def
get_simplex_noise(rows, columns, *args, **kwargs):
Get a simplex noise image
Parameters

- columns: The number of columns
- args: The arguments to pass to the simplex noise function (see
add_simplex_noise()) - kwargs: The keyword arguments to pass to the simplex noise function
Returns
The simplex noise image

add_simplex_noise( dataset: numpy.ndarray, frequency=0.01, octaves=4, persistence=2.0, amplitude=1000.0, offset=1000.0, seed=-1):
Add simplex noise to a 2D numpy array.
Parameters
- im: The 2D numpy array to add noise to.
- frequency: The frequency of the noise.
- octaves: The number of octaves to use.
- persistence: The persistence of the noise.
- amplitude: The amplitude of the noise.
- offset: The offset of the noise.
- seed: The seed to use for the noise generator, if -1 a random seed will be used.
