Abstract:
The centre vortex structure of the vacuum is visualised through the use of novel 3D visualisation techniques. These visualisations allow for a hands-on examination of the centre-vortex matter present in the QCD vacuum, and highlights some of the key features of the centre-vortex model. The connection between topological charge and singular points is also explored. This work highlights the useful role visualisations play in the exploration of the QCD vacuum.

Abstract:
The opportunities for 3D visualisations are huge. People can be immersed inside their data, interface with it in natural ways, and see it in ways that are not possible on a traditional desktop screen. Indeed, 3D visualisations, especially those that are immersed inside head-mounted displays are becoming popular. Much of this growth is driven by the availability, popularity and falling cost of head-mounted displays and other immersive technologies. However, there are also challenges. For example, data visualisation objects can be obscured, important facets missed (perhaps behind the viewer), and the interfaces may be unfamiliar. Some of these challenges are not unique to 3D immersive technologies. Indeed, developers of traditional 2D exploratory visualisation tools would use alternative views, across a multiple coordinated view (MCV) system. Coordinated view interfaces help users explore the richness of the data. For instance, an alphabetical list of people in one view shows everyone in the database, while a map view depicts where they live. Each view provides a different task or purpose. While it is possible to translate some desktop interface techniques into the 3D immersive world, it is not always clear what equivalences would be. In this paper, using several case studies, we discuss the challenges and opportunities for using multiple views in immersive visualisation. Our aim is to provide a set of concepts that will enable developers to perform critical thinking, creative thinking and push the boundaries of what is possible with 3D and immersive visualisation. In summary developers should consider how to integrate many views, techniques and presentation styles, and one view is not enough when using 3D and immersive visualisations.

Abstract:
Mutual awareness of visual attention is essential for collaborative work. In the field of collaborative virtual environments (CVE), it has been proposed to use Field-of-View (FoV) frustum visualisations as a cue to support mutual awareness during collaboration. Recent studies on FoV frustum visualisations focus on asymmetric collaboration with AR/VR hardware setups and 3D reconstructed environments. In contrast, we focus on the general-purpose CVEs (i.e., VR shared offices), whose popularity is increasing due to the availability of low-cost headsets, and the restrictions imposed by the pandemic. In these CVEs collaboration roles are symmetrical, and the same 2D content available on desktop computers is displayed on 2D surfaces in a 3D space (VR screens). We prototyped one such CVE to evaluate FoV frustrum visualisation within this collaboration scenario. We also implement a FoV visualisation generated from an average fixation map (AFM), therefore directly generated by users' gaze behaviour which we call Cone of Vision (CoV). Our approach to displaying the frustum visualisations is tailored for 2D surfaces in 3D space and allows for self-awareness of this visual cue. We evaluate CoV in the context of a general exploratory data analysis (EDA) with 10 pairs of participants. Our findings indicate that CoV is beneficial during shifts between independent and collaborative work and supports collaborative progression across the visualisation. Self-perception of the CoV improves visual attention coupling, reduces the number of times users watch the collaborator's avatars and offers a consistent representation of the shared reality.

Abstract:
<p>3D visualisations –including 3D scans and 3D reconstructions–designed as part of larger archaeology, history or cultural heritage projects are commonly shared with the public through online platforms that were not necessarily designed to host heritage representations and often fail to contextualize them. This paper seeks to evaluate whether five online platforms commonly used today to share 3D visualisations of heritage (Google Arts &amp; Culture, CyArk, 3DHOP, Sketchfab and game engines) offer features that facilitate their scientific rigour and community participation, based on guidelines from International Council on Monuments and Sites(ICOMOS)and United Nations Educational, Scientific, and Cultural Organization(UNESCO). The author starts by summarizing recommendations from 32 international guidelines that are relevant to the 3D visualization of heritage, condensing them into nine key criteria: multi-disciplinary teams, objective-driven methodology and tools, careful documentation, type of reconstruction and level of certainty, authenticity, alternative hypotheses, multiple historical periods, respectful use of the heritage, and community engagement. The author proceeds to review the platforms above comparing their features with these nine recommendations and concludes that, while there are currently available features that could help to elevate the scientific rigour of the 3D visualisations and their contextualization to the public, they are not mandatory and are seldom used. The paper finishes with a recommendation for an information package to support3D visualisations of heritage on public online platforms.</p><p><strong>Highlights:</strong></p><ul><li><p>Online platforms for the 3D visualization of heritage fail to disclose what type of reconstruction it is and its level of certainty, struggling to balance community engagement vs scientific rigour of their contents.</p></li><li><p>ICOMOS and UNESCO recommendations regarding heritage are loosely followed on the reviewed platforms, and supporting documentation is often lacking.</p></li><li><p>Scientific rigour on these platforms could be elevated with supporting textual fields to disclose further information about each visualisation.</p></li></ul>

Abstract:
In stakeholder participation workshops, digital and hard-copy maps, alongside other representation formats in 2D and 3D, are used extensively to support communication, spatial evaluation and interactive decision making processes. In this paper, we present a novel tool to enhance traditional map-based workshop activities using augmented reality. Augmented reality technology is gaining momentum as a tool for visualising environmental design choices in planning and design, and is used in a range of applications including stakeholder participation, design evaluation and flood risk communication. We demonstrate interactive and collaborative 3D cartographic visualisations which enable real-time multi-user exercises in landscape intervention design and flood visualisation.

