Filament is Google's real-time physically based rendering (PBR) engine written in C++, designed to be small and efficient, especially on Android. It supports OpenGL ES, Vulkan, Metal, and WebGL2/WASM backends and includes a glTF 2.0 loader and material compiler tooling.

Use cases

• render 3D models with physically based shading in a mobile app
• display glTF 2.0 assets in an Android or iOS application
• build a real-time 3D viewer that runs in the browser via WebGL2
• integrate a lightweight PBR renderer into a cross-platform C++ project
• render 3D product visualizations on mobile with high performance
• compile custom PBR materials with a material compiler toolchain

When to choose

• you need high-quality real-time PBR rendering on Android with a small footprint
• you want one rendering engine across mobile, desktop, and web (WASM)
• you need glTF 2.0 asset loading with a mature material system
• you prefer a C++ library with Java/Kotlin bindings via Maven

When to avoid

• you need a full game engine with physics, audio, and scene management built in
• you want an easy high-level engine like Unity or Unreal rather than a rendering library
• your target platform lacks Vulkan, Metal, OpenGL ES, or WebGL2 support
• you need ray tracing or offline rendering rather than real-time rasterization
