[vtkusers] Making camera follow a path defined by a set of points

[s comp]

How could I make the camera follow a path defined by a set of points? Also I would like to define the camera direction by this set of points.
 
 
Specifically I am thinking of making the camera follow a streamline of  a vector field.
 
I guess this a matter of just "doing the work", but I suppose someone might have done something like this before, and could offer some suggestions or advice.
 
Thanks,
 
Sonam