Abstract:
Fingal’s Cave: an Audiovisual Experience is an immersive virtual reality application that combines 3D models, a narrative soundscape and interactive auralisation in a recreation of a visit to Fingal’s Cave. This research explores the importance of audio in heritage visualisations and its practical implementation. Fingal’s Cave is a sea cave on the Isle of Staffa off the west coast of Scotland revered for its extraordinary acoustics. Audio is extremely important in the history and culture of Fingal’s Cave and it has long been romanticised, inspiring countless folklore, art, poetry and music. The visualisation is designed to encourage viewers to become a part of the cultural narrative and explore the cave for themselves, move around and speak to hear their voice auralised as it would be inside the cave. This is the first time the acoustic characteristics of a heritage site have been included in a visualisation in this interactive manner. This paper reviews whether auralisation is effective and meaningful and supports a creative response to heritage sites. The impact of the visualisation in terms of engaging with communities of interest and in the field of audio in heritage visualisation is discussed. The research suggests it is necessary that audio be included in heritage visualisations to give a full and complete understanding of how people experience it.

Abstract:
Cesium (http://cesiumjs.org) is an open source, WebGL-based JavaScript library for virtual globes and 3D maps. It is an excellent tool for 3D thematic visualisations, but to use its full functionality it has to be feed with its own file format, CZML. Unfortunately, this format is not yet supported by any major GIS software. This paper intro- duces a plugin for QGIS, developed by the author, which facilitates the creation of CZML file for various types of visualisations. The usability of Cesium is also examined in various hardware/software environments.

Abstract:
<p class="VARKeywords">This article sets a framework for computer-based visualisations of cultural heritage sites. The project focuses on a workflow for a visualisation illustrated on a specific solution for the site of Çukuriçi Höyük, a tell settlement in Turkey. With the virtual presentation, an interdisciplinary research group tries to offer complex scientific results to the general public as well as to experts. The team utilised data acquisition and communication techniques, interpretative approaches, and dissemination methods. The three-dimensional (3D) outcome is based on a large amount of scientific data, usually available only via analogue or digital publications for a specialised audience. The work focused on constructed and personal authenticity to reach the viewer’s feelings. As an interpretative narrative, the daily lives of the inhabitants were selected. A communication plan was constructed, and a video animation with narration and a musical background was selected as the most appropriate communication tool. The movie was divided into four chapters <em>(Introduction, Neolithic Period, Chalcolithic Period </em>and <em>Early Bronze Age Period</em>). A separate webpage was designed to provide additional information when the video is viewed online. The webpage was divided into tabs that describe each chapter and three additional topics (<em>Visualisation Process, Further Reading, </em>and <em>Credits</em>). The video was shared in different settings, e.g. at public talks and on social media. The process resulted in a complex workflow that consists of several stages: data acquisition, first interpretation, 3D model creation, communication plan, second interpretation, 3D model adjustment, and dissemination output. Each stage of the workflow serves as an example to show the types of nodes these parts can include. The result is a flexible framework with predefined process stages, which can be re-used for similar projects.</p><p>Highlights:</p><ul><li><p>Computer-aided visualisations bring hidden cultural heritage to life –an individual outcome for Çukuriçi Höyük, a tell settlement in Turkey.</p></li><li><p>The interdisciplinary team combined data acquisition and communication techniques, interpretative approaches, and dissemination methods for achieving the best result.</p></li><li><p>Integrative framework optimises the information and communication potential of virtual visualisations with the help of pre-defined workflow stages.</p></li></ul>

Abstract:
This paper discusses on the integration application of using 3-Dimensional (3D) modelling program in order to teach architectural heritage design. The 3D program mentioned in this paper (3DStudioMax) was used in order to determine the ergonomic properties of traditional Malay furniture that were available inside the selected samples of Traditional Malay Houses (TMH). The anthropometric measurements of the Traditional Malays were calculated and transferred into 3D renderings in order to help visualise the interactions between the users and the furniture. The visualisations included recreation of the environment during which the users were carrying out their daily activities, all into 3D renderings. These visualisations also provided a look of how the furniture of the Traditional Malays were ergonomic towards their users. The samples used in this study consisted of technical drawings of TMH that were archived in the Center for the Study of Built Environment in the Malay Kingdom (KALAM) of Universiti Teknologi Malaysia (UTM). Results showed that the usage of the 3D program helps to give a better understanding of architectural heritage design by providing a visual aid in summarising elements that were no longer available within the environments during site visits.

