Document Type and Number:
WIPO Patent Application WO/2020/138716
Kind Code:
A1
Abstract:
The present invention relates to a sound tracing apparatus and method, the sound tracing apparatus comprising: a first acceleration structure generation unit for generating a first acceleration structure of a static scene of a sound space; an intersection testing unit for detecting whether a sound propagation path is affected by performing an intersection test on each of a plurality of dynamic objects constituting a dynamic scene of the sound space; a second acceleration structure generation unit for generating a second acceleration structure of the dynamic scene after selecting, as a result of the intersection test, a dynamic object that affects the sound propagation path; and a sound generation unit for generating a three-dimensional sound by performing sound tracing on the basis of the first and second acceleration structures.
