Access Coords of Facial Features

Hey Andrew,

You can approximate the head position pretty easily using a Head Binding object.

1. Create a new Head Binding object in the Objects panel by clicking on Add New > Head Binding
2. Set its "Attach To Point" to "Forehead", and make sure "Face Index" is set to 0
3. Remove the Face Occluder child since you won't need it :)
4. Add a new child to the Head Binding object, name it something like "Head Top"
5. Position the Head Top object to the approximate top of the head. I used the local position (0, 2.4, -9.0) but you can adjust as needed. 

You can now use this Head Top object's position to approximate the top of the head. For your purpose of playing an animation based on head position, you can use a simple script to move your animation object to the head position every frame.

Add this script under the "Frame Updated" event to a parent object of your animation. Set "target" to the Head Top object created in the earlier steps.

//@input SceneObject target
script.getTransform().setWorldPosition(script.target.getTransform().getWorldPosition());

This will update your animation's position without affecting rotation. If you want the animation to always align with gravity, you can try using a Device Tracking component set to Rotation tracking mode.

Hope this helps! Let me know if you have any more questions!
