[vtkusers] Hide backface Silhouettes returned by vtkPolyDataSilhouette

[Geeta]

Hi


I have used "vtkPolyDataSilhouette" for Polydata and this returns the
Silhouettes of whole polydata .

I want to show only for the front side and hide / remove Silhouettes of the
backfaces.

Can anyone help?

<http://vtk.1045678.n5.nabble.com/file/n5742041/Polydata_Transparent_1.jpg> 

Even if the poly data is Transparent I want to show the Silhouettes which
are shown when poly data is opaque. no Silhouettes from back faces.
