Find each Crest/Trough of a wave-like curve

[ctu6]

Hi all,

I have a interpolate curve,
Is there a way to find each Crest/Trough (obvious by seeing) of a wave curve?
Describe as image below.

Fennec plugin has Extremes component.

Thanks @HS_Kim

That’s exactly what I want,
but before download another plugin (since I already installed a lot …)
is it possible to have another way to do so?

Find the local exteremes of a periodic boundary

Hello Everyone, I’m looking for a way to find the local extremes of a periodic boundary. When I choose to work with periodic boundary the extremes can be found in several directions (I used RhinoCurveExtremeParameters method). Does anyone have any idea how to find local extremes of a periodic curve without optimization solvers? P.S I’m not sure if those points are called local extremes. Best, Mahan [Periodic boundary]