Abstract:
Coastal geomorphologists and engineers worldwide are increasingly facing the non-trivial challenge of visualising and communicating mesoscale modelling assumptions, uncertainties and outcomes to both coastal specialists and decision-makers. Visualisation of simulation outcomes is a non-trivial problem because the more abstract scientific visualisation techniques favoured by specialists for data exploration and hypothesis-testing are not always as successful at engaging decision-makers and planners. In this paper, we show how the risk of simulation model outcomes becoming disconnected from more realistic visualisations of model outcomes can be minimised by using the Coastal Modelling Environment (CoastalME). CoastalME is a modelling framework for coastal mesoscale morphological modelling that can achieve close linkages between the scientific model abstractions, in the form of lines, areas and volumes, and the 3D representation of topographic and bathymetric surfaces and shallow sub-surface sediment composition. We propose and illustrate through the study case of Happisburgh (eastern England, UK), a transparent methodology to merge the required variety of data types and formats into a 3D-thickness model that is used to initialise a simulation. We conclude by highlighting some of the barriers to the adoption of the methodology proposed.

Abstract:
Sustainable decision making for strategic planning is a challenging process: requiring an understanding of the complex interactions among environmental, economic and social factors. Commonly, such decisions are dominated by economic factors hence there is a need for a framework that supports inclusive decision making throughout all stages of urban and rural planning projects. Towards this the authors have developed the Sustainable City Visualization Tool (S-CITY VT) which comprises 1) indicators (these provide the basis for assessment and monitoring of sustainability) selected according to scale and development 2) modelling techniques that provide indicator values, as not all of the indicators can be measured, and allows spatio-temporal prediction of indicators 3) Interactive 3D visualisation techniques to facilitate effective communication with a wide range of stakeholders. The sustainability modelling and 3D visualisations are shown to have the potential to enhance community engagement within the planning process thus enhancing public acceptance and participation within the urban or rural development project.

Abstract:
The overarching aim of this paper is to enhance the visualisations and classifications of airborne remote sensing data for remote forest surveys. A new open source tool is presented for aligning hyperspectral and full-waveform LiDAR data. The tool produces coloured polygon representations of the scanned areas and aligned metrics from both datasets. Using data provided by NERC ARSF, tree coverage maps are generated and projected into the polygons. The 3D polygon meshes show well-separated structures and are suitable for direct rendering with commodity 3D-accelerated hardware allowing smooth visualisation. The intensity profile of each wave sample is accumulated into a 3D discrete density volume building a 3D representation of the scanned area. The 3D volume is then polygonised using the Marching Cubes algorithm. Further, three user-defined bands from the hyperspectral images are projected into the polygon mesh as RGB colours. Regarding the classifications of full-waveform LiDAR data, previous work used extraction of point clouds while this paper introduces a new approach of deriving information from the 3D volume representation and the hyperspectral data. We generate aligned metrics of multiple resolutions, including the standard deviation of the hyperspectral bands and width of the reflected waveform derived from the volume. Tree coverage maps are then generated using a Bayesian probabilistic model and due to the combination of the data, higher accuracy classification results are expected.

