[vtkusers] closest point on a surface / vtkIterativeClosestPointTransform

Dear VTKusers,

I'm using the "vtkIterativeClosestPointTransform" to register a point 
cloud to a surface. As far as I understand, this algorithm involves 
finding the closest point on a surface for each point in the point cloud.

I would like to know, if I can retrieve this information after the 
iteration converges, i.e. for each point in the point cloud, I would 
like to know the closest point on the surface?

Furthermore, I would like to compare the final mean point2surface 
distance with the initial one. Is there a way to compute the initial one?

I deeply appreciate any pointers!
