banksean / mersenne-twister.js
Created Feb 10, 2010
a Mersenne Twister implementation in javascript. Makes up for Math.random() not letting you specify a seed value.
View mersenne-twister.js
/*
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 Feb 15, 2010
two Perlin noise generators in javascript. The simplex version is about 10% faster (in Chrome at least, haven't tried other browsers)
View perlin-noise-classical.js
// 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.
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 });
