Automatic illustration of lithics from 3D scanned models

The manual drawing of lithics artefacts is a very time-consuming process and may result cumbersome, especially if carried out within archaeological sites. In this context, a 3D digital model of the artefact could be very useful. Nowadays, several digitizing technologies are available to easily acquire information about the shape of an object. Virtual models can be used to create a digital museum or to share information between Scholars. On the other hand, the manual drawing of a lithic artefact contains information about the technologies used for its manufacturing as the core reduction, chipping technology, detaching sequence of supports. In this work, a methodology to easily obtain a hand-made-like drawing of lithic artefacts is proposed. The method is based on the 3D acquisition of the object with a structured-light based scanner and a sequence of digital processing steps of the acquired data.
