I'm not sure exactly whether you mean particle visualization in vector
fields that change over time or animated particle releases in a static
vector field. If you mean the latter; I have played with vtkStreamLine to
create animated particle releases.

Attached you will find a Vtk/Tcl script and an example data set that
illustrate the idea. I have stripped it of all decorative code in the
hope that it's simple enough to understand. The basic idea is to use the
data generated by vtkStreamLine to animate a sphere-shaped particle over
the positions of the streamline.

Good luck,
