Ochsendorf, who worked with Tallon on the project, says “such a 3D model can provide crucial information about the geometry and materials.” Tallon’s laser scan process used a Leica ScanStation C10 laser beam mounted on a tripod to engulf an area with a scan, measuring distances for every surface the laser hit. That continuous mapping created a 3D image of the cathedral that Tallon once said was accurate to within five millimeters. Ochsendorf says Tallon was able to make those scans work visually by pairing them with a panoramic photograph from the same spot, creating a near-realistic image of the space READ HERE