<p><strong>Extended Abstract:</strong></p><p>We present a methodological approach for the representation, visualisation and analysis of three-dimensional (3D) models of meaningful details in stone reliefs provided by digital documentation tools and subsequent processing. For this aim, anthropomorphous shapes engraved on a flat stone slab found in Sierra de Fontcalent (Alicante) are studied. The object under consideration was located near two archaeological sites, Cova del Fum–a cave with presence of the Chalcolithic material (López, 2010)–and the archaeological site of Fontcalent, with remains from different phases of occupation spanning from 7th-6thBC to the 20thcentury (Ximénez, 2012).</p><p>In the last few years, the use of digital tools provided by new technologies and software development has left traditional work methodology behind (De Reu et al., 2014)while enabling the development of new approaches to both minimise heritage alteration and provide objective and accurate information (Lopez-Menchero, Marchante, Vincent, Cárdenas, &amp; Onrubia, 2017). 3D documentation allows recording of cultural heritage at a reasonable cost with precision and quality through digital photography and SfM (Structure from Motion) photogrammetry with specialised software (De Reu et al., 2013).</p><p>In this project, recording and documentation with digital photography and automated photogrammetric techniques are applied to the Fontcalent stone slab for its digitisation and subsequent 3D representation. From the resulting model, a two-folded line of study is obtained. On the one hand, a Digital Elevation Model (DEM) is generated to study the microtopographies of the stone with geographic analysis techniques provided by Geographic Information Systems (GIS) from different lighting conditions and surface reflections, which are calculated by hillshading or LRM (Local Relief Model) for the interpretation of the object (Carrero-Pazos, Vilas, Romaní, &amp; Rodríguez, 2014;Gawior, Rutkiewicz, Malik &amp; Wistuba, 2017).On the other hand, from both the 3D model and the point cloud, the study is completed with the application of the methods of analysis and visualisation based on the Morphological Residue Model (MRM) which stands out every single detail of the surface morphology of the object (Caninas, Pires, Henriques, &amp; Chambino, 2016;Correia, Pires, &amp; Sousa, 2014). Further visualisations are based on Reflectance Transformation Imaging (RTI) which provides different shadows and reflections over the object from the application of a multidirectional illumination (Happa et al., 2010; Malzbender, Gelb, Wolters, &amp; Zuckerman, 2000; Mudge et al., 2010).</p><p>The results thus obtained of the Fontcalent stone slab allow us to visualise several characteristic elements. The anthropomorphous figure awaking interest is also combined with the figure resulting from different visualisations applied with GIS techniques which may resemble a zoomorph. The use of visualisation techniques shown in this study has been fundamental in order to recognise the latter element. The composition reveals a zigzag line already appreciated before the study so that it is interesting to check if visualisations based on GIS techniques are able to highlight it though being shallow incisions. In our experience regarding this study, visualisation by using the hillshading technique shows a greater level of 3D detail than that provided by the application of the sky-view factor technique which offers a flattering view. However, the former technique may occasionally show shadows which hide other details, unlike the latter technique which plots the entire slab surface illuminated while differentiating the associated microtopography on the basis of its marks. The use of shaders in combination with hillshading and particularly combined with high pass filtering, contributes to improving the visualisation and accuracy of shadowed areas. As a result, we conclude that the results obtained in this work by lighting techniques with GIS add a greater level of detail in comparison to those provided by the mesh or the point cloud.</p><p>The study of the Fontcalent stone slab paves the way for two working hypotheses to be developed: on the one hand, its anthropological origin possibly related to the Chalcolithic, and on the other hand, its study as natural geological formations with ichnofossils.</p><p>The digitisation of cultural heritage with available 3D technologies should be a mandatory requirement when facing any study, analysis or intervention. With the current development of such techniques, we have verified their contribution to fundamental characteristics in the corresponding stages of visualisation and study. Thus, the proposed methodology is presented as an accurate and complete alternative for the study and analysis of the existing cultural heritage, and opens new ways for the revision, reinterpretation and revaluation of the previously evaluated heritage through traditional techniques.</p>

Abstract:
Planning and management of urban space that involves the local community the process is key to optimal management of the surroundings, in line with social needs. Social isolation imposed because of the COVID-19 pandemic considerably reduces the possibility of conducting public consultations. This study hypothesized that such consultations can be carried out using new visualisation technologies in the virtual reality (VR) area. Owing to the development of new technologies, innovative services can be created which make it easier for recipients to absorb new content. To this end, the ArchitektVR application was developed, which uses enhanced reality for public consultations concerning planned land development. 3D visualisation with VR enables the presentation of various aspects of area development in a clear form, understandable to an average user with no specialist qualifications. It facilitates the presentation and creation of multiple variants/scenarios for the future shape of the area. The research assumptions were tested for a disused area of a water body. According to preliminary tests, the use of virtual reality could provide a new form of communication between decision-makers and citizens. Effective and easy-to-understand visualisations might provide encouragement to participate in local matters and enable citizens to make better decisions. 3D visualisation enabled concerned individuals to assess the potential development of a selected area fragment without an in-person visit, either in the field or to an office. This is of particular importance in relation to the COVID-19 pandemic and sanitary restrictions.

The secondary objective is to increase the tourism potential and attractiveness of the various historical sites and the studied region. The comprehensive methodical processing of documents and the creation of 3D models of objects and other digital visualisation requires not only high-quality programmers and graphic artists, but especially scientists who create historically-relevant descriptive texts, real schemes, and historically acceptable models that can be computer-processed, visualised, and used as an effective tool for the development of tourism. Research and follow-up activities require an interdisciplinary approach, i.e. the cooperation of experts from various disciplines. The research processed in this study points out that even simple, now widely available modern means of communication, such as websites, can be effectively used for the promotion and publicity of this type of attraction. High-quality 3D models and visualisations of buildings and specific destinations, or cultural and technical monuments, can thus become available to tourists also outside museums. This paper introduces the opportunities of digital presentation of preserved, partially defunct and, especially, completely defunct historical buildings and sites that are often almost unknown to tourists. In many cases, only their shells or foundations remain. In terms of cultural heritage conservation and monument protection, these sites are often among the most important religious buildings from various historical periods. This study focuses on the Middle Ages and locations in Slovakia (former Hungary), and presents a methodology that is generally applicable for the research and visualisation of any similar cultural sites, and thus opening up their potential to tourists.

