  • Methods and systems for direct-to-indirect acoustic radiance transfer
    Patent number: 8995675
    Abstract: Methods, systems, and computer program products for simulating propagation of sound in a static scene can be operated for pre-computing a transfer operator for simulating results of sound reflection within a modeled scene, simulating distribution of sound energy from a sound source positioned within the scene, applying the transfer operator to the distribution of sound energy from the sound source to compute simulated sound at a plurality of points within the scene, and simulating collection of sound energy from the plurality of points within the scene to a listener positioned within the scene.
    Type: Grant
    Filed: December 5, 2011
    Date of Patent: March 31, 2015
    Assignee: The University of North Carolina at Chapel Hill
    Inventors: Anish Chandak, Lakulish Shailesh Antani, Micah Taylor, Dinesh Manocha
  • Methods, systems, and computer readable media for fast geometric sound propagation using visibility computations
    Patent number: 8847965
    Abstract: Methods, systems, and computer program products for simulating sound propagation can be operable to define a sound source position within a modeled scene having a given geometry and construct a visibility tree for modeling sound propagation paths within the scene. Using from-region visibility techniques to model sound diffraction and from-point visibility technique to model specular sound reflections within the scene, the size of the visibility tree can be reduced. Using the visibility tree, an impulse response can be generated for the scene, and the impulse response can be used to simulate sound propagation in the scene.
