Declaration
var lookAtPoint: simd_float3 { get }Discussion
This vector abstracts from the leftEyeTransform and rightEyeTransform matrices to estimate what point, relative to the face, the user’s eyes are focused upon. For example:
If the user is looking to the left, the vector has a positive x-axis component.
If the user is focused on a nearby object, the vector’s length is shorter.
If the user is focused on a faraway object, the vector’s length is longer.
