[vtkusers] Advecting a mesh

[Moreland, Kenneth]

I have one mesh containing a vector field and another mesh that is an unstructured grid that I need to advect in the vector field.  That is, I want to trace where the points in the unstructured grid go in the vector field after some time T.

This advection is the same operation done by the stream tracer filter, except that I don't want to trace a line behind the points.  I just want to know where the points end up after the time I specify, and I can't have any points "die"if they leave the vector field or stop.  Is there a filter that advects points like this?
