Programmatic swirl function

Question

In the following post @joojaa writes out the math function for the artwork shown here:

His code is specifically in PostScript, which is awesome...but I'm wondering if this can't be converted to Javascript specifically to be written as an Illustrator script. I've tried it myself with no luck.

  var t = 1000;   //not sure what 't' should be other than a number
  var e = a.pathItems.ellipse(20*Math.cos(t)-10*Math.sin(5*t+Math.PI/2), 20*Math.sin(t)+10*Math.cos(5*t+Math.PI/2));
  e.stroked = true;
  e.filled = false;

The code actually does generate an ellipse but its def not correct.

Any ideas on how to draw a math function for Illustrator using scripting?

Answer 1

I assume that this question is addressed at me. No, it isn't PostScript, its just a function I didn't claim otherwise (i mean pots script as in 'appended'). See GD.SE does not support LaTex so I use the next best thing, code.

You can drop the function into any function graphing utility you have. But if you dont have anything useful you can find one that I made for Illustrator users here (it is called jooGraphFunction), documentation can be found here with examples. Unfortunately there are infinite number of functions so I cannot cover entire math spectrum. But just as a tip Wikipedia contains quite a lot of examples.

Dont worry everything can be misunderstood. :)
