title	Point Cloud Segmentation for Building Reuse - Construction of digital twins in early phase building reuse projects
doi	https://doi.org/10.52842/conf.ecaade.2023.2.327
source	Dokonal, W, Hirschberg, U and Wurzer, G (eds.), Digital Design Reconsidered - Proceedings of the 41st Conference on Education and Research in Computer Aided Architectural Design in Europe (eCAADe 2023) - Volume 2, Graz, 20-22 September 2023, pp. 327–336
summary	Point cloud processing has come a long way in the past years. Advances in computer vision (CV) and machine learning (ML) have enabled its automated recognition and processing. However, few of those developments have made it through to the Architecture, Engineering and Construction (AEC) industry. Here, optimizing those workflows can reduce time spent on early-phase projects, which otherwise could be spent on developing innovative design solutions. Simplifying the processing of building point cloud scans makes it more accessible and therefore, usable for design, planning and decision-making. Furthermore, automated processing can also ensure that point clouds are processed consistently and accurately, reducing the potential for human error. This work is part of a larger effort to optimize early-phase design processes to promote the reuse of vacant buildings. It focuses on technical solutions to automate the reconstruction of point clouds into a digital twin as a simplified solid 3D element model. In this paper, various ML approaches, among others KPConv Thomas et al. (2019), ShapeConv Cao et al. (2021) and Mask-RCNN He et al. (2017), are compared in their ability to apply semantic as well as instance segmentation to point clouds. Further it relies on the S3DIS Armeni et al. (2017), NYU v2 Silberman et al. (2012) and Matterport Ramakrishnan et al. (2021) data sets for training. Here, the authors aim to establish a workflow that reduces the effort for users to process their point clouds and obtain object-based models. The findings of this research show that although pure point cloud-based ML models enable a greater degree of flexibility, they incur a high computational cost. We found, that using RGB-D images for classifications and segmentation simplifies the complexity of the ML model but leads to additional requirements for the data set. These can be mitigated in the initial process of capturing the building or by extracting the depth data from the point cloud.

summary	Creating virtual city models at different scales, emphases and overall orientations is a topic that has attracted great interest in architectural and urban planning context over at least the last two decades. However the complexity of the city as a historical formation demands new methods of representation embracing interactive technologies. The work discussed in this paper is part of a large multidisciplinary project for the development of the Volos city museum. Enhancing the interaction between the public and the museum exhibits is essential. The paper focuses on the definition, complexity and orientation of the data structures and the integration of 3D contemporary and historic data that is the backbone for the digital representations and the interactive applications developed for the museum.

title	Digital system of tools for public participation and education in urban design: Exploring 3D ICC
doi	https://doi.org/10.52842/conf.ecaade.2012.1.383
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 1 / ISBN 978-9-4912070-2-0, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 383-392
summary	This article is a starting point for the development of experiential urban co-design interfaces to enhance public participation in local urban projects and to be also used as a communication and collaboration tool in urban design. It is based on the previous research involving 3D city models utilized as understandable design interfaces for the non-technical public (Jutraz, Zupancic, 2011), where we have already explored different views (pedestrian, intermediate and bird’s-eye view), as well as the means by which the information obtained from these different views may be combined by shifting between viewpoints. Previous work was conducted in the “street lab” as well as the Urban Experimental Lab, which was developed specifi cally for the public’s participation in urban planning (Voigt, Kieferle, Wössner, 2009). Presented in this article is the next step that explores the immersive collaboration environment 3D ICC [1], formerly known as Teleplace. The environment was developed for effi cient collaboration and remote communication and shifts the research focus towards questions regarding how to employ both labs as interfaces between the non-technical public and design professionals. As we are facing the lack of digital systems for public participation and education in urban design, different digital tools for communication and collaboration should be combined into a new holistic platform for design. A digital system of tools needs to be developed that supports the urban design decision-making process and focuses on improved final solutions and increased satisfaction amongst all participants. In this article the system of digital tools for public participation, which include communication, collaboration and education, will be also defi ned, with its basic characteristics and its elements.

