Now That a first version of Vuforia 7 (7.0.26) is out with Unity 2017.3 Is have some questions about it.
Now there is a Model Target Behavior that to my understanding should be for integrating model targets. But currently i can not find any way to create a model target. All mentionings of Model Targets do always point to the "Model Targets Early Access Program". I find id kind of wired to have a public version of unity support this feature but regular developer do not have access to it.
The Ground place was suppose to be in Vuforia Version 7 but its currently not in , guess that this will come later.
And a general technologie question: Is there the option to improve the tracking of the Image targets by extending the tracking via ARKit (or arcore) if the marker went out of view. With big 3D models on image targets you often lose sight of the image target and having a "relatively" stable tracking even if lost will be essential to make it practical.
