A highly accurate 3D model is to support restoration work on the world's fourth largest church, Duomo di Milano, or Milan Cathedral in Italy. Millions of laser-scanned measurements have been combined with other survey data and photogrammetric images, allowing researchers from the Politecnico di Milano to generate both 2D and 3D visualisations, classical plans and elevations, as well as computer-generated animations. The main aim of the project was to obtain an understanding of the state of the spire in order to support restoration operations ahead of an International Expo due to take place in 2015.
