title	Application and evaluation of digital image techniques in close range photogrammetry
source	University of Innsbruck
summary	Most of the orthomapping techniques that are used in the present are restricted to surfaces that arise from a function of 'ground co- ordinates' z = f (x, y) , so-called 2.5D objects. Some techniques are also restricted to surfaces with kind of smooth shape or even to regular surfaces, but all of them are established to rectify images (although increasingly digitally). A new approach has been established for digital restitution and orthomapping of close range objects of almost any shape and size and with almost no restriction to images or objects. The idea of this approach is an inversion of the photographic technique and is (on the contrary to the 'rectification approach') strictly object oriented. All of the objects are regarded to be describable in their geometrical shape by a number of particular faces that can be regular or irregular but can anyway be created in a CAD environment. The data needed to get this surface can come from any photogrammetric, tachometric or other source with any particular one wants to have for the results. All the details that lie on that surface don't have to be restituted by analog or analytical point measurement but can after that be projected onto this surface from any photo, from any side and with any camera they have been taken. A 'Digital Projector' does the projection of the photos from the same positions and with the same inner orientation as of photographic camera. Using this approach any measurements of any details on the facades can be done easily. No details of the object can be neglected, none can be forgotten, no prior filtering of details has preceded this using. The full information of the original photos is available in the results. The results of the restitution can be presented in many ways. One of them is create orthoimages in any scale. Other results are any perspective or parallel view of the object. Other use of the strict 3D map-covered object for visualization (e.g. in architecture and archaeology application) is possible

title	How a Flooded City Can Be Visualized from Both the Air and the Ground with the City Digital Twin Approach, System Integration of Flood Simulation and Augmented Reality with Drones
source	Jeroen van Ameijde, Nicole Gardner, Kyung Hoon Hyun, Dan Luo, Urvi Sheth (eds.), POST-CARBON - Proceedings of the 27th CAADRIA Conference, Sydney, 9-15 April 2022, pp. 607-616

summary	City digital twins are becoming increasingly important for the sustainable development of cities, and augmented reality (AR) has been attracting attention as a tool for visualizing city digital twins. In addition, from the perspective of SDG 11, it is essential to manage flood risk in urban spaces. However, there are no case studies that present a bird‚s-eye view of a simulated city. Visualizing the state of a flooded city during a disaster is one potential use case. From the perspective of information graphics, people want to understand urban data at the micro and macro levels. This study proposes a city-digital-twin approach for visualizing a simulated city using a large-scale AR and drone integration method that does not require a specific software development kit (SDK). This system can visualize the state of a city flooded by a disaster from both a bird‚s-eye view of the city at several tens of metres above it and from a first-person perspective of the user‚s area of activity. The applicability of the system is demonstrated through verification and case studies.

title	ARCHITECTURAL GRAPHICS: TRADITIONAL AND DIGITAL COMMUNICATION
source	Prentice Hall (ISBN: 0-13-341967)
summary	The media used to create architectural drawings are now more varied than ever before. Basic principles of drawing types, from two-dimensional orthographic projections (plans, elevations, etc.) to perspective to axonometrics are media independent. While "what the images are" may be constant, the way in which they are created and modified is, at time, media dependent and therefore variable. Because we can only modify what we create, the way an image or model is created (and therefore the media employed) affects its future uses and possibilities. Architectural Graphics is written from the point of view of today's architects - one who must be comfortable working in a variety of media. A variety of diagrams, photos, and simple drawings combine with well-executed finished samples to illustrate the basic principles of graphic communication, as well as the specific characteristics of both traditional and digital media.

