tagging @ebruneton cause his forest publication was linked in this. @ebruneton do you have source code available for the forest demo similar to the clear sky and atmospheric scattering demos?

ebruneton commented 5 years ago

The Proland repository contains a demo with source code, but it is not a standalone demo as for the sky.
