Curved Tracker Features

Drag and drop 3D models, videos, and interactive content onto cups, cans, bottles, and other curved surfaces to create WebAR experiences in Unity—no coding required.

Track and anchor content onto cylindrical and conical objects such as cans, bottles, and curved packaging.

Enable tracking across multiple curved targets within a single experience, allowing for richer and more dynamic AR interactions.

Convert between rectangular and conical (polar) image formats with ease. Generate conical cutout patterns for curved surface testing, or undistort polar images back into standard rectangular formats to simplify preparation and refinement of curved tracking assets before deployment.

Works across Chrome, Safari, Edge, Firefox, and in-app browsers like WeChat, Facebook Messenger, and Viber. Easily embed your WebAR into mobile apps via WebView.

Ready-to-use examples to help you get started with AR in minutes.

Supports Unity 2022 LTS and Unity 6, providing long-term stability and compatibility with upcoming versions.

Create WebAR Experiences on Cylindrical and Conical Surfaces. Attach interactive AR content to cups, cans, bottles, and other curved objects with fast, accurate browser-based tracking.

Important

This Curved Tracker plugin is currently not interoperable with our other trackers. Support for combining multiple AR trackers in the same experience is planned for future updates.

Combining multiple trackers is possible experimentally. This prototype demonstrates using Image Tracker together with World Tracker to create extended tracking experiences.

Watch the Image Tracker + WorldTracker Extended Tracking experiment

Watch the Curved Tracker + WorldTracker Extended Tracking demo

In-editor testing is currently not supported. To run the full experience, build your project for WebGL, or use our editor debugging tools for development and testing.

Why WebAR?

WebAR is best suited for lightweight, accessible, and shareable AR experiences.

Users can launch your experience instantly by opening a link or scanning a QR code. No app download required.

No Hosting Fees

Unlike many WebAR platforms that require monthly subscriptions, per-view fees, or per-app-id pricing, you can host your own experiences and avoid recurring platform costs.

White-label

Host your WebAR experiences like any other Unity WebGL build.
Upload to your own domain or website — the entire technology stack is yours.

No Markers Required

Uses natural feature tracking, allowing you to detect and track any image with sufficient visual detail.

Fast and Accurate Tracking

Built for high-quality image tracking in the browser. Performance is close to leading industry image-tracking solutions while running entirely through WebGL.

Curved Tracker Features

Track Cylindrical & Conical Surfaces

Detect and track curved image targets on cups, cans, bottles, and other cylindrical or conical objects.

See the cylindrical tracking demo (bottle)

See the conical tracking demo (tapered cup)

Multiple Target Tracking

Track multiple curved image targets simultaneously within a single experience.

Curved Mesh Generator

Automatically generate cylindrical and conical meshes that match your curved image targets.

Depth Mask Shader

Create realistic occlusion by hiding virtual content behind curved objects.

Conical Pattern Exporter (Experimental)

Generate printable conical cutout patterns from rectangular images for rapid testing. Watch the pattern generation tutorial.

Conical Image Undistorter (Experimental)

Convert conical (polar) images into rectangular textures for use as curved image targets. Watch the image undistortion tutorial.

Post Processing & HDR Support

Create richer WebAR visuals with support for Unity Post Processing and HDR rendering across both Universal Render Pipeline (URP) and Built-In Render Pipeline. See it in action in the Post Processing & HDR demo video.

Use Cases

Create WebAR experiences for:

Interactive cans, cups, and bottles
Product packaging AR
Marketing campaigns
Brand activations
Interactive product experiences

Summary

This plugin works similarly to other AR image tracking plugins, but is designed specifically for Unity WebGL.
Setting up your AR scene only takes a few minutes (Watch the Curved Tracker Demo tutorial).

Supports major desktop and mobile browsers including Chrome, Safari, Edge, and Firefox.
It has also been tested inside built-in browsers from messaging apps such as WeChat, Facebook Messenger, and Viber.
