Some Spline Terminology

We are going to briefly discuss some of the terminology related to the spline portion of the interactive web app Exploring Bezier and Spline Curves, together with the associated help page and its links.

We recognize that, as the technology has evolved, the usage of these terms has sometimes drifted from the definitions put forth in the fundamental work of I. J. Schoenberg, C. R. de Boor, and others.

We will describe our use of the terms and also will point out some alternative usages below. We will not try to be totally mathematically rigorous or complete.
