I am looking for a method to create a circular shape that has a sine wave as an edge. Like the picture I posted in addition to this question. I want the edge to be a sine wave and the rest of the surface to be warped.
I assume that you need not only the outer edge, but also a nice topology inside the shape.
Maybe this example will help you:
As basis I use here a mesh, which I created from two curves with
Curve to Mesh.
This has the advantage that I can divide it on two axes into as many segments as I want.
With a few math nodes I capture the points concentrically and radially and can move their positions accordingly.
So that the flow of the mesh remains adjustable also to the center, I use here additionally the node
The advantage of this solution is that it creates a mesh that is built up with quads, so you can additionally apply a subdivision.
