Earlier this week, the world was sent into shock when it was reported that the historic Notre Dame Cathedral had caught on fire. Given the historic significance of the building and the priceless artifacts, artworks, and knowledge stored in the building, many were understandably worried that we could lose it all.
Thankfully the fire has since been extinguished, and for the most part, the cathedral survived, but now comes the part about repairing and rebuilding parts of the structure that was damaged. So, how are they going to go about doing that? Thankfully, it appears that a potential solution has been found which involves the use of 3D scans of the Notre Dame Cathedral taken by the late Vassar art historian Andrew Tallon.
The 3D scans of the building were undertaken several years ago with the use of a laser mounted on a tripod, where Tallon managed to record information about the building that might have otherwise been overlooked. Thanks to Tallon’s efforts, a whopping 1 billion points of data were recorded.
The laser would sweep the area in every direction, and whenever it hit a surface, the beam would bounce back and record the exact placement and surface. According to Tallon who spoke to Nat Geo back in 2015, if the scans were done properly, they should be accurate within 5 millimeters.
French President Emmanuel Macron has since pledged to rebuild Notre Dame in the next five years, and we have also seen how various huge tech companies, such as Apple, offer to donate money to help towards the reconstruction.
