Hi,
when i am running this code, this example(
http://vtk.org/gitweb?p=VTK.git;a=blob_plain;f=Examples/DataManipulation/Cxx/Arrays.cxx
) *showing an error : 'SetInputData'* : is not a member of
'vtkPolyDataMapper', but when i am checking this class, this class has this
member function, could you please tell me, why i am getting this example?
Looking forward your reply.
