Fast Noise Configs

Lithostitched introduces a fast_noise density function type to sample FastNoiseLite (FNL) objects. Fast noise configs determine the configuration of these FNL objects, similar to how vanilla noises need noise configs defined in worldgen/noise.

Fast noise configs are stored in the lithostitched/fast_noise_config folder of the data/(namespace) folder. This means that a fast noise config with the identifier foo:bar is stored in data/foo/lithostitched/fast_noise_config/bar.json.

Here's an example fast noise config:

{
  "type": "lithostitched:cellular",
  "frequency": 0.002,
  "salt": 304658814,
  "distance_function": "euclidean",
  "return_type": "cell_value",
  "jitter": 1
}
