This is an experiment in flocking boid simulations using (Processing)[https://code.google.com/p/processing/], OpenGL, and (Scala)[http://www.scala-lang.org/].
The code is inspired (and partially derived from) similar simulations written in Javascript and published by (Mr. Doob)[http://mrdoob.com/].
Also included are a set of implicit type convertions to make the Processing vector library work with regular mathematical operators, keeing correct operator precedence.
To make this work cross platform, I bundled a build of JOGL, Processing, and an audio library called Minim. To setup these bundled dependencies, run the included setup.sh or manually extract deps.tar to the lib folder.
Note: Unfortunately the snapshot of Processing I build requires Java 1.6 to run.
Since building scala with SBT is a PITA, and Oracle and Apple have made it near impossible to get a 1.6 JDK on OS X, I have included a simple pre-build of the app that gets setup when you run setup.sh.
The included mp3 was sourced from (Last FM)[http://www.last.fm/music/+free-music-downloads]. If our tastes in music differ, you can replace it with one of your choosing :).
Do this:
setup.sh
show-birdies.sh
To build from source, you will need to have either (SBT)[http://www.scala-sbt.org/] installed, or Eclipse + the (Scala plugin for eclipse)[http://scala-ide.org/].
With SBT (and java 1.6!) you can compile and run the demo via sbt run. For Eclipse users I have bundled a sample .project and .classpath that you can load in the IDE.
