This file is for the CellNoiseGenerator. This generator generates tendrils of blocks using cell noise skewed with simplex noise. This generator is multithreaded. Constructor: Notes: This constructs a CellNoiseGenerator that generates air blocks. Constructor: Arguments: ItemBlockData Argument Usage: block to generate Notes: This constructs a CellNoiseGenerator. openTop: Notes: Sets the generator to scale noise in such a way that tendrils will taper off towards the top of the dimension. This is set by default. closeTop: Notes: Sets the generator to scale noise in such a way that a roof will be generated at the top of the dimension.
