Project pipeline

  1. Photogrammetric acquisition in the bell tower under difficult light, access, and reflection conditions.
  2. Triangle-mesh reconstruction, neural completion support, cleanup, and web-level model reduction.
  3. Finite-element modal analysis and physically informed sound design prepared for a later public audio release.
  4. Web publication, research documentation, and long-term data preparation with provenance-aware metadata.

Public preview status

This deployment opens the project context and the 3D bell explorer first. Sound synthesis, bell triggering, and the city auralization map remain disabled until the next review step.
