ART3MIS: RAY-BASED TEXTUAL ANNOTATION ON 3D CULTURAL OBJECTS

Beyond the simplistic three-dimensional (3D) visualisation, archaeologists, as well as cultural heritage experts and practitioners, need applications with advanced functionalities, such as the annotation and the attachment of metadata on particular regions of the 3D digital objects. Various approaches have been presented to tackle this challenge, most of them achieving excellent results in the domain of their application, confined, though, in that specific domain and particular problem. In this paper, we present ART3mis, a general-purpose, user-friendly, interactive textual annotation tool for 3D objects, which is primarily attuned to aid cultural heritage conservators, restorers, and curators with no technical skills in 3D imaging and graphics, in easily handling, segmenting, and annotating 3D digital replicas of artefacts. ART3mis ap-plies a user-driven, direct-on-surface approach and is able to handle detailed 3D cultural objects in real-time and store textual annotations for multiple complex regions in JSON data forma
