We describe a method for constructing rational quadratic patch boundary curves for scattered data in R3. The method has quadric boundary precision; if the given point and normal data are extracted from a quadric, then the boundary curves will lie on this quadric. Each boundary curve is a conic section represented in the rational Bézier representation.
