A simple numerical method for calculating paths of creeping rays around an arbitrary convex object is presented. The adventage of this method is that the path of creeping ray is iteratively determined from initial values of incident point and incident direction of the creeping ray without solving differential equation of geodesic path. As the numerical examples, the path of creeping ray on the prolate spheroid and the resonance path of natural modes are shown.
