In interviews Tallon said that looking at the details of construction was like looking into the mind of the builders. The best way to take in those details as a whole was to build the cathedral digitally. He used state of the art 3D scanners to collect billions of datapoints. Tallon built a digital twin of the Cathedral. LUX has an excellent post about this (here). And a podcast for those...
