[Paraview-developers] Replacement of SetInput with SetInputData (VTK5 vs. 6)

[Utkarsh Ayachit]

> Thank you for helping me understand better how the VTK pipeline works. Just to be sure: even though the data object is modified (directly, not through an algorithm object) after the call to cp->Update(), I can safely pass it on further (in this case to the output data object) without having to call Update() again on its producer?

Yes. In fact, if you modify the data object directly after
cp->Update(), then calling cp->Update() again may result in the data
object being overwritten if the "cp" reexecutes.
