With Geometry Nodes I am able to create a curve with specific points.

Now I would change the traditional curve profile for a custom one.

How can I define one like this?

One solution is to set the radius on the bezier curve before handing it to the curve-to-mesh node. Input to this radius can be a function that will provide your "dents". Here are the relevant edits to your blend.enter image description here

Which gives you this, enter image description here

I use a clamped sine wave for the dents, obviously not perfect, but you get the idea. Note that you need more resolution in the bezier curve.

  • $\begingroup$ Thank you for your reply. I never thought of solving the problem this way. Anyway, I would have liked to be able to control the result more in order to put shapes more iregular. Sorry for my awfull english :( $\endgroup$ Mar 24, 2023 at 8:25

Instead using the GN 'Curve Circle' you can use 'Curve on Points' combined with 'Instance on points' to fill the curve with instances of a mesh. Result and GN
