I need a full-stack augmented reality solution that lets customers virtually try on our jewellery catalogue both on their phones and on an in-store large-screen display. The experience has to feel premium: crisp, photorealistic pieces that hold up whether the user is standing a metre away from a 55-inch kiosk or sitting at home on a mobile screen. Scope of work • Build native AR try-on for iOS (ARKit) and Android (ARCore) as well as a kiosk version that can run the same scene in Unity or Unreal on Windows. • Create the 3D models from my design files; every ring, pendant and earring must be modelled, textured and optimised for real-time rendering. • Allow users to rotate and zoom each piece, see it automatically aligned on their hand, neck or ear with live camera AR, and swap metals or stones to compare finishes. • Keep load times low without sacrificing visual fidelity—PBR materials, HDRI lighting and accurate scaling are mandatory. Deliverables 1. All 3D jewellery assets in FBX or glTF, ready for real-time use. 2. A single codebase (or clearly separated mobile and kiosk builds) with documented source, ready for submission to App Store, Google Play and kiosk installer. 3. Basic CMS or JSON structure so my team can add new SKUs, colours or price tags without rewriting code. 4. One walkthrough video plus user guide that shows installation, calibration and the try-on workflow. Acceptance criteria • Models match supplied CAD drawings within 0.2 mm on key dimensions. • Real-time render reaches 60 fps on an iPhone 12 and on a GTX-level kiosk PC. • Colour/material switch completes in under 500 ms. • Hand tracking and auto-alignment work in normal indoor lighting with no markers. If you already have a portfolio piece that proves similar AR try-on quality, link it; seeing live metal reflections and gemstone dispersion in motion will be the fastest way to move this forward.
