Code and images within the main branch of this repo were originally created by Jasmin Sadegh, Annie-Locke Scherer, and Rebecca Jaroszewski. See here for more information.
coral_growth.py can be used as a python module with Rhino/Grasshopper to "simulate" branching coral growth. The method of simulation uses Random Walkers. Note that this is only meant to mimic the general structure of a branching coral, not the underlying biological mechanism as is done in Jaap Kandorf's work. In the figure above you can see conceptually how "branching" occurs with Random Walkers acting as food.
Here is a .gif displaying the original code working in Grasshopper:
