[vtkusers] Problem getting correct results with vtkProjectedTerrainPath

[Elvis Dowson]

Hi Mike,
                   Yes, that's exactly what I want to do. The I want  
to change the scale factor of the original DEM data, and then pass the  
new scaled height information to vtkProjectedTerrainPath.

Best regards,

Elvis
