Usage

The globally exported Heightmap class contains the static create method. This generates a heightmap represented as a square array of numbers between 0 and 1 with size 2 ^ n + 1.

The method uses the Diamond-Square Algorithm. An iterations argument is required to set the amount of iterations of the algorithm, which corresponds to n in the size formula.

For example, Heightmap.create(2) will create a heightmap of size 5.
