    title = {{Local Parametrization of Cubic Surfaces}},
    language = {english},
    abstract = {Algebraic surfaces -- which are frequently used in geometric modelling -- are represented either in implicit or parametric form. Several techniques for parameterizing a rational algebraic surface as a whole exist. However, in many applications, it suffices to parameterize a small portion of the surface. This motivates the analysis of local parametrizations, i.e., parametrizations of a small neighborhood of a given point $P$ of the surface $S$. In this paper we introduce several techniques for generating such parameterizations for nonsingular cubic surfaces. For this class of surfaces, it is shown that the local parametrization problem can be solved for all points, and any such surface can be covered completely.},
