How can i Copy an vtkActor ( vtkMapper ) ?

[Charles Law]

<x-flowed>Harald,

I do not know why you want to copy the data too.  Copying the actor and its
properties might be enough.  But ...

1: PointData and CellData do have methods called PassData.

2: In VTK3.0 you should be able to create a new vtkPolyData object (or 
vtkImageData...)
and set the last filter in the pipeline before the mapper with:

filter->Update();
oldData = filter->GetOutput();
newData = vtkPolyData::New();
filter->SetOutput(newData);
filter->Update();

Now oldData and newData should have exactly the same data.
