The Vortex warp appears as a curved-arrow icon in the plane you drag
in, with a second, perpendicular arrow indicating the axis of rotation as
well as the direction of the well. This second axis is called the drop axis.
NOTE The position of the space warp plays an important role in the results.
The vertical position affects the shape of the vortex, and the horizontal
position determines its location. If you want the particles to spiral around the
particle emitter, place both at the same location.