Abstract:
Since a few years, structure-from-motion and multi-view stereo pipelines have become omnipresent in the cultural heritage domain. The fact that such Image-Based Modelling (IBM) approaches are capable of providing a photo-realistic texture along the threedimensional (3D) digital surface geometry is often considered a unique selling point, certainly for those cases that aim for a visually pleasing result. However, this texture can very often also obscure the underlying geometrical details of the surface, making it very hard to assess the morphological features of the digitised artefact or scene. Instead of constantly switching between the textured and untextured version of the 3D surface model, this paper presents a new method to generate a morphology-enhanced colour texture for the 3D polymesh. The presented approach tries to overcome this switching between objects visualisations by fusing the original colour texture data with a specific depiction of the surface normals. Whether applied to the original 3D surface model or a lowresolution derivative, this newly generated texture does not solely convey the colours in a proper way but also enhances the smalland large-scale spatial and morphological features that are hard or impossible to perceive in the original textured model. In addition, the technique is very useful for low-end 3D viewers, since no additional memory and computing capacity are needed to convey relief details properly. Apart from simple visualisation purposes, the textured 3D models are now also better suited for on-surface interpretative mapping and the generation of line drawings.

Abstract:
Photography and photogrammetry have recently become among the most widespread and preferred visualisation methods for the representation of small objects and artefacts. People want to see the past, not only know about it; and the ability to visualise objects into virtually realistic representations is fundamental for researchers, students and educators. Here, we present two new methods, the ‘Small Object and Artefact Photography’ (‘SOAP’) and the ‘High Resolution “DIY” Photogrammetry’ (‘HRP’) protocols. The ‘SOAP’ protocol involves the photographic application of modern digital techniques for the representation of any small object. The ‘HRP’ protocol involves the photographic capturing, digital reconstruction and three-dimensional representation of small objects. These protocols follow optimised step-by-step explanations for the production of high-resolution two- and three-dimensional object imaging, achievable with minimal practice and access to basic equipment and softwares. These methods were developed to allow anyone to easily and inexpensively produce high-quality images and models for any use, from simple graphic visualisations to complex analytical, statistical and spatial analyses.

Abstract:
Purpose The purpose of this paper is to develop data visualisation proof of concept prototypes that will enable the Curtin University Library team to explore its users’ information-seeking behaviour and collection use online by analysing the library’s EZproxy logs. Design/methodology/approach Curtin Library’s EZproxy log file data from 2013 to 2017 is used to develop the data visualisation prototypes using Unity3D software. Findings Two visualisation prototypes from the EZproxy data set are developed. The first, “Global Visualisation of Curtin Research Activity”, uses a geographical map of the world as a platform to show where each research request comes from, the time each is made and the file size of the request. The second prototype, “Database Usage Visualisation”, shows the use of the library’s various subscription databases by staff and students daily, over a month in April 2017. Research limitations/implications The paper has following limitations: working to a tight timeline of ten weeks; time taken to cleanse noise data; and requirements for storing and hosting the voluminous data sets. Practical implications The prototypes provide visual evidence of the use of Curtin Library’s digital resources at any time and from anywhere by its users, demonstrating the demand for the library’s online service offerings. These prototype evidence-based data visualisations empower the library to communicate in a compelling and interesting way how its services and subscriptions support Curtin University’s missions. Originality/value The paper provides innovative approaches to create immersive 3D data visualisation prototypes to make sense of complex EZproxy data sets.

Abstract:
AbstractEvidence presented within a courtroom should be clear so that the members of the jury can understand it. The presentation of distressing images, such as human remains, can have a negative effect on the jury since photographic images may evoke emotional responses. Therefore, it is important to understand how other visual mediums may improve comprehension, bias, or distress individuals. For this study, 91 individuals were randomly assigned one of three visual evidence formats in a mock courtroom exercise. These included photographs, 3D visualisations, or a 3D-printed model. The results show that the use of 3D imaging improves the juror’s understanding of technical language used within a courtroom, which in turn better informs the juror’s in their decision-making.

Abstract:
This paper describes a study of the use of immersive Virtual reality technologies in the design of a new hospital. It uses Schön’s concept of reflective practice and video-based methods to analyse the ways design teams approach and employ a full scale 3D immersive environment – a CAVE – in collaborative design work. The analysis describes four themes relating to reflective practice occurring in the setting: orienting to the CAVE technology itself, orienting to the representation of the specific design within the CAVE, activities accounting for, or exploring alternatives within the design for the use and users of the space, and more strategic interactions around how to best represent the design and model to the client within the CAVE setting. The analysis also reveals some unique aspects of design work in this environment. Perhaps most significantly, rather than enhancing or adding to an existing understanding of design through paper based or non-immersive digital representations, it is often acting to challenge or surprise the participants as they experience the immersive, full scale version of their own design.

