/**
 * \brief Returns positional offset for a given point as a result of summing 4 gerstner waves 
 * \param positionWS point in world space
 * \param wavelengths wavelength of each of the 4 waves
 * \param amplitudes amplitudes of each of the 4 waves
 * \param directions direction of each of the 4 waves (each row = one direction). MUST BE NORMALIZED!
 * \param speed global speed multiplier. Individual wave speed depends on Wavelength
 * \param steepness Gerstner wave 'Steepness' parameter. Modulates the horizontal offset of points
 * \param normal returns the normal of given point.
 * \return positional offset of the given point

Conventions

• A = [xA, yA] is a point on the 2D plane. Same for B, C, ...
• lengths are in any unit (ex: pixels)
• code snippets are in JavaScript

Degrees to radians

angleRad = angleDeg * Math.PI / 180;

I made an HTML port of game of life made with a table of checkboxes based on Pluralsight's Play by Play: HTML, CSS, and JavaScript with Lea Verou (http://www.pluralsight.com/courses/play-by-play-lea-verou). I was able to create a cool mousedown interface that allowed the "player" to draw on the board by dragging the mouse while it was down, and wanted to do the same for touch devices.

Unfortunately, touch events only hold references to the DOM element where they began (i.e. where "touchstart" fired) and do not recognize the DOM elements that exist under them (a detailed explanation for this can be found here: http://stackoverflow.com/questions/4550427/prefered-alternative-to-onmouseover-for-touch).

Instead, touch events maintain several lists of Touch objects - which represent interactions with the touch screen. Among these objects' properties are clientX and clientY, which indicate the X and Y coordinates of the events relative to the viewport (go to http://www.javascriptkit.com/javatutors/touchevents.shtm

Testing IE 7/8/9 on OSX

Steps needed to start IE7/8/9 testing on OSX with VirtualBox

• Download and install VirtualBox (https://www.virtualbox.org/wiki/Downloads)
• Download the free VPC images of IE versions you need from Microsoft (http://www.microsoft.com/download/en/details.aspx?id=11575)
• For each image, extract the auto-unarchiving .exe. Zipeg was tested and it worked (http://www.zipeg.com/)
• Open the extracted VHD in VirtualBox
• In VirtualBox change the Storage settings: Settings --> Storage --> Remove the drive from under SATA and add it under the IDE driver.
