[vtkusers] Masked rendering with stencil?

[Giancarlo Amati]

Hello Vtks :)

this is my question: I would like to make a rendering window where I have a kind of Mask (see mask.jpg in attachment) which simulates the view through a tube/cannula/pipe. In the white are there will be the standard rendering, but how can I superimpose that mask?

many thanks.
GC.
