Lecture 07 – Interactive OpenGL

This session reminded us that interaction seems to happen in the head / eye / ear / heart of the beholder and not so much within the systems we often tend to call interactive.

We looked at Jitter’s ability to synchronize perfectly with sound by generating sound and image from the same LFO (low frequency oscillator) basically a very slowly moving stream of numbers.

We took as our starting point Andrew Benson’s Jitter Recipe 00-LFO.  You can download this from here; cycling74.com/2006/02/06/jitter-recipes-book-1/.  This an excellent  collection of Audio-Visual programming examples that are well explained.  Understanding this first one is key to the session but to get the best of these you will need to have some basic understanding of Jitter and how it works.
