I have seen pictures of water ripple textures on the internet, it is the effect of using plane curves utilizing CNC machining, I don’t know how these plane curves are generated;
I have tried to create some plane curves myself and it is not ideal;
please share you .gh of what you already have. I think all these examples are just contour curves slicing a deformed surface, although could also be achieved with tweening curves
although your reference image doesn’t really look like a water ripple,
you can get a water ripple effect by combining sin waves
