The Geometry behind the “Fontana di Sala Grande” a Case Study of Reverse Modeling

The work presented here will show the story, the procedures and the methodology operated by our team during the 2010 to rebuild the fountain to the original composition, digitally working of the remains and reconstructing the missing parts, to reach the final result represented by the current, permanent, exhibition of the complete group in the Bargello Museum. Reverse modeling is a special technique implemented in pipelines from the field of design and mechanic engineering and it is aimed at converting meshes from 3D laser scanner in NURBS models. These techniques played an essential role for the reassembling process described in this paper: the missing arch that once connected the statues belonging to the fountain was re-designed inside an interdisciplinary framework where different skills allowed the solving of a difficult and delicate restitution. 4th International Conference, EuroMed 2012, Lemessos, Cyprus, October 29 -- November 3, 2012, Proceedings Series: Lecture Notes in Computer Science, Vol. 7616 Subseries: Information Systems and Applications, incl.
