I'm trying to work on a way to use geometry nodes to make different size spirals using arcs. I found that if you have multiple arcs with smaller and smaller sizes you create a form of spiral.
What I'd like to do is have a control easily from the "modifier tab" how many arcs i have. e.g. In this example i have 2 arcs (but i will want more).
I have it so that if it is "0" then i have 1 arc (the top arc) and i can control it's sweep angle.
Ideally, i'd like to have a value in the modifier tab that says how many arcs to add.If it was 2 arcs a) keep 1st arc at 180 b) add 2nd arc c) be able to control sweep angle of 2nd arc from modifier tab
then i'd like to say "3 arcs" a) keep 1st two arcs at 180 b) at 3rd arc c) control 3rd arc sweep angle from modifier tab
etc
Any ideas on how to do that simply. i can do it sort of easily manually by having lots of separate Group Input nodes but i really feel there should be some clever maths to do it.
Thanks Richard
