constructor

new SimplexNoise(randomOrSeed?): SimplexNoise
Creates a new SimplexNoise instance. This involves some setup. You can save a few cpu cycles by reusing the same instance.
Parameters
- randomOrSeed: string | number | RandomFn = Math.random
  A random number generator or a seed (string|number). Defaults to Math.random (random irreproducible initialization).
Returns SimplexNoise
