AugmentedFaceNode

Page Summary

AugmentedFaceNode renders visual effects on a face detected by ARCore, using a face mesh for 2D images and a face regions renderable for 3D objects.
Visual effects are achieved by mapping 2D images onto the face mesh and attaching 3D objects to tracked face regions using a rigged model.
The node's position is automatically synchronized with the tracked face's pose, and effects are disabled when tracking is lost.
Developers can customize the appearance of the face mesh by overriding its material or applying a texture, while 3D object rendering is controlled through a separate ModelRenderable .
AugmentedFaceNode provides methods to manage the associated AugmentedFace , control visual effect components, and respond to lifecycle events.

public class AugmentedFaceNode

Node used to render visual effects on a face with ARCore's AugmentedFace feature.

The visual effects can consist of up to two components: The face mesh and the face regions renderable.

The face mesh is used for visualizing 2d images mapped to the surface of someone's face. The face regions renderable is used for visualizing 3d objects (e.g. fox nose and ears) that will move with the regions of the face that are tracked by ARCore.

When creating a face regions Renderable, the regions are mapped to bones in the model. Use the provided sample .fbx file to export a face regions renderable in the correct format.

This node is positioned to match the pose from getCenterPose() .

The visual effects will be disabled when the AugmentedFace isn't tracking or the AugmentedFace is set to null.
