| I like Achims State machine, here's another approach I made years ago before my JS was useful. I've done this sort of thing where I have two registers and interpolate between them. The registers are the two most recent items in a queue, so a new item in pushes the registers if that makes sense. Can't find a composition for that method. Also I did it for a structure of 3D attitudes/orientations of an object. I have a comp for this. In this case the queue just track random index values, again causing the index at the registers to shift along each time a new one comes in. It's a juggling act that uses a pulsed timer (LFO sawtooth-ramp-up) to drive interpolation patches and the queue; here is a demo composition I dug out (minus the interesting bit that morphs a cube into a sphere and back). |

NB The rotation position.plist is an XML file that needs to be in the same folder as the comp to load. Best Alastair On 17/06/2011, at 5:09 PM, Rick Mann wrote:
