Abstract : |
A primary challenge in acoustic modeling is computation of reverberation paths from sound sources fast enough for real-time auralization. This paper describes a beam tracing method based on precomputed spatial subdivision and ?beam tree ? data structures that enables real-time acoustic modeling and auralization for sound sources at fixed locations in interactive virtual environment applications. The proposed beam tracing method: 1) supports evaluation of reverberation paths at interactive rates, 2) scales to compute high-order reflections and large environments, and 3) extends naturally to compute paths of diffraction and diffuse reflection efficiently. 1, |
