Trivariate quartic splines on type-6 tetrahedral partitions and their applications

Catterina Dagnino, Paola Lamberti, Sara Remogna

Abstract


In this paper we develop a 3D quasi-interpolating spline scheme, on a bounded domain, based on trivariate quartic C 2 box splines on type-6 tetrahedral partitions. Then, we describe some applications related both to the reconstruction of gridded volume data and to numerical integration. We also provide some numerical tests.
