arc_length_to_parameter#
- Spline.arc_length_to_parameter(s, atol=0.0001)#

- Parameters:
- sfloat or np.array
Length on curve.
- atolfloat

Examples
>>> spline = splinebox.Spline(M=4, basis_function=splinebox.B3(), closed=False) >>> spline.control_points=np.array([[2], [3], [2], [6], [1], [2]])
>>> spline.arc_length_to_parameter(2.2) 2.12
>>> spline.arc_length(0, 2.12) 2.2
