    r"""
    Generate fractal noise which can be thresholded to create binary
    images with realistic structures across scales.
    Parameters
    ----------
    shape : array_like
        The size of the image to generate, can be 2D or 3D.
    frequency : scalar, default=0.05
        Controls the overall scale of the generated noise, with larger
        values giving smaller structures.
    octaves : int, default=4
        Controls the number of scales across which structures are
        generated, with larger values giving more scale.
    gain : scalar, default=0.5
        Controls the intensity of successively higher octaves. Values
        below 1.0 mean the higher octaves are less prominent.
    mode : string
        The type of noise to generate. Options are:
        ========== ==================================================================
        mode       description
        ========== ==================================================================
        'perlin'   Classic Perlin noise. For more information on ``perlin noise`` see
                   `here <https://en.wikipedia.org/wiki/Perlin_noise>`__.
        'simplex'  Updated Perlin noise for more realistic textures. For more
                   information on ``simplex noise`` see
                   `here <https://en.wikipedia.org/wiki/Simplex_noise>`__.
        'value'    Bilnear interpolation of white noise. For more information on
                   ``value noise`` see
                   `here <https://en.wikipedia.org/wiki/Value_noise>`__.
        'cubic'    Cubic interpolation of white noise. For more information on
                   ``cubic noise`` see
                   `here <https://github.com/jobtalle/CubicNoise>`__.
        ========== ==================================================================
    seed : int, optional
        The seed of the random number generator.  Using the same
        ``seed`` between runs will produce the same image.
    cores : int, optional
        The number of cores to use. This function uses ``pyfastnoisesimd``,
        which has implemented SIMD processing which can be spread across
        cores. The default is to use all cores.
    uniform : boolean, optional
        If ``True`` (default) the random values are converted to a
        uniform distribution between 0 and 1, otherwise the resulting image
        contains the unprocesssed values, which have a 'normal-esque'
        distribution centered on 0.
    Notes
    -----
    This function provides a simplified wrapper for the functions in
    the `pyfastnoisesimd <https://github.com/robbmcleod/pyfastnoisesimd>`_
    package. ``pyfastnoisesimd`` is itself a wrapper for a C-library
    called `FastNoiseSIMD <https://github.com/Auburn/FastNoiseSIMD>`_.
    To access the more elaborate functionality and options of these
    packages, explore the `pyfastnoisesimd documentation
    <https://pyfastnoisesimd.readthedocs.io/en/latest/overview.html>`_.
