Lol can we forget the whole thing and make this thread go away?
There must be an issue with my rotation.
When I reproduce the second animation, as the iterations get near 200 or so,
the sawtooth becomes as good resolution as infinite is going to get on a limited resolution screen.
I can explain and fix the jittery points (it’s because I’m only connecting every third sample).
When I reproduce the first one it’s great except there’s a little kink in the middle of the diagonal part of the wave.
That is not uploaded though... I’ll look into it again :O
