We present a new method for the construction of shape-preserving curves approximating a given set of 3D data, based on the space of "quintic like" polynomial splines with variable degrees recently introduced in [7]. These splines - which are C-3 and therefore curvature and torsion continuous - possess a very simple geometric structure, which permits to easily handle the shape-constraints.

Abstract
We present a new method for the construction of shape-preserving curves approximating a given set of 3D data, based on the space of "quintic like" polynomial splines with variable degrees recently introduced in [7]. These splines - which are C-3 and therefore curvature and torsion continuous - possess a very simple geometric structure, which permits to easily handle the shape-constraints.
