Properties​

worldPosition?​

optional worldPosition: Vector3

Defined in: src/world/faces/DetectedFace.ts:28

The back-projected 3D position in WebXR world space, measured in meters. Null or undefined if depth projection was unsuccessful.

x​

x: number

Defined in: src/world/faces/DetectedFace.ts:12

Normalized horizontal coordinate [0.0, 1.0] in screen space, where 0.0 is the left edge and 1.0 is the right edge.

y​

y: number

Defined in: src/world/faces/DetectedFace.ts:17

Normalized vertical coordinate [0.0, 1.0] in screen space, where 0.0 is the top edge and 1.0 is the bottom edge.

z​

z: number

Defined in: src/world/faces/DetectedFace.ts:23

Raw estimated depth value relative to the camera. Smaller magnitude means closer to the camera; the value is in the same arbitrary normalized space as x and y.
