banksean / mersenne-twister.js

Created February 10, 2010 16:24

a Mersenne Twister implementation in javascript. Makes up for Math.random() not letting you specify a seed value.


	/*
	I've wrapped Makoto Matsumoto and Takuji Nishimura's code in a namespace
	so it's better encapsulated. Now you can have multiple random number generators
	and they won't stomp all over eachother's state.

	If you want to use this as a substitute for Math.random(), use the random()
	method like so:

	var m = new MersenneTwister();

banksean / perlin-noise-classical.js

Created February 15, 2010 10:00

two Perlin noise generators in javascript. The simplex version is about 10% faster (in Chrome at least, haven't tried other browsers)

	// Ported from Stefan Gustavson's java implementation
	// http://staffwww.itn.liu.se/~stegu/simplexnoise/simplexnoise.pdf
	// Read Stefan's excellent paper for details on how this code works.
	//

	/**
	* You can pass in a random number generator object if you like.
	* It is assumed to have a random() method.

An Albers Equal Area Conic projection in javascript, for protovis.

	/*

	An Albers Equal Area Conic projection in javascript, for protovis.

	For centering the contiguous states of the USA in a 800x400 div, I used:

	var scale = pv.Geo.scale(albers(23, -96, 29.5, 45.5))
	.range({ x: -365, y: -375 }, { x: 1200, y: 1200 });