Abstract:
With urban design, it is becoming increasingly important to both visualise spatial changes and quantify the effect of these changes on the local microclimate: the former often for public consultation and the latter to develop landscapes that provide resilience to warmer weather thus reducing the urban heat island effect. It is possible to automatically construct 3D landscape models from vector site plans and height data sources through procedural generation. However, the generation of the inputs for microclimate models remains a time consuming process even though 3D visualisations or site plans may already exist. In this paper, a method to link procedurally generated 3D landscape models to microclimate simulations is demonstrated. Using this method, a case study is presented that allows initial calibration of the model and then several distinct alterations in the base design are tested alongside the variation in weather conditions looking forward to 2080. Finally, graphics card shaders are used to incorporate the temperature data within the interactive 3D procedural models, allowing both real-time manipulation of view point and simulation time.

Abstract:
In physics we often encounter high-dimensional data, in the form of multivariate measurements or of models with multiple free parameters. The information encoded is increasingly explored using machine learning, but is not typically explored visually. The barrier tends to be visualising beyond 3D, but systematic approaches for this exist in the statistics literature. I use examples from particle and astrophysics to show how we can use the “grand tour” for such multidimensional visualisations, for example to explore grouping in high dimension and for visual identification of multivariate outliers. I then discuss the idea of projection pursuit, i.e. searching the high-dimensional space for “interesting” low dimensional projections, and illustrate how we can detect complex associations between multiple parameters.

Abstract:
Abstract. Three-dimensional (3D) visualisations of geospatial data have become very popular in the last years. Various applications and tools are based on interactive 3D geovisualisations. However, the user aspects of these 3D geovisualisations are not yet fully understood. While several studies have focused on how users work with these 3D geovisualisations, only few studies focus directly on interactive 3D geovisualisations and employ usability research methods like screen logging. This method enables the objective recording of movement in 3D virtual environments and of user interactions in general. Therefore, we created a web-based research tool: a 3D Movement and Interaction Recorder (3DmoveR). This tool is based on the user logging method, combined with a digital questionnaire and practical spatial tasks. The design and implementation of this tool follow the spiral model, and its current version is 2.0. It is implemented using open web technologies such as PHP, JavaScript, and the Three.js library. After building this tool, we verified it through load testing and a simple pilot test verifying accessibility. We continued to describe the first deployment of 3DmoveR 2.0 in a real user study. The future modifications and applications of 3DmoveR 2.0 are discussed in the conclusion section. Attention was paid to future deployment during user testing outside controlled (laboratory) conditions.

Abstract:
Abstract 3D data captured from archaeological excavations are frequently left to speak for themselves. 3D models of objects are uploaded to online viewing platforms, the tops or bottoms of surfaces are visualised in 2.5D, or both are reduced to 2D representations. Representations of excavation units, in particular, often remain incompletely processed as raw surface outputs, unable to be considered individual entities that represent the individual, volumetric units of excavation. Visualisations of such surfaces, whether as point clouds or meshes, are commonly viewed as an end result in and of themselves, when they could be considered the beginning of a fully volumetric way of recording and understanding the 3D archaeological record. In describing the creation of an archaeologically focused recording routine and a 3D-focused data processing workflow, this article provides the means to fill the void between excavation-unit surfaces, thereby producing an individual volumetric entity that corresponds to each excavation unit. Drawing on datasets from the Kaymakçı Archaeological Project (KAP) in western Turkey, the article shows the potential for programmatic creation of volumetric contextual units from 2D point cloud datasets, opening a world of possibilities and challenges for the development of a truly 3D archaeological practice.

<p class="VARAbstract">A key issue in the study of cultural assets is theiroften fragmentary condition. This causes serious problems and questions regarding theirstudy and presentation. Pottery fragments are the most numerous findings in every excavation. Furthermore, pottery plays an essential role for the reconstruction of the past, since it providesinformation for all aspects of life (private, public, religion, death, economy, society, trade,etc.). Therefore,a thorough study and presentation of pottery fragments contribute to a better knowledge of the past.The focus of this work is the visualisation of an ancient Greek drinking vase, a kantharos, which was unearthed during the excavations at the settlement of Karabournaki (ancient Therme) in the area of Thessaloniki (Greece). It dates to the Archaic period (7th-6thc. B.C.) and it was found in fragments among the settlement's architectural remains. The vase is of great archaeological significance due to its peculiarities in terms of shape, decoration and function. Therefore,its digital completion and 3D reconstruction willcontribute to its betterstudy and scholarly publication along with a general contribution to the field of pottery studies.We discuss on the 3D digitisation of the kantharosfragments that werebased onStructure from Motion/Multiple View Stereovision (SfM/MVS) and a custom automated data collection system. A detailed description of the digitisation pipeline is given along with details related to the quality of the 3D digital replicas of the sherds. Furthermore, we presentour manual virtual reassembly and reconstruction pipelineof the kantharosby describing the challenges, issues and ambiguities discovered while analysing the geometrical features of each sherd. A number of photorealistic reconstruction visualisations of the artefact are presented in order to question the applicability of the solution for the actual reconstruction</p>

