Is there a way to randomize the location of points within a PointSource over time for ParticleTracer


I am trying to visualize a time-dependent flow with the ParticleTracer filter and am using a PointSource as my source while injecting particles at every time-step to get a pathline/streakline effect. I am having decent success; however, the fact that particles are seeded at the exact same locations for every time-step makes it look a little unrealistic. If I could simply displace the point-source locations by some random, small amount each time I inject particles, I imagine I could get a very realistic smoke effect.

I’m sure there is a way to do this, but I haven’t been able to figure it out. I would greatly appreciate any suggestions that any of you might have to accomplish this.

Thanks a lot.
