Human: 3D Motion Visualization\n\n- Input  \n  **Video file**  \n  **Live webcam**  \n- Analyze and track all keypoints in a *web worker* thread  \n  Using [**Human**](https://github.com/vladmandic/human) library  \n  **Face**, **Body**, **Hands**\n- Display  \n  **Video Overlay** with keypoints  \n  **3D Mesh** with *pan/zoom/rotate* functionality\n\n\n\u003cbr\u003e\n\n![**Screenshot-Face**](assets/screenshot-face.jpg)\n![**Screenshot-Body**](assets/screenshot-body.jpg)\n![**Screenshot-Hand**](assets/screenshot-hand.jpg)\n\n\u003cbr\u003e\n\n## Run\n\n\u003cbr\u003e\n\n### Online\n\n\u003e [**Live Demo**](https://vladmandic.github.io/human-motion/src/index.html)\n\n### Offline\n\n- Clone or fork the repository\n- Install dependencies: `npm install`\n- Start HTTPS server using precompiled code: `npm start`\n- Navigate to \u003chttps://localhost:8001\u003e\n\n### Development Mode\n\n- Clone or fork the repository\n- Compile code on-demand \u0026 start HTTPS server: `npm run dev`\n- Navigate to \u003chttps://localhost:8001\u003e\n\n## Notes\n\n- All heavy-lifting (machine learning processing) is performed using [**Human**](https://github.com/vladmandic/human) library  \n- Enabled models are: **BlazeFace-Back, FaceMesh-with-Attention, BlazePose-Heavy, HandTrack, HandDetect**  \n- **2D** visualization is performed using built-in draw methods in `Human` library  \n- **3D** visualization is performed using [BabylonJS](https://www.babylonjs.com/)  \n\n## Processing\n\nProcess flow is separated into two loops:\n- **Process loop**  \n  Runs in web-worker so its not blocking the main thread  \n  Supports `WASM`, `WebGL` and `WebGPU` backends  \n  Runs as fast as possible: frame is submited to worker and as soon as results are available a new frame is submitted  \n- **Render loop**  \n  Runs at fixed 60 FPS  \n  Draws both **2D** canvas overlay and **3D** GL mesh  \n  Uses intepolated (for smoother output) results based on last known processed results from process loop
