jReality is a Java based, open-source, full-featured 3D scene graph package designed for 3D visualization and specialized in mathematical visualization. It would be really good to have an ebuild for it. I failed doing it myself as I am not very experienced how to resolve dependencies. These days many java projects tend to just ship precompilded jars of their deps. Most notably jreality depends on jogl ( bug #143019 ) Having an ebuild for jreality would probably allow to revive visualization in sci-mathematics/polymake Reproducible: Always
