Mesure (and compare) the degree of curvature of a full curve

[ROGO (Young_Grasshopper)]

I want to define the overall extremity of curvature/jaggedness of closed 3D curves Let’s say between 1 and 10. 1 is a curve like Crv1 with relatively low jaggedness

And 10 is a curve like Crv2 with extreme curvature

I’ve seen some applications to measure curvature on a point but I’m not sure if there is a better way to aggregate the overall degree of curvature of a curve

Hi Quan Li,

Thank you for your response. Apologies, on reflection my question wasn’t clear enough. I want to measure the overall extremity of curvature/jaggedness of curves. Grading the curvature/jaggedness or “noise” as defined in your definition on a scale of 1 - 10.

So rather than creating noise, I want to measure the existing curvature/jaggedness across the whole curve. Thank you.

Here are some example curves.

Just an idea.

Fantastic Quan Li, I will take a look at this now. I was having issues getting curvature readings as converting to nurbs was something I was missing. Thank you.
