Classical 3D modelling devices are often not suitable for works of art.
This is generally due to the high complexity of these artworks, and to the high precision needed in the field of their diagnostics, documenting, and classification.

Modern 3D graphics techniques, together with 3D scanning systems, allow to reproduce with high resolution the object shape.

Digital 3D models present a variety of applications, like virtual museums, 3D archives and object reproduction with "fast prototyping" techniques.
They are also used to support the study the artwork and to analyse the conservation interventions.
Among the 3D scanning contactless devices, the laser scanning system is most likely the one which optimally combines high resolution and versatility.

Among the 3D scanning contactless devices, the laser scanning system is most likely the one which optimally combines high resolution and versatility, making this instrument specially suitable for in situ measures, even in adverse lighting and environmental conditions.
