Ok thanks for the help so far, but ive been looking through the doc and the
error messages im getting from tcl, it seems that
SetInputConnection/GetOutputPort from vtkAlgorithm returns a vtkAlgorithmOutput
while GetOutput/SetOutput deals with vtkDataSet (in the vtkIterativeClosestPoint
algorithm that im trying to use. Any idea on how to get from the
vtkAlgorithmOutput that my transformation code outputs to a vtkDataSet that my
ICP needs?

Thanks
