No, I want to calculate the curvature of a surface, any surface, given a 
number of points on the surface surounding the evaluation point and 
their normals. Maybe the average vdot of the normal at each sample with 
the normal at the evaluation point. Or something based on the average 
distance from a point just "above" the evaluation point.
This is for a curvature pattern I have been working on, inspired by the 
patina thread in .advanced-users. :-)

I will make a more detailed post there soon. Or should it go to 
.unofficial.patches, since it relates to a patch and not directly to 
POV-Ray? Or to .general, because the problem itself doesn't have 
anything to do with either patches or POV-Ray, but math, and here is a 
group for "general" stuff, which would seem to include math? See why I 
thought of the .binaries.math group?
Well, I tend to over-analyze things, so I will just shut up and head 
over to .advanced-users. :-)
