OrientationSensor.populateMatrix() - Web APIs 编辑

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
