Summary
In this chapter, you built a face maker app that handles face tracking with the forward-facing (user-facing) camera on a mobile device. You learned that the AR Face Manager component takes a Face Prefab to instantiate when a face is tracked. You first used that to visualize specific AR Face prefabs but then created a generic Changeable Face Prefab with a ChangeableFace script that we could update from the FaceMainMode script.
You used this architecture to explore several ways of rendering tracked faces. First, you used the face pose to render an instantiated 3D head model (MrPlasticHead and MrFacetHead). Next, you used this technique to add accessories to the face, including a TopHat and Sunglasses. Then, you added an AR Face Mesh Visualizer to generate a face mesh dynamically at runtime, and then made several materials that can be applied to the mesh to make a wide variety of face masks. If you're on ARCore, you also implemented face region stickers using sprite images...
