Heavy framerate drop

By andrea.fiorito on Fri, 10/04/2013 - 13:24

Hi,

I noticed that QCAR kills the framerate of the OpenGL rendering. With Samsung Note for example, if you cover the camera with a finger (ImageTargets example) the framerate goes from 30 fps to 15. This seems related to the camera trying to focus. Now, what it would be desiderable, it would be an independence between QCAR and the framerate. Is there any simple way to achieve this goal?

Hi, Vuforia already performs many core operations (related to target detection and tracking) in a background thread, which is decoupled from the rendering;

QCAR::VideoBackgroundConfig config;
config.mSynchronous = false;
 
seems to solve the problem.
