Vuforia SDK Version: 7.0.36 -
Description with steps to reproduce: 1. What happened?
When Vuforia is configured to "Track Device Pose", switching the mobile device's camera direction from Back to Front freezes the camera feed that is displayed on the scene ARCamera.
2. How we can reproduce it?
This can be reproduced with the Vuforia Core Sample Project. Just tweak the VuforiaConfiguration.asset to use Device Tracking. ie. have "Track Device Pose" enabled. and make sure the ARCamera should have "World Center Mode" = "Device_Tracking". Then just Build the Sample Project to an iOS device. When the app opens try to toggle between the front and back camera in the menu options (double tap). If it doesn't happen on the first attempt, toggle the camera direction a few times. To see that this is caused by Device Tracking, you can rebuild the project with the "Track Device Pose disabled and the bug will not occur. -
