JS.Perlin

forked from https://github.com/arcanis/js.perlin and made into a simple commonjs library

npm install perlin

Usage

  • require('perlin')( [ table ] )

Returns a new generator instance. If table is set, then it will be used as random lookup table otherwise a random table will be generated.

  • [instance].octaves
  • [instance].frequency
  • [instance].persistence

Generator configurations variables.

  • [instance].generate( start, size, callback )

This function will call callback() for each pixel in the N-dimensional range between start and start+size, with two parameters : the coordinates of the current pixel, and the related Perlin value.

var generator = require('perlin')( );

generator.generate( [ 0, 0 ], [ 2, 2 ], function ( point, value ) {
    console.log( point, value );
} );
