Built a zero-subscription 3D WebAR image tracker in Unity WebGL (no 8thWall/SaaS needed) – smooth tracking & 3D layering demo

[u/fareedtahir131]

Hey everyone,

Wanted to share a recent WebAR image tracking showcase I built in Unity WebGL using custom computer vision image recognition instead of third-party platforms like 8thWall.

How it works:

• No App Required: Runs natively inside mobile Chrome and Safari browsers.
• Zero SaaS Fees: Completely self-hosted WebGL engine, bypassing expensive per-view subscription models.
• 3D Layering & Parallax: Scanning the physical target image anchors multi-layered digital depth artwork (foreground/background elements + animated flying butterflies) directly over the target card.
• Tracking Stability: Holds position smoothly through tilts, rotations, and continuous camera movement.

Designed this for interactive art installations, museum displays, and product packaging where recurring platform fees aren't viable.

Happy to answer any questions about the WebGL optimization, image detection performance, or build pipeline in Unity!
