Circle with concentric subdivisions?

[marquizzo]

I know three.js has CircleGeometry, which allows for custom segmentation along the circumference of the circle, creating pie-slices. But is there a way to also create concentric subdivisions (in red)?

I’ve seen the source code only allows for the center point to fan out to the outer edge. Does anybody know of an algorithm that could also create these concentric subdivisions?

I found it after a deep scrolling through the documentation. I guess RingGeometry is something that exists!
