In the last few years 3D technologies have found in the archaeological studies an important application field and, from niche experimentations, have become a standard tool for the documentation, investigation and presentation of sites, artefacts and excavations.

The aim of this half-day workshop is to present to the archaeological community the various tools offered by MeshLab for the manipulation and use of 3D data in the archaeology field.

MeshLab is an Open Source tool for the visualization and processing of large, unstructured 3D models, developed by the Visual Computing Lab (ISTI-CNR). Born as a university project, MeshLab has steadily grown in features and usability, reaching more than 100.000 downloads in the last year. MeshLab is used by hundreds of research groups and industries, and by thousands of 3D hobbyists. Featuring various state-of-the art 3D processing algorithms (often implemented by their academic authors), it represents a solid and free alternative to commercial tools for 3D scanning data management.

The workshop will cover the various stages of the use of a 3D model, from its creation to its complete exploitation, focusing on the functionalities more interesting from a CH and Archaeological point of view

3D Model creation from raw data: the tools needed to process raw 3D data coming from 3D scanners (triangulation, structured light or time of flight) and 3d-from-images reconstruction tools (like Arc3D, PhotoFly or PhotoScan). Scan alignment and merging. Photographic alignment, color mapping and texture generation.

3D model manipulation: model cleaning and filtering. Smoothing, simplification and format conversion.
Measurement and data extraction: taking measures on a 3D geometry, point picking, model annotation, numerical comparison between 3D geometries.

Visualization and documentation: advanced shading, rendering, image generation.
