In this work we propose SPLISURF, a tool developed in Matlab, referring to the generation of local bivariate quadratic C1 quasi-interpolating (q-i) splines, defined as a linear combination of B−splines on uniform and non uniform criss-cross (or type 2) triangulations. Moreover we briefly review some of their properties and present numerical results.

Abstract
In this work we propose SPLISURF, a tool developed in Matlab, referring to the generation of local bivariate quadratic C1 quasi-interpolating (q-i) splines, defined as a linear combination of B−splines on uniform and non uniform criss-cross (or type 2) triangulations. Moreover we briefly review some of their properties and present numerical results.
