Hi
A forum-search on Lissajous should help get you started . . .
Also Peter Elsea has done some tutes on this matter . . .
Or there is always Scope~ in x/y mode . .
And one of the librarys has a Lissa object but I can’t remember . . Cheers

Check out the [jit.poke~] help file- play around with the settings of the 2 [cycle~] objects that control the 2 dimensions of [jit.poke~] in the patch.

you know how they are drawn?
then it should be easy

in jit.gl.sketch with a lot of lineto’s

here is some sourcecode + java app i found in google

That’s pretty cool.

Once you know the formula it’s just a matter of plugging in the values and deciding how fine you want the resolution, which in this case I imagine would be “how many points between 0 and 2*pi in your domain”. [uzi] and [scale] make this really easy, then you just have some parameters that you can change, going into an [expr]. Probably there are many other ways to do it too, but this way might demonstrate exactly what’s going on in the most straightforward way. It’s the brute-force method, plotting each point instead of using [cycle~] etc.

The resulting patch would be way better than the applet, too, since you could have any values you want for m and n, and change everything in so many more interesting ways than discrete changes to drop-down menus. Plus you could set the resolution and have all kinds of pretty colors. The resulting points would just go to a jit.gl.sketch, either with a lineto or a point command. Earlier versions of jitter will work fine for this I’m sure.
