Live Demo

• Clone or fork the repository
• Install dependencies: npm install
• Start HTTPS server using precompiled code: npm start
• Navigate to https://localhost:8001

• Clone or fork the repository
• Compile code on-demand & start HTTPS server: npm run dev
• Navigate to https://localhost:8001

• All heavy-lifting (machine learning processing) is performed using Human library
• Enabled models are: BlazeFace-Back, FaceMesh-with-Attention, BlazePose-Heavy, HandTrack, HandDetect
• 2D visualization is performed using built-in draw methods in Human library
• 3D visualization is performed using BabylonJS

Process flow is separated into two loops:

• Process loop
  Runs in web-worker so its not blocking the main thread
  Supports WASM, WebGL and WebGPU backends
  Runs as fast as possible: frame is submited to worker and as soon as results are available a new frame is submitted
• Render loop
  Runs at fixed 60 FPS
  Draws both 2D canvas overlay and 3D GL mesh
  Uses intepolated (for smoother output) results based on last known processed results from process loop
