Concrete methods

def catmulRom(points: Seq[Point], tension: Double): List[PathElement]

Interpolate a spline (a curve) that passes through all the given points, using the Catmul Rom formulation (see, e.g., https://en.wikipedia.org/wiki/Cubic_Hermite_spline)

Interpolate a spline (a curve) that passes through all the given points, using the Catmul Rom formulation (see, e.g., https://en.wikipedia.org/wiki/Cubic_Hermite_spline)

The tension can be changed to control how tightly the curve turns. It defaults to 0.5.

The Catmul Rom algorithm requires a point before and after each pair of points that define the curve. To meet this condition for the first and last points in points, they are repeated.

If points has less than two elements an empty List is returned.
