Interactive 3D demo

Real-time visualization of a mobile tag inside a 3-anchor zone (simulated data).

This demo shows a tag moving inside a UWB-anchored zone. Distances are simulated (recording file), but the trilateration and Three.js 3D rendering code is identical to the production system.

How it works in real life

  1. The 3 anchors are placed at the corners of the zone to cover.
  2. The mobile tag measures DS-TWR to each anchor every 100 ms.
  3. The tag sends the 3 distances over WiFi/UDP to the PC.
  4. A small Node.js relay forwards the data via SSE to the browser.
  5. The browser runs trilateration and 3D rendering.
