How does the simple.py module render polydata?

I want to use simple.py module on the server side to render polydata written by VTK, is there any way to solve this problem?
I’m not sure the method I’m looking for really works:

    trivialProducer = simple.TrivialProducer()
    trivialProducer.GetClientSideObject().SetOutput(polyData)
    simple.Show(trivialProducer)
    simple.Render()
