Extended track and persist map

Hi @micah ,

so far I know there is no addtional documentation to the mention help link.

When we consider the 3d Conatiner widget property we can observe a difference between the HoloLens and mobile device:

So,we can see that the is properties are only available to set to the mobile devices. On HoloLens this options are always used - the HoloLens created always persistent map on the environment and used Extended tracking.

Extended Tracking is quite useful when the Target (e.g. Thingmark) itself will not move with respect to the rest of the environment. Vuforia will use the surroundings of the ThingMark to "remember" where the ThingMark is, even if it is not on camera. This is also for other kind of Targets when the devices itself has an AR support and it is able to generate a map on the environment outside the target. So means in this case you  have to move slow many time the device to scan the environment so the device could generate a persistent map- means you can move away the device and when you return back  and scan again the  location (where you generated already a map) it will remember the position - so without viewing the target itself

But if the mobile device does not support the generation of persistent map – the setting will not have any effect

According a  development comment:

Extended tracking cannot be turned off while using model targets.  Vuforia documentation on this notes "Extended tracking is always on on supported devices and can’t be changed at run-time. "

Also the following post did handle similar question : https://community.ptc.com/t5/Vuforia-Studio/Thingmark-loses-track/m-p/547838

I want here to point to the following links (Vuforia Development portal) which still has relevance also for Studio. This are some very helpful guidelines on the Vuforia development library side . Some of the features are common and are also valid  for Studio
