have some 2D data in Julia representing a circular feature with some “holes” in it. I like to interpolate these holes by finding points fitting on a curve representing the shape of the feature. Using Julia’s PlotlyJS library I was able to find a nice spline interpolation curve for the points visual…

Copy and pasting here one of the examples and renaming your sample points as data: using Dierckx, Plots t = 1:size(data,1) spl = ParametricSpline(t, data', bc="extrapolate", s=0.0) tfine= range(1, size(data,1), 200) Pfine = evaluate(spl, tfine) t0, t1 = 12.5, 20.6 P0, P1 = evaluate.((spl,), [t0, t1…

Thank you for the hint. Unfortunately I don’t fully understand how to adopt it. Could you give an example?

I have improved it further, parameterizing using integers, so that it is easier to count the points anti-clockwise and know where to place the new ones.

You can use parametric splines. See some examples in this other thread.
