Value noise is a simpler version of cubic noise that uses linear
interpolation between neighboring grid points. This creates a more distinct
smooth checkerboard pattern than cubic noise, where interpolation takes all
the surrounding grid points into accout.

## Arguments

dim |
The dimensions (height, width, (and depth)) of the noise to be
generated. The length determines the dimensionality of the noise. |

frequency |
Determines the granularity of the features in the noise. |

interpolator |
How should values between sampled points be calculated?
Either `'linear'` , `'hermite'` , or `'quintic'` (default), ranging from lowest
to highest quality. |

fractal |
The fractal type to use. Either `'none'` , `'fbm'` (default),
`'billow'` , or `'rigid-multi'` . It is suggested that you experiment with the
different types to get a feel for how they behaves. |

octaves |
The number of noise layers used to create the fractal noise.
Ignored if `fractal = 'none'` . Defaults to `3` . |

lacunarity |
The frequency multiplier between successive noise layers
when building fractal noise. Ignored if `fractal = 'none'` . Defaults to `2` . |

gain |
The relative strength between successive noise layers when
building fractal noise. Ignored if `fractal = 'none'` . Defaults to `0.5` . |

pertubation |
The pertubation to use. Either `'none'` (default),
`'normal'` , or `'fractal'` . Defines the displacement (warping) of the noise,
with `'normal'` giving a smooth warping and `'fractal'` giving a more eratic
warping. |

pertubation_amplitude |
The maximal pertubation distance from the
origin. Ignored if `pertubation = 'none'` . Defaults to `1` . |

x, y, z |
Coordinates to get noise value from |

seed |
The seed to use for the noise. If `NULL` a random seed will be
used |

... |
ignored |

## Value

For `noise_value()`

a matrix if `length(dim) == 2`

or an array if
`length(dim) == 3`

. For `gen_value()`

a numeric vector matching the length of
the input.
