Field notes
The homepage frames the project as a successor—not a port—to osgHimmel, a C++ renderer associated with Limberger’s 2012 master’s thesis and a related paper. It describes scattering lookup tables that can be tuned and recomputed, and environment maps that update as the Sun moves; cloud rendering and several named modules are marked planned. The page links MIT and CC BY 4.0 license texts, though the extract does not specify which material each covers.
