OrientationSensor: populateMatrix() method

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

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)

Syntax

populateMatrix(targetMatrix)

Because OrientationSensor is a base class, populateMatrix may only be read from one of its derived classes.

Parameters

targetMatrix: TBD

Return value

None (undefined).
