In fact, beyond the exploration for education and entertainment purposes, the employment of three-dimensional (3D) reality-based and computer-based models and environments seems to be very promising for performance assessment and risk management as well. Particularly, in order to develop and validate smart, low-cost and user-friendly tools, which might apply even in cases of limited time and budget, the present paper is going to propose a methodological workflow based on thematic virtual tours of 360° scenes, which integrate a variety of informative contents and digital products as external hotspots/switches. The VR tours, where 3D models might play a key role for an accurate representation of relevant parts and/or analytical elaboration of further data, are conceived as flexible and scalable solutions, supporting users, technicians and authorities through remote access, diagnosis of the state of conservation and communication of safety measures. The application of the proposed methods and techniques to a representative case study, the Norman-Swabian Castle of Gioia del Colle (Ba), South Italy, is presented in order to illustrate the achievable results and highlight the benefit of innovative “digital” solutions for data collection, storage and communication, compared to the traditional “analogical” practices. In detail, a Web-GIS platform, developed within a previous research project, is integrated with direct links to three thematic virtual tours that provide added contents for inclusive dissemination (timeline schemes, aerial views, 3D sculptural and architectural details), performance assessment (diagnostic reports, decay maps, 3D reconstructions of technical components) and risk management (exit signs, help instructions, warnings). Thus, the VR tours, while documenting realistically the state of the site, might act as host environments of digital products, at increasing complexity, all displayed according to an intuitive and accessible communication approach.Highlights:• Virtual tours of 360° scenes, linking thematic digital contents, are proposed as intuitive and versatile tools for smart documentation, conservation and protection of historical buildings.• The role of 3D reality-based and computer-based models is discussed toward their integration and correlation within thematic virtual tours of 360° scenes.• The potential of immersive environments for sharing knowledge about conservation issues and training users on safety measures in historic buildings is underlined.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48785180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The anchor stock had some interesting characteristics for this research. On the one hand, from the point of view of conservation and restoration, due to the alterations it presented. On the other hand, from a historical and archaeological point of view, it showed signs of reliefs on its surface hidden under the alteration products. The removal of the different layers of alteration that covered the surface during conservation and restoration treatments revealed an unpublished iconographic and epigraphic programme, as well as possible marks of use and manufacture. The poor state of conservation of the original surface made it impossible to visualise the details as a whole, so we applied photogrammetric methods, and subsequently processed models using various GIS analysis and point cloud processing softwares.Two photogrammetric models (in Agisoft PhotoScan) were made to document the trap in general: one prior to the conservation and restoration process; and a second three-dimensional (3D) model once the surface had been cleaned. The purpose of the second model was to visualise the reliefs programme in general, as well as the different surface details. The first complete 3D model of the object was used to perform a virtual reconstruction of the anchor including the elements that did not preserve, using a 3D modelling program (Blender).Nine areas of the stock surface were selected for the analyses of the various iconographic and epigraphic features, which were documented and processed in Agisoft PhotoScan. The Digital Elevation Model (DEM) and point cloud models were then processed with different analyses tools in Geographic Information System (GIS) (such as QGIS) and point cloud processing software (CloudCompare). Our results document a piece of highly interesting information from its surface consisting of reliefs of four dolphins; at least four rectangular stamps: two of them with possible inscriptions, and an anthropomorphic figure. Thanks to the comparative data, we conclude that the four dolphins were made with the same stamp during the stock manufacturing process. Further, we were able to reconstruct the dolphin stamp, partially preserved in each of the reliefs, by unifying the 3D models, thus revealing the original set. This system of stamping by means of reusable dies is well known in other elements such as amphorae but has not been studied in the specific case of lead traps.In the case of the epigraphic elements, the 3D documentation methodology revealed numerous micro-surface details, not visible under conventional documentation techniques, which could help specialists to interpret these inscriptions.

