[Paraview-developers] Generate Ids filters and color schemes

[Cory Quammen]

Hi Kevin,

The GenerateID filter determines the array name. You can change it in
each object by changing the "Array Name" option in the GenerateID
filter properties. With different names, you should be able to set
different color maps on your line objects.
