[vtkusers] vtkWarpScalar->SetInput(vtkPolyData *). Should it work?

[Amy Henderson]

Hi Nico,

Did you do a #include "vtkPolyData.h" in the file that contains this piece 
of code you described in this e-mail?  It looks like the compiler doesn't 
know that vtkPolyData is a subclass of vtkPointSet, and if that's the case, 
adding that #include should fix the problem.
