 Fabrice, Thomas, Thomas, Herbie, Gabriel, and others who might be following this,

I just posted Version 6 of my curvature plugin at http://www.optinav.info/Curvature.htm I hope it is finished.
My ulterior motive in writing this was that the curvature subject reminded me of the Kelvin effect in evaporating respiratory droplets that are trying to propagate COVID-19.  I realize that this is probably not the OP application.  Also, [1] suggests the Kelvin effect becomes important for droplets smaller than 0.5 microns, and this is pretty small for this case. Even (dried) talking droplets are 0.9 microns or so. Anyway, it is what it is. An introduction to this subject can be found under "Interesting Video" on the top of http://www.optinav.info/ I'd like feedback from biologists.
