the minimum radius away from origin. should be between 0 and maxRadius (both inclusive).
[outerSpacing]
if defined, the distance between points will be Lerped from to [outerSpacing], to create a gradual distribution from minRadius to maxRadius.
[distributionBias]
(vec2) if defined, the density of the points will be changed gradually along the direction of this vector. the magnitude will be use as scalar, with 1 being the norm scale.
