Hello all!

We were measuring some of the morphometrics of a stingray barb, something that we wanted to find was the sharpness of the tip of the barb, is there any module or plug in to help with this? Considering writing a python plug in instead if it didn’t exist yet.

Attached is the barb we are working with\*

Thanks!
