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?
Traditional Geometry Nodes for a curve.
Thanks for your time and help ;)
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.
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.