source	SIGraDi 2012 [Proceedings of the 16th Iberoamerican Congress of Digital Graphics] Brasil - Fortaleza 13-16 November 2012, pp. 414-418
summary	This paper investigates the relation between the shading condition and geometrical configuration of neighborhood-scale developments. It introduces a straightforward method for measuring shadow areas casted on buildings’ roofs and facades – in urban areas – using digital 3D models. Employing this method for measuring shadow areas in nine neighborhoods in Jinan, China, at six different time points on summer and winter solstices – a total of 54 sample measurements – this study develops two regression models that reveal the significant dependency of the in-shadow percentage of buildings’ façade and roof areas to the building volume density (BVD) and height irregularity (HI) of the urban fabric.

summary	In this paper we present an environment for conceptual design which mimicsthe interaction of designers with physical mockups. We present novel three dimensional on-and-above-the-surface interactive techniques which combine asymmetric bimanual operations with multi-touch direct manipulation on a fl at surface and depth cameras. These take advantage of a continuous interaction space to create and edit 3D models in a stereoscopic environment. To allow modeling architectural shapes directly, we combine hand and finger tracking in the space above the table with multi-touch on its surface without the need to change modes. This provides an alternative design environment where users can seamlessly switch between interacting on the surface or in the space above it depending on the task, which makes it easier to model complex shapes using simple operations.

title	Three Dimensional Reconstitution of an Old Town from Historical Documents: Case of the Medina of Jijel in Algeria
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 191; 285-303
summary	The three-dimensional reconstitution of cities and urban tissues was the subject of several studies and researches. In order to obtain the acquisition of the geometry of architectural or urban sets, some studies are based on Photogrammetric or on computer vision. Others have focused on the development of tools of acquisition from a laser providing a 3D scatter plot. Some of them yet focused towards the development of CAD software. The automatic generation for morphological 3D representation based on the exploitation of the architectural knowledge basis is also an option. This type of work becomes more relevant and legitimate when it concerns old cities in state of ruin or more simply missing whose remains only prints or literary descriptions similar to our case study; the old town of Jijel that many people ignore its existence. The aim of this work is to achieve a 3D reconstitution of buildings of this town based on historical documents, mostly prints, digitized old maps and plans, as well as literary texts (tales of travelers, military records, and history books). The method developed can solve and generate possible urban volumes in the most frequent cases. The 3D model obtained, despite its geometric simplicity, can view the city from different angles and open new opportunities for research in history, architecture and town planning.

title	Numerical Simulation of Effect of Urban Geometry Layouts on Wind and Natural Ventilation Under Mediterranean Climate
source	CAAD \| INNOVATION \| PRACTICE [6th International Conference Proceedings of the Arab Society for Computer Aided Architectural Design (ASCAAD 2012 / ISBN 978-99958-2-063-3], Manama (Kingdom of Bahrain), 21-23 February 2012, pp. 195-202
summary	The use of the method "simulation" of the microclimate for an urban site presents much of interest; because this can serve as us observation and analysis of the consequences of various scenarios relating to the existence and the importance of the constituent elements in urban space. Wind in outdoor urban space is among the most difficult parameters to identify and control field given its instability. Currently, in the field of the ventilation, there are some outdoor spaces simulation tools, used to assess the flow of the wind at different spatial scales. The aim of this research is to demonstrate the effect of the urban geometry of the layout on the wind movement and the outdoor natural ventilation. However, this study investigated the effect on outdoor thermal comfort of a building layouts in a planned residential area situated in the city of Jijel humid Mediterranean region of Algeria. In order to improve outside comfort in this open space, a 3D numerical simulation tool ENVI-met 3.1 beta 4 was used to simulate the urban thermal climate taking into account various scenarios. Thus, simulation’s results are discussed in this paper

