## What it is
XR Animator is an AI-based full-body motion capture application that uses a single webcam with MediaPipe and TensorFlow.js to drive MMD/VRM 3D avatars in real time. It runs as a web app in browsers and as an Electron desktop app, supporting VTubing, XR scenes, and motion export to VMD/BVH/glTF formats.

## Use cases
- animate a VRM avatar with webcam face and body tracking for VTubing
- capture full-body mocap from a webcam and export to BVH or VMD
- stream VMC-protocol motion data to VSeeFace or Warudo
- turn 2D images into 3D backdrops with AI depth maps
- track real-world objects with a webcam and map them to 3D props
- run a 3D wallpaper gadget on the Windows desktop

## When to choose
- you want markerless webcam mocap without special hardware
- you need a browser-based VTubing solution that also works on smartphones
- you want to animate MMD/VRM models with ARKit-compatible blendshapes
- you need motion export in VMD/BVH/glTF formats

## When to avoid
- you need studio-grade mocap with suits or depth cameras
- you require a native SDK to embed mocap into your own engine
- you need guaranteed licensing clarity - the repo has no license file
