Constructing Explicit B-Spline

Numerical Analysis 2014-09-15 v1

Abstract

We introduce here a direct method to construct multivariate explicit B-spline bases. B-splines are piecewise polynomials, which are defined on adjacent tetrahedra and which are CrC^{r} continuous throughout. The CrC^{r} continuity is enforced by making sure that all directional derivatives of order rr, and lower, on the boundaries of adjacent tetrahedra give the same values for both tetrahedra. The method presented here is explicit, in that we will provide an algorithm with which one can analytically construct the B-spline base that enforces CrC^{r} continuity for a given geometry.
