Abstract
There is provided a sound tracing method. The method includes: a setup processing step of setting ray information; a ray generation step of generating a sound ray; a traversal/intersection test step of generating hit triangle information; a propagation path validation (PPV) step of searching a sound path; a guide plane sort step of generating and sorting a guide plane; a Reverb Geometry Collect/Reverb Plane Sort (RGC/RPS) step of generating and sorting a reverb plane; and an impulse response calculation step of calculating an impulse response (IR) and storing the calculated IR in a valid path buffer.
