Function circleRings

Generates points spaced out on the given number of rings.

Get points as array

const circle = { radius: 5, x: 100, y: 100 };
const opts = { rings: 5 };
const points = [...circleRings(circle, rings)];
Copy

Or iterate over them

for (const point of circleRings(circle, opts)) {
}
Copy