title	Shading With Folded Surfaces: Designing With Material, Visual and Digital Considerations
doi	https://doi.org/10.52842/conf.ecaade.2012.2.613
source	Achten, Henri; Pavlicek, Jiri; Hulin, Jaroslav; Matejovska, Dana (eds.), Digital Physicality - Proceedings of the 30th eCAADe Conference - Volume 2 / ISBN 978-9-4912070-3-7, Czech Technical University in Prague, Faculty of Architecture (Czech Republic) 12-14 September 2012, pp. 613-620
summary	This paper analyses a hybrid design approach; how physical and digital processes can inform each other in a multivalent design cycle. It describes the design of origami-inspired window shades, part of the Shaping Light project that explores how adjustable surface structures can modulate light levels and heat gain in response to the changing seasons. The screen uses sloped surfaces to diffuse light and create apertures that close when the screen is stretched and open when the screen is folded. The project complements digital methods for pattern proportioning and kinetic simulation with manual manipulation to generate 3D folding motifs and refi ne assemblies. Physical prototypes can shape digital refi nement by revealing visual and structural characteristics of materials, along with joint and production considerations. Physical models for simulating sunny and cloudy daylighting conditions provide a direct connection between spatial confi guration and visual effects. The paper concludes with guidelines for material-based digital-analog creation.

title	Architecture, Digital Techniques & Project Management

summary	With the invention of computers, Architecture and other Engineering disciplines have undergone revolutionary developments offering new opportunities for improving efficiency and opening new frontiers for creativity. For example in architecture and urban planning, the discussions have been extended from conventional writings to cover cyberspace, virtual architecture and digital city. Moreover, computers have helped in the realization of many complex projects that would be inconceivable with traditional drawing techniques. This is clearly demonstrated in the works of Frank Gehry's, Zaha Hadid, Daniel Libeskind and many others. In deed, digital techniques have changed the design creative process and how the architects think. Traditionally the structured development architectural ideas from 2D drawings (plans, sections, elevations) towards 3D resolution has been replaced by more interactive approach of 2D & 3D. The changes that digital techniques have brought to the field of Architecture; including practice and education, can obviously be viewed from different angles and incite many discussions and questions. However, the purpose of this presentation is to discuss the role of digital techniques within the overall framework of project management in Gulf Housing Engineering. It starts the discussion with a brief on architecture and digital techniques in the Gulf Region, especially during the “boom period”; a period characterized by rapid production of buildings relying heavily on virtual images. It is against this background, the role of digital techniques is evaluated from a practice point of view. In fact in GHE, digital means are integral parts of the holistic project delivery process starting form initiation, to various design stages to construction ending with project completion. In this process emphasis is paid to the inter-relationships between IT Systems and Quality Control which in turn facilitate measuring, monitoring and reporting on various managerial, technical and design and budgetary aspects of the project. The presentation is supported by real case studies of GHE portfolio. It emphasizes that digital techniques should be an integral part of an overall process and should be seen as means to enhance efficiency and creativity; and should contribute to the betterment of the built environment

summary	The aim of this paper is to report the teaching experience held in 2012 at Unicamp between three disciplines of representation. Students analyzed emblematic residences from digital and physical models. Digital models were produced in Revit and its building components were diagrammed in AutoCad. After that, these elements were sent to laser cutter, and hand assembled. In 3DS Max, 3D model allowed simulations such as rendered images and animations. We report the contributions of these analog and digital artifacts in the design process. This article contributes to reflection and debate on the application of digital technologies in the analysis of iconic buildings of architecture.

summary	2D GIS has shown its limitations in many situations, especially when it’s applied in urban design. Many studies have been carried out to deal with the problem. Some attempted to link 3D visualisation to data stored within 2D GIS, and others tried to combine GIS, CAD and visualisation together. They all aim to meliorate current GIS for 3D applications. The authors of this paper developed a preliminary prototype of a 3D urban space information system based on Google Earth Plugin. It sets up a server to store and offer specific urban space information. With the desktop application that embeds Google Earth Plugin, user can upload and download models on the server, view them in the virtual 3D environment of Google earth, and make models directly in the 3D environment. A server-side database plays the role of managing information. This paper introduces the key ideas and methods of the system development, including system structure, set-up of the serve, server side information management, and interactive modelling functions.

