    JS.Perlin

    Installation

    npm install js.perlin

    Usage

    • new 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 Perlin = require( 'js.perlin' ).Perlin;
     
    var map = new Perlin( );
     
    map.generate( [ 0, 0 ], [ 2, 2 ], function ( point, value ) {
        console.log( point, value );
    } );

    To do

    I need to :

    • Understand why implements Perlin.random as Math.random( ) * 2 - 1 just doesn't work.

    • Implement real Perlin noises (standard & simplex).

    If you can help me on one of these two issues, please feel free to post an issue and / or make pull requests !