title	Reconfigurable molds and a fabrication-aware design tool for manufacturing concrete grid structures
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 420–433
summary	The design and manufacturing of concrete elements need to be reconsidered in light of current trends in architectural geometry. Today, there is a movement toward greater customization and adaptability of concrete elements using “reconfigurable formworks” and “additive manufacturing.” Our study approached the issue of fabricating non-standardized concrete elements from the perspective of a “reconfigurable fabrication platform.” Specifically, we developed a method of fabricating geometrically diverse concrete joints by combining flexible pressure-enduring tubes with a rigid mechanism, resulting in an adaptive concretecasting machine. This platform, which we named “Flexi-node,” can be used in conjunction with a relevant fabrication-aware digital design tool. Users can computationally design and fabricate a great variety of concrete joints using just one mold, with a minimum of material waste and with no distortion from hydrostatic pressure as would typically occur in a fully flexible formwork

title	ZeroWaste - Towards Computing Cooperative Robotic Sequences for the Disassembly and Reuse of Timber Frame Structures
source	ACADIA 2022: Hybrids and Haecceities [Proceedings of the 42nd Annual Conference of the Association of Computer Aided Design in Architecture (ACADIA) ISBN 979-8-9860805-8-1].

summary	ZeroWaste is a project about repositioning existing timber building stock within a circular economy framework. Rather than disposing of these buildings at the end of their life, the goal is to view them as stores of valuable resources that can be readily reused. By doing this, material life cycle becomes an integral design consideration alongside planning for the efficient disassembly and reuse of these structures. In this paper, the computational workflow is presented for the first phase of the project: planning a cooperative robotic disassembly sequence for the scaffold-free removal of members from existing timber structures.

title	The use of reinforced learning to support multidisciplinary design in the AEC industry: Assessing the utilization of Markov Decision Process
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 216–237
summary	While the design practice in the architecture, engineering, and construction (AEC) industry continues to be acreative activity, approaching the design problem from a perspective of the decision-making science hasremarkable potentials that manifest in the delivery of high-performing sustainable structures. These possiblegains can be attributed to the myriad of decision-making tools and technologies that can be implemented toassist design efforts, such as artificial intelligence (AI) that combines computational power and data wisdom.Such combination comes to extreme importance amid the mounting pressure on the AEC industry players todeliver economic, environmentally friendly, and socially considerate structures. Despite the promisingpotentials, the utilization of AI, particularly reinforced learning (RL), to support multidisciplinary designendeavours in the AEC industry is still in its infancy. Thus, the present research discusses developing andapplying a Markov Decision Process (MDP) model, an RL application, to assist the preliminary multidisciplinary design efforts in the AEC industry. The experimental work shows that MDP models can expediteidentifying viable design alternatives within the solutions space in multidisciplinary design while maximizingthe likelihood of finding the optimal design

title	Kit-of-Parts Fabrication and Construction Strategy of Timber Roof Structure - Digital design-to-production workflow for self-builders

summary	This project builds upon a premise that complex double-curved geometries can be built out of simple, planar, and straight elements. As such, it is possible to simplify manufacturing, construction, and assembly processes, as well as decrease the delivery time and cost. When operating with planar and simple components in the form of Kit-of- Parts there is an assumption that such components can be easily used by self-builders, not necessarily building experts. This can empower participatory activities leading to a more sustainable and resilient engaged community. This hypothesis is evaluated through the process of design for manufacture and assembly project of the timber shell, supported by proposed advanced computational design-to-production workflow utilising digital fabrication technologies such as CNC machining and robotic milling. The assembled and erected structure is evaluated in the scope of constructability, deliverability, and operability. Therefore, the focus of this project is to test, observe, experiment with, and learn from those aspects from the perspective of a fabricator, maker, and self-builder of the double-curved timber roof structure, while operating with smaller-scale components and smaller sub-assemblies, convenient for hands-on operations. The paper also discusses the limitations of such an approach.

summary	This project explores the advantages of employing continuum material topology optimization in a 3D non-standard lattice structure through fiber additive manufacturing processes (Figure 1). Additive manufacturing (AM) has gained rapid adoption in architecture, engineering, and construction (AEC). However, existing optimization techniques often overlook the mechanical anisotropy of AM processes, resulting in suboptimal structural properties, with a focus on layer-by-layer or planar processes. Materials, processes, and techniques considering anisotropy behavior (Kwon et al. 2018) could enhance structural performance (Xie 2022). Research on 3D printing materials with high anisotropy is limited (Eichenhofer et al. 2017), but it holds potential benefits (Liu et al. 2018). Spatial lattices, such as space frames, maximize structural efficiency by enhancing flexural rigidity and load-bearing capacity using minimal material (Woods et al. 2016). From a structural design perspective, specific non-standard lattice geometries offer great potential for reducing material usage, leading to lightweight load-bearing structures (Shelton 2017). The flexibility and freedom of shape inherent to AM offers the possibility to create aggregated continuous truss-like elements with custom topologies.

