I like John's suggestion, being able to pass collections in and out of
filters will be useful for other classes that work on sets of data. I have
two in mind (I presume John already has more):
vtkProcrustesAlignmentFilter - aligns sets of point sets mutually together
input: vtkPointSets
output: vtkPointSets
DenseSurfaceModelFilter - builds statistical models of surfaces
input: vtkPolyDatas
outputs: various
and I know Rasmus has in mind:
PrincipalComponentsFilter - finds 'modes' of shape variation
input: vtkPointSets (output of a vtkProcrustesAlignmentFilter)
outputs: various
If this is all wrong and the approach doesn't fit with VTK then please let
me know. The drawback with David's suggestion of GetOutput(i) & SetInput(i)
is that it makes pipelining filters a pain. Am I right?
Thanks,
Tim.