title	Real-time rendering of large building information models: Current state vs. state-of-the-art
doi	https://doi.org/10.52842/conf.caadria.2012.647

summary	With the use of Building Information Models (BIM), real-time 3D visualisations have become a natural tool in order to communicate ideas and share information between all involved parties in a project. Currently, several different BIM viewers are available for the purpose of interactive presentations and design reviews. However, as BIMs become larger and more detailed, it provides a challenge for available software solutions to manage them interactively. In this paper we present our findings from analysing three commonly used BIM viewers - Tekla BIMSight, Autodesk Navisworks and Solibri Model Viewer - in terms of real-time rendering performance. In addition we have developed a prototype BIM viewer to test modern approaches for efficient real-time rendering. Specifically, we have implemented the latest version of the Coherent Hierarchical Culling algorithm. Our results show that existing BIM viewers all share limitations in their ability to handle large and complex BIMs interactively. However, for the same test models, our prototype BIM viewer enables smooth real-time performance with no visual artefacts. The results from our tests thus shows that the technology to enable correct real-time rendering of large and complex BIMs is already accessible, but are currently not utilised by any of the tested BIM viewers.

title	Building Thailand's tallest Ganesh: CAD/CAM integration in conventional metal fabrication
doi	https://doi.org/10.52842/conf.caadria.2012.337
source	Proceedings of the 17th International Conference on Computer Aided Architectural Design Research in Asia / Chennai 25-28 April 2012, pp. 337–346
summary	Ganesh (Ganesa or Ganesha) is a Hindi god well known for his distinguishable elephant head and widely revered as the god of success or remover of obstacles. Patrons in Thailand have worshipped Ganesh and respected him by means of erecting statues of Ganesh in various poses and sizes throughout the country. In late 2008, the people of Chacheongsao, a province located East of Bangkok, decided to create Thailand’s tallest standing Ganesh statue made with bronze reaching heights up to 39 meters and situated on the Bangpakong river bank overseeing the city and its people. The author and design team was approached by representatives from Chacheongsao and commissioned to advise the process from conception to construction. The challenge started with seeking appropriate computer-aided design and manufacturing technologies and innovative processes to guide the design team throughout the production. The 0.60-meter bronze cast sculpture of the Ganesh was scanned using a 3D optical scanner to generate a solid model of the statue. A surface model was then extracted from the 3D model to firstly determine the most efficient structural support within the statue and secondly to generate surface strips for the foundry to create actual bronze casts. The construction of the project began early 2009 and the statue has since been erected from its base to currently its head. During construction, the author and design team has encountered several problems translating pixels to parts. Several errors have occurred during the mould and cast production process as well as construction errors on site causing mismatches of the structure and surface, misalignments, and protruding structural supports and joints. The lessons learned from this project is documented and analysed with hopes to create a more effective process for future projects with similar requirements.

summary	Previous research (Bourdakis et al, 2012; Papasarantou et al, 2013) dealt with the problem of creating information visualisation systems capable of combining historical data of MUCIV's database and developing strategies that embed the non-spatial data in spatial models. The database was primarily designed as an experimental flexible spatio-temporal configuration of dynamic visual structures generating a variety of narrations through interaction.The attempt of producing a legible configuration driven by a number of criteria, led to the proposition of two different arrangements, namely the linear and radial array. The aim of this paper is to present the next step on the visualization after redefining both the way that thematic axes and data are visualized and arranged/scattered. Alternate configurations are investigated, based also on theoretical analysis on the conceptualization and perception of information visualization systems (Card et al 1999, Ware, 2004).

summary	In the context of a wider inquiry on the integration of material properties and construction processes in computational models, this paper proposes a digital model for fabric formwork panels. Plaster cast in different types of fabric can produce a significant variation of resulting forms. The aim is to investigate whether data retrieved from physical models with 3D scanning techniques can improve the accuracy and efficiency of a simulation based on geometric principles, and better predict the behaviour of cast material in relation to the type of fabric. Setting up the computational model and choosing its parameters and constraints is based on the physical construction process, highlighting the relationship between material and form. As part of the cyclical exchange, evaluation of the digital model with physical testing demonstrates that the simulation can actually be trained by reducing the physical/ digital discrepancies.

summary	3D digital models allow the visualization of both the historical and morphological evolution of a building - combined with its environment and transformations - as well as, its survey, record and pre-view of the impact of future interventions. Furthermore, the employment of digital technology offers a great advance in the field of cultural good’s documentation by including not only tangible issues but also iconographic elements, materials information and constructive pathology survey, to mention a few. This kind of models had become an open documentary system, and they should be considered essential in every architectural heritage conservation´s project.