title	Urban scale digital twins in data-driven society: Challenging digital universalism in urban planning decision-making
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 238–253
summary	The article examines the impact of the virtual public sphere on how urban spaces are experienced andconceived in our data-driven society. It places particular emphasis on urban scale digital twins, which arevirtual replicas of cities that are used to simulate environments and develop scenarios in response to policyproblems. The article also investigates the shift from the technical to the socio-technical perspective withinthe field of smart cities. Despite the aspirations of urban scale digital twins to enhance the participation ofcitizens in the decision-making processes relayed to urban planning strategies, the fact that they are based on alimited set of variables and processes makes them problematic. The article aims to shed light on the tensionbetween the real and the ideal at stake during this process of abstracting sets of variables and processes in thecase of urban scale digital twins

title	Exploring Virtual Reality as an Approach to Resurrect Destroyed Historical Buildings: An Approach to Revive the Destroyed "Egg Building" through VR
source	Hybrid Spaces of the Metaverse - Architecture in the Age of the Metaverse: Opportunities and Potentials [10th ASCAAD Conference Proceedings] Debbieh (Lebanon) [Virtual Conference] 12-13 October 2022, pp. 609-631
summary	An important part of a city, that gives it a sense of community and character, is its history. One way of acknowledging this heritage is by preserving historic building and structures. Old buildings are witnesses to the aesthetic and cultural history of a city, helping to give people a sense of place and connection to the past. Unfortunately, despite their importance within the city, historical buildings are most of the time subject to demolition and to be replaced- leaving behind stories told and untold of what use to be. The paper, therefore, aims to explore the capability of the metaverse, using virtual reality touring, to revive the memory of historical buildings that are subject to fade. Where preserving historical buildings can not only act as a symbol of grandeur but is also vital for reviving the community’s collective memory. The case study focused upon in the research paper shows a first step in the development of an immersive virtual tour for the significant building of “The Egg” or “Beirut City Center” in Downtown- which is a building that witnessed a series of unfortunate events that lead to destruction, erasure, and demolition of the building. Therefore, examining the recovery and revival of this unique historic site in an unconventional way which is in the metaverse, specifically the Virtual Reality (VR). The paper assumes that virtual reality, as the main metaverse approach, would help people ‘remember’ and ‘mentally revive’ the destroyed historical buildings that once acted as the building blocks in the impacted city. To prove this hypothesis, two different methodologies will be used, by theorical analysis and literature review, such as analyzing the main keyword, and analyzing datum from previous works. The second method will rely on the physical methodology, where virtual 3D Models will be built in a computer software, Autodesk Revit, then imported within a VR experience for an enhanced experience within the historical site to preserve the historic buildings and revive the collective memory within the community, enabling people to view how these historic sites once were and how they have now become.

summary	To broaden the understanding of what has been studied on the topic of microinteractions in human-computer interaction, this article conducts an exploratory study to survey the scientific production in articles and dissertations that work with the microinteractions framework, by Saffer (2013), applied to the scope of the user experience. As a method, a systematic literature review is proposed. For this, the following scientific bases are used: Scopus Elsevier, Capes Periodicals, EBSCO and Proquest. From the perspective of design and human-computer interaction, the quantity and approaches used are investigated. Of the 731 scientific works found, 14 were filtered and selected to compose the panorama of scientific research in microinteractions. The article brings the main approaches used in microinteractions research that focus on user experience in the last decade and points out perspectives on how to investigate microinteractions in future academic research.

