    3D for Studying Reuse in 19th Century Cairo: the Case of Saint-Maurice Residence
    (The Eurographics Association, 2021) Baillet, Vincent; Mora, Pascal; Cou, Corentin; Tournon-Valiente, Sarah; Volait, Mercedes; Granier, Xavier; Pacanowski, Romain; Guennebaud, Gaël; Hulusic, Vedad and Chalmers, Alan
    3D restitution is now a well-known tool to validate hypotheses on historical buildings that do not exist anymore. The present project takes the method a step further in order to explore the art historical topic of ornament reuse in 19th century revival architecture, particularly in Cairo. The case study is the Saint-Maurice residence, built 1875-79, for which an extensive collection of documents in varied formats, and from multiple locations and disciplines, has been conducted. The paper presents some preliminary results on the 3D restitution, the remaining open questions and the challenges they raise.

    Challenges in the Digitisation of a High-reflective Artwork
    (The Eurographics Association, 2021) Catalano, Chiara Eva; Brunetto, Erika; Mortara, Michela; Pizzi, Corrado; Hulusic, Vedad and Chalmers, Alan
    In this paper we report about the photogrammetric acquisition and reconstruction of a contemporary artwork, performed by offthe- shelf software. The ceramic piece of art is "Il Libro d'Oro del Terzo Paradiso" ("The Golden Book of the Third Paradise") by Michelangelo Pistoletto, accessed and studied in the framework of a regional project. This artefact is particularly challenging. On the one hand, it is golden coated and, as such, highly reflective. Hence, images are likely to suffer from highlight spots, shadows or self-reflections, and the reconstructed point cloud is typically noisy. On the other hand, the object exhibits simple geometry, mainly composed of planar surfaces, and is highly symmetric; however, it possesses detail features and undercuts. The symmetric nature of the object and reflections misled the image alignment, and the noise in the data turned out to be of the same scale as the detail features. We will discuss all the steps of the process, aimed at obtaining a high quality and accurate 3D model using low-cost tools.

    Interactive 3D Artefact Puzzles to Support Engagement Beyond the Museum Environment
    (The Eurographics Association, 2021) Rodriguez Echavarria, Karina; Samaroudi, Myrsini; LLoyd, Jack; Weyrich, Tim; Hulusic, Vedad and Chalmers, Alan
    The need for online 3D interactive experiences was evidenced during the COVID-19 lockdowns, as audiences across the world have been unable to visit museums, physically interact with their collections on site or digitally interact with technologies and digital media situated within such settings. As a response, this research addresses gaps identified in a review of the digital offerings from UK and US museums during the 2020 lockdowns, highlighting the limited number and nature of 3D interactive offerings provided, despite the wide efforts on 3D digitisation over the last decade. Thus, the research investigates the development and testing of an online 3D interactive activity, resembling a physical activity situated in the archaeological gallery of Brighton Museum and Art Gallery (UK). Through a pilot user survey, the research aims to understand what is the impact of such online offerings to better contextualise heritage collections; enhance cultural heritage learning and appreciation; and complement physical activities of similar nature. The analysis of audiences’' opinions about these interactions can be of great importance, as such activities have the power to enable active access to cultural heritage resources regardless of the physical location of users and transform heritage experiences in the long term. Our research indicates that, while the physical experience might offer advantages as far as it concerns the familiarity with the tactile nature of interaction, the digital counterpart has potential to allow for the experience of assembling the puzzle to achieve a wider reach.

    Reimagining a 2D Painted Portrait as a Kinetic 3D Sculpture
    (The Eurographics Association, 2021) Ellis, Ellen Conlan; Adzhiev, Valery; Hulusic, Vedad and Chalmers, Alan
    This paper describes a Cultural Heritage related project concerned with developing computer technology for reimagining a 2D painted still portrait made in a distinctive fine art style as an animated 3D sculpture whilst preserving the principal features of the initial painting yet resulting in an artefact of original quality. This work explores both artistic and technological aspects of a production pipeline. The case-study to prove the concept relies on Francis Bacon's ''Study for Portrait (Michel Leiris)''. A supplementary video shows the resulting animated piece with Bacon's voice-over.
