ABSTRACT
Shape represents highly significant data for the historical and artistic evaluation, the diagnostic analysis and the conservation of an artwork. The possible scenarios involved in the use of 3D digital models range from the monitoring of deterioration due to pollutants, to the realization of digital archives, from reverseengineering to fast-prototyping, and from the analysis of the conservation state to the monitoring of restoration interventions. Moreover, it is possible to monitor the form of variations by computing the differences between measurements at different times.
