ABSTRACT
This is a rather highly nonlinear system of equations in the vk, as the segments £& and 77fc, at least in the C2 case, depend on all of the vk-But even when, for a given spline method, the vk can be determined by the optimality conditions (8.8), it remains an open question whether and why the corresponding parametric curve is always visually preferable to that corresponding to the use of (8.4).
