iPhone Location Data

For those of you who haven't yet heard, Apple are tracking your every move. As somebody who has nothing to hide ( hopefully ), I thought I'd share an experiment I'd carried out using some of my own location data and OpenHeatMap. Apple store triangulated data based on nearby cell masts and not based on GPS which is a slight shame because the accuracy isn't great. Here is a greatly speeded up video of my actions since December 2010.

Aerodynamics for Convex Hulls

I had quite a nice thought experiment and thought I'd document it for you guys to have a look at. I wanted to come up with a quick way to (semi) realistically simulate lift and drag on any shape. Such an engine could be used for flash games for example a hang glider game. Realism like this (if carefully implemented) can add a lot to a game.

I plan on implementing this in flash sometime after my exams are over, but some of you might be interested in my approach, so feel free to beat me to coding it!

Here is what I've got so far, you can click on a page to expand it in a lightbox (or click here to download the pdf):

Fun with Inverse Kinematics

In part to try out AXDT, a flash plugin for Eclipse (which you can find here), I decided to create a simple experiment involving Inverse Kinematics. This is not a very useful implementation but the results are quite fun. Essentially, the angles of subsections of  each kinematic chain are altered until they face the mouse. I quickly discovered this is not the best solution for IK, but just for fun I made a kind of windswept, fur or grass effect using about 200 IK chains.
