Seismic Ray Tracing
https://parasollab.web.illinois.edu/research/stapl/seismic/
We will be working on developing an efficient parallel algorithm for Seismic Ray Tracing. The second phase of the project deals with implementing the algorithm in a parallel machine using the Standard Template Adaptive Parallel Library (STAPL) which is being developed at Texas A&M.
A fast algorithm for two-point seismic ray tracing
https://pubs.geoscienceworld.org/ssa/bssa/article/77/3/972/118980/A-fast-algorithm-for-two-point-seismic-ray-tracing
A new approximate algorithm for two-point ray tracing is proposed and tested in a variety of laterally heterogeneous velocity models. An initial path estimate is perturbed using a geometric interpretation of the ray equations, and the travel time along …

The computational efficiency of the basic minimum travel time tree (MTTT) algorithm for seismic ray tracing is improved by means of dynamically adjusting the pre-defined propagation area of secondary waves according to the spread of seismic waves.
Seismic ray tracing in anisotropic media: A modified …
https://library.seg.org/doi/10.1190/geo2013-0110.1
With this modified algorithm, two ray-tracing schemes are presented. The first scheme involves newly derived raypath equations, which are approximate for anisotropic media but the minimum-time constraint will ensure that the solution steadily converges to the true solution. The second scheme is based on the minimal variation principle.

Ray trace modelling can also optimise the acquisition parameters of 3D surveys (e.g. shooting direction, Ray et al. 2004 ). The input of the ray-tracing algorithm is a stack section. As seismic interpretation is usually carried out on migrated data, it means that the marker horizons have to be transferred to stack sections.

A Basical Study on Two-point Seismic Ray Tracing
http://www.ees.nmt.edu/outside/courses/GEOP523/Docs/yang.pdf
In seismology, ray tracing is based on the concept that seismic energy of infinitely high frequency follows a trajectory determined by the ray tracing equations. Physically, these equations describe how energy continues in the same direction until it …
Ray tracing (physics) - Wikipedia
https://en.wikipedia.org/wiki/Ray_tracing_(physics)
Ray tracing may be used to compute paths through a geophysical model, following them back to their source, such as an earthquake, or deducing the properties of the intervening material. In particular, the discovery of the seismic shadow zone (illustrated at right) allowed scientists to deduce the presence of Earth's molten core. General relativity
