title	Computational Analysis of Architectural Visual Space Along Walking Path by Using Virtual Reality Display
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 709–718

summary	This study evaluated architectural space quantitatively based on ambulatory vision. In this paper, we propose a computational analysis method of a visual space along a walking path by using a virtual reality display. A display image of our system is shown from the first-person perspective. We consider the perspective to be the visual field of the users. To convert the perspective into a visual field, we take advantage of depth buffer data, which can specify how far a pixel of an object is on the perspective. To analyse a visual space by a sequence of visual field, we quantify the geometric characteristics based on isovist theory. A virtual reality display, which employs a wide range view angle and a head-tracking system, also enables us to analyse the relation between the visual field and head motion.

title	A Visual Analytics Framework for Large Transportation Datasets
source	Rethinking Comprehensive Design: Speculative Counterculture, Proceedings of the 19th International Conference on Computer-Aided Architectural Design Research in Asia (CAADRIA 2014) / Kyoto 14-16 May 2014, pp. 223–232

summary	The advancement of sensor technologies makes it possible to collect large amounts of dynamic urban data. On the other hand, how to store, process, and analyze collected urban data to make them useful becomes a new challenge. To address this issue, this paper proposes a visual analytics framework, which is applied to transportation data to manage and extract information for urban studies. More specifically, the proposed framework has three components: (1) a geographic information system (GIS) based pipeline providing basic data processing functions; (2) a spatial network analysis that is integrated into the pipeline for extracting spatial structure of urban movement; (3) interactive operations allowing the user to explore and view the output data sets at different levels of details. Taking Singapore as a case study area, we use a sample data set from the automatic smart card fare collection system as an input to our prototype tool. The result shows the feasibility of proposed framework and analysis method. To summarize, our work shows the potential of geospatial based visual analytics tools in using ‘big’ data for urban analysis.

title	Modeling on Outdoor Thermal Comfort in Traditional Residential Neighborhoods in Beijing Based on GAN
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_23
summary	With the support of new urban science and technology, the bottom-up and human-centered space quality research has become the key to delicacy urban governance, of which the Universal Thermal Climate Index (UTCI) have a severe influence. However, in the studies of actual UTCI, datasets are mostly obtained from on-site measurement data or simulation data, which is costly and ineffective. So, how to efficiently and rapidly conduct a large-scale and fine-grained outdoor environmental comfort evaluation based on the outdoor environment is the problem to be solved in this study. Compared to the conventional qualitative analysis methods, the rapidly developing algorithm-supported data acquisition and machine learning modelling are more efficient and accurate. Goodfellow proposed Generative Adversarial Nets (GANs) in 2014, which can successfully be applied to image generation with insufficient training data. In this paper, we propose an approach based on a generative adversarial network (GAN) to predict UTCI in traditional blocks. 36000 data samples were obtained from the simulations, to train a pix2pix model based on the TensorFlow framework. After more than 300 thousand iterations, the model gradually converges, where the loss of the function gradually decreases with the increase of the number of iterations. Overall, the model has been able to understand the overall semantic information behind the UTCI graphs to a high degree. Study in this paper deeply integrates the method of data augmentation based on GAN and machine learning modeling, which can be integrated into the workflow of detailed urban design and sustainable construction in the future.

title	Context-Aware Multi-Agent Systems: Negotiating Intensive Fields
source	SIGraDi 2014 [Proceedings of the 18th Conference of the Iberoamerican Society of Digital Graphics - ISBN: 978-9974-99-655-7] Uruguay- Montevideo 12,13,14 November 2014, pp. 138-143
summary	This paper presents research into a technique using context-aware agent based branching L-systems to design explore an urban development scheme in an area of peripheral Mexico City. The design research demonstrates a viable approach to engaging design with specific agent driven objectives that negotiate across highly differentiated fields of data sets. These data sets are the driving force behind this technique, to generate highly differentiated infrastructure and urban networks that are simulated to be autonomous and emergent. The described system consists of simulated robotic autonomous agents that sample and negotiate across data from the site, and react to differences in order to deploy an irrigation network for a polluted and highly saline former lake-bed east of Mexico City.

