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.

Editing "Image Target Behaviour (Script)" is not possible!

August 6, 2020 - 2:04pm #1

I am using Vuforia Engine for AR development in Unity since 2017. Never have come across this warning. Though it is a warning only but what it does is that it is not allowing to launch Visual Studio when i try to Edit my "Image Target Behaviour (Script)". It says



"Unable to open Packages/com.ptc.vuforia.engine/Vuforia/Plugins/Managed/iOS/Vuforia.UnityExtensions.dll: Check external application preferences."

C++ implementation on Ubuntu 16.04

July 7, 2020 - 7:52pm #1

I am trying to build a function (to return the rotation vector and the translation vector of the marker) which can be called by another c++ program.

Requirements:

  • must be able to run on Ubuntu 16.04 (does this matter?)

Can someone guide me as to how I should start? Is this possible with Vuforia? Can I write the program in c++ and somehow make it work on Ubuntu?

I would like some sample app which I can use as a starter for the c++ program. For now, I would like to use the webcam as my camera for detection.
