Trivariate quartic splines on type-6 tetrahedral partitions and their applications. (English) Zbl 1329.65046
Summary: 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.
