## What it is
A React Native library providing a real-time physically based 3D rendering engine built on Google's Filament, with native C++ rendering and Bullet3 physics. It exposes a declarative React component API and renders GPU-accelerated via Metal on iOS and OpenGL/Vulkan on Android.

## Use cases
- render 3D models in a react native app
- load and display glb/gltf models on mobile
- add 3D physics simulation to a react native app
- gpu-accelerated 3d rendering on ios and android
- build interactive 3d product viewers in react native
- replace expo-gl with metal-based rendering

## When to avoid
- you are building a web-only or non-React-Native project
- you need desktop 3D rendering
- you need formats other than glb/gltf
- you need a full game engine with editor tooling

## Facets
- artifact type: library
- maturity: active
- function: graphics, game-engine, animation, ui-components
- domain: mobile-development, graphics, cross-platform
- platform: cpp
- tags: react-native, 3d-rendering, physically-based-rendering, gltf, metal, vulkan, opengl, bullet3-physics, filament, gpu-accelerated, game-development, ios, android, mobile, gpu
