Kuznetsov, E.B.; Yakimovich, A.Yu.
The best parameterization for parametric interpolation. (English)
[J] J. Comput. Appl. Math. 191, No. 2, 239-245 (2006). ISSN 0377-0427

The authors consider the problem of interpolation of curves and surfaces using parametric functions. The optimal parametrization conditions are obtained using the parametric continuation method. It is shown that the optimal parameter is the length of the curve to be interpolated (Theorem 1). For the parametric approximation of a surface, the optimal parametrization at each surface point is given by two orthogonal curves lying on the surface and passing trough this point. The optimal parameters are the lengths of the arcs of those curves.
