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

[Nico Vermaas]

Hi Amy,

Thanks for your reply.
That seems to work better, but I still get this error

"inspect3d.cxx:1142: type `vtkPolyData' is not a base type for type `vtkPointSet'"

I tried to include "vtkPointSet.h", but that doesn't help. Any more idea's?

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.
