[vtkusers] Please, how to get vtkPolydata with a texture applied from vtkActor?

[alican]

I have an actor that is set with polydata clipped from another polydata. 
Afterward I am adding a texture to this actor. All works as expected.

Now, in another place of my program I want to get a polydata, including
texture, from this actor
and append it to another polydata using vtkAppendPolyData filter. How can I
do this? 
If I am using actor->getMapper()-> getInput() there is no texture.
Thanks.
