How to make water ripples gently blend into flat surface?

I would like to make something similar to this serving tray. I have found a grasshopper file that allows me to make the water ripples I am wondering how to effectively take the water ripples and have them seamlessly blend back into the flat surface of the object. I would like the transition to appear more natural and gradual then the serving tray but I am not sure what the best approach is. I would prefer to construct it parametrically if possible but at this point if it is easier and more practical to model it myself I will. What are your thoughts.

Hello - I don’t know if this is what you mean - but maybe?

I believe so. I was able to see the image and it looks correct but I have rhino 5 and wasnt able to open it. Is there anyway that I could see the grasshopper file that allowed you to create it?

Oddly, my thoughts is that that could also be easily made by revolving a simple curve, and cutting out the parts you don’t want.

I understand the Grasshopper adaptability is cool, and at the same time, I feel that Rhino’s ordinary modeling tools are so intuitive that this particular application seems like a thought experiment.

That is what @pascal did if you open up his file.

I guess a lot depends on whether you want a realistic “stone dropped in water” set of ripples. They don’t look like simple sine waves…
As I understand it the maths involved is complex so it may be easier to study some photos and draw an approximation than to try and use grasshopper.


You can change the graph type to sinc.
