Frequency-dependent ray tracing through an interface

摘要

Computing systems and methods for improving processing of collected data are disclosed. In one embodiment, while ray-tracing through a sub-surface region, a frequency- dependent outgoing ray direction is computed from a point on an interface disposed in the sub-surface region when the ray tracing is at the interface.

1. A method for ray tracing through a sub-surface region that includes an interface, comprising:
when the ray tracing is before the interface, performing conventional ray tracing through the sub-surface region; and when the ray tracing is at the interface, computing, using a computer, a frequency-dependent outgoing ray direction from a point on the interface, wherein the computation is based at least in part on:
an incoming ray direction,one or more surface normals, anda computed boundary integral that is based at least in part on the incoming ray direction and a frequency parameter.
