In this paper we generate and study new cubature formulas based on spline quasi-interpolants defined as linear combinations of C1 bivariate quadratic B-splines on a rectangular domain Ω, endowed with a non-uniform criss-cross triangulation, with dis

International audience; In this paper we consider spaces of unequally smooth local bivariate quadratic splines, defined on criss-cross triangulations of a rectangular domain. For such spaces we present some results on the dimension and on a local bas
