[=&;;;;;;quot]What is Augmented Reality?[/][=&;;;;;;quot] [/][=&;;quot]Augmented reality technology places virtual content in a live camera view of the real world, thus creating an augmented world where virtual and real world elements appear to coexist. A device, such as a mobile phone, acts as the looking glass through which this this augmented world may be viewed.[/][=&;;;;;;quot] What is a trackable? A trackable, also known as a target, is a key element of vision-based AR.

Hi, I'm belatedly upgrading my app framework to Vuforia 8 from Vuforia 6. I have successfully got the tracked objects placed where they appear with V6, but when not tracking I'm getting a different projection matrix between the versions, so my non-tracked objects are placed differently.:

The code is given below, and called at screen re-orientation. 

I wouldlike to know how vuforia plays video inside target, technical discussion

Hello！ I have a  question about the extrinsic matrix from the real object coordinate to the camera coordinate.

I check the API reference in C++， there is a function named getPose() in TrackableResult class.

TrackableResult.getPose();

But I am using unity/C# , so is there a  corresponding function to get the extrinsic matrix from the real object coordinate to the camera coordinate using unity API?

THANKS!

Hi, dear Vuforia community.

I need to manually control exposure settings like enabling exposure lock and calculate exposure based on a pre defined center area.

CameraDevice.Instance.GetCameraFields() never returns anything for my Android devices and CameraDevice.Instance.SetField() does not seem to work. (Might be because I don't know the correct device keys)

Hi, dear Vuforia community.

We use outside image markers which are pretty far away, this makes them prone to jitter and that would be just fine if we could disable tracking of the marker once it is recognized and then switch to rely solely on extended tracking.

So, is there a way to force extended tracking manually whenever we need it?

I don't mind hacking it through reflection or Unity's SendMessage to private methods, or decompiling Vuforia for information to get it working.

Thanks!

Hello !

I was wondering if Vuforia is capable of detecting a landmark (ImageTarget) while using a video from a 360 video camera ?

Thanks for the help in advance !

Hello,

A problem I have not been able to solve for a week now:

How do I go from an AR ExtendedTracking scene to a VR scene? Does anyone have an example for me?

Unity 2019.1.4f1 | Vuforia 8.1.11

More precisely, as I understand it:

 HI, 

I'm newbie in Vuforia and I can't understand why my code make properly only one. 

The imageTarget object is taking only once, then I see some paint in scene.

That one painting point is rotate properly with the userImageTarget.

Every next paiting point appear but rotate only with device, independently my userImageTarget,

but the new object paint (represent clone object) have a parent from  imageTarget.

Unfortunately new pait object haven't any parent, I don't know what I should to do.

We are developing AR application using vuforia in Unity.

The camera is out of focus and the marker can not be read.

Is there a function that brings the focus of the camera to the position you tap on your smartphone?
