Detailed Description

Allocate the positions uniformely (with constant density) randomly within a disc.


UniformDiscPositionAllocator allocates the positions randomly within a disc $ D $ lying on the plane $ z=0 $ and having center at coordinates $ (x,y,0) $ and radius $ \rho $. The random positions are chosen such that, for any subset $ S \subset D $, the expected value of the fraction of points which fall into $ S \subset D $ corresponds to $ \frac{|S|}{|D|} $, i.e., to the ratio of the area of the subset to the area of the whole disc.

Note
using UniformDiscPositionAllocator is not equivalent to using a RandomDiscPositionAllocator with a uniformly-distributed radius, since doing that would results in a point distribution which is more dense towards the center of the disc.