summary	Architecture took an evolutionary context over time, where designers were interested in finding pragmatic spontaneous appropriate solutions and met the needs of people in urban and architectural spaces. Whereas, in modern architecture an intense and varied competition happens between architects through various currents of thoughts , schools and movements, however, that creativity was the ultimate goal , and a the same time we find that every architect distinguishes himself individually or collectively through tools of architectural expression and design representation adopting a school of thought, using , for example, the leaves of various sizes and diverse technical drawing tools to accurately show that he can be read by professionals or craftsmen outside the geographical scope to which it belongs .With the rapid technological development which accompanied the digital craft in the contemporary world , The digital craft summed up time, distance and tools , so they gave the concept more appropriate accuracy , as virtualization has become the most effective tool for Architecture To reach the ideal and typical results at the practical level, or pure research. At the level of residential design and on the grounds that housing plays an important role in the government policies and given that housing is a basic unit common to all urban communities on earth , the use of different programs to show its typicality in two dimensions or in the third dimension - for example, using software "AutoCAD " " 3D Max " , " ArchiCAD " ... etc. - gave virtualisation smart, creative and beautiful forms which lead to better understand the used /or to be used residential spaces, and thus the conclusion that the life system of dwelling under design or under study , as can specifically recognize spatial structure in housing design - using digital software applying "Space Syntax" for example - in the shadow of slowly growing digital and creative development with the help of high-speed computers . the morphological structure of the dwelling is considered to be the most important contemporary residential designs Investigation through which the researcher in this area aims to understand the various behavioral relations and social structures within the projected residential area, using Space Syntax techniques. Through the structural morphology of dwellings can be inferred quality networks, levels of connectivity and depth and places of openness or closure within the dwelling under study, or under design. How, then, have intelligently contributed this digital craft to the perception of those spatial fixtures ? The aim of this research is to apply an appropriate program in the field of vernacular residential design and notably Space syntax which relate to the understanding and analysis of spatial structures, and also demonstrate its role at the morphological and spatial structure aspects, and prove how effective it helps to understand the social logic of domestic space through social individual/collective relationships and behaviors projected on the spatial configurations of dwellings. The answer to the issue raised above and at the methodological aspect, the study discussed the application of space syntax techniques on the subject. The findings tend to prove the efficiency by comparing samples of Berber vernacular domestic spaces from the Mzab, the Aures and Kabilya in Algeria, and has also led to ascertain the intelligibility of space syntax techniques in reading the differences between the behaviors in domestic spaces in different areas of the sample through long periods of time .

