@codexo/exojs-particles / particles / stable

Random point on or inside a circle of radius `radius`, centred at `(centerX, centerY)`. With `mode: 'edge'` the result lies exactly on the circumference; with `mode: 'volume'` (default) it lies anywhere in the disk, with uniform area density (sqrt-of-random-radius distribution). Use as a spawn-position distribution for circular emitters.
