ANIMATION DESCRIPTION:
Lights appear and rise with each note played on the piano. The brightness of the lights and how long they glow approximate the perceived loudness of the notes.
DESCRIPTION OF HOW THIS ANIMATION WAS CREATED:
I composed and recorded the piano piece using Cakewalk Home Studio sequencing software and my Kurzweil PC2 keyboard. I saved the song in MIDI and WAV formats. I wrote a Perl script and used the MIDI-Perl library to parse the MIDI file and generate a simple POV file to be rendered. After rendering the frames in POV-Ray I used Dave's Targa Animator to create an .AVI animation file. Finally I used TMPGEnc to combine the .AVI and .WAV files into the final MPEG with sound.
