[vtkusers] Problem using vtkIterativeClosestPointTransform

[Jean-Baptiste Vimort]

Hi everyone,

I'm working on a module for Slicer, and I have some difficulties with
vtkIterativeClosestPointTransform:
When I run my code I haven't got any errors but in some cases, that I can't
really identify, my output transform matrix is only filled with "nan".

I was wondering if someone know how work the algorithm of this transform?
And if it exist some conditions needed on the inputs polydata to avoid
those "nan" in the output transform matrix?

Any help will be greatly appreciated!

Thank you in advance,

Jean-Baptiste
