Claim 8:
9. A sound tracing method comprising:
(a) generating a first acceleration structure for a static scene in a sound space;
(b) executing an intersection test for detecting whether each of a plurality of dynamic objects constituting a dynamic scene in the sound space affects a sound propagation path;
(c) selecting, based on a result of the intersection test, only the dynamic objects that affect the sound propagation path and then generating, based on the selected dynamic objects, a second acceleration structure including only the selected dynamic objects, among the plurality of dynamic objects, that affect the sound propagation path for the dynamic scene; and
(d) generating a 3D sound by performing sound tracing based on the first and second acceleration structures.
