Abstract

The subject matter described herein includes a method for simulating directional sound reverberation. The method includes performing ray tracing from a listener position in a scene to surface as visible from a listener position. The method further includes determining a directional local visibility representing a distance from a listener position to nearer surface in the scene alone each ray. The method further includes determining directional reverberation at the listener position based on the directional local visibility. The method further includes rendering a simulated sound indicative of the directional reverberation at the listener position.
