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.

CSS for <sub> and <sup>

	sub, sup {
	/* Specified in % so that the sup/sup is the
	right size relative to the surrounding text */
	font-size: 75%;

	/* Zero out the line-height so that it doesn't
	interfere with the positioning that follows */
	line-height: 0;

	/* Where the magic happens: makes all browsers position

	// A short snippet for detecting versions of IE in JavaScript
	// without resorting to user-agent sniffing
	// ----------------------------------------------------------
	// If you're not in IE (or IE version is less than 5) then:
	// ie === undefined
	// If you're in IE (>=5) then you can determine which version:
	// ie === 7; // IE7
	// Thus, to detect IE:
	// if (ie) {}
