[vtkusers] Problem getting correct results with vtkProjectedTerrainPath

[Amy Squillacote]

Hi Elvis,

You could try using a vtkProbeFilter: 
http://www.vtk.org/doc/nightly/html/classvtkProbeFilter.html. Create an 
empty vtkImageData (sized and positioned to encompass the output of your 
vtkWarpScalar filter), and pass it as the "source" (2nd input) to 
vtkProbeFilter.
