The beauty of Processing is that this was basically a doodle — it took only about 10 sustantial lines of code to write.

Fractal Audio Wavetables in Processing

J.D. Northrup — Wed, 11 Mar 2009 06:23:25 +0000

This is a Processing implementation of the fractal wavetable algorithm I mentioned in previous posts.

The Processing framework itself is really nice — very easy to get into and start hacking out ideas. I’m using the Ess sound library to handle audio playback.

Here’s a link to the sketch. This should play in most Java-equipped web browsers:

Update: See FractalWavetables v2 for new options.

Dancing Spirals Screensaver

This is 3D OpenGL eye-candy for Mac OS X, complete with customizable settings, and full source code.

The implementation might be interesting – the options interface is build using Interface Builder, Objective-C and Cocoa, yet the actual drawing code all happens in C++ using OpenGL.

Props to the folks at Cocoa Dev Central for posting a pair of tutorials that got me started with building screensavers in Xcode.
