[vtkusers] How to loop around vtkAppendPolydata ?

[tutu lamotte]

Dear List !

We need to find a way to "accumulate" many polydata
that are manually created (Without source object). The
huge accumulated polydata would be the output of a
vtkAppendPolydata instance. Now because it is an
accumulation, it means that the output would also need
to be the input of the same vtkAppendPolydata
instance. Each new polydata would be inserted as a
second input. (this second input would be disconnected
after Update is called on the Append filter. )
We've tried that approach but the end result is always
one single polydata... and not an accumulation of all
the datasets that were appended.

Hope it's clearly explained !

Thanks for any suggestions !
