Guys,
After some weeks of silence, I'm back with a question... addressed to the trig-savvy users, mind you...
I'm working with some patterns and I need to create a 2D wavy circle. I'd like to do it on my own, through a graphing calculator. It seems that, as of recently, drawings of even the most basic geometry figures are subject to copyright and royalties. ::)
Unfortunately, it seems I lack the knowledge regarding how such object can be described through equation.
Do you have any idea how it could be achieved? Please keep in mind - I do not mean how to do it in Terragen. All I ask for, is the mathematical formula (this is why this topic is filed under "Open Discussion").
I'm not sure whose charging for math formulas but there are plenty of resources to start from online. First result here: https://www.allmathtricks.com/circle-formulas-area-circumference/#Circle_Formulas_in_Math
This looks fun:

But I guess you already found that site.
Here is a way to do it in programming:

It`s not a formula you can use but maybe it helps to figure out one by yourself.
My search after "formula for a circle with wavy edge" brought up a lot more promising looking results.
CHeers, Klaus
js and canvas is actually really fun to play with. Some good online IDEs too.
