Im sure I’ve e seen a GH def for a pattern like this but i cant find it anywhere on either forum now. Similar to the wave interference patterns but it lioks more like a force field / height field than the water drop interference patterns. Can anyone locate a link or suggest any info to help me cre…

Ah ! yeah, that is a great idea !

Hello Laurent. Just wanted to let you know that your definition works beautifully if you X+1 the UV input on a mesh from points node and plug it into a SubDiv from mesh component. Its lightning fast.

Is there a way for this to work on a plane that’s not square? For example, if I wanted to fit this to a specific closed curve, would that be possible? Also, is there a way to control where the center points are? I’m pretty new to grasshopper. Sorry if I’ve missed something that’s already been expl…

[image] andrea.guillen001: Is there a way for this to work on a plane that’s not square? Planes are infinite, you probably mean surface. Ripple a rectangular planar surface, then project the curve to that surface and trim (split) it?

[gh] Thanks for the quick response! Im trying to make it work with this shape. I guess I should rephrase what I mean. Is there a way to make it work so that I dont have truncated ripples on the edges? (Imagine them being squished against the edge rather than trimmed)

Yellow group. Had you posted your own GH code and geometry, I would have used it instead. [undulating_surface_2021Jul14a] undulating_surface_2021Jul14a.gh (27.0 KB) P.S. I left out Fillet by accident, you might want to add it back. P.P.S. This code has been hacked several times, I barely rem…

I tried this but was given an error. I really appreciate all the help :smiley: [error] Surface.3dm (59.6 KB) undulating_surface_2020Feb25b.gh (20.6 KB)

Unable to open R7 .3dm file in R6. You could internalize your geometry? Would have been better to have this in your first post. Forget the parts in my code that ripple the surface, use yours instead!

Let’s try this again. Replace the gray group with your own “force field” ripple code, generating values in the ‘0 To 1’ range, and replace the ‘Edge Crv’ with your own geometry. Note the effect of Untrim to get a base rectangle. If that doesn’t work, try ‘Surface | Primitive | Plane Through Sha…

Describe this force field type pattern please
