[vtk-developers] Active scalars and the behavior of vtkAppendFilter

[Cory Quammen]

Consider Backwards Compatibility?

Yes, there is that to consider. The most backwards compatible-friendly
ways to make any changes would be to either

1) add a flag that determines whether to merge by active attribute
(current behavior) or merge by name only, defaulting to the first
option to retain the current behavior, or

2) create a separate filter that merges only by name.

Option 2 seems too bloaty to me. Option 1 keeps the element of
surprising behavior by default, but maintains backwards compatibility,
and appropriate documentation of the merging options should hopefully
make it easy for someone to choose the behavior they might have been
expecting.

Option 1 sounds the best to me.
