A while back I made a simple volumetric light demo in Luster. I just wanted to test the rendering technique. Colin then picked it up and decided he would make the light pulse to the beat of the music by doing some audio processing in Flash and sending commands back out to Luster. Turns out, it worked really well. I put in similar audio processing capabilities into the core Luster API and pretty soon that simple volumetric light demo became our first music visualizer.

This is the second visualizer we’ve made. This one focuses more heavily on particles, with a lot of action going on at once. There’s a vignette-style blur post-processor as well as healthy amounts of bloom. Almost everything in this application is affected by the music, including the camera movement, the particle motion, and the return of the spectrum targets from the first visualizer.

We haven’t uploaded this application to the beta tech demos section yet. Videos, screenshots, and the app itself will soon be on the Luster3D site. All music in the video is from Jason Mraz. Also, if you view the video on YouTube you can see the high-def version, which I recommend doing.
