Detailed Description

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

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

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