A practical method for computing with piecewise Chebyshevian splines
Carolina Vittoria Beccari, Giulio Casciola, Lucia Romani
A piecewise Chebyshevian spline space is good for design when it possesses a B-spline basis and this property is preserved under knot insertion. The interest in such kind of spaces…
Pythagorean-Hodograph B-Spline Curves
Gudrun Albrecht, Carolina Vittoria Beccari, Jean-Charles Canonne +1
We introduce the new class of planar Pythagorean-Hodograph (PH) B-Spline curves. They can be seen as a generalization of the well-known class of planar Pythagorean-Hodograph (PH) B…
Multigrid methods: grid transfer operators and subdivision schemes
Maria Charina, Marco Donatelli, Lucia Romani +1
The convergence rate of a multigrid method depends on the properties of the smoother and the so-called grid transfer operator. In this paper we define and analyze new grid transfer…
