OrientationSensor.populateMatrix()

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.

The formulas used to convert the sensor's quaternion to the provided matrix.

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
