Face Tracking in .NET MAUI on iOS | Community Feed

ARKit can track one or more faces in a scene, providing position, orientation, and a conforming mesh. David Britch shows how to run a face tracking session in a .NET MAUI iOS app and keep a 3D mesh aligned to the face as it moves and expresses.

What you’ll learn

Wiring up the delegate — pointing your ARSCNView at a custom ARSCNViewDelegate
Creating the face mesh — building an ARSCNFaceGeometry when an ARFaceAnchor is detected
Keeping it aligned — updating the geometry in DidUpdateNode so it follows the face
Configuring the session — enabling face tracking with ARFaceTrackingConfiguration and the front camera
Where this leads — overlaying content like glasses frames for try-on experiences

Read the full post for the complete handler and delegate code, and note that ARKit requires a physical iPhone.
