How to Create Image-Tracked WebAR Experiences in Unity | ZapWorks Unity AR SDK

Get started with ZapWorks Universal AR here: rb.gy/6thcc4
Learn how to create Image-Tracked experiences in Unity with our Unity AR SDK.
** Please note, the "Zappar Image Tracker" has now been renamed to "Image Tracking Target" in the Zappar menu.
This video will show you how to get going once you’ve downloaded the Zappar package, including:
- How to add a Zappar Camera and an Image Tracker Target as a GameObject
- How to use the image trainer to turn a standard image into a target image
- Using image parameters
ZapWorks Universal AR SDKs help you build AR easily in the languages and platforms you know best. Building augmented reality using Unity has never been easier - download a Unity AR example project to get started with making image-tracked WebAR.

Just followed your tutorials to get this working over WebGL, thank you for those! I'm testing with a self-hosted site and it works pretty good. An issue I am having is when the image is no longer seen by the camera, the image with the instantiated object sticks to the screen and follows my device and sometimes will freeze camera feed. Is there a way to keep the instantiated object in memory so it can remember its location within the environment (similar to what happens when using in HTML) instead of following my device?

Hi there - we’re so glad you’re enjoying the Universal AR SDK for Unity! It might be helpful to know that you can remove the overlaying preview image in your experience through the image target trainer: docs.zap.works/universal-ar/unity/tracking/image-tracking/#zappar-image-trainer Mixing environment tracking with image tracking would class as extended tracking, and would therefore require quite a lot of mathematics! It’s for this reason that we find developers tend to hide content when the target image is not in view, using the target image’s 'On Seen' and 'On Not Seen’ events. Or, if you don’t need a target image, you could try instant world tracking, which is our environment tracking solution built for the web. You can learn more about our tracking types and the Universal AR SDK for Unity on our documentation site here: docs.zap.works/universal-ar/unity/getting-started/ - Francesca

@@ZapparApp Thank you for your response! Yes, I found I can remove the image, so that's cool, thanks! Thank you for the suggestion, I was able to setup an instant world tracking project and have it hosted. I can tap to place the object, which is great, but it doesn't entirely stay put. The object will be placed where I tapped, but if I walk around, the object follows a bit and is a little jittery. Is this common? If it matters, I'm using Safari on an iPhone 13 Pro on iOS 16.4.1.

@@drumdover Hello, it’s great to hear how you’ve been getting on! Generally, we recommend looking at or placing instant world tracked content on a textured surface; this is so that anchor has something to ‘grab on’ to. It can also be helpful to position content anchor-first, rather than content-first. This means that content should be as close to the center of the tracker as possible; and if you need to adjust content positioning, you should start by manipulating the Instant Tracker’s AnchorOffsetFromCamera parameters first, rather than positioning specific content (e.g. a mesh). Moving content too far away from the tracker in either direction will naturally cause what appears to be 'drift', due to the perspective and our natural eye. Please do look forward to updates coming to our environment tracking solutions. If you are particularly struggling, please do feel free to send an email in to [e-mail] and we'll be happy to assist! - Francesca

I have a canvas object and a 3d model inside the Zapper Image Tracking Target. Before the camera detects the target image, my canvas and 3d objects gets shown.

[@ZapparApp]

Hi abhishekfredrick, please check your email, we have responded to your ticket on this matter. Thanks!

[@jabrailchumakov]

I did the same way. But now my GameObject appears in the camera view always. I see part of the cube all the time, and in case I show an image target it spawns one more object. How to fix it?

[@ZapparApp]

Hi there, to resolve this issue can you check that the GameObject is placed correctly in your Unity scene. It should be positioned at the center of the image target or the tracking area where you want it to appear. Also, make sure it's not below the image target in the scene. Additionally, check your hierarchy to make sure that the GameObject is within the image tracker group. hope this helps and for further support, please submit a ticket at docs.zap.works/contact/

[@anoushkagoel3068]

When i host, the image target and the augmented GameObject tends to stay stuck in one place when i host it. Please help me out with this!!

[@ZapparApp]

Hi there! It might be that your onVisible or onNotVisible behaviour is not set up - we have some great documentation here: docs.zap.works/universal-ar/unity/ , or you can join our community Discord at discord.gg/D8F5YpnukH :) - Francesca
