Finsler and Cartan geometries are shown to provide seismological science’s Seismic Ray Theory, with a streamlined mathematical formalism which is then applied to signals in materials with azimuthal symmetry whose (qP)-wave solution of the eiconal equation, yields a regular Hamiltonian. The Legendre transformation theory plus use of software, MAPLE, provides a means to obtain ray velocities as functions of ray angle with exact formulas. The use of “polar constructions” as is traditional in this field can thus be circumvented, once tables are constructed using explicit elasticity constants.
