10:05 a.m.: 3D Building Memory Race Shells and missiles have rained down on Ukrainian cities since the start of the war, taking lives but also damaging historic buildings. Cultural services seek to preserve their memory with cutting-edge technology and 3D scans. Built in 1887, the Kharkiv fire station was severely damaged by Russian strikes. The red brick building with its surveillance tower is emblematic of Kharkiv’s industrial revolution at the end of the 19th century. With his laser scanner, Emmanuel Durand, a French engineer specializing in 3D data acquisition, “records” the building from every angle. “The scanner takes 500.00 points per second. On this station, we will have 10 million points. Then we will change stations and go all around the building, outside and inside. A billion points…”, he explains. In the evening, he gathers all the data on a computer, “like pieces of a puzzle”, to virtually reconstruct the building. The finished result is a perfect reproduction at 5 millimeters, which can then be turned around, or cut into slices. You can also see the craters of the explosions whose blast shook the structure. In Kharkiv alone, some 500 buildings are listed as being of historical interest, most of them in the city center under Russian fire.
