Classification: CPC H | IPC H

Claim 0:
1. A sound tracing apparatus comprising:
a first acceleration structure generation unit configured to generate a first acceleration structure for a static scene in a sound space;
an intersection test execution unit configured to perform an intersection test on each of a plurality of dynamic objects constituting a dynamic scene in the sound space to detect whether or not the dynamic object affects a sound propagation path;
a second acceleration structure generation unit configured to select, based on a result of the intersection test, only the dynamic objects that affect the sound propagation path, and then generate, 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
a sound generation unit configured to generate a 3D sound by performing sound tracing based on the first and second acceleration structures,
wherein the first acceleration structure generation unit, the intersection test execution unit, the second acceleration structure generation unit, and the sound generation unit are each implemented via at least one processor.
