For 3D content, large-scale datasets, such as Objaverse or ShapeNet, and repositories, such as Sketchfab, have been compiled. Within the European 3DBigDataSpace project, a consortium of 10 partners assesses open licensed 3D models to select and retrieve those models particularly representing cultural heritage objects in Europe to aggregate them into the European Data Space. As key part of that work is the classification and geolocalization of 3D content, with mesh models viewable via different viewers and tested in different scenarios such as museum exhibitions, cultural tourism, or education. This article highlights the steps taken (1) to compile a large-scale pool of 3D assets of cultural heritage and ready-to-use viewer applications and (2) to enrich and (3) utilize them in various settings.
