[vtkusers] Old-style pipeline connection, new style, and vtkStructuredGrid

[Carlos Rafael Giani]

Hi,

from what I hear, it is discouraged to use old-style pipeline connection 
(e.g. SetInput() and GetOutput() etc.)

However, I have a structured grid, and vtkStructuredGrid works well for 
me. I have to use SetInput() to connect the grid to a vtkContourFilter, 
for example. I've searched for some vtkAlgorithm derivative that offers 
me the same functionality as vtkStructuredGrid, but so far nothing worked.

Or is there some sort of wrapper for data objects like vtkStructuredGrid?
