Filament is a real-time physically based rendering engine for Android, iOS, Windows, Linux, macOS, and WebGL2.
Filament addresses the need for efficient, lightweight rendering on mobile platforms while maintaining visual quality through physically based rendering techniques. The engine is optimized for minimal size and performance on Android, supporting multiple graphics APIs including OpenGL ES, Vulkan, Metal, and WebGL2. It includes a material system with a dedicated compiler (matc) that generates optimized shaders, and provides a glTF 2.0 loader for asset import. The tool is distributed as precompiled binaries through Maven Central for Android and CocoaPods for iOS, with source builds available for other platforms.
Filament suits developers building 3D graphics applications on mobile platforms where resource constraints matter, or cross-platform projects targeting both mobile and desktop. The engine is particularly valuable for teams that need physically based rendering without the overhead of larger graphics frameworks. Android developers benefit from Maven dependency integration and modular libraries covering rendering, asset loading, and utilities. The project provides comprehensive documentation on PBR theory and its material system, making it accessible to graphics programmers learning physically based rendering concepts.
The project maintains active development with regular releases that bundle host-side tools required for asset generation. Documentation is thorough and kept current, covering both theoretical foundations and practical implementation details. The codebase receives ongoing optimization work, particularly around shader compilation and cross-platform graphics API support.
