Loaded as one of the noise expressions listed in this union, based on the value of the type
key.
A fragment of a functional program used to generate coherent noise, probably for purposes related to terrain generation.
Noise expressions can be provided as table literals or built using functions in the built-in noise library. The built-in noise library allows writing much more concise code, so its usage will be shown in most examples for noise expressions.
noise.define_noise_function allows noise expressions to be defined using a shorthand that's a subset of Lua (see the example for details).
See here for a tutorial on authoring noise expressions.
