Quaternion operator *(
  1. Quaternion other
)

this rotated by other.

Implementation

Quaternion operator *(Quaternion other) {
  final _w = _qStorage[3];
  final _z = _qStorage[2];
  final _y = _qStorage[1];
  final _x = _qStorage[0];
  final otherStorage = other._qStorage;
  final ow = otherStorage[3];
  final oz = otherStorage[2];
  final oy = otherStorage[1];
  final 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);
}
