[vtkusers] problems with ICP alignement

[Jonathan.Bailleul]

Dear all,

I'm using ICP to align polydata of very similar shape but various
positions and orientation. In general, this works fine for the shape I
study, but here is a case where ICP fails!

Please note that in the general case, I might also be obliged to adjust
the scale factor of the mesh to align in order to converge to a relevant
result: in that one, no adjustment managed to make it.


How could I do to have it work in all cases? Adjusting the initial
orientation of the shapes (how?)?

In advance, thanks a lot for your comments
