3D meshes of wood samples derived from CT scan

The repository contains 3D meshes of 83 wood samples derived from X-ray computed tomography (CT) data. The samples are a part of the  LEIZA reference collection, which were created within the framework of the project "Mass Finds in Archaeological Collections", which was funded by the "Kulturstiftung des Bundes" and the "Kulturstiftung der Länder" from 15.04.2008 to 31.12.2011 as part of the "Program for the Conservation and Restoration of Mobile Cultural Property" (KUR, see www.rgzm.de/kur).

Around 10 years later, the wood samples were digitized using an in-house laboratory X-ray CT system (Diondo  d2, Germany) at HSLU with a nominal voxel size between 27 and 44 μm in order to analyse the structure of the interior. 3D models were derived from the CT data and these were cleaned in post-processing, holes closed and the resolution reduced to 0.2 mm. You can download these 3D models here. For each wood sample the following files are available: a file of the 3D mesh in *.stl format and two files with metadata in *.json and *.ttl format. The 3D data acquisition was carried out during November 2019 - April 2021.

The CuTAWAY project was funded by the German Research Foundation (DFG) and the Swiss National Science Foundation (SNSF) from 2019 to 2023 (CuTAWAY - Conservation and Wood Analyses, DFG - 416877131 and SNSF - 200021E_183684).
