                                         double persistence)

Description copied from class: PerlinOctaveGenerator

Generates multiple layers of noise.

Overrides:

getFractalBrownianMotion in class PerlinOctaveGenerator

Parameters:

x - the starting X coordinate

y - the starting Y coordinate

z - the starting Z coordinate

lacunarity - layer n's frequency as a fraction of layer n - 1's frequency

persistence - layer n's amplitude as a multiple of layer n - 1's amplitude

Returns:

The noise array
