PlayCanvasAR - Fast and Easy AR for the Web

PlayCanvasAR makes it easy to build lightning fast augmented reality applications. With it, you can construct web-based AR applications with zero programming using the PlayCanvas Editor. Just drag in your 3D models and watch them appear in AR!

But if you want to create something more interactive, you can call on the full power of the PlayCanvas scripting API.

Demo

Before you begin, print out the following markers: Hiro and Kanji.

Now click here for a demonstration. We recommend running it on mobile. If you use iOS, you'll need to ensure you have upgraded to iOS 11, which is required to access the camera from Safari.

Features

• Amazing Performance - PlayCanvasAR delivers 60 frames per second, even on mobile.
• Marker-based Tracking - PlayCanvasAR utilizes the amazing ARToolkit, an open source marker-based tracking library. Originally coded in C++, it has been ported to JavaScript using Emscripten.
• Incredible Visuals - PlayCanvas provides an advanced WebGL graphics engine. It supports the latest WebGL 2 graphics API and implements Physically Based Rendering to achieve incredible visuals for your AR applications. And yes, that's open sourced too.

Getting Started with PlayCanvasAR

1. Create an account on playcanvas.com (if you haven't already).
2. Fork the AR Starter Kit project (which contains the latest version of playcanvas-ar.js).
3. Hit the launch button and see AR in action (we recommend using your mobile device!).

Configuring PlayCanvasAR in the Editor

The playcanvas-ar.js script contains two script objects: arCamera and arMarker. The arCamera script renders a device's camera feed and tracks the feed image for AR markers. It can be added to an entity that has a camera component. The interface generated is as follows:

To create a new marker entity, simply add a script component and add the arMarker script. This will generate the following UI:

Scripting with PlayCanvasAR

The PlayCanvas Editor allows you to build your AR apps visually. But you may want to create AR powered entities programmatically. Or you may want to build AR apps by simply using the PlayCanvas Engine without the Editor. PlayCanvas AR exposes two script objects: 'arCamera' and 'arMarker'. 'Engine-only' scripting examples can be found in the examples folder.

arCamera

This code creates an AR-enabled camera:

var camera = new pc.Entity("AR Camera");
camera.addComponent("camera", {
    clearColor: new pc.Color(0, 0, 0, 0)
});
camera.addComponent("script");
camera.script.create("arCamera", {
    attributes: {
        cameraCalibration: asset,
        detectionMode: 0,     // Color Template
        matrixCodeType: 0,    // 3x3
        labelingMode: 1,      // Black Region
        processingMode: 0,    // Frame
        thresholdMode: 0,     // Manual
        threshold: 100,
        trackerResolution: 0, // Full
        trackAlternateFrames: false,
        debugOverlay: false,
        videoTexture: false
    }
});
app.root.addChild(camera);

arMarker

This code creates an AR marker entity:

var hiro = new pc.Entity("Hiro Marker");
hiro.addComponent("script");
hiro.script.create("arMarker", {
    attributes: {
        pattern: asset,
        matrixId: 0,
        width: 1,
        deactivationTime: 0.25,
        shadow: true,
        shadowStrength: 0.5
    }
});
app.root.addChild(hiro);
