[vtkusers] How to compute streamline length?

[vincentrivola]

Dear all,I am looking for a simple (and as fast as possible) way to get the
curvilinear / arc length of a streamline generated using the vtkStreamTracer
filter.Is it it possible to get it directly as an output?So far I did an
ugly workaround but I would like to get something faster. My current code
uses vtkThreshold to select streamlines one by one and a sort filter in
order to compute the length of each segment of each streamline and then sum
them to get the curvilinear length of a streamline.
