White noise is a random noise with equal intensities at different
frequencies. It is most well-known as what appeared on old televisions when
no signal was found.

noise_white(
dim,
frequency = 0.01,
pertubation = "none",
pertubation_amplitude = 1
)
gen_white(x, y = NULL, z = NULL, t = NULL, frequency = 1, seed = NULL, ...)

## Arguments

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

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

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, t |
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_white()`

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

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

. For `gen_white()`

a numeric vector matching the length of
the input.
