Singularities often cause trouble in tracing rays in inhomogeneous anisotropic media. The ray-tracing algorithms can break down in the vicinity of the singularities because the medium becomes nearly degenerate and the ...

Possible applications of dynamic ray tracing to the 3-D Born and Kirchhoff inversion of seismic-reflection data are discussed. It is shown that the most important quantities in the inversion integrals, such as the Beylkin ...

Photorealistic rendering algorithms are used in various applications, like movies, games, and CAD software. A class of algorithms that is extremely important for this end is the Ray-tracing algorithms, which uses geometric ...