The municipality commissioned the research to support the preliminary design of the preservation plan. The first digitisation level has been started from the richness of surveying data acquired from static and dynamic terrestrial laser scanning (TLS), and photogrammetry, overcoming challenging constraints due to the scaffolding covering the surfaces. The geometric survey allowed authors to acquire massively geometric and material information supporting the three-dimensional (3D) volume stratigraphic and the creation of the Heritage Building Information Modelling (HBIM). The paper proposes a shift from the Geographic Information System (GIS)-based analysis of the materials toward spatial HBIM management. Building Archaeology is turned into HBIM 3D volume stratigraphy, overcoming the bidimensional (2D) surface mapping, in favour of a 3D understanding of direct and indirect sources. Material mapping is added to HBIM 3D volume stratigraphy, and each stratigraphic unit (SU) has its proprieties. The 3D volume stratigraphic database has been designed to collect the data on the unit detection at three levels (direct sources data collection, indirect data documentation, the relation among the BIM object elements). A common data environment (CDE) has been set up to share the 3D volume informative models that can be accessed, and all the information gathered. The knowledge transfer using the eXtended reality (XR) has been devoted to the citizen and tourist fruition, enhancing the comprehension of difficult concepts like the SUs to support a better critical 3D reconstruction. It includes the phases of construction across time-lapse documentation that validates related information within the building archaeology informative models leaving spaces to the uncertainty and documenting the relationship established so far thanks to the direct and indirect sources. The result obtained is a live digital twin that can be continuously updated, which justifies the costs and time demanding of HBIM despite 2D drawings.Highlights: • 3D survey and scan-to-HBIM process for the creation of a digital twin were oriented to the preliminary design of the preservation plan of the church of St. Francesco in Arquata del Tronto (Italy). • Stratigraphy is investigated and oriented towards a digitisation process to share different levels of knowledge through new forms of digital-sharing such as Common Data Environment (CDE) and cloud-based BIM platform. • eXtended reality (XR) is the final tool to reach new levels of communication and a wider audience characterised by experts in the construction sector and virtual and non-expert tourists.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45341046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regrettably, research has been dominated by biased and racial interpretations of both bioarchaeological and cultural evidence. When scientific racism and craniometric studies were rejected, studies of the Canarian indigenous skulls variability was also abandoned without replies. However, digital technologies and virtual sciences allow us to improve research and re-evaluate old paradigms. In this work, we present a digitalisation project aiming to construct a virtual database of the indigenous Canarian skulls, using a simple method of digitalisation that is very suitable to deal with large collections- The procedure, involving a  portable 3D structured light scanner has allowed us to digitally reproduce more than 400 skulls stored at  Museo Canario. This work offers a wide variety of possibilities for archaeology and anthropology. The versatility of 3D digital models enables the generation of interactive documentation, educational material for digital conservation and dissemination purposes. Indeed, 3D models are easily shared and can be displayed over diverse web-based repositories and online platforms and so, creating virtual online museums. We have created a profile in Sketchfab (https://sketchfab.com/craniacanaria2.0) where we intend to upload gradually the complete virtual collection of skulls we have realised. Moreover, digital skulls can serve as research objects. We discuss the advantages of studying 3D objects in a computerised environment, which includes traditional anthropometric studies (linear measurements and angles) but also 3D geometric morphometric approaches. In fact, in future studies, we will apply 3D geometric morphometrics for reassessing skull variation of ancient Canarians going beyond old paradigms and taking into account the latest advances in archaeology, anthropology and genetics in Canarian research. Highlights:- El Museo Canario stores an exceptional human skull collection that has served as the basis for numerous studies seeking to reveal the origin and chronology of the indigenous population.- This study presents an easy methodology for obtaining digital imagery using a 3D surface scanner, which allows constructing a virtual skull collection comprising more than 400 individuals.- Virtual 3D models have numerous advantages and applications in anthropology and archaeology, not only improving research but also permitting the re-evaluation of old paradigms.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42997538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This project is using new and unique tools for the research, documentation, interpretation and dissemination of this important prehistoric site. The incorporation of advanced technological tools in the field of archaeological and cultural heritage, such as digital documentation and virtual reality (VR), are creating new avenues for managing cultural legacies. Modern advances in 3D digitization and VR allow the application of these techniques on a wide range of cultural assets with different characteristics and chronologies, opening a broad spectrum of new possibilities in research, education, and public outreach. This is an expanding area of heritage management as it creates a positive impact on the economic, cultural and social activities of local communities and regions. Because of these positive impacts, more and more stakeholders such as institutions, administrations, and heritage organisations are taking an active interest in this sector of technological development. In the case of the Motilla del Azuer archaeological site, the digitization and virtualization work undertaken, along with other dissemination activities, have provided