Filament is a great lightweight cross-platform PBR rendering library. There's a few things missing (real GPU instancing is one), but in terms of shadows/antialiasing/color grading, it's very powerful. The material (shader) language is also very accessible. I maintain an open-source Dart/Flutter package[0] which is mostly a wrapper around Filament. This makes it considerably easier to have a single UI+codebase that runs across macOS, iOS, Android, Windows, and Web. [0] https://github.com/nmfisher/thermion https://github.com/nmfisher/thermion
