Hello
there are surely many ways to replicate this.
What it reminds me is this post with the growth inverted top to bottom here.
In order to make the growth I put circles on a surface, circle growths (radius, length) if there is enough place and the direction is attracted by Z vector. This need some coding.
If you want some tools to do things like that some Agent based could be the solution. Culebra could be one
More simple ways could also be used like this one
I also think of a simple solution but it also depend on what you need exactly. Is it just rendering ? 3d printing ? Do you have some initial shape to make it growth ? …
