## What it is
Rajawali is a 3D rendering engine for Android built on OpenGL ES 2.0/3.0 and written in Java. It provides a scene graph, cameras, materials and shaders, model loaders (FBX, MD5, AWD), animation, post-processing effects, and support for regular apps, live wallpapers, VR, and Wear.

## Use cases
- render 3D graphics inside a native Android app
- create an animated 3D live wallpaper on Android
- load and display 3D models like FBX or MD5 on Android
- write custom GLSL shaders and materials for Android scenes
- add post-processing effects to Android OpenGL scenes
- build a simple VR/cardboard viewer on Android

## When to choose
- You need 3D rendering in an Android app or live wallpaper without writing NDK/C++ code
- You want a pure-Java OpenGL ES engine with scene graph, materials, and model loaders out of the box
- Your project targets Android only and can work with OpenGL ES 2.0/3.0 capabilities

## When to avoid
- You're building a full game that needs physics, audio, and complete tooling — a full game engine like Unity or libGDX fits better
- You need a rapidly evolving feature set — the 1.x line receives minimal fixes while 2.0 is a long-running rewrite
- You target platforms other than Android — Rajawali is Android-specific
