A utility class providing noise functions.
The code is based on Simplex noise demystified by Stefan Gustavson, 2005.
Import
SimplexNoise is an addon, and must be imported explicitly, see Installation#Addons.
import { SimplexNoise } from 'three/addons/math/SimplexNoise.js';
Constructor
new SimplexNoise( r : Object )
Constructs a new simplex noise object.
r
A math utility class that holds a random() method. This makes it possible to pass in custom random number generator.
Default is Math.
