Precomputed Wave Simulation for Real-Time Sound Propagation of Dynamic Sources in Complex Scenes
A method for real-time sound propagation that uses numerical simulation to capture all wave effects, including diffraction, for moving sources. This paper demonstrates realistic effects such as diffraction passing low behind obstructions, "hollow" resonance in empty rooms, sound diffusion in fully furnished rooms, and realistic late reverberation.
Rigid-Body Fracture Sound With Precomputed Soundbanks
A physically based algorithm for synthesizing sounds synchronized with brittle fracture animations. To reduce sound-model generation costs for complex fracture debris, this method introduces precomputed rigid-body soundbanks comprised of precomputed ellipsoidal sound proxies.
Sounding Liquids: Automatic Sound Synthesis From Fluid Simulation
This approach couples physically based equations for bubble resonance with real-time and hybrid grid-SPH-based fluid simulators to automatically synthesize multi-mode liquid sounds directly from visual simulations of fluid dynamics.
A Practical Simulation of Dispersed Bubble Flow
This paper introduces a new framework for simulating dispersed bubble flow. In this method, average motion of bubbles is approximated as a continuum, while the sub-grid interactions among bubbles are computed using a new stochastic solver. Using this method, complex scenes with millions of bubbles can be simulated efficiently.
