From the beginning, it was clear that even the floor–to–ceiling, wall–to–wall brass canvas couldn’t contain the full story. While we worked on the production of the brass mural, we conceived of an augmented reality experience that would enrich the physical one. Again, the material presented unique challenges. Ordinary image recognition technology wouldn’t work on the back–lit, curved and reflective surface. In collaboration with our partners at Monogrid—a Florence–based digital interactive studio—we determined the positions from which visitors were most likely to aim the app. From these views, we segmented the wall into frames, within which we identified the most compelling visual components to act as markers. Calibrating the size and dimensions of them, we divided the wall into portions to create a seamless 3D tracking of the surface.
