Local Optima In mathematics and computer science, there is a concept called local optima. In short, the easiest to achieve solution (local optima) isn’t always the best solution (global optima). A nice metaphor for this concept is the Hill Climbing algorithm. Imagine that you wake and find yourself in a featureless world. Because of a dense fog, you can only see a few meters in each direction. In

A few months ago, the Barbarian Group was approached by Erasmus to help with promotions for the Relentless Energy Drink. Relentless, available only in the UK, is a frequent sponsor of music festivals and sports competitions. They asked us to make an audio visualizer that would run in real-time so they could show it at these venues. In addition to the live application, they wanted a content creatio

Barbarian Group + Nervo = Awesome! More often than not, the pipeline for a project gets overshadowed by the end result. The process of getting from point A to B is often overlooked because point B is just sooo damn sexy. But it doesn’t have to be that way. No really, it doesn’t. A couple months ago, Nando Costa approached Barbarian Group and asked if we would help out with a project his new motion

For this first release, I am showing how I go about making a generic particle emitter. I used Processing v.135 and Karsten Schmidt’s Vec3D library. It was developed on a MacBook Pro laptop, but this shouldn’t be a problem. There is an emitter on screen which will follow your cursor position. When you click and hold the left mouse button, it will create particles with a randomized velocity and sen

Return of the birds! Finally! Here is the video that a few of you asked to see. The original post of this project was about three months ago. I had always meant to make a video of it, but just didnt get around to it. But here it is (Vimeo only for now). Also, found another neat trick. Reflective mapping with OpenGL. It ended up being a fairly easy trick, and it adds extra ooomph to the ripple code

I tend to avoid trying new things until the last minute. I usually have to be dragged kicking and pouting into new technology or a new way of thinking. However, if I need to learn something new for a client, though I will still kick and pout, I find the threat of a shitty deadline is just the thing to allow me to dive into something new. JBox2D is the new thing that is occupying my time these days
