The populateMatrix method of the OrientationSensor interface populates the given target matrix with the rotation matrix based on the latest sensor reading. The rotation matrix is shown below.

where:
- W = cos(θ/2)
- X = Vx * sin(θ/2)
- Y = Vy * sin(θ/2)
- Z = Vz * sin(θ/2)
If a feature policy blocks use of a feature it is because your code is inconsistent with the policies set on your server. This is not something that would ever be shown to a user. See Feature-Policy for implementation instructions.
Syntax
