populateMatrix method

void populateMatrix(
  1. RotationMatrixType targetMatrix
)

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)

Implementation

external void populateMatrix(RotationMatrixType targetMatrix);
