Abstract

The numerical solution of ray tracing problems in complex 3D media is considered in this paper that reviews some of the work and applications in which the author and his collaborators have been engaged in the past few years. The paper is not a survey but rather tries to point out what are the main issues common to many applications and how we have attacked the problem and implemented computational tools with general applicability to such disparate fields as earthquake seismology, oil prospecting, and non- destructive evaluation of complex mechanical parts. 1 Introduction Ray tracing provides a way to simulate numerically some aspects of wave propagation. It is not as comprehensive as finite difference or finite element methods, but it is considerably more economical. With its geometrical flavour it is also a more intuitive tool, producing results t
