Challenge for the math-heads out there

Curious how someone would approach trying to procedurally generate a displacement that is reminiscent of something like this:

(or this: Wingham Brush Nature Reserve | Moreton Bay Fig tree in Wingh… | Flickr or even this: https://pics.davesgarden.com/pics/2005/01/02/Kylecawaza/388cc5.jpg)

I’m concerned with the trunk of the tree, not the crazy branching roots. Seems like the perlin noise 4d add-on might be useful (4D Noise | Food4Rhino) but I’m not sure how to stretch that along the y-axis.

Basically I’d like a ‘wall’ that has the look of that kind of fig-tree trunk…

Any and all thoughts appreciated!!!

Dang, nobody? Well, failing that, is there anyplace else on the web where I might find someone who’d be able to dig in on this with me a little?

Huge circular Victoria Amazonica lilly leaf pattern

Hi here an awful script to do that [image] [image] There are many logics it it. First generate the pattern [image] The division of curves uses the equation here but the equation is false it is A(n) = 5 * 2 * n -2 The curve Network is smoothed (my equation) not sure it will stay long on this forum. [image] Upper part is used the make the ribs Main logic is to extract inner parts, measure their lengths and cut them in quite equal lengths parts [image] [image] The whole other …

ahhhh, very nice! my faith in this forum has been restored
I’m actually away from my rhino-installed computer for another couple of days but will dive in when I get back.

Thanks thanks thanks for helping out with this!
