[vtkusers] Vector output of a vtkPropCollection of vtkPolyData

[Louis le Grange]

I am looking for a vector writer similar to the CGMWriter.

I need however to be able to get the data of not only one vtkPolyData object
as in vtkCGMWriter but to get the data of all the props in a
vtkPropCollection data made up of many vtkPolyData objects. Do anyone have
any ideas or know of such an example?

Thanke
