OK, I admit it - curvature isn’t my ballpark.
What I want to do is to highligt “sharp” convex curvature, like when a surface with thickness folds around the edges from the outside to the inside surface. Simplified illustration below (not a mesh though) shows how only the ridge along the red line should be hightlighted:
The actual mesh I’d like to apply the curvature analysis to has holes, and I would like to highligt the “ridges” of the edges of those holes, preferably without gradients on the lesser curved areas/surfaces (the selected faces):
My problem is that I have not found any single curvature method that does this highlightning consistently enough (probably due to my lack of understanding & experience of curvature analysis), but I imagine that perhaps a combination of curvature methods would isolate exactly the desired extreme curvatures?
Isolating faces (or vertices) with extreme “positive cylindric” curvature seems to be what I’m after (while “double” curvatures like hyperboloid or ellipsoid are less relevant).
I’ve tried using the MeshCurvature plugin but I have failed to get a pure and consistent highlightinbg all the edges with steep change in curvature (sharp creases aside). Example result with very “shattered” or spotted highlightning:
I want the face indicies of these edges. Example mesh attached:
