Unity has already released the beta version 2019.2 and has a lot of new AR Foundation toys to test.
Among the new features supported by the Unity platform's mobile AR frames
With face tracking , developers can activate their apps to detect faces and construct meshes to make face animations. The feature includes a "face manager" that takes care of the device configuration and creates content for identified faces.
Similarly, 2D image tracking uses a "tracked image tracker" that builds 3D content based on recognized images. Developers can also trigger another AR experience based on changes in the tracked image.
In addition, 2019.2 beta provides support for 3D object tracking and environmental probes for ARKit. The former allows developers to load 3D files representing physical objects for mobile AR apps, while the latter helps mix 3D content in the real world based on lighting and color measurements. Similarly, these features have managers to customize 3D content and information with environmental data.
The new features, along with the existing portfolio of AR Foundation features, are available in preview. Unity plans to make AR Foundation a standard feature with the release of 2019.2, so the combined set of tools prepares the framework to cover most ARKit and ARCore features.
As reality platforms, tools that AR Foundation becomes crucial. By giving developers the opportunity to build an AR experience for both iOS and Android, app publishers no longer need to choose between mobile ecosystems or invest extra efforts to create two different versions of the same experience.
