Two-Dimensional Splines, Surface Splines, Bézier Splines, B-Splines

1996
Assume that we are given a rectangular grid G in the x,y-plane $$ G = \left\{ {\left. {(x_{i,} y_j )\,\,\,\,\,\,\,\,\,\,\,\,\left| \begin{gathered} a = x_0 < x_1 < \ldots < x_n = b \hfill \\ c = y_0 < y_1 < \ldots < y_m = d \hfill \\ \end{gathered} \right.} \right\}} \right. $$ with heights u ij defined at each point \( (x_i ,y_j ) \in G \) $$

Discrete splines and spline filters

IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing, 1992
An equation is derived for the Z transform of discrete polynomial splines for the general case of nonuniform knots. Two filter structures are provided for the computation and analysis of discrete splines, one for the one-sided factorial function representation and one for the B-spline representation.

Martensen Splines

BIT Numerical Mathematics, 2006
This paper is concerned with the construction of fundamental functions from the class of Martensen splines. These are Hermite-type polynomial splines in one dimension. The construction provides recursive formulae. Error estimates are presented too.

Splines and Spline Fitting Revisited

1996
This paper presents a detailed summary of the properties and basic facts about spline spaces and their B-spline bases. Examination is made of the many different joint-continuity conditions. Geometric continuity constraints are of special interest, as they appear to satisfy visual needs of the human observers.

Spline Curves and Spline Surfaces

1994
In the previous chapter, we used cubic parabolas (Equation 22) to interpolate the line of intersection P1P2 of the graph Γ with a vertical plane ψ. Analogously, a patch Ψ on Γ, which is roughly approximated by two triangles, can be replaced by a cubic graph that consists of all the cubic parabolas we get when we vary the plane ψ. Such a graph is called
