A blown-up Russian tank near Kyiv, a monument for Ukrainian writer Borys Hrinchenko, an apartment building destroyed by artillery and a slide in a children's playground covered in graffiti.
In Ukraine, these objects are among hundreds of landmarks, cultural sites, monuments and everyday things that civilians have scanned on mobile phones through an app called Polycam. The app's software generates a detailed 3D model that will live permanently in a digital archive as part of an initiative called Backup Ukraine.
The project, launched in April shortly after Russia invaded Ukraine, aims to digitally preserve the country's cultural heritage -- far from the reach of Russian attacks. The scans are so high-quality, the project's creators say, that they can be projected in a physical space to explore for educational purposes and can also be used to reconstruct destroyed cultural artifacts.
