operator * method

Quaternion operator *(
  1. Quaternion other
)

this rotated by other.

Implementation

Quaternion operator *(Quaternion other) {
  final double w = _qStorage[3];
  final double z = _qStorage[2];
  final double y = _qStorage[1];
  final double x = _qStorage[0];
  final Float64List otherStorage = other._qStorage;
  final double ow = otherStorage[3];
  final double oz = otherStorage[2];
  final double oy = otherStorage[1];
  final double ox = otherStorage[0];
  return Quaternion(
    w * ox + x * ow + y * oz - z * oy,
    w * oy + y * ow + z * ox - x * oz,
    w * oz + z * ow + x * oy - y * ox,
    w * ow - x * ox - y * oy - z * oz,
  );
}
