Curvature - Wikipedia

https://en.wikipedia.org/wiki/Curvature

The mean curvature is an extrinsic measure of curvature equal to half the sum of the principal curvatures, k 1 + k 2 / 2. It has a dimension of length −1. Mean curvature is closely related to the first variation of surface area. …

To measure the curvature at a point you have to find the circle of best fit at that point. This is called the osculating (kissing) circle. The curvature of the curve at that point is defined to be the reciprocal of the radius of the …

What are simple methods for calculating curvature of a curve?

Going around you can probably get the curvature by looking at the 1st and 2nd gradients. In Matlab, it is giving something like: dx = gradient (x); ddx = gradient (dx); dy = gradient (y); ddy =...

Radius of Curvature -- from Wolfram MathWorld

https://mathworld.wolfram.com/RadiusofCurvature.html

The radius of curvature is given by R=1/(|kappa|), (1) where kappa is the curvature. At a given point on a curve, R is the radius of the osculating circle. The …