title	The Spatial Environment Affects Human Emotion Perception-Using Physiological Signal Modes

doi	https://doi.org/10.52842/conf.caadria.2022.2.425
summary	In the past, spatial design was mainly from the perspective of designers. With the increasing demand for quality spaces, contemporary architecture has gradually shifted from focusing on form creation to human well-being, once again advocating the concept of "human-centered" spatial design. Exploring how the spatial environment affects human emotions and health is conducive to quantifying the emotional perception characteristics of space and promoting the improvement of human quality of life and sustainable survival. At the same time, the development of contemporary technology and neuroscience has promoted the study of the impact of spatial environment on human emotion perception. This paper summarizes the research on the impact of the spatial environment on human emotion perception in recent years. First, 28 relevant studies were screened using the PRISMA framework. Then a set of research processes applicable to this study is proposed. Next, the physiological signals currently used to study the effects of the spatial environment on human emotions are summarized and analyzed, including electroencephalography (EEG), skin response (GSR), pulse (PR), and four other signals. The architectural features studied in the related literature are mainly building structural features, building spatial geometric features, and building spatial functional attributes. The study of urban space is divided into different parts, such as urban environment characteristics and urban wayfinding behavior. Finally, we point out the shortcomings and perspectives of studies related to the influence of spatial environment on human emotion perception.

summary	This paper contributes the current research state and possible future developments of AI-based autocompletion of architectural floor plans and shows demand for its establishment in computer-aided architectural design to facilitate decent work, economic growth through accelerating the design process to meet the future workload. Foundations of data representations together with the autocompletion contexts are defined, existing methods described and evaluated in the integrated literature review, and criteria for qualitative and sustainable autocompletion are proposed. Subsequently, we contribute three unique deep learning-based autocompletion methods currently in development for the research project metis-II. They are described in detail from a technical point of view on the backdrop of how they adhere to the proposed criteria for creating our novel AI.

summary	This paper provides a brief overview of how technology might be considered an extension of the self from early cybernetics research onwards. It then explores how a robotic extension could engage with the critical feminist issue of “the male gaze.” In doing so, it provides a brief theoretical context to the notion of the gaze and visual behavior from a cognitive science and neuroscience point of view, and then explores it in the context of a discourse on visual culture and feminism. Finally, it illustrates the application of such a critical concept through the example of a robotic installation developed by the author for Milan Fashion Week in collaboration with Universal Robots.

summary	Round-the-Table, as a researcher-led initiative, was an experimental virtual roundtable in a 3D format that invited twenty-one organisations worldwide from education, research, and technology to open a broad dialogue about a more sustainable, inclusive, interactive, and accessible educational environment, which may help pedagogical communication beyond the 2D frame. This was made possible by the implementation of a Web-VR platform supported by Mozilla, by which each participant had the opportunity to co-create with the organisers, a collaborative immersive sensory experience, together with the simultaneous dialogue between Local and Global. Participants were asked two critical questions: ‘decentralised education’ and ‘phygital exchanges’ : how can we work beyond the 2d frame and how to distribute tasks between physical and digital. The responses were by far diverse, but it was indeed possible to map a cohesive picture from this cloudy but colourful panorama.

title	Performance comparison analysis of 3D reconstruction modeling software in construction site visualization and mapping
source	International Journal of Architectural Computing 2022, Vol. 20 - no. 2, pp. 453–475
summary	Unmanned aerial vehicle (UAV) technology has overcome the limitations of conventional construction management methods using advanced and automated visualization and 3D reconstruction modeling techniques. Although the mapping techniques and reconstruction modeling software can generate real-time and high-resolution descriptive textural, physical, and spatial data, they may fail to develop an accurate and complete 3D model of the construction site. To generate a quality 3D reconstruction model, the construction manager must optimize the trade-offs among three major software-selection factors: functionalities, technical capabilities, and the system hardware specifications. These factors directly affect the robust 3D reconstruction model of the construction site and objects. Accordingly, the purpose of this research was to apply nine well-established 3D reconstruction modeling software tools (DroneDeploy, COLMAP, 3DF+Zephyr, Autodesk Recap, LiMapper, PhotoModeler, 3D Survey, AgiSoft Photoscan, and Pix4D Mapper) and compare their performances and reliabilities in generating complete 3D models. The research was conducted in an eco-home building at the University of Technology, Malaysia. A series of regression analyses were conducted to compare the performances of the selected 3D reconstruction modeling software in alignment and registration, distance computing, geometric measurement, and plugin execution. Regression analysis determined that among the software programs, LiMapper had the strongest positive linear correlation with the ground truth model. Furthermore, the correlation analysis showed a statistically significant p-value for all software, except for 3D Survey. In addition, the research found that Autodesk Recap generated the most-robust and highest-quality dense point clouds. DroneDeploy can create an accurate point cloud and triangulation without using many points as required by COLMAP and LiMapper. It was concluded that most of the software is robustly, positively, and linearly correlated with the corresponding ground truth model. In the future, other factors involving software selection should be studied, such as vendor-related, user-related, and automation factors.

