Fig. 4 – The coarse alignment of the bas-relief (top) and the final model (middle); almost all of the alignments required just 1 iteration.

Fig. 5 – Virtual Inspector: the “Arrigo VII” statue rendered with active hot spots (top); a short popup panel with a short info, describing the missing hand, appears when the mouse passes over the hotspot located on the hand (left), or a more complex page associated to the hotspot on the neck (right).

Fig. 6 – A 3D model reconstructed from just a sequence of approximatively one hundred high resolution photos. The reconstruction was performed using the tools developed within the EU IST NoE “Epoch”.
