[vtk-developers] progressive rendering

[David E DeMarle]

vtkRenderer::EraseOff() and vtkRenderWindow::EraseOff() is what you
are looking for.
They let you render a frame, make some change to the pipeline, and
render again and have the result of both renders composited together.

cheers,
Dave DeMarle
