Enabling/disabling Extended Tracking at runtime?

February 11, 2015 - 12:04pm #1

I found this page:

 

https://developer.vuforia.com/resources/dev-guide/extended-tracking

 

At the bottom of the page, it lists a pair of functions, StartExtendedTracking and StopExtendedTracking. However, when I tried to use these methods, they do not exist. The only members that the Trackable object contains are ID and Name.

Are these only available in certain versions of Vuforia? (I'm using 3.0.9) Or is the documentation simply referencing functions that don't exist?

Enabling/disabling Extended Tracking at runtime?

July 4, 2017 - 2:21pm #6

Hi !



I tried the method with :



ImageTargetBehaviour mTrackableBehaviour = GetComponent<ImageTargetBehaviour>();

mTrackableBehaviour.ImageTarget.StartExtendedTracking();

 

But extended tracking don't seems to work ; 

At run time, "Enable Extended tracking" is not checked on the ImageTargetBehaviour....

And also, Extended tracking don't seems to work correctly (objects disapears when image is no more tracked)

Is there a bug on this feature ?

 

EDIT : Sorry, my bad. Problem was on my side. Nevermind.

Our API now has search field to make it easier to find content. Here is the ExtendedTrackable class:

Page not Found, three links

Vuforia 6 came out, these do not exist anymore.

Vuforia guide to EnableDisable is outdated.

Please update your information

The methods are declared in ExtendedTrackable:

When you get back a TrackableBehaviour, you can access its Trackable. If the Trackable is an ExtendedTrackable, you can call the methods to start and stop Extended Tracking.
