Approximate Parametrization of Space Algebraic Curves

Abstract

Given a non-rational real space curve and a tolerance ϵ>0\epsilon>0, we present an algorithm to approximately parametrize the curve. The algorithm checks whether a planar projection of the space curve is ϵ\epsilon-rational and, in the affirmative case, generates a planar parametrization that is lifted to an space parametrization. This output rational space curve is of the same degree as the input curve, both have the same structure at infinity, and the Hausdorff distance between them is always finite.
