ChiselEcho: A 3‑D archive isn’t just a pretty trick—it’s a safety net. You get an exact record of every flake, scar, and inscription before it’s worn away. If a monument later falls apart, you can reconstruct the geometry and surface details digitally, which helps restorers decide where to put new stone or how to treat the existing surface. It also lets scholars run simulations of weathering, track changes over time, and share the data with people who can’t visit the site. The downside is the cost of scanning, storage, and maintenance, but the long‑term payoff of preserving the stone’s essence is worth the effort.
