Perlin Noise corrosion study.

A custom python script that creates perlin volumetric noise in any given closed geometry. The idea is adapted from The Nature of Code Processing book by Daniel Shiffman.

Axis system for noise, granularity and density can be set up from the Grasshopper definition

For the script to work the Perlin Noise python library needs to be on the local computer and Rhino needs to be aware of the it.

You can start the EditPythonScript command in Rhino and from Tools->Options you can set up a load path that points to the library.

You can get the library from here.