summary	The conference logo is a bird’s eye view of spiral stairs that join and separate – an homage to the famous double spiral staircase in Graz, a tourist attraction of this city and a must-see for any architecturally minded visitor. Carved out of limestone, the medieval construction of the original is a daring feat of masonry as well as a symbolic gesture. The design speaks of separation and reconciliation: The paths of two people that climb the double spiral stairs separate and then meet again at each platform. The relationship between architectural design and the growing digital repertoire of tools and possibilities seems to undergo similar cycles of attraction and rejection: enthusiasm about digital innovations – whether in Virtual Reality, Augmented Reality, Energy Design, Robotic Fabrication, the many Dimensions of BIM or, as right now, in AI and Machine Learning – is typically followed by a certain disillusionment and a realization that the promises were somewhat overblown. But a turn away from these digital innovations can only be temporary. In our call for papers we refer to the first and second ‘digital turns’, a term Mario Carpo coined. Yes, it’s a bit of a pun, but you could indeed see these digital turns in our logo as well. Carpo would probably agree that design and the digital have become inseparably intertwined. While they may be circling in different directions, an innovative rejoinder is always just around the corner. The theme of the conference asked participants to re-consider the relationship between Design and the Digital. The notion of a cycle is already present in the syllable “re”. Indeed, 20 years earlier, in 2003, we held an ECAADE conference in Graz simply under the title “Digital Design” and our re-using – or is it re-cycling? – the theme can be seen as the completion of one of those cycles described above: One level up, we meet again, we’ve come full circle. The question of the relationship between Design and the Digital is still in flux, still worthy of renewed consideration. There is a historical notion implicit in the theme. To reconsider something, one needs to take a step back, to look into the past as well as into the future. Indeed, at this conference we wanted to take a longer view, something not done often enough in the fast-paced world of digital technology. Carefully considering one’s past can be a source of inspiration. In fact, the double spiral stair that inspired our conference logo also inspired many architects through the ages. Konrad Wachsmann, for example, is said to have come up with his famous Grapevine assembly system based on this double spiral stair and its intricate joinery. More recently, Rem Koolhaas deemed the double spiral staircase in Graz important enough to include a detailed model of it in his “elements of architecture” exhibition at the Venice Biennale in 2014. Our interpretation of the stair is a typically digital one, you might say. First of all: it’s a rendering of a virtual model; it only exists inside a computer. Secondly, this virtual model isn’t true to the original. Instead, it does what the digital has made so easy to do: it exaggerates. Where the original has just two spiral stairs that separate and join, our model consists of countless stairs that are joined in this way. We see only a part of the model, but the stairs appear to continue in all directions. The implication is of an endless field of spiral stairs. As the 3D model was generated with a parametric script, it would be very easy to change all parameters of it – including the number of stairs that make it up. Everyone at this conference is familiar with the concept of parametric design: it makes generating models of seemingly endless amounts of connected spiral stairs really easy. Although, of course, if we’re too literal about the term ‘endless’, generating our stair model will eventually crash even the most advanced computers. We know that, too. – That's another truth about the Digital: it makes a promise of infinity, which, in the end, it can’t keep. And even if it could: what’s the point of just adding more of the same: more variations, more options, more possible ways to get lost? Doesn’t the original double spiral staircase contain all those derivatives already? Don’t we know that ‘more’ isn’t necessarily better? In the original double spiral stair the happy end is guaranteed: the lovers’ paths meet at the top as well as when they exit the building. Therefore, the stair is also colloquially known as the Busserlstiege (the kissing stair) or the Versöhnungsstiege (reconciliation stair). In our digitally enhanced version, this outcome is no longer clear: we can choose between multiple directions at each level and we risk losing sight of the one we were with. This is also emblematic of our field of research. eCAADe was founded to promote “good practice and sharing information in relation to the use of computers in research and education in architecture and related professions” (see ecaade.org). That may have seemed a straightforward proposition forty years ago, when the association was founded. A look at the breadth and depth of research topics presented and discussed at this conference (and as a consequence in this book, for which you’re reading the editorial) shows how the field has developed over these forty years. There are sessions on Digital Design Education, on Digital Fabrication, on Virtual Reality, on Virtual Heritage, on Generative Design and Machine Learning, on Digital Cities, on Simulation and Digital Twins, on BIM, on Sustainability, on Circular Design, on Design Theory and on Digital Design Experimentations. We hope you will find what you’re looking for in this book and at the conference – and maybe even more than that: surprising turns and happy encounters between Design and the Digital.

title	Binocular Disparity and Depth Cue of Luminance Contrast

summary	Luminance contrast has been identified as an effective depth cue through perceptual studies using digital images generated by the integrated technologies of physically based lighting simulation and perceptually based tone mapping. However, the prior established framework utilizes a single camera viewpoint, failing to address the binocular vision of the human visual system. In this study, the computational framework is extended to incorporate 3-dimensional (3D) stereo display technology. Psychophysical experiments were conducted to investigate the depth effect of luminance contrast on the experimental scenes presented on conventional and stereo displays. The objective of this study was twofold: first, to investigate the effect of luminance contrast on depth perception, considering binocular vision; second, to further advance the visual realism of the computer-generated environment to reflect the perceptual reality of static pictorial and binocular disparity cues.

title	Integrated Generative Technique for Interactive Design of Brickworks

summary	Bricks have been used in the construction industry as a building medium for millennia. Distinct patterns of bricks depict the unique aesthetic intentions found in Roman, Gothic and Islamic architecture. In contemporary practice, the use of digital tools in design has enabled methodologies for creating new forms in architecture. CAD and BIM systems provide new opportunities for designers to create parametric objects for building form generation. In masonry design, there exists an inherent contradiction between traditional patterns in brick design, which are formal and prescribed, and the potential for new patterns generated using design scripting. In addition, current tools do not provide interactive techniques for the design of brickwork patterns that can manage constant changes parametrically, to inform and influence design process, by providing design feedback on the constructive and structural aspects of the proposed brick pattern and geometry. This research looks into the parametric techniques that can be applied to create different kinds of patterns on brick walls. It discusses a methodology for an interactive brickwork design within generative techniques. By integrating data between two computational platforms – the first based on image analysis and the second on parametric modeling, we demonstrate a methodology and application that can generate interactive arbitrary patterns and map it to the brick wall in real-time.

summary	This design research reimagines the architectural detail in a postdigital framework and proposes digital methods to work upon discrete tectonics. Drawing upon Marco Frascari's writing The Tell-the-Tale Detail, the study aims to reimagine tectonic thinking for focused attention after the digital turn. Today, computational tools are powerful enough to perform operations more similar to physical tools than in the earlier digital era. These tools create a "digital materiality," where architects can manipulate digital information in parallel and overlapping ways to physical corollaries. (Abrons and Fure, 2018) To date, work in this area has focused on materiality specifically. This project reinterprets tectonics using texture map editing and point cloud information, particularly reconceptualizing jointing using images. Smartphone-based 3D digital scanning was used to captured details from a series of Carlo Scarpa's influential works, isolating these details from their physical sites and focusing attention upon individual tectonic moments. As digital scans, these details problematize the rhetoric of smoothness and seamlessness prevalent in digital architecture as they are discretely construed loci yet composed of digital meshes. (Jones 2014) Once removed from their contexts, reconnecting the digital scans into compositions of "compound details" necessitated a series of new mechanisms for constructing and construing not native to the material world. Using Photoshop editing of texture-mapped images, digital texturing of meshes, and interpretation of the initial material constructions, new joints within and between these the digital scanned details were created to reframe the original detail for the post-digital.

summary	The paper will present one specific aspect of the PhD research called Cibersemiótica e Processos de Projeto: Metodologia em Revisão, funded by FAPESP, which in turn is linked to the Nomads.usp research group of the University of São Paulo. The paper discusses aspects of digital design processes within an approach on social collaboration with digital mediation, from concepts based on Actor Network Theory, developed by the French Philosopher Bruno Latour, Swarm Behaviour, which is observed in nature, as well as the Multi-Agent Systems. The paper aims to examine collaborative procedures and hybrid design methods involving several actors or players, trying to redefine the possibilities of conception in Architecture with a bottom-up approach, considering the concept of game applied to digital design processes.

title	Comparison between Genetic Optimization and Heuristic Methods for Prioritizing Infrastructure Rehabilitation Programs
source	Digital Crafting [7th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2014 / ISBN 978-603-90142-5-6], Jeddah (Kingdom of Saudi Arabia), 31 March - 3 April 2014, pp. 175-182
summary	In recent years, infrastructure rehabilitation has been in the focus of attention in North America and around the world. A large percentage of existing infrastructure assets is deteriorating due to harsh environmental conditions, insufficient capacity, and age. Due to stringent budget limits, however, asset management systems become important to assess the life cycle performance of various assets, and accordingly prioritize the assets for rehabilitation purposes. While many asset management systems have been introduced in the literature, almost no studies have compared the effectiveness of their asset prioritization methods. This paper presents an extensive comparison between heuristic and optimization methods for prioritizing large-scale rehabilitation programs, under budget constraints. The paper first introduces different life cycle cost analysis (LCCA) formulations for three case studies obtained from the literature related to buildings, pavements, and bridges. Based on extensive experiments with the three case studies and on different network sizes, heuristic techniques proved its practicality for handling various network sizes. The performance of genetic optimization, on the other hand, was more efficient on small-scale networks but showed steep degradation in performance with large-scale problems. This research can be beneficial to municipalities and asset managers and can help them design efficient methods to sustain the safety and operability of the civil infrastructure, with least cost.

summary	We describe research exploring and demonstrating the use of large-scale data gathering and processing to inform the activities of architectural and urban designers. We apply this research to public spaces in urban housing estates. The aim is to understand the current use patterns and usability of these spaces, and to adaptively redesign them according to the insights gained from these findings. Another aim of the research is to obtain scientific knowledge regarding the production and use of user-data-based design support systems which promote and enhance the capability of (digital) design aids, such as building- and urban-scale models, to act as ‘learning devices’ giving designers better insights to the nature of the design situations they are asked to address, as well as insights on design space definition and exploration. We adopt a multimodal data collection strategy, consisting of participatory workshops for residents and users, person-based crowdsourcing, location-based crowd sensing, and statistical demographics data.

