the authors would like to demonstrate the present state of practices. The investigation explores the usage of VR and AR in Danish architecture practices by identifying challenges and opportunities regarding skill levels, architectural typology, use cases, toolchains, and workflow and shows similarities and differences between traditional and VR-based design processes. The main findings show how VR/AR-based visualization helps architects to perceive spatiality and also ushers creativity through immersion and overlays.

title	Do Training Bikes Dream of Electric Cities ?

summary	Virtual reality (VR), Augmented Reality (AR) and Mixed Reality is making the headlines in the newspapers and magazines today. But unlike 25 years ago when the first VR rage started with the first Cave Automatic Virtual Environments (CAVE) infrastructures VR is now a technique that is available at very low costs.Especially the recent advances and developments in low cost VR hardware mainly the Head mounted displays (HMD), in particular those that use mobile phones but also the PC based systems like the Oculus Rift and the HTC Vive together with recent software developments allow this change. Naturally this is based on the interest of the Gaming Industry and the big players in the smartphone industry. But at the moment there are nearly no tools for architects available within these systems. In our point of view there is the big potential that these technologies can give new opportunities to architects and designers to use VR and AR as part of their design toolbox and not only as a presentation tool. For us this is the most important aspect. In our projects we therefore try to develop a workflow that can be easily used even without programming and scripting skills.

title	Programming Material Intelligence Using Food Waste Deposition to Trigger Automatic Three-Dimensional Formation Response in Bioplastics
source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 271-278
doi	https://doi.org/10.52842/conf.ecaade.2018.2.271
summary	Bioplastics are by their very nature parametric materials, programmable through the selection of constituent components and the ratios in which they appear, and as such present significant potential as architectural building materials for reasons beyond sustainability and biodegradability. This paper presents a system through which rigid three-dimensional doubly curved hyperbolic paraboloid shapes are automatically formed from two-dimensional sheet casts by harnessing the inherent flexibility and expressiveness of bioplastics. The system uses a gelatin-based bioplastic supplemented with granular organic matter from food waste in conjunction with a split-frame casting system that enables the self-formation of three-dimensional geometries by directing the force of the bioplastic's uniform contraction as it dries. By adjusting the food waste added to the bioplastic, its properties can be tuned according to formal and performative needs; here, dehydrated granulated orange peel and dehydrated spent espresso-ground coffee are used both to impart their inherent characteristics and also to influence the degree of curvature of the resulting bioplastic surfaces. Multi-material casts incorporating both orange peel bioplastic and coffee grounds bioplastic are shown to exert a greater influence over the degree of curvature than either bioplastic alone, and skeletonized panels are shown to exhibit the same behavior as their solid counterparts. Potential developments of the technology so as to gain greater control of the curvature performance, particularly in the direction of computer-controlled additive manufacturing, are considered, as is the potential of application in architectural scale.

title	Point Cloud Stream on Spatial Mixed Reality - Toward Telepresence in Architectural Field
source	Kepczynska-Walczak, A, Bialkowski, S (eds.), Computing for a better tomorrow - Proceedings of the 36th eCAADe Conference - Volume 2, Lodz University of Technology, Lodz, Poland, 19-21 September 2018, pp. 727-734

summary	In remote meetings that involve the study of buildings and cities, sharing three-dimensional (3D) virtual spatial of buildings and cities is just as necessary as sharing the appearances and voices of meeting participants. Because of this, system development and pilot projects have attempted to share 3D virtual models via the internet in real-time but is still insufficient compared with face-to-face meeting. Therefore, this research explores the applicability of a spatial mixed reality (MR) system that displays point cloud streams to realize 3D remote meeting in architecture and urban fields. MR is a new technology that enables 3D presentations of various information, combining the physical and virtual worlds. One MR method is telepresence, which is expected to give people a way to communicate remotely as if face to face in a realistic way. We first developed a MR system named PcsMR (Point cloud stream on mixed reality) to display point cloud streams. The PcsMR system's operation consists of generating and transferring a point cloud stream and then rendering a point cloud stream using MR. The PcsMR acquired the point cloud stream in real-time using Kinect for Windows v2 and transferred it to Microsoft HoloLens, which uses optical see-through MR. Then we constructed two prototypes based on PcsMR and carried out pilot projects. Through observing the experiments, application possibilities for architecture and urban fields are found in meetings and communications that share real-time 3D objects and include the movement of remote participants and objects. The proposed method was evaluated feasible and effective.

summary	This work exposes the possible composition of a system composed of "crowd-working" of static, inert, flexible architecture elements, similar or identical entities, the "tesserae" and the integration with the link generated with Artificial Intelligence artifacts, a complex adaptive system, as a first experimental step to developments of Nanomaterials and systems that respond to the construction of the projective thought of the architectural envelope. The research responds to a general strategy of theoretical revision, with inductive and mixed methods. The exploration work examines the relative space within the idea of reason and the social function of architecture.

