[Paraview] Design of Multiple Input Filter

[Michael Jackson]

I have an algorithm that needs to take 3 inputs. All three will be  
vtkImageData objects using Floating point values. I was wondering,  
before I even start anything, does the first data set in the pipeline  
have to be a composite data set so if I apply the filter I can assign  
specific "pieces" of the composite data set as inputs to the filter I  
am designing? What would be an example of a filter that takes multiple  
inputs that I could look at as an example?

Thanks for any help.
