Custom android vuforia drivers

June 6, 2021 - 9:47am #1

Hello Vuforia Team,


I have a java android application in which I get YUV frames from another device and I want to parse those frames into Vuforia and use Unity.


I have gone through the following pages but I am not sure if the proper solution is by using this : vuforia-driver-sample-drivertemplate-x-x-x

or vuforia-driver-sample-uvcdriver-android-x-x-x

Image Target Multiple Pictures

May 10, 2021 - 1:39pm #1


I'm trying to build an AR app that can recognize multiple pictures. I'm using Image Target and device database. I'm always adding manually to the Scene a new Image Target for every picture from the database. This process is too tedious, what can I do if I'm having like 100 pictures? Why can't a single Image Target recognize all the images from the database. How can I make this process more dynamic or at least at runtime I guess.

Experience inconsistency in adding markers to cloud database

March 10, 2021 - 1:02pm #1

Dear Vuforia Support,


We have an automated test that adds several imagetarget / markers to a cloud database. But after the update last (maintenance Vuforia) we experience that some of the markers can be added and some result in an error.

Also cases that the TargetID can not be found but we see the targetId in de web portal of Vuforia in our cloud database.

Any idea if also other developers experience this?

Depth Scan

March 7, 2021 - 9:03am #1


Is there any way to scan depth dynamically just like AR Core? I'd like to generate meshes for physics simulation in my Unity app, as well as for dynamic object occlusion.

See what I mean in action here: .

Engine key

February 24, 2021 - 8:27am #1


We used Vuforia for the first time last year. We entered the key in our apps.

Will this key change when we renew our current contract? Or will the key remain the same?

If it's another key, than we need to update our app and push it back to the stores...


Kind regards

How do I make a model change when two targets come in contact

February 4, 2021 - 10:55pm #1

I am building a chemistry game where you can mix chemicals by putting two or more cards together. How do I make the model above a card change if two cards come in contact with each other?
