Detailed Description

An EmitterVolume that emits particles from the interior of a circle.

The points are distributed uniformly in the volume using this function:

    Given the radius r and the random values t:[0,1) and u:[0,1),
    
        x = t * r * cos( u * TWO_PI )
        y = t * r * sin( u * TWO_PI )
        z = 0
