<description>
|
|
This class generates noise using the FastNoiseLite library, which is a collection of several noise algorithms including Cellular, Perlin, Value, and more.
|
|
Most generated noise values are in the range of [code][-1,1][/code], however not always. Some of the cellular noise algorithms return results above [code]1[/code].
