What's the best way in Sverchok to create a circular sinusoid, like I drew here with the grease pencil?
I can imagine one one:
1) displace the circle vertices along their normal; or 2) generate a sin curve and wrap it around an origin point
Or maybe there is a third way? Is one of these methods preferable, or more generically useful, from a Sverchok perspective? What would the node setup be?