Abstract:
Advancements in the computing realm have assisted the Architecture, Engineering, and Construction (AEC) industry to progress significantly by automating several design tasks and activities. Building Information Modelling (BIM) authoring tools have played a significant role in automating design tasks and reducing the efforts required by the designer in redundant, repetitive or production-oriented activities. This paper explores one such approach that, with the help of BIM authoring tool and its Application Programming Interface (API), reduces the efforts expended on formwork design for concrete structures. The paper utilises the concept of using BIM data as input to compute the quantity of formwork, and generate visualisations and schedule of formwork. The developed approach first takes data input from semantic BIM to the API environment for computation and design of formwork systems, which is then placed within the BIM model, to generate visualisation and prepare schedules. The research work utilises a structural concrete wall as an example to demonstrate the presented approach. The approach will be influential in streamlining the formwork design process in the BIM environment and reducing efforts required by the designer and the planning engineer. Since the formwork elements are generated as 3-Dimensional (3D) solids and smart BIM elements, the generated model of formwork can be used for resolving clashes, scheduling, and resource planning.

Abstract:
Under suitable conditions, ground-penetrating radar (GPR) measurements harbour great potential for the non-invasive mapping and three-dimensional investigation of buried archaeological remains. Current GPR data visualisations almost exclusively focus on the imaging of GPR reflection amplitudes. Ideally, the resulting amplitude maps show subsurface structures of archaeological interest in plan view. However, there exist situations in which, despite the presence of buried archaeological remains, hardly any corresponding anomalies can be observed in the GPR time- or depth-slice amplitude images. Following the promising examples set by seismic attribute analysis in the field of exploration seismology, it should be possible to exploit other attributes than merely amplitude values for the enhanced imaging of subsurface structures expressed in GPR data. Coherence is the seismic attribute that is a measure for the discontinuity between adjacent traces in post-stack seismic data volumes. Seismic coherence analysis is directly transferable to common high-resolution 3D GPR data sets. We demonstrate, how under the right circumstances, trace discontinuity analysis can substantially enhance the imaging of structural information contained in GPR data. In certain cases, considerably improved data visualisations are achievable, facilitating subsequent data interpretation. We present GPR trace coherence imaging examples taken from extensive, high-resolution archaeological prospection GPR data sets.

AbstractA system setup for measurements of acoustic field, together with the results of 3D visualisations of acoustic energy flow are presented in the paper. Spatial sampling of the field is performed by a Cartesian robot. Automatization of the measurement process is achieved with the use of a specialized control system. The method is based on measuring the sound pressure (scalar) and particle velocity(vector) quantities. The aim of the system is to collect data with a high precision and repeatability. The system is employed for measurements of acoustic energy flow in the proximity of an artificial head in an anechoic chamber. In the measurement setup an algorithm for generation of the probe movement path is included. The algorithm finds the optimum path of the robot movement, taking into account a given 3D object shape present in the measurement space. The results are presented for two cases, first without any obstacle and the other - with an artificial head in the sound field.

Abstract:
Archaeological excavation is a demolishing process. Rather few elements outlast extractive operations. Therefore, it is hard to visualise the precise location of unearthed finds at a previously excavated research area. Here, we present a mixed reality environment that displays in situ 3D models of features that were formerly extracted and recorded with 3D coordinates during unearthing operations. We created a tablet application that allows the user to view the position, orientation and dimensions of every recorded find while freely moving around the archaeological site with the device. To anchor the model, we used physical landmarks left at the excavation. A series of customised forms were created to show (onscreen) the different types of features by superimposing them over the terrain as perceived by the tablet camera. The application permits zooming-in, zooming-out, querying for specific artefacts and reading metadata associated with the archaeological elements. When at the office, our environment enables accurate visualisations of the 3D geometry concerning previously unearthed features and their spatial relationships. The application operates using the Swift programming language, Python scripts and ARKit technology. We present here an example of its use at Les Cottés, France, a palaeolithic site where thousands of artefacts are excavated out of six superimposed layers with a complex conformation.

