3D Ray tracing Through No-Flat Homogeneous Anisotropic Layers

Two-point ray tracing problem is solved for qP events in a piecewise homogeneous and laterally varying 3D anisotropic media by continuation techniques. The algorithm has the same performance and robustness as previous implementations of the continuation method for tracing rays in isotropic models. This procedure can be used as a forward problem routine in traveltime inversion for elastic parameters. Although the method do not allow general inhomogeneous anisotropic model it can be useful enough at the estimation process of a background model convenient for imaging purposes in anisotropic formations.
