Radian Ogre::Quaternion::getRoll | ( | bool | reprojectAxis = true |

Calculate the local roll element of this quaternion.
reprojectAxis | By default the method returns the 'intuitive' result that is, if you projected the local Y of the quaterion onto the X and Y axes, the angle between them is returned. If set to false though, the result is the actual yaw that will be used to implement the quaternion, which is the shortest possible path to get to the same orientation and may involve less axial rotation. |
