iOS UIView issue

December 1, 2017 - 10:53am #1

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.

Video Playback Streaming Render To Texture

October 13, 2014 - 12:04am #1

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,

iOS App Store Privacy Settings

SDK 9.8
August 30, 2021 - 4:33am #1

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

SDK 9.8
August 10, 2021 - 4:21pm #1

Hello,

 

Release notes show that the latest iOS SDK is 9.8.11 (with some patch level), but the SDK download screen only gives me 9.8.5.

 

Where can we get the latest?

 

Thanks

Convert image target point to screen point

July 27, 2021 - 10:34pm #1

iOS 14.x

Vuforia SDK 9.8.5

 

How can we convert model coordinates to iOS UIView view/screen coordinates?

Can someone (Vuforia?) provide some sample code, for iOS (and ideally Android) native, that will consistently and reliably convert a point in the recognized image target's coordinate space to X,Y CGPoint location within the UIView where the CAMetalLayer is rendering Vuforia?

How to preload image targets - slow load time

July 27, 2021 - 10:04pm #1

I'm using SDK 9.8.5 on iOS (native).  

We've got a large dataset that we load (hundreds of image targets), and this loading process takes a long time.  Even if we load from a local file that's in our app bundle, this can take up to 10 seconds on an iPhone X.  This means that while it's loading, we can (A) show the user a loading screen, or (B) show them a live camera that won't recognize any targets.  Neither of these options is good.

Renders incorrectly in all device orientations except landcapeRight (ios native demo app)

July 27, 2021 - 9:23pm #1

We've been working with iOS native SDK 9.8.5 and the corresponding sample/demo app.

The demo app is locked to landscapeRight orientation -- that is, the landscape orientation where the charging port is to the right.

In our app, we want the user to be able to generally use the device in portrait orientation.  We were having trouble with Vuforia rendering correctly, so we want back to the demo app to try it out there.

For example:

objc_sync_enter/exit AND DispatchSemaphore in native demo app?

July 27, 2021 - 9:09pm #1

We're working with iOS SDK 9.8.5 (native -- not Unity), and are trying to understand the sample app.

In VuforiaView.swift, there is this:

 

    @objc func renderFrameVuforia() {
        objc_sync_enter(self)
        if (mVuforiaStarted) {
            
            if (mConfigurationChanged) {
                mConfigurationChanged = false
                configureVuforia()
            }
            
            renderFrameVuforiaInternal()
        }
        objc_sync_exit(self)
    }
