Re: Finding a loop point in an Expression

I think you'd need to pick your 3 frequencies so that they are harmonically related to get any kind of reasonable loop time. Right now you have two true "frequency" values (where you have the Math.PI*2 multiplier in the wave calc) and one where you haven't done that, so I think the calculation for how often the waves all get back to their starting positions at the same time will be ugly.

Let's say you set it up where your frequencies are 1, .5, and 1/3 (for example). That gives you periods of 1 sec, 2 sec, and 3 sec. The lowest common denominator for that would be 6 sec, so your animation would loop every six seconds.
