Abstract
There is provided a method and apparatus for edge detection for diffraction of sound tracing, and the method includes a triangle detection step for detecting hit triangles hit with a ray departing from a sound source; and an edge detection step for calculating at least an edge point based on the hit triangles and determining whether diffraction occurs on the edge point by performing an intersection test for a test ray departing toward the at least edge point based on the sound source or a listener.
