## What it is
SysMocap is a cross-platform, video-driven real-time motion capture system that animates 3D virtual characters from webcam footage. It renders VRM and Mixamo FBX models with a Material Design GUI and supports OBS streaming, AR/VR via WebXR, and full-body tracking.

## Use cases
- become a vtuber with webcam motion capture
- animate a 3d character from video in real time
- stream an animated avatar with obs
- import vrm or mixamo fbx models and auto-map skeletons
- do full-body motion capture without sensors
- forward mocap data to ar/vr via webxr

## When to choose
- you want free, markerless webcam-based mocap for VTubing or live streaming
- you need VRM/FBX model support with automatic skeleton detection
- you want a polished GUI app on Windows or macOS

## When to avoid
- you need production-grade mocap for film or game pipelines with export to standard animation formats
- you require sensor-based or multi-camera precision tracking
- you need Linux binaries rather than building from source
