Shape relief constitutes a precious contribution to the analysis and monitoring of the state of conservation of objects of historical or artistic interest.

Optical techniques for measuring the shape, associated with the most recent digital techniques of data analysis, enables the acquisition and computer-aided processing of 3D models, the application of which ranges from digital restoration to the realization of virtual reality complex sceneries, form digital storage, therefore unalterable, to the production of faithful copies of artwork.

Furthermore a 3D model is an ideal support for the integration of data coming from other diagnostics investigation.

GBC has developed a series of instruments for 3D relief of objects which range from architectural structures to small archaeological finds.
3D data processing is carried out in partnership with the Visual Computing Group of IST-CNR of Pisa.
