[Insight-users] vtk polydata import / export

[imho]

Hi Luis,

I use vtkPolyData to represent 2 3D liver's models builded from slices.
I already do registration on it with VTK (point-based + ICP), and now 
I'd like to use the demon registration in ITK.
So I'll try the conversion you purpose.

Thanks for your help

Imho.
