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.
Claims21
A method for simulating sound propagation within a scene, the method comprising:
- 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.
A computer readable medium having stored thereon executable instructions that when executed by the processor of a computer control the computer to perform steps comprising:
- 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.
A system for simulating sound propagation within a scene, the system comprising:
- a transfer operator embodied in a computer readable medium for simulating results of sound reflection within a scene;
- and
- a sound simulator for receiving as input a distribution of sound energy from a sound source positioned within a scene and for 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.
