Face Effects

If you want Face Effects tracking, add the xrface component to your a-scene:

<a-scene xrconfig xrface>

xrface Attributes

Component	Type	Default	Description
meshGeometry	Array	['face']	Comma separated strings that configures which portions of the face mesh will have returned triangle indices. Can be any combination of 'face', 'eyes', 'iris' and/or 'mouth'.
maxDetections [Optional]	Number	1	The maximum number of faces to detect. The available choices are 1, 2, or 3.
uvType [Optional]	String	[XR8.FaceController.UvType.STANDARD]	Specifies which uvs are returned in the facescanning and faceloading event. Options are: [XR8.FaceController.UvType.STANDARD, XR8.FaceController.UvType.PROJECTED]
enableEars [Optional]	Boolean	false	If true, runs ear detection simultaneosly with Face Effects and returns ear attachment points.

Notes:

• xrface and xrweb cannot be used at the same time.
• xrface and xrlayers cannot be used at the same time.
• Best practice is to always use xrconfig; however, if you use xrface without xrconfig then xrconfig will be added automatically. When that happens all attributes which were set on xrface will be passed along to xrconfig.

xrfaceComponent()

XR8.AFrame.xrfaceComponent()

Creates an A-Frame component which can be registered with AFRAME.registerComponent(). This, however, generally won't need to be called directly. On 8th Wall Web script load, this component will be registered automatically if it is detected that A-Frame has loaded (i.e if window.AFRAME exists).

window.AFRAME.registerComponent('xrface', XR8.AFrame.xrfaceComponent())
