[vtkusers] timeseries data

[WolfgangZ]

Hi I want to update some the coloring of my unstructured mesh to display 
timeseries data. The problem now is that the iren = 
vtk.vtkRenderWindowInteractor() displays the image until the user 
terminates the window. Removing the Interactor the images just pops up 
very short ( renderWindow.Render() ).

What do I need to do to display the render window permanently but still 
beeing able to run a loop in python to check for new data and update my 
coloring scheme?

Many thanks for any help
