For StructuredGridData, I use something like this (in TCL)

vtkPolyDataMapper gridmapperz
    gridmapperz SetInput [planez GetOutput]
    gridmapperz ScalarVisibilityOff

vtkActor gridActorz 
    gridActorz SetMapper gridmapperz
    [gridActorz GetProperty] SetRepresentationToWireframe
    [gridActorz GetProperty] SetColor 0.1 0.9 0.1
    [gridActorz GetProperty] SetAmbient 1.0

where the planez is the output of vtkStructuredGridGeometryFilter
working on the data set.
