Abstract: In this work, a toric surface is explicitly approximated by a biconic model by decomposing the toric surface into a biconic–identical component and other elliptical cylinder–related residual components. These residual components determine the zone– and the azimuthal orientation–dependent approximation accuracy. In addition to the analytical underpinning, a direct fit of the biconic model to a data set sampled from a toric surface is performed and consistent results are obtained.
