SphereEmitterShape class Particles
Emits particles from a sphere (or its surface, or a hemisphere), each headed radially outward.
With surfaceOnly false (the default) positions fill the volume uniformly (a cube-root correction keeps the density even); with it true they land on the shell. hemisphere restricts both position and direction to the +Y half. A zero radius degenerates to a point emitting in uniformly random directions.
