OrientationSensor: populateMatrix() method - Web APIs | MDN
OrientationSensor: populateMatrix() method Limited availability
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)
populateMatrix(targetMatrix)
Because OrientationSensor
is a base class, populateMatrix
may only be read from one of its derived classes.
