I’m trying to use vtk on pyqt5. I just need to display the model in the background of my window. The background rendered by Renerer is too ugly. Can I make the background of Renerer transparent?

Stack Overflow had a [similar question](https://stackoverflow.com/questions/34789933/vtk-setting-transparent-renderer-background).
The VTK link they point to is broken, but was probably meant to be [this page](https://kitware.github.io/vtk-examples/site/Cxx/Utilities/Screenshot/)?
