I've started putting up some of my Processing/Java tidbits to GoogleCode (it was simply easier/faster to setup than sf.net). This is not a collection of libraries, but a slowly growing SVN repository of classes I've written over the past year or so and been finding myself re-using a lot. A couple of them are still quite buggy too, unfortunately.

So please consider this more of a heads up rather than an official launch. Some of the stuff is not usable from within the default Processing IDE, some classes rely on the "new" Java5 syntax features, but still might be helpful to somebody (e.g. Eclipse users). Included in this loose collection are general purpose classes like:

   * a comprehensive 3D Vector class with many methods available in mutable and unmutable versions. It also has some basic collision/intersection testing methods included which I needed for the Audi project above. Javadoc is incl. in the download.
   * wave oscillators. All based on a common framework, new wave types can be added easily.
   * greyscale image filters used by the newer version of my libcv library.
   * colour palette utilities
   * etc.

Have a browse through and let me know any probs via the issue tracker...
