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?

Vuforia::init takes long time on restricted network

October 2, 2020 - 6:27am #1

Hi, I have an application that init and deinit a lot when switching views and I encountered a problem if the network that the device connects has restricted (outgoing/incoming traffic blocked) or no internet access. 

From what I was able to establish Vuforia::init takes ~10 seconds to return 100 result with blocked ethernet connection while with unblocked or no connection it takes ~1 second.

remove response header

September 17, 2020 - 9:43am #1

Hello guys, im using vws in php, the response header is showing in my cms, i need is to remove this response.

Exemple of the response shown in html :


 GET d41d8cd98f00b204e9800998ecf8427e Thu, 17 Sep 2020 16:34:20 GMT /targets

i think " request->send(); " is responsible, i just don't know how to remove headers.
