ProfCurvMax/ProfCurvMin identical to MaxCurve/MinCurve #26

Closed ailich closed 2 years ago

ailich commented 2 years ago

The formulas for these two are the same in Wood 1996 pages 86 (prof curv) and page 115 (max/min curv). This may be describing only a special case. max/min curv is described as the maximum/minimum curvature (in any plane) so maybe use calc across a stack of curvatures and apply max and min as the functions.

I believe this is also an issue with mean curvature

ailich commented 2 years ago

calc method is incorrect. Edit code based on r.param.scale source code.