Abstract:
Along with the development of three-dimensional computer graphics, methods of collecting and making 3D spatial data available became a significant issue covering the interoperability of data derived from multiple sources. Between 2006 and 2008, the Open Geospatial Consortium designed a CityGML model as a proposal for a uniform classification, graphic representation, construction, and storage of 3D objects. A considerable part of three-dimensional visualisations, now gaining popularity, make use of solutions based on the CityGML standard, with which they are compatible to various degrees. The survey involved a comprehensive analysis of sixteen generally accessible 3D geoportals of cities in Europe, Asia, and North America in terms of their broad-sense functionality as well as technical and thematic compatibility with the assumptions of CityGML standards. The level of realisation of various features related to the provided spatial data services was evaluated, taking into account elements that the present-day world literature deems to be particularly desirable. The analysis resulted in an elaborate ranking of websites according to 21 criteria. The most common objects and features of the analysed geoportals were also detailed. In addition, the authors presented several solutions to improve the quality of three-dimensional geoportals of cities by implementing external data from various sources.

Abstract:
The Barrow Sub-basin and Exmouth Plateau, of Australia’s North West Shelf, contain Australia’s largest gas reserves, underpinning the three major LNG facilities, including Gorgon, Wheatstone and Pluto. In addition, there remains significant near-field exploration potential such as the Sasanof prospect. While there is full 3D seismic coverage in the basin, the existing 3D surveys are of different vintages covering only parts of the basin with diverse acquisition and processing parameters. Multi-Client Resources has produced an extensive 3D seismic reprocessing project (BEX-MC3D) incorporating 23 legacy 3D surveys to provide a seamless 25 570 km2 3D dataset. The BEX-MC3D was processed from field tape through DUG Technology’s advanced Broadband PreSDM processing sequence with Full Waveform Inversion (FWI) imaging. The BEX-MC3D provides one continuous superlative 3D dataset covering almost the entire Barrow Sub-basin and the Exmouth Plateau. Major geological surfaces corresponding to key tectonic events from overburden to reservoirs have been interpreted from the BEX-MC3D Priority area in the current study. These high-fidelity imaged surfaces form a basin-wide framework for: (1) rapid exploration lead and prospect identification through the creation of trap and reservoir visualisations; (2) improved reservoir connectivity analysis and modelling of producing and discovered fields to support better reservoir management and field development decisions; and (3) improved understanding of basin-burial history for reservoir quality and geo-mechanical property prediction. This paper will present and discuss major geological surfaces in the context of future exploration lead/prospect identification, reservoir characterisation for field development and management, and improving overall understanding of the basin history.

Abstract This paper presents a proof-of-concept intervention monitoring and outcome assessment tool for thermal ablative strategies like microwave ablation of hepatic tumours. For this purpose, simulated 3D+t temperature maps of the ablation progress are combined with liver MR imaging, as well as corresponding segmentations of the lesion and other relevant anatomical structures. The proposed tool mainly consists of a monitoring and validation part, each comprising 2D and 3D visualisations and various modifiable settings. With the aid of the monitoring features, the heat propagation during the ablation progress could be visually tracked, while the validation part of the tool provides the radiologist with comprehensible and detailed feedback to assess the treatment result. Hence, it could enable an immediate validation of the ablation progress and support interventional decision-making. For evaluation purposes, we used an exemplary patient case to demonstrate the benefits of the proposed prototype. This tool could represent a crucial step towards a suitable computerassisted and more accurate workflow of thermal ablations, with benefits for both, patients and radiologists.

Abstract:
With the applications of new construction technologies and design ideas, innovative construction methods and architectural designs promote overall productivity and enrich architectural impressions. However, faced with the contradictions between construction efficiency, project benefits, and sustainability, together with the dynamically variable social demands and monotonous design of current temporary light steel structures, a new type of growable light steel structure with parameterisable and assembled architectural units is proposed. Besides, a fast-assembled track foundation that can be detachable and recycled is adopted. Both can promote the growth of light steel units. To be specific, its architectural spaces can be extended and contracted, and the structural form and service space can be adjusted by the reorganisation and optimisation of unit arrangements. Meanwhile, due to the advantages of information integrations and 3D visualisations of BIM technology, a BIM-based design and construction method of growable light steel structures is studied. Based on the arrangements of track and parametrically transformed light steel units, this study expands the architectural forms of light steel structures. It explores their respective applications in practical architectural design to solve current shortages of land resources, properly respond to variable building environments, simultaneously enrich the design schemes of current light steel structures, improve the utilisation rate of structural spaces, and enhance the aesthetic sensations of buildings.

Abstract:
AbstractWe propose three novel digital biomarkers for the longitudinal performance monitoring and movement evaluation of hemiparetic patients, e.g. after stroke. We devised convergence points (CP) for the bilateral walking analysis based on gait parameters, e.g. stride duration using regression- modelling to estimate similarity between body sides. The physical activity (PA) was devised to evaluate the energy expenditure of all extremities during training and free-living. The functional range of motion (fROM) is a digital biomarker to quantify the upper arm reaching ability, represented in 3D visualisations. In this work, we detail CP, PA, and fROM to derive rehabilitation insights for personalising therapies. We evaluated the proposed digital biomarkers in a clinical observation study with 11 patients after stroke during their rehabilitation including therapy and self-paced daily routines.