summary	The evaluation of a low-tech wind sensing platform for urban aerodynamic simulations relevant to pedestrian comfort. In this paper, the wind canyon effect is simulated with two different building morphologies. The platform provides conceptual knowledge of the dynamics in wind relevant for designers, architectural practitioners and students of design. Low-cost hot wire anemometry is utilised for the design of an Experimental Fluid Dynamic (EFD) wind sensing network interface. This paper explores the validity of the sensing platform for a new approach for non-wind engineers to gain a better understanding of the dynamics of wind. The influence of real-time feedback from quantified wind on the understanding of wind phenomena for non-wind engineers is discussed and compared with post analysis data. It was found that real-time quantified feedback from wind intrigues and stimulates the intuitive notion of wind dynamics through discussion, however post analysis remains critical to evaluate building design performance.

title	Printing Compound-Curved Sandwich Structures with Robotic Multi-Bias Additive Manufacturing
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_44
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.

summary	The aim of this paper is to investigate the applications both current and potential, of combining Augmented Reality (AR) and Building Information Modelling (BIM), providing an insight into attitudes towards utilising these technologies within the construction industry. This paper presents a study which has evaluated current research on the topic of AR and BIM, conducted semi structured interviews with a panel of industry experts and surveyed a sample group of 43 within the wider UK construction industry . Industry experts were interviewed using semi-structured interviews and results were thematically analysed with the data gathered from the literature review. 5 core themes used to structure a nine item industry and practitioner questionnaire. Results suggest that use of AR and BIM within the construction industry will continue to grow with the advent of emerging technologies. Use of AR and BIM combined with 3D Scanning, Wireless Sensory Network will also increase and the synergies between BIM and these emerging technologies will improve overall efficiencies in design, delivery, maintenance and demolition of projects. The findings of this study contribute further knowledge to understanding the implications and possibilities that utilising AR and BIM will have in the construction industry.

summary	This paper presents our Campus Information Model from a participatory perspective. The primary goal of our Campus Information Model (CIM) is to gather several disciplinary goals into a single model as the platform for collaboration. This intermediate-scale model integrates information and expert knowledge about a university campus design, including landscape planning and building design, allowing users to obtain quantitative feedback in real time to support design facilitating their specific goals. This paper describes first, the concept of collaboration; second, the collaborative system CIM; and third, the strategies to bring quantitative and qualitative goals to the same design environment.

doi	https://doi.org/10.52842/conf.caadria.2014.149
summary	This paper documents and critically reflects upon the design, development, fabrication, and implementation of three pavilion projects developed during 2013-14. The core investigation of this work is the production of architectural spaces characterized by a quality of enveloping, diffuse, visual and spatial atmospheres. The principal activity of the research is aimed at refining methods for software-based exploration of formal complexities and the subsequent need to control variability and efficiency in fabrication output, using Grasshopper for Rhino to develop customized definitions particular to each specific project scenario. Linking the projects together are issues of scale, resolution of effect, and intent to move from disparate assemblies of structure and skin toward composite, manifold construction techniques that address multiple concerns (gravity, bracing, affect, etc) with a minimum of assembly. A material palette common to the current vernacular of CNC-based projects such as plywood, plastics, and other sheet materials is utilised. This work is invested in extending the possibilities of the architect and architecture as a discipline, extrapolating the workflow from these successive projects to the speculative impact of the work upon emerging possibilities of architectural construction and craft.

summary	Research pavilions can serve as architectural scale demonstrations for the materialization of experimental forms and structures. Pavilions seek to prove and change methods of design and construction mechanisms in order to achieve desires such as material efficiency, novel spatial qualities and performative needs. The case of the ICD/ITKE Research Pavilion 2013-14 highlights the use of fiber composites in order to achieve a core-less filament winding modular system from bio-inspired lightweight structures through robotic fabrication. This paper describes the multi-disciplinary design and construction process of this pavilion that created a structure of out 36 unique components.
