permutiation (numbers[]) is an optional parameter to set the permutations used by the system

.noise

perlin.noise(x: number, y: number, z: number, min?: number, max?: number)

x (number) X cordinate

y (number) X cordinate

z (number) X cordinate

min (number) not required, default 0. Minium value generated.

console.log(perlin.noise(0.1, 0.1, 0.1));

Credits

This is a port of Kas Thomas' javascript function which is a port of Ken Perlin's Java code. Kas Thomas' code can be found at https://asserttrue.blogspot.com/2011/12/perlin-noise-in-javascript_31.html Ken Perlin's code can be found at http://cs.nyu.edu/%7Eperlin/noise/ So really most of the work was done by them, I simply ported Kas' version to typescript by adding a few types to the functions
