| Résumé : |
 |
On a four-directional uniform mesh of the plane, we define and study C0 Gori–Pitolli (abbreviated as GP) quadratics and C1 GP quartics generated by integer translates of GP box-splines generalizing respectively the classical C1 quadratic box-spline and one of the C2 quartic box-splines. More specifically, we study the approximation of a bivariate function f by some quasi-interpolants and interpolants with values in these generalized spline spaces |
