Any tracking feature (image, model, cloud, etc…) is associated with a Feature Observer, which is the actual Object responsible for tracking the target and reporting its pose info. This is called in our Vuforeal Plugin a “Vuforeal Observer”, which is similar to the Vuforia Observer.
More details can be found in the Vufoia and Vuforeal Design articles.
Regardless of the method you are using to activate a tracking feature, you’ll always get a “Vuforeal Observer” for each Target you want to track.
In this section, we will explain how to get a reference to these objects, for each tracking feature and using each activation method, as well as how you can control the observers’ activities and get their tracking info.
