<p>The article presents a method to approximate surfaces of revolution with nonrational B-splines. The profile curve is assumed to be a nonrational curve, and the revolution is performed by a nonrational approximation of the circular arc. The approximation requires only a modest number of control points in the range of engineering tolerances and provides a quasiuniform parametrization as compared to the quadratic rational circle.</p>
