Need help with water drop pattern on vase

[Mara_Silva]

Hello, I am doing some experiments with a ceramic 3d printer and I wanted to create a vase mimicing the pattern of a drop in water, luckily I found a tutorial https://youtu.be/MzDwjAEmavU?si=cCtKQRByhHe6dDQD the problem is, i want to do it all on grasshopper but don’yt know how.

From what I’ve tried my main issue is the points not moving parallel to the normals(?).

I’ve also tried something to the tutorial and afterwards getting the pattern on the cylinder surface but was unable to…

here’s the main idea

Here’s what I made

Can someone help and explain what I’m doing wrong please?

Thank you

Explaining costs extra. Is this close? There is an unresolved issue keeping the new surface (green group) tangent at the seam…

P.S.

I changed your code and started to “fix it”

But decided for now to share the same with only slightly more visible geometry:

P.S. Iso Curve looks odd

didn’t look at your file, but you aim for something like this?

[Birk_Binnard]

Maybe something like this?

P.S. Iso Curve looks odd

This was a simple error - forgot to reparameterize the ‘S’ (surface} input of Iso Curve.

No reply? Done then!

[Mara_Silva]

That’s exactly what I’m trying to do! But I’m failing miserably

[Mara_Silva]

That’s not quite was I was looking for but honestly it looks better than everything I did, thank you for the help

have a look at this core function, it should get you somewhere.

(just don’t put your influence points right on the surface you are dividing to get the point grid, there needs to be a little distance for falloff function to work well)

lofting periodic curves is preferable to srf from pts.
