Abstract: 
 This paper concerns the construction of a discontinuous
 parametric curve or surface from a finite set of points
 and tangent conditions. The method is adapted from the theory
 of the discrete smoothing variational splines to introduce a
 discontinuity set and some tangent conditions. Such method is
 justified by a convergence result.
