the path I was talking about has nothing to do with the trajectory (well not by
itself) it is a spline which determines the path of the target point as the
emitter moves (also based on a spline).

so the spline resembles a sine wave with a high frequency, hence the emitter
travels up and down as it sprays particles, and the target point moves
similarly.
