Vuforia Fusion with ARCore

Hi there,

When Vuforia Fusion will have ARCore support

Thanks

 

Would like to know this aswel

 

ARCore will be included in the next major Vuforia update after version 7.1.

 

@Vuforia-Strasza And how do you use it exactly? I can find a good tutorial / document on this topic?

- Do i have to import the ARCore Unity Package first?
- Do i have to check the AR Code setting in XR Settings in Unity?
- Or is everything automatically done? So if AR Core is supported on the target device Vuforia Fusion will take it over?

Thank for any good tips or trics!

This article explains what you need to do in your project for Vuforia to utilize ARCore: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/arcore-with-vuforia.html

You will not need to check ARCore in the XR Settings, just follow the above instructions and use Vuforia as normal.

This article has some general information about how Fusion works and some info about APIs that help control and check it: https://library.vuforia.com/content/vuforia-library/en/articles/Training/vuforia-fusion-article.html

By default, once ARCore is present in your project Vuforia will utilize it for supported features. Using the APIs from the article above allows you some control over when and how ARCore is utilized.

 

Hi

This might be a stupid question but do you need the AR Core app installed on your phone in order to use Fusion? I have followed the steps and have been successful. However when I had the AR Core app installed, my app defaulted to using AR Core's camera implementation which does not focus the camera at all. Removing the AR core app allowed me to use the default Vuforia camera but does this also mean it won't use the Fusion features?

 

Hello @hyaqub_bmt,

Depending upon the device, ARCore must be installed on the device to use Vuforia Fusion. There are some devices that are *not* supported by ARCore but are supported by Vuforia VIO:

https://library.vuforia.com/articles/Solution/vuforia-fusion-supported-devices.html

Fusion is actually a decision tree that will select platform CV first (e.g. ARCore), Vuforia VIO second (if calibrated) and our legacy Extended Tracking (SLAM) last.

Our understanding is that ARCore started support for continuous autofocus in 1.4 - previous versions do not.

Thanks,

Thanks for letting me know. I was not sure if it was possible to combine AR Core and Vuforia scripts in the same project especially as I'm using Vuforia's AR Camera prefab. I've spotted a couple of forum posts which cover this issue if anyone is interested. Any other advice would be great haha.

The last entry in the following post pretty much asks what I'm trying to ask:

Hello @hyaqub_bmt,

Let me escalate this issue internally with a bug report.

Thanks,
