[vtkusers] Problem getting correct results with vtkProjectedTerrainPath

[Elvis Dowson]

Hi Bill,
                Would you be able to spare me a few minutes and tell  
me how to sample the output of a vtkWrapScalar, so that I can feed it  
to vtkProjectedTerrainPath?

I'm stuck with this problem for over a week now, and I tried  
suggestions from all the people who have responded, but I still  
haven't made any headway.

I think I'm missing something fundamental here and was wondering if  
you could take a look at the script that I've developed so far and  
tell me what I'm doing wrong.

I'm trying to sample the output of vtkWrapScalar into vtkImageData  
using vtkProbeFilter. This is to create a vtkImageData with the new  
scalar height field values that can be sent to vtkProjectedTerrainPath.

At the moment, the application hangs at vtkProbeFilter.

Best regards,

Elvis Dowson