title	PlacemakingAI : Participatory Urban Design with Generative Adversarial Networks

summary	Machine Learning (ML) is increasingly present within the architectural discipline, expanding the current possibilities of procedural computer-aided design processes. Practical 2D design applications used within concept design stages are however limited by the thresholds of entry, output image fidelity, and designer agency. This research proposes to challenge these limitations within the context of urban planning and make the design processes accessible and collaborative for all urban stakeholders. We present PlacemakingAI, a design tool made to envision sustainable urban spaces. By converging supervised and unsupervised Generative Adversarial Networks (GANs) with a real-time user interface, the decision-making process of planning future urban spaces can be facilitated. Several metrics of walkability can be extracted from curated Google Street View (GSV) datasets when overlayed on existing street images. The contribution of this framework is a shift away from traditional design and visualization processes, towards a model where multiple design solutions can be rapidly visualized as synthetic images and iteratively manipulated by users. In this paper, we discuss the convergence of both a generative image methodology and this real-time urban prototyping and visualization tool, ultimately fostering engagement within the urban design process for citizens, designers, and stakeholders alike.

summary	With the ascendance of Generative Adversarial Networks (GAN), promising prospects have arisen from the abilities of machines to learn and recognize patterns in 2D datasets and generate new results as an inspirational tool in architectural design. Insofar as the majority of ML experiments in architecture are conducted with imagery based on readily available 2D data, architects and designers are faced with the challenge of transforming machine-generated images into 3D. On the other hand, GAN-generated images are found to be able to learn the 3D information out of 2D perspectival images. To facilitate such transformation from 2D and 3D data in the framework of deep learning in architecture, this paper explores making new architectural forms from flat GAN images by employing traditional tools of projective geometry. The experiments draw on Brook Taylor’s 19th- century theorem of inverse projection system for creating architectural form from perspectival information learned from GAN images of Swiss alpine architecture. The research develops a parametric tool that automates the dimensional transformation of 2D images into 3D architectural forms. This research identifies potential synergic interactions between traditional tools and techniques of architects and deep learning algorithms to achieve collective intelligence in designing and representing creative architecture forms between humans and machines.

summary	This essay is part of an ongoing research entitled “The 360? immersive: investigation, representation and digital immersion of Rio de Janeiro city during 19th and 20th centuries”, developed in Universidade Federal do Rio de Janeiro / Programa de Pós-Graduçao em Urbanismo, Brazil, which presents, analyses and discuss in a theoretical-conceptual approach The Panorama of Rio de Janeiro, by Victor Meirelles and Henri Langerock by the Unity Game Engine. To achieve this 360? immersion experience a methodological path was developed: restitution of the Panorama and its visualization in real time; the transition from the Lumion model to the Unity Game Engine; resizing the model scale; the immersive experience beyond the observation platform: the faux-terrain experienced; viewer movement, scenes, scripts, and navigation menus.

summary	Citizen participation in urban planning and architectural design has been long discussed and experimented with since the 1960s. With existing participatory design approaches, two key challenges can be identified. First, the power of citizens to directly affect the decision-making processes is typically quite limited. Second, the use of traditional face-to-face design workshop results in low levels of participation. This paper proposes an innovative participatory design approach with a focus on co-design and co-decision. The co-design stage provides citizens with a tool that empowers them to think critically of their built environment and to initiate design development in their own city. The co-decision stage gives citizens real power in determining the future changes to their city by embedding the participatory design approach into the planning permission system. This participatory design approach is implemented through a web application that allows participants to view design proposals within the existing site context from a birds-eye views and from multiple immersive views, leading to a better understanding of the design proposal‚s scale and impact. The design proposal viewer has been demonstrated on a heritage site in Singapore, showing its potential to be used as evidence for supporting or rejecting design proposals.
