• [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 = new PERLIN.Generator( );

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