Generalized full wavefield modeling is a modeling process that utilizes reflection and transmission operators for inhomogeneous media in order to produce the wavefields. We extend this modeling process to the quasi-elastic anisotropic situation, where the elastodynamic generalized vertical wavenumber operator for P-waves is embedded in the acoustic formulation, assuming TIV media. Two examples are computed; one for homogeneous and the other for inhomogeneous media. The wavefields generated exhibit the typical angular distortion behavior introduced by anisotropy. While useful on its own, this extension of generalized full wavefield modeling paves the road to the inversion process, model-independent joint migration inversion.