critical products for the presentation, interpretation, and promotion of this monument.La Motilla del Azuer is one of the most unique archaeological sites in Spain. Dating from the Bronze Age, it is a fortification with a central plan, formed by three lines of concentric walls distributed around a central tower (Fig. 2). Inside, the labyrinthine shape of the access systems is remarkable, made up of narrow corridors, stairs, ramps... This defensive enclosure allowed the protection and control of essential products for the people of the Bronze Age. Its true uniqueness is that it encloses monumental water well more than 15 m deep.La Motilla del Azuer is open to the public and receives thousands of visitors each year. But for conservation reasons, the number of people who can access the site is highly controlled. Likewise, due to its defensive nature and its age, it is a space through which it is difficult to circulate, which makes it impossible for people with reduced mobility to visit. For these and other reasons, the Daimiel City Council in collaboration with the US non-profit entity Global Digital Heritage and the Spanish company Myou Software, has developed a project to digitize the archaeological site and make it accessible through an installed VR system, located permanently in the Daimiel Museum, the interpretation centre for the site (Fig. 10). This facility is designed to be used both by people in wheelchairs or with reduced mobility, as well as all visitors to the museum, and provides a realistic virtual tour of the site. To achieve this level of realism, a detailed 3D digitization of the site using photogrammetry, laser scanning, and 3D spherical photography was undertaken, and a VR","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70631835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sbrogiò","doi":"10.4995/var.2022.15319","DOIUrl":"https://doi.org/10.4995/var.2022.15319","url":null,"abstract":"The virtual reconstruction of ancient architecture aims at describing the ‘original’ elevation and volume of a disappeared building. The feeble archaeological traces, often limited to their foundations, left by houses impair the reinstating of their image, in contrast to that which is made possible by the massive structures of public buildings. A twofold problem arises when dealing with timber structures during a reconstruction procedure: at the local scale of the individual beam (e.g. joists or rafters), one must define a beam’s cross-section given its span; at the overall scale, the shape of a building results from that which its structures allowed it to have been. Therefore, this work proposes a procedure to deal with the ‘local’ problem, i.e. the definition of a beam’s cross-section from its span. To that end, a simplified, parametric structural model is required. The available bits of information are organized into inputs, parameters and outputs of the analytical problem by matching each information with a structural quantity (load, cross-section, spacing, etc.). Two mathematical relationships among them are proposed, which express two equally possible dimensioning criteria, based either on joists’ strength or deformability. It seems that the joist’s strength was the option for lightly loaded joists, as in roofs or tightly spaced floor frames; conversely, heavily loaded joists conformed to the deformability criterion. Both dimensioning procedures are translated into a visual algorithm in Grasshopper, a plugin for Rhinoceros modelling software, which enables the parametric definition of objects. Finally, the proposed procedure is tentatively applied to automatically reconstruct the floor and roof frames that belonged to the domus on top of the Sarno Baths in Pompeii. The algorithm automatically picked the dimensioning criterion in relation to each frame’s span and hypothesized loads and determined joists’ orientation and minimum cross-sections. The obtained floor frames, whose structural conditions are considered as sensible, will be adopted in the overall virtual reconstruction proposal of the ruins, also based on the analytical evaluation of masonry structures.Highlights:- Proposal of a structural model for the dimensioning of timber floor beams in domestic spaces based on archaeological and literature information.- Parametrical interpretation of the model in Grasshopper for Rhinoceros software and optimization analysis of the structural parameters involved.- Application of the model to the reconstruction of floor frames in a house in the Sarno Baths complex, Pompeii.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48744578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intensification of olive tree cultivation in the 18th century gave rise to the proliferation of these constructions throughout the town, which at one point was home to no less than 286 mills of this type. However, by the mid-20th century events surrounding the local olive groves caused many of them to fall into disuse. Nowadays, the mills present an advanced state of decay, to the extent that many of them have disappeared partly or completely. In view of the functional nature of these production units and the short space of time in which they were built, we decided to conduct a typological study aimed at identifying any common patterns in their design. The geometric and proportional relationships between their constituent parts obtained using digital information models (Geographic Information System (GIS), 3D point clouds and databases) enabled us to determine standard structures based on ranges of deduced values. The repetition of these patterns suggested that it would be useful to create a graphical database using a parameterised HBIM (Historic Building Information Modelling), which in turn facilitates the introduction of attributes associated with these mills from a dynamic database, therefore favouring interoperability in heritage management as a response to the critical situation of the mills today. At the same time, the correspondence in the relationships of proportionality between the mills analysed typologically and the model of a 16th-century mill, suggests that 18th-century mills were adapted to patterns developed in older presses.Highlights:- The typological study of the Écija (Seville) mills with beam and weight presses reveals common patterns in these preindustrial buildings.