Hello,

Please find the native (C++) API documentation for the pre-10.0 Engine release (v9.8) here:

Hello,

Attached is Vuforia’s version of the app-level fix scripts provided by @adrianj (many thanks!) in the following forum thread. This can be used immediately with SDK 6.5 (Unity 2017.2), SDK 7.0 (Unity 2017.3) and SDK 7.1 (Unity 2018.1).

Here are the recommended steps for installing and enabling:

1. Back up your project
2. Import the attached DelayedVuforiaInitialization.unitypackage
3. In the first scene that uses Vuforia, attach the VuforiaInitialization.cs script to any active game object, e.g. the ARCamera
4. In the Vuforia configuration (Menu: Window -> Vuforia Configuration) and check “Delayed Initialization”

IMPORTANT: In case your application logic relies on Vuforia being initialized and started at scene startup, you may have to adapt that code. The best way to do this is to listen for the VuforiaStarted callback using: VuforiaARController.Instance.RegisterVuforiaStartedCallback(…);

We are also working on rolling out a similar fix via patch releases for SDK 7.0 and 7.1. Note that for 7.0 patch availability, we are reliant upon Unity's timing for releasing updates. Patching Vuforia 7.1 SDK will be done via installer functionality built into the Editor.

Lastly, contrary to previous Vuforia communications, we *will not* be providing patch releases for SDK 6.2 and 6.5. This is due to multiple factors, including Unity not providing long-term support for Unity 2017.2 (SDK 6.5) and earlier versions. We recommend that if you're still using Vuforia 6.2, you follow similar app-level logic in the attached scripts.

Thanks,

Vuforia Support

Hello all,

I wanted to bring to attention an iOS issue you may encounter that will cause reduced performance within your app. This can occur either with native iOS or Unity development.

In native development, if you are not using a storyboard, you’ll need to set the ‘backgroundColor’ field of any UIView you generate with code to ‘UIColor.clearColor’ to get around a known iOS issue. If you are using a storyboard, you will not encounter this issue and will not need to add any code.

If you’re developing in Unity, you can make this same change within the generated XCode project. Open the file called UnityAppController.mm and navigate to the ‘didFinishLaunchingWithOptions’ function. The following code is present on lines 243 and 244:

_window         = [[UIWindow alloc] initWithFrame: [UIScreen mainScreen].bounds];
_unityView      = [self createUnityView];

Adding the following line after these lines will resolve this issue on Unity generated projects:

_unityView.backgroundColor = UIColor.clearColor;

Keep in mind that since this is in a generated project, if you aren’t selecting to append the project when building from Unity this will be overwritten anytime you regenerate the XCode project.

Thanks for you continued interest in Vuforia,

Hello,

I would like to have some video streamed and played on top of a recognized image, not in full screen. The vuforia samples as of this date do not seem to indicate that something like this is possible, or at least, they haven't created a sample with that.

I found this link,

https://developer.vuforia.com/forum/vuforia-developer-opportunities/development-partner-ios-videomovie-texture-lib-mp4movm4v

but it seems a little bit outdated, as many files are missing. 

Therefore, here are my questions:

-- Is there any simple way of making this work?

-- If not, Has anyone tried using "AVPlayerItemVideoOutput" in order to have the AVPlayer stream the video, grab the OpenGL data from it and render it on a vuforia - provided texture? Would something like this work?

I would appreciate any thoughts on the matter.

Given below when trying to publish my application in apple store these error arises

"Command PhaseScriptExecution failed with a nonzero exit code" at the end

I made basic AR app both Android and and iOS with the same* Unity settings. Android is OK but on the iOS side I have a big problem.

When I move around with device, object is moving slightly with me. I mean the model is not stable. 

It might be an ARKit issue but couldn't find any answer. Is there any guide to fix this issue

Hi,

I am having an issue with my app where it seems to crash and not work anymore after I’ve added a certain number of image targets. The app used to work just find and display the right stuff and everything for the first 10 image targets or so, but now I cannot get it to work with like 20 image targets. I’ve tested either set of 10 and both work fine on their own, but the app cannot seem to handle them all.

For context, I’ve tried deleting the associated images, text, and videos that are supposed to show with each image when tracked in a variety of different ways but the app will still not work when all 20 target images are in the app.

Does Unity/Vuforia have some issue with having too many image targets?

Thanks for any help!

Hi Everyone,

I am trying to develop my first App and am using Vuforia with a model target.

I have a script that uses raycast to detect objects.

For a bloom effect that I want to achieve I added the URP (Universal Render Pipeline) addin.

When I test the App directly in Unity on my Macbook everything looks just perfect.

However when I write the App to my IPhone via XCode, the result has some error.

The screen starts flickering in all kind of colors from red, blue, green, yellow.

What I noticed is that if I direct the camera to a "quite" aim like a wall it stops flickering, if i direct it to an area where a lot is going on like in the screenshot it starts flickering heavier, almost like you can see it calculating...

So when I switch off the PostProduction in the (Vuforia)Camera the bug does not appear.

Please have a look at the screenshot attached.

I would be happy for any hint, how to fix this.

I also googled a lot for this bug but didn`t find anything comparable.

Thx, Jonathan

Hi there !

I wanted to know if those are the correct privacy settings for an App that uses Vuforia 9.8 and which had all data collection disabled except for Vuforias' built in?

As i am not 100% sure what Vuforia is actually using the statistics for that they acquire as stated here : 

https://developer.vuforia.com/legal/statistics

I've uploaded a screenshot of the settings i currently have, please view the attachment.

Best regards
