AntoineSfx Posted July 4, 2018 Share Posted July 4, 2018 (edited) This is not really a Houdini question, but does the notion of local minimum exist in 3d, without assumption on the geometry ? Except that it is not degenerate, no self intersection; basically a closed well formed surface. For example, to find protrusions and recesses on a mesh I was thinking of something like looking at where the neighboring points of each point at located with respect to the local normal plane, within a certain distance.

MENOZ Posted July 4, 2018 Share Posted July 4, 2018 I would say is the laplace operator https://www.khanacademy.org/math/multivariable-calculus/multivariable-derivatives/laplacian/v/laplacian-intuition Quote Link to comment Share on other sites More sharing options...

It should be interesting Quote Link to comment Share on other sites More sharing options...
