Callback for new position information?

[fake-name]

Is there any way I can be certain to receive every position update?

From the API structure, it seems I have to manually poll zed->getPosition() continuously. It seems like if there is another process on the computer that could preempt my application for a few tens or milliseconds, I could potentially lose position updates, which is non-ideal for my application.

Hi,

The grab() function will be the master function to tell you if a new position if available (it returns 0 when a new frame has arrived and been processed). The way to avoid losing positions will be to put the loop in a thread running continously :

the thread function could be :

while(run_)
{ 
    if (zed->grab()==0)
       zed->getPosition();
   else
       usleep(10);
}

Best, /OB/

I see. Good to know.

Thanks!
