Abstract

Given a parametric representation of an algebraic projective surface $S$ of the ordinary space we give a new algorithm for finding the implicit cartesian equation of $S$. The algorithm is based on finding a suitable finite number of points on $S$ and computing, by linear algebra, the equation of the surface of least degree that passes through the points.
