Rendering realistic sound from vibrating objects
Cornell researchers combined nonlinear shell dynamics, FastBEM acoustic precomputation, and far-field transfer maps to synthesize physically based sound.
Dynamic impact sounds
Rumbling containers, plastic bottles, cymbals, sheet metal, and breaking glass demonstrate object-dependent radiation.
Harmonic shells
FastBEM precomputes acoustic responses that can be reused efficiently during animation playback.
Research contribution
Physics and efficient sound synthesis
The method predicts nonlinear thin-shell motion and maps the resulting vibration to radiated sound. Precomputed acoustic transfer maps make detailed boundary-element radiation practical for interactive media workflows.
