this is my recent audio reactive experiment. the idea was to make shapes only visible through their silhouette and rays of light discribing those shapes in a decent way.
So basically the whole piece is based on a volumetric light scattering effect done in GLSL. the whole thing runs realtime at 720p resolution. Framerate is put to 30 FPS.
If anybody has information about how to make visualizers for itunes please let me know, google could not really help me on that.
The song is Der Buchdrucker by Dominic Eulberg (I only took a short piece of the song, the original is approx 9 minutes)
The original is actually not that dark. As you might see in the screenshots there is some more cloudy tmospheric effects in the real thing!
