recompute point normals based on curvature

[KristianZarn]

Hello

I am trying to do a fence over a small hill. The idea was to lay some points on the hill and then place a pole on each point (oriented like the point normal).

This is what i have now:

 

but i want the points normals to correspond to hill curvature, and not just point straight up.

something like this:

 

Is this possible?

Sure it is. How are you getting the curve on the surface? If it's with a ray sop, there's a checkbox to inherit normals, forgotten it's actual label, but it will be obvious. Otherwise you can transfer the normals with an attribute transfer sop (use a facet to calculate normals if there's no N attribute on your hill geo), or even a facet on the curve if it's a polygon curve. Loads of ways...

Yup, I am using the ray sop for the curve and the checkbox i found with your help is "Point intersection normal". Thank you.
