[Paraview] Filters

[Renteria, Jose (Cont, ARL/CISD)]

I am trying to create a new Paraview Filter that is a combination of
two filters, a cut (vtkCutter) and pick filter (vtkPickFilter).  My
goal is a cutplane filter that creates a cutplane by selecting
(picking) three points.  

I can create each filter independently, however joining them has been a
problem.  Say I create a cutplane filter, how do I get the inputs from
the cutplane filter to initialize the pick filter or vise versa? 

Thanks,

Jose
