where the functions
that appear are called "B-spline functions" (B for "basic")
generalising the Bernstein polynomials of the Bézier curves.

SPLINE CURVE
| The name comes from the splines used in the industry
to fit certain shapes.
See this book page 66. |
The spline curves are the continuous piecewise polynomial
curves generalising the Bézier
curves, which are polynomial.
