    (The Eurographics Association, 2023) Mercuri, Fulvio; Pietroni, Eva; D'Annibale, Enzo; Paoloni, Stefano; Orazi, Noemi; Ferdani, Daniele; Zammit, Ugo; Ronchi, Diego; Bucciero, Alberto; Fanini, Bruno; Graf, Holger; Pescarin, Sofia; Rizvic, Selma
    This paper proposes a new method for the study of cultural heritage. A 3Dmodel in the mid-wavelength spectral range of infrared radiation is realized for the depth-resolved study of artworks. In particular, pulsed thermography is used to obtain a virtual 4D representation of some artifacts. The goal is to facilitate the end-user experience making it possible to explore subsurface elements in a digital 3D model. In the proposed approach, the three-dimensional geometry of the artifact is reconstructed by directly processing the infrared images using Structure from Motion techniques. Finally, the results of the humanities and natural sciences studies are mapped onto the 4D model in the form of interactive semantic annotations and visualized in a 3D web platform

    Hybrid XR Collaborative and Guided Experiences in Cultural Heritage: Brancacci POV Prototype
    (The Eurographics Association, 2023) Pescarin, Sofia; Cerato, Ivana; D'Annibale, Enzo; Fanini, Bruno; Ferdani, Daniele; Fà, Rachele Manganelli Del; Marasco, Alessandra; Massidda, Marcello; Palombini, Augusto; Ronchi, Diego; Bucciero, Alberto; Fanini, Bruno; Graf, Holger; Pescarin, Sofia; Rizvic, Selma
    In this work, we present a research prototype of a hybrid XR experience for cultural tourism, accessible by any potential device, including immersive VR headsets. It has been designed to better answer visitors' expectations and to overcome the limitations offered by traditional Virtual Tours (VT). We present the conceptual model, prototype, applied case study and users survey. The overall result has shown how the development of a collaborative and guided experience, enhanced by the use of a gamified narrative, has produced an increased perception of authenticity of the VT.
