TraceARJitter-free image tracking for the mobile web

A Rust → WASM AR engine with sub-pixel tracking and a self-calibrating camera — ~95 KB gzipped, free and MIT-licensed.

🎯

Sub-pixel tracking

After detection, an inverse-compositional patch tracker locks on with sub-pixel precision — 1.90 px median jitter measured on a real phone.

⚡

Rust compiled to WASM with SIMD, running in a worker. The main thread only pumps frames and renders.

📷

Full 6DoF pose with online focal-length estimation. Your users never see a calibration step.

🧊

An adapter drives a correctly-projected camera and per-target anchor groups. Drop your content in and render.

📦

WASM binary included. Two tiny image codecs are the only dependencies; three.js is an optional peer.

🆓

MIT-licensed, no keys, no accounts, no usage limits. Compile markers locally with one CLI command.