The result would be indicative to egocentric spatial analysis research, and reveal potentials as a reference point for a new architectural design tool.

doi	https://doi.org/10.52842/conf.acadia.2018.088
summary	The construction industry’s reliance on two-dimensional documentation results in inefficiency, inconsistency, waste, human error, and increased cost, and limits architectural experimentation with novel form, structure, material or fabrication approaches. We describe a software platform that enables designers to create interactive holographic instructions that translate design models into intelligent processes rather than static drawings. A prototypical project to design and construct a pavilion from bent mild steel tube illustrates the use of this software to develop applications assisting with the design, fabrication, assembly and analysis of the structure. We further demonstrate that fabrication within mixed reality environments can enable unskilled construction teams to assemble complex structures in short time frames and with minimal errors, and outline possibilities for further improvements.

summary	Applying the method of "Land-Use Mix" (Amindabari et al. (2013)) and Focusing on changes in highly mixed land use areas within an extensive survey area and detailed analytical unit, the analysis in this study revealed some trends of distribution of mixed land use areas and their declining patterns in the eastern part of Saitama Prefecture, Japan. For example, among the changing land use patterns of Highly-Mixed-Points-as-of-1994, the pattern that a decreasing mixture index was associated with increasing residential land and decreasing commercial land occurred most often, and the points that changed with that pattern accounted for about 32% of all the Highly Mixed Points, and about 51% of the decrease in mixture index points.

summary	In the late 1960s the architect Nicholas Negroponte introduced that the physical environment could exhibit reflexive and simulated behaviours, an idea that has since been widely explored. Despite of this wider interest, there is not, however, a systematic approach to understanding architectural responsiveness in the digital age. This paper aims to provide a formal way to facilitate designing smart and interactive artificiality in the built environment. This paper presents a conceptual framework, through exploratory studies on recent architecture, highlighting four key behaviours: (1) tangible interaction, (2) embodied response, (3) ambient simulation, and (4) mixed reality. In addition, two essential enablers, collectiveness and immersion, are proposed to enhance these key behaviours. This framework can be used as a tool to systematically identify and characterise the responsiveness of "responsive architecture". The creative mixtures of the key behaviours will contribute to the development of unique responsive environments.

summary	Fabricating complex curvature in concrete panel typically required unique one-off formwork which is usually computer numerically controlled (CNC) milled, generating enormous waste as a by-product. What if, we can produce complex curvature in concrete with minimal or no immediate construction waste? This paper presents a novel machine designed by a team of architects and engineer to eliminate waste in concrete casting. Using a hyperbolic paraboloid geometric model, the machine produces variable shape using a single mould design reducing waste and cost to the casting process. The paper discussed the design framework of the system and its fabrication workflow. The outcome is digitally scanned and verified to satisfy industry standard. The paper concludes by reviewing the application of the system and highlighting the need for future research into digital fabrication and design that is less wasteful and waste conscious to better the process of constructing our built environment.

summary	'Sistema Nervi' (the Nervi System) invented by Pier Luigi Nervi greatly economised the production of complex concrete forms optimised in both material usage and structurally. However it did not translate well into other contexts due to labour and material considerations (Leslie, 2018). This paper explores novel methodologies of producing optimised floor slabs and concrete structures, using digital fabrication techniques, focusing on both labour economisation and sustainability principles. A module from the Australia Square lobby slab has been used as the set geometry and was reproduced using differing techniques of fabrication for a comparative study. The study was conducted at scale (1:20). The viability for production at full scale (1:1) for manufacturing is discussed. The assessment criteria for the tests are divided into four categories: Cost, Time, Performance, and Sustainability. 3D printing of PLA plastic and ceramic clay extrusion printing has been used to produce removable or degradable formworks. These technologies have been selected due to their current market availability and associated costs. This study hopes to introduce improved methodologies for producing optimized concrete forms, as well as the sustainability potentials of a degradable formwork such as ceramic clay. Both systems were ultimately able to produce workable formworks for optimised shapes and showed promise for reducing labour involved as well as presenting with material sustainability for discussion.

title	Subtractive digital fabrication with actual robot and virtual material using a MARI platform
source	International Journal of Architectural Computing vol. 16 - no. 4, 281-294
summary	This article presents a project-based research study using a new hybrid augmented reality platform called the Mixed Architectural Robotic Interface. Using the Mixed Architectural Robotic Interface as a mixture of different software and hardware platforms, ranging from design/modeling software, simulation engine, and an augmented reality application, the designer would be able to evaluate the possibilities/limitations of the fabrication, in real time and as part of the design. This method advances designer’s understanding of the fabrication equipment as an input for the design decision-making process. This article demonstrates the potential of a virtual/actual hybridized platform as a new medium to design, simulate, and evaluate, in order to enhance the digital design and fabrication. Introducing the possibility of real-time communication between the digital design software and the fabrication platforms as well as the augmented reality simulation of the fabrication process, the Mixed Architectural Robotic Interface enables designers to test the fabrication process with the fabrication equipment in the early stages of the design process. This method makes it possible to move beyond the traditional limitations of machines pursuing “un-expected creativity,” without any additional time or cost for the process. Using the virtual material for fabrication, the Mixed Architectural Robotic Interface reduces the time and cost of having multiple iterations and encourages the hands-on experimental use of the fabrication tool (in this article robotic/computer numeric control milling) not only as a production tool but also as a design study tool.

summary	This paper presents a mixed-method research design investigation that integrates a Hybrid Digital-Analog Software-Hardware protocol referred to as the No Keyboard, No Mouse (NK-NM) platform. The NK-NM process uses both theoretical and applied research mechanisms to measure its influence on architectural design decision-making, knowledge exchange, student learning, aesthetics, and user experience in the context of an undergraduate architectural design studio. Observing a recognized gap in the current digital architectural design environments this paper details how the NK-NM protocol bridges this gap through an instructed hierarchical design process, customizable physical interface, and iterative simulation-based feedback loop.
