Cup-marked stone, Göteborgs Stadsmuseum

Upper half of a cup-marked stone from the exhibition of Göteborgs Stadsmuseum ([https://goteborgsstadsmuseum.se/en](https://goteborgsstadsmuseum.se/en)). The model results from a quick test of the suitability of a smartphone for 3D photogrammetry under ambient (= poor) lighting conditions. While the upper half models quite well, the lower half of the boulder-like stone has been cut off due to modeling problems in the dark shadows. No cup mark has been harmed in the process. Made from 35 photos with Agisoft Metashape in April 2019. Imagery shot by Andreas Heege with a Samsung S8. Source: Objaverse 1.0 / Sketchfab