- The proportional relationships between their constituent parts obtained using digital information models enabled us to determine standard structures. - These patterns have similarly enabled us to generate a parameterised HBIM model as a standard graphical base for the historical mills in Écija.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43682456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fortification had a long history of warfare that ended with the Peninsular War (1808–1814), which turned it into ruins. In 2002, the Roses city council planned an ambitious architectural intervention to recover the fortification. The works restored the overall exterior volumetry, with current construction materials. The large interior spaces resulting from the intervention had little in common with the original structures. Starting in 2016, the museum projected to open the fort to the public. The strategy focused on 3D works, which were used to plan museographic proposals and to make an interior space understandable, with an aspect very distant from that of the original construction. It entailed extensive fieldwork analyzing the sources and structural remains that were preserved and surmising the possible architectural solutions the fortress originally contained. Based on evidence and hypotheses, the group carried out a reconstruction from virtual archeology, and it developed a didactic iconography to explain the artifact to a broad spectrum of visitors and students. This iconography was applied on the panels, in the scenography and audiovisuals of the museum, and in the dissemination materials. The museography was implemented between 2019 and 2021. Considering the variables and comprehensive needs for a wide range of users and visitors, we completed the virtual archeology proposal based on realistic criteria, giving importance in 3D to textures and colors. It incorporated the anthropic and movable factors through matte painting techniques and images obtained with the support of re-enactment groups.Highlights: - The Fort of the Trinitat, built in the middle of the 16th century, is an extraordinary poliorcetic piece, conceived as an artillery machine, whose mission was to protect the natural port of Roses (Girona, Spain). - Between 2019 and 2021, an ambitious reconstruction of virtual archaeology has been carried out, developing a didactic iconography aimed at broad-spectrum visitors and formal education students. - The didactic iconography proposal developed in the Fort of the Trinitat does not try to compete with the large market productions, but it does try to explore sustainable intervention models to make the past and its heritage known.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47333705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, the research team analyzed the ruins of the church of Santa Maria de Monasterio Albo, located in the ancient village of Misterbianco (Sicily) and destroyed (together with the entire hamlet) by the 1669 eruption of Mount Etna. In the last years, some excavation campaigns brought the church to the light, unveiling the remains of the main portal and six altars, which are one of the most remarkable examples of Mannerist art in eastern Sicily. This research aimed to three-dimensional (3D) reconstruct both the altars and the portal, ideally reviving their original 17th century configuration. This goal was achieved through an in-depth archival research (documents dating back to the years between 1300 and 1666 were consulted), an analysis of Classic and Renaissance treatises, and two integrated digital survey campaigns (laser scans and photogrammetry). The outcome is represented by the 3D models of the seven artifacts, which include surviving parts reconstructed as photogrammetric meshes, several fragments were placed in their likely early location through a virtual anastylosis, and NURBS (Non Uniform Rational Basis-Splines) surfaces (recreating the no longer existing elements). The latter were 3D modelled based on the treatises (which provided information on the correct proportioning) or in analogy with other coeval similar artifacts. Overall, the digital reconstruction was based on the ethical principles of transparency of the intervention, recognition of non-original additions and distinction between evidence and hypothesis, according to the London Charter and the Seville Principles. The experimentation provides a valid support for possible interventions in the real world and is the starting point to develop a digital archive of the site, which would make the different accuracy levels the reconstruction explicit.Highlights:3D virtual reconstruction is effective to visualize and bring back to life ruined architectural artefacts.Information about the artefacts original appearance was harvested through digital survey campaigns, archival documents, and comparisons with iconographic sources and coeval buildings.The 3D reconstruction follows ethical principles of transparency and combines photogrammetric meshes (partly relocated through a virtual anastylosis) and NURBS surfaces.","PeriodicalId":44206,"journal":{"name":"Virtual Archaeology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2021-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42058459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
