    Oh my, I must have a play with that Kineme patch!

      The Kineme patch just does the line. Having said that, you could actually do the whole thing just using a single Kineme Line Expression patch. I’ve done the maths in JavaScript because I’ve always been confused by the syntax of the Line Expression patch.

    Although this is obviously enough a JavaScript Array, I guess this isn’t simply a lissajous array set being pushed?

    Looks really nice & clean, can’t wait for the video, [ but gonna have to :-)]

    I like those automatically generated associated links BTW 🙂

      Hiya.

      The Lissajous equatations are based on a time value, so I just loop around a range of time values per-frame, adding the resulting X Y and Z values to a two-dimensional array, which is then fed directly into a Kineme Line Structure patch.

      I’m going to do some 2D variants, rationalise the controls, then I’ll do a little demo movieclip, if I get a chance.

      I like the Lissajous Web pics- they’re really nice. I wonder what the logic is for joining the points together with that one.

    Lissajous curves are great. They offer lots of opportunities for fun audio visualization stuff. I wrote an iTunes pluggin that uses them in one of its modes. Here’s a sample video:

    If you’re interested the visualizer is called Manifesto and can be found at:

    Hey, pretty cool tb! I’ve always done this with LFO’s and a javascript queue.

    Hi tb

    I was working with Lissajous curves a little while back. The national broadcaster in Australia (ABC) has a simple Lissajous curve as it’s logo (I think it is one), often flattened to 2D logo. It’s like standing sine wave wrapped onto a cylindrical plan. I couldn’t quite get that happening but lots of more complex ones were easy enough. Simple is hard sometimes. Funny how these trends happen by osmosis 🙂
