During recent years, the synergy of virtual reality (VR) and photogrammetry has become an increasingly prevalent way to visualize, represent, preserve and disseminate cultural heritage objects. Photogrammetry offers a reliable method for a faithful and accurate image-based modeling of real-world objects, while VR applications provide not only visualization, but also an immersive and interactive experience of the photogrammetrically reconstructed cultural heritage. This research aims to create and apply the method for providing VR experience in the context of cultural heritage by developing a workflow for the VR applications based on photogrammetric models. The proposed workflow was applied on the iconostasis of the Serbian Orthodox Cathedral church of Saint Nicholas in Sremski Karlovci (Serbia). The presented method is based on the following main steps: generation ofan accurate 3D reconstruction of the iconostasisusing photogrammetry, the 3D model optimization, retopology, control and analysis and the process of creating the VR experience using a game-engine. The final result is an interactive walk through the church, which provides the user with an opportunity to visualize the iconostasis and its individual icons through different perspectives and multiple levels of detail, which is not otherwise possible when observing the church interior.

Cultural heritage and the attendant variety of built heritage demands a scientific approach from European committees: one related to the difficulties in its protection and management. This is primarily due to the lack of emergency protocols related to the structural knowledge and documentation pertaining to architecture and its ruins, specifically in terms of the goals of protection and intervention for endangered heritage affected by mechanical instabilities. Here, we focus on a rapid and reliable structural documentation pipeline for application to historical built heritage, and we introduce a case study of the Church of the Annunciation in Pokcha, Russia, while we also review the incorporation of integrated 3D survey products into reality-based models. This practice increases the possibility of systematising data through methodological phases and controlling the quality of numerical components into 3D polygonal meshes, with millimetric levels of detail and triangulation through the integration of terrestrial laser scanner and unmanned aerial vehicle survey data. These models are aimed at emphasising morphological qualities related to structural behaviour, thus highlighting areas of deformation and instability of the architectural system for analysis via computational platforms in view of obtaining information related to tensional behaviour and emergency risks.

AbstractThis paper maps out the possibilities of using virtual and augmented reality in the context of virtual museums and galleries. In addition to the many advantages that virtual reality offers in new knowledge acquisition and presentation of cultural heritage objects, we also describe some possible disadvantages or problems directly related to this technology. Next, we try to find the answer to whether the presentation of selected objects of cultural heritage through virtual reality brings better results compared to the presentation in a traditional, museal form in the research part of the article. In conclusion, we summarise and present the results of the conducted research based on the statements of 138 students who participated in our testing.

In this chapter, the issue of at-risk cultural heritage in the Middle East is addressed through the application of cyber-archaeology tools for data capture and dissemination. Working with an economic model to create a Heritage Asset District in the environs of Jerusalem, virtual reality for personal head-mounted devices and immersive CAVE platforms are used to help create high-value cultural heritage attractions designed to attract visitors to the district, thereby generating economic benefits. In the case study presented here, the district focuses on the Kidron Valley, which has its origin near the Temple Mount in the Old City of Jerusalem, and follows the river flowing eastward through the Judean Desert, where it empties into the Dead Sea. The most prominent cultural heritage site along the wadi (riverbed) is the Mar Saba Greek Orthodox monastery, dating to the fifth century CE. A helium-balloon photographic platform with high-definition photography and Structure from Motion (SfM) processing was used to create a 3D model of this impressive site that could be used for VR demonstrations. The demo is then made available over the MedArchNet (http://medarchnet.calit2.net/) online digital atlas to enable public engagement with Middle Eastern cultural heritage. This research is part of a University of California Office of the President Catalyst Grant concerning “At-Risk Cultural Heritage and the Digital Humanities.”

<p><strong>Abstract.</strong> This work describes the different attempts and the consequent results derived from the integration of an HBIM model into an already structured spatial database (DB) and its 3D visualisation in a GIS project.</p><p>This study is connected to the European ResCult (Increasing Resilience of Cultural Heritage) project where a DB for multiscale analyses was defined. To test the methodology proposed, the case study of Santa Maria dei Miracoli church in Venice was chosen since it represents a complex architectural heritage piece in a risk zone, it has been subject to a vast restoration intervention in the recent past but a digital documentation and model concerning it was missing.</p><p>The 3D model of the church was structured in Revit as a HBIM, with the association of different kind of information and data related to the architectural elements by means of ‘shared parameters’ and ‘system families’. This procedure allows to reach an even higher Level of Detail (LOD4), but lead to some issues related to the semantic and software interoperability. To solve these problems the existing DB for the resilience of cultural heritage was extended adding a new entity representing the architectural elements designed in the BIM project.</p><p>The aim of the test is to understand how the data and attributes inserted in the HBIM are converted and handled when dealing with a GIS DB, stepping from the IFC to the CityGML standard, through the FME software.</p>

Abstract. The paper deals with an interdisciplinary research activity aiming at developing a digital and integrated tool able to collect several data concerning the cultural heritage, and to manage and communicate them to a wide community. The small church of San Menna, located in the hamlet with same name in the municipality of Lucoli not so far from L’Aquila city, was the object of the research. The church has been chosen for its historical significance, its architectural peculiarity and for the valuable artworks that it preserves. Based on a photogrammetric model of the church, also used for the remote analysis of cultural asset (planimetric and evolutionary hypotheses, three-dimensional stratigraphic analysis, etc.) a virtual word usable in Virtual Reality (VR) has been developed. The VR setting allows the accessibility of a digital semantic model with information that can be activated with special interactive hotspots (images, texts and audio), which are able to provide an immersive and all-encompassing experience to the tourist. The potentialities of the same tool in the context of diagnosis and conservation process related to cultural heritage in seismic areas, such as those of the Abruzzi Apennines, have also been investigated through the integration of forms concerning the significant features of the artistic assets surveyed in the construction.
