Abstract
Methods, systems, and computer readable media for simulating sound propagation are disclosed. According to one method, the method includes decomposing a virtual environment scene including at least one object into a plurality of surface regions, wherein each of the surface regions includes a plurality of surface patches. The method further includes organizing sound rays generated by a sound source in the virtual environment scene into a plurality of path tracing groups, wherein each of the path tracing groups comprises a group of the rays that traverses a sequence of surface patches. The method also includes determining, for each of the path tracing groups, a sound intensity by combining a sound intensity computed for a current time with one or more previously computed sound intensities respectively associated with previous times and generating a simulated output sound at a listener position using the determined sound intensities.
